Wearable measurement device for blood pressure

Abstract

A wearable measurement device for blood pressure comprises a watchband, a valve piece, a gas collecting seat, a gas conveying device, an elastic medium and a pressure sensor, wherein the watchband isprovided with an embedding region, the embedding region is provided with a first containing groove, a second containing groove, a gas collecting through hole and a pressure relief through hole, the gas collecting through hole is communicated between the first containing groove and the second containing groove, and the pressure relief through hole is communicated between the first containing grooveand the exterior of the watchband; the valve piece is overlapped in the first containing groove and provided with a valve hole corresponding to the gas collecting through hole; the gas collecting seat is arranged in the first containing groove, overlapped on the valve piece and provided with multiple holes; the gas conveying device is assembled and seals the gas collecting seat; the elastic medium seals the second containing grooves for inflation elastic displacement; the pressure sensor is arranged on the elastic medium. In this way, guided and conveyed gas is transmitted into the elastic medium, and the elastic medium is inflated with gas to expand to push the pressure sensor to abut against the measurement position of a user so that a blood pressure numerical value can be measured.

Description

technical field [0001] This case is about a wearable device, especially a wearable blood pressure measurement device that combines a gas transmission device with an elastic medium and a pressure sensor. Background technique [0002] In today's society that emphasizes speed and personal pressure is increasing, the awareness of pursuing personal health is gradually developing, so ordinary people will want to monitor or review their own health status on a regular basis. Generally speaking, the traditional data measurement of human physiological health information is mainly through fixed sphygmomanometers or bulky detection instruments. These detection instruments usually include motor-type gas pumps, air bags, sensors, and vent valves. , battery... and other components, it is characterized in that the motor-type gas pump is prone to frictional loss, and the volume of the multiple components assembled is huge, so it is not used frequently, but if it is a smaller motor type If t...

AI Technical Summary

Problems solved by technology

[0006] The main purpose of this case is to provide a wearable blood pressure measurement device with a gas transmission device combined with an elastic medium and a pressure sensor. The piezoelectrically actuated gas transmission device transmits the gas to the elastic medium, inflates the elastic medium, and then transmits the gas through the elastic medium. The pressure sensor arranged at its relative position senses the blood pressure information of the wearer, so as to solve the problems of large size, difficulty in thinning, inability to achieve the purpose of portability, and power consumption of the detection equipment of the known technology. It also solves the problem that the accuracy of the optical detection health monitoring device adopted by another known technology is not high
