Abstract
The utility model is a medical and heath care supplies, which relates to an improved two-tube breast pump, comprising a sucking bra, an observation tube and a piston. The piston is arranged in the observation tube. The front end of the observation tube is provided with two fluid outlets that are respectively communicated with the sucking bra and a stock solution container by a transfusion tube. The transfusion tube is provided with a switch. The utility model, which is easy to be used and can increase sucking pressure that can be adjusted, has reasonable structure, wide adjustment range, good effect and wide application.
Description
Technical field
This utility model relates to a kind of improved breast pump, is medical, health product.
Background technology
Breast pump originally is made up of compression balloon and breast cup, and suction is little, can not carry out blower operations, has influenced the effect that sucks.The patent No. is that 99224122.7 piston type breast pump has had the effect that sucks that further improved.This breast pump comprises breast cup, takes out tube, piston, and piston places takes out tube, and the pull piston forms negative pressure-pumping milk, taking out a front end is breast cup, take out barrel and be provided with liquid storage cylinder, have liquid outlet on the liquid storage cylinder, the milk of sucking-off flows directly into liquid storage container from liquid outlet.This breast pump can be implemented pressurized operation by the pull piston, but the milk of drawing needs special control to broadcast the liquid storage container from liquid storage cylinder, operation inconvenience, and can only carry out disposable pull negative-pressure operation, the pressure adjusting range is limited, and it is not fine adjusting effect.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of rational in infrastructure, the suction pressure adjusting range is big, and is effective, uses easy to operate double hose breast pump,
Double hose breast pump described in the utility model, comprise breast cup, take out tube, piston, piston places takes out tube, and its front end of taking out tube is provided with two liquid outlets, two liquid outlets are communicated with breast cup, liquid storage container by infusion tube respectively, and infusion tube is provided with switch.
During use,, promote piston earlier with the switch opens on the infusion tube, gas is wherein discharged, close again with flexible pipe that liquid storage container is connected on switch, with breast cup by being placed on the breast pull piston, the milk suction is taken out in the tube, close again with flexible pipe that breast cup is connected on switch, open with flexible pipe that liquid storage container is connected on switch, promote piston, the milk of drawing is drained in the liquid storage container, finish a cycling.So repeatedly, can carry out repeatedly cycling, realize different pressure operations.Cycle-index is many, and pressure is big.Adjustable in pressure, adjustable range is big, draws effectively, and uses easy to operate, pollution-free.
Be with sealing ring on the piston, guarantee the negative-pressure sucking effect.
Switch is the plastics roll extrusion switch on the disposable medical transfusion device, and is simple in structure, uses easy to operate.
This utility model is rational in infrastructure, uses easy to operately, can increase suction pressure, and suction pressure is adjustable, and adjusting range is big, and is effective, is beneficial to and applies.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Among the figure: 1, breast cup 2,9, transfusion sebific duct 3,10, plastics roll extrusion switch 4, liquid outlet 5, take out a protecgulum 6, take out tube 7, rubber seal 8, piston 11, connect the tail button.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
As shown in the figure, double hose breast pump described in the utility model, comprise breast cup 1, take out tube 6, piston 8, piston 8 places takes out tube 6, be with rubber seal 7 on the piston 8, the front end of taking out tube 6 is provided with 4, two liquid outlets 4 of two liquid outlets and is communicated with breast cup 1, liquid storage container by transfusion sebific duct 2,9 respectively, and infusion tube 2,9 is provided with plastics roll extrusion switch 3,10.
During use, earlier the switch on the infusion tube 2,93,10 is opened, promoted piston 8, gas is wherein discharged, close switch 10 again, with breast cup 1 by being placed on the breast pull piston 8, the milk suction is taken out in the tube 6, close switch 3 again, open switch 10, promote piston 8, the milk of drawing is drained into by in the liquid storage container that connects 11 connections of tail button, finish one and draw cycling.
