The working principle and the using process of the invention are as follows: firstly, medical care personnel place medical sponge to a wound, then align the fixing ring 201 at the middle position of the biological semipermeable membrane 1 with the movable sponge, so as to stick the biological semipermeable membrane 1 to the outside of the skin of a patient, then pull the bonding buckles 218 at two sides, stretch the elastic cloth belt 217 to make the elastic cloth belt 217 stick to the outside of the body of the patient, then bond the two bonding buckles 218, so as to drive the fixing rubber belt 215 to more tightly bond the biological semipermeable membrane 1 to the outside of the biological semipermeable membrane 1, and prevent the biological semipermeable membrane 1 from falling off when the patient moves;

when the medicine needs to be changed, medical staff unscrews the rotating block 203 to drive the threaded disc 202 to rotate, then the limit of the threaded disc 202 on the sealing pressing plate 205 is removed, the medical staff can quickly change the medical sponge immediately, after the change is finished, the medical staff screws the threaded disc 202 to the inner side of the fixing ring 201 from the new state, so that the sealing is carried out again, then the medical staff uses the needle tube to be communicated with the luer connector 214, then the medicine to be used can be injected to the inner side of the shunting box 208 through the branch tube 212, and then the medicine is injected into the medical sponge through the circulation groove 210 on the outer side of the collecting and releasing tube 209, so that the medicine is applied to the affected part, the contact between the affected part and the outside air is reduced, the affected part is prevented from being contacted with germs in the air, and the infection of the affected part is prevented;

the medical sponge can be quickly replaced by unscrewing the threaded disc 202, and the biological semipermeable membrane 1 does not need to be removed again and is pasted newly, so that the discomfort of the old patient is reduced, the application range of the negative pressure technology is improved, the negative pressure rehabilitation effect is improved, and the quick recovery of the patient is facilitated;

then, after the adhesion of the bio-semipermeable membrane 1 is finished, the transverse telescopic rods 401 are pulled to extend to the bottom position of the main negative pressure tube 211, then the longitudinal telescopic rods 402 are pulled to enable the fixing forks 403 at the top ends of the longitudinal telescopic rods 402 to be clamped at the outer side of the main negative pressure tube 211 to support the main negative pressure tube 211, the movable blocks 406 can be rotated at the inner side of the rotating seats 404 to stretch the inclined telescopic rods 407 to support the main negative pressure tubes 211 at different angles, after all the main negative pressure tubes 211 are supported to proper positions, the main negative pressure tube 211 can be prevented from being pressed by the weight of the main negative pressure tube 211 due to internal liquid during negative pressure drainage, the bio-semipermeable membrane 1 is protected from falling off by the main negative pressure tube 211, the negative pressure drainage can be normally performed, and the negative pressure drainage effect is further improved;

finally, when the medical staff normally uses the negative pressure device in the hospital, the external negative pressure machine is communicated with the bottom one-way valve 307 through a pipeline, at the moment, when negative pressure is performed for a period of time, the pressure in the main tank body 301 is reduced, so that the main tank body 301 conducts drainage through the main negative pressure pipe 211, at the moment, the extravasation liquid at the wound is absorbed and drained into the main tank body 301 through the main negative pressure pipe 211, and meanwhile, because the pressure in the main tank body 301 is reduced, the alcohol in the alcohol barrel 323 can press down the flow stopping sheet arranged at the bottom of the central sliding rod 321, so that the alcohol can flow into the sliding tank body 304, so that the body fluid after drainage is sterilized, the germs are prevented from being continuously grown, the medical staff are prevented from infecting the germs when the sliding tank body 304 is replaced and cleaned, and after one-time negative pressure is over, the flow stopping sheet can be tightened again by the tightening spring 322, preventing the alcohol from continuing to flow;

but when medical personnel rescued in the disaster area, thereby can make slip outer loop 309 overcome reset spring 315's elasticity effect through pulling rotation screw ring 311, so that slip jar body 304 slides downwards in main jar of body 301's inside, thereby make main jar of body 301's inside produce the negative pressure, thereby carry out the drainage with patient's body fluid through main negative pressure pipe 211, thereby guarantee that the injured people in disaster area can carry out the negative pressure drainage and recover, here simultaneously the inside alcohol of alcohol bucket 323 also can flow down and kill the germ, and after a period of use, can unscrew rotation screw ring 311 thereby relieve the restriction of block thread bottom plate 310 to slip jar body 304, then take off slip jar of body 304 and wash, guarantee to reuse.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
