DEVICE FOR CHECKING AUTOMATED SPHYGMOMANOMETERS

摘要

FIELD: test equipment. ^ SUBSTANCE: device for checking automated sphygmomanometers can be used for metrological certification of arterial pressure and heart bear rate meters. Device has cylinder simulating human arm, compression cuff of sphygmomanometer to be checked put onto cylinder, operation pressure reference, pressure pulsation source, pressure stabilization unit and control unit. Inputs of control unit are connected with outputs of operation pressure reference device, and outputs are connected with inputs of pressure pulsation source. Tube simulating artery of human arm is disposed in cavity of cylinder simulating human arm. One end of tube is connected with first hydraulic output of pressure pulsation source; other end of tube is connected with input of pressure regulator through operation pressure reference device. Second hydraulic output of pressure pulsation source has to be by-pass channel and it is connected with input of pressure controller which is electrically connected with control unit. ^ EFFECT: improved precision of calibration; reduced time for checking. ^ 2 cl, 1 dwg
