Abstract

The invention discloses a full-optical non-contact vital sign monitoring device which comprises a laser light source, a first n*n optical fiber coupler, a first optical fiber, a reference optical fiber, a sensing optical fiber, a second n*n optical fiber coupler, a second optical fiber, an photoelectric detector and a module for extraction and analysis of vital signs, wherein two output ends of the first n*n optical fiber coupler are connected to input ends of the reference optical fiber and the sensing optical fiber respectively; output ends of the reference optical fiber and the sensing optical fiber are connected to an input end of the second n*n optical fiber coupler respectively; an output end of the second n*n optical fiber coupler is connected to the photoelectric detector by the second optical fiber; and an output end of the photoelectric detector is connected to the module for the extraction and analysis of the vital signs. In this way, the full-optical non-contact vital sign monitoring device disclosed by the invention has the advantages that the structure is simple; sensitivity is high; cross infection is avoided; timeliness is high; power consumption is low; distributed remote monitoring is implemented; electromagnetic interference is prevented, etc.

Description

technical field [0001] The invention relates to the technical field of vital sign monitoring, in particular to an MZI-based all-optical non-contact vital sign monitoring device. Background technique [0002] Vital sign monitoring is of great significance to people's daily life and life and health. At present, the monitoring of vital sign signals can be divided into invasive and non-invasive. Intrusive monitoring instruments basically require detectors or sensors to be placed close to the skin or heart of the subject to obtain more accurate information. However, intrusive monitoring instruments are difficult to avoid problems such as cross-infection and anti-electromagnetic interference. Moreover, intrusive monitoring has a greater impact on the comfort of the testee, and the testee may have emotional fluctuations that affect the accuracy of the measurement. [0003] Non-invasive monitoring has great technical advantages. Real-time and accurate monitoring of vital signs can...
