A near-infrared spectrum detection optical fiber connector set

Abstract

The invention discloses a near-infrared spectrum detection optical fiber connector set. The near-infrared spectrum detection optical fiber connector set comprises an optical fiber connector and a self-adaptive optical fiber connector clamping sleeve, wherein the optical fiber connector is provided with a corner with a certain angle; after penetrating into the optical fiber connector, an optical fiber is entirely bent for the angle; the outlet end of the optical fiber connector is in a large chamfered cone shape with certain radian; the self-adaptive optical fiber connector clamping sleeve sheathes the corner of the optical fiber connector and is used for wrapping the optical fiber connector when being fixed with a fixed point of a to-be-detected end so as to protect and package the optical fiber connector; a buffer spring is arranged at the bottom end of the self-adaptive optical fiber connector clamping sleeve to automatically adjust the extension length of the optical fiber connector out of the self-adaptive optical fiber connector clamping sleeve along with the change of external pressure. According to the near-infrared spectrum detection optical fiber connector set, the optical fiber can be conveniently placed to self-adapt to the shape change of the to-be-detected end, partial detection interference is overcome, and the near-infrared spectrum detection optical fiber connector set is applied to emergent light requirements of the optical fiber in spectrum detection equipment and stable connection of the to-be-detected end.

Description

technical field [0001] The invention relates to a near-infrared spectrum detection optical fiber joint set. The optical fiber joint set includes a joint part with a certain rotation angle function and a joint ferrule part with an self-adaptive function. Background technique [0002] In recent years, with the development of near-infrared spectral imaging technology, the research of near-infrared spectral imaging system has made great progress, among which the continuous wave near-infrared spectral imaging system is more prominent. Near-infrared spectroscopy (NIRS) is a non-invasive method for detecting the functional activity of the cerebral cortex. By utilizing the different degrees of absorption of two specific wavelengths of near-infrared light by brain tissue, the measurement of cerebral blood oxygen level can be realized, so that non-invasive, real-time and continuous monitoring can be realized. [0003] Near-infrared brain activity detection equipment often needs to tr...

AI Technical Summary

Problems solved by technology

[0008] (3) Poor self-adaptive ability: it does not have self-regulation ability when it is applied to different detection parts or different detection parts produce small deformation, and has no response to the introduction of errors;

[0009] (4) Poor anti-interference ability: the existing design does not consider the error introduced by the absorption of the emitted light by the hair when detecting the head, and this error is often fatal to the cerebral blood oxygen activity detection equipment, and even makes the detection Signals are completely useless;

[0010] (5) Low service life: Since the optical connector itself has to undertake the task of connecting with the fixing device of the detection end, mechanical wear and tear will inevitably occur during use, and an overly mechanical assembly mode during the installation and disassembly of the connector may easily lead to deformation or even damage of the connector
