Description

Technical Field

[0001] This invention specifically relates to a CT image reading device. Background Technology

[0002] CT scans, as the core medical carriers of tomographic images of the human body, play an irreplaceable role. They are typically based on a high-strength polyester film coated with a silver halide photosensitive coating. After exposure and development, they form grayscale images containing tomographic structures of human organs and tissues. Doctors need to observe and analyze CT scans using image reading devices.

[0003] For example, Chinese invention patent with publication number CN113031285B provides an adjustable CT film reading device. The size of the two CT film fixing mechanisms inside the device can be adjusted, which is convenient for clamping and fixing CT films of different sizes. It is also beneficial for fixing CT films that have been magnified to a certain extent onto the CT film fixing mechanism when multiple doctors are studying CT films.

[0004] However, existing CT scan reading devices mostly consist of a reading frame and a simple fixing structure. During use, medical staff must manually place the CT scans into the reading frame and secure them using clips and other components. Because CT scans are relatively soft and have a fixed size, repeated adjustments are often required during installation. Furthermore, to prevent wrinkles from affecting observation, the edges of the scans must be manually pulled to ensure flatness. The entire installation process is cumbersome and time-consuming. Especially in scenarios with many patients and requiring continuous scan reading, the cumbersome installation steps significantly extend the preparation time for each scan, reduce overall reading efficiency, increase the workload of medical staff, and hinder rapid diagnostic work. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention proposes a CT video reading device to solve the technical problem mentioned in the background art that most existing CT video reading devices require a cumbersome installation process to install the video, and the video needs to be stretched during the installation process to achieve the best viewing effect, resulting in a long overall time requirement and reduced reading efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a CT image reading device, comprising: The film reader is equipped with a mounting frame, and the mounting frame has an inverted trapezoidal first placement opening and a second placement opening at both ends; The conveying mechanism is provided in two sets, which are respectively located on both sides of the mounting frame to convey the placed film; The mounting brackets are arranged in four sets, two pairs opposite each other at both ends of the mounting frame. The mounting brackets are connected to the conveying mechanism via a drive mechanism, which intermittently converts the power of the conveying mechanism into the sliding of the two sets of mounting brackets. Multiple sets of clamping blocks are provided, and they are located at the four corners of the mounting frame in pairs. The clamping blocks are connected to the mounting frame through a linkage mechanism. The linkage mechanism converts the movement of the mounting frame into driving the clamping blocks to close and slide in a direction away from the center of the mounting frame.

[0007] In a preferred embodiment, a support frame is provided at the bottom of the film reader, one end of which is arc-shaped and connected to the bottom surface of the film reader, and the second placement opening is located above the arc-shaped end of the support frame.

[0008] In a preferred embodiment, the conveying mechanism includes: Two sets of synchronous pulleys are arranged at intervals, and each set can be rotated on the mounting frame; A timing belt is fitted onto the two sets of timing pulleys, and flexible racks are provided on both sides of the belt. Multiple sets of conveyor wheels are provided, rotatably mounted in pairs on the mounting frame. The edges of each adjacent pair of conveyor wheels are made of flexible material and abut against each other. Each conveyor wheel is equipped with a gear that meshes with a flexible rack. A power unit, mounted on the mounting frame, is provided to drive the gear to rotate.

[0009] In a preferred embodiment, the power assembly includes: A drive motor is mounted on the mounting frame, and its output shaft is connected to one of the sets of conveyor wheels; and The connecting rod is fixedly connected at both ends to a corresponding set of conveyor wheels on both sides of the mounting frame.

[0010] In a preferred embodiment, the drive mechanism includes: A drive column is disposed on the side of the synchronous belt. An inclined groove is formed on one side of the mounting bracket, and both ends of the inclined groove are connected to straight grooves. The drive column can slide into a set of straight grooves at the bottom. Two sets of drive blocks are provided, located at opposite ends of the mounting frame. The mounting frame has mounting slots, and the drive blocks are slidably engaged within these slots. An elastic element is disposed on the drive block and abuts against the inner wall of the mounting groove.

[0011] In a preferred embodiment, the linkage mechanism includes: A sliding frame is slidably fitted onto the drive block; A first linkage component is disposed on the slide frame and connected to the mounting frame to convert the movement of the drive block into driving the slide frame to slide along a through direction perpendicular to the mounting groove; The mounting base has a slider at one end, and a through groove is provided on one side of the sliding frame. The slider is slidably engaged in the through groove, and the clamping block is disposed on the mounting base; and A second linkage component is disposed on the slider and connected to the mounting frame to convert the movement of the sliding frame into driving the slider to slide in a direction toward the outside of the mounting frame.

[0012] In a preferred embodiment, the first linkage component includes: A first guide rod is disposed on the slide frame; and The first inclined frame is disposed within the mounting groove, and the first guide rod is slidably engaged within the first inclined frame.

[0013] In a preferred embodiment, the second linkage component includes: A second guide rod is disposed on the slider; and The second inclined frame is disposed on the side wall of the mounting frame, and the second guide rod is slidably engaged on the second inclined frame.

[0014] In a preferred embodiment, a flexible ring is provided inside the mounting base, and a mounting rod is provided at the end of the clamping block, with the mounting rod passing through the flexible ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When in use, the CT scan is placed into the mounting frame through the first placement port at the top. By setting up two sets of conveying mechanisms, the placed CT scan can be automatically transported, eliminating the tedious steps of manual installation. The drive mechanism intermittently converts the power of the conveying mechanism into the sliding power of the mounting frame. The linkage mechanism then drives the clamping block to close and slide away from the center of the mounting frame. During the transport process, the automatic positioning and pulling of the scan is achieved intermittently. The scan can be quickly brought to the best viewing state without manual operation, which greatly shortens the time for installing and adjusting the scan, reduces the workload of medical staff, and significantly improves the efficiency of scan reading. It is especially suitable for scenarios that require rapid processing of multiple CT scans. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0020] Example: like Figure 1 , 2 As shown, the present invention provides a CT image viewing device, including a viewing frame 1, a mounting frame 2 on the viewing frame 1, and inverted trapezoidal first placement opening 3 and second placement opening 4 at both ends of the mounting frame 2. A support frame 5 is provided at the bottom of the viewing frame 1, one end of the support frame 5 is arc-shaped and connected to the bottom surface of the viewing frame 1, and the second placement opening 4 is located above the arc-shaped end of the support frame 5.

[0021] When in use, the film to be viewed can be placed into the mounting frame 2 through the first placement port 3. After viewing the film, the film can be removed from the second placement port 4 and laid flat on the support frame 5 by the guidance of the arc-shaped support frame 5, so as to facilitate the loading and unloading of the film.

[0022] like Figure 2 , 5 As shown in Figures 6 and 7, in this embodiment, conveying mechanisms are provided on both sides of the mounting frame 2 to transport the placed film. Each conveying mechanism includes two sets of spaced synchronous wheels 9, rotatably mounted on the mounting frame 2. A synchronous belt 10 is fitted onto each set of synchronous wheels 9, and flexible racks 11 are provided on both sides of the synchronous belt 10. The mechanism also includes multiple sets of conveyor wheels 13, rotatably mounted on the mounting frame 2 in pairs. The edges of each adjacent pair of conveyor wheels 13 are made of flexible material and abut against each other. A gear 14 is provided on each conveyor wheel 13, meshing with the flexible racks 11. A power assembly for driving the gears 14 to rotate is provided on the mounting frame 2. The power assembly includes a drive motor 16 mounted on the mounting frame 2. The output shaft of the drive motor 16 is connected to one of the conveyor wheels 13, and the two ends of a connecting rod 15 are fixedly connected to the corresponding set of conveyor wheels 13 on both sides of the mounting frame 2.

[0023] After the film is placed in, the bottom of the film contacts the topmost conveyor wheel 13. The drive motor 16 is started, and the drive motor 16 drives the connecting rod 15 to rotate, so that one of the conveyor wheels 13 on both sides of the mounting frame 2 rotates. This drives the synchronous belt 10 to move through the meshing of the gear 14 and the flexible rack 11. During the movement, the synchronous belt 10 can control the rotation of the other multiple sets of conveyor wheels 13 to transport the film into the mounting frame 2. Lights can be added inside the mounting frame 2 to facilitate film viewing.

[0024] like Figure 5 , 6 As shown in Figure 7, in this embodiment, two sets of oppositely arranged mounting frames 17 are provided at both ends of the mounting frame 2. The mounting frames 17 are connected to the conveying mechanism through a drive mechanism. The drive mechanism intermittently converts the power of the conveying mechanism into driving the two sets of mounting frames 17 to slide. The drive mechanism includes a drive column 12 provided on the side of the synchronous belt 10. An inclined groove 18 is provided on one side of the mounting frame 17. Both ends of the inclined groove 18 are connected to straight grooves 19. The drive column 12 can slide into the bottom set of straight grooves 19. Both ends of the mounting frame 17 are provided with drive blocks 20. The mounting frame 2 is provided with a mounting groove 6. The drive block 20 is slidably locked in the mounting groove 6. An elastic element 30 is provided between the drive block 20 and the inner wall of the mounting groove 6.

[0025] When the conveying mechanism transports the film, as the film is about to fully enter the mounting frame 2, the drive column 12 slides from bottom to top into a set of straight grooves 19 at the bottom. Through its cooperation with the inclined groove 18, it drives the mounting frame 17 to slide laterally as a whole, compressing the elastic element 30. After viewing the film, the conveying mechanism continues to move until the drive column 12 slides out of the set of straight grooves 19 at the top. Under the action of the elastic element 30, the mounting frame 17 can then be reset.

[0026] like Figure 3 , 4 As shown in Figures 8 and 9, in this embodiment, the mounting frame 2 is also provided with multiple sets of clamping blocks 29. The multiple sets of clamping blocks 29 are located at the four corners of the mounting frame 2 in pairs. The clamping blocks 29 are connected to the mounting bracket 17 through a linkage mechanism. The linkage mechanism converts the movement of the mounting bracket 17 into driving the clamping blocks 29 to close and slide in a direction away from the center of the mounting frame 2. The linkage mechanism includes a sliding frame 21 that is slidably sleeved on the driving block 20. The sliding frame 21 is provided with a first linkage component that is connected to the mounting frame 2. The first linkage component converts the movement of the driving block 20 into driving the sliding frame 21 to slide in a direction perpendicular to the through direction of the mounting groove 6. The first linkage component includes a first guide rod 22 provided on the sliding frame 21. A first inclined frame 7 is provided in the mounting groove 6. The first guide rod 22 is slidably locked in the first inclined frame 7. A slider 25 is provided at the end of the mounting base 24. A through groove 23 is opened on one side of the sliding frame 21. The slider 25 is slidably locked in the through groove 23. The clamping blocks 29 are provided on the mounting base 24.

[0027] During the lateral sliding process, the mounting bracket 17 drives the clamping block 29 to slide laterally, and through the cooperation of the first guide rod 22 and the first inclined frame 7, the sliding frame 21 is controlled to slide in the direction perpendicular to the through direction of the mounting groove 6, so that the two sets of clamping blocks 29 close together to clamp the film. At the same time, the mounting bracket 17 pulls the sliding frame 21 to slide laterally, so that the clamping block 29 slides laterally and applies a lateral pulling force to the film.

[0028] like Figure 3 , 4 As shown in Figures 8 and 9, in this embodiment, the linkage mechanism further includes a second linkage component disposed on the slider 25 and connected to the mounting frame 2. The second linkage component converts the movement of the sliding frame 21 into driving the slider 25 to slide in the direction toward the outside of the mounting frame 2. The second linkage component includes a second guide rod 26 disposed on the slider 25, and a second inclined frame 8 is disposed on the side wall of the mounting frame 2. The second guide rod 26 is slidably engaged with the second inclined frame 8.

[0029] During the horizontal sliding and closing process of the clamping block 29, the slider 25 is controlled to slide longitudinally in the through groove 23 through the cooperation of the second guide rod 26 and the second inclined frame 8, thereby driving the clamping block 29 to slide in the vertical direction. In conjunction with the first linkage component, the clamping block 29 can slide towards the four corners of the mounting frame 2 to pull the film, avoid the film from bending and wrinkling during the viewing process, and improve the viewing effect.

[0030] like Figure 8 As shown, in this embodiment, a flexible ring 27 is provided inside the mounting base 24, and a mounting rod 28 is provided at the end of the clamping block 29, with the mounting rod 28 passing through the flexible ring 27. The arrangement of the flexible ring 27 allows the pulling force applied to the film by the clamping block 29 to be buffered to a certain extent, avoiding excessive pulling force that could damage the film and improving the applicability of the device.

[0031] Specific usage and beneficial effects of the present invention: When in use, the CT film is placed into the mounting frame 2 through the first placement port 3 at the top. By setting up two sets of conveying mechanisms, the placed CT film can be automatically conveyed, eliminating the tedious steps of manual installation. The drive mechanism intermittently converts the power of the conveying mechanism into the sliding power of the mounting frame 17. The linkage mechanism then drives the clamping block 29 to close and slide away from the center of the mounting frame 2. During the conveying process, the automatic positioning and pulling of the film is achieved intermittently. The film can be quickly brought to the best viewing state without manual operation, which greatly shortens the time for installing and adjusting the film, reduces the workload of medical staff, and significantly improves the efficiency of film reading. It is especially suitable for scenarios that require rapid processing of multiple CT films.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above.
