Terminal Design of Nontouch Queryable Photoelectric Pulse Oximetry

Aimed at monitoring dynamic human pulse and blood oxygen saturation for physical fitness, health care and other fields, a nontouch queryable photoelectric pulse oximetry terminal was designed. The terminal uses a transmission type oxygen probe to collect information of pulse and blood oxygen saturation, uses a low power consumption, low cost STC12C5A16AD microcontroller for analysis and processing of these achieved information , and uses a nRF2401 wireless communication chip for construction of nontouch queryable communication mechanism. The users in the gym or nursing home can query up to 255 terminals and get the real-time monitoring information. Through the experiments, this terminal can effectively provide pulse and blood oximetry saturation monitoring data, can meet the daily physical fitness, health care and other non medical application requirements
