Problems solved by technology

Breast pumps currently on the market generally include a breast shield with a flaring opening for contact with the breast, a container for collecting milk, and a negative pressure for forming a negative pressure so that the milk flows from the breast to the breast shield. Pressure mechanism, the general negative pressure mechanism uses a breast pump to form a negative pressure on the breast shield. This negative pressure mechanism makes the structure of the breast pump complex and bulky, causing inconvenience in use and carrying.
In order to simplify the structure, some people have developed such a breast pump: that is, a breast shield, an air storage device, and a negative pressure generating device are installed on the air storage device, and the negative pressure generating device is used to make the gas storage device generate negative pressure. The device is manually operated, and the structure is relatively simple, but the negative pressure of this breast pump cannot be adjusted, and the user cannot adjust the milk flow according to the actual situation, and cannot adjust to a more comfortable state according to the actual situation

Embodiment 1

[0058] see Figure 1 to Figure 6 , the breast pump with adjustable negative pressure in this embodiment includes a main body 1, a milk collector 11 is connected to the lower end of the main body 1, the main body includes an air storage tank 12, and the air storage tank 12 is provided with a protruding handle 12a. The air storage tank is connected with a breast shield 13, and the breast shield 13 has a flaring opening 13a adapted to the shape of the breast, and an air cushion 9 is also provided on the inner lower part of the flaring; It communicates through the via hole 14 .

[0059] A piston seat 7 is arranged in the gas storage tank 12, and two air bags 5,6 are placed in the piston seat 7, and a compression guide block 4 is provided above the air bags 5,6; the piston seat is provided with a connecting rod 7a, and the connecting rod 7a passes through The guide block 4 is connected with a handle 2 by compressing it.

[0060]This embodiment is also provided with a negative pr...

Embodiment 2

[0069] see Figure 7-8 , the difference from Example 1 is:

[0070] 1. Only one airbag 5 is set in this embodiment, and the structure is also different from that of the airbag in Embodiment 1, see Figure 6 , the air bag 5 of the present embodiment is a cylindrical annular body, and the air bag is sleeved on the connecting rod 7a of the piston seat 7 through the middle space, and the piston seat 7 is not provided with a groove for placing the air bag as in the first embodiment, It is a plane, the bottom of the air bag 5 contacts the upper surface of the piston seat, and the top contacts the compression guide block. Compared with the structure of embodiment one, the contact area between the air bag 5 and the piston seat and the compression guide block is larger, and the air bag is compressed and recovered more easily. Stablize.

[0071] 2. A surrounding wall 15 is provided around the conduction hole 14 in this embodiment, which can prevent the countercurrent milk or misty mil...

Abstract

The invention discloses a negative pressure adjustable breast pump. The breast pump comprises a pump cover, an air storage tank, a negative pressure generating mechanism, a negative pressure adjusting mechanism, a control mechanism and a milk storage device, wherein the flared pump cover matches with the shape of a breast; the air storage tank is communicated with the inside of the pump cover; the negative pressure generating mechanism is arranged in the air storage tank and provided with an elastic element which can shrink after being forced; the air storage tank is provided with the negative pressure adjusting mechanism which can move axially relative to the air storage tank and change the size of the inside space of the air storage tank; the control mechanism exerts on the negative pressure generating mechanism to enable the elastic element to compress and negative pressure to be generated in the air storage tank; and the milk storage device is used for collecting the milk pumped from the pump cover and is provided with a pump valve at the inlet. According to the negative pressure adjustable breast pump, the inside space of the air storage tank can be changed due to the arrangement of the negative pressure adjusting mechanism, and therefore the generation intensity of the negative pressure can be changed. A user can adjust the negative pressure intensity as required and enables the body to be in a comfortable state.

Description

technical field [0001] The invention relates to the technical field of breast pumps, in particular to a breast pump with adjustable negative pressure. Background technique [0002] In the breastfeeding process of infants and young children, breastfeeding is involved, and a breast pump is required. This type of breast pump acts on the breast, and squeezes the breast through negative pressure to suck out the milk to achieve a good milk production effect. Breast pumps currently on the market generally include a breast shield with a flaring opening for contact with the breast, a container for collecting milk, and a negative pressure for forming a negative pressure so that the milk flows from the breast to the breast shield. Pressure mechanism, general negative pressure mechanism adopts breast pump to make breast shield form negative pressure, and this negative pressure mechanism makes breast pump structure complex, huge, causes the inconvenience of using and carrying. In order ...
