FIELD: medical engineering. SUBSTANCE: device has controllable power supply source for feeding tensometric transducer providing for receiving output signal proportional to relative change in extremity volume. EFFECT: enhanced accuracy of measurements.
Claims (1)
Предлагается устройство для плетизмографии, в котором для питания тензодатчика применен регулируемый источник постоянного тока, позволяющий повысить точность измерения и получить на выходе сигнал, пропорциональный относительному изменению объема конечности.A plethysmography device is proposed in which an adjustable direct current source is used to power the strain gauge, which makes it possible to increase the measurement accuracy and obtain a signal output proportional to the relative change in limb volume.
