Description

本発明は、母乳搾乳器に関する。  The present invention relates to a breast pump.

母乳搾乳器の一形式として、実公昭５５−２８２７１号公報には両端を開口にした外筒と、両端を開口にすると共に一端開口を乳首に被せることのできるラッパ状に形成した内筒を備えた搾乳器が開示されている。この搾乳器では、外筒に内筒を気密に、かつ出入可能に嵌合し、外筒の一端開口から内筒のラッパ口を突出させている。そして、外筒の他端開口に内筒の外部から内部への空気の流入を阻止し、内筒の内部から外部への空気の流出を許容するチェック弁を設けている。  As one type of breast milking machine, Japanese Utility Model Publication No. 55-28271 is provided with an outer cylinder having both ends opened, and an inner cylinder formed in a trumpet shape having both ends opened and one end opening can be placed on the nipple. A breast pump is disclosed. In this breast pump, the inner cylinder is fitted into the outer cylinder in an airtight and detachable manner, and the trumpet mouth of the inner cylinder is protruded from one end opening of the outer cylinder. A check valve is provided at the other end opening of the outer cylinder to prevent the inflow of air from the outside to the inside of the inner cylinder and to allow the outflow of air from the inside of the inner cylinder to the outside.

上記した従来の搾乳器によれば、内筒のラッパ口を、乳首を覆うように***に圧接し、外筒を引っ張って内筒を外筒から引き出すと、内筒と外筒で区画される母乳貯留部の容積が拡大してここに負圧が発生する。この負圧が乳首に作用して母乳が母乳貯留部へ吸引される。内筒を外筒から引き出すとき、チェック弁は閉じて外部から母乳貯留部へ空気が流入するのを阻止するように作用する。  According to the conventional breast pump described above, when the trumpet mouth of the inner cylinder is pressed against the breast so as to cover the nipple and the outer cylinder is pulled to pull out the inner cylinder from the outer cylinder, the inner cylinder and the outer cylinder are partitioned. The volume of the breast milk reservoir increases and negative pressure is generated here. This negative pressure acts on the nipple to suck the breast milk into the breast milk reservoir. When the inner cylinder is pulled out from the outer cylinder, the check valve closes and acts to prevent air from flowing into the breast milk reservoir from the outside.

続いて、引き出した内筒を外筒に押し込むと、チェック弁が開き、母乳が母乳貯留部からチェック弁を通って外部へ排出される。  Subsequently, when the drawn inner cylinder is pushed into the outer cylinder, the check valve is opened, and the breast milk is discharged from the breast milk reservoir through the check valve to the outside.

The hollow protrusion 13c protrudes from the ring surface 13b to the opposite flange side 13a, and one main slit 13e is formed at the protrusion tip 13d. The hollow protrusion 13c constitutes a main check valve in the present invention.

図５に詳細を示すように、リング面１３ｂの一箇所に断面円形の空気導入部１３ｆが形成され、空気導入部１３ｆのキャップ内側端部に断面半円形の中空凸部１３ｇが一体成形され、空気導入部１３ｆの開口を覆蓋している。この中空凸部１３ｇの頂部に１本の副スリット１３ｈが形成されている。中空凸部１３ｇと空気導入部１３ｆはそれぞれ本発明における副チェック弁と主空気通路構成する。また、フランジ１３ａの裏面の２箇所に断面半円形の溝１３ｉが形成されている。この溝１３ｉは本発明における副空気通路を構成する。  As shown in detail in FIG. 5, an air introduction portion 13 f having a circular cross section is formed at one place on the ring surface 13 b, and a hollow convex portion 13 g having a semicircular cross section is integrally formed at the inner end of the cap of the air introduction portion 13 f. The opening of the air introduction part 13f is covered. One sub slit 13h is formed at the top of the hollow convex portion 13g. The hollow convex portion 13g and the air introduction portion 13f constitute a sub check valve and a main air passage in the present invention, respectively. In addition, grooves 13i having a semicircular cross section are formed at two locations on the back surface of the flange 13a. This groove 13i constitutes a sub air passage in the present invention.

本実施例に係る母乳搾乳器１０の構成は以上の通りであって、哺乳瓶１５に母乳を貯える場合、リングねじ蓋１２ｃを哺乳瓶１５の瓶口１５ａに締め付け、弁体１３のフランジ１３ａをリングねじ蓋１２ｃの裏面と哺乳瓶１５の瓶口１５ａの上端部で挟持し、弁体１３で外筒１２の他端開口１２ｂを副蓋する。このようにして母乳搾乳器１０を哺乳瓶１５に装着する。リングねじ蓋１２ｃを瓶口１５ａに締め付けても溝１３ｉによって哺乳瓶１５の内外が連通されるので、外気が哺乳瓶１５中に導入される。  The structure of the breast pump 10 according to the present embodiment is as described above. When breast milk is stored in the feeding bottle 15, the ring screw lid 12c is fastened to the bottle mouth 15a of the feeding bottle 15, and the flange 13a of the valve body 13 is attached. The ring screw lid 12c is sandwiched between the back surface and the upper end of the bottle mouth 15a of the baby bottle 15, and the valve body 13 covers the other end opening 12b of the outer cylinder 12 as a sub lid. In this way, the breast pump 10 is attached to the baby bottle 15. Even if the ring screw lid 12c is fastened to the bottle mouth 15a, the inside and outside of the baby bottle 15 communicate with each other by the groove 13i, so that the outside air is introduced into the baby bottle 15.

母乳搾乳器１０をリングねじ蓋１２ｃで哺乳瓶１５に装着したら、内筒１１のラッパ口１１ａを、乳首を覆うように***に圧接し、外筒１２を引っ張って内筒１１を外筒１２から引き出すと、内筒１１と外筒１２で区画される母乳貯留部１６の容積が拡大してここに負圧が発生する。この負圧が乳首に作用して母乳が母乳貯留部１６へ吸引される。  When the breast pump 10 is attached to the baby bottle 15 with the ring screw lid 12c, the trumpet mouth 11a of the inner cylinder 11 is pressed against the breast so as to cover the nipple, and the outer cylinder 12 is pulled to remove the inner cylinder 11 from the outer cylinder 12. When pulled out, the volume of the breast milk storage section 16 partitioned by the inner cylinder 11 and the outer cylinder 12 is expanded, and a negative pressure is generated here. This negative pressure acts on the nipple and sucks the breast milk into the breast milk reservoir 16.

内筒１１を外筒１２から引き出すとき、弁体１３の中空突起部１３ｃの突起先端１３ｄに形成した主スリット１３ｅは、軟質プラスチックゴムの弾力により閉じているので、主チェック弁である中空突起部１３ｄは哺乳瓶１５から母乳貯留部１６へ空気が流入するのを阻止するように作用する。また、中空凸部１３ｇの副スリット１３ｈも母乳貯留部１６の所定負圧以下のうちは軟質プラスチックゴムの弾力で閉じているので、副チェック弁である中空凸部１３ｇは哺乳瓶１５から空気導入部１３ｆを通って母乳貯留部１６へ空気が流入するのを阻止する。  When the inner cylinder 11 is pulled out from the outer cylinder 12, the main slit 13e formed at the protrusion tip 13d of the hollow protrusion 13c of the valve body 13 is closed by the elasticity of soft plastic rubber, so that the hollow protrusion that is the main check valve 13d acts to prevent air from flowing from the baby bottle 15 into the breast milk reservoir 16. Further, since the auxiliary slit 13h of the hollow convex portion 13g is also closed by the elasticity of the soft plastic rubber within the predetermined negative pressure of the breast milk storage portion 16, the hollow convex portion 13g as the auxiliary check valve is introduced into the air from the baby bottle 15. Air is prevented from flowing into the breast milk reservoir 16 through the portion 13f.

続いて、引き出した内筒１１を外筒１２に押し込むと、空気圧で主スリット１３ｅが開き、母乳が母乳貯留部１６から主スリット１３ｅを通って哺乳瓶１５に注入される。  Subsequently, when the drawn inner cylinder 11 is pushed into the outer cylinder 12, the main slit 13e is opened by air pressure, and breast milk is injected from the breast milk reservoir 16 through the main slit 13e into the baby bottle 15.

内筒１１を外筒１２から引き出したとき母乳貯留部１６に発生する負圧が所定負圧以上になると、中空凸部１３ｇの副スリット１３ｈが開き、空気導入部１３ｆを通って母乳貯留部１６へ外気が導入されるので、母乳貯留部１６の負圧が低減し、所定負圧を越えることはない。そのため、過大な負圧が***や乳首に作用して乳頭トラブルが発生するのを防止できる。  When the negative pressure generated in the breast milk storage part 16 when the inner cylinder 11 is pulled out from the outer cylinder 12 becomes a predetermined negative pressure or more, the sub slit 13h of the hollow convex part 13g opens, passes through the air introduction part 13f, and the breast milk storage part 16 Since outside air is introduced into the body, the negative pressure in the breast milk storage unit 16 is reduced and does not exceed the predetermined negative pressure. Therefore, it is possible to prevent nipple trouble from occurring due to excessive negative pressure acting on the breast and nipple.

また、本実施例に係る母乳搾乳器１０は、主チェック弁である中空突起部１３ｃと副チェック弁である中空凸部１３ｇが一体成形されているので、構造が簡素化され、母乳搾乳器１０の製造コストを低減できる。  In addition, the breast milking device 10 according to the present embodiment has a hollow projecting portion 13c that is a main check valve and a hollow convex portion 13g that is a sub-check valve, so that the structure is simplified and the breast milking device 10 is simplified. The manufacturing cost can be reduced.

なお、主チェック弁は母乳貯留部の負圧が高まればそれに比例して弁の気密性も高まるが、副チェック弁は弁の構造上所定負圧を越えると外気から空気を導入して圧力を一定圧に抑える効果がある。このため母乳貯留部の所定負圧は中空凸部の肉厚、硬度及びスリット長の各要素で決定される。製造時にこれらの各要素を調整して所定負圧が設定される。  If the negative pressure in the breast milk reservoir increases, the airtightness of the main check valve increases proportionally.However, the sub check valve introduces air from the outside air to increase the pressure when the negative pressure exceeds the specified negative pressure. There is an effect to keep the pressure constant. For this reason, the predetermined negative pressure of the breast milk storage part is determined by each element of the thickness, hardness, and slit length of the hollow convex part. A predetermined negative pressure is set by adjusting each of these elements during manufacturing.

また、本実施例に係る母乳搾乳器１０は一例として哺乳瓶１５に装着したが、例えば両端を開口にし、各開口の周囲にねじを形成した中間筒の一端にリングねじ蓋を締め付け、他端開口に特公平６−８１４０号に開示されたような樹脂フィルム製袋を装着し、この袋に母乳を貯えることも可能である。  In addition, the breast pump 10 according to the present embodiment is attached to the baby bottle 15 as an example. For example, the ring screw cap is fastened to one end of an intermediate tube having both ends opened and a screw is formed around each opening. It is also possible to mount a resin film bag as disclosed in Japanese Patent Publication No. 6-8140 in the opening and store breast milk in this bag.
