A kind of breast cup and with the breast pump of this breast cup
Technical field
This utility model belongs to a kind of air pressure that utilizes and helps puerpera's milk let-off gear(stand), specifically, is a kind of breast cup of improvement and with the breast pump of this breast cup.
Background technology
In prior art, milk sucking device, is generally comprised of negative pressure pump, three-way suction device and storage feeding bottle, wherein, by one end of three-way suction device be communicated with negative pressure pump, to form therein negative pressure; The other end forms or is fixed with a cup for enlarging gradually, and this cup is manufactured with the feature of the udder shape of coincideing, to dock with breast, milk is imported; , in one end again, is connected with storage feeding bottle meanwhile, the milk being imported by negative pressure is collected through storing feeding bottle.
Conventionally, cup is used rigid plastics to make, its advantage is easily to dock with breast, shortcoming is to be not easy and mammary areola laminating, although be to adopt suction function in breast, in inhaling newborn process, can not effectively to mammary areola, massage, on the contrary, due to the existence of negative pressure, easily form the direct pull of nipple, draw pain and puerpera is not felt well.
For addressing the above problem, there is producer to make cup with soft flexible plastic cement, a hard steady is set in the outside of soft flexible plastic cement.But this hard steady is only the effect of playing support, prevents from overturning in use procedure.In actual applications, cup remains single negative pressure extracting milk to the effect of puerpera's breast.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency and provides a kind of breast cup and with the breast pump of this breast cup, this breast pump can utilize gas pressure on puerpera's's age of sucking breast, use negative pressure extracting milk, simultaneously, by malleation, puerpera's breast is implemented to massage, promote cesarean lactation, and puerpera is felt comfortably cool, in the time of by positive/negative-pressure, effect reaches and imitates baby to inhale newborn effect.
Breast cup of the present utility model is realized by following scheme:
A breast cup, it is rendered as trumpet-shaped flexible inner layer structure, and its one end contacts with female breast, the other end is provided with the negative pressure hole being connected with the negative pressure gas circuit of air pump, distinguished, also comprise layer structure, between inside and outside layer structure, mutually seal and formation deformable space; In deformable space, be provided with a malleation hole being connected with the malleation gas circuit of air pump.
Breast pump of the present utility model is realized by following scheme:
A breast pump, comprises threeway parts, air pump, wherein, air pump has negative pressure gas circuit, distinguished, and breast pump also comprises above-mentioned breast cup, air pump also has malleation gas circuit, and malleation gas circuit is connected with the malleation hole of breast cup, and negative pressure gas circuit is connected with the negative pressure hole of breast cup.
The negative pressure producing in the inner space that breast cup of the present utility model can utilize air pump to surround at endothecium structure is drawn puerpera's milk, simultaneously, the malleation of also utilizing air pump to produce in deformable space, by endothecium structure, puerpera's breast is pushed or kneading, the sucking action of imitation baby's lip to puerperal breasts, be conducive to promote breast galactopoiesis, and puerpera is felt comfortably cool.
In above-mentioned breast pump, threeway parts are provided with the pipeline of a malleation gas circuit, and pipeline connects malleation gas circuit and malleation hole.
In above-mentioned breast cup, the surface, middle part of endothecium structure is provided with several protruding grains.

The specific embodiment
Below in conjunction with accompanying drawing, the embodiment of breast cup of the present utility model and breast pump is described in detail:
With reference to accompanying drawing, the breast cup 1 of present embodiment, there is trumpet-shaped endothecium structure 11 and layer structure 12, one end of flexible endothecium structure 11 is provided with negative pressure hole 15, the surface, middle part of endothecium structure 11 is provided with several protruding grains 17, rigid layer structure 12 is positioned at the periphery of endothecium structure 11, endothecium structure 11 and layer structure 12 seal mutually by trumpet-shaped opening end and necking end, and in they trumpet-shaped deformable spaces 13 of middle achievements, to meet the distortion of endothecium structure 11, deformable space 13 is provided with a malleation hole 14.Like this, the inner space 16 that can surround at endothecium structure 11 by negative pressure hole 15 produces negative pressure, so that draw the milk of nipple, can also in deformable space 13, produce malleation by malleation hole 14, make endothecium structure 11 produce deformation and push or kneading mammary areola and periphery thereof.
With reference to accompanying drawing, the breast pump of present embodiment, comprise threeway parts 2, air pump 3 and above-mentioned breast cup 1, wherein, air pump 3 has negative pressure gas circuit 32, malleation gas circuit 31, and threeway parts 2 are provided with a malleation pipeline 22 and a negative-pressure pipeline 21, one end of malleation pipeline 22 is connected with malleation gas circuit 31, the other end is connected with malleation hole 14, and one end of negative-pressure pipeline 21 is connected with negative pressure gas circuit 32, and the other end is connected with negative pressure hole 15.
With reference to accompanying drawing, the breast pump of present embodiment, in actual use, can collect, store with feeding bottle 4 milk of sucking-off.
