Description

Simple breast shield

Technical Field

The utility model relates to the technical field of mother and infant products, in particular to a simple breast shield.

Background

The existing three-way parts for sucking milk comprise a rigid sucking shield, a flexible liner, a one-way valve and the like, and the liner is arranged in the sucking shield and is combined with the one-way valve.

The existing breast pump tee on the market has the following problems: the breast tee fitting includes a rigid breast shield, a flexible liner, and the like. The combination of rigid breast shields and flexible liners is stiff and does not conform well to the breast.

For example, chinese patent CN 112190777A discloses the following technical contents: a breast shield for a breast pump for pumping human breast milk has a rigid base part with a tubular adapter and a funnel molded in one piece on the adapter and widening away from the adapter for receiving a mother's breast. The breast shield further comprises a flexible flange which is arranged on the funnel at its end facing away from the adapter tube and which is designed for abutment against the mother's breast. The end of the funnel forms a first abutment surface. The flange has an end facing the funnel, which end forms a second abutment surface, wherein the first and second abutment surfaces abut each other in the circumferential connection seam. The funnel has a first wall thickness in the region of the connecting seam and the flange has a second wall thickness which is approximately as large as the first wall thickness. Preferably, the first wall thickness and the second wall thickness are exactly the same, that is to say the first wall thickness and the second wall thickness are exactly the same.

Although the above technical solution also has a rigid base member and a flexible flange, the structure is a single layer lamination, and sometimes the phenomenon of milk leakage occurs.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model provides a simple breast shield with a double-layer flexible inner wall structure and high fitting degree. In order to solve the technical problems, the utility model provides the following technical scheme:

a simple breast shield comprises a base and an edge, wherein the breast shield is further provided with a first shield, the base and the edge are connected to form a second shield, and a containing cavity is formed between the first shield and the second shield in a hollow mode.

The accommodating cavity is used for enhancing the fit degree of the protective cover and the skin and can also accommodate exuded emulsion.

On the basis of adopting the technical scheme, the utility model can also adopt the following further technical scheme:

the end of the base is provided with a first one-way valve which is communicated unidirectionally from inside to outside of the base.

The side part of the base is also provided with an air suction port.

The first shield is hollow to form a breast pumping chamber, and the breast pumping chamber is enclosed in the second shield. The breast pump chamber is used for containing nipple and milk.

The wall of the breast pumping cavity is provided with a second one-way valve which is communicated in one way from the outside of the breast pumping cavity to the inside of the breast pumping cavity.

In the working state of the breast shield, the breast pump cavity and the accommodating cavity are both negative pressure cavities. Namely, when the breast pump sucks milk, the first one-way valve is sealed and closed, the breast is tightly attached to the breast sucking cavity, the breast sucking cavity forms a negative pressure cavity, meanwhile, the breast is tightly attached to the flexible edge, the second one-way valve is opened, air in the accommodating cavity is partially pumped away, and another negative pressure cavity is formed, so that the shield is firmly attached to the breast.

The base is made of a rigid material and the rim and the first shield are made of a flexible material.

The first shield and the second shield are integrally formed.

Compared with the prior art, the utility model has the following beneficial effects:

the two shields of the utility model can play a good role in supporting and fitting the breast, the shield is firmly fitted on the breast, and the risk of milk leakage is greatly reduced during milk sucking. Meanwhile, the structure of the double-layer flexible inner wall is designed, so that the fitting degree of the bra and a human body is increased, and the use experience of the product can be better improved.

Detailed Description

A simple breast shield provided by the present utility model will be further described with reference to the accompanying drawings.

1-3, a simple breast shield includes a base 1, an edge 2 and a first shield 3.

Wherein, base 1 links to each other with edge 2 and constitutes the second shield, and cavity constitutes holding chamber 4 between first shield 3 and the second shield. The accommodating cavity 4 is used for enhancing the fit degree of the protective cover and the skin, and can also accommodate exuded emulsion.

Further, the base 1 is made of a rigid material and the rim 2 and the first shield 3 are made of a flexible material.

Further, the first shield 3 and the second shield are integrally formed, i.e. the base 1, the edge 2 and the first shield 3 are integrally formed.

Further, the end of the base 1 is provided with a first one-way valve 11, and the first one-way valve 11 is in one-way conduction from the inside of the base 1 to the outside of the base 1.

Further, the side of the base 1 is also provided with an air suction port 12.

The first shield 3 is hollow to form a breast pumping chamber 31, the breast pumping chamber 31 is enclosed in the second shield, and the breast pumping chamber 31 is used for accommodating nipple and milk.

Further, a second one-way valve 32 is arranged on the wall of the breast pump cavity 31, and the second one-way valve 32 is communicated unidirectionally from the outside of the breast pump cavity 31 to the inside of the breast pump cavity 31.

The working state is as follows: in the operational state of the breast shield, both the breast chamber 31 and the receiving chamber 4 are negative pressure chambers.

Specifically, when the breast pump is used for sucking milk, the first one-way valve 11 is sealed and closed, the breast is tightly attached to the breast sucking cavity 31, the breast sucking cavity 31 forms a negative pressure cavity, meanwhile, the breast is tightly attached to the flexible edge 2, the second one-way valve 32 is opened, air in the accommodating cavity 4 is partially pumped away, and another negative pressure cavity is formed, so that the shield is firmly attached to the breast.

In the second embodiment, the base 1 is made of plastic, and the edge 2 and the first shield 3 are made of soft rubber. The other is the same as in the first embodiment.

While the utility model has been shown and described with reference to a preferred embodiment, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the utility model.
