The specific embodiment
As shown in Figure 1, 2, 3:
Main frame 1 connects respectively desk-top control box 2, pedal 3, and pedal 3 places magnetic resonance system 4.
Be provided with in the main frame 1: air pump 15, dc source 16, add pressure electromagnetic valve 5, pressure release electromagnetic valve 6, pressure acquisition device 8:
Be provided with in the desk-top control box 2: pressure display screen 7, add compress switch 11, compression relief cock 12, pressurization display lamp 13, pressure release display lamp 14;
Be provided with in the pedal 3: working plate, substrate, air bag, lifting position-limit switch 10, led status switch 9.
Dc source 16 connect add compress switch 11, compression relief cock 12; Add 11 outfans that compress switch and connect respectively pressurization display lamp 13, lifting position-limit switch 10, lifting position-limit switch 10 connects and adds pressure electromagnetic valve 5, and compression relief cock 12 outfans connect pressure release display lamp 14, and pressure release display lamp 14 connects pressure release electromagnetic valve 6; Air pump 15 connects total power switch 18, pressure acquisition device 8 respectively Bonding pressure display screen 7, add the air bag in pressure electromagnetic valve 5, pressure release electromagnetic valve 6, the pedal 3, and pressure acquisition device 8 respectively with add pressure electromagnetic valve 5, pressure release electromagnetic valve 6 is in parallel; The front end below of the working plate of pedal 3 is connected with air bag, lifting position-limit switch 10 is set on the substrate on the pedal 3, working plate one end is fixed, the other end can rotate around stiff end, lifting position-limit switch 10 is arranged on the high level that working plate rotates, the operation that is working plate is to be that radius rotates by a fixing fulcrum, and lifting position-limit switch 10 is arranged on working plate and turns to a high position (limiting altitude) and locate, and adds pressure electromagnetic valve 5 and connects led status switches 9.
The explanation of this utility model application process:
The power supply lead wire plug of main frame 1 is inserted on the socket of two-phase, three-wire, the connecting pin of desktop control circuit 2 is inserted in the control circuit socket of main frame 1 back, again pedal 3 holding wire connecting pins are inserted in the pedal socket of main frame 1 back.
When the tester in test gastrocnemius when motion, lie on the back at platen (omit, draw) and simultaneously foot be placed on the working plate of pedal 3, fix, to be fixed on shank in the hole of sending into magnetic resonance system 4 on the working plate simultaneously and wait for magnetic resonance examination.
Press the battery main switch 17 on the main frame 1, air pump 15 starts the beginning compressed air; Pressing adding in the control circuit 2 compresses switch 11, makes to add pressure electromagnetic valve 5 energisings and open valve, and the display lamp 13 that pressurizes simultaneously is bright, the airbag aeration of air pump 15 beginnings in the pedal 3, and the working plate of pedal 3 begins upwards to rotate under the air bag extensional process of inside to rise; When the working plate of pedal 3 rotates and reach capacity height, run into the lifting position-limit switch 10 on the substrate, lifting position-limit switch 10 automatically cuts off and adds pressure electromagnetic valve 5, and pressurization stops, led status switch 9 becomes red display lamp by the green indicating lamp of duty, reports to the police.At this moment pressure display screen 7 shows the numeral of pressurization, and with this numeral as basic value, advise the tester with the working plate of self maximum, force pedal 3 and keep firmly and step, numeral on the pressure display screen 7 can increase at this moment, progressively reach maximum pressure, the numeral (being maximum pressure) that shows at last deduct basic value difference 25% be exactly tester institute work (MP).
When test finishes to need pressure release, press the compression relief cock 12 in the control circuit 2, adding simultaneously compresses switch 11 resets, and pressure release electromagnetic valve 6 energisings and open valve, simultaneously pressure release display lamp 14 is bright, and pressure release finishes, and the working plate of pedal 3 returns to initial position.
Pressurization finishes, the patient under doctor's advice according to the working plate of the certain amplitude of trampling pushes pedals 3, magnetic resonance system 4 spectroscopy sequence scanning advises tester's sustain pulse frequency of trying one's best consistent in the scanning process, the speed speed can adhere to finishing 6 minute campaigns and sensation with the patient and reach capacity and be advisable.According to self registering strength, distance, frequency and energy output come determine effect.
Analyzing of applying effects:
As shown in Figure 4: Pi/PCr, gATP/PCr: before the motion and in the motion and in the motion with after the motion significant difference is arranged all; PDE/PCr: in the motion with after the motion significant difference is arranged; AATP/PCr: though before the motion with motion in and in the motion with motion after no difference of science of statistics, P value is near 0.05, continuation enlarged sample amount is to be seen; BATP/PCr, PME/PCr: the motion before with the motion in and the motion in the motion after not statistically significant.After the spectroscopy sequence scanning by magnetic resonance system 4, analyze the ratio of the relative amount of each characteristic chemical substance of gained body, the physiological and pathological that we can dynamically, objectively, accurately and comprehensively be familiar with body changes.The relative prior art of the present invention: first is having more outstanding substance and the innovation on the internal than prior art on the technical characterictic.At first, it has realized magnetic resonance system 4 dynamic acquisition data truly, is a leap than existing technology type dynamic acquisition.Secondly, can objectively show and record tester institute work, existing technical testing person is subjective random large, and strength and the frequency of motion are uncontrollable.Again, adopt antimagnetic material manufacture, than existing technology magnetic resonance system 4 is had more safety: second has significant effect in technological progress.One, more stable than prior art by the present invention's row magnetic resonance imaging data out, repeatability is high.Its two, daily clinical practice Program is simple to operate, the tester easily study with accept, can satisfy clinical a large amount of demands on examination.Its three, the design of diagnosis pedal exquisiteness is that hommization ground uses somatometric result.The platform of pedal allows tested object position, and is comfortable and safe.The pedal that meets the human engineering design.
Because the medical imaging diagnostic device comprises the plurality of devices such as X-ray machine, CT, MRI, wherein MRI is the high-intensity magnetic field diagnostic device, so requiring all auxiliary facilities all must be that nonmetallic materials are made, this utility model equipment is widely used in various medical imaging diagnostic devices, especially more the MRI equipment that is applicable under the strong magnetic field circumstance uses, and this utility model equipment is according to like this condition generation.And the matching requirements volume is little, rises highly highly, and the intensity of pressurized is large, can not cause damage to MRI equipment in the work.The magnetic resonance compatible auxiliary device of measuring the gastrocnemius energy metabolism is to adopt the PP engineering plastics to make, and volume is little, and is lightweight, and ring type stack air bag contracting property is good, be difficult for revealing, and overall safety in the situation of highfield, easy for installation easy to maintenance, be easy to batch production.
