Problems solved by technology
[0003] Due to the low detection accuracy of the long-term pulse detection device in the past, and the inability to display whether the measurement point is the best measurement point, there will be some operational errors in some pulse measurement, and there will be some deviations between the output results and the actual required results value
At the same time, because it is a contact measurement, and the temperature will have a certain impact on the output of the piezoelectric pulse sensor, some instruments have no specific compensation for the temperature, and the measurement environment is also limited.

The invention discloses a long-term and self-checking position pulse detector and a pulse detection method thereof. The detection accuracy of the traditional long-time pulse detector is not high, andwhether a measurement point is an optimal measurement point can not be displayed. The long-term and self-checking position pulse detector comprises a pulse sensor, an information amplification transmission circuit, an interactor, a controller and a tightness adjuster, wherein the pulse sensor comprises a detection shell, n transverse piezoelectric thin film strips and n longitudinal piezoelectricthin film strips; the n transverse piezoelectric thin film strips and the n longitudinal piezoelectric thin film strips are sequentially arranged and staggered in a grid shape in the detection shell;and the n transverse piezoelectric thin film strips and the n longitudinal piezoelectric thin film strips are connected with the controller through the information amplification transmission circuit.The invention can prompt a user to adjust the position of the pulse sensor so as to improve the detection precision and improve the precision of the current detection result in a displacement compensation mode.
Description
technical field [0001] The invention belongs to the technical field of biological detection, and in particular relates to a pulse detector and a pulse detection method for measuring a patient's pulse by utilizing the accurate and reliable properties of a piezoelectric film. Background technique [0002] The development of piezoelectric materials is not only in the machinery manufacturing and mechanical testing industries. With the advent of different materials, piezoelectric films have gradually become the main body of piezoelectric materials. As an important physiological characteristic of human beings, pulse is produced by the periodic beating of the heart, which drives blood circulation, changes the volume and pressure in the aorta, and causes the vibration of the arterial wall. The period and frequency and intensity of the pulse can indicate the physiological state of some people. So the detection of the pulse was born here. [0003] Due to the low detection accuracy o...
