Abstract

The invention relates to the technical field of medical electronic equipment, in particular to a sphygmomanometer and a blood pressure measurement method. The sphygmomanometer comprises a processor and at least one blood pressure detection unit, wherein the blood pressure detection unit comprises an airbag, an inflation part, a gas pressure detection assembly and a gas release group; the gas release valve comprises a first gas release valve and a second gas release valve; the passing diameter of the first gas release valve is more than that of the second gas release valve; the gas release valve group is used for receiving a gas release signal emitted by the processor and releasing the air of the airbag; and the processor is used for receiving a pressure signal and calculating a blood pressure value according to the pressure signal. When air pressure detection is carried out in a gas releasing process, the gas is released slowly by adopting the second gas release valve with smaller passing diameter, and the flowing speed of the gas is reduced, and thus, interference of gas flowing on measurement of the pressure sensor is reduced, and the accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of medical electronic equipment, in particular, to a blood pressure monitor and a blood pressure measurement method. Background technique [0002] At present, the common electronic sphygmomanometers on the market use an airbag to pressurize the measuring limb, then collect the pressure signal in the airbag, and calculate the blood pressure value according to the oscillometric method. When measuring blood pressure, generally you can only choose one method of descending blood pressure measurement or ascending blood pressure measurement, that is, measure blood pressure during deflation or inflation. The single measurement mode cannot meet the different needs of users. [0003] Moreover, the pressure in the air bag measured by the common electronic sphygmomanometer shows a step-like change. For the descending blood pressure calculation method, when calculating blood pressure, the pressure based on it ...
