Non-contact vital sign data monitoring system and non-contact vital sign data monitoring method

Abstract

The invention relates to a non-contact vital sign data monitoring system and a non-contact vital sign data monitoring method. The monitoring system comprises a video acquisition unit, an image processing unit, a temperature monitoring unit and an output unit. Preferably, vital signs include temperature and / or respiratory frequency; preferably, the video acquisition unit and the output units are intelligent terminals, and the image processing unit is an intelligent terminal with a photographing function; and particularly, a monitoring function of vital sign data is achieved through a smart phone or a tablet personal computer with the photographing function and the temperature monitoring unit. Compared with a traditional vital sign data acquisition system, the system is free of dependence on instrument contact, high in portability, accuracy and sensitivity and extremely wide in application range.

Description

technical field [0001] The invention relates to monitoring vital sign data, in particular to a non-contact vital sign data monitoring system and monitoring method. Background technique [0002] Vital signs are an important indicator to reflect the health status of the human body. play an important role in medical practice. With the advancement of modern medical methods and the rapid development of mobile medical care, single-point measurement of human health status through portable devices has become a hot spot. In this context, the monitoring of vital signs is undoubtedly an ideal research object. [0003] However, at present, the collection of vital signs is still mainly in the form of contact, with the help of sensors to sense changes in human vital signs, such as body temperature, heart rate, and respiratory rate. The drawbacks of such a method are obvious. On the one hand, it requires people to wear relevant sensors, which limits the range of measurement; on the oth...

AI Technical Summary

Problems solved by technology

On the one hand, it requires people to wear relevant sensors, which limits the range of measurement; on the other hand, it also brings inconvenience to people's normal life, and even causes varying degrees of damage to the human body in the long run

[0004] The commonly used non-contact vital sign data monitoring system, such as Chinese patent application 201110325533.3, reports a non-contact vital sign monitoring method and monitoring system based on video images, but it cannot intelligently track test subjects during the implementation process. The position of the subject needs to be selected manually; more importantly, for this traditional monitoring method, it can only realize the monitoring of a single individual's vital signs once, but cannot realize the simultaneous monitoring of multiple individuals

In addition, such an implementation cannot be well embedded into smart terminals, and it is difficult to be widely used in daily life
