Hypobaric chamber wearable vital sign monitoring system

Abstract

The invention provides a hypobaric chamber wearable vital sign monitoring system which comprises a coordinator, a PPG terminal, a temperature terminal, a heat preservation device, a PC and an upper computer and is characterized in that the coordinator establishes a sensor network based on a Zigbee protocol and controls terminal work and data transmission; the PPG terminal and the temperature terminal collect PPG signals and multi-point body temperature data; the heat preservation device maintains the working stability of the coordinator under the low-temperature condition of the low-pressure chamber. The PC and the upper computer are used for processing the received data and calculating and storing the oxyhemoglobin saturation, the body temperature, the pulse rate and the breathing frequency in real time. Based on the Zigbee wireless transmission technology, the wearable vital sign monitoring system which can be applied to closed environments such as a hypobaric chamber and the like is provided, the wearable vital sign monitoring system still has good working stability under limiting conditions such as low pressure, high temperature and low temperature, real-time continuous monitoring of oxyhemoglobin saturation, body temperature, pulse rate and respiration is achieved, and the wearable vital sign monitoring system is suitable for being applied to the closed environments such as the hypobaric chamber and the like. The system has the remarkable advantages of low cost, lightness, portability, high expansibility and the like.

Description

technical field [0001] The present invention relates to a vital sign monitoring system, in particular to a low-pressure cabin wearable vital sign monitoring system. Background technique [0002] The changes of vital signs can reflect the abnormal condition of the human body, and are of great significance to the abnormal body function, the prevention and treatment of diseases, etc. At present, the common vital signs monitoring systems mainly include large equipment and small wearable equipment, which can monitor some physiological parameters such as ECG signal, pulse rate, body temperature, blood oxygen saturation, blood sugar, sweat analysis, respiration and many other physiological parameters. The popularity of equipment is not high due to its high cost and large size, while wearable devices are small in size, high in portability, and low in cost. , to meet daily needs. However, in the high and low temperature, low pressure and closed low pressure cabin environment, daily...

Problems solved by technology

However, in the environment of high and low temperature, low pressure and airtight hypobaric cabin, daily wearable devices cannot satisfy the real-time monitoring of multiple vital signs of people in the cabin by people outside the cabin

Traditional wearable monitoring devices generally can only detect ECG signals and calculate heart rate and respiratory parameters. However, under the extreme environmental conditions of the hypobaric chamber, the monitoring of the body temperature and blood oxygen saturation of the tested person is very important for monitoring abnormal physical conditions. Important; in addition, traditional wearable monitoring devices send data based on wireless transmission, and the data transmission in the low pressure cabin will be shielded by the cabin body, which cannot be applied to the monitoring of signs in the specific environment of the low pressure cabin. Under this condition, the data transmission of monitoring equipment without special device protection will be affected and the service life of the equipment will be reduced
