Blood pressure parameter detection method and user terminal

Abstract

A user terminal UE (100) includes: a memory (102) storing executable program codes, a first ECG contact (103), a second ECG contact (105), and the first ECG contact (103) and The ECG detection circuit (106), the PPG detection point (104) connected with the second ECG contact point (105), the PPG detection circuit (107) connected with the PPG detection point (104); and the memory (102), the ECG detection circuit ( 106) and the processor (101) coupled with the PPG detection circuit (107); the processor (101) calls the executable code stored in the memory (102), and performs the following steps: through the first ECG contact (103) and the second The ECG contact (105) detects the user's ECG signal, wherein the first ECG contact (103) and the second ECG contact (105) form a pair of detection electrodes; after judging the detected ECG signal and the prestored reference ECG signal In the case of matching, start the PPG detection circuit (107), and detect the user's PPG signal through the PPG detection point (104); when it is judged that the detected PPG signal matches the pre-stored reference PPG signal, start the blood pressure detection application , and obtain the user's blood pressure parameters through the detected ECG signal and PPG signal.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a blood pressure parameter detection method and a user terminal. Background technique [0002] Among the existing terminal products for measuring blood pressure using the measurement method of pulse wave transit time (PWTT), such as the combination product of tablet computer and sphygmomanometer or the combination product of smart phone and blood pressure detection mobile phone case, users are using this type of When a terminal product measures blood pressure, the following operations generally need to be performed: Unlock the master device → open the application → establish a communication connection with the slave device → select parameters (for example, select a user) → start the measurement → put your hand on the measurement point according to the prompts, and then the device can The measurement is completed and the measurement result is displayed. [0003] The inventors...

Problems solved by technology

[0003] The inventors of the present invention found during the research process that, on the one hand, the above-mentioned blood pressure measurement scheme is complicated to operate, the steps are cumbersome, and it is difficult to learn and master, and the objects of blood pressure measurement are often mainly elderly people, and it is difficult for the elderly to quickly learn and master The above blood pressure measurement method

On the other hand, in the existing blood pressure detection scheme, the terminal device can also collect relevant signals and output blood pressure parameters when the user does not touch the detection point stably, which affects the accuracy of the detection results of blood pressure parameters
