Abstract

The present invention relates to a new-type insertion valve and other artificial valve in-vitro performance testing equipment. Said equipment includes the following several portions: pulsopump, a segment of artificial blood vessel, power system, variable temperature system and resistance system. Said invention also provides the connection mode of all the above-mentioned portions, and also provides the concrete operation method of said equipment.

Description

technical field [0001] The invention belongs to the field of medical equipment. Background technique [0002] Heart valve disease is one of the major heart diseases at present, and has various etiologies such as rheumatic, degenerative and congenital, and the only treatment for most patients with valve disease is artificial valve replacement. The research on artificial heart valves began in the 1950s, which can be divided into mechanical valves and biological valves. With the emergence of artificial valves, people must understand the performance of valves before performing valve replacements. Correspondingly, a device that can be used for in vitro performance testing of valves has been developed. The research on artificial valves in my country began in 1965, and for The systematic research on the valve performance testing device began in the 1980s. Tsinghua University developed a series of systems for valve performance testing in vitro. quality testing standards. With the g...
