Description
Technical field
The utility model is related to field of medical technology, more particularly to a kind of X ray checking device and ambulance and physical examination
Vehicle.
Background technology
The elderly because the emergency that cerebral hemorrhage or cerebral embolism cause occupies sizable ratio in all first aid cases of old man,
Cerebral hemorrhage and cerebral embolism can not identify from body surface, and exactly the opposite (cerebral hemorrhage medication is to shrink for cerebral hemorrhage and the medication of cerebral embolism
Blood vessel, reduces bleeding, and cerebral embolism medication is expansion blood vessel), thus can not medication before true disease.
Current way is typically, and first by conveying patient to hospital, then does CT scan in hospital
(Computed Tomography, CT), further according to illness targetedly medication after true disease.And this whole process at least needs two
A hour, the traffic increasingly blocked domestic at present, has delayed gold rescue time in addition, causes cerebral injury to disable, after death etc.
Fruit embodies the meaning that time is life.
In addition, in the 3D rendering scan rebuilding image of CT, utilize monolithic digital imaging plate, and be C arms or G arm more
Rotation, rotation angle are greater than 180 °, cause CT apparatus structures complicated, and required precision is high, and sweep time is long.
Utility model content

Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment carries out furtherly X ray checking device and ambulance and Physical examination car
It is bright.
As shown in Figure 1, Figure 2 and Figure 3, the X ray checking device 10 of an embodiment includes sweep mechanism 100, fixed frame
Mechanism 200 and bed board mechanism 300.It scans on head (target 20) of the X ray checking device 10 for human body.
Sweep mechanism 100 includes along the scanning cylinder 110 of first direction 10a extensions and on scanning cylinder 110
First x-ray source 120, the first digital imagery plate 130, the second x-ray source 140 and the second digital imagery plate 150.First X is penetrated
130 face of line source 120 and the first digital imagery plate, 150 face of the second x-ray source 140 and the second digital imagery plate, and the first X
The center of radiographic source 120 and the line at the center of the first digital imagery plate 130 and the center of the second x-ray source 140 and the second number
The line at the center of word imaging plate 150 intersects, with to the scanning of target 20 positioned at point of intersection.
Fixed frame mechanism 200 includes being respectively arranged on the first bedstead seat 210 for scanning the opposite both ends of cylinder 110 and second
Stand 220.In the present embodiment, the first bedstead seat 210 and the second bedstead seat 220 are for being fixed on car bottom plate.
The both ends of bed board mechanism 300 are rotatablely connected with the first bedstead seat 210 and the second bedstead seat 220 respectively.In this implementation
In mode, bed board mechanism 300 can be around the rotation of 360 ° of the central axes of itself.
When being CT to head using traditional CT system, people is stationary, and scanning barrel body rotation one encloses, to drive X to penetrate
Line source and one circle of digital imagery plate rotation, and then the CT pictures of the circle of head one can be obtained.When building traditional CT instruments, sweep
It retouches cylinder to need to rotate, causes CT equipment instruments big, occupied space is big, cannot be installed on the vehicles such as common ambulance, Physical examination car
On (height of scanning cylinder is more than the height of inner space), even if being installed on the special vehicle with larger space
On, it can not also arrange other Medical Devices (for example, oxygen supply equipment).And in above-mentioned X ray checking device 10, bed board mechanism
300 can rotate, and after people is fixed on bed board mechanism 300, bed board mechanism 300 is rotated with people, and is scanned cylinder 110 and maintained static
It is dynamic.It is rotated using people, the mode that scanning cylinder 110 does not rotate can make the structure of X ray checking device 10 simple, maximum
The reduction space hold of limit, so that above-mentioned X ray checking device 10 can be configured on vehicle.Especially when above-mentioned X is penetrated
When ray detection device 10 is configured on the vehicles such as ambulance, Physical examination car, the cerebral hemorrhage for needing to give treatment to or cerebral embolism are connected in vehicle
When patient, CT scan can be carried out to it in time, prestissimo obtains scanning result, so as to targetedly medication, most
Gold rescue time is utilized to limits, cerebral injury is reduced, farthest saves life.
And in above-mentioned X ray checking device 10, by the way that first and second two groups of x-ray sources and digital imagery is arranged
