Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, in particular to a distal-radial compression device. Background Art
[0002] With the improvement of people's living conditions and the change of working methods, the incidence of cardiovascular diseases has increased year by year, and the corresponding treatment methods, such as interventional therapy, have also been greatly developed and widely used. There are two puncture routes for interventional surgery: the femoral artery and the radial artery. Femoral artery puncture has many inconveniences and disadvantages, so people prefer radial artery puncture intervention.
[0003] Since the compressor is completely pressed against the skin near the radial artery puncture point, excessive pressure will cause ischemia of the surrounding tissues, while too little pressure cannot stop bleeding and may even cause swelling. Existing devices can only stop bleeding for patients but cannot control the appropriate pressure to stop bleeding. It all depends on the doctor's experience, which can easily cause secondary injuries to patients, thereby possibly causing additional pain and other serious consequences to patients.
