Human body pulse wave waveform signal generation device

Abstract

A human body pulse wave waveform signal generation device comprises a central controller, a heart rhythm generation unit, a heart ventricle blood pumping waveform generation unit, an artery blood flow characteristic simulation unit, a heart rhythm synchronous interface unit and a linear transformation unit. The central controller is connected with all the other units and is used for controlling operation of all the other units. The heart rhythm generation unit is used for generating trigger signals according with the human body heart rhythm characteristic. The heart ventricle blood pumping waveform generation unit is used for generating heart ventricle blood pumping waveforms according with the human body heart ventricle blood pumping characteristic. The artery blood flow characteristic simulation unit can simulate the human body artery and blood flow characteristic through an appointed model and calculates pulse wave waveform signals. The human body pulse wave waveform signal generation device can generate the multi-cycle dynamic continuous pulse wave waveform signals reflecting multi-aspect factor influences, the waveforms are vivid, parameters are rich and adjustable, and therefore the human body pulse wave waveform signal generation device has strong expandability and can well meet requirements of pulse wave related equipment detection and correction.

[0004] A kind of " digital pulse wave signal generator " disclosed by CN201012085U and a kind of " detection method of Korotkoff sound delay time and pulse wave transit time blood pressure monitor and the signal generator applying it " disclosed by CN100466968C all lack pulse wave Waveform signal generation device, but only download the pulse wave waveform data used by it from an external computer

CN103054564A disclosed "A Generator and Method for Pulse Wave Waveform Based on FPGA" adopts a double elastic cavity model to generate pulse waves under four conditions of low resistance and medium resistance. According to medical knowledge, the pulse wave of the human body is mainly regulated by nerves , ventricular pumping characteristics, arterial characteristics, blood flow characteristics and other factors, this method only considers the influence of arterial characteristics, which is not comprehensive, which leads to the fact that the pulse waveform generated by this method cannot fully meet the realistic and objective requirements

For these tested devices, this method will not be able to provide pulse waveforms containing relevant detection parameters

There are also many pulse wave-related devices that can analyze indicators such as human heart function and neuromodulation function by detecting pulse waves, and this method cannot provide pulse waveforms containing relevant detection parameters for these devices.
