Embodiment
Below in conjunction with the accompanying drawings and vehicle-mounted CT and ambulance and Physical examination car are further described specific embodiment.
As shown in figure 1, the vehicle-mounted CT 10 in an embodiment, including sweep mechanism 100, fixed frame mechanism 200 and bed boardMechanism 300.The vehicle-mounted CT 10 is used for the head for scanning people.
Sweep mechanism 100 includes scanning cylinder 110, x-ray source 120 and digital imagery plate 130.Scan the edge of cylinder 110First direction 10a extends, for being fixed on car bottom plate.X-ray source 120 it is relative with digital imagery plate 130 be located at scanning drumIn body 110, and line and the first direction 10a at x-ray source 120 and the center of digital imagery plate 130 intersect (it is not parallel, also notOverlap).
Fixed frame mechanism 200 includes the first bedstead seat 210 for being respectively arranged on the relative two ends of scanning cylinder 110 and secondStand 220, the first bedstead seat 210 and the second bedstead seat 220 are used to be fixed on car bottom plate.
Bed board mechanism 300 includes bed board 310.The two ends of bed board 310 respectively with the first bedstead seat 210 and second bedstead seat 220Connection.And bed board 310 can around itself and the rotation of 360 ° of the axis parallel with first direction 10a.
When being CT to head using traditional CT system, people's transfixion, scanning barrel body rotation one is enclosed, so as to drive X to penetrateLine source rotates one with digital imagery plate and enclosed, and then can obtain the CT pictures of the circle of head one.When building traditional CT instruments, sweepRetouching cylinder needs rotation, causes CT equipment instruments big, space-consuming is big, it is impossible to be installed on the cars such as conventional ambulance, Physical examination carOn (height of scanning cylinder is more than the height of inner space), even if being installed on the special vehicle with larger spaceOn, it can not also arrange other Medical Devices (for example, oxygen supply equipment).And in above-mentioned vehicle-mounted CT 10, bed board 310 can be around certainlyBody and parallel with first direction 10a 360 ° of axis rotation, after people is fixed on bed board 310, bed board 310 rotates with peopleOne circle, and when scanning cylinder 110 and maintaining static dynamic, you can obtain the CT pictures that head one is enclosed.Rotated using people, scan cylinder110 modes not rotated, space hold can be reduced to greatest extent, so that CT can be configured on vehicle.Particularly work asWhen above-mentioned vehicle-mounted CT 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 vehicleDuring patient, CT scan can be carried out to it in time, prestissimo obtains scanning result, so as to targetedly medication, mostGold rescue time is utilized to limits, brain damage is reduced, farthest saves life.
In the present embodiment, the inner surface of scanning cylinder 110 is in cylinder.In other embodiments, cylinder is scannedInner surface can also be square.
X-ray source 120 is parallel with vertical direction with the line at the center of digital imagery plate 130, the X that x-ray source 120 is sentRay, so as to reduce radiation of the X-ray to surrounding environment, can be also more convenient for protecting X-ray towards ground or sky.
When people is lain on bed board 310, face upward, when bed board 310 rotates, it may appear that the feelings on the face orientation ground of peopleCondition.In the present embodiment, when people is lain on bed board 310, first people is fixed on bed board 310 with bandage.Bandage can be setIt is calculated as being detachably connected with bed board 310, or independent structure (when in use, it is not necessary to be connected with bed board 310).BandageStructure can be with the bandage of similar sphygmomanometer, it would however also be possible to employ VELCRO makees bandage, and bandage can be with flexible.
Shown as shown in Figure 2, Figure 3 and Figure 4, in the present embodiment, bed board mechanism 300 also includes bedstead 320.Bedstead 320 is wornOn scanning cylinder 110, and the two ends of bedstead 320 are respectively arranged on the first bedstead seat 210 and the second bedstead seat 220, bedstead 320Can around itself and the rotation of 360 ° of the axis parallel with first direction 10a.Bed board 310 is on bedstead 320.Namely in this realityApply in mode, by the way of bedstead 320 is rotated so as to drive bed board 310 to rotate, realize that bed board 310 rotates.It is appreciated that bedFrame can be omitted, and directly rotate bed board.
Specifically, as shown in Fig. 3, Fig. 5 and Fig. 6, in the present embodiment, vehicle-mounted CT 10 also includes the first drive mechanism400a and bindiny mechanism 400b.In the case where the first drive mechanism 400a and bindiny mechanism 400b coordinate, bedstead 320 can around itself andThe axis 360 ° rotation parallel with first direction 10a.
First drive mechanism 400a is including the first motor 410 on the first bedstead seat 210, located at the first motor 410Output shaft on first gear 420 and the second gear 430 that is engaged with first gear 420.Wherein, second gear 430Radius is more than the radius of first gear 420, namely second gear 430 is reduction gearing.Specifically, in the present embodiment, theOne motor 410 is horizontal machine.The rotating speed of second gear 430 can be controlled in 1 second/circle to 120 seconds/circle, and the rotating speed is adapted to quiltExaminer.
Bindiny mechanism 400b includes first connecting rod 440 and second connecting rod 450.The one end of bedstead 320 by first connecting rod 440 withThe center of second gear 430 is fixedly connected, namely first connecting rod 440 is coaxially disposed with second gear 430, so that first connectsThe rotating speed of bar 440 is identical with the rotating speed of second gear 430.The other end of bedstead 320 passes through the bedstead of second connecting rod 450 and second seat220 rotate connection, specifically, the axle sleeve being connected with second connecting rod 450 can be provided in the second bedstead seat 220.
Further, in the present embodiment, bed board 310 10a can also be reciprocated in the first direction, so as to be easy to byPeople is positioned on bed board 310 and is easy to shift people from bed board 310.Specifically, bed board 310 can first be controlled alongOne direction 10a the first bedsteads of direction seat 210 is moved, will so as to (remote to scan at cylinder 110) at the first bedstead seat 210People is positioned on 310；Controlling bed board 310 again, 10a is moved towards the second bedstead seat 220 in the first direction, to make one to be located at scanningIn cylinder 110, to receive the X-ray that x-ray source 120 is sent, CT scan is carried out；After the end of scan, then bed board 310 is controlled to continue10a is moved towards the second bedstead seat 220 in the first direction, so as to (the remote scanning cylinder 110 at the second bedstead seat 220Place) people is shifted from bed board 310.So that when above-mentioned vehicle-mounted CT 10 is configured in Physical examination car, the first bedstead seat 210It can be set respectively with front door at the back door of corresponding Physical examination car with the second bedstead seat 220, Physical examination car above and below convenience.
Specifically, shown as shown in Figure 2, Figure 3 and Figure 4, in the present embodiment, vehicle-mounted CT 10 also include located at bedstead 320 withThe second drive mechanism 500a and the first sliding equipment 500b between bed board 310.Slided in the second drive mechanism 500a and firstUnder motivation structure 500b coordinates, bed board 310 10a can be reciprocated in the first direction.
