[0029] See also Figure 1-7As shown, a mobile CT inspection device of the present invention includes a base 1, a plurality of universal wheels 2 are installed at the bottom of the base 1, and a scanner 3 is installed on the base 1, a scanning port 4 is opened on the scanner 3, and an X-ray tube 5 and a detector array 6 are installed on the top and bottom of the scanning port 4 respectively. The X-ray tube 5 and the detector array 6 are both existing technologies and can be purchased directly from the market. The X-ray tube 5 can generate an X-ray beam to pass through different tissues in the patient's body. The detector array 6 can capture the X-rays after passing through the body and convert them into electrical signals and transmit them to the computer. After receiving the signals transmitted by the detector array 6, the computer uses complex algorithms to process the data and convert the 2D projection data into a 3D volume image to complete image reconstruction. The reconstructed image can display the cross-section or three-dimensional structure inside the patient's body. The processed image is displayed on the screen by the computer for analysis by radiologists and other medical staff. The top of the base 1 is fixedly connected to a support base 7. The top of the support base 7 The bed 8 is fixedly connected to the end of the bed 8 near the scanning port 4. The bracket 9 is L-shaped and a headrest 10 is fixedly connected to the top of the bracket 9. When a CT examination is required, the patient can lie flat on the bed 8 and lean his head against the top of the headrest 10. A storage cavity 11 is provided at the other end of the bed 8. An expansion board 12 is provided in the storage cavity 11. One end of the expansion board 12 is fixedly connected to a handle 13. When the patient is tall, the expansion board 12 can be taken out of the storage cavity 11 by holding the handle 13. The overall length of the bed 8 can be extended, thereby greatly improving the scalability of the CT examination device, making it suitable for patients of different heights and body shapes. To accommodate patients of different body shapes, detachable safety belt slots can be added to the side of the bed 8 for use with medical-grade restraints. When the expansion plate 12 is pulled out, the restraints can be passed through the slots to secure the patient's torso. This design is a conventional medical equipment accessory with mature technology and no complex structure. Positioning mechanisms are provided on the front and rear sides of the support base 7.

[0030] The positioning mechanism includes an electric telescopic rod 14, which is installed on the base 1. The bottom end of its output shaft passes through the base 1 and is fixedly connected to a positioning plate 15. The positioning plate 15 is located below the base 1. The position of the CT inspection device can be moved by the universal wheels 2 at the bottom of the base 1. When the movement is completed, the electric telescopic rod 14 is driven to drive the positioning plate 15 downward until the positioning plate 15 contacts the ground. At this time, the CT inspection device can be effectively positioned by the positioning plate 15 to prevent it from slipping and displacement during use.

[0031] Among them, a number of anti-slip pads 16 are provided on the bottom surface of the positioning plate 15. The anti-slip pads 16 are long strips and are equidistantly distributed linearly along the length direction of the support seat 7. The surface of each anti-slip pad 16 is engraved with a herringbone anti-slip pattern. When the positioning plate 15 contacts the smooth ground, the anti-slip patterns on the surface of each anti-slip pad 16 can increase the friction between the positioning plate 15 and the ground to play an anti-slip role, thereby further improving the positioning effect of the positioning plate 15.

[0032] Among them, the width and thickness of the expansion plate 12 are respectively equal to the width and height of the storage cavity 11, and the front end face and the rear end face of the expansion plate 12 are fixedly connected with a screw 17, and the front side and the rear side of the storage cavity 11 are provided with a slide groove 18, and the groove width of the slide groove 18 is equal to the diameter of the screw 17. The screw 17 passes through the slide groove 18 and extends outside the storage cavity 11, and the screw 17 is threadedly connected with a nut 19 that matches it. When the expansion plate 12 moves, it will drive the screw 17 to slide along the slide groove 18. At this time, the mutual cooperation between the screw 17 and the slide groove 18 can play a limiting role, so as to improve the stability of the expansion plate 12, thereby preventing it from shaking and tilting. By tightening the nut 19, the position of the expansion plate 12 can be fixed to complete the expansion and adjustment of the overall length of the bed body 8.

[0033] Among them, a pair of armrests 20 are fixedly connected to the top of the bed body 8, and the armrests 20 are respectively located on the front and rear sides of the bed body 8, and the armrests 20 are provided with anti-slip covers 21. The surface of the anti-slip covers 21 is engraved with herringbone anti-slip grooves. When the patient lies flat on the bed body 8, he can hold the armrests 20 with both hands to avoid accidentally falling off the bed body 8. The anti-slip grooves on the surface of the anti-slip covers 21 can increase the friction between the human hand and the armrest 20 to prevent slipping and falling off.

[0034] Among them, the head support 10 is located between the X-ray tube 5 and the detector array 6, and a bracket 22 is provided on the top of the head support 10. The bracket 22 is an arc-shaped groove structure, and the centers of the bracket 22, the X-ray tube 5 and the detector array 6 are located on the same straight line. When the patient's head rests on the top of the head support 10, it can fit in the bracket 22. At this time, the X-ray tube 5 and the detector array 6 can face the head, thereby ensuring that the scanner 3 can accurately scan the patient's head image.

[0035] Among them, a number of reinforcing ribs 23 are fixedly connected to the top of the bracket 9. The reinforcing ribs 23 are triangular, one side of which is fixedly connected to the side wall of the bracket 9, and the reinforcing ribs 23 are equidistantly linearly distributed along the width direction of the bracket 9. The reinforcing ribs 23 can support and reinforce the bracket 9 to improve the structural firmness of the bracket 9, thereby effectively avoiding deformation of the bracket 9 after being subjected to stress for a long time.

[0036] The circuits, electronic components and chip modules involved in the present invention are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0038] The working principle of this utility model is:

[0039] When the present invention is in use, the position of the CT inspection device can be moved by the universal wheels 2 at the bottom of the base 1. After the movement is completed, the electric telescopic rod 14 is driven to drive the positioning plate 15 to move downward until the positioning plate 15 contacts the ground. At this time, the CT inspection device can be effectively positioned by the positioning plate 15. When a CT inspection is required, the patient is allowed to lie flat on the bed 8 and lean his head against the top of the headrest 10 so that it fits into the bracket 22. At this time, the X-ray tube 5 and the detector array 6 are facing the patient's head. Then, the X-ray tube 5 at the top of the scanning port 4 can generate an X-ray beam to pass through the patient's head tissue. The X-rays that pass through the head can be captured by the detector array 6 and converted into electric The signal is then transmitted to a computer. After receiving the signal transmitted by the detector array 6, the computer uses a complex algorithm to process the data and convert the 2D projection data into a 3D volume image to complete image reconstruction. The reconstructed image can display the cross-section or three-dimensional structure of the patient's body. The processed image is displayed on the screen by the computer for analysis by radiologists and other medical staff, thus completing the entire CT examination operation. When the patient is tall, the expansion plate 12 can be pulled out of the storage cavity 11 by holding the handle 13. At this time, the overall length of the bed 8 can be lengthened after expansion. The position of the expansion plate 12 can then be fixed by tightening the nut 19 to complete the expansion and adjustment of the overall length of the bed 8.
