Description

特許法第30条第2項適用 畿央大学大学院健康科学科2021年度修士論文中間発表に関して、令和3年9月3日~20日の間、本願発明(又はその概要)が記載された修士論文等が、中間発表参加者全員に閲覧可能となった。Application of Article 30, Paragraph 2 of the Patent Act Regarding the interim presentation of the 2021 master's thesis in the Department of Health Sciences, Kio University, the master's thesis in which the invention of the present application (or its outline) was described from September 3 to 20, 1991. Etc. can be viewed by all participants in the interim presentation.

本発明は、妊産婦用の乳汁分泌促進器に関する。より具体的には、たとえば妊産婦用ブラジャーに内装し、乳首の奥に位置する乳管集約部を自動的に反復マッサージして乳汁の分泌を促進できる、軽量かつハンズフリーな乳汁分泌促進器に関するものである。 The present invention relates to a milk secretion promoter for pregnant women. More specifically, it is related to a lightweight, hands-free milk secretion promoter that can be installed in a maternal brassiere, for example, and automatically and repeatedly massage the ductal agglomeration located at the back of the nipple to promote milk secretion. Is.

新生児の発育にとっての母乳保育の有用性は広く知られており、約9割を超える妊婦が母乳保育を希望するが、生後1カ月時点での母乳保育率は約5割であり、このギャップは母乳保育の困難性を示している。母乳保育の確立には***へのケア、具体的には乳頭刺激・乳管開通操作が重要であり、そのセルフケアの促進が求められている。 The usefulness of breastfeeding for the development of newborns is widely known, and more than 90% of pregnant women desire breastfeeding, but the breastfeeding rate at the first month of life is about 50%, and this gap is It shows the difficulty of breastfeeding. Breast care, specifically nipple stimulation and duct opening operations, is important for establishing breastfeeding, and promotion of self-care is required.

図1に示すように、乳汁は***内部の乳腺から乳管を経て乳頭(乳首)から分泌されるが、乳頭の先端から奥に向かって半径2~3cmの範囲に乳管が集約する乳管集約部が存在する。乳管開通操作は、乳管集約部の中心深部に反復的に圧迫を加えることによって行う。 As shown in FIG. 1, milk is secreted from the mammary gland inside the breast via the duct and from the nipple (nipple), but the duct is concentrated within a radius of 2 to 3 cm from the tip of the nipple to the back. There is an aggregate. The duct opening operation is performed by repeatedly applying compression to the central deep part of the duct consolidating portion.

乳汁分泌促進のために、新生児の吸啜(きゅうてつ)や助産師の乳頭乳輪部マッサージと同等の効果を得るためには、褥婦の***において前記乳管集約部、特にその中心深部を圧迫する乳管開通操作が必要である。助産師が行う乳管開通促進・乳汁分泌促進の手技には、主に2指法と3指法があり、乳管集約部の中心深部への作用の点では、図2に示すとおり、母指・人差指の指腹、中指の第一関節人差指側側部を力点として動作させる3指法がより有効とされている。 In order to obtain the same effect as sucking of a newborn baby or massaging the areola of the nipple of a midwife to promote lactation, the ductal aggregation part, especially the deep part of the center of the breast of a decubitus woman. It is necessary to open the breast duct to press it. There are mainly two-finger and three-finger methods for the duct opening promotion and milk secretion promotion techniques performed by midwives. It is said that the three-finger method, in which the finger pad of the index finger and the side of the first joint of the middle finger on the side of the index finger are used as the points of emphasis, is more effective.

多くの病産院では吸引圧で搾乳する電動搾乳器が導入されているが、適切な乳頭刺激・乳管開通操作が可能なものは普及しておらず、機器の重量やコスト、使用時に手がふさがり座位を強いられる等の点で手軽さに欠け、家庭でのセルフケアには適さない。 Many hospitals have introduced electric breast pumps that use suction pressure to milk, but those that can perform appropriate nipple stimulation and duct opening operations are not widespread, and the weight and cost of the equipment and the hand when using it are difficult. It lacks convenience in that it is forced to sit in a closed position and is not suitable for self-care at home.

一方、乳汁分泌促進のための乳頭乳輪部マッサージを器具によって行う従来技術としては、たとえば、特許文献1、2に開示されるような発明が提案されている。
特開平9-66085公開特許公報 特表2005-504587号公表特許公報
On the other hand, as a conventional technique for performing a nipple areola massage for promoting milk secretion with an instrument, for example, inventions disclosed in Patent Documents 1 and 2 have been proposed.
Japanese Patent Application Laid-Open No. 9-66085 Japanese Patent Publication No. 2005-504587

特許文献1に係る乳首マッサージ器は、***を覆う本体ケーシングの内面頂部に開口された乳首挿入孔内で、電動リンク機構で開閉する長短のアーム5に乳首側部を間欠的に挟む動作をさせるとともに、回転体12に設けた突起部13によって乳首を刺激するものである。しかし、アーム5は2方向からハサミのように乳首の基部を挟んで圧迫する構成であり、突起部13も回転しながら乳首側面を摩擦して刺戟する構成であって、乳管集約部の中心深部を圧迫する作用は想定していない。 The nipple massager according to Patent Document 1 has an operation of intermittently sandwiching the nipple side portion between long and short arms 5 opened and closed by an electric link mechanism in a nipple insertion hole opened at the top of the inner surface of the main body casing covering the breast. At the same time, the nipple is stimulated by the protrusion 13 provided on the rotating body 12. However, the arm 5 is configured to sandwich and press the base of the nipple from two directions like scissors, and the protrusion 13 is also configured to rub and stimulate the side surface of the nipple while rotating, and is the center of the duct collecting portion. The action of pressing deep is not assumed.

特許文献2に係る母乳搾乳システムは、母乳を搾取して収集容器212に収集するための発明であり、複数の加圧チャンバ802、あるいはビーズを備えたアレイ状の搾乳機構1314などにより***全体を乳首側に向けて圧迫する構成である。これらはいずれも、基本的に乳管が十分に開通済みの褥婦の***から文字通り乳汁を搾り取る構成であり、乳管集約部の中心深部を選択的に圧迫する作用は想定しておらず、乳管開通が不十分な褥婦に適したものではない。 The breast milk milking system according to Patent Document 2 is an invention for extracting breast milk and collecting it in a collection container 212, and the entire breast is covered by a plurality of pressurizing chambers 802, an array-shaped milking mechanism 1314 provided with beads, or the like. It is a configuration that presses toward the nipple side. All of these are basically structures that literally squeeze milk from the breast of a decubitus woman whose duct has been fully opened, and do not assume the action of selectively pressing the central deep part of the duct aggregation part. Not suitable for decubitus women with inadequate duct opening.

また、これら従来技術はいずれも構造が複雑で、重量やコスト、使用時に手がふさがり、座位を強いられる等の点で手軽さに欠けるという問題は解決しておらず、やはり家庭でのセルフケアには適さない。 In addition, all of these conventional techniques have a complicated structure, and the problems of lack of convenience in terms of weight, cost, clogging of hands when used, and forced sitting position have not been solved, and they are still suitable for self-care at home. Is not suitable.

さらにいえば、人体の中でも特に柔らかく繊細な***及び乳輪部・乳頭部に作用する以上、器具による動作自体が機械的な硬い動作にならず、新生児の吸啜運動や助産師の手指の動きを模倣できることが望ましいが、これら先行技術の動作は、いずれもこうした模倣とは程遠いものである。 Furthermore, as long as it acts on the breast, areola, and nipple, which are particularly soft and delicate in the human body, the movement itself by the instrument does not become a mechanically stiff movement, and the sucking movement of the newborn and the movement of the fingers of the midwife. It is desirable to be able to imitate, but the behavior of these prior arts is far from such imitation.

本発明は、従来技術のかかる問題点を解決しようとするものであり、新生児の吸啜運動や助産師の手指の動きによる乳管集約部の中心深部への選択的な圧迫を再現可能とし、かつ、育児や家事または休息中にも使用時の姿勢を選ばない、家庭でも手軽に使用できる軽量・コンパクト・低コストな乳汁分泌促進器を提供することを課題とする。 The present invention is to solve the problems of the prior art, and makes it possible to reproduce the selective compression of the breast duct concentrating part to the central deep part by the sucking movement of the newborn baby and the movement of the fingers of the midwife. Another object of the present invention is to provide a lightweight, compact, and low-cost milk secretion promoter that can be easily used at home regardless of the posture during use during childcare, housework, or rest.

(人工筋肉リング)
前記人工筋肉リングとしては、円環内径が反復的に収縮する動作が可能で、軽量かつ耐久性に優れ、低コストで実装可能なものであればその方式や構造は問わないが、人体親和性に優れ、人体の筋肉と同様の動作が可能な人工筋肉を、乳管集約部の周囲に効率良く圧迫効果が作用するようにリング状に形成したものが適用可能である。かかる人工筋肉として、たとえば、マッキベン(McKibben)式人工筋肉が好適である。
(Artificial muscle ring)
The artificial muscle ring can be operated to repeatedly contract the inner diameter of the annulus, is lightweight, has excellent durability, and can be mounted at low cost, regardless of its method or structure, but is compatible with the human body. It is possible to apply an artificial muscle that is excellent in the above and can move in the same manner as the muscle of the human body, and is formed in a ring shape so that the compression effect acts efficiently around the duct consolidating part. As such an artificial muscle, for example, a McKibben type artificial muscle is suitable.

マッキベン式人工筋肉は、天然ゴムやウレタンゴム等製の弾性体チューブの外周に合成樹脂繊維を螺旋状の網目に織った筒状のスリーブを被せた上で、空気の吸排機構を備える一対のターミナルにて両端を固定封鎖し、弾性体チューブを外部から印加する空気圧で膨張させることにより全長を収縮させるものである。スリーブは、網目の角度がアコーディオンのように変化することにより、軸方向に押し込むと半径が太くなり、逆に引っ張ると半径が細くなる構造を有する。そのため、内蔵する弾性体チューブに空気圧が印加されて軸方向と半径方向に膨張しようとする際に、スリーブが半径方向の膨張を取り出して網目の角度を変化させることで弾性体チューブに軸方向の収縮力を生じさせることを原理としている。かかるマッキベン式人工筋肉の両端を接続してリング状にすることで、膨張時に断面が円形に拡張すると、リングの円環内径が縮小する。 The Macchiben artificial muscle is a pair of terminals equipped with an air suction / exhaust mechanism after covering the outer circumference of an elastic tube made of natural rubber, urethane rubber, etc. with a tubular sleeve woven with synthetic resin fibers in a spiral mesh. Both ends are fixed and sealed, and the elastic tube is expanded by the air pressure applied from the outside to contract the entire length. The sleeve has a structure in which the angle of the mesh changes like an accordion, so that the radius becomes thicker when pushed in the axial direction, and the radius becomes thinner when pulled in the opposite direction. Therefore, when air pressure is applied to the built-in elastic tube and it tries to expand in the axial and radial directions, the sleeve takes out the radial expansion and changes the angle of the mesh, so that the elastic tube is axially expanded. The principle is to generate a contraction force. By connecting both ends of the McKibben artificial muscle to form a ring, when the cross section expands in a circular shape during expansion, the inner diameter of the annulus of the ring is reduced.

また、マッキベン式人工筋肉は、電動式・電磁式、あるいは油圧シリンダ式のアクチュエータに比べて、軽量で出力密度が高い(自重が小さいのに大きな力が出る)、耐環境性に優れている(錆びや埃に強い)、構造がシンプルかつ軽量、メンテナンスが容易で製造コストが小さく、柔軟性が高く人間の筋特性に近い特性を有している。 In addition, the Macchiben type artificial muscle is lighter in weight, has a higher output density (a large force is generated even though its own weight is small), and has excellent environmental resistance compared to electric, electromagnetic, or hydraulic cylinder type actuators. (Resistant to rust and dust), simple structure and light weight, easy maintenance, low manufacturing cost, high flexibility and characteristics close to human muscle characteristics.

(軟突起)
軟突起は、人間の手指の動きを模倣する本発明独自の構成である。その材質は特に限定されないが、たとえば、指先に近い柔らかさのウレタンゴム塊が好適である。前述のとおり、マッキベン式人工筋肉を使用した人工筋肉リングでは、内蔵する弾性体チューブを圧縮空気で加減圧することで、円環内径を反復的に拡縮可能である。
(Soft protrusion)
The soft protrusion is a unique configuration of the present invention that mimics the movement of human fingers. The material is not particularly limited, but for example, a urethane rubber lump having a softness close to that of a fingertip is suitable. As described above, in the artificial muscle ring using the Macchiben type artificial muscle, the inner diameter of the annulus can be repeatedly expanded and contracted by pressurizing and depressurizing the built-in elastic tube with compressed air.

妊産婦の***に装着した場合、円環内径の拡縮は***の軸線に対し垂直方向の拡縮となるため、人工筋肉リングのみでも、収縮時には乳管集約部周囲に均等に圧迫力を掛けて乳汁を「搾る」作用は生じる。しかし、前述のとおり、乳管開通を促すためには、全体を均等に絞る作用だけでなく、乳管集約部の中心深部方向の角度で、より深く集中的な圧迫を加えることが必要である。 When attached to the breast of a pregnant woman, the expansion and contraction of the inner diameter of the annulus is the expansion and contraction in the direction perpendicular to the axis of the breast. The "squeezing" action occurs. However, as mentioned above, in order to promote the opening of the duct, it is necessary not only to squeeze the whole duct evenly, but also to apply deeper and concentrated compression at an angle toward the center of the duct aggregation portion. ..

人工筋肉リングの内径、及び、人工筋肉リングから乳管集約部の中心深部の方向への角度は、使用者の***の大きさや形状、状態により適宜設定され得るが、少なくとも、収縮時に圧迫を加えるべき方向は、人工筋肉リングの円環面の軸線上の後方側(使用者の背後方向)の1点に向けた方向となる。 The inner diameter of the artificial muscle ring and the angle from the artificial muscle ring toward the central deep part of the ductal aggregation part can be appropriately set depending on the size, shape, and condition of the user's breast, but at least, compression is applied during contraction. The power direction is the direction toward one point on the posterior side (behind the user) on the axis of the annular surface of the artificial muscle ring.

本発明における軟突起は、人工筋肉リングの収縮によって助産師の手指による乳管開通・乳汁分泌促進の手技と同様の効果的な圧迫刺激を乳管集約部、特に、その中心深部に加えられるように、手指の代替として、手指先に近い柔らかさの独立したゴム塊を装着したものである。 The soft process in the present invention is such that the contraction of the artificial muscle ring applies an effective compression stimulus similar to the procedure of opening the duct and promoting milk secretion by the midwife's finger to the duct concentrating part, particularly to the deep center thereof. In addition, as an alternative to the fingers, an independent rubber block with a softness close to that of the fingertips is attached.

また、本発明は、人工筋肉リングへの軟突起の取り付け方法に格別の特徴を有する。マッキベン式人工筋肉リングの断面形状は、その構造上、弾性体チューブの拡張時には略円形となる。一方、断面略カマボコ型の軟突起は、略平面の底面から略円筒側面の一部を成す湾曲した突起部分が立ち上がる形状であり、前記底面の一部が人工筋肉リングの内径側面の一部に取り付けられる。 Further, the present invention has a special feature in the method of attaching the soft protrusion to the artificial muscle ring. Due to its structure, the cross-sectional shape of the Macchiben artificial muscle ring becomes substantially circular when the elastic tube is expanded. On the other hand, the soft protrusion having a substantially camboko-shaped cross section has a shape in which a curved protrusion portion forming a part of a substantially cylindrical side surface rises from the bottom surface of a substantially flat surface, and a part of the bottom surface is a part of the inner diameter side surface of the artificial muscle ring. It is attached.

もし、軟突起の底面の中央部を人工筋肉リングの内径側面の中央部に取り付けた場合は、人工筋肉リングの内径の拡縮に押された軟突起は、単に人工筋肉リングの円環面上を中心に向けて押し出されるので、その先端は乳管集約部の中心深部の方向には向かわず、適切な圧迫を得られない。 If the central part of the bottom surface of the artificial muscle ring is attached to the central part of the inner diameter side surface of the artificial muscle ring, the soft protrusion pushed by the expansion and contraction of the inner diameter of the artificial muscle ring is simply on the torus surface of the artificial muscle ring. Since it is extruded toward the center, its tip does not point toward the deep center of the torus, and proper compression cannot be obtained.

一方、軟突起の底面の中央部を、人工筋肉リングの内径側面の***寄り側に、あらかじめその先端が乳管集約部の中心深部の方向に向くように取り付ければ、適切な方向への圧迫が得られる。しかしこの場合、圧迫力が作用する軟突起の突起部分は常に同一の部分が***の皮膚の同一の位置に接触することになり、産後の***乳輪のデリケートな皮膚への負担となるという問題がある。 On the other hand, if the central part of the bottom surface of the soft process is attached to the side of the inner diameter of the artificial muscle ring toward the breast in advance so that the tip of the artificial muscle ring faces toward the deep center of the duct consolidating part, compression in an appropriate direction can be applied. can get. However, in this case, the protruding part of the soft protrusion on which the compression force acts always comes into contact with the same part of the breast skin at the same position, which causes a burden on the delicate skin of the breast areola after childbirth. There is.

助産師による乳管開通操作では、助産師は、皮膚の同一の位置に単純に圧迫を加えて傷つけないように、伸縮する皮膚に沿って微妙に手指先面を添わせて順次圧迫を加えるというテクニックが用いられている。本発明は、軟突起を略カマボコ型とし、底面の***寄り側の接合部を、前記人工筋肉リングの内周側面の***寄り側の位置に接合することにより、かかる助産師の手技を模倣可能としている。 In a duct opening operation by a midwife, the midwife simply applies pressure to the same position on the skin so that it does not hurt, and the pressure is applied sequentially along the stretchable skin with the fingertips slightly aligned. The technique is used. INDUSTRIAL APPLICABILITY The present invention can imitate such a midwife's procedure by forming the soft protrusion into a substantially kamaboko type and joining the joint portion on the bottom surface closer to the breast to the position on the inner peripheral side surface of the artificial muscle ring on the side closer to the breast. It is supposed to be.

軟突起を略カマボコ型とすることで、皮膚を圧迫する突起を、円筒外側面の一部をなすカマボコ天面の曲面として構成している。また、軟突起と人工筋肉リングとの接合部を、軟突起の底面の***寄り側と人工筋肉リングの内周側面の***寄り側とを接合してオフセットさせているため、軟突起は接合部を軸に回転座屈するように可動する。軟突起が乳管集約部の中心深部の方向に向かって回転する際の最大角度は、使用者の***の大きさや形状により適宜設定し得るが、一般的な褥婦の***を想定した場合、人工筋肉リングの円環面から***側、すなわち使用者の背後方向に向けて30~45°とし、望ましくは35~40°が好適である。 By making the soft protrusions substantially semi-cylindrical, the protrusions that press against the skin are configured as the curved surface of the top surface of the semi-cylindrical surface that forms part of the outer surface of the cylinder. In addition, since the joint between the soft process and the artificial muscle ring is offset by joining the bottom surface of the soft process near the breast and the inner peripheral side surface of the artificial muscle ring near the breast, the soft process is the joint. It moves so as to rotate and buckle around the axis. The maximum angle at which the soft protrusion rotates toward the deep center of the ductal agglomeration can be set appropriately depending on the size and shape of the user's breast, but when assuming a general breast of a decubitus woman, The temperature is 30 to 45 °, preferably 35 to 40 °, from the torus surface of the artificial muscle ring toward the breast side, that is, toward the back of the user.

***に装着した際に、軟突起はカマボコ型天面の***寄り側のみで***に接触するが、人工筋肉リングが加圧されて拡張するにつれて円環面上を中心に向けて押し出された軟突起は、***側にオフセットした接合部を軸に徐々に座屈するように回転する。そして、人工筋肉リングの最大拡張時には、軟突起の先端が***の乳管集約部の中心深部の方向に向いて圧迫を加える。この間、軟突起は徐々に回転しながら圧迫で伸縮する皮膚に順次接触していくので、皮膚の同一の位置に単純に圧迫を加えて傷つけないという、助産師の手技に近い効果が得られるのである。 When attached to the breast, the soft process contacts the breast only on the side of the top surface of the torus that is closer to the breast, but as the artificial muscle ring is pressurized and expanded, it is extruded toward the center on the torus surface. The protrusion rotates so as to gradually buckle around the joint offset to the breast side. Then, at the time of maximum expansion of the artificial muscle ring, the tip of the soft process is directed toward the deep center of the ductal aggregation part of the breast to apply compression. During this time, the soft protrusions gradually rotate and gradually come into contact with the skin that expands and contracts due to pressure, so the effect of simply applying pressure to the same position on the skin and not damaging it can be obtained, which is similar to the midwife's procedure. be.

(パッド)
パッドは、***に密着してこれを覆う略円錐台側面形状の布体である。その上面円周に沿って人工筋肉リングを設けることで、拡縮により軟突起の位置がずれないように固定するとともに、乳汁分泌促進器を乳帯(産後用ブラジャー)等に実装して***に密着固定することで、褥婦が姿勢を問わず手軽に使用できるようにすることができる。
(pad)
The pad is a cloth body in the shape of a substantially truncated cone that adheres to and covers the breast. By providing an artificial muscle ring along the circumference of the upper surface, the position of the soft process is fixed so that it does not shift due to expansion and contraction, and a milk secretion promoter is mounted on a breast band (postpartum brassiere) etc. to adhere to the breast. By fixing it, it is possible to make it easy for the female to use it regardless of the posture.

(ケース)
ケースは、中央に乳頭部を露出させるための孔を有する円盤の外周に側壁を設けてなる略円盤型の硬質の部材である。ケースは内装した人工筋肉リングの拡張によって変形しない硬度を有するなら特に素材は限定されないが、軽量なプラスティック製が好適である。人工筋肉リングの断面径の拡張時には、前記ケースの側壁の内側面によって円環の外側方向への拡張が規制され、内側方向にのみ拡張可能となるため、人工筋肉リングの内径の収縮を増強するように作用する。
(Case)
The case is a substantially disk-shaped hard member having a side wall provided on the outer periphery of a disk having a hole for exposing the papilla in the center. The material of the case is not particularly limited as long as it has a hardness that does not deform due to the expansion of the built-in artificial muscle ring, but a lightweight plastic case is preferable. When the cross-sectional diameter of the artificial muscle ring is expanded, the inner surface of the side wall of the case restricts the expansion of the annulus in the outward direction and expands only in the medial direction, thereby enhancing the contraction of the inner diameter of the artificial muscle ring. It works like that.

(その他の構成)
人工筋肉リングを拡縮させる機構は人工筋肉の方式・種類により適宜選択される。マッキベン式人工筋肉である場合は、圧縮ガスの弾性体チューブへの加減圧により駆動できるため、たとえば、人工筋肉リングのT字コネクタを、加減圧タイミング調整器を介して、圧力調整器付き圧縮ガスボンベにホースで接続することでシステムとして完結できる。
(Other configurations)
The mechanism for expanding and contracting the artificial muscle ring is appropriately selected depending on the method and type of the artificial muscle. In the case of a Macchiben type artificial muscle, it can be driven by pressurizing or depressurizing the compressed gas to the elastic tube. It can be completed as a system by connecting it with a hose.

以上の構成により、本発明に係る乳汁分泌促進器は以下のような、従来技術にない作用効果を奏する。
1)乳管集約部の中心深部に選択的に適切な圧迫を加えることができるため、有効性の高い乳管開通操作、乳汁分泌促進を行える。
2)人工筋肉リング、軟突起、パッドという直接身体に装着する構成が、いずれも人体親和性の高い部材であり、その動作も助産師の手技を模倣可能としているため、使用上の安全性が高く違和感も小さい。
3)人工筋肉リング、軟突起、パッドという直接身体に装着する構成が、いずれも軽量であるため、使用中の使用者の姿勢や動作への制限が小さく、家庭でも手軽に使用でき、効率的に効果を得られる。
4)構造が簡易で部材も低コストであるため、普及させやすい。
With the above configuration, the milk secretion promoter according to the present invention has the following effects and effects not found in the prior art.
1) Since an appropriate compression can be selectively applied to the deep center of the duct consolidating portion, a highly effective duct opening operation and milk secretion promotion can be performed.
2) The artificial muscle ring, soft protrusions, and pads that are directly attached to the body are all highly compatible with the human body, and their movements can imitate the midwife's procedure, so they are safe to use. It is expensive and has little discomfort.
3) Since the artificial muscle ring, soft protrusions, and pads that are directly attached to the body are all lightweight, there are few restrictions on the posture and movement of the user during use, and they can be easily used at home and are efficient. The effect can be obtained.
4) Since the structure is simple and the members are low cost, it is easy to spread.

以下、本発明の実施形態を図面に基づいて説明する。図3は、本発明の一つの実施形態に係る一対の乳汁分泌促進器1と、装着時にその上から妊婦用ブラジャーBに適用した状態を示す。一対の乳汁分泌促進器1にはそれぞれホース16を通じて圧縮炭酸ガスを供給し、間欠的に加減圧する。外部機器である小型圧縮炭酸ガスボンベ、圧力調整器、加減圧タイミング調整器は省略しているが、出願人の試作品では、内蔵する電磁弁(SMC株式会社製SYJ514-1MZ-01)の動作時間と開閉時間を2つのタイマー(オムロン株式会社製H3CR-A)を用いて設定できる加減圧タイミング調整器を製作して用いている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 3 shows a pair of milk secretion promoters 1 according to one embodiment of the present invention, and a state in which they are applied to a pregnant woman's brassiere B from above when worn. Compressed carbon dioxide gas is supplied to each of the pair of milk secretion promoters 1 through a hose 16, and the pressure is intermittently increased or decreased. The small compressed carbon dioxide cylinder, pressure regulator, and pressurization / depressurization timing regulator, which are external devices, are omitted, but in the prototype of the applicant, the operating time of the built-in solenoid valve (SYJ514-1MZ-01 manufactured by SMC Corporation). An acceleration / depressurization timing adjuster that can set the opening / closing time using two timers (H3CR-A manufactured by OMRON Corporation) is manufactured and used.

圧縮炭酸ガスによる加減圧のリズムと継続時間は乳児の吸啜を理想としており、助産師の手技のリズムもこれに準じている。リズムは短周期(0.2~0.5秒毎)と長周期があり、哺乳開始直後の1分間程度が短周期で、その後は約1秒間の吸啜(圧迫)、約1秒間の間歇という長周期となる。継続時間は、良好に哺乳している新生児は10~20分以内で必要量を飲み取るため、1回当りの継続時間もこれに準じ、新生児の吸啜や助産師の手技を模倣することが好適である。これらの加減圧のリズムや継続期間は加減圧タイミング調整器により任意に設定・制御可能である。 The rhythm and duration of compression and depressurization by compressed carbon dioxide is ideal for sucking infants, and the rhythm of the midwife's procedure follows this. The rhythm has a short cycle (every 0.2 to 0.5 seconds) and a long cycle, with a short cycle of about 1 minute immediately after the start of feeding, then sucking (compression) for about 1 second, and intermittent for about 1 second. It becomes a long cycle. The duration is within 10 to 20 minutes for a well-fed newborn to swallow the required amount, so the duration per dose can be similar to this, mimicking newborn sucking and midwifery procedures. Suitable. The rhythm and duration of these pressurization and depressurization can be arbitrarily set and controlled by the pressurization / depressurization timing adjuster.

乳汁分泌促進器1は本体部10とパッド20とからなり、本体部10は外部機器とホース16で接続され、圧縮炭酸ガスを供給される。図4はパッド20を閉じた状態の乳汁分泌促進器1の単体の外側を示す斜視図、図5はパッド20を開放した状態の乳汁分泌促進器1の単体を内側(***に触れる側)から見た平面図である。パッド20は内面側に滑り止め加工を施した通気性の高いメッシュシートであり、開放状態では略扇形で、丸めて略扇形の両端を面ファスナー(図示せず)で固定することにより、***に密着し乳頭部分を露出させる円錐台側面形状とできる。 The milk secretion promoter 1 includes a main body 10 and a pad 20, and the main body 10 is connected to an external device by a hose 16 to supply compressed carbon dioxide gas. FIG. 4 is a perspective view showing the outside of the milk secretion promoter 1 with the pad 20 closed, and FIG. 5 shows the milk secretion promoter 1 with the pad 20 open from the inside (the side touching the breast). It is a plan view as seen. The pad 20 is a highly breathable mesh sheet with anti-slip processing on the inner surface side, and is substantially fan-shaped in the open state. It can be a truncated cone side surface shape that is in close contact and exposes the nipple part.

図6は、人工筋肉リング12が収縮状態の場合の本体部10の単体を内側(***に触れる側)から見た平面図であり、図7は、同拡張状態の場合の平面図である。本体部10は中央に孔11aを有する円盤の外周に側壁11bを設けてなる略円盤型のケース11と、当該ケース11内に内装された人工筋肉リング12と、人工筋肉リング12の内周側面に接合部13により等間隔で取り付けられた3つの軟突起14とからなる。軟突起14の数を3つとしているのは、助産師の3指法の手技を模倣するためであるが、軟突起14の数は2つ、あるいは4つとしてもよい。 FIG. 6 is a plan view of a single body of the main body 10 when the artificial muscle ring 12 is in the contracted state from the inside (the side touching the breast), and FIG. 7 is a plan view of the main body 10 in the expanded state. The main body 10 has a substantially disk-shaped case 11 having a side wall 11b provided on the outer periphery of a disk having a hole 11a in the center, an artificial muscle ring 12 built in the case 11, and an inner peripheral side surface of the artificial muscle ring 12. It is composed of three soft protrusions 14 attached to the joint portion 13 at equal intervals. The number of soft protrusions 14 is set to 3 in order to imitate the midwife's three-fingering procedure, but the number of soft protrusions 14 may be two or four.

出願人の製作した本実施形態に係る乳汁分泌促進器1の人工筋肉リング12は、内径7mm、外径9mm、全長約17cmのナイロンメッシュスリーブ内に内径6mm、外径6.3mm、全長約17cmのウレタンゴムチューブを内装した直線状のマッキベン式人工筋肉を、ガス吸排管15aを備えたT字コネクタ15でリング状に接続して円環状に形成している。 The artificial muscle ring 12 of the milk secretion promoter 1 according to the present embodiment manufactured by the applicant has an inner diameter of 6 mm, an outer diameter of 6.3 mm, and a total length of about 17 cm in a nylon mesh sleeve having an inner diameter of 7 mm, an outer diameter of 9 mm, and a total length of about 17 cm. A linear Macchiben-type artificial muscle containing a urethane rubber tube is connected in a ring shape by a T-shaped connector 15 provided with a gas suction / exhaust pipe 15a to form an annular shape.

軟突起14はウレタンゴム塊を短い略カマボコ型に形成しており、その大きさは概ね女性(助産師)の手指先と同程度としている。具体的には、略カマボコ型の底面14aから湾曲した天面14b頂部までの高さ、底面14aの幅及び長さを、いずれも1cm程度としている。 The soft protrusion 14 forms a urethane rubber lump in a short, substantially semi-cylindrical shape, and its size is approximately the same as that of a female (midwife) fingertip. Specifically, the height from the bottom surface 14a of the substantially semi-cylindrical shape to the top of the curved top surface 14b, and the width and length of the bottom surface 14a are all about 1 cm.

接合部13は、伸縮性に富むナイロン糸(テグス4号)を用いて、人工筋肉リング12の断面の最下部(***寄り側)から2mm程度の位置のナイロンメッシュスリーブに、軟突起14の略カマボコ型の略底面14aの最下部(***寄り側)を、軟突起14の幅一杯に渡り線状に縫い付けることで形成している。 The joint portion 13 uses a highly elastic nylon thread (Tegus No. 4) to form a nylon mesh sleeve located about 2 mm from the lowermost part (closer to the breast) of the cross section of the artificial muscle ring 12, and is an abbreviation for the soft protrusion 14. The lowermost part (closer to the breast) of the substantially bottom surface 14a of the Kamaboko type is sewn linearly over the entire width of the soft protrusion 14.

図8及び図9は、***に装着された状態の本体部10の断面模式図であり、それぞれ図6及び図7のA-A断面を表す。なお、パッド20は省略している。図8に示すように、収縮状態の人工筋肉リング12の断面は、ケース11の中で平たく畳まれた状態となっている。そのため、接合部13によって人工筋肉リング12に接合された軟突起14の天面14bは、概ね人工筋肉リング12の円環面の中心方向に向いており、***には天面14bの下部が接する形となる。 8 and 9 are schematic cross-sectional views of the main body 10 in a state of being attached to the breast, and show AA cross sections of FIGS. 6 and 7, respectively. The pad 20 is omitted. As shown in FIG. 8, the cross section of the contracted artificial muscle ring 12 is in a flatly folded state in the case 11. Therefore, the top surface 14b of the soft projection 14 joined to the artificial muscle ring 12 by the joint portion 13 is generally oriented toward the center of the torus surface of the artificial muscle ring 12, and the lower portion of the top surface 14b is in contact with the breast. It becomes a shape.

なお、拡張時の人工筋肉リング12は断面が円形となるが、収縮時に平たく畳まれた形状となるのは、マッキベン式人工筋肉に用いられる一般的な長尺のナイロンメッシュスリーブがロール状に巻き重ねられて流通しているため、巻き重ねにより折り畳み癖がついているからである。 The artificial muscle ring 12 at the time of expansion has a circular cross section, but the shape that is folded flat at the time of contraction is a roll of a general long nylon mesh sleeve used for the Macchiben type artificial muscle. This is because they are stacked and distributed, so they have a habit of folding due to stacking.

図9は人工筋肉リング12に圧縮炭酸ガスを印加した状態を示す。人工筋肉リング12は断面が円形に拡張するが、ケース11の側壁11bによって円環該側面の位置は規制されるため、円環内側面が内側方向に拡張して軟突起14を押す形となる。なお、出願人の製作した試作品では、ケース11に内装しない状態の人工筋肉リング12は、圧縮炭酸ガス0.2MPaの加圧により直径が拡張・全長が短縮することにより、円環内径が約1cm狭まり、ケース11に内装した状態では円環内径の縮小は約1.2cmとなった。 FIG. 9 shows a state in which compressed carbon dioxide gas is applied to the artificial muscle ring 12. The artificial muscle ring 12 expands in a circular cross section, but since the position of the side surface of the annulus is restricted by the side wall 11b of the case 11, the inner surface of the annulus expands inward and pushes the soft protrusion 14. .. In the prototype produced by the applicant, the artificial muscle ring 12 in a state not inside the case 11 has an inner diameter of about annulus due to the expansion of the diameter and the shortening of the total length by pressurizing the compressed carbon dioxide gas at 0.2 MPa. It was narrowed by 1 cm, and when it was installed in the case 11, the inner diameter of the annulus was reduced by about 1.2 cm.

ここで、軟突起14は人工筋肉リング12に接合部13で接合されているため、接合部13を回転軸として下方に向けて回転座屈し、乳管集約部Gの中心深部Dを圧迫する。この際、軟突起14が回転するため、略カマボコ型の天面14bは、その下部から上部に向けて順次***の皮膚に接触する形となり、皮膚の同一箇所を単純に圧迫して傷つけるおそれの小さい助産師の乳管開通操作の手技が模倣再現されるのである。 Here, since the soft protrusion 14 is joined to the artificial muscle ring 12 at the joint portion 13, it rotationally buckles downward with the joint portion 13 as the rotation axis and presses the central deep portion D of the duct consolidating portion G. At this time, since the soft protrusion 14 rotates, the substantially semi-cylindrical top surface 14b comes into contact with the breast skin sequentially from the lower part to the upper part, and there is a risk of simply pressing and damaging the same part of the skin. The procedure of opening the breast duct of a small midwife is imitated and reproduced.

(熟練助産師の手技と比較する動作試験)
出願人は試作品の乳汁分泌促進器1の人工筋肉リング12を圧縮炭酸ガスの加減圧により拡張収縮させて軟突起14が乳管集約部を圧迫する動作が、少なくとも熟練助産師の手技と同程度に適切・有効であることを確認するため動作試験を行った。
(Operation test to compare with the technique of a skilled midwife)
The applicant has at least the same procedure as a skilled midwife in that the artificial muscle ring 12 of the milk secretion promoter 1 of the prototype is expanded and contracted by pressurizing and depressurizing the compressed carbon dioxide gas, and the soft protrusion 14 presses the duct consolidating part. An operation test was conducted to confirm that it was appropriate and effective.

動作試験は、人体の個体差による誤差を排除するべく、産科医師や助産師等の手技訓練に使用されている***を再現した搾乳トレーニングモデル(株式会社エムシーピー製MC009)を使用した。また、褥婦がどのような姿勢でも乳管集約部の深部中央を適切に圧迫できることを確認するため、褥婦の胴部を再現した株式会社高研製「妊婦腹部触診モデル1型」の両***に搾乳トレーニングモデルを取り付けた褥婦モデルを製作し、これに産後用ブラジャー(西松屋マタニティー乳帯Lサイズ)を使用して乳汁分泌促進器を装着し、次の条件で動作試験を行った。
(1)乳汁分泌促進器による動作と熟練助産師の手技を、それぞれ乳児の長周期の吸啜を模擬した1秒間圧迫動作・1秒間歇のサイクルを5サイクル、模擬乳汁の「初乳」・「成乳」別に各10回づつ実施した。なお、乳汁分泌促進器では、人工筋肉リングに圧縮炭酸ガス0.2MPaを加圧した。
(2)圧迫により漏出した模擬乳汁の採取量を比較。
(3)圧迫の際は、圧迫を邪魔せず、かつもれなく模擬乳汁が採取できるように柔らかい薄手のシリコン製乳首カバー(ビジョン株式会社 乳頭保護器 ソフトタイプLサイズ)を取り付けた。
In the operation test, a milking training model (MC009 manufactured by MCP Co., Ltd.) that reproduces the breast used for the procedure training of obstetricians and midwives was used in order to eliminate errors due to individual differences in the human body. In addition, in order to confirm that the decubitus can properly press the deep center of the duct aggregation part in any posture, both breasts of "Pregnant Woman Abdominal Tactile Model Type 1" manufactured by Koken Co., Ltd. that reproduces the decubitus body. A decubitus model with a milking training model attached was produced, and a milk secretion promoter was attached to this using a postpartum brassiere (Nishimatsuya Maternity Duct L size), and an operation test was conducted under the following conditions.
(1) The operation by the milk secretion promoter and the technique of a skilled midwife, each of which is a 1-second compression operation that simulates a long-cycle sucking of an infant. It was carried out 10 times for each "mature milk". In the milk secretion promoter, compressed carbon dioxide gas 0.2 MPa was applied to the artificial muscle ring.
(2) Compare the amount of simulated milk leaked due to compression.
(3) At the time of compression, a soft and thin silicone nipple cover (Vision Co., Ltd. nipple protector soft type L size) was attached so that the simulated milk could be collected without disturbing the compression.

動作試験の結果は表1のとおりであり、初乳の場合、熟練助産師の手技1回での漏出量は平均0.03ml、5回動作では0.23mlであったのに対し、乳汁分泌促進器の1回動作での漏出量は平均0.02ml、5回動作では0.22mlとなった。成乳の場合、熟練助産師の手技1回での漏出量は平均0.13ml、5回動作では0.88mlであったのに対し乳汁分泌促進器の1回動作での漏出量は平均0.13ml、5回動作では0.99mlとなった。すなわち、初乳・成乳に関わらず、乳汁分泌促進器は熟練助産師の手技とほぼ同等の乳汁を漏出させることが確認された。また、いずれの場合も搾乳トレーニングモデルの皮膚に圧痕等のトラブルは生じることはなかった。 The results of the operation test are shown in Table 1. In the case of the first milk, the average amount of leakage in one procedure of a skilled midwife was 0.03 ml, while that in the case of five operations was 0.23 ml, whereas lactation was secreted. The amount of leakage of the accelerator in one operation was 0.02 ml on average, and 0.22 ml in five operations. In the case of mature milk, the average amount of leakage in one procedure by a skilled midwife was 0.13 ml, while the average amount of leakage in one operation of the milk secretion promoter was 0.88 ml in five operations. It was .13 ml and 0.99 ml in 5 operations. That is, it was confirmed that the lactation promoter leaks milk almost equivalent to the procedure of a skilled midwife, regardless of whether it is mature milk or mature milk. In any case, no trouble such as indentation occurred on the skin of the milking training model.

(姿勢の違いによる動作試験)
生活の中での乳汁分泌促進器の実際の使用においては、上半身を立ち姿勢の場合と仰臥位の寝姿勢が想定される。そのため、姿勢の違いによる作用効果の差異を検証するべく、前述の褥婦モデルに乳分泌促進器を装着し、同じ条件で縦置き(直立)と横置き(仰臥)それぞれ5回づつ試行して模擬乳汁の採取量を比較した。動作試験の結果は表2のとおりであり、縦置き・横置きの間で採取量にほぼ相違はなく、乳汁分泌促進器の作用効果は使用者の姿勢を問わず有効であることが確認された。

(Motion test due to different posture)
In the actual use of the lactation promoter in daily life, it is assumed that the upper body is in a standing position and the supine position is in a lying position. Therefore, in order to verify the difference in action and effect due to the difference in posture, the lactation promoter was attached to the above-mentioned decubitus model, and under the same conditions, vertical placement (upright) and horizontal placement (supine) were tried 5 times each. The amount of simulated milk collected was compared. The results of the operation test are shown in Table 2, and it was confirmed that there was almost no difference in the amount collected between vertical and horizontal placement, and that the action and effect of the milk secretion promoter was effective regardless of the posture of the user. rice field.

以上の動作試験から、本発明に係る乳汁分泌促進器は、使用者の姿勢を問わず、熟練助産師の手技に遜色のない効果を発揮することが確認された。人工筋肉リングは***の適切な位置に持続的に密着固定させることが重要であるが、***の大きさや形状に沿わせることができ、肌に張り付く滑り止め加工を施したパッドを設けているため、***への装着後に乳帯(ブラジャー)で押さえることにより人工筋肉リングのずれを防止できることも確認された。 From the above operation tests, it was confirmed that the milk secretion promoter according to the present invention exerts an effect comparable to that of a skilled midwife regardless of the posture of the user. It is important that the artificial muscle ring is continuously adhered and fixed in the proper position of the breast, but because it can fit the size and shape of the breast and has a non-slip pad that sticks to the skin. It was also confirmed that the artificial muscle ring can be prevented from slipping by pressing it with a breast band (bra) after it is attached to the breast.

以上、本発明に係る乳汁分泌促進器の具体的な構成について説明したが、本発明は上記実施形態に限定されるものではなく、本発明の技術的思想の範囲内において改良又は変更が可能であり、それらは本発明の技術的範囲に属するものである。 Although the specific configuration of the milk secretion promoter according to the present invention has been described above, the present invention is not limited to the above embodiment, and can be improved or modified within the scope of the technical idea of the present invention. Yes, they belong to the technical scope of the invention.

本発明に係る乳汁分泌促進器によれば、熟練助産師の手技にも遜色のない乳管開通操作を、褥婦が自ら手軽に実施可能になる。装置は簡易かつ軽量・コンパクトな構造で低コストで製造できるので、産科医院等の医療機関はもとより家庭にも普及させやすく、母乳保育の促進に貢献し得るものである。 According to the milk secretion promoter according to the present invention, a milk duct opening operation comparable to that of a skilled midwife can be easily performed by a decubitus woman. Since the device has a simple, lightweight and compact structure and can be manufactured at low cost, it can be easily spread not only to medical institutions such as obstetric clinics but also to homes, and can contribute to the promotion of breastfeeding.
