Detection device for measuring pulse and heart rate based on PVDF piezoelectric sensor

Abstract

The invention provides a detection device for measuring the pulse and the heart rate based on a PVDF piezoelectric sensor. The detection device comprises a pressure-sensitive module, a control module,an adhering part and a shell, wherein the pressure-sensitive module is fixed to one side of the adhering part, the control module and the shell are fixed to the other side of the adhering part, the shell is used for protecting the control module, the pressure-sensitive module is connected with the control module through a lead, the side, fixing the pressure-sensitive module, of the adhering partcan be adhered to the skin for measuring the pulse and the heartbeat, the pressure-sensitive module comprises a PVDF piezoelectric film, the PVDF piezoelectric film measures the pressure generated bythe pulse and the heartbeat, converts a pressure value corresponding to the pressure into an electric signal, and transmits the electric signal to the control module, and the control module generatespulse and heart rate detection data based on the electric signal. The detection device is convenient to use, and can reliably and accurately measure the pulse and the heart rate of a user.

Description

technical field [0001] The invention relates to medical detection technology, in particular to a detection device for measuring pulse and heart rate based on a PVDF piezoelectric sensor. Background technique [0002] Pulse, heart rate frequency and waveform contain important physiological information of the human body, which to a certain extent reflect the health status of the human body and the pathological characteristics of the cardiovascular system, so they are an important source of information for diagnosing cardiovascular physiological conditions. Through the analysis of pulse and heart rate data, some indicators of the heart can be obtained indirectly, such as diastolic tension, contraction force, sealing of arterial valves, and elasticity of blood vessel walls. In medicine, the method of using the pulse to diagnose diseases has a long history. The pulse diagnosis in traditional Chinese medicine and the examination of cardiovascular diseases in Western medicine large...
