Technical Field

The utility model relates to the technical field of medical equipment, in particular to pressure measurement formula radial artery hemostasis wrist strap.

Background

According to the yearbook for Chinese hygiene and family planning statistics (2017), the death rate of coronary heart disease of residents in China and rural cities in 2016 keeps on rising trend since 2012. According to the registration data of coronary heart disease interventional therapy of the national health committee, the total number of cases of coronary heart disease interventional therapy in the continental area in 2017 is 753142 cases (including network direct report data and military hospital data), and the increase is 13% compared with 2016. Interventional procedures via the radial approach still represent an absolute advantage (90.89%).
