Abstract

The utility model discloses a novel breast pump, aiming to overcame the shortcoming of the prior breast pump that the sucker is very difficult to poll out after the milk has been drunk out. The novel breast pump comprises sucker, milk bottle, pipe and pump ball that is made of elastic material, both ends of pump ball are provided with the first valve, the second valve; the first and the second valve consist of incision, the two valves are closed in no working status; the relief valve is provided on the pipe. When in use, the relief valve closed, after finished sucking the milk, the utility model can bend the guide pipe backward the relief valve, then the incision of relief valve opened and outer air flows into sucker through guide pipe to make the inside breast pump being normal pressure, which makes the pulling of sucker from parturient easily with being convenient and practical.

Description

Novel breast pump

Affiliated technical field

This utility model relates to a kind of breast pump.

Background technology

The breast pump that uses is to constitute so at present, comprise that sucker, feeding bottle, conduit reach the pump of being made by elastomeric material and pounce on ball, pump is pounced on the ball two ends and is provided with valve, two valves all are otch, two valves are normally off when not working, it is to be combined by two hemispheres that pump is pounced on ball, again two valves and pump pounce on ball neither be integrally formed, manufacturing cost is higher like this; During use, sucker is placed on the breast, push, loosen pump back and forth with hands then and pounce on ball, constantly take the air in the sucker away, make that vacuum improves constantly in the sucker, thereby make the milk sucking-off and flow in the feeding bottle; When sucking milk, the vacuum in the sucker is very high, owing to the existence of external atmosphere pressure, will extract sucker from breast like this and become very difficult, it is very painful that the puerpera can feel.

Summary of the invention

In order to overcome existing breast pump after sucking milk, the very difficult deficiency of extracting of sucker from breast; This utility model provides a kind of novel breast pump for this reason, and this novel breast pump is easy to extract from puerpera's breast after sucking milk, can not bring misery to the puerpera.

This utility model for the technical scheme that solves its technical problem and adopt is: this novel breast pump, comprise that sucker, feeding bottle, conduit reach the pump of being made by elastomeric material and pounce on ball, pump is pounced on the ball two ends and is respectively equipped with first valve, second valve, first and second two valves all are made up of otch, two valves are not normally off when not working, and conduit is provided with pressure relieving valve.

It is integrally formed with first and second valve that pump is pounced on ball.

Conduit is made by elastomeric material.

Pressure relieving valve is supravasal otch.

The beneficial effects of the utility model are: because pressure relieving valve is set on conduit, this pressure relieving valve is a supravasal otch, make cut closure when sucking, after sucking milk, otch twist and warping conduit opens otch dorsad, at this moment can flow into air in the conduit, thereby not have vacuum in the sucker, sucker also just is easy to pull up from breast, and the puerpera can not feel any pain; Pump is pounced on ball and pump to pounce on first and second valve at ball two ends integrally formed again, can lower fault like this, improve using character, and make manufacturing cost lower, and product competitiveness is stronger.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

The specific embodiment

Embodiment: referring to Fig. 1, a kind of novel breast pump, the conduit 2 that comprises sucker 1, feeding bottle 3, makes by elastomeric material and pounce on ball 4 by the pump that elastomeric material is made, pump is pounced on ball 4 two ends and is respectively equipped with first valve 5, second valve 6, first and second two valves 5,6 all are made up of otch, first and second valve 5,6 is not normally off when not working, and conduit 2 is provided with pressure relieving valve 7; Pressure relieving valve 7 is the otch on the conduit 2; It is integrally formed with first and second valve 5,6 that pump is pounced on ball 4.

Use of the present utility model is: sucker 1 is close to breast, make cut closure as pressure relieving valve 7, push repeatedly with hands, loosen pump and pounce on ball 4, when extrusion pump is pounced on ball 4,6 distortion of second valve are opened, first valve 5 is not by the external force effect and closes shape, the air that pump is pounced in the ball 4 is discharged, when loosening pump and pounce on ball 4, second valve 6 recovers original shut state, because pouncing on ball 4, pump is elastomer, pump is pounced on ball 4 will recover initial condition, in this process, its inner space increases gradually, makes pump pounce on intrinsic pressure diminishing in the ball 4, there is the certain vacuum degree, first valve, 5 outer conduit 2 internal gas pressures are normal pressure again, also there is the certain vacuum degree by intrinsic pressure the washing open in the conduit 2 in such first valve 5 thereby make in the conduit 2, until pouncing on vacuum balance in the ball 4 with pump, first valve 5 is just closed again; Push, loosen pump again and pounce on ball 4, renew so again, can extract air in conduit 2, sucker 1 and the feeding bottle 3 out, make and produce vacuum in the sucker 1, until the milk sucking-off; After sucking milk, sucker 1 vacuum is very high, will be from the breast sucker 1 be extracted and becomes very difficult, at this moment dorsad outgas valve 7 bending conduits 2, make disruption of wound as outgas valve 7, thereby outside air flows in the suckers 1 by conduit 2, make breast pump inside revert to normal pressure, so just be easy to pull up sucker 1 from puerpera's breast, convenient and practical, and pump is pounced on ball 4 and first and second valve 5,6 is integrally formed, can lower fault, improve using character, reduce manufacturing cost simultaneously.

In this utility model, the outgas valve 7 on the conduit 2 is an aperture also, with the finger closed pores, sucks the back and opens aperture when sucking; Certainly outgas valve 7 also has other different structures; All belong to the claimed scope of this utility model.
