Electronic sphygmomanometer based on TMS320VC5402

Abstract

An electronic sphygmomanometer based on a TMS320VC5402 comprises a DSP module, an A / D conversion module, an external RAM module, a liquid crystal display module, a USB interface module and a power module, wherein the A / D conversion module, the external RAM module, the liquid crystal display module, the USB interface module and the power module are connected with the DSP module. The electronic sphygmomanometer based on the TMS320VC5402 further comprises a signal collection module connected with the A / D conversion module through a filter amplification module. The TMS320VC5402 produced by the TI company is adopted by the DSP module. In-chip resources of a 5402 DSP and the expansion function of a peripheral circuit of the 5402 DSP are fully used by a system, so that the functions that the human body blood pressure is continuously detected, displayed and stored are achieved. The electronic sphygmomanometer is further strong in power management and base line adjusting function. A constant flow source and a temperature compensation method are adopted by a sensor, so that the sensor has the advantages of being high in stability, good in accuracy, low in cost and small in temperature excursion. Therefore, the electronic sphygmomanometer based on the TMS320VC5402 is high in blood pressure measuring accuracy and small in deviation.

Description

technical field [0001] The invention relates to an electronic sphygmomanometer based on TMS320VC5402, which belongs to the field of medical appliances. Background technique [0002] In recent years, with the improvement of living standards and the increase of life pressure, high blood pressure has become the biggest killer of human beings. According to the World Health Organization, the prevalence of hypertension in developed countries has increased by 23%, while in developing countries such diseases have increased by 80%. Blood pressure is an important parameter for people to monitor cardiovascular and cerebrovascular functions, and a sphygmomanometer provides people with intuitive blood pressure physiological information. At present, the measurement technology of sphygmomanometer is mature, and new products of blood pressure detection are springing up in the market. Commonly used blood pressure detection equipment is designed based on single-chip microcomputer, which...
