The vacuum valve 33 is a valve whose working pressure is lower than the standard atmospheric pressure, and in the vacuum system, the vacuum valve 33 is used to change the direction of the air flow, adjust the size of the air flow, and cut off or connect the vacuum system pipe. Optionally, the vacuum valve 33 in this embodiment is used to cut off or switch on the vacuum line between the suction cylinder 32 and the liquid storage tube 2. In other embodiments, the vacuum valve 33 is also used to change the direction of the air flow, adjust the magnitude of the air flow, and the like.

In this embodiment, the one end of honeycomb duct 1 is connected with the built-in flap drainage tube of human wound, and the other end is connected with liquid storage tube 2, and connecting pipe 31 sets up between liquid storage tube 2 and pump bowl 32, and is provided with vacuum valve 33 in the connecting pipe 31. When the air extracting cylinder 32 extracts air, the vacuum valve 33 is opened to connect the vacuum pipeline between the air extracting cylinder 32 and the liquid storage pipe 2, so that the interior of the liquid storage pipe 2 is in a negative pressure state, and the air and the effusion at the wound surface are led out to the liquid storage pipe 2 through the guide pipe 1. When the air pumping cylinder 32 stops pumping air, the vacuum valve 33 is closed, and the vacuum pipeline between the air pumping cylinder 32 and the liquid storage pipe 2 is cut off, so that the negative pressure state is continuously kept in the liquid storage pipe 2, and the pneumatosis hydrops under the wound surface flap can be automatically drained.

When the connecting pipe 31 is in threaded connection with the liquid storage pipe 2, the phenomenon that the pipeline loosens to generate invalid negative pressure can be avoided, and the probability of cross infection is reduced. In addition, because the drainage liquid has high viscosity and small pressure difference, the threaded connection part of the connecting pipe 31 and the liquid storage pipe 2 can form threaded seal, thereby preventing the drainage liquid from leaking outwards.

In some embodiments, as shown in fig. 2, the connection tube 31 includes a fixed portion 311 and a movable portion 312, the movable portion 312 is located at an end of the fixed portion 311 away from the liquid storage tube 2, the vacuum valve 33 is disposed at the fixed portion 311, and the pumping opening of the pumping cylinder 32 is disposed at the movable portion 312.

In order not to affect the post-operation activities and functional exercises of the patient, the movable portion 312 of the connection tube 31 may be separated from the fixed portion 311 while the suction cylinder 32 is discarded, thereby giving the patient a larger activity space.

In one example, as shown in fig. 2, a crease 313 is formed at a position where the fixed part 311 of the connection pipe 31 and the movable part 312 are butted. Since the connection tube 31 has a weak strength at the fold 313, the movable portion 312 is easily broken and separated from the fixed portion 311 together with the suction tube 32.

In some embodiments, the inner diameter of the connection pipe 31 is larger than the inner diameter of the draft tube 1 and smaller than the inner diameter of the reservoir 2. The honeycomb duct 1 with smaller inner diameter can generate relatively larger pressure, so that accumulated gas and accumulated liquid can be conveniently led out to the liquid storage tube 2 from the flap drainage tube. The liquid storage pipe 2 with the larger inner diameter can release the pressure of the drainage liquid to prevent the drainage liquid from entering the connecting pipe 31. Because the vacuum valve 33 is arranged in the connecting pipe 31 and is not contacted with the drainage liquid in the liquid storage pipe 2, the sterile environment in the liquid storage pipe 2 can be ensured, and the probability of cross infection is further reduced.
