Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
Embodiment 1
According to Fig. 1, a kind of human body simulation standing bed checked for MRI described in the present embodiment, include a body 1, vertically be fixedly connected on a baffle plate 2 of one end, body length direction, described baffle plate is installed with a strain gauge 3, strain gauge is connected with the adjustable drawstring 4 of two adjustable in length, drawstring is connected with the both sides, lower end of a jacket 5.Be connected and fixed by cingulum 6 between jacket front part sides.
Described strain gauge is arranged on the centre position of described baffle plate, and two described drawstrings are connected to the both sides of strain gauge.Described pulling force counts electronic tension meter, has the display screen showing real-time value of thrust above strain gauge.
In order to verify the feasibility of technical solutions of the utility model, spy has carried out following experiment:
Select 10 lumbagos when standing obvious, the clinical signs of suspected waist that during clinostatism, lumbago symptom alleviates is dashed forward disease patient.
Experimental technique:
1, before inspection, whole those who are investigated's scale body weight.And record
2, each example enters to organize those who are investigated, and leading routine lumbar MRI checks: the cross-section position MR of dorsal position TW1, TW2 sagittal plain, TW2 intervertebral disc checks.
3, examine advises those who are investigated to lie on the back in human body simulation to stand examinating couch after completing.
Take a three-stage approach:
The first step adds strong pulling force, when being shown as 1/3 index of those who are investigated's TBW on strain gauge, stops exerting pressure.Observing and be examined whether have sense of discomfort, through feedback, without any discomfort, is exactly the sensation be tightened up.Row heavy burden TW1, TW2 sagittal plain, the cross-section position MR of TW2 intervertebral disc check.
Second step: continue to add strong pulling force, when being shown as 1/2 index of those who are investigated's TBW on strain gauge, stops exerting pressure.Observing and be examined whether have sense of discomfort, through feedback, without any discomfort, is exactly the sensation be tightened up.Row heavy burden TW1, TW2 sagittal plain, the cross-section position MR of TW2 intervertebral disc check.
3rd step: continue to add strong pulling force, when showing 3/5 index of those who are investigated's TBW on strain gauge, stops exerting pressure.Observe and be examined whether have sense of discomfort, through feedback, most of those who are investigated have by too tightly feeling of drawing, and not too adapt to, and wherein have an examined main suit to increase the weight of waist lower limb feeling of numbness.Row heavy burden TW1, TW2 sagittal plain, the cross-section position MR of TW2 intervertebral disc check.
According to above three step MRI check image ratio comparatively:
Simulation is born a heavy burden for the lumbar vertebra heavy burden MRI image of 1/3 index of those who are investigated's TBW, and the image that routine lumbar MRI checks is without any difference, and total negative shows.
Simulation is born a heavy burden for the lumbar vertebra heavy burden MRI image of 1/2 index of those who are investigated's TBW, wherein 5 examples are normal, 5 routine those who are investigated and routine MRI inspection contrast, and prolapse of lumbar intervertebral disc has increasing the weight of in various degree, intervertebral foramina anteroposterior diameter reduces in various degree, wherein unstable 2 examples of lumbar vertebra arrangement.According in conjunction with those who are investigated main suit, similar with erect position symptom, uncomfortable without any other.The situation of lumbar intervertebral disc when energy real simulation is stood.Human body simulation is stood the application of examinating couch, more can react the situation of lumbar intervertebral disc and adnexa thereof really.Reliable diagnosis can be provided for clinical.Clinic is applied.
Simulation is born a heavy burden for the lumbar vertebra heavy burden MRI image of 3/5 index of those who are investigated's TBW, 7 examples increase the weight of for intervertebral disk hernia situation, according in conjunction with those who are investigated main suit, have the probability increasing the weight of prolapse of lumbar intervertebral disc, can not the lumbar vertebra situation of real simulation human body when standing, think and be not suitable for clinical examination.
conclusion:the result prompting of this research, compared with routine MRI, under Weight carrying position MRI can reflect lumbar vertebra physiology and pathological state more objectively, intervertebral disc, intervertebral foramina and lumbar vertebra arrange the situations such as unstable, and the diagnosis that can be lumbar degenerative disease provides reliable basis.
embodiment 2
The difference of the present embodiment and embodiment 1 is: described strain gauge is connected with one in order to adjust the tape mechanism of adjustable drawstring length, tape mechanism comprises the mount pad be fixedly connected on strain gauge, rotating shaft on mount pad is rotatably connected on by bearing, the motor be connected with rotating shaft transmission, and the reel be fixedly connected in rotating shaft, described drawstring is wound on described reel, motor is connected with controller, and controller is connected with power supply and the gauge tap in order to control step motor positive and inverse.The elasticity of adjustable drawstring can be adjusted by tape mechanism easily, improve the work efficiency of doctor, shorten the review time.
embodiment 3
According to Fig. 2, a kind of human body simulation standing bed checked for MRI described in the present embodiment, includes a body, is vertically fixedly connected on a baffle plate of one end, body length direction, baffle plate is connected with the adjustable drawstring of two adjustable in length, drawstring is connected with the both sides, lower end of a jacket; Described bed body is slidably fitted with an individual weight scale 8, described baffle plate has been threaded connection a screw rod 81, screw rod one end and scale are rotationally connected, and the other end that screw rod is positioned at the external side of bed is connected with a swing handle 82.
Compared with embodiment 1, the scheme of the present embodiment does not need the adjustment drawstring adjusting both sides respectively, only needs adjustment swing handle carry out drive screw turns thus scale is moved to patient's upper body direction, patient can be made to be in the state of heavy burden.
embodiment 4
According to Fig. 3, a kind of human body simulation standing bed checked for MRI described in the present embodiment, includes a body, is vertically fixedly connected on a baffle plate of one end, body length direction, baffle plate is connected with the adjustable drawstring of two adjustable in length, drawstring is connected with the both sides, lower end of a jacket; Described bed body is slidably fitted with an individual weight scale, described baffle plate has been threaded connection a screw rod, screw rod one end and scale are rotationally connected, and the other end that screw rod is positioned at the external side of bed is connected with a motor-driven; Be evenly arranged the gas cell of strip along jacket above-below direction inside described jacket, gas cell is connected with air pump, electromagnetic valve by pipeline, air pump, electromagnetic valve and described motor are electrically connected with a controller respectively, and controller is connected with the adjustment button controlling air pump, electromagnetic valve and machine operation.
The present embodiment is inflated the gas cell inside jacket by air pump, and jacket and patient body can be made closely to fix, and when avoiding simulation to bear a heavy burden, patient body produces bending, adds comfort level simultaneously.Moved by control electric machine rotation and adjustable scale, thus the numerical value that increase and decrease is born a heavy burden, easy to operate.
Described scale is electronic scale, and the circuit of electronic scale is connected with controller, and the adjustment button like this by being connected with controller directly sets the vertical of heavy burden, and controller directly controls electric machine rotation and reaches setting pressure to scale.
Use, the experimental technique of embodiment 2-4 are consistent with embodiment 1, again no longer repeat to set forth.
