The special miniature negative-pressure adjustable drainage device for the handand foot microsurgery comprises a box body, wherein the inner wall of the bottom of one side of the box body is connected with a drainage tube; one end of the drainage tube extends to the outer sideof the box body and is connected with a drainage head; the drainage tube is connected with a washing tube; a clip is arranged on the outer side of the washing tube; a mounting hole is formed in the top of the box body; the same partition is fixedly mounted on the inner walls of the mounting hole and the box body; a rotating hole is formed in one side of the partition; a rubber plate is rotatably mounted in the rotating hole; a plurality of semispherical grooves are formed in the outer side of the rubber plate; a connecting hole is formed in the inner wall of the top side of the rotating hole;a rotating shaft is rotatably mounted in the connecting hole; the bottom end of the rotating shaft is fixedly connected with the top of the rubber plate; and the top end of the rotating shaft extendsto a position above the partition and is welded to a rotating plate. The special miniature negative-pressure adjustable drainage device for the hand and foot microsurgery is reasonable in design and convenient to operate, liquid suction and drainage functions are convenient to fulfill, during liquid suction, suction force is greatly increased and is convenient to adjust, and people use the deviceconveniently.

Description

technical field [0001] The invention relates to the technical field of drainage equipment, in particular to a miniature negative pressure adjustable drainage device for hand and foot microsurgery. Background technique [0002] Negative pressure wound treatment technology is a new technology developed in recent years for the treatment of wounds. It uses bio-semipermeable membranes to seal open wounds, uses a special negative pressure machine to generate a certain negative pressure, and acts on the wound through drainage tubes and dressings. Wound surface after debridement. In the prior art, there is a miniature negative pressure adjustable drainage device for hand and foot microsurgery, which includes a liquid storage tube and an injection plug, and the injection plug is set inside the liquid storage tube. The liquid storage tube adopts a cylindrical structure with one end open. One end of the opening of the liquid pipe is movably connected with a moving push rod, the other ...
