Description
Technical field
The present invention relates to a kind of nuclear magnetic resonance fear of confined spaces to be sustained sighting device, belongs to medical inspection ancillary technique field,
In particular to one kind avoids metal material and electricity, magnetic signal interference, realizes stronger visual experience sense by mechanical-physical mode
Nuclear magnetic resonance fear of confined spaces is sustained sighting device.
Background technique
Nuclear magnetic resonance carries out tomoscan to patient tissue using cryogenic magnetic field imaging technique and obtains exact image, is weight
The clinical examination tool wanted.It is the most narrow space of existing nuclear magnetic resonance equipment, closed, it is easy to make patient generate it is nervous with it is frightened
Mood, induce claustrophobia patient fear of confined spaces onset, influence Magnetic resonance imaging quality, even result in inspection and be forced
It interrupts；Nuclear magnetic resonance magnetic field is very powerful, therefore any metallics not can enter scanning area, deep and remote when nuclear magnetic resonance check
It is harsh to close frightened slow release method implementation condition.
Nuclear magnetic resonance check can alleviate examinee's mood by playing music at present, it is contemplated that brain receives five kinds of sense organ letters
The ratio redistribution of breath, visual information up to only account for 11% to the 83%, sense of hearing, disperse examinee's attention effect not by the sense of hearing
Significantly.It can provide background light source inside magnetic resonance detection machine, but be sustained the ineffective of examinee's mood.Nuclear magnetic resonance is put under house arrest
In terms of fear sustained release vision ancillary technique: CN101056577A discloses a kind of medical examination apparatus, installs at the top of diagnosis and treatment hole
Plane mirror simultaneously passes through reflection simulation expantion diagnosis and treatment space, and the nuclear magnetic resonance check of CN201620316994.2 angle adjustable is put under house arrest slow
It releases component and examinee is isolated to the visual perception of examination apparatus internal structure by physical action, the above technical measures vision is presented
Form is dull；CN102648854A discloses a kind of medical examination apparatus, shows carefree image or view by display
Frequency division dissipates examinee's attention, needs to shield the magnetic field of the electronic components such as display；CN201710687294.3 discloses one kind
Putting under house arrest probably for patient is alleviated by virtual reality scenario or eliminated to the image transmission and display unit compatible with nuclear magnetic resonance instrument
Fear disease function, helps patient to smoothly complete nuclear magnetic resonance check, component is various, higher cost.Therefore, one kind is explored simply may be used
It leans on, avoids metal material and electricity, magnetic signal, by physical mechanical mode, the stronger nuclear magnetic resonance fear of confined spaces of visual experience sense
It is sustained sighting device and alleviates or eliminate patient's claustrophobia, help patient to smoothly complete nuclear magnetic resonance check, have very heavy
The meaning wanted.
Summary of the invention
The invention aims to provide a kind of nuclear magnetic resonance fear of confined spaces sustained release sighting device, avoid metal material and
Electricity, magnetic signal interference alleviate fear of confined spaces or nervous Anxiety when nuclear magnetic resonance check by physical mechanical mode.
It is as follows in order to reach the technical solution that the purpose of the present invention is taken:
Convex lens sheet (1) and kaleidoscope (2) coaxial line I are arranged on cabinet (5), the pivot center and axis I of roller (4)
Orthogonal, volume scroll holder (3) coaxial line is attached on roller (4) and with roller (4) forward and reverse rotation, rolls up on scroll holder along volume scroll holder axis
It is evenly equipped with the picture of several same sizes, the picture middle line and axis I vertical with volume scroll holder (3) bus intersect, convex lens sheet
(1), kaleidoscope (2), roller (4) and volume scroll holder (3) form graphic change timing piece；Two groups of identical graphic change meters
When component be symmetrically arranged in cabinet (5), two kaleidoscopes (2) axial line distance is s, two roller (4) coaxial lines are connected, power part
Part (6) passes through two gear (7) variable speed drives, two roller (4) rotations；Cabinet (5) upper surface opens up light-transmitting opening (8), light-transmitting opening
(8) it can provide the required light source of observation volume scroll holder (3), three pieces of rectangle eyeglasses, people's images of left and right eyes be housed inside the kaleidoscope (2)
It moved respectively by two convex lens sheets (1), cooperation volume scroll holder (3), can observe ever-changing figure, it is tested to play sustained release
Person's fear of confined spaces mood and the function of prompting nuclear magnetic resonance check process constitute nuclear magnetic resonance fear of confined spaces and are sustained sighting device；
Wherein, graphic designs cooperation roller (4) revolving speed that scroll holder (3) are rolled up in graphic change timing piece is realized timing and is mentioned
Show function, if nuclear magnetic resonance check duration T, roller (4) revolving speed is ω, chooses pattern number of partitions n appropriate, design volume scroll holder
(3) pattern of figure, tone variations before inspection starts, inform that detected person occurs specific time according to the detection project time
Checking when several, particular color pattern terminates, and graphic change timing piece plays dispersion examinee's fear of confined spaces mood and prompt
The function of nuclear magnetic resonance check process；By known to 2 π of T ω ÷=i...m, 2 π of k=nm ÷: as remainder m=0, i.e. detected person
I-th terminates to check after observing volume scroll holder (3) end pattern；When m ≠ 0, k < 1, k rounding is zero, i.e. detected person's i-th
Inspection is reminded to close to an end after observing volume scroll holder (3) end pattern, when m ≠ 0, k > 1, k is rounded, i.e. detected person's i+1 time
Inspection is reminded to close to an end after observing k-th of pattern of volume scroll holder (3).
The convex lens sheet (1) is camera, convex lens sheet used in VR glasses.
The power part (6) uses the non-metal elastics elements such as clockwork spring, rubber band, before nuclear magnetic resonance check starts,
Power needed for manually providing graphic change timing piece.
Two groups of identical graphic change timing piece distance s, the interpupillary distance that can refer to people carry out size setting,
It can be adjusted according to actual needs.
The nuclear magnetic resonance fear of confined spaces sustained release sighting device is fixed on nuclear magnetic resonance diagnosis and treatment bed using brackets with height-adjustable,
Or measured head is worn on using soft headband；All component materials are all made of nonmetallic materials.
The beneficial effects of the present invention are a kind of nuclear magnetic resonance fear of confined spaces sustained release sighting device proposed passes through machine
Tool mode generates visual pattern variation, and simple and reliable, visual experience sense is stronger, avoids metal, the materials such as light, electricity, magnetic and signal
Interference alleviate putting under house arrest for the enclosure spaces such as nuclear magnetic resonance check by the vision game experiencing in kaleidoscope this childhood
Frightened mood.
