Suction imitation positive and negative pressure breast pump

Abstract

The invention relates to a suction imitation positive and negative pressure breast pump, which can effectively improve milk discharge effect and solve the problem of milk accumulation. In the breast pump, the side face of a shell of a negative pressure cabin is provided with a milk suction disk port; the port is provided with a milk suction disk; an air bag is arranged in the milk suction disk and communicated with an exhaust hole; the lower part of the shell of the negative pressure cabin is provided with a milk bottle; a positive pressure cabin elastic piston is arranged in the negative pressure cabin; an upper opening part of the negative pressure cabin and an upper opening part of a positive pressure cabin are provided with cabin covers; a lifting rod which is extended out of the upper part of the cabin cover is arranged at the inner bottom of the positive pressure cabin; the negative pressure cabin, the positive pressure cabin, the lifting rod and the cabin covers form a positiveand negative pressure cabin integrated linkage device; the lower part of the lifting rod is provided with a positive pressure cabin delay exhaust switch in the positive pressure cabin; the cabin cover on the upper part of the positive pressure cabin is provided with a delay exhaust device which is communicated with the positive pressure cabin; the outer wall of the shell of the negative pressure cabin is provided with a compression bar supporting column; a compression bar which is connected with the lifting rod is arranged on a compression bar supporting port of the upper part of the compression bar supporting column; and the upper part of the cabin cover is provided with a canopy which covers the delay exhaust device. The breast pump has a novel and unique structure, is convenient to useand truly achieves the milk discharge effect of completely imitating milk suction of infants.

Description

1. Technical field [0001] The invention relates to a breast pump, in particular to a positive and negative pressure breast pump imitating sucking. 2. Background technology [0002] At present, most of the breast pumps sold on the market are single negative pressure breast pumps, which use the principle of leverage to depress the handle and raise the lift rod of the positive pressure bin. The lift rod of the positive pressure bin drives the elastic piston to contract. Negative pressure is generated inside, and the negative pressure attracts the breast and areola through the sucking plate, and the suction of the negative pressure alone promotes the discharge of milk. areola movements. Therefore, the milk discharge effect of the single negative pressure breast pump is not ideal, and it is imperative to improve and innovate the breast pump. 3. Content of the Invention [0003] In view of the above situation, in order to solve the defects of the prior art, the purpose of the ...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the breast pumps sold on the market are single negative pressure breast pumps, which use the principle of leverage to depress the handle and raise the lever of the positive pressure chamber. Negative pressure is generated inside, and the negative pressure attracts the breast and areola through the sucking pan, and the suction of the negative pressure alone promotes the discharge of milk. It cannot be like an infant sucking milk, which has both negative pressure sucking action and lip gathering and squeezing Movement of the areola

Therefore, the milk discharge effect of the single negative pressure breast pump is not ideal, and the improvement and innovation of the breast pump is imperative
