Problems solved by technology

However, for applications that only need to monitor short-term changes in blood pressure, this blood pressure monitoring sensor that obtains pulse wave transmission speed based on ECG and blood oxygen signals still needs to arrange ECG monitoring electrodes and blood oxygen probes on the subject. Electronics, so there is still a certain monitoring load for the user, still not comfortable enough

Embodiment Construction

[0032] The disclosure provides a non-contact blood pressure monitoring method and system. Based on video signals obtained from two different parts of the body of the subject, the transmission speed or transmission time of the arterial pulse wave is obtained through image processing technology, thereby realizing non-contact blood pressure monitoring. The continuous, beat-by-beat dynamic measurement of blood pressure improves the user's comfort experience, does not interfere with the user's daily activities, and can provide real-time feedback of the user's blood pressure.

[0033] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0034] In a first exemplary embodiment of the present disclosure, a non-contact blood pressure monitoring system is provided.

Abstract

The invention discloses a non-contact blood pressure monitoring method and system. The non-contact blood pressure monitoring system includes a video signal acquiring module, a blood flow pulse wave signal extracting module and a blood flow pulse wave and blood pressure relationship conversion module; the video signal acquiring module is used for acquiring video signal streams of a first sampling position and a second sampling position on the body of a monitored person; the blood flow pulse wave signal extracting module is used for extracting a transmission speed of pulse waves from the acquired video signal streams; the blood flow pulse wave and blood pressure relationship conversion module is used for converting the transmission speed of the pulse waves into a blood pressure value to dynamically monitoring blood pressure. The system and method can achieve non-contact, cuffless, dynamic, continuous and beat-by-beat blood pressure monitoring, the comfort experience degree of a user is improved, no interference is caused to daily activities of the user, and the blood pressure condition of the user can be fed back in real time.

Description

technical field [0001] The disclosure belongs to the technical field of health care monitoring sensors, and relates to a non-contact blood pressure monitoring method and system. Background technique [0002] With the rapid development of social economy, people pay more and more attention to health status; especially with the increasing aging population and the increasing number of people suffering from chronic non-communicable diseases, real-time monitoring instruments for chronic diseases have become indispensable for medical treatment At the same time, due to other reasons such as inconvenient mobility or shortage of hospital resources, the elderly in each family have a demand for monitoring instruments available at home. [0003] At present, the number of hypertensive patients in our country is increasing day by day. Among the existing household monitoring instruments for hypertension, arm-type or wrist-type ambulatory blood pressure monitoring equipment based on the osci...
