a breast pump

technical field

The invention relates to the technical field of breast pumping products, in particular to a breast pump.

Background technique

Modern science has proved that breast milk is the best nutritional food for babies. However, the busy work makes many professional women have no time to breastfeed in person. The emergence of breast pumps has solved the problem of breastfeeding for professional women. Breast milk can be sucked into a feeding bottle through a breast pump and stored in a refrigerator. When the mother is away, other people can assist in breastfeeding, and the baby can continue to enjoy breast milk. In addition to being convenient for professional women to breastfeed, breast pumps can also help mothers with flat and sunken nipples, underdeveloped breasts, and scarce milk to achieve the purpose of milk collection.

At present, the breast milk collector and the breast shield of existing breast pumps are usually designed as one body, and they need to be supported by hands when using, which makes it inconvenient to use. Another disadvantage of existing breast pumps is that milk is easy to remain in the breast shield, which affects breast pumping Effect.

Contents of the invention

The object of the present invention is to address the deficiencies of the prior art and provide a breast pump that does not need to be supported by hands and has no milk residue in the breast shield.

The present invention is achieved through the following technologies: a breast pump, comprising a breast milk collector, a suction source and a breast shield, the suction source is provided with an air vent and an air suction port, and the breast shield is provided with an air vent channel and breast milk The milk outlet is connected to the breast milk collector through the first hose, the breast milk collector is connected to the suction port of the suction source through the second hose, and the air leakage channel is connected to the suction source through the third hose. The exhaust port of the suction source mentioned above.

Wherein, the breastshield includes a shield body, the bottom of the shield body is flat, and the center of the bottom of the shield body protrudes outwards to provide a receiving portion.

Wherein, the chamber wall of the accommodating part is provided with an annular groove and several diversion grooves, the diversion grooves communicate with the annular groove respectively, and the annular groove communicates with the milk outlet and the Exhaust channel.

Wherein, the inner cavity of the breastshield is provided with a liner conforming to the shape of the breastshield, and the part of the liner located in the accommodating part is provided with an opening.

Wherein, the pad is provided with massage protrusions.

Wherein, the milk outlet is sleeved with a communication tube, and the other end of the communication tube is sleeved with the first hose.

Wherein, the suction source is an electric suction source.

The beneficial effect of the present invention is: put the breast shield of the present invention on the breasts, since the breast shield of the present invention is set separately from the breast milk collector, the breast shield can be placed directly in the underwear without the need for hand support to activate the suction source , the suction source first inhales, and the air pressure in the breast milk collector and breast shield becomes negative pressure. When the air pressure is lower than the internal pressure of the human breast, the milk is sucked out from the nipple into the breast shield, and then the suction source is deflated, and then sucked The pressure inside the breastshield increases instantly, while the pressure of the breast milk collector is still in a negative pressure state. Under the action of the pressure difference, the milk quickly flows from the breast shield to the breast milk collector through the first hose to achieve the effect of no milk residue.

detailed description

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

As shown in Figure 1-2, a breast pump includes a breast milk collector 1, a suction source 2 and a breast shield 3, the suction source 2 is provided with an air vent 4 and an air suction port 5, and the breast shield 3 is provided with an air vent 6 and breast milk The outlet 7, the milk outlet 7 is connected to the breast milk collector 1 through the first hose 8, the breast milk collector 1 is connected to the suction port 5 of the suction source 2 through the second hose 9, and the air leakage channel 6 is connected to the suction source through the third hose 10 2's vent port 4. When in use, put the breast shield 3 on the breasts. Since the breast shield 3 of the present invention is separated from the breast milk collector 1, the breast shield 3 can be directly placed in the underwear without hand support. The source 2 first inhales, and the air pressure in the breast milk collector 1 and the breast shield 3 becomes negative pressure. When the air pressure is lower than the internal pressure of the human breast, the milk is sucked from the nipple into the breast shield 3, and then the suction source 2 is deflated. After the deflation, the pressure in the breast shield 3 increases instantly, while the pressure of the breast milk collector 1 is still in a negative pressure state. Under the action of the pressure difference, the milk flows from the breast shield 3 to the breast milk collector 1 rapidly through the first hose 8, There is no residue, and the suction source 2 continues to inhale and deflate. The suction source 2 repeatedly inhales and deflates in this way, and the milk can be sucked from the breast into the breast milk collector 1 one after another.

The breast shield 3 includes a shield body 11. The bottom of the shield body 11 is flat, and the flat design can effectively avoid the stretching of the breast caused by the curved surface design. To tighten the breast, it can effectively prevent the breast from stretching. The center of the bottom of the cover body 11 protrudes outwards to provide a receiving portion 12 for containing the nipple and the sucked milk.

The cavity wall of the receiving part 12 is provided with an annular groove 13 and several diversion grooves 14, the diversion grooves 14 are connected to the annular grooves 13 respectively, and the annular grooves 13 are connected to the milk outlet 7 and the air leakage channel 6, when the air leakage , the external air flows through the third hose 10, the vent channel 6, the annular groove 13, and the diversion groove 14, so that the pressure in the accommodation part 12 increases instantaneously, and the milk in the accommodation part 12 flows along the diversion groove 14 The annular groove 13, and then flows from the annular groove 13 to the milk outlet 7, which can effectively avoid the residue of milk.

The inner cavity of the breast shield 3 is provided with a liner 15 that matches the shape of the breast shield 3. The liner 15 is made of soft silica gel, which is elastic and can further prevent the breasts from stretching. The hardness is greater than that of the liner 15 at the receiving portion 12 , and the portion of the liner 15 located at the receiving portion 12 is provided with an opening 16 to facilitate the flow of milk from the opening 16 to the milk outlet 7 .

The liner 15 is provided with massage protrusions 17, which can massage the breasts to facilitate breast pumping.

The milk outlet 7 is sleeved with a connecting pipe 18. One end of the connecting pipe 18 has a large diameter and the other end has a small diameter. Connected to the milk outlet 7 , the small-diameter end of the communication pipe 18 is sleeved to the first hose 8 .

The suction source 2 is an electric suction source 2, which is convenient to use.

The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. limits.
