Blood pressure measuring device based on intelligent cuff

Abstract

The invention discloses a blood pressure measuring device based on an intelligent cuff. The blood pressure measuring device is composed of a cuff outer layer (1), an inner-layer air bag (2), a flexible integrated circuit board (3), a pressure ball (4), a limiting ring (5) and the like, wherein the sensor assembly part of the flexible integrated circuit board (3) is arranged in the inner layer air bag (2); and (3) a power supply module part of the flexible integrated circuit board is arranged outside the inner-layer air bag (2), so that a battery can be conveniently replaced or charged. The flexible integrated circuit board (3) is composed of an MCU controller (16), a pressure sensor (11), an acceleration sensor (12), a microphone sensor (13), an acquisition module (14), a power supply module (15), a transmission module (17) and the like. The blood pressure is measured by acquiring air pressure and pulse sound data in the cuff and adopting a method of combining a Korotkoff sound method and an oscillography method. And the blood pressure is transmitted to terminal equipment through Bluetooth or WIFI or other wireless/wired modes, including but not limited to terminal equipment such as a mobile phone, a tablet computer, a computer and the like (18). The current pressure value and the current blood pressure result are displayed in real time through the terminal equipment, and the pulse pulsation sound can be played and used for judging the Korotkoff sound method. The intelligent sphygmomanometer is the same as a common cuff in appearance, convenient to carry and capable of replacing a traditional mercury sphygmomanometer and an electronic sphygmomanometer.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood pressure measuring device based on an intelligent cuff. Background technique [0002] Noninvasive blood pressure measurement methods mainly include the Korotkoff sound method and the oscillometric method. They are all based on an inflatable air bag cuff, through the process of first blocking the arterial blood flow of the limb by pressurizing it, and then deflated slowly, so that the blocked arterial blood flow can be reopened, and the Korotkoff sound or pulse in the cuff can be detected Oscillating signal to realize the measurement of human systolic blood pressure, diastolic blood pressure, average blood pressure and pulse rate. The typical representative of the Korotkoff sound method is the mercury meter, and the typical representative of the oscillometric method is the electronic sphygmomanometer. [0003] Mercury sphygmomanometer is a kind of Korotkoff-sound...

AI Technical Summary

Problems solved by technology

[0005] The invention proposes a blood pressure measuring device based on an intelligent cuff, which is used to solve the technical defects of the existing Korotkoff-sound method or oscillometric method for measuring blood pressure, and can reduce the interference of external noise on the Korotkoff-sound method and the oscillometric method. Influenced by physical activities during the process, accurately locate the pressure in the cuff corresponding to the moment when the measured arterial blood pressure occurs, and improve the measurement accuracy
