Tubular negative pressure drainage apparatus for orthopedics department

Abstract

The invention discloses a tubular negative pressure drainage apparatus for orthopedics department, which comprises an inner tube located inside a wound and an outer tube located outside the wound, the outer tube is located at the top of the inner tube and communicated with the inner tube, a plurality of evenly-distributed side holes are formed in the side wall of the inner tube, and the inner tube is filled with sponge. An existing aspirator is improved, the sponge is plugged into the inner tube structure, the side holes are formed in the inner tube, the problems that the sponge falls off and is difficult to replace do not exist, and the tubular negative pressure drainage device has the advantages that the tubular negative pressure drainage device can be safely used for a sinus tract or a wound surface with a deep wound, and the risk that the sponge falls off and the like does not occur; and the negative pressure attraction in the wound is more uniform. The tubular negative pressure drainage apparatus is simple in structure, when the sponge needs to be taken out, the sponge can be conveniently and completely taken out, dead space is avoided, and wound healing is accelerated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a tubular negative pressure drainage device used in orthopedics. Background technique [0002] Negative pressure drainage device is used for clinical orthopedic drainage. It guides the pus, blood, liquid and other body fluids exuded or accumulated on the surface of human tissue wounds with surface defects or degloving to the outside of the body, preventing wound fluid accumulation, infection, and promoting wound healing. A medical device. There are many types of orthopedic negative pressure drainage devices used clinically, and they are generally made of materials such as sponges, sterile sealing films, and silicone rubber drainage tubes. When in use, the sponge part is placed on the drainage site of the skin defect or the degloving wound, covered with a sealing protective film, and the sealing film is pierced and connected to the drainage tube and further co...
