During washing, disinfection or medicine application, because spraying operation is carried out on different positions in a wound, the spray gun 100 needs to swing or move in a certain range in the operation process, and as the liquid receiving device 200 is rotatably connected with the gun shell 101 and the liquid receiving bag 203 is connected with the connecting cylinder 201 through the elastic rod 202, the liquid receiving bag 203 can still be effectively attached to the skin below the wound when the spray gun 100 swings or moves in a reasonable range. The liquid flowing out from the wound flows into the liquid receiving bag 203 under the action of gravity, and is quickly sucked away through the recovery hose 204 and the negative pressure pipe 112, so that the problem that the liquid flowing out of the wound pollutes the surrounding environment during wound treatment is effectively solved.
