DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0035] Example 1

[0036] The present invention provides a movable scanning bed of medical CT equipment and a method of using the same. Figures 1 to 6 As shown, it includes a base 1, a connecting frame 2 is fixedly installed on the top of the base 1, a movable frame 3 is movably connected to the top of the connecting frame 2, the base 1, the connecting frame 2 and the movable frame 3 are combined into a scanning bed, and a lifting component 4 is fixedly installed on the bottom of the base 1;

[0037] The lifting assembly 4 includes two mounting frames 41 fixedly mounted on both sides of the bottom end of the base 1, and universal wheels 420 are symmetrically and vertically movably connected on both sides of the bottom end of the mounting frames 41. A bottom plate 42 is fixedly mounted between the two mounting frames 41, and a flip plate 43 is movably connected to one side of the bottom end of the bottom plate 42. A rotating plate 45 is movably connected to the middle part of one end of the flip plate 43 through a cylinder, and a support rod 46 is connected to the bottom of the rotating plate 45. The support rod 46 is laterally movably connected to the top of the bottom plate 42, and a protrusion 44 is movably connected to the top of the flip plate 43. The protrusion 44 is slidably connected to the inside of the base 1. A positioning block 421 is fixedly mounted at the top of the bottom plate 42 corresponding to one side of the flip plate 43, and a damper 422 is fixedly mounted on the top of the positioning block 421.

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, circles 415 are fixedly installed on both sides of the outer surface of the support rod 46, and a fixing column 47 is sleeved inside the circle 415. Positioning plates 48 are symmetrically welded at both ends of the fixing column 47. The positioning plates 48 are fixedly installed on the top of the bottom plate 42, and the same clamping plate 49 is fixedly installed between the tops of the two positioning plates 48;

[0039] By using the positioning plate 48, the fixing column 47 can be fixed, which changes the difficulty of fixing the fixing column 47. The fixing column 47 is used to limit the circle 415 to prevent the circle 415 from being offset. At the same time, under the action of the clamping plate 49, it is used to clamp and fix the cable.

[0040] like Figure 3 , Figure 4 and Figure 5 As shown, a rectangular block is welded on the top edge of the clamping plate 49, a magnetic plate 412 is equidistantly slidably connected to the top of the clamping plate 49, moving blocks 411 are symmetrically fixedly installed on both sides of the magnetic plate 412, and the moving blocks 411 are slidably connected to the inside of the clamping plate 49, and vertical bars 410 are fixedly installed at positions on both sides of the clamping plate 49 corresponding to one side of the moving blocks 411, and an iron plate 413 is slidably installed at the top of the clamping plate 49 at a position on one side of the magnetic plate 412, and a guide plate 414 is fixedly installed on one side edge of the iron plate 413, one end of the guide plate 414 is fixedly connected to the outside of the circle 415, and a roller 416 is rotatably connected to the inside of the guide plate 414, and the outside of the roller 416 and the inner wall of the bottom plate 42 fit each other;

[0041] When the support rod 46 moves, it drives the circle 415 to move, and when the circle 415 moves, it drives the guide plate 414 to move. When the guide plate 414 moves, it drives the roller 416 to move inside the bottom plate 42, so that the movement of the guide plate 414 is more stable, and when the guide plate 414 moves, it drives the iron plate 413 to move. When the iron plate 413 moves, it is adsorbed by a magnetic plate 412, and at this time drives a magnetic plate 412 to move. When one magnetic plate 412 and another magnetic plate 412 are attached, when the iron plate 413 moves, it drives the two magnetic plates 412 to move synchronously, and moves in sequence, so that the three magnetic plates 412 and the iron plate 413 form an overall movement, which changes the difficulty of movement between multiple pieces.

[0042] When the iron plate 413 moves, it drives the magnetic plate 412 to move, and when the magnetic plate 412 moves, it drives the moving block 411 to move, so that the moving block 411 contacts with multiple vertical bars 410 one by one in sequence, so that the multiple magnetic plates 412 are placed separately, and then the cables at the top of the clamping plate 49 are clamped and fixed in sequence.

[0043] like Figure 3 , Figure 4 and Figure 5 As shown, a threaded rod 419 is connected to the inside of the mounting frame 41 through a thread, and the bottom end of the threaded rod 419 is movably connected to the top end of the universal wheel 420. A screw rod 417 is connected to the inside of the support rod 46 through a thread, and the screw rod 417 is rotatably connected to the top end of the bottom plate 42. One end of the screw rod 417 is connected to the output shaft of a reducer 418, and the reducer 418 is fixedly installed at the bottom end of the bottom plate 42.

[0044] The operation of the reducer 418 drives the threaded rod 419 to rotate, and the rotation of the threaded rod 419 drives the support rod 46 to move. When the support rod 46 moves, the rotating plate 45 is driven to deflect, thereby changing the deflection difficulty of the rotating plate 45;

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, the length of the vertical bar 410 is successively reduced from the reducer 418 toward the damper 422, the height between the lowest point of the vertical bar 410 and the ground is successively reduced from the reducer 418 toward the damper 422, the length of the moving block 411 is successively increased from the reducer 418 toward the damper 422, the moving block 411 is successively reduced from the reducer 418 toward the highest point in the damper 422, and the magnetic poles of two adjacent magnetic plates 412 are opposite;

[0046] When the iron plate 413 moves, it drives the magnetic plate 412 to move, and when the magnetic plate 412 moves, it drives the moving block 411 to move, so that the moving block 411 contacts with multiple vertical bars 410 one by one in sequence, so that the multiple magnetic plates 412 are placed separately, and then the cables at the top of the clamping plate 49 are clamped and fixed in sequence.

[0047] like Figure 3 and Figure 6 As shown, a connecting assembly 5 is installed inside the movable frame 3, and the connecting assembly 5 includes a horizontal bar 51 fixedly installed inside the movable frame 3, a plurality of piston rods 52 are installed at one end of the horizontal bar 51, a plurality of round tubes 53 are sleeved on the outside of the plurality of piston rods 52, a same mounting plate 54 is installed between the outsides of the plurality of round tubes 53, a suction cup 55 is installed between one end of the plurality of round tubes 53, and a plurality of electric telescopic rods 511 are installed between the opposite surfaces of the horizontal bar 51 and the mounting plate 54;

[0048] When the electric telescopic rod 511 is connected to a power source and starts to operate, the operation of the electric telescopic rod 511 drives the mounting plate 54 to move, and the movement of the mounting plate 54 drives the multiple round tubes 53 to move outside the piston rod 52. At this time, the round tube 53 makes the suction cup 55 and the CT device fit together, and under the action of the piston rod 52, the suction cup 55 and the CT device are fit and fixed, so that the scanning bed and the CT device are positioned to prevent the scanning bed from shaking.

[0049] like Figure 3 and Figure 6 As shown, a connecting rope 56 is symmetrically installed on the top of the mounting plate 54, one end of the connecting rope 56 is connected to a baffle 510, the distance between the baffle 510 and the suction cup 55 is greater than the height of the baffle 510, a positioning sleeve 57 is sleeved on the outer side of the connecting rope 56, an extrusion strip 58 is fixedly installed on one end of the positioning sleeve 57, a spring rod 59 is embedded and installed at a single point on one end of the extrusion strip 58, and the spring rod 59 is fixedly installed inside the connecting frame 2;

[0050] As the mounting plate 54 moves, it drives the connecting rope 56 to move, and as the connecting rope 56 moves, it drives the baffle 510 to rise. When the baffle 510 completely enters the interior of the connecting frame 2, the mounting plate 54 continues to move. At this time, the connecting rope 56 applies pressure to the positioning sleeve 57, causing the positioning sleeve 57 to move. When the positioning sleeve 57 moves, it drives the extrusion bar 58 to move. When the extrusion bar 58 moves, it drives the spring rod 59 to be compressed. This method can facilitate the lifting and lowering of the baffle 510, and can facilitate the resetting of the baffle 510, thereby changing the difficulty of lifting and lowering and resetting the baffle 510.

[0051] A method for using a movable scanning bed of a medical CT device comprises the following steps:

[0052] Step 1: Material transfer: Pack the scanning bed in a wooden box and transport it to the predetermined location. When unloading, overlap the partitions on the top of the wooden box along the edge of the wooden box and the ground to form a temporary operating platform;

[0053] Step 2: Height adjustment: Use the lifting assembly 4 of the scanning bed to adjust the height of the scanning bed and the ground so that it can move along the top of the wooden box;

[0054] Step 3: Personnel use: The patient lies flat or prone on the top of the movable frame 3;

[0055] Step 4: Connect and fix: fix the scanning bed and the CT device by connecting the component 5;

[0056] Step 5: Height adjustment: Continue to use the lifting assembly 4 to adjust the height of the movable frame 3 so that the bottom end of the movable frame 3 is flush with the internal access area of ​​the CT device;

[0057] Step 6: Detection: Push the movable frame 3 to enter the interior of the device. At this time, the CT device will perform internal detection to confirm the correct posture of the personnel and determine whether the usage steps are correct based on the detection results. If correct, the next step will be performed.

[0058] Working principle: During the actual use of the device, the personnel rotate the threaded rod 419, and the threaded rod 419 drives the universal wheel 420 to move, so that the height between the mounting frame 41 and the base plate 42 and the ground is adjusted. Then the personnel pushes the scanning bed assembled between the base 1, the connecting frame 2 and the movable frame 3, and then the patient lies flat on the top of the movable frame 3. At this time, the scanning bed continues to be pushed so that the scanning bed enters the side of the CT equipment, and then the electric telescopic rod 511 is started. The electric telescopic rod 511 is connected to the power supply and starts to run. As the electric telescopic rod 511 runs, it drives the mounting plate 54 to move. As the mounting plate 54 moves, it drives the connecting rope 56 to move. When the connecting rope 56 moves, it drives the baffle 510 to rise. When the baffle 510 does not rise, it can protect the outside of the suction cup 55 when not in use to prevent external dust from entering the outside of the suction cup 55, ensuring the cleanliness of the outside of the suction cup 55. When the baffle 510 is completely entered When the mounting plate 54 is inside the connection frame 2, the connecting rope 56 applies pressure to the positioning sleeve 57, so that the positioning sleeve 57 moves. When the positioning sleeve 57 moves, it drives the extrusion bar 58 to move. When the extrusion bar 58 moves, it drives the spring rod 59 to be compressed. In this process, when the mounting plate 54 moves, it synchronously drives the multiple round tubes 53 to move outside the piston rod 52. At this time, the round tube 53 makes the suction cup 55 and the CT device fit together. Under the action of the piston rod 52, the residual gas inside the suction cup 55 and the CT device after fitting together is adsorbed, so that the suction cup 55 and the CT device fit together and are fixed, effectively preventing the movement of the patient and the device during the scanning process, thereby ensuring the stability of the scanning and the image quality, and the residual gas between the suction cup 55 and the CT device is adsorbed to ensure that the two are perfectly sealed and bonded, avoiding the phenomenon of unstable connection between the suction cup 55 and the CT device due to residual gas;

[0059] Then, the reducer 418 is started. When the reducer 418 is running, it drives the screw rod 417 to rotate. When the screw rod 417 rotates, it drives the support rod 46 to move. When the support rod 46 moves, it drives the circle 415 to move. When the circle 415 moves, it drives the guide plate 414 to move. When the guide plate 414 moves, it drives the roller 416 to move inside the bottom plate 42, so that the movement of the guide plate 414 is more stable, and when the guide plate 414 moves, it drives the iron plate 413 to move. When the iron plate 413 moves, it is attracted to a magnetic plate 412, and then drives a magnetic plate 412 to move. When a magnetic plate 412 and another magnetic plate 412 are attracted to each other, When one magnetic suction plate 412 is fitted, the iron plate 413 moves and simultaneously drives the two magnetic suction plates 412 to move, and they move in sequence, so that the three magnetic suction plates 412 and the iron plate 413 form an integral movement, which changes the difficulty of movement between the multiple magnetic suction plates 412 and the iron plate 413. At this time, the multiple magnetic suction plates 412 and the iron plate 413 cannot block the cables at the top of the clamping plate 49, so that the cables can change their angles. On the contrary, the cables can be clamped inside the clamping plate 49, preventing the cables clamped inside the clamping plate 49 from being pressed together due to disorder, further protecting the cables and increasing the service life of the cables.

[0060] At the same time, as the support rod 46 moves, the bottom end of the rotating plate 45 is driven to move, causing the rotating plate 45 to deflect. When the rotating plate 45 deflects, it drives the flip plate 43 through the cylinder. When the flip plate 43 deflects, it drives the protrusion 44 to move inside the bottom plate 42. At this time, the flip plate 43 and the rotating plate 45 rotate crosswise and synchronously, and drive the bottom plate 42 to rise. When the bottom plate 42 rises, the base 1, the connecting frame 2 and the movable frame 3 are driven to rise and fall. When the movable frame 3 moves to a predetermined position, the movable frame 3 is pushed to move, so that it enters the inside of the CT equipment, and then the patient is tested. However, by positioning the support rod 46 up and down and front and back, the support rod 46 can be smoothly displaced left and right along the horizontal plane, and then the rotating plate 45 can be smoothly rotated, so that the movable bed can rise more smoothly, thereby improving the accuracy of the movable bed's rise. The structure is simple and easy to use, and can also stably clamp and place the connected cables to prevent the cables from being clamped and causing the movable bed to be clamped during the rising process. Under the action of the damper 422, the impact force of the movable bed during recovery is reduced, further improving the stability during recovery.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
