Abstract

The utility model relates to a duckbill one-way valve of a breast pump. The duckbill one-way valve of the breast pump comprises a horn-shaped breast support (5), a column-shaped buffer tape (8) and a one-way valve mounting head (3), wherein the one-way valve mounting head (3) is composed of two coaxial cylinders, the smaller cylinder protrudes out of the top surface of the larger cylinder, the one-way valve (4) is sleeved on the one-way valve mounting head (3), the one-way valve (4) is composed of two coaxial cylinders, the smaller cylinder protrudes out of the top surface of the larger cylinder, the side surface of the protruding smaller cylinder of the one-way valve (4) is provided with two symmetrical crossed inclined cut plane, elastic films (7) cover the two inclined planes, and a linear opening is arranged in the top portion of the crossed section of the elastic films (7). An inner cavity of the one-way valve (4) is in a hollow structure, the larger end of the inner cavity corresponds to the two coaxial cylinders of the one-way valve mounting head (3) in shape, and the one-way valve mounting head (3) is coaxially mounted in an inner cavity of a connecting pipe (2). The duckbill one-way valve of the breast pump can be used to pump breast and rectify nipples, and backflow is effectively avoided.

Description

A kind of humalactor check valve of duckbill

Technical field

This utility model belongs to maternal and child health articles for use field, particularly relates to a kind of humalactor check valve of duckbill.

Background technology

The humalactor check valve of duckbill is the key component that is applied to negative pressure adjustable type balance humalactor, and this equipment belongs to medical humalactor tool, mainly solves the problems such as women breast-feeding their children's emulsion stasis of blood is long-pending, crater nipple.It integrates inhales breast, mammary papilla correcting depression, and pressure is adjustable, and is easy to use comfortable, and breast is had protective effect, and cost is low.Being mainly used in women breast-feeding their children inhales breast or corrects crater nipple.But the not potent fruit of the most suction of commercially available humalactor is bad, and does not have effective anti-return means, and the milk that causes collecting refluxes out easily.

The utility model content

Technical problem to be solved in the utility model provides a kind of humalactor check valve of duckbill, can improve the effectiveness of inhaling breast, mammary papilla correcting, anti-backflow.

The technical scheme that its technical problem that solves this utility model adopts is: the humalactor check valve that a kind of duckbill is provided, comprise horn-like breast holder, column buffer strip and check valve mounting head, described check valve mounting head are that two coaxial clyinders and little cylinder protrude large cylinder end face; Cover has check valve on the check valve mounting head, check valve is two coaxial clyinders, little cylinder protrudes large cylinder end face, there are two oblique tangent planes of symmetrical chiasma the small cylinder side that check valve protrudes, be coated with elastica on described two inclined-planes and at the top of intersecting a linear opening arranged, and the inner chamber of check valve is hollow structure, and the shape at the large end of inner chamber place is corresponding with two concentric cylinder body profile of check valve mounting head, and the check valve mounting head is coaxially installed in the connection tube inner chamber.

Described horn-like breast holder rear portion is the column buffer strip, connection tube vertical connection column buffer strip root, and connection tube has flatly with column buffer strip junction, and vacuum generator is by therewith mouthful connection of suction pipe.

Beneficial effect

This utility model can improve the effectiveness of inhaling breast, mammary papilla correcting, and effectively anti-backflow.
