Description

Synchronous suction device for breast pump and breast pump containing the same

Technical field

The utility model belongs to a device for assisting a woman to derive milk by using a negative pressure, and relates to a pumping device which forms an intermittent negative pressure in a cup by a gas pump through a synchronous suction device and acts on the maternal breast, and the milk is discharged and stored in the container. The device, that is, a flat synchronous suction device suitable for hiding in a lactating woman and a breast pump for carrying it, that is, a stealth breast pump. Background technique

The cup of the existing breast pump, the deformed part of the cylinder and the bottle system are integrated, and the cylinder deforming part generates a negative pressure in the cup, sucks the milk of the breast, helps the milk to be secreted, and is supported by the cylinder. The deformed part separates the milk and collects the milk in the bottle.

The problems are as follows: 1. The female body in use is bare, inconvenient to use in public places, need to set up a special or independent room. · Second, the milk is sucked in, need to be assisted by the hand, hold the bottle by both hands, and let The cup is pressed against the breast; 3. The cup is in the form of a flared upwardly upwards to accommodate the bottom-up contact with the breast, and the subsequent milk can flow down the mouth and enter through the milk channel. The bottle, the structure makes the shape of the product reveal, and is not easy to conceal; these problems will bring a lot of inconvenience and trouble to the use of professional women in lactation.

To this end, many foreign manufacturers have made improvements, they proposed the use of a sheath, the sheath has a through hole at the position corresponding to the breast, the cup is placed in the sheath, and the sheath is placed on the chest breast and Fixed, but the lower half of the cup is protruding from the deformed part of the cylinder, and the connected bottles are suspended. These schemes try to make the device do not need the assistance of the hand in sucking the milk, so that they can free their hands. In the process, you can do things like reading.

However, the cup, the cylindrical deforming member and the bottle are hung on the sheath, and the cup is mainly suspended by the sheath. In use, the protruding portion and the bottle are prone to the force of disengaging the cup from the breast due to the long arm. Make the cup and the breast can not fit, so that the negative pressure can not fully act on the breast, Therefore, in use, it is sometimes necessary to lift the cup by hand and make appropriate position adjustment; further, the cup, the cylinder deforming member and the bottle are hung on the breast, and no matter whether the cup and the breast are attached, it cannot be concealed. It is difficult to solve the problem of naked body by sucking up the milk, and its use is still very limited.

Thus, when the air pump is pumping, the opening of the cusp is closed and closed, and then a negative pressure is formed in the air chamber, and when the negative pressure reaches a certain size, the disc-shaped diaphragm will be reversed, and the protruding portion will protrude in the reverse direction. The air chamber space becomes smaller and the liquid flow room becomes larger, Yes, a negative pressure will be generated in the flow chamber, and the negative pressure is applied to the breast through the cup, and the sucked milk flows from the top to the bottom and is temporarily stored in the space around the liquid outlet below the liquid flow room. When the air pump releases air, the air chamber quickly returns to normal pressure, the disc-shaped diaphragm recovers its shape, and the cusps open the opening, so that the space of the liquid flow chamber becomes smaller, the air pressure becomes normal pressure, and thus, temporarily stored in the liquid flow The milk under the chamber will quickly flow into the milk collection container, and the entire milking process will not return the milk juice into the air chamber, which will not affect the normal operation of the air pump.

The synchronized suction device of the breast pump thus obtained has an overall volume as small as possible, and the shape is as flat and smooth as possible to fit between the left and right breasts of the female chest; meanwhile, since the dish-shaped diaphragm can be turned over, The protruding portion protrudes in the reverse direction, which can increase the space of the liquid flow room in an instant, so that a large negative pressure can still be obtained in the space, which satisfies the need of sucking milk.

Therefore, the breast pump used in the present invention can be realized by the following solutions: a breast pump for carrying, including a cup, an air pump and a milk collecting container, characterized in that it further comprises the above-mentioned synchronous suction device; a hard plastic cover and a soft plastic bottom cover, the cover and the bottom cover are curved curved surfaces, and the sleeves are formed to form a breast pump chamber, and the cover and the bottom are bonded to the edge; the cup is The milking mouth is formed at the lowest part of the milking chamber; the bottom of the bottom is also provided with a through hole; the milk collecting container is a milk bag, and the check valve of the milk bag is equipped with a one-way valve; the mouth of the air pump and the milk of the cup The mouth of the mouth and the milk bag are respectively connected to the air flow port, the liquid inlet port and the liquid outlet port of the synchronous suction device through a hose.

In the above solution, the cup is provided with a plurality of anti-blocking bumps which are offset from each other in the cavity of the human breast.

In the above solution, the cup and the synchronous suction device can be concealed in a resilient bra made of a flexible material, and the bra has an elastic portion between the left and right breasts, and the elastic portion is sewn with a zipper or magic. A clothing accessory that can be tightened, etc., has a substrate close to the human body.

In this way, the air pump and the milk bag can be hung on the waist cuff or hidden in the suit, and the cup and the synchronous suction device and the connecting hose can be hidden in the concealed bra, and the hose connected to the synchronous suction device can be It is taken out from the lower edge of the bra, so that the breast pump can be made to be non-exposed and not exposed during use. The breast pump thus obtained has the characteristics of a curved curved surface matching the cup, the bra and the breast, and the cup has been separated from the synchronous suction device and the bottle, so that the bra can be used to fix the cup to make it relatively stable. There is no need to tighten and adjust its position from time to time.

The use of the breast pump has the characteristics of concealment and largely avoids the influence of the use environment and the place of use. At the same time, the breast milk can be dispensed with the burden of the hands during the process of sucking the milk, and thus is particularly suitable for the use of professional women during lactation, thereby They bring great convenience.

In addition, the breast pump of the present invention prevents the breast nipple from being blocked by the nipple when it is stretched and contacts the nipple when it is stretched, thereby preventing the milk from being ejected; further, the bottom of the cup is blocked. The contact with the breast is a flexible fit of a large area, and the softer and more comfortable effect can be used, and the bottom stick can also prevent the milk in the cup from sticking to the breast during use. .

The present invention will be specifically described below in conjunction with the accompanying drawings:

Referring to Figures 1 and 2, the synchronous suction device 1 of the present breast pump presents a flat ellipsoid. The ellipsoid is formed by two hollow casings 11 which are sandwiched by two casings 11 in a nip between them and divide the inner cavity into two wedge-shaped spaces. , among them, One space serves as the air chamber 15, and the other space serves as the liquid flow chamber 14. An air flow port 111 is formed on the air chamber 15, a liquid discharge port 132 is formed at the lower end of the liquid flow room 111, and two liquid inlet ports 131 are opened on the side of the liquid flow room. The disc-shaped diaphragm 12 has a normally open jaw cusp 141. The cusp 141 has an opening under normal pressure and has an opening that can communicate with the plenum 15 and the flow chamber 14, and the cusp 141 is under negative pressure. The lower state is closed and the opening is closed to isolate the air chamber 15 from the flow chamber 14. In addition, under normal pressure, the disc-shaped diaphragm 12 is located below the nip; under the action of the negative pressure, the disc-shaped diaphragm 12 is turned over and is above the nip; thus, the volume of the synchronous suction device 1 can be as small as possible, so that It can be hidden on the body, and at the same time, the rotation of the dish-shaped diaphragm 12 is spatially guaranteed, and sufficient space for the flow chamber 14 is ensured.

Referring to Fig. 3 - Fig. 5, the breast pump used with the portable body includes a cup 2, a synchronous suction device 1, a milk bag 3, a pump 4 and a bra 5; the cup 2 is made of a hard plastic cover 21 and is soft The base sticker 22 is formed by a bottom plate 22; the bottom sticker 22 is of a hemispherical shape, wherein a through hole 221 is opened therebetween, and a groove is formed around the bottom surface 22; a bottom portion of the cover 21 is provided with a milk outlet 211, and the cover 21 is opened by the cover 21 The edge enters the groove of the bottom sticker 22 to combine the two; the bottom sticker 22 can be attached to the breast and allows the nipple to protrude from the through hole 221, and the milk secreted by the breast can enter and accumulate in the cover 21 and the bottom chamber 22 in the chamber 23; the cover 21 is formed with anti-blocking bumps 212, which prevent the breast nipple from being blocked and blocked when the cover is closed, blocking the nipple orifice, preventing the milk from being sprayed out; The tea inlet 311 of 3 is also provided with a one-way valve 32; the bra 5 is made of a flexible material with elasticity, and the bra 5 has an elastic portion 51 between the left and right breasts, and the elastic portion is sewn with a zipper or magic.
