Unattended vital sign monitoring device

Abstract

The invention discloses an unattended vital sign monitoring device. The device comprises an encryption part and a decryption part, the encryption part comprises a respiratory radar sensor, a first ARM minimum system and a first trusted computing module TCM, and the decryption part comprises a second ARM minimum system and a second trusted computing module TCM. According to the invention, communication between the ARM processor and the respiratory radar module can be realized, and related vital signs (such as blood pressure, heartbeat, sleep depth, sleep breathing rate and the like) and behavior state (such as off-bed state, body movement and the like) data of a detected person can be detected; and a running environment communication security mechanism is established through a trusted computing technology to safely upload the data to an application platform for processing and analysis, and related guardians can be reminded to take intervention measures in time if abnormity occurs.

Description

technical field [0001] The invention relates to the field of sleep quality monitoring, in particular to an unattended vital sign monitoring device. Background technique [0002] In the existing market, there are some vital sign monitoring devices or products, but their application scenarios are different. Some of the existing products are listed below and their advantages and disadvantages are briefly analyzed: [0003] (1) Smart wearables: such as smart bracelets, sticky RFID, etc. to collect and analyze people's pulse, breathing rate, exercise status, etc., to judge people's behavior and sleep conditions. The main disadvantage is that it is an intrusive device, Bluetooth, 4G or WiFi communication, data transmission on the Internet, no dedicated data encryption hardware, and data security is not guaranteed. [0004] (2) Smartphone applications: The main disadvantages are that the effect is not accurate, cannot be used without the mobile phone, Bluetooth, 4G or WiFi communi...

AI Technical Summary

Problems solved by technology

The main disadvantage is that it is an intrusive device, Bluetooth, 4G or WiFi communication, data transmission on the Internet, no dedicated data encryption hardware, data security is not guaranteed

[0004] (2) Smartphone applications: the main disadvantage is that the effect is not accurate, cannot be used without the mobile phone, Bluetooth, 4G or WiFi communication, data transmission on the Internet, no dedicated data encryption hardware, data security is not guaranteed

The advantage is that there is no need to wear it, and the comfort is high. The disadvantage is that there are certain security risks in the power supply method, Bluetooth or WiFi communication, data transmission on the Internet, no special data encryption hardware, and a low data security level.

[0006] (4) Polysomnography (PSG): PSG is a comprehensive sleep test commonly used in medicine. It is mainly used for clinical diagnosis of sleep disorders (sleep apnea, narcolepsy, periodic limb movement disorder, etc.), high cost, and direct Contact with the human body creates certain constraints on the human body and is not suitable for real-time online monitoring

[0007] (5) Bio-radar sensors based on millimeter waves: This type of equipment is mainly installed under bedside tables and mattresses, and can monitor data such as sleep duration, sleep depth, and breathing rate. The advantages are high judgment accuracy, wide coverage, and good real-time performance. Strong penetration ability, etc., but it is also installed in an easy-to-reach place, Bluetooth or WiFi communication, the software is deployed in a mobile phone or public network environment, there is no special data encryption module, data security is not guaranteed, and it is not suitable for application in physical environments and scenarios with high data communication security requirements

[0008] Among the above-mentioned devices or products, millimeter-wave-based bio-radar sensors are widely used due to their advantages of high judgment accuracy, wide coverage, good real-time performance, strong penetrating ability, and non-contact, etc., but they lack the guarantee of data security. Disadvantages make it less suitable for places with high security requirements
