Development of A Newly Monitoring Module for Cardiovascular Hemodynamic Parameters Based on the Blood Volume Pulse

A newly module is developed to monitor cardiovascular hemodynamic parameters continuously and non-invasion by using blood volume pulse.The signal of the blood volume pulse can be detected by the finger tip photoelectric blood volume pulse sensor,then it pass through the signal magnifying and filter circuit,and finally transferred into digital signal used in the microprocessor by means of an A/D converter.The parameters can be worked out by the software in the microprocessor in real-time.The detecting method of the module is non-invasive and operates easily and conveniently,so it can be used in the community and home-care besides monitoring in the hospital.It may also use in the tele-medical by using the Internet technology.
