Electronic blood pressure meter adapted to enable air leakage confirmation to be performed

Abstract

In an electronic blood pressure meter (1), a CPU (40) causes operation for an air leakage test to be performed when a predetermined operation is made at an operating section (3). The CPU uses a pump (21) to force air into a closed space in an arm band (5), said closed space comprising an airbag, an air pipe (10A), and an air pipe (10B), until the closed space reaches a predetermined pressure. Then, the CPU maintains the closed space closed for a predetermined time period and monitors a drop in pressure in the predetermined time period using a pressure sensor (23). When the pressure drops by an amount equal to or more than an allowable value, the CPU determines that there is an air leakage in the closed space comprising the airbag and the air pipes (10A, 10B). Likewise, the CPU causes a closed space comprising the air pipe (10B) to be tested. According to both the test results, the CPU determines whether or not there is an air leakage and whether the portion having the air leakage is in the space comprising the airbag and the air pipes (10A) or in the space comprising the air pipe (10B).

Description

technical field [0001] The present invention relates to an electronic sphygmomanometer, and particularly relates to an electronic sphygmomanometer which wears a cuff with a built-in fluid bag on a measurement site, and uses the change in internal pressure of the fluid bag to measure blood pressure at the measurement site. Background technique [0002] When measuring blood pressure with an electronic sphygmomanometer, a wristband (cuff) with a built-in fluid bag such as an air bag is wrapped around the upper arm / wrist of the person to be measured, and air is fed into the wristband to increase the pressure. Furthermore, in the electronic sphygmomanometer, the guanidine pressure of the person to be measured attached to the wristband is detected as the change in the internal pressure of the air bag, and the blood pressure value is calculated based on the change in the internal pressure. Therefore, if air leaks from the cuff, air tube, etc., which is called an air leak, the guani...

Problems solved by technology

[0008] However, in the method disclosed in Document 1, since the operation of changing the power supply voltage of the electronic sphygmomanometer is required, there is a problem that, for example, when using an electronic sphygmomanometer in general households, it is difficult for users who do not have special skills to use it. In the case of an electronic sphygmomanometer, it is not possible to simply check for air leaks
