Multifunctional nuclear magnetic resonance inspection cap

Abstract

A multifunctional nuclear magnetic resonance inspection cap comprises a cap body; the cap body takes the shape of a hollow cover cap; the size and the shape of the cap body enable the cap to wrap and cover the hair growth area, the forehead, the tempora and the ear part of a patient after the cap is worn at the head part of the patient; an elastic structure is arranged on the edge of the cap body; the cap body is made of a flexible material which is unlikey to generate static electricity; an elastic air cushion layer with a gas-filled cavity is arranged on the outer surface of the cap body; the gas-filled cavity is communicated with an external air sac through an air duct; the front part of the cap body is rotationally connected with a cap brim capable of being overturned to cover the eye position to be used as a eye patch. The multifunctional inspection cap has the advantages that the head of the patient can be well fixed during examination; the discomfort such as the noise generated by nuclear magnetic resonance to the patient is reduced; the shielding to eyes is reduced, and the constriction feeling is reduced; the cleanness of the instrument is ensured.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for medical inspection instruments, in particular to a nuclear magnetic resonance multifunctional inspection cap. Background technique [0002] Nuclear magnetic resonance examination is to use the principle of the nuclear magnetic resonance phenomenon that the protons contained in the human body occur in a magnetic field, collect MR signals, and then form an image through spatial coding technology for doctors to make a diagnosis. Because it has completely got rid of the damage of ionizing radiation to the human body, and has many parameters, large amount of information, multi-directional imaging, and high resolution of soft tissues, it has attracted the attention of scholars from all walks of life since its advent. At present, it is widely used in the diagnosis of clinical diseases, and it is an indispensable inspection method for some lesions. [0003] Medical MRI machines are expen...

AI Technical Summary

Problems solved by technology

There are some problems in the existing nuclear magnetic resonance examination: 1. The magnet of the instrument needs to be kept as clean as possible. During the examination, many patients have a lot of inconvenience in cleaning themselves due to factors such as long-term hospitalization, wounds, and the environment. The patient's hair, dirt and Dandruff is easy to deposit in the gap of the inspection instrument during the inspection, which will cause artifacts and affect the image quality

2. MRI requires the patient to have a high degree of cooperation. The shaking of the head and limbs can cause severe movement artifacts and make it impossible to complete the examination. For some patients with impaired self-control ability or patients with forced head positions, appropriate auxiliary fixation is required

At present, the randomly distributed sponge pads are mostly used for filling, and the space filling is not satisfactory enough to effectively prevent the patient's head from shaking

3. The noise of high-field-strength NMR is relatively large, generally between 65 and 95 decibels, and the noise of individual sequences can reach 100 decibels. Although it is within the safe range, it is still unbearable, and a few subjects will experience temporary Tinnitus, temporary hearing loss and other symptoms

4. Subjects suffering from claustrophobia cannot tolerate the narrow space of the magnet, and the panic during the examination cannot be relieved, and symptoms such as palpitation, shortness of breath, and difficulty in completing the examination cannot be completed
