Title: SPHYGMOMANOMETER
Abstract:
A sphygmomanometer, comprising: a strap that is wrapped around the wrist or arm of a user, an elastic band being provided on the strap; at least two stacked airbags (1, 2, 3) are fixed between the strap and the elastic band, the at least two stacked airbags (1, 2, 3) being provided with an air pump air port (10), which is used to connect to an air pump on a main machine, a sensor air port (20), which is used to connect to a sensor on the main machine, and a solenoid valve air port (30), which is used to connect to a solenoid valve that is on the main machine and that is used for deflation. Air pressure detected by the sensor is air pressure which is buffered and filtered by means of the airbags (1, 2, 3); since the at least two layers of airbags (1, 2, 3) increase the volume, the pressure within the airbags (1, 2, 3) may be ensured to linearly increase such that the pressure detected by means of the sensor air port (20) is more accurate, thereby improving the accuracy and stability of the sphygmomanometer.
