Problems solved by technology

If the equivalent diameter or circumference of the upper arm of the measurement object is larger or smaller than this range, the pressure gap between the cuff airbag pressure 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

[0026] Figure 4 It is a flow chart of the blood pressure data correction method provided by the first embodiment of the present invention. see Figure 4 , the blood pressure data correction method includes:

[0027] S410. Determine the size of the airbag wearing part of the user according to the characteristics of the driving signal of the air pump of the electronic sphygmomanometer, wherein the airbag wearing part is a body part where the user wears the airbag of the electronic sphygmomanometer when measuring blood pressure.

[0028] Electronic blood pressure monitors usually include a balloon 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. Here, we refer to the body part where the user wears the airbag sleeve as the airbag wearing part. The wearing part of the airbag may be the user's wrist or arm. ...

[0047] 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. 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:

[0048] S411. Record the characteristics of the driving signal of the air pump of the electronic sphygmomanometer.

[0049] 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 electronic sphygm...

[0056] 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:

[0057] S421. Calculate the proportional relationship between the pre-stored airbag cuff width and the size of the airbag wearing part of the user.

[0058] The air bag cuff of each electronic sphygmomanometer has a fixed air bag cuff width. The electronic sphygmomanometer stores the width of the air bag cuff as a fixed parameter. After the size of the airbag wearing part of the user is acquired, the ratio between the width of the airbag sleeve as a fixed parameter a...

Abstract

The invention discloses a blood pressure data correction method, a blood pressure data correction device and an electronic sphygmomanometer. The blood pressure data correction method includes: determining size of a part, of a user, wearing an air bag according to a feature of a driving signal of an air pump of the electronic sphygmomanometer, wherein the part of the user refers to the part, of a body of the user, wearing the air bag of the electronic sphygmomanometer when the user measures the blood pressure; correcting the blood pressure data measured by the electronic sphygmomanometer according to a proportional relation between pre-stored width of an air bag sleeve and the size of the part, of the user, wearing the air bag. The blood pressure data correction method, the blood pressure data correction device and the electronic sphygmomanometer have the advantages that blood pressure data can be corrected according to features of different wearing parts of the user, and the blood pressure data measured by the electronic sphygmomanometer can be more accurate.

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] At present, due to its good stability and high reliability, electronic sphygmomanometers are increasingly popular in families, and for reasons of environmental protection and safety, more and more countries prohibit the use of traditional mercury column sphygmomanometers. Electronic sphygmomanometers are widely used in my country. The era of large-scale and widespread application is coming. [0003] figure 1 , figure 2 and image 3 The structure of the existing electronic sphygmomanometer is shown. figure 1 It is a structural schematic diagram of an electronic sphygmomanometer provided by the prior art. see figure 1 , the existing electronic sphygmomanometer comprises air bag cuff 101, deflation valve 102, pressurized air pump 103, ai...
