Wrist-arm type electronic sphygmomanometer and method for measuring blood pressures

Abstract

The invention discloses a wrist-arm type electronic sphygmomanometer and a method for measuring blood pressures. The wrist-arm type electronic sphygmomanometer comprises a wrist and arm band air channel interface, a pressure sensor, a microcontroller, an air pump control circuit, an electromagnetic valve control circuit and a display screen. The wrist and arm band air channel interface is connected with wrist bands or cuffs, the pressure sensor is connected with the wrist and arm band air channel interface, the microcontroller is connected with the pressure sensor, and the air pump control circuit, the electromagnetic valve control circuit and the display screen are respectively connected with the microcontroller. The wrist-arm type electronic sphygmomanometer and the method have the advantages that the wrist and arm band air channel interface is shared by the wrist bands or arm bands, whether the blood pressures of users are measured via the wrist bands or the arm bands at the moment can be judged by the aid of the microcontroller, corresponding measuring programs can be executed according to judgment results, accordingly, the users can select preferred measurement modes for measuring the blood pressures, and multipurpose effects can be realized.

Description

technical field [0001] The invention relates to an electronic sphygmomanometer, more specifically, to a wrist-arm electronic sphygmomanometer and a method for measuring blood pressure. Background technique [0002] With the continuous improvement of people's living standards and the increase in the proportion of aging people, people's self-care awareness is gradually enhanced, and arm-type electronic sphygmomanometers and wrist-type electronic sphygmomanometers have been widely used. Wrist-type electronic sphygmomanometers are convenient to measure, but because of The pulse of the elderly is relatively stiff, and the measured blood pressure will have certain errors, so it is not very suitable for the elderly to use. Although the arm-type electronic sphygmomanometer is accurate, it needs to expose the upper arm when measuring, which is not very convenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a w...
