摘要：
The invention relates to medical engineering and can be used for daily monitoring of blood pressure in a free motor activity of man. The apparatus comprises measuring and compensating pulse wave sensors. The measuring sensor is located under the pnevmomanzhetoy in a place of passage of the brachial artery. Compensation sensor is identical to the measuring sensor and is located symmetrically on the diametrically opposite side of the arm. measuring and compensating pulse wave sensor outputs are connected to the respective amplifiers, the gains of which are chosen from the condition of equality of the amplitude of the output signal from the amplifier with the same physical effects on both sensors. The outputs of the amplifiers are connected to a subtractor whose output is connected to the input of a bandpass filter. The device provides a time offset spurious signals arising from the sensors offset for that output compensating sensor through sequentially included bandpass filter connected to the inverting input of the first comparator, and an output pressure meter - to the inverting input of the second comparator, the non-inverting inputs of the first and second comparators filed negative threshold voltage, the comparator outputs through the series-connected monostable multivibrator 2I connected to inputs of NAND gate whose output is connected to the signal generating apparatus of informing inappropriate displacement sensors and via an inverter to the input of the multiplier, allowing passage of beneficial and prohibiting passage of spurious signals.Use of the device will improve the accuracy and reliability of determining systolic and diastolic blood pressure values, including motor activity in a human.Полезная модель относится к медицинской технике и может быть использовано при суточном мониторировании артериального давления в условиях свободной двигательной активности человека.
