Nuclear magnetic resonance claustrophobic slow-release visual system

Abstract

Belonging to the field of medical examination assistant technology, the invention relates to a nuclear magnetic resonance claustrophobic slow-release visual system. The system consists of: convex lenses, kaleidoscopes, scroll paintings, painting retraction rollers, painting extension rollers, a box body, a winding mechanism, a ratchet wheel, a pawl, a damping disc, light transmission ports. The scroll paintings do counter-clockwise and clockwise rotation along with the painting retraction rollers, and are extended and rolled on the painting extension rollers, torque T is artificially providedto drive the coaxial rotation of the two painting retraction rollers and wind up the winding mechanism, when the scroll paintings are extended at the painting extension rollers and completely reeled at the painting retraction rollers, the ratchet wheel cooperates with the pawl to realize self-locking. The pawl and winding mechanism can be toggled to drive the rotation of the two painting extensionrollers, and under the speed control of the damping disc, the scroll paintings can be extended at the painting retraction rollers and completely reeled at the painting extension rollers simultaneously. Human left and right eyes can observe the ever-changing graphics through the two convex lenses in cooperation with the movement of the scroll paintings, the visual system is simple and reliable, and can avoid the interference of metal, light, electrical, magnetic and other materials and signals, and with the help of childhood kaleidoscope visual game experience, plays the role of slow-release of the claustrophobic emotion of an examined patient.

Description

technical field [0001] The invention relates to a nuclear magnetic resonance claustrophobia slow-release vision system, which belongs to the field of medical examination auxiliary technology, and particularly relates to a nuclear magnetic resonance claustrophobia that avoids the interference of metal materials and electric and magnetic signals, and realizes a stronger visual experience through mechanical and physical methods Slow release of the visual system. Background technique [0002] MRI uses superconducting magnetic field imaging technology to perform tomographic scanning of patient tissues and obtain precise images, which is an important clinical examination tool. Most of the existing nuclear magnetic resonance equipment is narrow and airtight, which can easily cause tension and fear in patients, induce claustrophobic attacks in patients with claustrophobia, affect the quality of nuclear magnetic resonance imaging, and even cause the inspection to be interrupted; the ...

AI Technical Summary

Problems solved by technology

Most of the existing nuclear magnetic resonance equipment is narrow and airtight, which can easily cause tension and fear in patients, induce claustrophobic attacks in patients with claustrophobia, affect the quality of nuclear magnetic resonance imaging, and even cause the inspection to be interrupted; the nuclear magnetic resonance magnetic field is very strong , Therefore, any metal substances cannot enter the scanning area, and the implementation conditions of the claustrophobic mitigation technology during the MRI examination are harsh

[0003] At present, MRI examinations can play music to relieve the examinee's emotions. Considering the proportion distribution of the five sensory information received by the brain, visual information is as high as 83%, and hearing only accounts for 11%. The effect of distracting the examinee's attention through hearing is not significant.

The background light source can be provided inside the MRI detector, but the effect of slowing down the emotion of the examinee is not good

In terms of nuclear magnetic resonance claustrophobia slow-release visual aid technology: CN101056577A discloses a medical inspection equipment, which installs a plane mirror on the top of the diagnosis and treatment hole and expands the diagnosis and treatment space through reflection simulation. The effect is to isolate the subject's visual perception of the internal structure of the inspection device, and the visual presentation of the above technical measures is monotonous; CN102648854A discloses a medical inspection device that displays relaxed and pleasant images or videos on the display to distract the subject's attention, and the display needs to be shielded The magnetic field of electronic components such as; CN201710687294.3 discloses an image transmission and display device compatible with nuclear magnetic resonance equipment, which relieves or eliminates the claustrophobia function of patients through virtual reality scenes, and helps patients successfully complete nuclear magnetic resonance examinations. There are many components, higher cost
