Description

A radial artery compression hemostat

technical field

The invention belongs to the technical field of medical devices, in particular to a radial artery compression hemostat.

Background technique

With the improvement of people's living conditions, the incidence of cardiovascular diseases is increasing year by year. The radial artery puncture intervention method has become the main method for the treatment of coronary heart disease. Local bleeding or hematoma is the focus of postoperative care. However, the pressing time is relatively long. Manual pressing is time-consuming and tiring for the presser, and the pressure is not easy to control. If the pressure is too small, there will be insufficient pressure and bleeding. If the pressure is too high, it will easily cause poor blood flow or even ischemia; The tightness is not easy to control when bandaging, which affects venous return. Some patients tend to have swelling and pain in their hands when bandaging is too long, resulting in ischemic injury, prolonging the time of patients staying in hospital for observation and increasing the burden on patients. Many tightening devices are bonded with Velcro. When the tightness of the restraint needs to be adjusted, the Velcro needs to be torn and re-glued. In the process of tearing, the hemostatic effect will be affected due to the release of the restraint. Technically, a compression airbag is installed in the bandage body to increase the pressure to improve the hemostatic effect, but when the compression airbag is inflated, air leakage at the nozzle of the air intake tube is easy to affect the required pressure of the airbag.
