Problems solved by technology

If the equivalent diameter or circumference of the upper arm of the measured object is greater than or smaller than this range, the pressure difference between the cuff airbag and the brachial artery pressure will be relatively large, so that there will be a large gap between the blood pressure measurement result and the actual situation. Improve

[0045] see Figure 4 , Figure 4 It is a flow chart of the blood pressure data correction method provided by the first embodiment of the present invention, and the blood pressure data correction method includes:

[0046]S410, estimating the size of the user's airbag wearing part according to the characteristics of the driving signal of the air pump of the electronic blood pressure monitor, wherein the airbag wearing part is the body part where the user wears the airbag of the electronic blood pressure monitor when measuring blood pressure.

[0047] An electronic sphygmomanometer usually includes an airbag cuff. When a user uses an electronic sphygmomanometer to measure blood pressure, he usually wears the airbag cuff on a certain part of his body, and then measures the user's blood pressure by pressurizing the airbag cuff. blood pressure. Here, the body part where the user wears the airbag sleeve is referred to as the airbag wearing part, and the airbag wearing part may be t...

[0067] Figure 5 It is a flowchart of body part size determination in the blood pressure data correction method provided by the second embodiment of the present invention.

[0068] The blood pressure data correction method is based on the first embodiment of the present invention. Further, in the blood pressure correction method, determining the size of the user's airbag wearing part according to the characteristics of the driving signal of the air pump of the electronic sphygmomanometer includes:

[0069] S411. Record the characteristics of the driving signal of the air pump of the electronic sphygmomanometer.

[0070] In the electronic sphygmomanometer, the microprocessor is connected with the air pump driving circuit, and the pressurized air pump is driven to work through the air pump driving circuit. Since the air pump driving circuit drives the pressurized air pump under the control of the microprocessor, the characteristics of the air pump driving signal of the electron...

[0077] Image 6 It is a flow chart of blood pressure data correction in the blood pressure data correction method provided by the third embodiment of the present invention. The blood pressure data correction method is based on the first embodiment of the present invention. Further, the blood pressure measured by the electronic sphygmomanometer is adjusted according to the proportional relationship between the pre-stored airbag cuff width and the size of the user's airbag wearing part. Data corrections include:

[0078] S421. Calculate the proportional relationship between the pre-stored airbag cuff width and the size of the airbag wearing part of the user.

[0079] The airbag cuff of each electronic sphygmomanometer has a fixed width of the airbag cuff, and the electronic sphygmomanometer stores the width of the airbag cuff as a fixed parameter. After obtaining the size of the user's airbag wearing part, calculate the fixed parameter The ratio between the airbag sleeve width...

Abstract

The invention discloses a blood pressure data correcting method, a blood pressure data correcting device and an electronic sphygmomanometer. The sizes of air bag wearing parts of users are determinedaccording to the features of drive signals of an air pump of the electronic sphygmomanometer, meanwhile, correction is carried out on blood pressure data measured by the electronic sphygmomanometer according to the prestored proportional relation between the width of an air bag sleeve and the size of the air bag wearing part of the user, so that for the electronic sphygmomanometer, correction canbe carried out on the measured blood pressure data according to the features of the air bag wearing parts of the different users, thus the accuracy of the blood pressure data measured by the electronic sphygmomanometer is improved, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of electronic sphygmomanometers, in particular to a method and device for correcting blood pressure data and an electronic sphygmomanometer. Background technique [0002] Due to its good stability and high reliability, the current electronic sphygmomanometer is becoming more and more popular in families, and for reasons of environmental protection and safety, more and more countries prohibit the use of traditional mercury column sphygmomanometers. The era of large-scale and extensive application in our country is coming. [0003] figure 1 , figure 2 and image 3 The structures of conventional electronic sphygmomanometers are shown respectively. figure 1 It is a structural schematic diagram of an electronic sphygmomanometer provided by the prior art. see figure 1 , the existing electronic sphygmomanometer includes an airbag cuff 101, a deflation valve 102, a pressurized air pump 103, an air pump drive ...
