Abstract:With the vigorous development of biomedical engineering technology, medical signal detection equipment with each passing day. Biomedical detection and clinical medicine and health care is increasingly sensitive to close. Various physiological measurement signals through the human body, can better attention to the phenomena of life of the human body. The pulse contains a lot of information on the status of human health, pulse diagnosis techniques should be quantitative and objective. The design uses a photoelectric sensor to get the pulse signal. The design is mainly based on single chip portable pulse measuring instrument, the use of photoelectric sensors pulse signal after amplifying and shaping, enter the microcontroller internal control corresponding to detect the pulse beats within one minute, very fast and convenient. By observing the pulse, you can check the state of health of the human body, this instrument is often used in hospitals and health centers. The design is based on the C51 single-chip pulse measuring instrument for promoting diagnose the troubles of technology has a positive role in promoting.
