Fixing device for auditory meatus examination

Abstract

The invention relates to a fixing device for auditory meatus examination. The fixing device comprises a helmet, and circular through grooves are formed in the two sides of the helmet; a limiting cylinder is mounted at the top of the helmet, a ball is rotatably mounted in the limiting cylinder, a connecting rod is fixedly mounted on the surface of the ball, an external threaded rod is fixedly mounted at the end of the connecting rod, and an internal threaded cylinder is mounted on the external threaded rod; a top plate is fixedly mounted at the top of the internal thread cylinder; the end of the top plate is rotationally connected with a telescopic plate; a guide sleeve is in sliding fit with the exterior of the telescopic plate; the bottom of the guide sleeve is fixedly connected with an L-shaped plate; a guide rod is vertically and fixedly mounted on the vertical section of the L-shaped plate; a pressing plate is in sliding fit with the guide rod; and a lead screw is rotationally installed on the vertical section of the L-shaped plate, penetrates through the pressing plate and is matched with the pressing plate through threads. The head of a subject is fixed and supported through the helmet, so that the head of the subject is prevented from deviating. The effect of adjusting and fixing the head of the subject in the examination process is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a fixing device for ear canal inspection. Background technique [0002] Ear canal examination mainly includes otoscopy, Eustachian tube function test, audiometry test, vestibular function test, fistula test and other tests. During the ear canal examination, the examinee sits on a chair, and the examiner concentrates the reflection of the headlight on an appropriate position, and adjusts the position of the examinee's head so that the opening of the ear canal adapts to the light. After the examiner has adjusted the position of the subject's head, the subject's head is currently supported by the support plate fixed on the chair, but in the actual operation process, there are the following problems in this method: (1) The supporting board cannot effectively support and fix the subject's head, and the subject's head will shift unconsciously during the inspection ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a fixing device for ear canal examination, aiming to solve the following problems in the current ear canal examination when using a support plate to support the examinee's head: (1) The support plate cannot support the examinee's head; During the examination process, the subject's head will shift unconsciously, which will affect the effect of the ear canal examination; (2) The support plate can only support a single head position, and cannot be used during the examination process. Adjust the head position in the middle, the applicability is poor
