Built-in negative pressure type breast pump

Abstract

The invention discloses a built-in negative pressure type breast pump, and the breast pump comprises a suction device assembly and a negative pressure source; the suction device assembly comprises a milk storage bottle, a milk suction cover and a connecting part, wherein the connecting part is provided with a first end, a second end and a third end which are communicated with the milk storage bottle, the milk suction cover and the negative pressure source respectively; the breast pump further comprises a negative pressure regulator and a one-way milk channel. On the one hand, the negative pressure regulator is internally arranged, the formed negative pressure regulation space is enlarged, the amount of milk sucked at a time is large, repeated milk sucking is not needed, and breast distending pain of a puerpera is rapidly relieved; on the other hand, negative pressure is kept in the feeding bottle, the state that an infant sucks breast milk is simulated, the effects of massage and lactation promotion are achieved, a puerpera feels comfortable and does not feel painful when using the feeding bottle, meanwhile, the milk sucking cavity is closed in the whole process, the problem that milk flows out when the puerpera sucks milk in a reclining mode or a side lying mode is effectively solved, and the feeding bottle is particularly suitable for cesarean mothers.

Description

technical field [0001] The invention belongs to the field of breast pumps, in particular to a built-in negative pressure breast pump. Background technique [0002] As we all know, when a puerpera gives birth to a baby, she cannot secrete milk in time, and cannot make the baby breastfeed naturally and smoothly, so she needs to use a sucking tool to make it produce milk in time; and some puerpera have excess sucking capacity relative to the baby after giving birth, making the puerpera's breast Painful breastfeeding, and breastfeeding tools are needed to suck out the excess milk. [0003] At present, breast pumps on the market include electric breast pumps and manual breast pumps, the fundamental principle of which is to suck out milk by means of negative pressure adsorption. [0004] However, in actual use, existing breast pumps tend to have the following problems: [0005] 1) The amount of breast milk that can be absorbed at one time is small. Once the mother has too much m...

AI Technical Summary

Problems solved by technology

[0005] 1) The amount of breast milk that can be absorbed at one time is small. Once the mother has too much milk, it needs repeated breastfeeding to relieve the pain of the mother's breast. Therefore, it is time-consuming and laborious, and the pain cannot be relieved quickly, and the experience is poor. ;

[0006] 2) Generally, during the process of breastfeeding, the milk drips into the bottle by its own weight, and there will be no pressure inside the bottle. In this way, it is easy to cause milk leakage when reclined or lying on the side while sucking. outflow;

[0007] 3) During the entire breastfeeding process, since there is no negative pressure inside the bottle, it is impossible to simulate the sucking state of the baby with the mother's nipple in its mouth. Massage and the effect of promoting milk secretion
