Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable universal medical image reading device. Background Technology

[0002] As a standard professional lighting device in hospital radiology departments, film viewing lights are primarily used to view various medical imaging films such as X-ray films, CT scans, and MRI films. They are an important auxiliary tool for clinicians to diagnose diseases. These devices are based on a high-brightness, uniformly luminous panel, and the light source mostly uses LEDs. The light is soft and the brightness remains stable, which can clearly show the details of lesions and the texture of human tissue on the film, and can effectively avoid the problem of uneven light and shadow.

[0003] A Chinese utility model patent with publication number CN209946539U discloses a plug-and-play film reading light. This device, through the coordinated design of components such as a power cord, wires, lamp holder, and light-transmitting plate, facilitates film reading, allowing medical personnel to clearly and accurately view CT images. However, lung CT scans use tomographic imaging; the CT equipment scans lung tissue layer by layer with X-rays, generating independent images for each scan. These images are arranged in a multi-grid format on the film according to the scanning sequence. Therefore, using this type of film reading light to view lung CT scans presents challenges. When using film, each cell corresponds to only a local area of ​​a thin layer of the lung. The visible range of the image is narrow, and the proportion of the lesion displayed in a single cell is also extremely small. Those subtle inflammatory infiltration areas or detailed features of the lesion edge are easily obscured by this limited small image. Especially when medical staff explain the condition to patients, they cannot intuitively mark the specific location of the lesion for the patient during the review of the film, making it difficult for the patient to understand the location of the lesion. It also affects the doctor's detailed observation and judgment of the lesion details to a certain extent. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable universal medical image reading device. The magnifying lens installed on the front of the lamp cabinet can be adjusted in multiple directions through the first and second slides, and can be aligned with the target image area on the film. This facilitates doctors to observe and judge the details of lesions in detail, and can also clearly point out and explain the location of lesions to patients, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable universal medical image reading device includes a lamp cabinet. A light-transmitting panel is fixedly connected to the front end face of the lamp cabinet. Multiple power buttons are fixedly connected to the lamp cabinet below the light-transmitting panel. The power buttons are electrically connected to a main controller inside the lamp cabinet via wires. Guide rails are fixedly connected to the top and bottom of the lamp cabinet. An image magnification mechanism is provided between the two guide rails. The image magnification mechanism includes a first slide movably connected to the guide rails. A sub-plate is fixedly connected to the first slide. Two guide shafts are fixedly connected between the two sub-plates. A second slide is movably connected between the two guide shafts. Two positioning blocks are symmetrically movably connected to the rear side of the second slide. A mounting sleeve is fixedly connected to the front side of the second slide. An operating handle is inserted into the mounting sleeve and the second slide. The rear side of the operating handle extends between the two positioning blocks and is fixedly connected to a trapezoidal block. A magnifying glass is movably connected to one side of the second slide.

[0007] Preferably, the bottom of the first slide is rotatably connected to a plurality of first guide wheels, and the first slide is slidably connected to the guide rail via the plurality of first guide wheels. The first guide wheels are rubber wheels. When the two first slides are moved synchronously by the second slide, the two guide shafts and the sub-plate, the first slides can slide on the corresponding guide rail with the help of the bottom first guide wheels. The first guide wheels are rubber wheels, which can provide a certain damping for the movement of the first slides and facilitate the adjustment and positioning of the first slides.

[0008] Preferably, a plurality of second guide wheels are rotatably connected to the rear side of the second slide. The second slide is slidably connected between two guide shafts via the plurality of second guide wheels. Thus, the second slide moves in the Y direction between the two guide shafts with the help of the plurality of second guide wheels, while the guide shafts can move in the X direction in front of the lamp cabinet with the help of the sub-plate and the first slide, thereby facilitating quick adjustment of the setting position of the magnifying glass.

[0009] Preferably, a rotating groove is provided on the front side of the second slide with the mounting sleeve as the center, and a support block is fixedly connected to the second slide located below the rotating groove. The support block can limit the rotation of the mounting plate, so that the magnifying glass can be rotated around the fixed ring as the axis. Several limiting screws are also threadedly connected to the rear side of the second slide.

[0010] Preferably, the front threaded connection of the mounting sleeve has a limit cap, which facilitates the assembly of the operating handle with the second slide and the mounting sleeve. At the same time, the limit cap provides a base point for the operator's hand when the operating handle is pressed, making it easier to push and pull the second slide up and down through the mounting sleeve.

[0011] Preferably, the positioning block has two linear grooves, and each of the two positioning blocks has a slope and a T-shaped groove on its opposite side. The linear grooves are slidably connected to one of the limiting screws, so that the positioning block can slide horizontally on the two limiting screws by means of the two internal linear grooves under the push and pull operation of the trapezoidal block. The positioning block has an arc-shaped rubber pad on the side opposite to the guide shaft to increase the friction with the guide shaft, thereby realizing the positioning of the second slide table at any position between the two guide shafts.

[0012] Preferably, both sides of the trapezoidal block are provided with slopes and T-shaped sliders are fixedly connected thereto. The side of the operating handle away from the trapezoidal block is fixedly connected to a limiting ring. The T-shaped slider is slidably connected to one of the T-shaped grooves. The limiting ring is inserted into the mounting sleeve through the operating handle. The operating handle located between the limiting ring and the second slide is also fitted with a spring. With the help of the spring's pushing force on the limiting ring, the limiting ring can provide a continuous pulling force to the trapezoidal block towards the second slide through the operating handle. This allows the trapezoidal block to use the slopes on both sides corresponding to one side of the positioning block to press and abut against the outside of the guide shaft on the side where the positioning block is provided with the arc-shaped rubber pad.

[0013] Preferably, a mounting plate is connected to the outer side of the magnifying glass, and a fixing ring is fixedly connected to the rear side of the mounting plate. The longitudinal section of the fixing ring is L-shaped, and the fixing ring is rotatably connected in the rotating groove. When viewing the patient's imaging film, the layout image can be magnified by adjusting the position of the magnifying glass, which is convenient for doctors to view or for giving instructions to the patient.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the magnifying glass can move smoothly laterally along the guide rail by relying on the first slide and the first guide wheel. The second slide can be flexibly adjusted longitudinally along the guide axis by the second guide wheel. Through the bidirectional adjustment of the horizontal and vertical positions, the magnifying glass can be quickly and accurately aimed at any target position of the image, which is convenient for doctors to observe the details of the lesion in detail and can also intuitively point out the location of the lesion to the patient, effectively improving the efficiency of diagnosis and image reading and the accuracy of doctor-patient communication.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-7 As shown, this utility model provides an adjustable universal medical image reading device, including a lamp cabinet 1. A light-transmitting panel 2 is fixedly connected to the front end face of the lamp cabinet 1. Multiple power buttons 3 are fixedly connected to the lamp cabinet 1 below the light-transmitting panel 2. The power buttons 3 are electrically connected to the main controller inside the lamp cabinet 1 via wires. Guide rails 4 are fixedly connected to the top and bottom of the lamp cabinet 1. An image magnification mechanism 5 is provided between the two guide rails 4. The image magnification mechanism 5 includes a first slide 6 movably connected to the guide rail 4. A sub-plate 8 is fixedly connected to the first slide 6. Two guide shafts 9 are fixedly connected between the two sub-plates 8. A second slide 10 is movably connected between the two guide shafts 9. Two positioning blocks 11 are symmetrically movably connected to the rear side of the second slide 10. A mounting sleeve 12 is fixedly connected to the front side of the second slide 10. An operating handle 13 is inserted and connected to the mounting sleeve 12 and the second slide 10. The rear side of the operating handle 13 extends between the two positioning blocks 11 and is fixedly connected to a trapezoidal block 14. A magnifying glass 15 is movably connected to one side of the second slide 10.

[0026] like Figures 1-2As shown, the bottom of the first slide 6 is rotatably connected to several first guide wheels 7, and the first slide 6 is slidably connected to the guide rail 4 through the several first guide wheels 7. The first guide wheels 7 are rubber wheels. When the two first slides 6 are pushed and pulled synchronously by the second slide 10, the two guide shafts 9 and the sub-plate 8, the first slide 6 can slide on the corresponding guide rail 4 with the help of the bottom first guide wheels 7. The first guide wheels 7 are rubber wheels, which can provide a certain damping for the movement of the first slide 6, and facilitate the adjustment and positioning of the first slide 6.

[0027] like Figures 3-7As shown, a number of second guide wheels 16 are rotatably connected to the rear side of the second slide 10. The second slide 10 is slidably connected between two guide shafts 9 via the number of second guide wheels 16. Thus, the second slide 10 moves in the Y direction between the two guide shafts 9 by means of the number of second guide wheels 16, while the guide shafts 9 can move in the X direction at the front of the lamp cabinet 1 by means of the sub-plate 8 and the first slide 6, thereby facilitating quick adjustment of the setting position of the magnifying glass 15. A rotating groove 18 is formed on the front side of the second slide 10 with the mounting sleeve 12 as the center. A support block 27 is fixedly connected to the second slide 10 located below the rotating groove 18, thereby... The support block 27 can limit the rotation of the mounting plate 25, allowing the magnifying glass 15 to rotate around the fixing ring 26. Several limiting screws 17 are threaded onto the rear side of the second slide 10, and a limiting cap 20 is threaded onto the front side of the mounting sleeve 12. This facilitates the assembly of the operating handle 13 with the second slide 10 and the mounting sleeve 12. Simultaneously, the limiting cap 20 provides a base point for the operator's hand when the operating handle 13 is pressed, allowing the second slide 10 to be pushed and pulled up and down via the mounting sleeve 12. Two linear grooves 19 are formed within the positioning block 11, and slopes are provided on opposite sides of the two positioning blocks 11. The trapezoidal block 14 has a T-shaped groove 21 and a linear groove 19 slidably connected to one of the limiting screws 17. This allows the positioning block 11 to slide horizontally on the two limiting screws 17 via the two internal linear grooves 19 under the push-pull operation of the trapezoidal block 14. An arc-shaped rubber pad is provided on the side of the positioning block 11 opposite to the guide shaft 9 to increase the friction with the guide shaft 9, thereby enabling the second slide table 10 to be positioned at any position between the two guide shafts 9. Both sides of the trapezoidal block 14 have sloped surfaces and are fixedly connected to T-shaped sliders 22. The side of the operating handle 13 away from the trapezoidal block 14 is fixedly connected to a limiting screw. Positioning ring 23, T-shaped slider 22 and one of T-shaped slide grooves 21 are slidably connected to each other. The limiting ring 23 is inserted into the mounting sleeve 12 through the operating handle 13. The operating handle 13 located between the limiting ring 23 and the second slide 10 is also fitted with a spring 24. With the push force of the spring 24 on the limiting ring 23, the limiting ring 23 can provide a continuous pulling force to the trapezoidal block 14 in the direction of the second slide 10 through the operating handle 13. Thus, the trapezoidal block 14, with the slopes on both sides corresponding to one side of the positioning block 11, causes the side of the positioning block 11 with the arc-shaped rubber pad to press against the outside of the guide shaft 9.

[0028] like Figure 7 As shown, a mounting plate 25 is connected to the outside of the magnifying glass 15, and a fixing ring 26 is fixedly connected to the rear side of the mounting plate 25. The longitudinal section of the fixing ring 26 is L-shaped, and the fixing ring 26 is rotatably connected in the rotating groove 18. When viewing the patient's imaging film, the layout image can be magnified by adjusting the position of the magnifying glass 15, which is convenient for doctors to view or to give instructions to the patient.

[0029] It should be noted that this utility model is an adjustable universal medical image viewing device. After the CT film is mounted into the lamp cabinet 1, the power button 3 is pressed to start the device, and the LED light source in the lamp cabinet 1 is lit up. When it is necessary to view the lesion in a specific cell of the film, the mounting sleeve 12 is held with two fingers of one hand. The mounting sleeve 12 is linked to the second slide 10, the guide shaft 9 and the auxiliary plate 8, which drives the two first slides 6 to slide horizontally along the guide rail 4 by the first guide wheel 7 at the bottom, thus completing the coarse adjustment of the X-axis position of the magnifying glass 15. After the X-axis position is determined, the operating handle 13 is pressed to move the trapezoidal block 14 towards the second slide 10. By utilizing the slope of the trapezoidal block 14 and the positioning block 11, the two positioning blocks 11 are pushed to slide relative to each other along the limiting screw 17, so that the arc-shaped rubber pad on the positioning block 11 is disengaged from the guide shaft 9. At this time, while keeping the operating handle 13 pressed, the mounting sleeve 12 is pushed to move the second slide 10. The second guide wheel 16 on the rear side of the second slide 10 will slide smoothly along the guide shaft 9 to realize the vertical adjustment of the magnifying glass 15. Simultaneously, the first slide 6 can be moved through the guide shaft 9 and the sub-plate 8 to complete the horizontal fine adjustment of the magnifying glass 15. Thus, the magnifying glass 15 can be quickly aligned with the target lesion area through the horizontal and vertical bidirectional adjustment.

[0030] After adjustment, release the operating handle 13. The rebound force of the spring 24 pushes the limit ring 23 to reset. The operating handle 13 drives the trapezoidal block 14 to move back. With the help of the slope, the positioning block 11 is pushed to make tight contact with the guide shaft 9. The second slide 10 is stably positioned by the contact friction, ensuring that the position of the magnifying glass will not shift during the film reading process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
