Embodiment Construction

[0088] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0089] In the prior art, it is generally considered that the diastolic and systolic pressure coefficients are constant. However, according to clinical research, these two coefficients will be affected by the tightness of the air bag winding. If this factor is not considered, it may cause The accuracy of blood pressure calculation results decreases; when the air bag is coiled too tightly, under the same basic air pressure, the air pressure pulsation amplitude is...

Abstract

A blood pressure calculating method for an electronic sphygmomanometer, a device, and an electronic sphygmomanometer. The method comprises: measuring a pressure value in an air bag, and obtaining a sequence of air pressure values in the air bag (S101); collecting and acquiring a PWM instruction sequence of a drive air pump at the same time, and acquiring an air pressure pulse sequence and a basic air pressure sequence on the basis of the sequence of the air pressure values (S102); generating an envelope line matching the air pressure pulse sequence (S103); calculating a tension level coefficient of the air bag (S104); correcting a systolic pressure coefficient and a diastolic pressure coefficient according to the tension level coefficient (S105); and calculating a systolic pressure and a diastolic pressure of a user on the basis of a characteristic of the envelope line and the adjusted systolic pressure coefficient and the diastolic pressure coefficient (S106). The invention resolves the issue of low measurement accuracy caused by inconsistency of a tension level of an air bag.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an electronic sphygmomanometer blood pressure calculation method and device for improving blood pressure measurement accuracy, and an electronic sphygmomanometer. Background technique [0002] Sphygmomanometers are one of the most commonly used medical equipment tests. Electronic sphygmomanometers using the oscillometric method have been on the market for many years. This type of sphygmomanometer wraps an air bag around a certain part of the human body and adjusts the air pressure in the air bag to collect data on changes in internal pressure and calculate the systolic / diastolic blood pressure of the subject accordingly. [0003] By controlling the air pump and air valve and other components, the air bag can be inflated / deflated, so that the air volume in the air bag changes, which further causes the air pressure in the air bag to change. The air pressure change caused ...
