Functional near-infrared device for pushing aside hair in head cap hole

Abstract

The invention relates to a functional near-infrared device for pushing aside hair in a head cap hole. The functional near-infrared device comprises a device ferrule and device deflector rods connected with the device ferrule, wherein the device deflector rods have elasticity; a near-infrared light electrode can be placed in the device ferrule; deflector sheets are arranged at end parts of free ends of the device deflector rods and are L-shaped with the deflector rods; deflector rings are further arranged at inner sides of the device deflector rods and are arranged at positions 1 / 3 away from single sides of the free ends of the device deflector rods, so that the device deflector rods are conveniently operated to be gathered inwards; and in order to conveniently operate the device disclosed by the invention, mounting forceps with forceps rods are further arranged, the forceps rods correspond to the device deflector rods in number and angle, and free ends of the forceps rods are matched with the deflector rings and can be detachably connected with the deflector rings. The device has the advantages that a scalp can be accurately, simply, conveniently and rapidly exposed, the hair is prevented from rebounding, the near-infrared light electrode is rapidly mounted, thus, near-infrared light can be in direct contact with the scalp, interference of the hair to signals is reduced, clinical and scientific researchers can better carry out functional near-infrared related research, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of auxiliary medical equipment, in particular to a device for pulling hair out of a cap hole of a functional near-infrared head. Background technique [0002] Functional NIR assesses neural activity through optical signal changes, which has two core principles. The first core principle is the scattering and absorption of light. After the light passes through the skull, part of the light is absorbed due to the blocking of the brain contents, and the remaining light is scattered. Finally, the light forms an arc-shaped "light path" in the brain and returns to the scalp to indicate that it is received by the receiving light pole. Because HBO, HBR and water absorb different degrees of light, the change of the amount of hemoglobin in the area where the "light path" passes can be obtained by analyzing the changes in the intensity of scattered light. The second core principle is nerve-vascular coupling; neuroscience researc...

Problems solved by technology

[0003] At present, when using functional near-infrared in clinical practice, tools such as ear picks need to be used to remove the hair that blocks the light in order to collect high-quality near-infrared signals. The reason is that the hair will return to its original position and it is not easy to operate

This leads to the need to waste a lot of time on repeated work of picking hair when performing functional near-infrared acquisition, and the rebound of the hair during the work will affect the data quality
