Inflation and deflation control method for blood pressure measurement, control system and device

Abstract

When an inflation and deflation control method provided by the invention is used in a blood pressure measurement process, the original pressure signal of a cuff is acquired in real time while the cuffis inflated, and whether the blood pressure calculation condition is met or not is judged in real time according to the original pressure signal. If the original pressure signal is judged to meet theblood pressure calculation condition, the cuff is immediately deflated after the blood pressure value is calculated; and if the original pressure signal is judged not to meet the blood pressure calculation condition, the cuff is deflated and the blood pressure is measured by adopting a pressure reduction method. According to the method disclosed by the invention, a uniform inflation pressure value is not required to be set, but the cuff is immediately deflated after the cuff pressure state meets the blood pressure calculation condition, or effectiveness of measurement data is ensured by taking a pressure reduction measurement method as a supplementary link. The inflation and deflation control method can shorten the blood pressure measurement time and improve the comfort of a tested person. The invention also relates to a related device for executing the control method and an inflation / deflation control system.

Description

technical field [0001] The present application relates to the technical field of medical equipment, and in particular to a method for controlling inflation and deflation for blood pressure measurement, a medical device and a computer-readable storage medium for performing the method, a system for controlling inflation and deflation for blood pressure measurement, and a blood pressure measuring instrument , Plug-in parameter measurement modules and monitors. Background technique [0002] Electronic sphygmomanometer is a relatively common blood pressure measuring device at present. Its working principle can be divided into boost pressure measurement method (also called inflation measurement) and step-down pressure measurement method (also called deflation measurement) according to the measurement method. The boost measurement method uses an air pump to inflate and pressurize the cuff, and uses the inflatable cuff to compress the arterial blood vessel. As the cuff pressure rise...

Problems solved by technology

This inflation and deflation mode has the following disadvantages: (1) When the blood pressure of the subject is higher than the current inflation pressure value, it cannot meet the measurement needs of blood pressure, resulting in one or more repeated inflation and deflation actions, which increases the measurement time and gives The patient brings additional discomfort, and even leads to measurement failure; (2) When the subject is hypotensive and his current blood pressure is significantly lower than the inflation pressure value, the inflation pressure value is set too high, which will cause the subject to Bearing too much unnecessary pressure load can easily cause physical discomfort, and at the same time increase the measurement time of the subject
