Background technique

With the increasingly prominent problem of population aging and the gradual improvement of people's awareness of health. Existing medical services have gradually failed to meet the needs of the public. The most effective way to solve this problem is to shift the focus of medical services downwards and gradually expand from hospitals to community medical centers and families. However, the existing market lacks large-scale medical monitoring instruments that can directly replace hospitals. There is still a certain distance for basic medical care to move from large hospitals to communities, and to families. the

The technical implementation means of the existing physiological information collection equipment mainly use 8-bit single-chip microcomputer as the control core, and use pure analog circuit to condition the signal. For example, wrist sphygmomanometers use relatively backward technical means, resulting in bulky equipment, complex structures, and single physiological parameters that can be collected. At present, with the rapid development of 32-bit mobile processors, high performance, high integration, and low power consumption are synonymous with it, and the price is already at a reasonable and acceptable level. the
