Antibacterial disinfection device for wounds

Supporting springs are welded to the bottom end of a bearing placement plate, a discharging plate is clamped to one end of a discharging electric push rod, a sliding electromagnetic plate is connected between two electric sliding rails, torsion springs are welded to the two ends of a placement fixing plate, and clamping attaching plates are welded to one ends of the torsion springs. A wound fixing band is pushed to the top end of a placement fixing plate through a discharging electric push rod and a discharging plate, then a bearing placement plate is driven by a supporting spring to ascend, so that materials can be rapidly supplied when the wound fixing band needs to be discharged, and air between the wound fixing band and the placement fixing plate is extracted through an air extracting pump, an inlet and outlet pipe, an exhaust box and an inlet and outlet groove; the placement stability of the wound fixing band is guaranteed, an electric sliding rail drives a sliding electromagnetic plate to ascend, then a
