Electronic blood pressure meter and method for controlling same

Abstract

A blood pressure meter (1) is provided with: an air bag (13) which is to be mounted to the part of a person at which blood pressure is to be measured; a pressure sensor (23); a pump (21) which adjusts inner pressure; a valve (22); drive circuits (26, 27) for both the pump (21) and the valve (22); a CPU (40) which is connected to the pressure sensor and the drive circuits, controls the adjustment of the inner pressure, and performs processing for calculating a blood pressure value on the basis of the change in the inner pressure which occurs during the adjustment; and a holding section (11) from which, and into which, fluid can flow into and out of the air bag and which has a smaller capacity than the fluid bag. When a predetermined pressure is applied to the holding section, the fluid can flow out of the holding section into the air bag. The CPU starts the adjustment of the inner pressure when a change in pressure within the air bag is a change specified in advance, the change in pressure within the air bag being detected by the pressure sensor before the start of the adjustment of the inner pressure.

Description

technical field [0001] The invention relates to an electronic sphygmomanometer and a control method thereof, in particular to an electronic sphygmomanometer for measuring blood pressure with an air bag and a control method thereof. Background technique [0002] As one of daily management of patients in medical facilities, blood pressure management of patients can be cited. In this blood pressure management, the basic biological information of each patient is measured at short intervals (usually 2.5 minutes to 5 minutes) during the operation, or the blood pressure is measured periodically (for example, 2 to 3 times / day) during the hospitalization process, so as to grasp The patient's circulatory status. [0003] In operating rooms and wards, sphygmomanometers are usually installed at places several meters away from patients, such as the head side and foot side of the hospital bed. Therefore, a measurer such as a medical practitioner needs to move to the side of the sphygmom...

Problems solved by technology

[0006] However, this device has the problem that the device itself is expensive

[0007] In addition, there is a problem that the user's workload increases due to management of the remote control body, wrapping the air bag around the upper arm, etc., and taking out the remote control to operate it.
