Description

Technical Field

[0001] The present invention relates to the technical field of image film fixation, and particularly to a fixation device for radiological medical image films. Background Art

[0002] Medical imaging refers to the technology and processing process of obtaining internal tissue images of the human body or a part of the human body in a non-invasive manner for medical treatment or medical research. It includes the following two relatively independent research directions: medical imaging systems and medical image processing. The former refers to the process of image formation, including research on imaging mechanisms, imaging equipment, imaging system analysis, etc.; the latter refers to further processing of the obtained images, with the purpose of restoring originally unclear images, or highlighting certain feature information in the images, or performing pattern classification on the images, etc.

[0003] Chinese patent document CN213457549U discloses a fixation device for radiological medical image films, which includes a base and a light-transmitting screen fixedly connected to the base. A box body is slidably connected to the base. A first support plate and a second support plate are fixedly connected inside the box body. A first screw rod and a second screw rod are respectively rotatably connected to the first support plate and the second support plate; Clamping rod assemblies are threadedly connected to both the first screw rod and the second screw rod. The box body is also connected with a driving part for driving the first screw rod and the second screw rod to rotate. A fixed column is provided on the upper part of the base, and a tension spring is connected between the fixed column and the box body; By driving the first screw rod and the second screw rod to rotate simultaneously through the driving part, the two clamping rod assemblies flatten the middle part of the image film to both ends and stop when moving to the end of the image film, so as to squeeze out the air between the image film and the light-transmitting screen, and the image film can be fully attached to the light-transmitting screen for a good light-transmitting effect.

[0004] However, when this device is actually used, it requires medical staff to fix the image film, which is inconvenient for operating the device. In addition, the backlight board is prone to overheating after long-term use, shortening its service life. Summary of the Invention

[0005] The main purpose of the present invention is to provide a fixation device for radiological medical image films, which can effectively solve the problems of inconvenient operation and shortened service life.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0007] A radiological medical image fixing device, comprising a box body, a first support frame is fixed at the front end of the box body, a control panel is fixed at the lower end of the first support frame, two driving motors are symmetrically fixed on the bottom surface of the inner cavity of the first support frame, a screw rod is fixed at the output end of the driving motor, a scanner is jointly arranged on the outer surfaces of the two screw rods, a light-transmitting plate is fixed on the front side surface of the inner cavity of the box body, a backlight assembly is also fixed on the rear side surface of the inner cavity of the box body, and a dust removal assembly is also arranged at the lower end of the scanner.

[0008] Preferably, the light-transmitting plate is made of glass material, and a plurality of through holes are also formed on the surface of the light-transmitting plate.

[0009] Preferably, the diameter of the through hole is not greater than 1 mm, and the hole pitch of the through hole is greater than 2 mm.

[0010] Preferably, the backlight assembly includes a backlight plate fixed on the rear side of the inner cavity of the box body, a heat-conducting copper sheet is fixed at the rear end of the backlight plate, ventilation grooves are formed at both the left and right ends of the box body, heat dissipation fins are fixed on both the left and right sides of the inner cavity of the box body, and the heat-conducting copper sheet is connected to the heat dissipation fins. Heat dissipation fan groups are fixed at one ends of the two heat dissipation fins close to each other. When the heat dissipation fan groups work, air enters the inside of the box body from the through holes and is discharged through the ventilation grooves.

[0011] Preferably, two flow guide plates are symmetrically fixed on the bottom surface of the inner cavity of the box body, and the two flow guide plates are located at the front side.

[0012] Preferably, one sides of the two flow guide plates close to each other are inclined forward.

[0013] Preferably, the dust removal assembly includes an air suction fan fixed at the lower end of the box body and a plurality of second support frames. An air suction manifold is also fixed at the lower end of the scanner. An installation base is fixed at the output end of the air suction manifold. An air filter housing is threadedly installed on the outer surface of the installation base, and an air filter element adapted to the installation base is also arranged inside the air filter housing.

[0014] Preferably, the input end of the air suction fan is connected to the air suction manifold through a pipeline, and the middle part of the pipeline is a telescopic corrugated pipe.

[0015] Preferably, a plurality of ventilation holes are formed on the outer surface of the air filter housing.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This image film fixing device adopts the design of a backlight assembly. Through the cooperative design of a heat dissipation fan group and the through holes of the scanner, a uniform air flow adsorption force is formed when the image film is placed, ensuring that the image film is closely attached to the glass surface, thereby achieving the purpose of fixing the image film, facilitating the operation of the device. At the same time, by using the design of the deflector, the air flow is guided to spread to the central area of the light-transmitting plate, making the adsorption force distribution more uniform, effectively solving the problem of insufficient suction force in the central area of the traditional device, while reducing air flow disorder and energy loss, and improving the adsorption efficiency.

[0018] 2. This image film fixing device adopts a combined structure of a heat-conducting copper sheet and heat dissipation fins, quickly conducting the heat of the backlight board to the heat dissipation fins. With the design of two-way heat dissipation fins, an air circulation heat dissipation path penetrating the box body is formed, significantly reducing the working temperature of the backlight assembly and extending the service life of the device.

[0019] 3. This image film fixing device adopts the design of a dust removal assembly, which is a combination of an air suction manifold connected by a telescopic bellows and an air filter. In the non-working state, it can perform directional cleaning on the through holes of the light-transmitting plate. Through the filtration of the air filter, secondary dust pollution is avoided, maintaining the high light transmittance of the light-transmitting plate, ensuring the clarity of image observation. The dust removal assembly adopts a detachable air filter design with threaded connection, facilitating medical staff to quickly replace the air filter. And ventilation holes are opened on the surface of the air filter housing to achieve safe discharge of filtered air, ensuring the cleanliness and hygiene of the operating environment.

[0020] 4. This image film fixing device adopts the design of through holes, which can reduce the light shielding area and edge scattering effect. At the same time, due to the design of a smaller through hole diameter and stronger light on the light-transmitting plate, it can prevent medical staff from observing the through holes when observing the image film, minimizing the light shielding area to the greatest extent while ensuring air permeability and improving the image observation effect.

[0029] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0030] Embodiment 1

[0031] As Figure 1 - Figure 3 shown, a fixing device for radiological medical imaging films includes a box body 1. A first support frame 11 is fixed at the front end of the box body 1. A control panel 12 is fixed at the lower end of the first support frame 11. Two driving motors 13 are symmetrically fixed on the bottom surface of the inner cavity of the first support frame 11. A screw 14 is fixed at the output end of the driving motor 13. A scanner 15 is arranged on the outer surfaces of the two screws 14. When the two screws 14 rotate simultaneously, the scanner 15 can move up and down, so as to scan the film placed in front of the translucent plate 16 and transmit it to a computer for storage and viewing. A translucent plate 16 is fixed on the front side surface of the inner cavity of the box body 1. A backlight component 2 is also fixed on the rear side surface of the inner cavity of the box body 1. A dust removal component 4 is further arranged at the lower end of the scanner 15.

[0032] In addition, in order to improve the light transmittance of the translucent plate 16, the translucent plate 16 is made of glass material, which has higher stability compared with acrylic material (such as acrylic plates are prone to heat softening and gradually turning yellow, etc.). A plurality of through holes are also formed on the surface of the translucent plate 16. The through holes are used for ventilation. And to ensure the light transmittance of the translucent plate 16, the diameter of the through holes is not greater than 1 mm, and the hole pitch of the through holes is greater than 2 mm, which can reduce the light shielding area and edge scattering effect. At the same time, due to the design of the smaller diameter of the through holes and the stronger light of the translucent plate 16, it can prevent medical staff from observing the through holes when observing the imaging film, and improve the stability of the device.

[0033] As Figure 2 - Figure 4As shown in the figure, the backlight assembly 2 includes a backlight panel 21 fixed to the rear side of the inner cavity of the box body 1. The backlight panel 21 is a prior art. When the image film is placed on the front side of the light-transmitting plate 16, the light from the backlight panel 21 shines on the image film, facilitating the viewing of the image film. A heat-conducting copper sheet 22 is fixed to the rear end of the backlight panel 21. Ventilation grooves 23 are provided at both the left and right ends of the box body 1. The ventilation grooves 23 can let the air inside the box body 1 out. Heat-dissipating fins 24 are fixed to both the left and right sides of the inner cavity of the box body 1, and the heat-conducting copper sheet 22 is connected to the heat-dissipating fins 24. Since copper has good heat-conducting performance, the heat generated when the backlight panel 21 works can be transmitted to the heat-dissipating fins 24. Heat-dissipating fan groups 25 are fixed to the ends of the two heat-dissipating fins 24 that are close to each other. When the heat-dissipating fan groups 25 work, they can accelerate the air flow inside the heat-dissipating fins 24 and speed up heat dissipation. When the heat-dissipating fan groups 25 work, air enters the box body 1 from the through holes and is discharged through the ventilation grooves 23, thus completing the air circulation inside the box body 1. When an image film is placed on the front end of the light-transmitting plate 16, under the action of the rapid air flow, the image film can be adsorbed onto the surface of the light-transmitting plate 16, thus completing the fixation of the image film. At the same time, the air flow can take away the heat on the heat-dissipating fins 24, and due to the design of connecting the heat-conducting copper sheet 22 and the heat-dissipating fins 24, the heat dissipation of the backlight panel 21 is completed.

[0034] Further, to facilitate the adsorption of the image film on the front side of the light-transmitting plate 16, as Figure 2 and Figure 4 shown, two flow guide plates 3 are symmetrically fixed to the bottom surface of the inner cavity of the box body 1, and the two flow guide plates 3 are located at the front side. The sides of the two flow guide plates 3 that are close to each other are inclined forward. Due to the design of arranging the heat-dissipating fan groups 25 on both the left and right sides of the box body 1, when the heat-dissipating fan groups 25 are working, the original air flow is easily concentrated in the edge area, resulting in insufficient air flow in the middle of the light-transmitting plate 16. Therefore, the inclined design of the flow guide plates 3 is needed. The flow guide plates 3 change the direction of the air flow, guiding the air flow at the edge to spread towards the middle of the light-transmitting plate 16, enabling each area on the glass surface to obtain a more uniform air flow adsorption force, ensuring that the whole film fits tightly against the glass, avoiding situations such as warping and loose fitting in the middle area due to insufficient suction, and at the same time reducing air flow disorder and energy loss, making the suction generated by the fan act more efficiently on the glass surface, maximizing the utilization of air flow energy without replacing the fan and enhancing the adsorption effect.

[0035] The specific implementation of this embodiment is as follows: When the device is in use, first control the backlight panel 21 and the heat dissipation fan group 25 to work, and then place the video film to be viewed in front of the light-transmitting plate 16. Since the air enters the box body 1 from the through holes and is discharged from the ventilation slots 23 when the heat dissipation fan group 25 is working, under the action of the air flow, the video film can be adsorbed in front of the light-transmitting plate 16. At the same time, due to the design of the diversion plate 3, the direction of the air flow can be changed, guiding the air flow at the edge to diffuse towards the middle of the light-transmitting plate 16, so that each area of the glass surface can obtain a more uniform air flow adsorption force, ensuring that the whole film is closely attached to the glass;

[0036] When the backlight panel 21 is working, heat will be generated. If there is no heat dissipation for a long time, the brightness of the backlight panel 21 will be reduced. Due to the design of the heat-conducting copper sheet 22, the heat generated by the backlight panel 21 will be transmitted to the heat dissipation fins 24. When the heat dissipation fan group 25 is working, the flowing air can take away the heat of the heat dissipation fins 24, thus completing the heat dissipation of the backlight panel 21. The light of the backlight panel 21 shines on the video film, which is convenient for viewing the video film.

[0037] Embodiment Two

[0038] This embodiment is a further improvement of the dust removal component 4 on the basis of Embodiment One, so that medical staff can clean the through holes of the light-transmitting plate 16 when not viewing the video film, so as to improve the light transmittance of the light-transmitting plate 16.

[0039] As Figure 5 - Figure 7 shown, the dust removal component 4 includes an air suction fan 41 fixed to the lower end of the box body 1 and a plurality of second support frames 42. Among them, the second support frames 42 are used to fixedly install the mounting base 44 and the air filter housing 45. The lower end of the scanner 15 is also fixedly provided with an air suction manifold 43. One end of the air suction manifold 43 close to the light-transmitting plate 16 is provided with a plurality of holes, and the plurality of holes communicate with each other inside the air suction manifold 43. The input end of the air suction fan 41 is connected to the air suction manifold 43 through a pipeline, and the middle part of the pipeline is a telescopic corrugated pipe. The output end of the air suction manifold 43 is fixedly provided with a mounting base 44, and an air filter housing 45 is threadedly installed on the outer surface of the mounting base 44. An air filter element 46 adapted to the mounting base 44 is also provided inside the air filter housing 45. Among them, when the air suction fan 41 is working, the air enters from the air suction manifold 43 and then is discharged from the mounting base 44. When the air is discharged, it will first enter the air filter element 46 and then be discharged from the air filter housing 45, enabling the air filter element 46 to collect the sucked dust, preventing the dust from flying around when the device cleans the through holes of the light-transmitting plate 16, thus affecting the normal work of medical staff.

[0040] A plurality of ventilation holes are provided on the outer surface of the air filter housing 45, and the ventilation holes are used to discharge the filtered air.

[0041] The specific implementation manner of this embodiment is as follows: When the device cleans the dust and impurities inside the through holes of the light-transmitting plate 16, the suction fan 41 is first turned on. When the suction fan 41 works, through the mutual cooperation between the suction manifold 43 and the corrugated pipe, the dust and impurities in the through holes of the light-transmitting plate 16 are sucked into the suction manifold 43, and then the sucked dust is collected by the air filter element 46 to prevent the dust from flying around when the device cleans the through holes of the light-transmitting plate 16. The processed air is discharged through the ventilation holes.

[0042] It should be noted that the specific installation methods, circuit connection methods, and control methods of the control panel 12, the drive motor 13, the scanner 15, etc. in the present invention are all conventional designs, and the present invention will not elaborate in detail.

[0043] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
