Description

a monitoring bracelet

technical field

The utility model relates to a monitoring component, in particular to a monitoring bracelet.

Background technique

At present, China is facing a huge population aging pressure, and the issue of old-age care has become a hot topic of concern to the whole society. Therefore, more and more attention has been paid to the health status of the elderly, monitoring of daily activities and medical care. However, due to the increase in single-child and empty-nest families, most elderly people cannot receive timely monitoring and cannot detect accidents in daily life of the elderly living alone, such as abnormal body temperature, unstable heart rate, and inability to get up after falling. Therefore, if a smart bracelet can be developed to monitor the health status and daily activities of the elderly in real time, so as to achieve the purpose of timely detection and early prevention, it can bring security to the healthy life of the elderly. At present, there are many kinds of smart bracelet products on the market, some can only measure the state of exercise, and some can measure a variety of physiological parameters, including ECG, pulse, body temperature, exercise state, etc. However, most of the products have the following problems: (1), the collected data cannot be transmitted to the remote service system, and the data cannot be stored and analyzed for a long time; (2), there is a timely data transmission function, but due to the large power consumption of collection and transmission , requires frequent charging. Chinese patent CN202589516U discloses a wearable ECG sensing electrode, including a conductive pressure sensor, a flexible rod and other structures, which can eliminate the impact of motion on ECG detection by analyzing the state of motion and the degree of motor contact, and realize real-time Monitor ECG to improve the ability of early prevention, timely detection and timely treatment of heart-related diseases. However, it needs to be attached to foreign objects. When there is no suitable external object to attach to, it is easy to be in stable contact with the skin, making it difficult to perform effective ECG detection. The processing equipment processes the detected signals, the steps are complicated and cumbersome, and the detection results cannot be displayed in real time; when the detected skin is sunken downward, the conductive cloth cannot make effective contact with it; and its function is single, it can only detect ECG signals, Body temperature and pulse signals cannot be detected, and the range of use is valid.

Therefore, the utility model proposes a smart bracelet for the elderly care system, which collects the heart rate information of the elderly through a non-contact photoelectric sensor, collects the body temperature of the elderly through a non-contact temperature sensor, and collects the running posture of the elderly through a six-axis acceleration sensor. Algorithms are used to detect whether the elderly have fallen. The ultra-low power consumption Bluetooth chip NRF51822 is used as the main processor for sensor data analysis and Bluetooth communication. The wristband also has a clock display function and an automatic time calibration function. In terms of the design of the shape of the bracelet, it is completely designed according to the structure of the watch, which is convenient for the elderly to carry. According to the data, at present, there are no reports on smart wristbands that can detect the physical signs of the elderly around the clock, and smart wristbands that integrate heart rate, body temperature, fall prevention, automatic time adjustment, and clock display.
