Description

A non-contact vital sign detection system with privacy protection

The present invention relates to a non-contact life sign detection system with privacy protection, and more particularly to a field related to non-contact life sign detection with privacy protection.

Nursing is a service that many hospitals or nursing homes attach great importance to. Among them, regular observation of vital signs is the most pressing issue to be improved. If the care recipient feels unwell in a single room and is not discovered immediately, the best golden rescue time will be missed. However, when the care recipient is in a single room, relevant personnel often take the initiative to enter the room to measure the care recipient's vital signs, which will infringe on the care recipient's privacy.

In addition, most of the security monitoring products on the market are based on image capture technology to achieve security monitoring tasks in specific locations or areas. Due to privacy reasons, some places are not suitable for installing monitoring equipment based on image capture technology, resulting in frequent social incidents of hiding in toilets to peek, committing self-mutilation, and waiting for opportunities to commit crimes.

However, monitoring will lead to infringement of personal privacy, but if monitoring devices are not installed in pursuit of personal privacy protection, emergency treatment will not be carried out in the first time when an accident occurs.

In addition, previous security monitoring products required not only power lines for power supply, but also data lines for transmitting image data. The need to configure two types of lines also means more operation time and additional costs.

Therefore, how to design a system that can be set up with privacy-oriented vital signs detection and security monitoring, and how to simplify the configuration of cables, will be the issues and focus of this case.
