Abstract

The invention discloses a simplified combination for knee joint cavity lavage. The simplified combination is composed of a drainage tube, a rubber membrane, a miniature nut, a lavage tube, an air-permeable membrane, a three-way unit and a liquid conveying assembly; the rubber membrane sleeves the front end of the drainage tube and is fixed by the miniature nut, the liquid conveying assembly is rotated forwards at first, then the lavage tube is driven to abut against the rubber membrane, then the liquid conveying assembly is started, a small amount of cleaning liquid is drained to exhaust air in the lavage tube into the drainage tube from the air-permeable membrane at an exhaust vent, then the interior of the liquid conveying assembly continues to be rotated, the lavage tube is driven to puncture the rubber membrane for lavage, and the effect of preventing the joint cavity of a patient from being impacted by airflow, and improving the comfort of the patient is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a simplified combination for knee joint cavity lavage. Background technique [0002] Knee arthritis is a chronic disease of knee cartilage degeneration and secondary bone hyperplasia caused by various factors. It mostly occurs in middle-aged and elderly people. , often accompanied by joint effusion, seriously affecting the quality of life of patients. [0003] At present, for knee joint patients with joint effusion, the lavage device is usually used to flush the effusion in the joint cavity, but the existing lavage device has the disadvantage that the air in the lavage tube is discharged into the joint at the moment of liquid medicine flushing. cavity, causing discomfort to the patient. Contents of the invention [0004] The purpose of the present invention is to provide a simplified combination for knee joint cavity lavage, aiming to solve the problem that the air in...
