Abstract
The utility model provides a vacuum continuous milk pump, relates to the amelioration of a milk pump, is composed of a fared nipple shield (1), a connecting tube (2), an one-way outlet valve (3), a sealing gland (4) and an elastic feeding bottle (5), and is characterized in that the upper of the elastic feeding bottle (5) is screwedly connected with the sealing gland (4), which is respectively provided with the connecting tube (2) and the one-way outlet valve (3). The lower end of the connecting tube (2) is communicated with the inner cavity of the elastic feeding bottle (5), while the upper end of the connecting tube (2) is communicated with the fared nipple shield (1). The utility model has the advantages of simple structure, and convenient and sanitary usage. The milk is directly absorbed into the elastic feeding bottle, and the continuous sucking can be fulfilled by constantly extruding the elastic feeding bottle.
Description
Technical field
This utility model relates to a kind of improvement of breast pump, a kind of specifically negative pressure continous way breast pump.
Background technology
Present breast pump mostly is the structure that connects the negative pressure leather bag behind the horn mouth, although the breast pump that has is provided with the storage feeding bottle between negative pressure leather bag and horn mouth, but still be the air of discharging earlier in the negative pressure leather bag, horn mouth is coincide sucks with negative pressure on breast then, whenever suck once, all breast pump to be taken off from breast, pinch flat leather bag, discharge the air in the leather bag with hands, coincide once more and on breast, suck, desultory sucking, promptly inconvenient, also unhygienic.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can continuously extruded feeding bottle, realize the negative pressure continous way breast pump that sucks continuously.
The purpose of this utility model is achieved in that this negative pressure continous way breast pump is made up of horn-like nipple shield, connection tube, unidirectional air outlet valve, seal cover, elasticity feeding bottle, the top of the elasticity feeding bottle seal cover that is being threaded, be respectively equipped with connection tube and unidirectional air outlet valve on the seal cover, the connection tube lower end communicates with elasticity feeding bottle inner chamber, and the upper end is connected with horn-like nipple shield.
When specifically using this utility model, horn-like nipple shield is coincide on breast, extruding elasticity feeding bottle, air in the elasticity feeding bottle is discharged by unidirectional air outlet valve, utilize the interior negative pressure of elasticity feeding bottle with the milk sucking-off, because the air in the feeding bottle can only go out and can not advance, so continuously extruded elasticity feeding bottle can be realized uninterruptedly sucking.
Advantage of the present utility model: simple in structure, easy to use, health, milk directly are inhaled into the elasticity feeding bottle, and continuously extruded elasticity feeding bottle can be realized uninterruptedly sucking.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this negative pressure continous way breast pump is made up of horn-like nipple shield 1, connection tube 2, unidirectional air outlet valve 3, seal cover 4, elasticity feeding bottle 5, the top of elasticity feeding bottle 5 seal cover 4 that is being threaded, be respectively equipped with connection tube 2 and unidirectional air outlet valve 3 on the seal cover 4, connection tube 2 lower ends communicate with elasticity feeding bottle 5 inner chambers, and the upper end is connected with horn-like nipple shield 1.
Claims (1)
1, a kind of negative pressure continous way breast pump, form by horn-like nipple shield (1), connection tube (2), unidirectional air outlet valve (3), seal cover (4), elasticity feeding bottle (5), the top that it is characterized in that elasticity feeding bottle (5) seal cover (4) that is being threaded, be respectively equipped with connection tube (2) and unidirectional air outlet valve (3) on the seal cover (4), connection tube (2) lower end communicates with elasticity feeding bottle (5) inner chamber, and the upper end is connected with horn-like nipple shield (1).
