Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a medical imaging film reading and fixing device. Background Art

[0002] In medical institutions, medical film is an important tool for medical imaging diagnosis, helping doctors accurately diagnose conditions and develop treatment plans. For example, X-ray film can be used for X-ray examinations of the chest, abdomen, bones, and other parts of the body to capture tissue images. CT film is used for computed tomography imaging, and MRI film is used for magnetic resonance imaging. Medical film records images using silver halide photosensitive materials, requiring specific light intensities and spectra to reproduce details. Therefore, it generally requires the use of a film reader for observation. However, most of the current film reading devices are single-group film reading structures with relatively simple functions. When diagnosing a disease, medical staff often need to refer to the image information of multiple films at the same time. However, the single-group film reading structure cannot meet this demand. Medical staff need to repeatedly change films for observation, which not only increases the operation steps but may also lead to information omissions. When multiple groups of film reading components are used in combination, they occupy a large space and are more troublesome to use. At the same time, when in use, most doctors need to manually fix the image film, which is prone to shifting, shaking, etc. during use, interfering with the medical staff's line of sight, greatly reducing the accuracy and reliability of film reading, and bringing potential risks to medical diagnosis.

An on / off switch for controlling the turning on of the illuminating lamps is fixedly connected to the viewing frame.

[0009] Furthermore, the drive assembly includes a servo motor, which is fixedly connected to the inner wall of the bottom of the reading frame. The output end of the servo motor is fixedly connected to a transmission rod via a coupling. The two ends of the transmission rod are respectively rotatably connected to the inner walls of the top and bottom of the reading frame. The transmission rod is fixedly connected to a drive gear, which meshes with a drive rack. The transmission rod is also fixedly connected with a first bevel gear, and the first bevel gear is connected to the film fixing assembly.

[0010] Furthermore, the film fixing assembly includes a second bevel gear, an end of the second bevel gear close to the first bevel gear is meshed with the first bevel gear, and an end of the second bevel gear away from the first bevel gear is fixedly connected to a synchronous gear via a connecting shaft, and a side of the synchronous gear away from the second bevel gear is rotatably connected to the inner wall of the reading frame via a connecting shaft, and a first synchronous rack and a second synchronous rack are further provided on both sides of the synchronous gear, and the first synchronous rack and the second synchronous rack are both meshed with the synchronous gear.

[0014] Compared with the prior art, the above solution has the following beneficial effects: 1. The operation process of the present invention is simple and easy to understand, and medical staff can easily get started. When placing the film, they only need to use the placement slots on the first reading frame and the second reading frame to quickly place the film in the appropriate position. After starting the servo motor, a series of actions are automatically completed. Under the coordinated action of components such as the driving gear and the driving rack, the second reading frame moves smoothly to the same level as the first reading frame, and the auxiliary roller slides along the slide groove.

[0015] 2. The present invention achieves film fixation through the negative pressure principle. When the servo motor drives the transmission rod to rotate, the synchronous gear pushes the first synchronous rack and the second synchronous rack towards each other, pulling the piston rod to slide in the piston cylinder to extract air, so that negative pressure is generated between the suction groove and the film. The film fits tightly on the light-transmitting plate, with an excellent fixing effect. During the film reading process, the film will not shift or shake, ensuring the accuracy and stability of observation, providing medical staff with clear and stable images, and helping to make accurate diagnoses.

[0016] 3. In the present invention, after use is completed, the servo motor is started again, and the driving gear will drive the driving rack to rotate in the opposite direction, so that the second viewing frame can automatically retract and reset, and at the same time drive the synchronous gear to reverse, so that the first synchronous rack and the second synchronous rack drive the piston rod to blow out the gas in the piston cylinder, so that the pressure between the film and the suction groove is restored, and the film automatically separates from the light-transmitting plate. At this time, medical staff can easily take out the film through the placement slot. The whole process does not require complicated operations and is convenient and fast.

[0017] 4. In the present invention, by cooperating with two sets of film reading components, doctors can observe and compare multiple films at the same time. Medical staff can understand the patient's condition more quickly and discover more potential problems by comparing the image information on different films, providing strong support for formulating more accurate treatment plans. At the same time, after use, the second film reading component can be folded back into the film reading rack, which greatly reduces the occupied area of ​​the device and avoids affecting the development of other medical work due to the equipment taking up too much space.

During use, a film is first placed in the first and second viewing frames 21 and 31 via the first placement slot 24 on the first viewing frame 21 and the second placement slot 39 on the second viewing frame 31, with the film positioned in front of the first and second light-transmitting plates 22 and 32. The drive assembly 4 is then activated, which drives the second viewing frame 31 out of the rear end of the first viewing frame 21 via the connecting assembly. When the second viewing frame 31 is level with the first viewing frame 21, the film fixing assembly 5 simultaneously secures the film. When reading films, first turn on the on / off switch 12 to turn on the lights in the first and second film reading frames 21 and 31. Medical staff can adjust the brightness of the lights through the knobs on the first and second film reading frames 21 and 31 as needed to make observation more accurate.

[0024] In this embodiment, the connecting assembly includes a plurality of synchronous links 35, and the plurality of synchronous links 35 are hinged to the adjacent connecting plates 33 through connecting shafts. The other ends of the plurality of synchronous links 35 are hinged to a synchronous frame 36 through the connecting shaft, and the plurality of synchronous links 35 are connected through the synchronous frame 36. A drive rack 37 is fixedly connected to the synchronous frame 36, and the drive rack 37 is connected to the drive assembly 4. The drive assembly 4 includes a servo motor 41, which is fixedly connected to the inner wall of the bottom of the reading frame 1. The output end of the servo motor 41 is fixedly connected to the transmission rod 42 through a coupling. The two ends of the transmission rod 42 are rotatably connected to the inner walls of the top and bottom of the reading frame 1, and the transmission rod 42 is fixedly connected to a driving gear 43, which meshes with the driving rack 37. The transmission rod 42 is also fixedly connected to a first bevel gear 44, which is connected to the film fixing assembly 5.

Slide grooves 11 are opened on the inner walls of the top and bottom of the reading frame 1, and multiple auxiliary rollers 38 are respectively slidably connected to adjacent slide grooves 11; When in use, the servo motor 41 is first started. The servo motor 41 drives the transmission rod 42 to rotate through the coupling. The driving gear 43 on the transmission rod 42 rotates synchronously. The driving gear 43 drives the driving rack 37 to move. The driving rack 37 simultaneously drives the synchronization frame 36 to move. The synchronization frame 36 drives the second reading frame 31 to move through multiple synchronization links 35. The two auxiliary rollers 38 slide outward along the slide groove 11 in the reading frame 1 at the same time. When the two auxiliary rollers 38 slide to the end of the slide groove 11, the driving rack 37 continues to push the synchronization frame 36 and the second reading frame 31 to move. At this time, the two auxiliary rollers 38 move toward the front end of the reading frame 1 under the guidance of the inclined surface of the slide groove 11, so that the second reading frame 31 is level with the first reading frame 21. When the film review is completed, the servo motor 41 is restarted to cause the drive gear 43 to drive the drive rack 37 to rotate in the opposite direction. When the drive rack 37 moves in the opposite direction, the synchronization frame 36 first pulls the multiple synchronization links 35 to rotate. The multiple synchronization links 35 pull the two auxiliary rollers 38 to slide along the slide groove 11, so that the second film review frame 31 returns to the rear end of the first film review frame 21 and is no longer horizontal with the first film review frame 21. The drive rack 37 continues to move and drives the multiple auxiliary rollers 38 to slide inward along the slide groove 11, so that the second film review frame 31 is reset. When the second film viewing frame 31 is reset, the film fixing assembly 5 releases the fixation of the film, and the film can be taken out from the first placement slot 24 and the second placement slot 39 .

[0025] In this embodiment, the film fixing assembly 5 includes a second bevel gear 51, and one end of the second bevel gear 51 close to the first bevel gear 44 is meshed with the first bevel gear 44, and the end of the second bevel gear 51 away from the first bevel gear 44 is fixedly connected to a synchronous gear 52 through a connecting shaft, and the side of the synchronous gear 52 away from the second bevel gear 51 is rotatably connected to the inner wall of the film reading frame 1 through a connecting shaft, and a first synchronous rack 53 and a second synchronous rack 54 are further provided on both sides of the synchronous gear 52, and the first synchronous rack 53 and the second synchronous rack 54 are both meshed with the synchronous gear 52, and a first piston cylinder 55 is provided directly below the first synchronous rack 53, and the first piston cylinder 55 is fixedly connected to the inner wall of the film reading frame 1, and a first piston rod is slidably connected in the first piston cylinder 55, and the first The top of the piston rod is fixed to the bottom of the first synchronous rack 53, and the bottom of the first piston cylinder 55 is connected to a first connecting pipe 57.

The extended end of the second connecting pipe 58 is connected to the two groups of second suction grooves 34 through the second reading frame 31.

[0026] When in use, when the servo motor 41 starts to drive the transmission rod 42 to rotate, the transmission rod 42 simultaneously drives the first bevel gear 44 to rotate, and the second bevel gear 51 meshing with the first bevel gear 44 rotates at the same time, and the second bevel gear 51 drives the synchronous gear 52 to rotate synchronously. When the synchronous gear 52 rotates, the first synchronous rack 53 and the second synchronous rack 54 provided on both sides of the synchronous gear 52 move towards each other under the push of the synchronous gear 52. When the first synchronous rack 53 and the second synchronous rack 54 move, they simultaneously pull the first piston rod and the second piston rod, so that the first piston rod and the second piston rod slide in the first piston cylinder 55 and the second piston cylinder 56 to exhaust air. The first piston cylinder 55 and the second piston cylinder 56 are respectively exhausted through the first connecting pipe 57 and the second connecting pipe 58, so that negative pressure is generated between the first suction groove 23 and the second suction groove 34 and the adjacent films, so that the films are respectively fitted with the first light-transmitting plate 22 and the second light-transmitting plate 32, and the films are fixed under the action of the negative pressure. When use is completed, when the second viewing frame 31 is reset, the second bevel gear 51 is reversed under the drive of the first bevel gear 44, causing the synchronous gear 52 to reverse. When the synchronous gear 52 reverses, it drives the first synchronous rack 53 and the second synchronous rack 54 to move in the direction away from each other, and pushes the first piston rod and the second piston rod to slide in the first piston cylinder 55 and the second piston cylinder 56. The gas in the first piston cylinder 55 and the second piston cylinder 56 is blown out through the first connecting pipe 57 and the second connecting pipe 58 by the push of the first piston rod and the second piston rod, so that the pressure between the film and the first suction groove 23 and the second suction groove 34 is restored, and the film is separated from the first light-transmitting plate 22 and the second light-transmitting plate 32. When the second viewing frame 31 is completely reset, the film can be taken out through the first placement groove 24 and the second placement groove 39.

[0027] The working principle of the present invention is: When in use, first place the film in the first viewing frame 21 and the second viewing frame 31 through the first placement slot 24 on the first viewing frame 21 and the second placement slot 39 on the second viewing frame 31, and place the film in front of the first light-transmitting plate 22 and the second light-transmitting plate 32; The servo motor 41 is started, and the servo motor 41 drives the transmission rod 42 to rotate through the coupling. The driving gear 43 on the transmission rod 42 rotates synchronously, and the driving gear 43 drives the driving rack 37 to move. The driving rack 37 also drives the synchronization frame 36 to move. The synchronization frame 36 drives the second film reading frame 31 to move through multiple synchronization links 35. The two auxiliary rollers 38 simultaneously slide outward along the slide 11 in the film reading frame 1. When the two auxiliary rollers 38 slide to the end of the slide 11, the driving rack 37 continues to push the synchronization frame 36 and the second film reading frame 31 to move. At this time, the two auxiliary rollers 38 move toward the front end of the film reading frame 1 under the guidance of the inclined surface of the slide 11, so that the second film reading frame 31 is level with the first film reading frame 21. When the servo motor 41 starts and drives the transmission rod 42 to rotate, the transmission rod 42 simultaneously drives the first bevel gear 44 to rotate, and the first bevel gear 44 drives the second bevel gear 51 and the synchronous gear 52 to rotate synchronously. When the synchronous gear 52 rotates, the first synchronous rack 53 and the second synchronous rack 54 provided on both sides of the synchronous gear 52 move towards each other under the push of the synchronous gear 52. When the first synchronous rack 53 and the second synchronous rack 54 move, they simultaneously pull the first piston rod and the second piston rod, so that the first piston rod and the second piston rod slide in the first piston cylinder 55 and the second piston cylinder 56 to exhaust air. The first piston cylinder 55 and the second piston cylinder 56 are respectively exhausted through the first connecting pipe 57 and the second connecting pipe 58, so that negative pressure is generated between the first suction groove 23 and the second suction groove 34 and the adjacent films, so that the films are respectively fitted with the first light-transmitting plate 22 and the second light-transmitting plate 32. Under the action of the negative pressure, the films are fixed; Turn on the on / off switch 12 to turn on the lights in the first and second viewing frames 21 and 31. Medical staff can adjust the brightness of the lights using the knobs on the first and second viewing frames 21 and 31 as needed to make observation more accurate. When the film review is completed, the servo motor 41 is restarted to cause the drive gear 43 to drive the drive rack 37 to rotate in the opposite direction. When the drive rack 37 moves in the opposite direction, the synchronization frame 36 first pulls the multiple synchronization links 35 to rotate. The multiple synchronization links 35 pull the two auxiliary rollers 38 to slide along the slide groove 11, so that the second film review frame 31 returns to the rear end of the first film review frame 21 and is no longer horizontal with the first film review frame 21. The drive rack 37 continues to move and drives the multiple auxiliary rollers 38 to slide inward along the slide groove 11, so that the second film review frame 31 is reset. When use is completed, when the second viewing frame 31 is reset, the second bevel gear 51 is reversed under the drive of the first bevel gear 44, causing the synchronous gear 52 to reverse. When the synchronous gear 52 reverses, it drives the first synchronous rack 53 and the second synchronous rack 54 to move away from each other, and pushes the first piston rod and the second piston rod to blow out the gas in the first piston cylinder 55 and the second piston cylinder 56 through the first connecting pipe 57 and the second connecting pipe 58, so that the pressure between the film and the first suction groove 23 and the second suction groove 34 is restored, and the film is separated from the first light-transmitting plate 22 and the second light-transmitting plate 32. When the second viewing frame 31 is completely reset, the film can be taken out through the first placement groove 24 and the second placement groove 39.
