As the rapid increase of the incidence of cardiovascular disease, more and more people begin to realize the importance of detecting and monitoring the cardiovascular function. However, the traditional non-invasive cardiovascular function detecting methods trend to be more expensive, complicated and settled, which are not suitable for real-time and fast detecting. A novel pulse wave collecting and analysis system is designed in this paper to achieve the goal of real-time pulse wave collecting and cardiovascular function detecting, which is portable and easy to use. The MCU used in the proposed signal collector is C8051F320 designed by Silicon Laboratories. A USB-based pulse wave signal collector with appropriately designed I/O interface and peripherals is designed and implemented firstly. Then, an analysis software designed for Personal Computer (PC) is developed based on radial pulse contour characteristic value K method. Finally, the experimental results demonstrate the validity of the proposed system. |
