Abstract

The invention discloses a simplified combined device for lavage of the knee joint cavity, which is composed of a drainage tube, a rubber membrane, a miniature nut, a lavage tube, a breathable membrane, a three-way tube and a liquid delivery component. The rubber membrane Sleeved on the front end of the drainage tube, and the miniature nut is fixed, first turn the liquid delivery assembly to the front end, and then drive the irrigation tube to resist the rubber membrane, start the liquid delivery assembly, and discharge A small amount of cleaning liquid discharges the air in the lavage tube from the air-permeable membrane at the vent hole into the drainage tube, and then continues to rotate the liquid delivery assembly to drive the lavage tube to puncture the rubber membrane Lavage can prevent the patient's joint cavity from being impacted by the airflow and improve the patient's comfort.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a simplified combined device 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 combined device for knee joint cavity lavage, aiming at solving the problem of di...
