example 1

[0176] Example 1: Non-invasive wrist radial artery blood pressure waveform measurement instrument system

[0177] This instrument system example consists of the following components (such as Figure 16 Shown, each component according to the label):

[0178] (a) A piezoelectric sensor 1a composed of a strain gauge (Strain Gauge), its main body is a 5mm circular sheet (3mm thick), and contains circuits such as signal filtering, amplification, calibration, and temperature compensation. In addition to the circular sensor body, there is another wire connected to the circuit module of the wrist-type physiological monitor host (to be described). The function of the wire is to provide power for the piezoelectric sensor and transmit piezoelectric signals to the circuit module.

[0179] (b) Wrist Physiological Monitor host 2a, which contains air pump, air release valve, standard 2A dry battery (two), RS232 connection port, barometer, and contains central processing unit, memory, and s...

[0189] Example 2: Application of non-invasive wrist radial artery blood pressure waveform instrument system for physiological average blood pressure measurement

[0190] The hardware and software of the instrument, the operation steps, and the healthy volunteers in this example are similar to Example 1, but the piezoelectric sensor is changed from the 5-mm circular body of Example 1 to a 5-mm long one made of ceramic PZT. (along hand length) × 20-mm wide (along hand width) × 2-mm thick piezoelectric element; in addition, an LCD display is added to the wrist-mounted main unit. According to the operation steps of Example 1, obtain the maximum wave height during deflation (the air pressure value at that time was 93mmHg), that is, after step (g) of Example 1, continue to operate the following steps:

[0191] (a) The control and analysis software of the wrist-type main unit takes the occurrence point of the maximum wave height as the reference, and searches for the blood pressure w...

[0196] Example 3: Application of non-invasive wrist-radial artery blood pressure waveform instrument system for heart rate variability and autonomic nervous function measurement

[0197] The instrument hardware of this example is similar to Example 2, but two healthy volunteers participated in the test. In addition, the piezoelectric sensor is changed from the PZT piezoelectric material of Example 2 to the polymer PVDF material, and its shape and size are 5-mm long (along the hand length direction)×20-mm wide (along the hand width direction)×0.5mm thick. In addition, the piezoelectric sensor is pre-installed in the wristband, between the top of the air bag and the outer cloth of the wristband, and its tail connector (Tail Connector, composed of a flexible circuit board) passes through the inside of the wristband and its small The opening, the lower cover of the wrist-type main unit shell, and finally connected to the circuit module in the main unit. The signal processing cir...

Abstract

A non-invasion system for measuring the blood pressure and waveform of arteria radialis on wrist of hand is disclosed. It can be used to monitor blood pressure, variation of cardiac rhythm, automatic nerve function, the waveform and frequency of respiration, cough, sneeze, etc and recognize the identity of person.

Description

technical field [0001] The present invention relates to a measurement system and its application, especially to the measurement of heart rate variation, measurement of autonomic nerve function, personal identification, respiratory waveform and cough detection, home isolation, and hospital isolation. A non-invasive instrument system that uses piezoelectric sensors to measure the blood pressure waveform of the radial artery at the wrist. Background technique [0002] Heart rate and blood pressure (systolic and diastolic blood pressure) are important physiological parameters of the human body. They are generally obtained by existing wrist or arm electronic blood pressure measurement. Due to their easy operation and reasonable price, they have become one of the necessary medical equipment for home use. However, another important physiological parameter, that is, blood pressure waveform, is still not available with high accuracy and easy-to-operate instrument system. [0003] El...
