FIELD: medicine.SUBSTANCE: invention refers to medical equipment. A blood pressure measuring device under motion activity conditions comprises a pulse wave measurement sensor under a pneumatic cuff in the way of the brachial artery, and a force-balance pulse wave sensor on a diametric side of the hand. Outputs of the measurement and force-balance sensors are attached to respective amplifiers, which are attached to a subtractor, an output of which is connected to a band-pass filter, which is an output of the pressure measuring device. The device is additionally provided with the second band-pass filter, the first and second comparators, the first and second negative threshold voltage source, the first and second gate multivibrators, a logical element 2AND, a shaper for a signal informing on the sensor displacement prohibition.EFFECT: using the invention enables eliminating false responses and blood pressure measurement errors in case of the prohibited sensor displacement by the real-time information acquisition thereon.4 dwg |
