Device and method for automatically controlling blood occlusion of carotid artery

The invention discloses a device and a method for automatically controlling blood occlusion of the carotid artery. The device is formed by an installation base plate, a slide support, an air pressure blocking module, an air pressure control module and n wireless blood oxygen measurement modules. The air pressure control module is installed in an air pressure control module guide groove of the slide support which is arranged in a slide support guide groove of the base plate. The air pressure blocking module is positioned below the air pressure control module and connected with the air pressure control module into a whole. The wireless blood oxygen measurement modules are used for calculating blood oxygen values. A single-chip microcomputer in the air pressure control module receives the blood oxygen values measured by the wireless blood oxygen measurement modules through wireless communication circuits, collects pressure of pressure sensors and automatically controls pressurization and pressure reduction of air pressure of the air pressure blocking module. The air pressure control module and single-chip microcomputers in the blood oxygen measurement modules control air pressure and blood oxygen measurement according to program control processes. By means of the method adopting wireless communication, structural design is simplified, redundant wire connection is eliminated, and the device is scientific, reliable, practical and good in effect.
