Problems solved by technology

The previous otolith models only have unilateral semicircular canals, which cannot simulate the flow of bilateral otoliths, so the simulation of otoliths is not comprehensive

Embodiment 1

[0080] Example 1: Simulated Dix-Hallpike provocation test and Epley repositioning treatment.

[0081] Dix-Hallpike induced test: magnets were used to attract and fix the other simulated otoliths except the simulated otolith of the right posterior semicircular canal ring, so that the simulated otolith of the right posterior semicircular canal ring could slide freely. Place the human head model in the center and simulate the patient's sitting position. The artificial otolith of the right posterior semicircular canal ring is located at the ampullary end at the bottom of the right posterior semicircular canal ring, then rotate the human head model 45° to the right, and then lie back to the deepest position. Suspend the head so that the human head model and the ground are at about 30°. At this time, the simulated otolith moves away from the ampulla end and flows to the lowest point of the right posterior semicircular canal ring under the action of its own gravity, resulting in chara...

Embodiment 2

[0083] Embodiment 2: Simulation Roll test induces test and BBQ reset treatment

[0084] Roll test induction test: magnets were used to attract and fix other artificial otoliths except the artificial otolith of the right horizontal semicircular canal ring. Allow the simulated otoliths of the right horizontal semicircular canal ring to slide freely. Place the human head model in the middle of the simulated patient's sitting position, and the artificial otolith of the right horizontal semicircular canal ring is located on the bottom foot of the horizontal semicircular canal ring, then lie the human head model down to simulate the patient's supine position, and raise the head and the horizontal plane at an angle of about 30° At this time, turn the human head model 90° to the right to simulate the right turn of the patient's head. At this time, the artificial otolith flows to the lowest point of the right horizontal semicircular canal ring under the action of its own gravity, causi...

Embodiment 3

[0086] Example 3: Simulated side-lying induction test and semont repositioning treatment

[0087] Side-lying induction test: magnets were used to attract and immobilize other artificial otoliths except the artificial otolith of the right posterior semicircular canal ring. The simulated otolith of the right posterior canal ring was allowed to slide freely. Place the human head model in the middle of the simulated patient's sitting position, and the artificial otolith of the right posterior semicircular canal ring is located at the bottom ampullary end, then rotate the human head model 45° to the left, and then lay the human head model to the right to simulate the right side of the patient In the supine position, the simulated otolith of the right posterior semicircular canal ring moves away from the ampulla under the action of its own gravity and slides to the lowest point of the right posterior semicircular canal ring, resulting in characteristic nystagmus. The left posterior...

Abstract

The invention relates to a simulation semicircular canal otolith total head model. The model comprises a head model, a fixation ring, semicircular canal rings used for simulating human semicircular canals, metal collars used for simulating otoliths and magnets. The semicircular canal rings are fixed on the head model according to the positional relationship of 3 pairs of human semicircular canals. Each semicircular canal ring is provided with a metal collar used for simulating the otoliths and a magnet used for fixing the metal collar. Each semicircular canal ring is made of a plastic material. According to another scheme, a transparent tube accommodating transparent liquid is used to simulate a human semicircular canal; a metal ball in the transparent tube is used to simulate an otolith; and the transparent tube is provided with a supporting part. The model provided by the invention simulates three pairs of human semicircular canals on both sides, can simulate all kinds of otolith disease symptoms, and can demonstrate a variety of reduction techniques.

Description

technical field [0001] The invention mainly relates to the field of medical equipment, in particular to a whole-head model of simulated semicircular canal otoliths. Background technique [0002] Otolithiasis, also known as benign paroxysmal positional vertigo (BPPV), refers to short paroxysmal episodes of vertigo and nystagmus that occur when the head moves rapidly to a specific head position. In the inner ear, there is a layer of colloidal membrane on the surface of the utricular plaque and the spherical plaque connected to the semicircular canal. The calcium carbonate particles on the surface of the colloidal membrane are called otoliths. Under normal circumstances, otoliths are attached to the otolithic membrane. When some pathogenic factors cause otoliths to detach, these detached otoliths will swim in the fluid called endolymph in the inner ear. When the head position of the human body changes , the positions of these semicircular canals also change accordingly, and th...
