The first (6) and second (7) synchronous detectors are also used. The first sensor (1) measures resistance along the arteries and veins of the body area, and the second sensor (2) - across the arteries and veins of the same body area. The radio-frequency voltage of the second signal output of the generator (4) is by 90 degrees phase-shifted in relation to the radio-frequency voltage of the first signal output. The first signal output of the generator (4) supplies voltage to current contacts of the first sensor (1), and the second signal output of the generator (4) - to those of the second sensor (2). The potential contacts of the first sensor (1) supply voltage to the input of the first synchronous detector (6); the potential contacts of the second sensor (2) - to the input of the second synchronous detector (7).The control input of the first synchronous detector (6) is controlled by the first signal output of the generator (4); the control input of the second synchronous detector (7) - to the second signal output of the generator (4).

An automatic method for blood pressure signal processing is implemented by means of an automatic device for blood pressure signal processing, which comprises a processing unit. That involves A. sampling a recorded pressure signal P(t) for one or more cardiac contractions. Each cardiac contraction starts at the initial moment coinciding with one of initial points of diastolic pressure, and finishes at the final moment coinciding with the following point of diastolic pressure, and contains a dicrotic point. Each contraction comprises a systolic phase continuing from the initial diastolic point to dicrotic point; B. analysing and identifying the morphology of the pressure signal P(t) sample automatically for each cardiac contraction. A pressure moment and value are determined for one or more characteristic pressure signal P(t) points specified in a group containing: an initial point of diastolic pressure, a point of systolic pressure, a dicrotic point and one or more resonant points, each of which coincides with the moment, when the second derivative d2P/dt2 of the pressure signal P(t) has a local maximum. At least one characteristic pressure signal P(t) point belongs to a systolic phase of the cardiac contraction of interest and differs from the initial point of diastolic pressure. C. determining an energy efficiency RES for each cardiac contraction is ensured by C1. measuring a direct dynamic impedance Zd_D(t) for each of one or more characteristic points belonging to the systolic phase of the cardiac contraction of interest and different from the initial point of diastolic pressure. The direct dynamic impedance Zd_D(t) equals to a relation of the pressure signal P(t) in the characteristic point to a period of time from the initial point of the cardiac contraction of interest to the moment of the above characteristic point. A direct pressure wave impedance ZD is calculated by deriving a reverse-sign sum of the direct dynamic impedances Zd_D(t) pre-ordered in accordance the moments starting from the initial point of the cardiac contraction of interest to the moment of the dicrotic point. The first mechanical dynamic impedance Zd_D(t) in accordance with the moment pre-order is taken with a positive sign. C2. A reflected dynamic impedance Zd_R(t) is determined for each of one or more characteristic points. The reflected dynamic impedance Zd_D(t) equals to a relation of the pressure signal P(t) in the characteristic point to a period of time from the final point of the cardiac contraction of interest to the moment of the characteristic point. A reflected pressure wave impedance ZR is calculated by deriving a reverse-sign sum of the reflected dynamic impedances Zd_R(t) post-ordered in accordance the moments starting from the final point to the initial point of the cardiac contraction of interest. The first reflected dynamic impedance Zd_R(t) in accordance with the moment post-order is taken with a positive sign. C3. The energy efficiency RES is described as a relation of the direct wave impedance ZD to the reflected wave impedance ZR: RES = ZD/ZR. D. For the energy efficiency RES determined at the stage C, it needs verifying if the first derivative dP/dt of the pressure signal P(t) is sure to be less than the first maximum threshold Td throughout the duration of the cardiac contraction of interest, and the second derivative d2P/dt2 of the pressure signal P(t) is sure to be less than the second maximum threshold Td2 throughout the duration of the cardiac contraction of interest. If the verification procedure appears to give a negative result, the stage E is supposed to be performed, whereas the verification with a positive result is followed by the stage F. E. A low-pass filter frequency cut-off is specified in accordance with the energy efficiency RES determined at the stage C, first derivative dP/dt and second derivative dP/dt of the pressure signal P(t). The low-pass filter is applied to the pressure signal P(t) to produce thereby a new pressure signal sample, and the previous stages are performed starting with B. F. The pressure signal P(t) which was the last to processed through the stage B is presented.EFFECT: achieving higher reliability of the blood pressure measurement ensured by dynamic adjustment to blood pressure variability.19 cl, 7 dwg
