BLOOD PRESSURE ACTUATING APPARATUS AND METHOD DRIVEN BY FLUID AND THEREBY TEST METHOD OF A SPHYGMOMANOMETER

摘要

A blood pressure actuating apparatus, a method driven by a fluid, and a test method of a sphygmomanometer using the same are provided to obtain basic experimental by performing a test for blood pressure actuation under various conditions. A blood pressure actuating apparatus includes a servo valve(100), a pulsation actuating pipe(200), a model arm(300), a second orifice(310), a control pressure sensor(400), a output pressure sensor(500), and a control unit(600). The servo valve switches the supply of a pumped fluid. The pulsation actuating pipe is connected to the servo valve at one side of the pulsation actuating pipe. A first orifice(210) is formed in an end of the other side of the pulsation actuating pipe. One end of the model arm is connected to an input branch pipe(320) branched from a side of the pulsation actuating pipe. An output branch pipe(330) is connected to the other end of the model arm. The second orifice is formed in the output branch pipe. The control pressure sensor measures a pressure generated in the pulsation actuating pipe.
