Description

本発明は、搾乳時に***を温める搾乳用加温具、及びこれを利用した搾乳器に関する。   The present invention relates to a heating device for milking that warms a breast during milking, and a milking device using the same.

乳児に直接母乳を与えることが困難な場合、乳頭が傷ついている場合、乳腺炎を予防する場合などに、母乳を取り出す搾乳器が用いられている。
この搾乳器は、***を覆う搾乳口を有する漏斗状のフード部と、このフード部が接続されると共に、搾乳した母乳を貯留する容器が接続される搾乳器本体と、この搾乳器本体を介して搾乳口で囲まれた空間に負圧を与えたり解除しりするためのポンプ部とを有している。 A breast pump that removes breast milk is used when it is difficult to give breast milk directly to an infant, when the nipple is damaged, or when mastitis is prevented.
This milking machine has a funnel-shaped hood part having a milking mouth that covers the breast, a milking machine main body to which the hood part is connected and a container for storing milked milk, and a milking machine main body. And a pump unit for applying or releasing negative pressure to the space surrounded by the milking mouth.

このような搾乳器を用いて搾乳をする際、使用者は***を搾乳口に密着させて使用するため、冷たい搾乳口が***を冷やすことになる。この***の冷えは、血行を悪化させて血液の量が減ることで母乳の出を悪くさせ、また、***に急に冷たい搾乳口を接触させることで緊張状態を生じさせ、この緊張により、母乳を出すためのホルモンが減少することも分かってきた。このため、搾乳する際は、搾乳口は適度に温められているのが好ましい。   When milking using such a breast pump, the user uses the breast in close contact with the milking mouth, so the cold milking mouth cools the breast. This coldness of the breast worsens blood circulation and reduces the amount of blood, which makes the milk output worse, and suddenly touches the breast with a cold milking mouth, creating tension, which causes breast milk It has also been found that the hormones used to release the drug decrease. For this reason, when milking, it is preferable that the milking mouth is warmed moderately.

従来、搾乳口を加温するための装置としては、例えば特許文献１に示すブレストキャップがある。即ち、特許文献１の図１に示されるように、ブレストキャップ（フード部）の***と接触する内面には、薬用パラフィン等の蓄熱材であるゲル状の抵抗発熱体が収容されたパッド１６が設けられている。そこで、使用者は、搾乳前にこのパッド１６を湯で加温するなどして温め、これにより搾乳時の冷えを解消させている。
また、特許文献１では、その図２に示されるように、ブレストキャップには、パッド１６だけではなく、抵抗電熱線からなる加温器９も有している。これにより、パッド１６が冷えてきても、加温器９に電力供給して発熱させ、これにより、搾乳中であっても***の冷えを解消させている。なお、抵抗電熱線からなる加温器だけで***を温める従来の搾乳器については、例えば特許文献２もある。 Conventionally, as an apparatus for heating a milking mouth, there is a breast cap shown in patent documents 1, for example. That is, as shown in FIG. 1 of Patent Document 1, a pad 16 in which a gel-like resistance heating element, which is a heat storage material such as medicinal paraffin, is accommodated on the inner surface of the breast cap (hood portion) in contact with the breast. Is provided. Therefore, the user warms the pad 16 with hot water before milking, thereby eliminating the cooling during milking.
In Patent Document 1, as shown in FIG. 2, the breast cap has not only the pad 16 but also a heater 9 made of a resistance heating wire. Thereby, even if the pad 16 is cooled, electric power is supplied to the heater 9 to generate heat, thereby eliminating the cooling of the breast even during milking. In addition, about the conventional milking machine which heats a breast only with the heater which consists of resistance heating wires, there exists patent document 2, for example.

特許第４４３１５８３号公報Japanese Patent No. 4431583 特表２００９−５２０５２４号公報Special table 2009-520524 gazette

ところで、特許文献１の図１に示す薬用パラフィン等が収容されたパッド１６による蓄熱材方式では、パッド１６を湯等で温める必要があり、温めるのに時間がかかって、その作業が大変である。しかも、パッド１６は直ぐに冷えてしまうため、結局、特許文献１の図２に示すように、抵抗電熱線からなる加温器をフード部に設ける必要がある。
しかし、この抵抗電熱線による電気ヒーター式では、搾乳中に搾乳口に通電をする必要があり、電源を必要としない手動式搾乳器には使用できない。また、電動式搾乳器についても、抵抗電熱線が見えただけで使用者は緊張をし、このちょっとした緊張感が母乳の出を悪くさせる原因につながってしまう。母乳の出は精神状態に相当に左右されるものである（特許文献２も同様に電気ヒーター式であり、同じ問題が存在する）。更に、電気ヒーター式では薬液及び煮沸消毒を行うこともできない。
なお、発明者は、その他にも蒸しタオル・湯たんぽ・カイロ方式などの様々な方式を試みたが、いずれも加温に時間がかかったり、温度が直ぐに低下したりするなどの問題があることが分かった。 By the way, in the heat storage material method by the pad 16 in which the medicinal paraffin etc. which were shown in FIG. 1 of patent document 1 were accommodated, it is necessary to heat the pad 16 with hot water etc., and it takes time to warm, and the operation | work is difficult. . In addition, since the pad 16 cools down immediately, it is necessary to provide a heater composed of a resistance heating wire in the hood portion as shown in FIG.
However, this electric heater type using a resistance heating wire needs to energize the milking mouth during milking and cannot be used for a manual breast pump that does not require a power source. In addition, with regard to the electric milking machine, the user is tense just by seeing the resistance heating wire, and this slight tension leads to the cause of worsening the milk output. Breast milk output depends considerably on the mental state (Patent Document 2 is also of the electric heater type and has the same problem). Furthermore, the chemical heater and boiling sterilization cannot be performed with the electric heater type.
In addition, the inventor tried various other methods such as a steaming towel, hot water bottle, and warmer method, all of which have problems such as the time required for heating and the temperature dropping immediately. I understood.

本発明は、以上の事情に鑑みてなされたものであり、直ぐに温められ、かつ、その温度を可及的に維持でき、さらに、搾乳口を***に当てた際の緊張感を緩和する***加温具、及びこれを利用した搾乳器を提供することを目的とする。   The present invention has been made in view of the above circumstances, can be warmed immediately, can maintain the temperature as much as possible, and can further reduce the tension when the milking mouth is applied to the breast. It aims at providing a warming tool and a milking machine using the same.

上記課題は、本発明によれば、搾乳時に***を覆う搾乳口に接続され、前記搾乳口よりも高い温度で発熱する発熱部を備えた搾乳用加温具であって、前記発熱部は、マイクロ波エネルギーを吸収して発熱するフェライトを有し、前記発熱部を熱硬化性樹脂で被覆することで、搾乳時における前記搾乳口を介した又は直接的な***への接触温度が、***の温度以上であって、かつ、低温火傷をしない温度以下となるように、前記発熱部から***に伝達される温度を低下させる被覆部を有する搾乳用加温具により解決される。   According to the present invention, the above-described problem is a milking warming device that is connected to a milking mouth that covers a breast at the time of milking and includes a heat generating part that generates heat at a temperature higher than that of the milking mouth. By having ferrite that absorbs microwave energy and generating heat, and covering the heat generating part with a thermosetting resin, the temperature of contact with the breast through the milking mouth or directly during milking is reduced. This is solved by a milking warming device having a covering portion that lowers the temperature transmitted from the heat generating portion to the breast so as to be equal to or higher than the temperature and equal to or lower than the temperature at which low temperature burns are not caused.

本発明の構成によれば、搾乳口よりも高い温度で発熱する発熱部を備えた搾乳用加温具は、搾乳時に***を覆う搾乳口に接続されるため、例えば搾乳口の外周面側に接続すれば、搾乳口を温めて***の冷却を防止することができる。また、搾乳口の内周面側に接続すれば、暖かい搾乳用加温具を直接、***に接触させて、***の冷却を防止できる。なお、本発明の搾乳用加温具の搾乳口への接続構造は着脱式と固定式のいずれあっても構わない。
ここで、発熱部は、マイクロ波エネルギーを吸収して発熱するフェライト（酸化鉄）を有している。従って、使用者は発熱部を電子レンジで短時間に加熱することができる。また、このフェライトが配合された発熱部は、搾乳時間に対応した長い時間（例えば片胸に約１０分）、少なくとも温度が大きく低下する事態も防止できる。
ところで、フェライトは食品を加熱する等の利用方法が多く、一般的なフェライトを配合した発熱部では逆に温度が高過ぎることになる。しかし、本発明の構成によれば、搾乳時における搾乳口を介した又は直接的な***への接触温度が、***が低温火傷をしない温度となるように、発熱部から***に伝達される温度を低下させる被覆部を有している。従って、この被覆部が緩衝材になって、長い時間搾乳しても、***の低温火傷を防止できる（例えば、該接触温度を４６℃となるように被覆部を厚くすれば、３０分程度は皮膚に接触させ続けても低温火傷にならず、安全率を見て長い搾乳時間であったとしても低温火傷を確実に防止できる）。
また、この接触温度は、***の温度以上であれば、少なくとも搾乳口を***に接触させた際のヒヤッと感から生じる緊張を回避して、ホルモン分泌の減少を防止することもできる。なお、緊張感について言えば、抵抗電熱線もないので、それだけでも使用者の緊張感を緩和できる。
しかも、この被覆部は熱硬化性樹脂であるため、発熱部を電子レンジで加熱する際に変形・溶融することもなく、例えば、搾乳口に対して着脱可能に接続する場合は、搾乳口に合った適切な形状を保持できる。
さらに、この搾乳用加温具は樹脂製の被覆部で覆われているため、搾乳用加温具の搾乳口への接続構造が着脱式と固定式のいずれを問わず、薬液及び煮沸消毒を行うこともでできる。
なお、上記「***への接触温度」は、好ましくは***に最初に接触する温度であるが、多少前後しても構わない。また、搾乳している最中に***から搾乳口を長時間外し、再び***に接触する際の接触温度は除かれる。 According to the configuration of the present invention, the milking warming device including the heat generating portion that generates heat at a temperature higher than the milking mouth is connected to the milking mouth that covers the breast at the time of milking. If connected, the milking mouth can be warmed and the cooling of the breast can be prevented. Moreover, if it connects to the inner peripheral surface side of a milking opening, the warming heating tool for milking can be made to contact a breast directly and cooling of a breast can be prevented. In addition, the connection structure to the milking opening of the heating device for milking of the present invention may be either a detachable type or a fixed type.
Here, the heat generating part has ferrite (iron oxide) that absorbs microwave energy and generates heat. Therefore, the user can heat the heat generating portion with a microwave oven in a short time. Moreover, the exothermic part with which this ferrite was mix | blended can also prevent the situation where temperature falls at least for a long time (for example, about 10 minutes for one breast) corresponding to milking time.
By the way, ferrite is used in many ways, such as heating food, and the temperature is too high in a heat generating part containing general ferrite. However, according to the configuration of the present invention, the temperature transmitted from the heating part to the breast through the milking mouth or directly at the time of milking is such that the temperature at which the breast does not cause low-temperature burns. It has the coating part which lowers. Therefore, even if milking for a long time, this covering part can be used as a cushioning material to prevent low-temperature burns of the breast (for example, if the covering part is thickened so that the contact temperature is 46 ° C., about 30 minutes) Even if it keeps coming into contact with the skin, it does not cause low-temperature burns, and even if the milking time is long due to the safety factor, low-temperature burns can be reliably prevented).
Further, if the contact temperature is equal to or higher than the temperature of the breast, it is possible to avoid a decrease in hormone secretion by avoiding at least tension generated when the milking mouth is brought into contact with the breast. Speaking of tension, there is no resistance heating wire, so that it can alleviate the tension of the user.
In addition, since this covering portion is a thermosetting resin, it does not deform or melt when the heating portion is heated in a microwave oven.For example, when connecting removably to the milking mouth, A suitable shape can be maintained.
Furthermore, since the heating device for milking is covered with a resin coating, the connection structure to the milking mouth of the heating device for milking is either removable or stationary, You can also do it.
The “contact temperature to the breast” is preferably a temperature at which the breast is first contacted, but may be slightly different. In addition, the milking mouth is removed from the breast for a long time during milking, and the contact temperature when it comes into contact with the breast again is excluded.

また、好ましくは、前記被覆部は、前記搾乳口の前記***が接触する内周面とは反対側の外周面に配置されることを特徴とする。
そうすると、搾乳口の外周面に配置された搾乳用加温具の発熱部の熱は搾乳口を介して***へ伝達するため、被覆部だけではなく搾乳口も熱的な緩衝材になる。従って、搾乳口が緩衝材になる分、被覆部の厚みを抑制でき、搾乳用加温具の重量を抑えて、使用者の搾乳による疲れを軽減できる。 Moreover, Preferably, the said coating | coated part is arrange | positioned at the outer peripheral surface on the opposite side to the internal peripheral surface where the said breast of the said milking mouth contacts.
If it does so, since the heat | fever of the heat generating part of the heating tool for milking arrange | positioned at the outer peripheral surface of a milking mouth will be transmitted to a breast via a milking mouth, not only a coating | coated part but a milking mouth will also become a thermal buffer material. Accordingly, the thickness of the covering portion can be suppressed by the amount that the milking mouth becomes a cushioning material, the weight of the heating tool for milking can be suppressed, and fatigue caused by milking of the user can be reduced.

また、好ましくは、前記被覆部の前記搾乳口側と反対側の表面温度は、前記接触温度と同等以上であって、かつ、適正に発熱した前記搾乳用加温具が手に触れることで低温火傷をしない温度以下とされていることを特徴とする。
従って、加熱した搾乳用加温具の温度を搾乳前に手で容易に感じられるようにして、火傷を未然に防止できる。
即ち、もしも、加熱部から被覆部の搾乳口と反対側の表面までの厚みを大きくして、該表面に手を当てて余り熱を感じられなくしてしまうと、加熱し過ぎた発熱部に気づかずに、搾乳口を介して***に接触させてしまうことになり、火傷の危険がある。なお、このことは搾乳用加温具の搾乳口への接続構造が着脱式である場合も固定式である場合も同様である。
そこで、例えば被覆部の搾乳口と反対側の表面と発熱部との厚み方向の寸法を大きくせずに、あえて該表面の温度を***への接触温度と同等以上にすることによって、使用者は加熱した搾乳用加温具の温度を搾乳前に手で容易に感じられるようにした。従って、例えば搾乳用加温具が着脱式であれば、過熱した搾乳用加温具の搾乳口への装着を躊躇させて、***の火傷を未然に防止できる。また、固定式でも、搾乳口を***にあてがう前に過熱した温度を感じて、***の火傷を未然に防止できる。
また、被覆部の該表面温度は、適正に発熱した搾乳用加温具を搾乳口に装着する際に低温火傷をしない温度以下とされているので、例えば搾乳用加温具が着脱式であっても、手を火傷することなく搾乳口に装着できる。なお、上記「適正に発熱」とは仕様に反した異常な使い方を除く趣旨であり、搾乳用加温具を仕様にそって電子レンジで加熱し、搾乳用加温具の搾乳口を介した***への接触温度が低温火傷しない温度以下となっている状態における発熱を指す。 Preferably, the surface temperature of the covering portion on the side opposite to the milking mouth side is equal to or higher than the contact temperature, and the milking warming tool that has appropriately generated heat is touched by a low temperature. It is characterized by being at a temperature that does not cause burns.
Therefore, the temperature of the heated milking warming device can be easily felt by hand before milking, and burns can be prevented.
That is, if the thickness from the heating part to the surface opposite to the milking mouth of the covering part is increased and the heat is not felt by touching the surface, the overheated heating part is noticed. Without touching the breast through the milking mouth, there is a risk of burns. In addition, this is the same also when the connection structure to the milking opening of the heating tool for milking is a detachable type or a fixed type.
Therefore, for example, without increasing the dimension in the thickness direction of the surface opposite to the milking mouth of the covering part and the heat generating part, the user dares to make the temperature of the surface equal to or higher than the contact temperature to the breast. The temperature of the heated milking heating tool was easily felt by hand before milking. Therefore, for example, if the milking warming device is a detachable type, it is possible to prevent the breast from being burned by making the overheating milking warming device worn on the milking mouth. In addition, even with the fixed type, it is possible to prevent the burn of the breast in advance by feeling an overheated temperature before applying the milking mouth to the breast.
In addition, the surface temperature of the covering portion is set to a temperature that does not cause low-temperature burns when a properly heated milking warming device is attached to the milking mouth. For example, the milking heating device is detachable. But you can put it on the milking mouth without burning your hands. In addition, the above-mentioned “appropriate heat generation” is intended to exclude abnormal usage that violates the specification, and the heating device for milking is heated in a microwave oven according to the specification, and the milking heating device is passed through the milking mouth. It refers to fever in a state where the temperature of contact with the breast is below the temperature at which low temperature burns do not occur.

また、好ましくは、前記被覆部はシリコーン樹脂製であって、前記発熱部から前記外周面側の面までの厚み方向の寸法が略１〜２ｍｍであり、前記発熱部は、シリコーン樹脂に前記フェライトを配合した略０．５〜１ｍｍの厚みを有する板状体であり、前記発熱部を構成する前記シリコーン樹脂と前記フェライトの重量比は略６：１〜９：１であることを特徴とする。
かかる構成であれば、電子レンジにより迅速に（例えば５００Ｗの出力の電子レンジであれば６０秒前後で）有効な加熱が可能になると共に、搾乳口を介した***への接触温度を心地よい温度にして母乳の出を促進することができる。
即ち、***の低温火傷を防止するだけであれば、例えば発熱部のシリコーン樹脂のフェライトに対する重量比を２以上にするなどして、搾乳口を介した***への接触温度を約４６℃に抑えればよい（４６℃は３０分程度は皮膚に接触させ続けても低温火傷にならない温度であり、通常、片胸約１０分程度を要する搾乳時間の安全率を見て長い搾乳時間であったとしても、低温火傷を有効に防止できる温度である）。しかし、より積極的に搾乳を促すには、単に低温火傷を防止するだけではなく、使用者に心地良さを与えることが好ましい。そこで、実験の結果、上記構成であれば、適切に加熱した搾乳用加温具を一般的なポリプロピレン製などの搾乳口の外周面に密着するように配置した際、搾乳口の***が接触する内周面側の温度を略３７〜４２℃にできることが分かった。この３７℃は通常の体温よりも若干高めの温度であり、また、４２℃は入浴時の少し高めの湯温であるため、この範囲内の接触温度であれば、単に低温火傷を防止するだけではなく、心地良さを使用者に与えることができる。従って、搾乳を効果的に促進することができる。 Preferably, the covering portion is made of a silicone resin, and a dimension in a thickness direction from the heat generating portion to the surface on the outer peripheral surface side is about 1 to 2 mm. Is a plate-like body having a thickness of about 0.5 to 1 mm, and the weight ratio of the silicone resin and the ferrite constituting the heat generating portion is about 6: 1 to 9: 1. .
With such a configuration, effective heating can be performed quickly by a microwave oven (for example, around 60 seconds for a 500 W microwave oven), and the contact temperature to the breast via the milking mouth is made comfortable. Can promote the delivery of breast milk.
That is, if only low-temperature burns of the breast are to be prevented, for example, the weight ratio of the silicone resin in the heat generating part to ferrite is set to 2 or more, so that the contact temperature to the breast through the milking mouth is suppressed to about 46 ° C. (46 ° C is a temperature that does not cause low-temperature burns even if it is kept in contact with the skin for about 30 minutes, and it is usually a long milking time in view of the safety factor of the milking time that requires about 10 minutes for one chest. Even so, it is a temperature that can effectively prevent low-temperature burns). However, in order to promote milking more positively, it is preferable not only to prevent low-temperature burns but also to give comfort to the user. Thus, as a result of the experiment, if the heating device is appropriately heated, the breast of the milking mouth comes into contact with the appropriately heated milking heating tool so as to be in close contact with the outer peripheral surface of the milking mouth made of general polypropylene or the like. It has been found that the temperature on the inner peripheral surface side can be approximately 37 to 42 ° C. This 37 ° C. is slightly higher than the normal body temperature, and 42 ° C. is a slightly higher hot water temperature at the time of bathing, so if the contact temperature is within this range, only low-temperature burns are prevented. Rather, it can give comfort to the user. Therefore, milking can be promoted effectively.

また、好ましくは、前記被覆部は、前記搾乳口を有する略漏斗状のフード部の搾乳器本体に着脱される筒状部が挿通可能な貫通孔と、前記貫通孔から外側に拡がった拡張部とを有し、前記拡張部は、前記搾乳口の外周面に対応した形状とされていることを特徴とする。
このため、フード部を搾乳器本体から取り外し、フード部の筒状部を搾乳用加温具の貫通孔に通したり、貫通孔から外したりして、搾乳用加温具を搾乳口に着脱可能に接続することができる。従って、フード部とは別に搾乳用加温具を単独で電子レンジで加熱することができ、フード部（搾乳口を含む）の電子レンジで加熱することによる変形・溶融の恐れを防止できる。
また、貫通孔から外側に拡がった拡張部は、搾乳口の外周面に対応した形状なので、搾乳口が可撓性の低い樹脂から形成されていても、拡張部を搾乳口の外周面に密着させることができる。 Preferably, the covering portion includes a through-hole through which a cylindrical portion that is attached to and detached from the breast pump main body of the substantially funnel-shaped hood portion having the milking mouth can be inserted, and an extended portion that extends outward from the through-hole. And the extended portion has a shape corresponding to the outer peripheral surface of the milking mouth.
For this reason, the hood part can be removed from the breast pump body, and the tubular part of the hood part can be passed through the through hole of the milking warming tool, or removed from the through hole, so that the milking heating tool can be attached to and detached from the milking mouth. Can be connected to. Accordingly, the milking heating tool can be independently heated in the microwave oven separately from the hood portion, and the risk of deformation and melting due to heating in the microwave oven of the hood portion (including the milking mouth) can be prevented.
In addition, since the extended portion extending outward from the through hole has a shape corresponding to the outer peripheral surface of the milking mouth, the extended portion is in close contact with the outer peripheral surface of the milking mouth even if the milking mouth is formed of a resin having low flexibility. Can be made.

また、好ましくは、前記搾乳口の外周面には、前記被覆部と係止して位置決めするための位置決め手段が形成されていることを特徴とする。
従って、搾乳用加温具が搾乳口に着脱される構造であっても、搾乳用加温具が搾乳口から外れてしまう恐れを有効に防止できる。 Preferably, positioning means for locking and positioning with the covering portion is formed on the outer peripheral surface of the milking mouth.
Therefore, even if it is the structure where the heating tool for milking is attached to or removed from the milking mouth, the possibility that the heating tool for milking may come off from the milking mouth can be effectively prevented.

また、好ましくは、前記拡張部は、前記搾乳口の略ラッパ状の周方向に沿って配置され、かつ、前記周方向の一部が途切れていることを特徴とする。
即ち、拡張部は貫通孔から一部の周縁部（貫通孔と反対側の開口部の周縁部）までが切り欠き部とされており、そうすると、拡張部はこの途切れた切り欠き部分を拡げるようにして周方向の寸法を変化させることができる。従って、搾乳用加温具は、それを接続するフード部が大きくても、周方向の寸法を変化させて接続することができる。 Preferably, the extended portion is arranged along a substantially trumpet-shaped circumferential direction of the milking mouth, and a part of the circumferential direction is interrupted.
That is, the extended portion has a notch from the through hole to a part of the peripheral edge (periphery of the opening opposite to the through hole), so that the extended portion expands the interrupted notch. Thus, the circumferential dimension can be changed. Therefore, even if the hood part which connects it is large, the heating tool for milking can be connected by changing the dimension of the circumferential direction.

また、好ましくは、前記被覆部は、弾性体であって、前記搾乳口の内周面に配置されることを特徴とする。
そうすると、授乳時に搾乳口に挿し入れた***と搾乳口の内周面に配置された被覆部とは直接的に接触することになる。
ここで、上述したように搾乳用加温具は低温火傷を防止するように***に接触する構成であるため、被覆部の厚みは所定の大きさを有している。そして、この厚みのある被覆部は弾性体であるため、搾乳時に***が搾乳器に吸い込まれた際、被覆部がクッションになって、痛みを和らげることができる。また、搾乳口の形状と***の形状が多少合致していなくても、***と被覆部とを密着させて乳首周辺の空間を負圧にし、確実に搾乳を行うことができる。 Moreover, Preferably, the said coating | coated part is an elastic body, Comprising: It arrange | positions at the internal peripheral surface of the said milking mouth, It is characterized by the above-mentioned.
When it does so, the breast inserted in the milking mouth at the time of breastfeeding and the covering part arranged on the inner peripheral surface of the milking mouth will be in direct contact.
Here, as described above, since the milking warming device is configured to contact the breast so as to prevent low-temperature burns, the thickness of the covering portion has a predetermined size. And since this thick coating | coated part is an elastic body, when a breast is suck | inhaled by the breast pump at the time of milking, a coating | coated part becomes a cushion and can relieve pain. Further, even if the shape of the milking mouth and the shape of the breast do not match somewhat, the breast and the covering portion are brought into close contact with each other, and the space around the nipple is made negative pressure, so that milking can be performed reliably.

そして、上記課題は、上述したいずれかに記載の搾乳用加温具が接続された前記搾乳口と、前記搾乳口で囲まれた空間を負圧にするための搾乳器本体とを有する搾乳器により解決される。
この構成によれば、上述したように、発熱部はフェライトを有しているので、電子レンジで短時間に加熱でき、しかも、搾乳時間中は温度が大きく低下する事態も防止できる。
また、発熱部の温度が高くても、被覆部が熱的に緩衝材になって、***の低温火傷を防止でき、少なくとも搾乳口を***にあてがった際のヒヤッと感から生じる緊張を回避して、ホルモン分泌の減少を防止することもできる。
しかも、この被覆部は熱硬化性の樹脂であるため、変形・溶融することなく、接続される搾乳口に合った適切な形状を保持できる。 And the said subject is a milking machine which has the said milking opening to which the heating tool for milking in any one mentioned above was connected, and the breast pump main body for making the space enclosed by the said milking opening into a negative pressure. It is solved by.
According to this configuration, as described above, since the heat generating portion has ferrite, it can be heated in a short time in a microwave oven, and a situation in which the temperature greatly decreases during the milking time can also be prevented.

FIG. 1 is a schematic central longitudinal sectional view of a milking warming device 10 according to a first embodiment of the present invention and a milking machine 20 using the same. In addition, about the part of the food | hood part 16 and the heating tool 10 for milking, the parallel oblique line showing a cross section is abbreviate | omitted and illustrated.
First, the milking machine 20 will be described.
The breast pump 20 in FIG. 1 is used when it is difficult to feed breast milk directly to an infant, when the nipple is damaged, when preventing mastitis, and the like, and a manual type is shown as an example of the present invention.
This manual milking machine 20 is an instrument that can be manually operated by a user, and can be operated by the user, so that it is lightweight and can be operated with one hand to reduce fatigue. Those are preferred.
The breast pump 20 in FIG. 1 includes a “hood part 16” applied to the breast, a “milker body 21” having a communication part S3 that is a space communicated with the space S1 surrounded by the hood part 16, and the main body 21. A "diaphragm 30" that is a negative pressure generating member that generates a negative pressure in the communication portion S3, a "handle 61" that is an operation portion that deforms the diaphragm 30, and a "bottle 11" for storing milked milk. ing.
Although the food | hood part 16, the diaphragm 30, the handle | steering_wheel 61, and the bottle 11 of this embodiment are detachable with respect to the breast pump main body 21 as a preferable aspect, this invention is not necessarily restricted to this, The main body 21 is attached. It may be fixed to.

「フード部１６」はファネル、或いはブレストキャップ等とも言い、比較的軽く、かつ、硬質な合成樹脂材料により成形され、変形し難くなっており、例えば熱可塑性部材であるポリプロピレンからなるのが一般的である。
フード部１６は、全体的には漏斗状とされており、搾乳時に***を覆う略ラッパ状・略ドーム状の搾乳口１８と、この搾乳口１８の最も径の小さい縮径部１８Ａから延伸して搾乳器本体２１に着脱可能に接続される筒状部１９を有している。 The “hood portion 16” is also called a funnel or a breast cap, and is formed of a relatively light and hard synthetic resin material and hardly deformed. For example, it is generally made of polypropylene which is a thermoplastic member. It is.
The hood portion 16 is generally funnel-shaped and extends from a substantially trumpet-shaped or substantially dome-shaped milking port 18 that covers the breast during milking and a reduced diameter portion 18A having the smallest diameter of the milking port 18. And has a cylindrical part 19 that is detachably connected to the breast pump main body 21.

搾乳口１８は、***が挿入される部分であり、***に対応した形状を有する内周面１８Ｂに囲まれた空間Ｓ１を有している。そして、最も径の大きい拡径部１８Ｃから***が挿し入れられ、空間Ｓ１に***が収まって、内周面１８Ｂに***が略密着し、これにより縮径部１８Ａ付近に配置された乳首周辺が密閉空間とされる。図の搾乳器２０の場合、この乳首周辺の密閉空間を負圧にすることで搾乳する構造となっている。なお、搾乳口１８は透明又は半透明である。
筒状部１９は、搾乳口１８の略中心線ＣＬに沿って延伸しており、搾乳口１８側と反対側の端部１９Ａが搾乳器本体２１に挿入され、搾乳器本体２１から搾乳時には抜けないように嵌合されている。本実施形態の筒状部１９は略円筒体とされているが、本発明はこれに限られるものではなく、例えば、正三角形体、正四角形体、正多角形体等であってもよい。 The milking mouth 18 is a portion into which a breast is inserted, and has a space S1 surrounded by an inner peripheral surface 18B having a shape corresponding to the breast. Then, the breast is inserted from the enlarged diameter portion 18C having the largest diameter, the breast is accommodated in the space S1, and the breast is substantially in close contact with the inner peripheral surface 18B, whereby the nipple area disposed near the reduced diameter portion 18A is It is a sealed space. In the case of the milking machine 20 in the figure, the structure is such that milking is performed by making the sealed space around the nipple negative pressure. The milking mouth 18 is transparent or translucent.
The cylindrical portion 19 extends along a substantially center line CL of the milking mouth 18, and an end 19 </ b> A opposite to the milking mouth 18 side is inserted into the breast pump main body 21, and comes off from the breast pump main body 21 during milking. It is not fitted. Although the cylindrical part 19 of this embodiment is made into a substantially cylindrical body, this invention is not limited to this, For example, a regular triangle body, a regular square body, a regular polygon body, etc. may be sufficient.

「搾乳器本体２１」は、比較的軽く、かつ、硬質な合成樹脂材料により成形されており、例えば、ポリプロピレン、ポリカーボネート、ポリシクロオレフィン、ポリエーテルサルフォン、ポリフェニルサルフォン等により形成されている。
搾乳器本体２１のフード部１６が装着される装着部１７は筒状であって、その内側に通気及び搾乳した母乳の通路とされる通気路２３を有している。通気路２３は、本体２１内の略中央部に形成された内部空間Ｓ２を介して、連通部Ｓ３と空間的に繋がっている。
連通部Ｓ３は負圧が付与される領域であり、この連通部Ｓ３を覆って封止するようにダイヤフラム３０が接続されている。そして、ダイヤフラム３０の変形により連通部Ｓ３を負圧状態にすると、内部空間Ｓ２と通気路２３を介して、フード部１６で囲まれた空間Ｓ１を負圧にすることができる。 The “milker body 21” is formed of a relatively light and hard synthetic resin material, and is formed of, for example, polypropylene, polycarbonate, polycycloolefin, polyethersulfone, polyphenylsulfone, or the like. .
The mounting portion 17 to which the hood portion 16 of the breast pump main body 21 is attached has a cylindrical shape, and has an air passage 23 serving as a passage for the aerated and milked breast milk. The air passage 23 is spatially connected to the communication portion S3 via an internal space S2 formed at a substantially central portion in the main body 21.
The communication portion S3 is a region where a negative pressure is applied, and the diaphragm 30 is connected so as to cover and seal the communication portion S3. When the communication portion S3 is brought into a negative pressure state by the deformation of the diaphragm 30, the space S1 surrounded by the hood portion 16 can be made negative pressure via the internal space S2 and the air passage 23.

本体２１の内部空間Ｓ２の下側はボトル１１に向かって開口しており、この開口した部分に弁２６が設けられている。弁２６はシリコーンゴム等の弾性体で形成され、先端にスリット２６ａを有している。スリット２６ａは、連通部Ｓ３を負圧状態にすると閉じ、負圧状態から解放すると開くようになっている。これにより、連通部Ｓ３を負圧状態にすると母乳を内部空間Ｓ２に引き込み、該負圧状態を解放するとスリット２６ａが開いて、内部空間Ｓ２にある母乳をボトル１１に落とすことができる。   A lower side of the internal space S2 of the main body 21 opens toward the bottle 11, and a valve 26 is provided in the opened portion. The valve 26 is formed of an elastic body such as silicone rubber and has a slit 26a at the tip. The slit 26a is closed when the communicating portion S3 is in a negative pressure state, and is opened when the communication portion S3 is released from the negative pressure state. Thereby, when the communicating part S3 is brought into a negative pressure state, the breast milk is drawn into the internal space S2, and when the negative pressure state is released, the slit 26a is opened, and the breast milk in the internal space S2 can be dropped into the bottle 11.

本体２１の上部において、フード部１６と反対の位置には、アーム４８が延びている。このアーム４８の上端部には、ハンドル６１を取り付けるための支軸部４９が形成されている。
これにより、ハンドル６１は、本体２１の支軸部４９を中心に支軸部４９回り（図のＹ方向）に回動自在となり、この回動操作によりダイヤフラムは変形するようになっている。 In the upper part of the main body 21, an arm 48 extends at a position opposite to the hood part 16. A support shaft 49 for attaching the handle 61 is formed at the upper end of the arm 48.
As a result, the handle 61 is rotatable about the support shaft portion 49 of the main body 21 around the support shaft portion 49 (Y direction in the figure), and the diaphragm is deformed by this rotation operation.

「ダイヤフラム３０」は、負圧を発生させるための負圧発生部材であり、ハンドル６１の操作の作用を受けて変形し、連通部Ｓ３の空間の容積を変更することで、一定量の負圧を付与するようになっている。具体的には、ダイヤフラム３０はハンドル６１と結合部７０を介して連結されている。結合部７０は上方に突出し、例えばポリプロピレン、ポリカーボネート等の硬い合成樹脂で形成されている。なお、ダイヤフラム３０は、全体が比較的弾性に富んだ柔軟な変形材料、例えばシリコーンゴム、イソプレンゴム等により形成されている。   The “diaphragm 30” is a negative pressure generating member for generating a negative pressure. The diaphragm 30 is deformed in response to the operation of the handle 61 and changes the volume of the space of the communication portion S3. Is supposed to be granted. Specifically, the diaphragm 30 is connected to the handle 61 via the coupling portion 70. The coupling portion 70 protrudes upward and is made of a hard synthetic resin such as polypropylene or polycarbonate. The diaphragm 30 is made of a flexible deformable material, such as silicone rubber or isoprene rubber, which is relatively elastic as a whole.

「ハンドル６１」は長尺の形状であり、比較的硬質であって軽量な合成樹脂、例えば、ポリプロピレン、ポリカーボネート、ポリシクロオレフィン、ポリエーテルサルフォン等で成形されている。
ハンドル６１は、ダイヤフラム３０の上方に配置されて、結合部７０と連結してダイヤフラム３０を持ち上げるリフト部６１Ａと、このリフト部６１Ａから曲折して搾乳器本体２１の側面に対応して位置するレバー部６１Ｂとを有する。
レバー部６１Ｂの外面側にそえた指ＦＧを本体２１に接近するように動かすことで、ハンドル６１が支軸部４９を中心に回動し、リフト部６１Ａが結合部７０を介してダイヤフラム３０を上に持ち上げ、これにより連通部Ｓ３の空間が大きくなって負圧状態となり、母乳が吸われる。これに対し、指ＦＧの力を弱めると、ダイヤフラム３０の弾性力が発揮して、ダイヤフラム３０は元の状態に復帰し、連通部Ｓ３の負圧状態が解消されると共に弁２６が開いて、吸った母乳はボトルに落ちる。 The “handle 61” has a long shape and is formed of a relatively hard and lightweight synthetic resin such as polypropylene, polycarbonate, polycycloolefin, polyethersulfone, or the like.
The handle 61 is disposed above the diaphragm 30 and is connected to the coupling portion 70 to lift the diaphragm 30. The lever 61 is bent from the lift portion 61A and is positioned corresponding to the side surface of the breast pump main body 21. Part 61B.
By moving the finger FG arranged on the outer surface side of the lever portion 61B so as to approach the main body 21, the handle 61 rotates about the support shaft portion 49, and the lift portion 61A moves the diaphragm 30 via the coupling portion 70. Lifting up, the space of the communication portion S3 becomes large and a negative pressure state is obtained, and the breast milk is sucked. On the other hand, when the force of the finger FG is weakened, the elastic force of the diaphragm 30 is exerted, the diaphragm 30 returns to the original state, the negative pressure state of the communication portion S3 is canceled, and the valve 26 is opened. The sucked breast milk falls into the bottle.

「ボトル１１」は、その瓶口の周囲に形成された雄ネジ部（不図示）を有し、搾乳器本体２１の下部内面に形成された雌ネジ部（不図示）と螺合されることで着脱可能になっている。尚、ボトル１１は、搾乳器２０の専用品でもよいし、上述した着脱構造に適合した哺乳瓶等を利用してもよく、また、成形された容器ではなく、袋状とされていてもよい。   The “bottle 11” has a male screw portion (not shown) formed around the bottle mouth, and is screwed with a female screw portion (not shown) formed on the lower inner surface of the breast pump main body 21. It is detachable with. The bottle 11 may be a dedicated product for the breast pump 20, a baby bottle adapted to the above-described attachment / detachment structure, etc. may be used, and may be a bag shape instead of a molded container. .

ここで、上述した搾乳口１８には、搾乳口１８よりも高い温度で発熱して、搾乳口１８を加温するための発熱部１５を備えた搾乳用加温具１０が接続されている。
以下、この搾乳用加温具１０について、上述した図１と、図２〜図５を用いて説明する。
図２は、搾乳用加温具１０の斜視図、図３は搾乳用加温具１０を接続した状態のフード部１６の外周面（***が挿入される内側とは反対側の面）１８Ｄ側の斜視図、図４は搾乳用加温具１０とフード部１６の分解斜視図、図５は搾乳用加温具１０が接続されたフード部１６の斜視図であり、搾乳用加温具１０の一部が切り欠かれた図である。なお、図５の円で囲った図は、搾乳用加温具１０の切り欠かれた断面付近を拡大した図である。 Here, the milking mouth 18 described above is connected to the milking warming device 10 including a heat generating portion 15 that generates heat at a temperature higher than that of the milking mouth 18 and heats the milking mouth 18.
Hereinafter, this heating device 10 for milking is demonstrated using FIG. 1 mentioned above, and FIGS.
FIG. 2 is a perspective view of the milking warming device 10, and FIG. 3 is an outer peripheral surface (surface opposite to the inside where the breast is inserted) 18D side of the hood portion 16 in a state where the milking warming device 10 is connected. 4 is an exploded perspective view of the milking warming tool 10 and the hood part 16, and FIG. 5 is a perspective view of the hood part 16 to which the milking warming tool 10 is connected. It is the figure where a part of was cut away. In addition, the figure enclosed with the circle | round | yen of FIG. 5 is the figure which expanded the cross-section vicinity of the heating tool 10 for milking.

搾乳用加温具１０は、本実施形態の場合、搾乳口１８の外周面１８Ｄに配置され、搾乳口１８を介して***にその発熱温度を伝達するものであり、発熱部１５、及び、発熱部１５を被覆する被覆部１２を有している。
発熱部１５は、マイクロ波エネルギーを吸収して発熱するフェライト（Ｆｅ２Ｏ４）が配合されている。フェライトはＭｇＣｕＺｎ系のフェライトであり、例えばスピネル型構造を有している。そして、発熱部１５は、粉末状のＭｇＣｕＺｎ系フェライトをベース材となるシリコーン樹脂に添加して混練し、これを焼成することで形成されている。シリコーン樹脂とフェライトの重量比は、シリコーン樹脂：フェライトを約２：１〜９：１とするのが適当であり、好ましくは約６：１〜９：１である。この点については、後で測定試験の結果を用いて詳細に説明する。 In the case of the present embodiment, the milking warming device 10 is disposed on the outer peripheral surface 18D of the milking mouth 18, and transmits the heat generation temperature to the breast via the milking mouth 18, and the heating portion 15 and the heat generation. A covering portion 12 that covers the portion 15 is provided.
The heat generating part 15 is blended with ferrite (Fe 2 O 4 ) that absorbs microwave energy and generates heat. The ferrite is MgCuZn-based ferrite and has, for example, a spinel structure. The heat generating portion 15 is formed by adding powdered MgCuZn-based ferrite to a silicone resin as a base material, kneading, and firing the resultant. The weight ratio of silicone resin to ferrite is suitably about 2: 1 to 9: 1 of silicone resin: ferrite, and preferably about 6: 1 to 9: 1. This point will be described later in detail using the results of the measurement test.

このフェライト配合シリコーン樹脂からなる発熱部１５は、薄い板状体（シート体）をリング状にして形成され、図５に示す厚みＤ２は約０．５〜３ｍｍが可能であり、好ましくは約０．５〜１.０ｍｍにするとよい。このように発熱部１５は厚み寸法が小さく、かつ、フェライトを軟質性のシリコーン樹脂に配合していることから、所定の弾力性及び可撓性を有している。このため、発熱部１５は、力を加えない状態では概ね平らなリング状であるが、被覆部１２にカバーされた際は可撓して略円錐筒状となる（この円錐筒の形状は被覆部１２で保持される）。円錐筒状の発熱部１５は、被覆部１２を介して搾乳口１８の外周面１８Ｄに配置された際に、外周面１８Ｄに収まる寸法であり、図の場合、幅Ｗ１は約１５ｍｍ、円周の長さは概ね２５０ｍｍである。以上のサイズの発熱部１５であれば、重量が左程大きくなることもなく、搾乳器を持つ腕への負担もそれ程増すわけではない。   The heat generating portion 15 made of this ferrite-containing silicone resin is formed by forming a thin plate (sheet) into a ring shape, and the thickness D2 shown in FIG. 5 can be about 0.5 to 3 mm, preferably about 0. .5 to 1.0 mm is recommended. Thus, since the heat generating part 15 has a small thickness dimension and blends ferrite with a soft silicone resin, it has predetermined elasticity and flexibility. For this reason, the heat generating portion 15 has a generally flat ring shape when no force is applied, but when it is covered by the covering portion 12, it is flexible and becomes a substantially conical cylinder shape (the shape of this conical cylinder is the covering shape). Part 12). The conical cylinder-shaped heat generating portion 15 has a size that fits on the outer peripheral surface 18D when arranged on the outer peripheral surface 18D of the milking mouth 18 via the covering portion 12, and in the case of the figure, the width W1 is about 15 mm, the circumference The length of is approximately 250 mm. With the heat generating portion 15 having the above size, the weight does not increase as much as the left, and the burden on the arm having the breast pump does not increase so much.

被覆部１２は、発熱部１５が露出しないように発熱部１５の全体を覆って、発熱部１５から***に伝達される温度を低下させる緩衝材である。即ち、発熱部１５は電子レンジでマイクロ波を浴びると、かなり高温になり易くなっている（シリコーンとフェライトの配合比率にもよるが、通常の配合比率では１００度までは直ぐに上がってしまう）。このため、発熱部１５を覆う被覆部１２は、搾乳時に搾乳用加温具１０を付けた搾乳口１８の***への接触温度（図１の搾乳口１８の内周面１８Ｂの温度であり、好ましくは***への最初の接触温度）が、***の温度以上であって、かつ、***が火傷をしない温度となるように、その材料や厚みを工夫している。
さらに、搾乳には相当な時間を要し、個人差はあるものの片胸でも１０分程度を要することが多いことから、被覆部１２は、搾乳口１８が***に長時間接触することで生じる低温火傷を防止する構成とするが好ましい。この際、低温火傷は４６度では接触時間が３０分で起こる場合があることから、安全率をみて、***に接触している最中の接触温度は４６℃以下とするのがよい。 The covering portion 12 is a cushioning material that covers the entire heat generating portion 15 so that the heat generating portion 15 is not exposed and reduces the temperature transmitted from the heat generating portion 15 to the breast. That is, the heat generating part 15 is likely to be heated to a high temperature when exposed to microwaves in a microwave oven (although depending on the blending ratio of silicone and ferrite, it increases immediately up to 100 degrees at a normal blending ratio). For this reason, the coating | coated part 12 which covers the heat generating part 15 is the temperature to the breast of the milking mouth 18 which attached the heating tool 10 for milking at the time of milking (it is the temperature of the internal peripheral surface 18B of the milking mouth 18 of FIG. The material and thickness are devised so that the temperature of the first contact with the breast is preferably equal to or higher than the temperature of the breast and the breast does not burn.
Furthermore, milking takes a considerable amount of time, and although there are individual differences, it often takes about 10 minutes even for one breast, so that the covering portion 12 has a low temperature caused by the milking mouth 18 coming into contact with the breast for a long time. A structure that prevents burns is preferable. At this time, since the low temperature burn may occur in 46 minutes at a contact time of 30 minutes, the contact temperature during the contact with the breast is preferably 46 ° C. or less in view of the safety factor.

本実施形態の場合、被覆部１２は発熱部１５とは別体に形成され、熱伝導率が比較的低く、耐熱性の高いシリコーン樹脂で形成されている。即ち、発熱部１５のベース材となるシリコーン樹脂とは別に、更にシリコーン樹脂で発熱部１５を覆うことで、フェライトが存在しない所定の厚みを有する断熱層を形成し、これにより高温になり過ぎる発熱部１５の温度を下げている。なお、被覆部１２のシリコーン樹脂は、ミラブル型シリコーンと液状シリコーンのいずれであってもよい。   In the case of the present embodiment, the covering portion 12 is formed separately from the heat generating portion 15, and is formed of a silicone resin having a relatively low thermal conductivity and high heat resistance. That is, apart from the silicone resin that serves as the base material of the heat generating portion 15, the heat generating portion 15 is further covered with a silicone resin to form a heat insulating layer having a predetermined thickness where no ferrite is present. The temperature of the part 15 is lowered. Note that the silicone resin of the covering portion 12 may be either millable silicone or liquid silicone.

また、被覆部１２のシリコーン樹脂は、耐熱性に優れた熱硬化性樹脂であり、このため、電子レンジに入れて、その内側の発熱部１５が加熱しても変形・溶融することを防止できる。
図５に示すシリコーン樹脂からなる被覆部１２は、発熱部１５から搾乳口の外周面１８Ｄ側の面（内側面）１２Ｄまでの厚みＤ１として０．５〜３ｍｍが可能であり、好ましくは１〜２ｍｍにするとよい。これにより、搾乳用加温具１０の搾乳口１８を介した***への接触温度を、***の温度以上であって、かつ、少なくとも低温火傷をしない温度以下とすることができ、更には、使用者にとって心地の良い温度とすることができる。 In addition, the silicone resin of the covering portion 12 is a thermosetting resin excellent in heat resistance, and therefore, it can be prevented from being deformed / melted even if it is placed in a microwave oven and the heat generating portion 15 inside thereof is heated. .
The covering portion 12 made of the silicone resin shown in FIG. 5 can have a thickness D1 from the heat generating portion 15 to the outer peripheral surface 18D side surface (inner surface) 12D of the milking mouth of 0.5 to 3 mm, preferably 1 to 1 mm. It should be 2 mm. Thereby, the contact temperature to the breast through the milking opening 18 of the heating tool 10 for milking can be made to be not less than the temperature of the breast and at least not to a temperature at which low-temperature burns are not caused. The temperature can be comfortable for a person.

また、被覆部１２は、搾乳口１８と反対側の表面１２Ｅの温度を、***への接触温度と同等以上であって、かつ、適正に発熱した搾乳用加温具１０を手で触った際に低温火傷をしない温度以下となるようにしている。従って、加熱した搾乳用加温具１０の温度を搾乳前に手で容易に感じられるようにして、過熱した搾乳用加温具１０の搾乳口１８への装着を躊躇させて、***の火傷を未然に防止できる。また、被覆部１２の該表面１２Ｅの温度は、搾乳用加温具１０を搾乳口１８に装着する際に低温火傷をしない温度以下となり、搾乳用加温具１０が着脱式であっても、手を火傷することなくフード部１６に装着できる。
図の場合、発熱部１５は、被覆部１２の厚み方向の中央部に配置されており、発熱部１５から被覆部１２の該表面１２Ｅまでの厚みＤ３を厚みＤ１と同様にし、適正に発熱した搾乳用加温具１０の該表面１２Ｅの温度を凡そ５０〜５３℃としている。該表面温度が５０〜５３℃であれば、十分、手で熱を感じて危険の察知が可能である。また、概ね２分間、該表面１２Ｅを直接手で触り続けても低温火傷することはなく、２分間あれば搾乳用加温具１０をフード部１６に装着可能である。 Moreover, the coating | coated part 12 is when the temperature of the surface 12E on the opposite side to the milking opening 18 is equal to or higher than the contact temperature to the breast, and the milking warming device 10 that has appropriately heated is touched by hand. The temperature is set so as not to cause low temperature burns. Accordingly, the temperature of the heated milking heating tool 10 can be easily felt by hand before milking, and the overheating of the heating milking heating tool 10 is made to be attached to the milking mouth 18 so that the breast burns. It can be prevented beforehand. In addition, the temperature of the surface 12E of the covering portion 12 is equal to or lower than a temperature at which low temperature burns are not caused when the milking warming tool 10 is attached to the milking mouth 18, and the milking warming tool 10 is removable. It can be attached to the hood 16 without burning the hand.
In the case of the figure, the heat generating portion 15 is disposed at the center in the thickness direction of the covering portion 12, and the thickness D3 from the heat generating portion 15 to the surface 12E of the covering portion 12 is made the same as the thickness D1, and heat is appropriately generated. The temperature of the surface 12E of the heating tool 10 for milking is about 50 to 53 ° C. If the surface temperature is 50 to 53 ° C., it is possible to detect danger by feeling heat by hand. Further, even if the surface 12E is kept in direct contact with the hand for approximately 2 minutes, there is no low-temperature burn, and the warming tool 10 for milking can be attached to the hood 16 within 2 minutes.

なお、本実施形態では、発熱部１５と被覆部１２とは別体に形成され、これらを組み合わせて形成されているが、両者を一体化して構わない。例えば、図５の一点鎖線で囲った図に示すように、シリコーン樹脂にフェライト粉末を配置した発熱部２の層を中央部に形成し、その上下にフェライトが存在しないシリコーン樹脂からなる被覆部３の層を形成するようにして、発熱部２の全周を被覆部３で囲んでも構わない。   In the present embodiment, the heat generating portion 15 and the covering portion 12 are formed separately and combined to form them, but they may be integrated. For example, as shown in a diagram surrounded by a one-dot chain line in FIG. 5, a layer of a heat generating portion 2 in which ferrite powder is arranged on a silicone resin is formed in the central portion, and a covering portion 3 made of a silicone resin having no ferrite above and below it. The entire circumference of the heat generating part 2 may be surrounded by the covering part 3 so as to form the above layer.

図１〜図４に示すように、被覆部１２はそのまま搾乳用加温具１０の外形形状をなすものであり、被覆部１２の外形形状における特徴は搾乳用加温具１０の外形形状の特徴となる。
図の被覆部１２の外形形状は、搾乳口１８の外周面１８Ｄに対応して、全体として円錐筒型・ドーム型をしたリング状とされている。即ち、被覆部１２は、フード部１６の筒状部１９が挿通可能な貫通孔８を中央部に有している。貫通孔８は筒状部１９の外径よりも僅かに大きな円形状であり、その直径Ｌは約５０ｍｍである。これにより、搾乳用加温具１０は、搾乳器本体２１から取り外したフード部１６に対して着脱可能となり、従って、ポリプロピレン等の熱可塑性であって熱により変形・溶融する恐れのあるフード部１６から取り外して、電子レンジで加熱することができる。 As shown in FIGS. 1-4, the coating | coated part 12 makes the outer shape of the heating tool 10 for milking as it is, The characteristic in the external shape of the coating | coated part 12 is the characteristic of the outer shape of the heating tool 10 for milking. It becomes.
The outer shape of the covering portion 12 in the figure corresponds to the outer peripheral surface 18 </ b> D of the milking mouth 18, and is a ring shape having a conical cylinder shape or a dome shape as a whole. That is, the covering portion 12 has a through hole 8 through which the cylindrical portion 19 of the hood portion 16 can be inserted in the center portion. The through hole 8 has a circular shape that is slightly larger than the outer diameter of the cylindrical portion 19, and its diameter L is about 50 mm. Thereby, the heating device 10 for milking becomes detachable with respect to the food | hood part 16 removed from the breast pump main body 21, Therefore, it is thermoplastics, such as a polypropylene, The food | hood part 16 which may deform | transform and melt | dissolve with heat. Can be removed and heated in a microwave oven.

また、図２及び図３に示すように、被覆部１２は、貫通孔８から外側に拡がった拡張部１２Ｂを有している。この拡張部１２Ｂが搾乳口１８に接続される部分であり、被覆部１２の外形形状をなし、本実施形態の場合、搾乳口１８の外周面１８Ｄに密着して配置可能なように、外周面１８Ｄに対応した円錐筒型・ドーム型をしたリング状とされている。
従って、被覆部１２は、拡張部１２Ｂが搾乳口１８の外周面１８Ｄに密着し、また、その材料であるシリコーン樹脂が弾性力を有しているため、グリップ力により搾乳口１８の外周面１８Ｄから位置ずれし難くなっている。 As shown in FIGS. 2 and 3, the covering portion 12 has an extended portion 12 </ b> B that extends outward from the through hole 8. The extended portion 12B is a portion connected to the milking mouth 18, and forms the outer shape of the covering portion 12. In the case of this embodiment, the outer peripheral surface is arranged so as to be in close contact with the outer peripheral surface 18D of the milking mouth 18. It is a ring shape with a conical cylinder shape and a dome shape corresponding to 18D.
Accordingly, in the covering portion 12, the expanded portion 12B is in close contact with the outer peripheral surface 18D of the milking mouth 18, and since the silicone resin that is the material has an elastic force, the outer peripheral surface 18D of the milking mouth 18 by the grip force. It is difficult to shift the position.

さらに、図３〜図５に示すように、搾乳口１８の外周面１８Ｄに対する拡張部１２Ｂの適正な配置を維持するため、外周面１８Ｄには、被覆部１２と係止して位置決めするための位置決め手段７７が設けられている。図の位置決め手段７７は、拡張部１２Ｂを搾乳口１８の外周面１８Ｄに配置した際の貫通孔８の縁８Ａの位置にあり、搾乳口１８の外周面１８Ｄから突出して形成されている。この突出度合い（位置決め手段７７の高さ）は、フード部１６の筒状部１９を貫通孔８に通してから、搾乳口１８の外周面１８Ｄに拡張部１２Ｂを配置する際、所定の可撓性を有する拡張部１２Ｂが乗り越えられる程度の低い高さである。
このように位置決め手段７７の高さが低くても、拡張部１２Ｂはシリコーン樹脂であって所定の弾性力を有することから、拡張部１２Ｂが位置決め手段７７を一旦乗り越えると、拡張部１２Ｂと位置決め手段７７とは係止されることになる。図の位置決め手段７７は同間隔で複数設けられ、夫々が貫通孔８の縁８Ａと同様に湾曲している。
なお、図２に示す拡張部１２Ｂは、貫通孔８と反対側の開口部１２Ｃの外縁部２４が、図１に示すように、搾乳口１８の拡径部１８Ｃ側に形成された凸部２９と係合する凹部２８を有し、これにより、搾乳時に搾乳用加温具１０が位置ずれする恐れをより効果的に防止しているが、位置決め手段７７があれば、この凸部２９と凹部２８の係合は必ずしも必要ではない。 Furthermore, as shown in FIGS. 3-5, in order to maintain the appropriate arrangement | positioning of the expansion part 12B with respect to outer peripheral surface 18D of the milking mouth 18, it is locked with the coating | coated part 12 and positioned on outer peripheral surface 18D. Positioning means 77 is provided. The positioning means 77 in the figure is located at the position of the edge 8A of the through hole 8 when the extended portion 12B is disposed on the outer peripheral surface 18D of the milking port 18, and is formed so as to protrude from the outer peripheral surface 18D of the milking port 18. This degree of protrusion (the height of the positioning means 77) is a predetermined flexibility when the extended portion 12B is disposed on the outer peripheral surface 18D of the milking port 18 after passing the cylindrical portion 19 of the hood portion 16 through the through hole 8. The height is low enough to allow the extended portion 12B to be overcome.
Thus, even if the positioning means 77 is low, the extension portion 12B is made of silicone resin and has a predetermined elastic force. Therefore, once the extension portion 12B gets over the positioning means 77, the extension portion 12B and the positioning means 12B. 77 is locked. A plurality of positioning means 77 shown in the figure are provided at the same interval, and each is bent similarly to the edge 8A of the through hole 8.
In addition, as for the extended part 12B shown in FIG. 2, the outer edge part 24 of the opening part 12C on the opposite side to the through-hole 8 has the convex part 29 formed in the diameter-expanded part 18C side of the milking port 18, as shown in FIG. , Thereby preventing the milking heating device 10 from being displaced more effectively at the time of milking. The engagement of 28 is not always necessary.

〔測定試験について〕
図６〜図１０は、上述した実施形態と同様、約１ｍｍの厚さを有するポリプロピレン製の搾乳口の外周面に搾乳用加温具を密着させて、搾乳口の内周面の温度（これが***への接触温度となる）等を測定した試験結果である（なお、以下の図６〜図１０の説明において記載する符号については、図５に示す符号を参照）。
この測定試験により、上述した被覆部１２の発熱部１５から搾乳口の外周面側の面（内側面）１２Ｄまでの厚み方向の寸法Ｄ１が略１〜２ｍｍ、発熱部１５がシリコーン樹脂にフェライトを配合した略０．５〜１ｍｍの厚みを有する板状体、発熱部１２のシリコーン樹脂とフェライトの重量比が略３：１〜９：１であるのが適当であり、更には、発熱部１５のシリコーン樹脂とフェライトの重量比が略６：１〜９：１であるのがより好ましいことが分かる。以下、図毎に説明する。 [About measurement test]
6 to 10, as in the above-described embodiment, a milking warming tool is brought into close contact with the outer peripheral surface of a milking mouth made of polypropylene having a thickness of about 1 mm, and the temperature of the inner peripheral surface of the milking mouth (this is (It is a contact temperature to the breast) and the like (for reference numerals shown in the following description of FIGS. 6 to 10, refer to the reference numerals shown in FIG. 5).
By this measurement test, the dimension D1 in the thickness direction from the heat generating portion 15 of the covering portion 12 to the outer peripheral surface side surface (inner surface) 12D of the milking mouth is approximately 1 to 2 mm, and the heat generating portion 15 applies ferrite to the silicone resin. It is appropriate that the weight ratio of the blended plate-like body having a thickness of about 0.5 to 1 mm, the silicone resin and the ferrite of the heat generating part 12 is about 3: 1 to 9: 1, and further, the heat generating part 15 It can be seen that it is more preferable that the weight ratio of the silicone resin to ferrite is approximately 6: 1 to 9: 1. Hereinafter, it demonstrates for every figure.

図６は、発熱部１５の厚さＤ２とフェライト配合比率の夫々を変えた場合の測定試験であり、図６（Ａ）はその測定条件、図６（Ｂ）はその試験結果（搾乳口の内周面の最高温度）である。
図６（Ａ）に示すように、測定試験は、被覆部１２の発熱部１５から内側面１２Ｄまでの寸法（以下、「被覆部１２の厚さ」という）Ｄ１が２ｍｍである搾乳用加温具を、出力５００Ｗの電子レンジで６０秒間加熱した。そうしたところ、図６（Ｂ）に示すように、発熱部１５の厚みＤ２が０．５〜１ｍｍの場合、発熱部１２のシリコーン樹脂とフェライトの重量比が３：１〜９：１の範囲において、搾乳口の内周面の温度を３７〜４２℃にすることができた。３７℃は通常の体温よりも若干高めの温度、４２℃は入浴時の少し高めの湯温であるため、この範囲内の接触温度であれば、単に低温火傷を防止するだけではなく、積極的に心地良さを使用者に与えて、搾乳を効果的に促進することができる。なお、単に低温火傷を防止するだけであれば、発熱部１５を構成するシリコーン樹脂とフェライトの重量比を約２：１にすることも可能である。 FIG. 6 is a measurement test when the thickness D2 of the heat generating part 15 and the ferrite blending ratio are changed, FIG. 6 (A) shows the measurement conditions, and FIG. 6 (B) shows the test result (milking mouth's result). Maximum temperature of the inner peripheral surface).
As shown in FIG. 6 (A), the measurement test is performed by heating for milking in which the dimension D1 from the heat generating portion 15 of the covering portion 12 to the inner side surface 12D (hereinafter referred to as “the thickness of the covering portion 12”) is 2 mm. The tool was heated in a microwave oven with an output of 500 W for 60 seconds. As shown in FIG. 6B, when the thickness D2 of the heat generating part 15 is 0.5 to 1 mm, the weight ratio of the silicone resin and the ferrite of the heat generating part 12 is in the range of 3: 1 to 9: 1. The temperature of the inner peripheral surface of the milking mouth could be 37-42 degreeC. 37 ° C is a slightly higher temperature than normal body temperature, and 42 ° C is a slightly higher hot water temperature at the time of bathing. Therefore, a contact temperature within this range not only prevents low-temperature burns but also actively The comfort can be given to the user and milking can be effectively promoted. If only low-temperature burns are to be prevented, the weight ratio of the silicone resin and ferrite constituting the heat generating portion 15 can be about 2: 1.

図７は電子レンジの出力と加熱時間を変えた場合の測定試験であり、図７（Ａ）はその測定条件、図７（Ｂ）は試験結果（搾乳口の内周面の最高温度）である。
図７から分かるように、発熱部１５の厚さＤ２が１ｍｍ、被覆部１２の厚さＤ１が２ｍｍ、発熱部１５のシリコーン樹脂とフェライトの重量比が６：１の搾乳用加温具について、電子レンジが出力５００Ｗであっても１０００Ｗであっても、加熱時間を対応させることで、搾乳口の内周面の温度を３７〜４２℃にすることができる。
なお、例えば、発熱部１５のシリコーン樹脂とフェライトの重量比について、図７の６：１から９：１に測定条件を変更した場合、図６に示すように１〜２℃温度ほど低下するので、加熱時間をその分増やせば、搾乳口の内周面の温度を３７〜４２℃にできることが分かる。該重量比を３：１に測定条件を変更した場合も、図６に示すように２〜３℃温度ほど上昇するので、加熱時間をその分減らせば、搾乳口の内周面の温度を３７〜４２℃にできることも分かる。
また、発熱部１５の厚さＤ２についても、図７の１ｍｍから０．５ｍｍに測定条件を変更した場合、図６に示すように、１ｍｍに比べて１〜２℃の低下があるため、その分、加熱時間を増やせば、搾乳口の内周面の温度を３７〜４２℃にできることも分かる。
また、被覆部１２の厚さＤ１についても、図７の２ｍｍから１ｍｍに測定条件を変更した場合、後述する図８に示すように、２℃ほど上昇するので、その分、加熱時間を減らせば、搾乳口の内周面の温度を３７〜４２℃にできることも分かる。
以上のように、電子レンジの出力値と加熱時間は、被覆部１２の厚さＤ１が略１〜２ｍｍ、発熱部１５の厚さＤ２が０．５〜１ｍｍ、発熱部１５のシリコーン樹脂とフェライトの重量比が３：１〜９：１の範囲内である場合、加熱時間を大きく変えることなく、搾乳口の内周面の温度を３７〜４２℃にできることが分かる。このように電子レンジの出力値と加熱時間は種々の条件により変更して決めることができるため、先ず、目標とする搾乳口の内周面の温度（***への接触温度）を決め、次に、発熱部１５の厚さＤ２、被覆部１２の厚さＤ１、及び発熱部１５のシリコーン樹脂とフェライトの重量比を特定し、最後に、これらの条件を満たすように使用者側の使用条件として電子レンジの出力値と加熱時間を決めればよい。 FIG. 7 is a measurement test when the output of the microwave oven and the heating time are changed, FIG. 7 (A) is the measurement condition, and FIG. 7 (B) is the test result (maximum temperature of the inner peripheral surface of the milking mouth). is there.
As can be seen from FIG. 7, the milking warming device in which the thickness D2 of the heat generating portion 15 is 1 mm, the thickness D1 of the covering portion 12 is 2 mm, and the weight ratio of the silicone resin and ferrite of the heat generating portion 15 is 6: 1. Regardless of whether the microwave oven has an output of 500 W or 1000 W, the temperature of the inner peripheral surface of the milking mouth can be set to 37 to 42 ° C. by making the heating time correspond.
For example, when the measurement condition is changed from 6: 1 to 9: 1 in FIG. 7 for the weight ratio of the silicone resin and ferrite in the heat generating part 15, the temperature decreases by 1 to 2 ° C. as shown in FIG. It can be seen that if the heating time is increased accordingly, the temperature of the inner peripheral surface of the milking mouth can be set to 37 to 42 ° C. Even when the measurement condition is changed to 3: 1, the temperature rises by 2 to 3 ° C. as shown in FIG. 6. Therefore, if the heating time is reduced by that amount, the temperature of the inner peripheral surface of the milking mouth is 37. It can also be seen that it can be -42 ° C.
In addition, as for the thickness D2 of the heat generating portion 15, when the measurement condition is changed from 1 mm to 0.5 mm in FIG. 7, there is a decrease of 1 to 2 ° C. compared to 1 mm as shown in FIG. It can also be seen that if the heating time is increased, the temperature of the inner peripheral surface of the milking mouth can be 37-42 ° C.
Also, with respect to the thickness D1 of the covering portion 12, when the measurement condition is changed from 2 mm to 1 mm in FIG. 7, the temperature rises by about 2 ° C. as shown in FIG. It can also be seen that the temperature of the inner peripheral surface of the milking mouth can be 37-42 ° C.
As described above, the output value and the heating time of the microwave oven are such that the thickness D1 of the covering portion 12 is about 1 to 2 mm, the thickness D2 of the heat generating portion 15 is 0.5 to 1 mm, and the silicone resin and ferrite of the heat generating portion 15 When the weight ratio is in the range of 3: 1 to 9: 1, it can be seen that the temperature of the inner peripheral surface of the milking mouth can be 37 to 42 ° C. without greatly changing the heating time. Thus, since the output value and heating time of the microwave oven can be changed and determined according to various conditions, first, the temperature of the inner peripheral surface of the milking mouth (contact temperature to the breast) is determined, and then Then, the thickness D2 of the heat generating part 15, the thickness D1 of the covering part 12, and the weight ratio of the silicone resin and the ferrite of the heat generating part 15 are specified, and finally the use conditions on the user side so as to satisfy these conditions What is necessary is just to decide the output value and heating time of a microwave oven.

図８は被覆部１２の厚さＤ１を変えた場合の測定試験であり、図８（Ａ）はその測定条件、図８（Ｂ）は試験結果（搾乳口の内周面の最高温度）である。
図８に示すように、発熱部１５のシリコーン樹脂とフェライトの重量比が６：１であって、発熱部１５の厚さＤ２が１ｍｍである場合には、被覆部１２の厚さＤ１が１〜２ｍｍの範囲内で、搾乳口の内周面の温度を４０〜４２℃とすることができた。
この点、発熱部１５のシリコーン樹脂とフェライトの重量比が９：１の場合は、６：１の時と比べて搾乳口の内周面の温度は低下（例えば、図６に示すように重量比が６：１の時と比べて１〜２℃低下）するので、該重量比が９：１の場合も、同様に被覆部１２の厚さＤ１が１〜２ｍｍの範囲内で、心地良さを与える３７〜４２℃の範囲内にできることが分かる。
しかし、該重量比が３：１の場合は、反対に搾乳口の内周面の温度は上昇するため、被覆部１２の厚さＤ１が１ｍｍの場合は、図８（Ｂ）に示す試験結果の４２℃を超えてしまうことが分かる。
従って、被覆部１２の厚さＤ１を１〜２ｍｍとする条件であれば、発熱部１５のシリコーン樹脂とフェライトの重量比は略６：１〜９：１とすることが、心地良さを与える観点からは好ましいことが分かる。
なお、単に低温火傷を防止するという観点の場合、搾乳口の内周面の温度は約４６℃以下であれば十分であり、図６と図８を併せて考慮すれば、被覆部１２の厚さＤ１を約１〜２ｍｍ、発熱部１５の厚さＤ２を約０．５〜１ｍｍ、発熱部１５のシリコーン樹脂とフェライトの重量比を約２：１（少なくとも３：１）〜９：１にすることで可能なことが分かる。 FIG. 8 is a measurement test when the thickness D1 of the covering portion 12 is changed, FIG. 8 (A) is the measurement condition, and FIG. 8 (B) is the test result (maximum temperature of the inner peripheral surface of the milking mouth). is there.
As shown in FIG. 8, when the weight ratio of the silicone resin and the ferrite in the heat generating portion 15 is 6: 1 and the thickness D2 of the heat generating portion 15 is 1 mm, the thickness D1 of the covering portion 12 is 1. Within the range of ˜2 mm, the temperature of the inner peripheral surface of the milking mouth could be 40 to 42 ° C.
In this respect, when the weight ratio of the silicone resin and the ferrite of the heat generating portion 15 is 9: 1, the temperature of the inner peripheral surface of the milking mouth is lower than when the weight ratio is 6: 1 (for example, as shown in FIG. The ratio is reduced by 1 to 2 ° C. compared to when the ratio is 6: 1. Therefore, even when the weight ratio is 9: 1, the thickness D1 of the covering portion 12 is similarly within the range of 1 to 2 mm. It turns out that it can be in the range of 37-42 degreeC which gives.
However, when the weight ratio is 3: 1, on the contrary, the temperature of the inner peripheral surface of the milking mouth rises. Therefore, when the thickness D1 of the covering portion 12 is 1 mm, the test result shown in FIG. It can be seen that the temperature exceeds 42 ° C.
Therefore, if the thickness D1 of the covering portion 12 is 1 to 2 mm, the weight ratio of the silicone resin and the ferrite of the heat generating portion 15 is approximately 6: 1 to 9: 1. It can be seen that it is preferable.
In the case of simply preventing low-temperature burns, it is sufficient if the temperature of the inner peripheral surface of the milking mouth is about 46 ° C. or less, and the thickness of the covering portion 12 is considered in combination with FIG. 6 and FIG. The thickness D1 is about 1-2 mm, the thickness D2 of the heat generating part 15 is about 0.5-1 mm, and the weight ratio of the silicone resin and ferrite of the heat generating part 15 is about 2: 1 (at least 3: 1) to 9: 1. You can see what is possible.

図９は被覆部１２の表面温度の測定試験であり、図９（Ａ）はその測定条件、図９（Ｂ）は試験結果（被覆部の表面温度の最高温度）である。
図９に示されるように、被覆部１２の厚さＤ１を２ｍｍ、発熱部１５の厚さＤ２を１ｍｍ、発熱部１５のシリコーン樹脂とフェライトの重量比を６：１にした場合、被覆部１２自体の表面温度は５３℃となる。
この点、５３℃は、約２分間、手で接触し続けて低温火傷する温度であり、２分間あれば、着脱可能な搾乳用加温具を搾乳口に接続できるので、低温火傷を防止することができる。また、該重量比が９：１の場合、被覆部１２自体の表面温度は５３℃を下回るため、同様に低温火傷を防止できることは分かる。しかし、フェライトに対するシリコーン樹脂の重量比が６を下回る場合は、場合によっては、低温火傷を防止可能な時間内で、搾乳用加温具を搾乳口に接続することが出来ないことが想定される。従って、この搾乳用加温具を搾乳口に接続するという点でも、発熱部１５のシリコーン樹脂とフェライトの重量比は略６：１〜９：１とすることがより好ましい。
なお、このように被覆部１２自体の表面温度は手で触れても、その温度を十分に感知できるため、過熱してしまった場合、使用者に搾乳用加温具の搾乳口への装着を躊躇させて、***の火傷を未然に防止することができる。 FIG. 9 shows a measurement test of the surface temperature of the covering portion 12, FIG. 9A shows the measurement conditions, and FIG. 9B shows the test result (maximum temperature of the surface temperature of the covering portion).
As shown in FIG. 9, when the thickness D1 of the covering portion 12 is 2 mm, the thickness D2 of the heat generating portion 15 is 1 mm, and the weight ratio of the silicone resin and ferrite of the heat generating portion 15 is 6: 1, the covering portion 12 The surface temperature of itself is 53 ° C.
In this respect, 53 ° C. is a temperature at which low temperature burns continue to be touched by hand for about 2 minutes, and if it is 2 minutes, a removable milking heating tool can be connected to the milking opening, thus preventing low temperature burns. be able to. In addition, when the weight ratio is 9: 1, it can be seen that the surface temperature of the covering portion 12 itself is less than 53 ° C., and thus low temperature burns can be similarly prevented. However, when the weight ratio of the silicone resin to the ferrite is less than 6, in some cases, it is assumed that the heating device for milking cannot be connected to the milking mouth within a time during which low temperature burns can be prevented. . Therefore, it is more preferable that the weight ratio of the silicone resin and the ferrite of the heat generating portion 15 is approximately 6: 1 to 9: 1 also in that the heating device for milking is connected to the milking mouth.
In addition, even if it touches the surface temperature of coating | coated part 12 itself in this way, since the temperature can fully be sensed, when it overheats, a user should mount | wear the milking mouth with the heating tool for milking. It can be let down to prevent breast burns.

図１０は、被覆部１２の厚さＤ１を２ｍｍ、発熱部１５の厚さＤ２を１ｍｍ、発熱部１５のシリコーン樹脂とフェライトの重量比を６：１にし、出力５００Ｗの電子レンジで６０秒間加熱した場合、搾乳用加温具を搾乳口に接続した前後の搾乳口の内周面の温度の推移データである。なお、図１０では、***を実際に搾乳口に当てて搾乳口の内周面の温度を測定している。また、図１０のＡ点は、搾乳口に加熱した搾乳用加温具を装着した時、Ｂ点は搾乳口を***に当てた時、Ｃ点は搾乳口を***から一時的に外した時、Ｄ点は搾乳口を再び***に当てた時、Ｅ点は搾乳を終えて搾乳口を***から外した時である。   FIG. 10 shows that the thickness D1 of the covering portion 12 is 2 mm, the thickness D2 of the heat generating portion 15 is 1 mm, the weight ratio of the silicone resin and ferrite of the heat generating portion 15 is 6: 1, and heating is performed for 60 seconds in a microwave oven with an output of 500 W. When it does, it is transition data of the temperature of the internal peripheral surface of the milking mouth before and after connecting the heating tool for milking to the milking mouth. In FIG. 10, the breast is actually applied to the milking mouth, and the temperature of the inner peripheral surface of the milking mouth is measured. In addition, point A in FIG. 10 is when a heated milking heater is attached to the milking mouth, point B is when the milking mouth is applied to the breast, and point C is when the milking mouth is temporarily removed from the breast. Point D is when the milking mouth is again applied to the breast, and point E is when milking is finished and the milking mouth is removed from the breast.

図１０に示すように、搾乳用加温具を搾乳口に装着する前の搾乳口の内周面の温度は約２５℃であったが、搾乳用加温具を加熱して約６０秒後に搾乳口の外周面に装着したＡ点から約９０秒後のＢ点（搾乳口を***に当てた時点であり、加熱後からは約１５０秒後）には約４０℃になっている。そして、搾乳口を***に当てたＢ点直後、急激に温度が低下していることから、搾乳口の内周面の温度が***に奪われていることが窺える。このことは、搾乳口を***に最初に接触した際、冷やっと感を防止できていることに他ならない。なお、実験以外の使用場面においても、搾乳口に加熱した搾乳用加温具を装着し終えた後、フード部を搾乳器本体に取り付けたり、洋服をめくったりするなどして、搾乳を始めるには相当の作業時間がかかるため、最初に搾乳口に***を接触させる際には、搾乳口の内周面の温度は（勿論、使用者の作業スピードにもよるが）３６度程度から最高温度に近似した温度に到達していることが推定できる。従って、搾乳口を***に最初に接触した際、冷やっと感を防止することができる。   As shown in FIG. 10, the temperature of the inner peripheral surface of the milking mouth before attaching the milking warming tool to the milking mouth was about 25 ° C., but about 60 seconds after heating the milking warming tool The temperature is about 40 ° C. at point B after about 90 seconds from point A attached to the outer peripheral surface of the milking mouth (when the milking mouth is applied to the breast and after about 150 seconds after heating). Then, immediately after the point B when the milking mouth is put on the breast, the temperature is suddenly lowered, so that the temperature of the inner peripheral surface of the milking mouth is taken away by the breast. This is nothing less than a cold feeling when the milking mouth first comes into contact with the breast. In addition, after using the heating device for milking heated at the milking mouth even in usage scenes other than experiments, to start milking by attaching the hood part to the milking machine body or turning the clothes, etc. Since it takes a considerable amount of work time, when the breast is first brought into contact with the milking mouth, the temperature of the inner peripheral surface of the milking mouth (of course, depending on the work speed of the user) is about 36 degrees to the maximum temperature. It can be estimated that the temperature has approximated to. Therefore, when the milking mouth first comes into contact with the breast, it is possible to prevent a feeling of coldness.

さらに、図１０に示すように、搾乳口を***に当てたＢ点から温度が急激に低下した後、逆に搾乳口の内周面の温度は僅かに上昇し、その後は、搾乳口の内周面の温度は、***に接触させている限り、僅かに低下していくものの、左程大きな変化がないことが分かる。
なお、図１０のＣ点は搾乳口を***から一時的に外した点であり、Ｃ点以降、搾乳口を再び***に当てたＤ点まで、搾乳口の内周面の温度は低下している。このことから、実際の使用場面では、***の温度も搾乳口の内周面の温度に関与していることが窺える。そして、搾乳口を再び***に当てたＤ点から搾乳を終えたＥ点までは、僅かに搾乳口の内周面の温度を持ち直しつつ、概ねその温度を維持している。実験以外の使用場面でも、図１０と同様に搾乳口は***から何度か一時的に外すかも知れないが、その回数は少なく、基本的に搾乳口は***に当て続けられるため、図１０に示す試験のように搾乳が終わるまで***の温度を下回ることは殆どない。少なくとも搾乳口を***に最初に当てる際、搾乳口の内周面の温度は少なくとも***に近い温度まで上がっているため、冷やっと感を与えることはない。 Furthermore, as shown in FIG. 10, after the temperature has suddenly dropped from point B where the milking mouth is applied to the breast, the temperature of the inner peripheral surface of the milking mouth rises slightly, and thereafter the inside of the milking mouth It can be seen that the temperature of the peripheral surface decreases slightly as long as it is in contact with the breast, but there is no significant change to the left.
In addition, the C point of FIG. 10 is a point which removed the milking mouth from the breast temporarily, and the temperature of the internal peripheral surface of a milking mouth falls from the C point to the D point which again applied the milking mouth to the breast. Yes. From this, it can be seen that in an actual use situation, the temperature of the breast is also related to the temperature of the inner peripheral surface of the milking mouth. From the point D where the milking mouth is again applied to the breast to the point E where milking is completed, the temperature of the inner peripheral surface of the milking mouth is slightly recovered, and the temperature is generally maintained. In the usage scene other than the experiment, the milking mouth may be temporarily removed from the breast several times as in FIG. 10, but the number of times is small, and the milking mouth is basically kept on the breast. Like the test shown, it rarely falls below the temperature of the breast until milking is complete. At least when the milking mouth is first applied to the breast, the temperature of the inner peripheral surface of the milking mouth has risen to at least the temperature close to the breast, so that no cold feeling is given.

以上の実験結果により、本発明の第１実施形態の構成によれば、図１に示す電子レンジで加熱した搾乳用加温具１０を搾乳口１８の外周面１８Ｄに密着するように接続させれば、搾乳する際に、搾乳口１８の内周面１８Ｂの***への接触温度が、***の温度以上であって、かつ、***が低温火傷をしない温度とすることが可能なことが分かる。   From the above experimental results, according to the configuration of the first embodiment of the present invention, the heating device 10 for milking heated by the microwave oven shown in FIG. 1 can be connected so as to be in close contact with the outer peripheral surface 18D of the milking port 18. For example, when milking, it can be seen that the contact temperature of the inner peripheral surface 18B of the milking opening 18 to the breast is equal to or higher than the temperature of the breast and the breast does not cause low-temperature burns.

ところで、上述した実施形態の被覆部１２は、シリコーン樹脂を利用して、搾乳口１８の外周面１８Ｄに対応した形状に形成されているが、本発明は必ずしもこれに限られるものではなく、例えば、本発明の第１実施形態の第１〜第３の変形例を示した図１１及び図１２のようにしてもよい。
図１１（Ａ）は第１実施形態の第１変形例に係る搾乳用加温具１００の断面を表した部分図であり、図５の円で囲った図に対応している。
この搾乳用加温具１００の被覆部４０は、シリコーン樹脂からなる部材４１だけではなく、他の構成要素と組み合わせて形成されている。
即ち、被覆部４０は、その表面（図の場合は搾乳口の外周面側の表面）４０Ａと発熱部１５との間に中空空間４２を有している。中空空間４２は空気の層であって、熱伝導率がシリコーン樹脂に比べて小さいため、断熱効果を発揮して確実に被覆部４０の表面温度を下げ、***が低温火傷をしない温度、好ましくは***への接触温度を３７〜４２℃にすることができる。
そして、中空空間４２が断熱材となる分、シリコーン樹脂からなる部材４１の量を減らして、被覆部４０全体の重量の低減できる。
なお、図１１（Ａ）の被覆部４０では、シリコーン樹脂と空気との組み合わせであるが、本発明はこれに限られず、例えば、中空空間４２を大きくすることで、シリコーン樹脂よりも熱伝導率のよい熱硬化性樹脂（例えばエポキシ樹脂）と中空空間４２との組み合わせにしてもよい。 By the way, although the coating | coated part 12 of embodiment mentioned above is formed in the shape corresponding to outer peripheral surface 18D of the milking opening 18 using a silicone resin, this invention is not necessarily restricted to this, For example, FIG. 11 and FIG. 12 showing the first to third modifications of the first embodiment of the present invention may be used.
FIG. 11A is a partial view showing a cross section of the milking warming device 100 according to the first modification of the first embodiment, and corresponds to the circled diagram in FIG. 5.
The covering portion 40 of the milking warming device 100 is formed not only by the member 41 made of silicone resin but also in combination with other components.
That is, the covering portion 40 has a hollow space 42 between its surface (in the figure, the surface on the outer peripheral surface side of the milking mouth) 40 </ b> A and the heat generating portion 15. Since the hollow space 42 is a layer of air and has a thermal conductivity smaller than that of the silicone resin, it exhibits a heat insulation effect and reliably lowers the surface temperature of the covering portion 40, and the temperature at which the breast does not cause low-temperature burns, preferably The contact temperature to the breast can be 37-42 ° C.
And since the hollow space 42 becomes a heat insulating material, the amount of the member 41 made of silicone resin can be reduced, and the weight of the entire covering portion 40 can be reduced.
11A is a combination of silicone resin and air, but the present invention is not limited to this. For example, by increasing the hollow space 42, the thermal conductivity is higher than that of the silicone resin. A combination of a good thermosetting resin (for example, epoxy resin) and the hollow space 42 may be used.

図１１（Ｂ）は第１実施形態の第２変形例に係る搾乳用加温具１０１の断面を表した部分図であり、図５の円で囲った図に対応している。
この搾乳用加温具１０１の被覆部４３は、搾乳口の外周面１８Ｄ側の表面４３Ａが、搾乳口の外周面１８Ｄに対して全体的には概ね対応した形状ではあるものの、凸部４５及び／又は凹部４６を有することで、フード部１６に接続した状態において、搾乳口の外周面１８Ｄとの間に空間Ｓが形成されるようになっている。
従って、この空間Ｓが断熱効果を発揮して、発熱部１５からフード部１６に伝わる熱を確実に減少させることができる。従って、空間Ｓが断熱効果を有する分、シリコーン樹脂の量を減らして、被覆部４３全体の重量を低減できる。 FIG. 11B is a partial view showing a cross section of the milking warming device 101 according to the second modification of the first embodiment, and corresponds to the circled diagram in FIG. 5.
The covering portion 43 of the heating device 101 for milking has a convex portion 45 and a surface 43 </ b> A on the outer peripheral surface 18 </ b> D side of the milking mouth substantially corresponding to the outer peripheral surface 18 </ b> D of the milking mouth. By having the recess 46, a space S is formed between the milking mouth and the outer peripheral surface 18D in a state where the recess 46 is connected.
Therefore, this space S exhibits a heat insulating effect, and the heat transmitted from the heat generating part 15 to the hood part 16 can be reliably reduced. Accordingly, the amount of the silicone resin can be reduced by the amount that the space S has a heat insulating effect, and the weight of the entire covering portion 43 can be reduced.

図１２は第１実施形態の第３変形例に係る搾乳用加温具１０２を接続したフード部１６の斜視図である。
この搾乳用加温具１０２は、上述した実施形態と同様、貫通孔８から外側に拡がり、搾乳口１８の略ラッパ状の周方向Ｒに沿って配置される拡張部１２Ｂを有しているが、図１２の拡張部１２Ｂは、該周方向Ｒの一部が途切れた途切れ部８０を有する。この途切れ部８０は、拡張部１２Ｂの貫通孔８から一部の外縁部２４まで延びる切り欠き部であるとも言え、一箇所に形成されている。
そうすると、拡張部１２Ｂは可撓性を備えた弾性体であるシリコーン樹脂をベースに形成されているため、この途切れ部８０の周方向Ｒの寸法を手で拡げることが可能である。従って、搾乳用加温具１０２は、それを接続しようとするフード部１６が多少大きくても、周方向Ｒの寸法を大きく変化させて接続することができる。
また、拡張部１２Ｂは弾性力も有するため、手で途切れ部８０の周方向Ｒの寸法を一時的に大きくして搾乳口に接続した後は、該弾性力により搾乳口１８への密着性を高めることができる。
なお、図１２の途切れ部８０は空隙となっているが、本発明はこれに限られるものではなく、例えば、途切れ部８０の領域に対して、被覆部１２のシリコーン樹脂よりも伸縮性の高い弾性体を配設してもよい。 FIG. 12 is a perspective view of the hood portion 16 to which the milking warming device 102 according to the third modification of the first embodiment is connected.
Although this heating device 102 for milking has the expansion part 12B which spreads outside from the through-hole 8 similarly to embodiment mentioned above, and is arrange | positioned along the substantially trumpet-shaped circumferential direction R of the milking opening 18. The extended portion 12B of FIG. 12 has a discontinuous portion 80 in which a part of the circumferential direction R is discontinuous. This discontinuous portion 80 can be said to be a cutout portion extending from the through hole 8 of the expansion portion 12B to a part of the outer edge portion 24, and is formed at one location.
Then, since the extended portion 12B is formed on the basis of a silicone resin that is an elastic body having flexibility, the dimension in the circumferential direction R of the interrupted portion 80 can be increased by hand. Therefore, even if the food | hood part 16 which is going to connect it is somewhat large, the heating tool 102 for milking can be connected by changing the dimension of the circumferential direction R largely.
Moreover, since the extension part 12B also has elastic force, after connecting the breast pumping mouth by temporarily enlarging the dimension of the circumferential direction R of the interrupting part 80 by hand, the adhesiveness to the milking mouth 18 is enhanced by the elastic force. be able to.
12 is a gap, the present invention is not limited to this. For example, the region of the interrupted portion 80 has higher elasticity than the silicone resin of the covering portion 12. An elastic body may be provided.

〔第１実施形態の搾乳器の変形例〕
図１３は、図１の搾乳用加温具１０を利用した搾乳器１０３側の変形例に係る斜視図である。なお、図１３では、搾乳用加温具１０の一部を切り欠いて図示している。
図１３において、図１〜図１２で用いた符号と同一の符号を付した箇所は共通する構成であるから、重複した説明は省略し、以下、相違点を中心に説明する。
この搾乳器１０３では、搾乳用加温具１０は上述した第１実施形態と同じであるが、これを接続した搾乳器側の構成が異なっている。 [Variation of the breast pump of the first embodiment]
FIG. 13 is a perspective view according to a modification on the milking machine 103 side using the milking warming tool 10 of FIG. 1. In FIG. 13, a part of the milking warming tool 10 is cut out.
In FIG. 13, the portions denoted by the same reference numerals as those used in FIGS. 1 to 12 have a common configuration, and therefore, a duplicate description will be omitted, and the following description will focus on differences.
In this milking machine 103, although the milking warming tool 10 is the same as 1st Embodiment mentioned above, the structure by the side of the milking machine which connected this is different.

即ち、図１３の搾乳器１０３は電動式になっており、搾乳ユニット５５と、この搾乳ユニット５５とパイプ４４により接続された圧力変更手段としてのポンプユニット５７とを備えている。
搾乳ユニット５５は、上述したボトル１１、フード部１６、及びこれらを着脱できる搾乳器本体２１を備えている。これらの構成は、後述するフード部１６に設けられた温度センサ５９を除き、既に説明したので省略する。
搾乳器本体２１の上部には、ポンプユニット５７で調整された圧力が伝えられる圧力伝達部５４が着脱可能に接続されている。圧力伝達部５４の密封された内側空間には、弾性力のあるダイヤフラム（不図示）が収容されており、このダイヤフラムの動きによりフード部１６内を負圧にしたり、その負圧状態を解除したりしている。 That is, the breast pump 103 in FIG. 13 is an electric type, and includes a milking unit 55 and a pump unit 57 as pressure changing means connected to the milking unit 55 by the pipe 44.
The milking unit 55 includes the bottle 11, the hood portion 16, and the breast pump main body 21 to which these can be attached and detached. Since these configurations have already been described except for a temperature sensor 59 provided in the hood portion 16 described later, a description thereof will be omitted.
A pressure transmission unit 54 to which the pressure adjusted by the pump unit 57 is transmitted is detachably connected to the upper portion of the breast pump main body 21. An elastic diaphragm (not shown) is accommodated in the sealed inner space of the pressure transmission part 54. The movement of the diaphragm makes the inside of the hood part 16 negative or releases the negative pressure state. It is.

ポンプユニット５７は、この圧力伝達部５４と可撓性のパイプ４４を介して接続されている。ポンプユニット５７は、真空ポンプとして、スイッチＳＷがオンされると、搾乳ユニット５０の圧力伝達部５４内の空間を負圧に引いたり、この負圧状態から大気圧状態まで戻したりして、圧力の変動を連続して行い（これが脈動となる）、これにより、圧力伝達部５４内のダイヤフラムを動かしている。
また、図のポンプユニット５７には、負圧形成における脈動の周期を調整するためのサイクルノブ３８と、負圧の圧力を調整するためのツマミ３７が設けられている。
これらスイッチＳＷ、サイクルノブ３８、ツマミ３７は、ポンプユニット５７内の制御部６０と電気的に接続され、制御部６０はこれらのスイッチ類ＳＷ，３７，３８の作動に従って、真空ポンプ（不図示）を制御するようになっている。
制御部６０は、全体的な動作の制御を行うものであり、例えばワンチップのマイクロコンピュータを用いており、ＲＯＭ（読み出し専用メモリ）、ＲＡＭ（ランダムアクセスメモリ）、不揮発性メモリ、クロックを有している。 The pump unit 57 is connected to the pressure transmission unit 54 via a flexible pipe 44. When the switch SW is turned on as a vacuum pump, the pump unit 57 pulls the space in the pressure transmission unit 54 of the milking unit 50 to a negative pressure, or returns the pressure from the negative pressure state to the atmospheric pressure state. Are continuously performed (this becomes a pulsation), thereby moving the diaphragm in the pressure transmission unit 54.
Further, the pump unit 57 shown in the figure is provided with a cycle knob 38 for adjusting the period of pulsation in forming negative pressure and a knob 37 for adjusting the pressure of negative pressure.
The switch SW, the cycle knob 38, and the knob 37 are electrically connected to a control unit 60 in the pump unit 57. The control unit 60 is a vacuum pump (not shown) according to the operation of the switches SW, 37, and 38. Is to control.
The control unit 60 controls the overall operation, and uses, for example, a one-chip microcomputer, and has a ROM (Read Only Memory), a RAM (Random Access Memory), a nonvolatile memory, and a clock. ing.

ここで、フード部１６は、搾乳用加温具１０が接続される領域（図の場合は、搾乳口１８の外周面１８Ｄであって発熱部と対向する領域）に温度センサ５９を有している。温度センサ５９は、搾乳用加温具１０の搾乳口１８側の面（即ち、図５に示す被覆部１２の内側面１２Ｄ）の温度を測定する測温計であり、サーミスタ薄膜形測温体等の公知のセンサを用いることができる。
そして、搾乳器１０３には、温度センサ５９からの信号ＳＧに基づいて、***の低温火傷を招く温度以上であることを使用者に報知する報知部２２が設けられている。報知部２２は、図ではポンプユニット５７に設けられたＬＥＤや液晶などからなる表示部である。
具体的には、温度センサ５９からの信号ＳＧは、ポンプユニット５７内の制御部６０に送信されるようになっている（図示していないが、データ信号ＳＧはパイプ４４内の信号線を通って制御部６０に送信される）。信号ＳＧを受信した制御部６０は、ＲＯＭに書き込まれたデータテーブルに基づいて、報知部２２を駆動させるか否かを決定する。データテーブルには、図６の「被覆部の内側面の温度」と、それに対応した「搾乳口の内周面の温度」のデータが格納されており、これにより、制御部６０は、例えば「被覆部の内側面の温度」が５９℃を超えていた場合、「搾乳口の内周面の温度」が４６℃を超えていると判断して、低温火傷になる恐れがあるという警告を図１３の表示部３７に出すように、表示部ドライバ６９に信号を送り、表示部ドライバ６９はその命令に基づいて報知部２２を駆動するようになっている。 Here, the hood part 16 has a temperature sensor 59 in a region to which the milking warming tool 10 is connected (in the case of the drawing, the outer peripheral surface 18D of the milking port 18 and the region facing the heat generating part). Yes. The temperature sensor 59 is a thermometer that measures the temperature of the surface on the milking mouth 18 side of the heating device 10 for milking (that is, the inner surface 12D of the covering portion 12 shown in FIG. 5), and is a thermistor thin film temperature sensor. It is possible to use a known sensor such as.
And the milking machine 103 is provided with the alerting | reporting part 22 which alert | reports to a user that it is more than the temperature which causes the low-temperature burn of a breast based on the signal SG from the temperature sensor 59. FIG. In the drawing, the notification unit 22 is a display unit made of an LED, liquid crystal, or the like provided in the pump unit 57.
Specifically, the signal SG from the temperature sensor 59 is transmitted to the control unit 60 in the pump unit 57 (not shown, but the data signal SG passes through the signal line in the pipe 44. Transmitted to the control unit 60). The control unit 60 that has received the signal SG determines whether to drive the notification unit 22 based on the data table written in the ROM. In the data table, “temperature of the inner surface of the covering portion” in FIG. 6 and data corresponding to “temperature of the inner peripheral surface of the milking mouth” in FIG. 6 are stored. When the “temperature of the inner surface of the covering part” exceeds 59 ° C., it is judged that the “temperature of the inner peripheral surface of the milking mouth” exceeds 46 ° C. A signal is sent to the display unit driver 69 so as to be displayed on the 13 display units 37, and the display unit driver 69 drives the notification unit 22 based on the command.

本変形例の搾乳器１０３は以上のように構成されており、搾乳用加温具１０は手動式だけでなく電動式搾乳器にも利用可能であり、さらに、使用者が仕様とは異なる使い方をし、***加温具１０を加熱し過ぎたとしても、温度センサ５９がそれを感知して、報知部２２でそれを使用者に知らせることができる。即ち、***への搾乳口を介した接触温度が低温火傷を招く温度以下にするためには、上述したように、板状の発熱部がシリコーン樹脂にフェライトを配合したものであり、このシリコーン樹脂とフェライトの重量比が約２：１〜９：１、発熱部の厚みが０．５〜３ｍｍ、被覆部の発熱部から内側面までの厚みが０．５〜３ｍｍであることが必要である。この点、この構成で低温火傷を防止するには、使用者側の使用条件について、例えば５００Ｗの電子レンジであれば、加熱時間を約３０〜９０秒とする必要がある。しかし、この使用条件は使用者によっては守ることができない場合があり、その場合は低温火傷（火傷を含む）を起こす恐れがある。そこで、温度センサ５９が低温火傷を招く所要の温度以上となった場合、報知部２２でそのことを使用者に知らせるようにした。
なお、図１３では報知部２２は表示部とされているが、本発明はこれに限られず、報知部２２をブザーやスピーカーにして、温度センサ５９の検出結果に基づいて、音で使用者に危険を知らせてもよい。 The milking device 103 of this modification is configured as described above, and the heating device 10 for milking can be used not only for the manual type but also for the electric type milking device. Even if the breast heating device 10 is heated too much, the temperature sensor 59 can detect it and notify the user by the notification unit 22. That is, in order for the contact temperature to the breast through the milking mouth to be equal to or lower than the temperature causing low-temperature burns, as described above, the plate-like heat generating portion is obtained by blending ferrite with silicone resin. The weight ratio of ferrite to ferrite is about 2: 1 to 9: 1, the thickness of the heat generating part is 0.5 to 3 mm, and the thickness from the heat generating part to the inner surface of the covering part is 0.5 to 3 mm. . In this regard, in order to prevent low-temperature burns with this configuration, for example, in the case of a 500 W microwave oven, it is necessary to set the heating time to about 30 to 90 seconds. However, this usage condition may not be able to be observed depending on the user, in which case there is a risk of low temperature burns (including burns). Therefore, when the temperature sensor 59 reaches a required temperature that causes low-temperature burns, the notification unit 22 notifies the user of this fact.
In addition, although the alerting | reporting part 22 is made into the display part in FIG. 13, this invention is not restricted to this, The alerting | reporting part 22 is made into a buzzer or a speaker, and a user is sounded based on the detection result of the temperature sensor 59. You may be informed of the danger.

〔第２実施形態〕
図１４は、本発明の第２実施形態に係る搾乳用加温具１０を有するフード部１０４の斜視図、図１５は図１４のＡ−Ａ断面図である。
これらの図において、図１〜図１３で用いた符号と同一の符号を付した箇所は共通する構成であるから、重複した説明は省略し、以下、相違点を中心に説明する。
図１４及び図１５のフード部１０４が上述した実施形態と異なるのは、搾乳用加温具１０を固定している点である。 [Second Embodiment]
14 is a perspective view of the hood 104 having the milking warming device 10 according to the second embodiment of the present invention, and FIG. 15 is a cross-sectional view taken along line AA of FIG.
In these drawings, the portions denoted by the same reference numerals as those used in FIG. 1 to FIG. 13 have the same configuration, and therefore, a duplicate description will be omitted, and the differences will be mainly described below.
14 and 15 is different from the embodiment described above in that the milking warming tool 10 is fixed.

すなわち、フード部１０４は、異なる素材である「搾乳口１８及び筒状部１９」と「搾乳用加温具１０」とを二色成形で一体的に形成することで、搾乳用加温具１０は搾乳口１８と分離不可能に接続されている。
具体的には、搾乳用加温具１０は、第１実施形態で説明した構成と同様、シリコーン樹脂にフェライトを配合した発熱部１５と、この発熱部１５の全体を覆う熱硬化性樹脂（例えばシリコーン樹脂）製の被覆部１２とを有し、この被覆部１２の部分が搾乳口１８と二色成形で形成されている。発熱部１５については、例えば、被覆部１２内に発熱部１５を収容可能な空間と、該空間と繋がった切れ目（不図示）とを形成し、該切れ目から発熱部１５を被覆部１２内の該空間に挿入した後、該切れ目を接着するなどして閉じればよい。
なお、搾乳口１８及び筒状部１９は、第１実施形態と同様に、ポリプロピレンなどの熱可塑性樹脂でも構わないが、もしも搾乳用加温具１０を加熱し過ぎた場合、熱可塑性樹脂では溶融の恐れもある。このため、搾乳口１８及び筒状部１９は熱硬化性樹脂から形成するのが好ましい。 That is, the hood part 104 integrally forms the “milking opening 18 and the cylindrical part 19” and the “milking heating tool 10”, which are different materials, by two-color molding, so that the milking heating tool 10 is formed. Is connected to the milking mouth 18 inseparably.
Specifically, the milking warming device 10 is similar to the configuration described in the first embodiment, in which the heat generating portion 15 is a silicone resin blended with ferrite and a thermosetting resin (for example, covering the entire heat generating portion 15). (Silicone resin) covering portion 12, and the portion of the covering portion 12 is formed by milking mouth 18 and two-color molding. For the heat generating part 15, for example, a space capable of accommodating the heat generating part 15 in the covering part 12 and a cut (not shown) connected to the space are formed, and the heat generating part 15 is connected to the inside of the covering part 12 from the cut. After being inserted into the space, the cut may be closed by bonding or the like.
The milking mouth 18 and the cylindrical portion 19 may be a thermoplastic resin such as polypropylene as in the first embodiment. However, if the heating device 10 for milking is heated too much, the thermoplastic resin melts. There is also a fear.

図１６において、図１〜図１５で用いた符号と同一の符号を付した箇所は共通する構成であるから、重複した説明は省略し、以下、相違点を中心に説明する。
図１６の搾乳用加温具１０５が上述した実施形態と異なるのは、搾乳口１８の内周面１８Ｂに配置される点である。 [Third Embodiment]
FIG. 16 is a schematic longitudinal sectional view in which the milking warming device 105 according to the third embodiment of the present invention is connected to the hood portion 16 and cut in the longitudinal direction. 16 is an enlarged cross-sectional view around the heat generating portion 65 and the covering portion 66. Except for this enlarged cross-sectional view, the parallel oblique lines indicating the cross-section are omitted in FIG.
In FIG. 16, the portions denoted by the same reference numerals as those used in FIG. 1 to FIG. 15 have a common configuration, and thus a duplicate description will be omitted, and the following description will focus on the differences.
The milking warming device 105 of FIG. 16 is different from the above-described embodiment in that it is arranged on the inner peripheral surface 18B of the milking mouth 18.

即ち、図１６の搾乳用加温具１０５における発熱部６５や被覆部６６の素材は、図１〜図５の発熱部１５や被覆部１２と素材と基本的には同じであるが、その形状が異なっている。
具体的には、図１６の発熱部６５はシリコーン樹脂をベースにフェライトを配合した可撓性部材、被覆部６６はシリコーン樹脂からなる可撓性のある弾性体からなっているが、これら発熱部６５及び被覆部６６を含む搾乳用加温具１０５は、搾乳口１８の内周面１８Ｂに配置される構造とされ、***が直接、被覆部６６に接触するようになっている。
図１６の搾乳用加温具１０５では、搾乳口１８の拡径部１８Ｃ側において、搾乳口１８の内周面１８Ｂの形状に概ね沿った略ラッパ状とされ、搾乳口１８の内周面１８Ｂとの間に所定の空間Ｓ４を有するようにして、搾乳口１８の内側に入り込むようにして装着される。
また、搾乳用加温具１０５は、使用者の***を当接させた状態で、乳首が挿入される貫通孔７５と、この貫通孔７５よりも拡径部１８Ｃ側に設けられ、乳輪側に突出する同心円状の突出部であって、使用者の乳輪に当接する乳輪当接部７８と、この乳輪当接部７８よりも拡径部１８Ｃ側に設けられ、***側に突出する同心円状の突出部であって、使用者の***に密着する***密着部７９を備えている。 That is, the material of the heat generating part 65 and the covering part 66 in the heating device 105 for milking in FIG. 16 is basically the same as that of the heat generating part 15 and the covering part 12 in FIGS. Is different.
Specifically, the heat generating portion 65 in FIG. 16 is made of a flexible member in which ferrite is blended based on a silicone resin, and the covering portion 66 is made of a flexible elastic body made of silicone resin. The milking warming device 105 including 65 and the covering portion 66 has a structure arranged on the inner peripheral surface 18B of the milking opening 18 so that the breast directly contacts the covering portion 66.
In the milking warming device 105 of FIG. 16, the milking mouth 18 has a substantially trumpet shape generally along the shape of the inner peripheral surface 18 </ b> B of the milking mouth 18 on the enlarged diameter portion 18 </ b> C side of the milking mouth 18. It is attached so that it may enter inside milking mouth 18 so that it may have predetermined space S4 between.
Further, the milking warming device 105 is provided on the side of the areola with the through hole 75 into which the nipple is inserted and the enlarged diameter portion 18C side than the through hole 75 in a state where the breast of the user is brought into contact. A concentric projecting portion that protrudes toward the breast, and is provided on the side of the enlarged diameter portion 18C from the areola contact portion 78 that contacts the user's areola, and protrudes toward the breast. It has a concentric protrusion that is a breast contact portion 79 that is in close contact with the breast of the user.

従って、搾乳用加温具１０５は、搾乳口カバーとしての機能も兼ねることができる。即ち、***が搾乳器に吸い込まれた際にクッションになり、痛みを和らげることができる。また、搾乳口１８と***の形状が合致していなくても、確実に***と搾乳用加温具１０５の被覆部６６とを密着させて乳首周辺の空間を負圧にし、搾乳を行うことができる。しかも、本実施形態の場合、***が被覆部６６内に受容された状態で、乳輪には乳輪当接部７８が当たるため、負圧による吸引力で母乳が吸い出されることに加えて、乳輪当接部７８がこの乳輪を効果的に押すことにより、母乳の出を良くすることができる。そして、***密着部８０が***に密接に面状に当接してシールすることにより、負圧の外部へのリークを防止するとともに、母乳の外部への漏れを効果的に防止することができる。   Therefore, the milking warming device 105 can also serve as a milking mouth cover. That is, when the breast is sucked into the breast pump, it becomes a cushion and can relieve pain. Further, even if the milking mouth 18 and the shape of the breast do not match, the breast and the covering portion 66 of the milking warming device 105 are surely brought into close contact with each other so that the space around the nipple is made negative pressure and milking is performed. it can. In addition, in the case of the present embodiment, since the areola is in contact with the areola in the state where the breast is received in the covering portion 66, the breast milk is sucked out by the suction force due to the negative pressure. When the areola contact portion 78 effectively pushes the areola, the milk can be improved. Then, the breast contact portion 80 is in close contact with the breast in a planar shape and sealed, thereby preventing leakage of negative pressure to the outside and effectively preventing leakage of breast milk to the outside.

このような搾乳用加温具１０５は、搾乳口１８の外縁部２４に対して着脱可能に接続される。図の場合、被覆部６６の外面には、狭い溝状部７４を有する取付け部７６が設けられ、この溝状部７４に対して搾乳口１８のラッパ状に開いた外縁部２４が嵌入して装着される。なお、被覆部６６は所定の可撓性及び弾力性を有することから、この取付け部７４を手指にて外方にめくることが可能であり、これにより搾乳用加温具１０５を搾乳口１８から取り外すことができる。   Such a milking warming device 105 is detachably connected to the outer edge 24 of the milking port 18. In the case of the figure, a mounting portion 76 having a narrow groove-shaped portion 74 is provided on the outer surface of the covering portion 66, and the outer edge portion 24 opened in a trumpet shape of the milking mouth 18 is fitted into the groove-shaped portion 74. Installed. In addition, since the coating | coated part 66 has predetermined | prescribed flexibility and elasticity, it is possible to turn this attachment part 74 outward with a finger | toe, and, thereby, the heating tool 105 for milking can be turned off from the milking mouth 18. Can be removed.

ここで、被覆部６６は、発熱部６５から***と接触する内面８０までの厚み方向の寸法Ｄ４が、図５の厚み方向の寸法Ｄ１に比べて大きく、例えば約４ｍｍ以上とされている。また、図１６の発熱部６５の厚み方向の寸法Ｄ５は図５の寸法Ｄ２と同等以下とされ、０．５ｍｍ以下とされている。このようにして、図１６の被覆部６６の内面８０は***に直接接触しても低温火傷しない温度（約４６℃）以下となるようにされ、更に、***が接触した際のクッション性を高めている。
なお、被覆部６６の発熱部６５から内面８０までの寸法Ｄ４は上記寸法に限られることなく、例えば、発熱部６５のシリコーン樹脂とフェライトの重量比を９：１にして、発熱部６５を加熱し難くすることで該寸法Ｄ４を抑制して重量の増大を防止するようにしてもよい。但し、該寸法Ｄ４を小さくすることは、被覆部６６のクッション性を低下させることになるため、好ましくは、被覆部６６の内面８０とは反対側の外面８１から発熱部６５までの厚み方向の寸法Ｄ６を、該寸法Ｄ４に比べて小さくし、これにより、該寸法Ｄ４が大きくても、搾乳用加温具１０５の重量の大幅な増加を防止するとよい。
また、被覆部６６はＪＩＳ硬度２０ないし８０程度のシリコーン樹脂を使用するのが好ましく、これにより***が接触した際に好ましい弾力性を発揮することができる。 Here, in the covering portion 66, the dimension D4 in the thickness direction from the heat generating portion 65 to the inner surface 80 in contact with the breast is larger than the dimension D1 in the thickness direction in FIG. 5, for example, about 4 mm or more. Further, the dimension D5 in the thickness direction of the heat generating portion 65 in FIG. 16 is equal to or less than the dimension D2 in FIG. 5 and is 0.5 mm or less. In this manner, the inner surface 80 of the covering portion 66 in FIG. 16 is set to a temperature (about 46 ° C.) or lower that does not cause low-temperature burns even if it directly contacts the breast, and further enhances cushioning when the breast contacts. ing.
Note that the dimension D4 from the heat generating portion 65 to the inner surface 80 of the covering portion 66 is not limited to the above dimensions. For example, the heat generating portion 65 is heated by setting the weight ratio of the silicone resin and ferrite of the heat generating portion 65 to 9: 1. By making it difficult, the dimension D4 may be suppressed to prevent an increase in weight. However, since reducing the dimension D4 reduces the cushioning property of the covering portion 66, it is preferable to reduce the dimension D4 in the thickness direction from the outer surface 81 opposite to the inner surface 80 of the covering portion 66 to the heat generating portion 65. The dimension D6 is preferably made smaller than the dimension D4, thereby preventing a significant increase in the weight of the milking warming device 105 even if the dimension D4 is large.
In addition, it is preferable to use a silicone resin having a JIS hardness of about 20 to 80 for the covering portion 66, so that a preferable elasticity can be exhibited when the breast comes into contact.
