Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-2, the present utility model provides a first embodiment:

the negative pressure skin expander convenient for the patient to pump automatically comprises an outer expander 6, wherein the upper end of the outer expander 6 is provided with a one-way valve body 4 which is used for communicating with negative pressure equipment;

the outer surface of the outer expander 6 is provided with a pressure detector 6 with a digital display, the detection end of the pressure detector 6 extends into the outer expander 6, the pressure in the outer expander 6 is detected by the pressure detector 6, and the pressure value is displayed in a digital form;

the air outlet end of the elastic air bag 7 is provided with an air outlet end one-way valve 7.

So, through the observation to the pressure numerical value that pressure detector 6 shows, when the inside pressure of outer expander 6 is less than rated range, open check valve body 4 through extrusion fixture block 3, make elasticity gasbag 7 and outer expander 6 intercommunication, the inside air of outer expander 6 is taken out to extrusion elasticity gasbag 7 this moment, increase the inside negative pressure of outer expander 6, and then make the inside pressure of outer expander 6 keep in rated range, improve the efficiency of skin expansion, make the patient can take out the pressure by oneself at home, need not to get back to the hospital again, the inconvenience is reduced.
