Low-power-consumption multifunctional intelligent blood pressure watch

Abstract

The invention discloses a low-power-consumption multifunctional intelligent blood pressure watch, which comprises a watch head, an air bag, a damping support, an air pump arranged on the damping support, a blood pressure sensor, a body temperature sensor, an infrared lamp, a red light lamp, a sampling chip, an MCU and a communication module, wherein the MCU is a low-power-consumption MCU with a Bluetooth function; the blood pressure watch is in remote communication with a big data center through the communication module; when data does not need to be transmitted to the big data center, the communication module is in a dormant state, at the time, the MCU works independently, and therefore, power consumption can be reduced on the whole; the air bag is provided with a plurality of area blocks, each area block is provided with salient points which are regularly distributed, so that the air bag can be better, deeply and stably in contact with the radial artery, and an oscillatory wave signal can be stably measured. Meanwhile, the blood pressure watch can detect the blood pressure, the heart rate, the blood oxygen and the body temperature and can upload the measured data to the big data center, and the big data center can provide help and intervention services for users with abnormal indexes in time.

Description

technical field [0001] The invention relates to the field of blood pressure watches, in particular to a low-power multifunctional intelligent blood pressure watch. Background technique [0002] A blood pressure watch is an electronic sphygmomanometer that is comparable in size to an ordinary watch and can be worn on the wrist for a long time like a watch. It is mainly measured by a blood pressure sensor and continuously measures blood pressure. The working principle of the blood pressure watch is to add an air bag to the strap of the blood pressure watch. When measuring blood pressure, the air bag is inflated. Through the air bag, the oscillation wave signal of the wrist blood vessels during the air bag filling process is detected. This blood pressure watch enables doctors to understand the wearer's blood pressure changes in detail, detect abnormalities in time, and eventually it will be possible to use these data to predict the time of heart attack.

AI Technical Summary

Problems solved by technology

[0004] 1. The radial artery arrives. The watch is located between the brachioradialis tendon and the flexor carpi radialis tendon. It is difficult to measure the oscillatory wave signal stably through the traditional ordinary airbag, and the traditional ordinary airbag is between the gas filling port of the air pump and the interface of the blood pressure sensor. If the space is not separated, the signal of the blood pressure sensor will be interfered during the air pump filling process;

[0005] 2. There is an air pump inside the watch to inflate the air bag. The inside of the watch must be ventilated with the outside, and there must be air holes. The air holes are easy to enter water. If the user wears the watch for a long time, if the user does not take off the watch when washing hands, the watch may be due to water ingress. and damaged;

[0006] 3. The air pump with a motor is traditionally used. The motor is noisy and shakes strongly when it is working, which makes the user experience poor, especially when it is used at night when sleeping, it will disturb the user, and the vibration generated when the motor is working will interfere with the blood pressure sensor. signal, affecting the measurement accuracy of blood pressure;

[0007] 4. The traditional air pump blood pressure watch uses Bluetooth for communication, which cannot communicate remotely.

And the function is single, usually only one or two indicators of the human body can be measured, and blood pressure, body temperature, blood oxygen, and heart rate are not integrated on the blood pressure watch;

[0008] 5. The traditional air pump blood pressure watch, because the watch has a built-in air pump and blood pressure sensor, these two devices occupy a large space, occupying the space of the watch battery, resulting in a small battery capacity

The main control chip of the 4G watch and the various sensors that detect the physiological indicators of the human body have to work for a long time, resulting in high power consumption and short standby time of the watch
