Abstract
A blood pressure detection method is provided. The method comprising: obtaining wrist circumference data, wrist fat thickness data, and blood pressure data and correcting the blood pressure data based on the wrist circumference data and the wrist fat thickness data.
Claims20
A method, comprising:
- obtaining, by a wearable device, wrist circumference data, wrist fat thickness data, and blood pressure data of a user wearing the wearable device, wherein obtaining the wrist circumference data comprises:
- detecting an electrical parameter of an adjustable component around a wrist of the user, wherein the adjustable component comprises at least one of an adjustable resistor, an adjustable capacitor, or an adjustable inductor;
- and
- determining the wrist circumference data based on the electrical parameter;
- determining, based on the wrist circumference data, at least one wrist circumference threshold, the wrist fat thickness data, and at least one wrist fat thickness threshold, whether the blood pressure data needs to be corrected, comprising:
- when the wrist fat thickness data is less than a first wrist fat thickness threshold, and the wrist circumference data is less than a second wrist circumference threshold, determining that the blood pressure data does not need to be corrected;
- when the wrist fat thickness data is less than the first wrist fat thickness threshold, and the wrist circumference data is greater than the second wrist circumference threshold, determining that the blood pressure data needs to be corrected;
- and
- when the wrist fat thickness data is less than a second wrist fat thickness threshold and greater than the first wrist fat thickness threshold, and the wrist circumference data is greater than a first wrist circumference threshold and less than the second wrist circumference threshold, determining that the blood pressure data needs to be corrected;
- and
- when it is determined that the blood pressure data needs to be corrected, correcting, by the wearable device, the blood pressure data based on both the wrist circumference data and the wrist fat thickness data.

- a main body;
- one or more processors;
- one or more memories, wherein the one or more processors and the one or more memories are disposed in the main body, wherein one or more computer programs are stored in the one or more memories, the one or more computer programs comprise instructions, and when the instructions are executed by the electronic device, the electronic device is enabled to perform:
- obtaining wrist circumference data, wrist fat thickness data, and blood pressure data of a user wearing the electronic device, wherein obtaining the wrist circumference data comprises:
- detecting an electrical parameter of an adjustable component around a wrist of the user, wherein the adjustable component comprises at least one of an adjustable resistor, an adjustable capacitor, or an adjustable inductor;
- and
- determining the wrist circumference data based on the electrical parameter;
- determining, based on the wrist circumference data, at least one wrist circumference threshold, the wrist fat thickness data, and at least one wrist fat thickness threshold, whether the blood pressure data needs to be corrected, comprising:
- when the wrist fat thickness data is less than a first wrist fat thickness threshold, and the wrist circumference data is less than a second wrist circumference threshold, determining that the blood pressure data does not need to be corrected;
- when the wrist fat thickness data is less than the first wrist fat thickness threshold, and the wrist circumference data is greater than the second wrist circumference threshold, determining that the blood pressure data needs to be corrected;
- and
- when the wrist fat thickness data is less than a second wrist fat thickness threshold and greater than the first wrist fat thickness threshold, and the wrist circumference data is greater than a first wrist circumference threshold and less than the second wrist circumference threshold, determining that the blood pressure data needs to be corrected;
- and
- when it is determined that the blood pressure data needs to be corrected, correcting the blood pressure data based on both the wrist circumference data and the wrist fat thickness data.
