Process control system for standardized blood pressure measurement and implementation method

A process control system for standardized blood pressure measurement, comprising a blood pressure measurement process control device having a built-in control module, a display screen, a control switch and an electronic sphygmomanometer, and the control module is configured to control the entire measurement process, and the display and output of the results;

• the display screen is configured for human-computer interaction and display of the measurement results;
• the control switch is configured to control the startup and shutdown of the electronic sphygmomanometer;
• the electronic sphygmomanometer is configured to realize blood pressure measurement, and is mounted inside the blood pressure measurement process control device through a fixed structure;
• the control module comprises an information acquisition module, an image clarity detection module, a data processing module and a blood pressure measurement process control module, wherein the information acquisition module is configured to take pictures of the user's identity document information and the information on the display panel of the electronic sphygmomanometer each time, and send the collected image to the image clarity detection module;
• the image clarity detection module is configured to carry out the clarity detection for the collected image, and send the qualified image to the data processing module;
• the data processing module comprises an image preprocessing module, a text detection module, a text recognition module and a regex filtering module, the image preprocessing module is configured to crop the document image according to specifications and correct the image taken by the electronic sphygmomanometer display panel, the text detection module and the text recognition module are configured to detect and recognize the textual information in the document image and the blood pressure measurement result image, the regex filtering module extracts and fills the key information of the text by specifying the corresponding regex filtering standard, the data processing module identifies and extracts the sampled data, further calculates the average and difference values of the blood pressure measurement readings, integrates the user's identity information with the blood pressure measurement results, and then displays it on the display screen;
• the control command signal of the control switch is regularly sent out by the built-in program of the signal acquisition module, the virtual switch is driven by the I/O control card connected through the USB interface to replace the traditional manual start button, and a set of standardized double-arm synchronous blood pressure measurement of the patient is realized by controlling the electronic sphygmomanometer under the built-in program.
