Problems solved by technology

However, this method cannot judge the movement state of the arm before the measurement starts, so that many measurements start when the arm is active, especially in the ambulatory blood pressure measurement, which will cause many invalid measurements

Embodiment 1

[0015] refer to figure 1 , image 3 , Figure 4 , to illustrate an embodiment of the present invention, such as figure 1 The sphygmomanometer of this embodiment is an integrated upper arm sphygmomanometer, comprising: a cuff 1 containing an airbag 11 and a sphygmomanometer main body 2 for wrapping around the upper arm to measure blood pressure; the sphygmomanometer main body 2 contains a sphygmomanometer control processing unit 20, a motion detection unit 23 , measurement start unit 22 , feedback unit 21 .

[0016] Such as image 3 The sphygmomanometer control processing unit 20 includes a microprocessor 201 , an inflation and deflation control circuit 202 , a pressure sensor 203 , an inflation pump 204 , and an inflation valve 205 . During blood pressure measurement, the microprocessor 201 collects the air pressure value of the airbag 11 detected by the pressure sensor 203 , and controls the pressure of the airbag 11 through the inflation and deflation control circuit 202...

Embodiment 2

[0019] refer to figure 2 , to illustrate an embodiment of the present invention, by figure 2 and figure 1 The difference between embodiment 2 and embodiment 1 is that the sphygmomanometer cuff is separated from the sphygmomanometer main body, but the motion detection unit is still installed on the cuff, and its working process is the same as that of embodiment 1.

Abstract

The invention discloses an electronic sphygmomanometer. The electronic sphygmomanometer has an arm moving state judgement and prompting function before blood pressure measurement and can control whether measurement is started according to the arm state. The sphygmomanometer comprises an upper arm cuff including a motion detection unit, a sphygmomanometer processing and control unit, a pressure detection and control unit, a measurement starting unit and a feedback unit, and the sphygmomanometer processing and control unit, the pressure detection and control unit, the measurement starting unit and the feedback unit are integrated with or split from the upper arm cuff. The sphygmomanometer processing and control unit obtains a signal of the arm state detected by a motion sensor in real time, and when the arm is in a stationary state, starting of once blood pressure measurement is allowed. When the arm is in a moving state, starting of blood pressure measurement is forbidden, the user is reminded in a visual sense, auditory sense or touch sense manner through the feedback unit to keep the upper arm stationary for carrying out blood pressure measurement. At the dynamic blood pressure predetermined measurement moment, if the arm is in a moving state, measurement is carried out in a delayed manner. According to the invention, the blood pressure measurement effectiveness can be improved, especially when dynamic blood pressure measurement is carried out, ineffective measurement generated due to movement of bodies and arms is reduced.

Description

technical field [0001] The invention relates to a sphygmomanometer for measuring the blood pressure of the upper arm of a human body. Background technique [0002] Usually, when blood pressure is measured, the subject is required to start the measurement when the arm is still, and keep the arm in a still state during the measurement process, so as to ensure the accuracy of the measurement. The existing oscillometric blood pressure measurement technology can judge the state of the arm by analyzing the pressure shock wave during detection, and give prompts and error reports when the arm moves. However, this method cannot judge the movement state of the arm before the measurement starts, so that many measurements start when the arm moves, especially in the ambulatory blood pressure measurement, which will cause many invalid measurements. Contents of the invention [0003] The present invention is proposed to solve the problems existing in the above-mentioned prior art. The p...
