Description

Technical Field

[0001] The utility model relates to the technical field of thermal films, in particular to a medical thermal film. Background Art

[0002] Medical thermal film is an imaging material that plays an important role in medical imaging. It uses thermal imaging technology to improve the accuracy of disease diagnosis and provide a basis and support for treatment. The structure of this film consists of a thermal film body, a protective layer, a fluorescent coating, an imaging layer, an absorption layer, an isolation layer, microcapsules, fillers, gelatin, a polyester film base, etc.

[0003] When printing current medical films, the outermost protective layer needs to be peeled off or torn off. The outermost two layers of some thermal films are the imaging layer and the fluorescent coating. The protective layer is attached to the outermost layer to provide isolation protection, which makes the imaging outer layer of the film easily contaminated during transfer or circulation between departments. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A medical thermal film, comprising:

[0007] A film portion and an assembly frame surrounding the outside thereof; a protective ring surrounding the outside of the assembly frame, the inner wall of the protective ring being slidably assembled with the outer wall of the assembly frame, and the protective ring being rotatably wound around the outer wall of the assembly frame; a hollow window is provided on the protective ring, and the size of the hollow window is equal to the size of the imaging layer of the film portion; a locking piece for locking the protective ring is designed on the assembly frame; in the printing state, the hollow window is rotated to be directly above the imaging layer of the film portion; in the isolation state, the hollow window is rotated to be directly below the imaging layer of the film portion.

[0010] Optionally, the arc-shaped flanges are designed to be multiple, the assembly grid is designed to have multiple grid feet, and the grid feet and the arc-shaped flanges are designed to be staggered.

[0011] Optionally, the frame wall height of the assembly frame is greater than the thickness of the film portion, and a design of an intermediate bottom and peripheral height is formed between the assembly frame and the film portion.

[0012] Optionally, a transparent layer is fixedly mounted on the inner wall of the hollow window, and the outer wall of the transparent layer is in the same plane as the outer wall of the protective ring.

[0017] 1. By designing the coordination of the protective ring, the assembly frame and the hollow window, when printing or viewing is required, the protective ring only needs to be rotated to move the hollow window to the top of the imaging layer, so that the printing device can use the opening of the hollow window to develop the imaging layer, or the patient or medical staff can use and view the imaging layer through the hollow window. When the film part is to be stored, transported or protected, the hollow window needs to be rotated to the bottom of the imaging layer so that the protective ring can provide protection for the imaging layer and act as a protective layer.

[0018] Second, the sliding fit between the embedded groove and the ribs can provide guidance for the sliding of the protective ring. Secondly, by designing an embedded assembly, the intrusion of external pollutants can be reduced, and a certain sealing protection function can be achieved.

[0019] Third, by designing an assembly grid that can be displaced outward in the assembly frame, the assembly grid will exert pressure on the protective ring during its outward displacement, making it tight, so that the protective ring can exert pressure on the assembly frame to maintain a close fit, ensuring that the protective ring can provide stable protection for the imaging layer.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 7 The utility model provides a technical solution: a medical thermal film, comprising:

[0030] A film portion 1 and an assembly frame 2 surrounding the outside thereof; a protective ring 3 surrounding the outside of the assembly frame 2, the inner wall of the protective ring 3 being slidably assembled with the outer wall of the assembly frame 2, and the protective ring 3 being rotatably wound around the outer wall of the assembly frame 2; a hollow window 6 is provided on the protective ring 3, and the size of the hollow window 6 is equal to the size of the imaging layer of the film portion 1; a locking piece for locking the protective ring 3 is designed on the assembly frame 2; in the printing state, the hollow window 6 is rotated to be directly above the imaging layer of the film portion 1; in the isolation state, the hollow window 6 is rotated to be directly below the imaging layer of the film portion 1.

[0031] In the prior art, doctors and patients may accidentally touch the imaging layer or the outermost layer of the film part 1 directly, resulting in contamination such as fingerprints, or in the process of long-term use, the outermost layer of the film part 1 is easily contaminated by various factors, such as oil and medicine. In the utility model, by designing an assembly frame 2 surrounding the outside of the film part 1, the assembly frame 2 provides support for the film part 1, and the film part 1 is used as a rotation support, so that the protective ring 3 can be rotated. The outer wall of the assembly frame 2 is designed so that the protective ring 3 can provide protection for the outermost part of the imaging part of the film part 1. Secondly, since the protective ring 3 is provided with The hollow window 6, when printing or viewing is required, the protective ring 3 only needs to be rotated to move the hollow window 6 to the top of the imaging layer, so that the printing device can use the opening of the hollow window 6 to develop the imaging layer, or the patient or medical staff can use and view the imaging layer through the hollow window 6. When the film unit 1 is to be stored, transported or protected, the hollow window 6 needs to be rotated to the bottom of the imaging layer so that the protective ring 3 can provide protection for the imaging layer and act as a protective layer. Therefore, the utility model can reuse the protective layer without tearing or peeling it off, and it will not interfere with normal printing, viewing and storage.

[0032] By designing the lock, the protection ring 3 can be locked in an isolated state or a printing state.

[0033] In a more preferred embodiment, an outer wall at the edge of the assembly frame 2 is provided with an embedded groove 5 along the rotation path of the protection ring 3, and a rib 7 is integrally formed on the annular inner wall of the protection ring 3. The rib 7 is slidably assembled with the embedded groove 5, see Figure 3 , Figure 5 and Figure 6 In this embodiment, the sliding cooperation between the embedded groove 5 and the rib 7 can provide guidance for the sliding of the protective ring 3. Secondly, by designing an embedded assembly, the intrusion of external pollutants can be reduced, and a certain sealing protection function can be achieved.

[0034] In a preferred embodiment, the lock comprises an assembly groove provided inside the assembly frame 2, in which an assembly strip 11 is slidably installed, an arc-shaped flange is integrally formed on the outer wall of the assembly strip 11, and an assembly grid 12 is slidably passed through the inner wall of the assembly groove, and the end of the assembly grid 12 passing through the assembly frame 2 is in the same plane as the side wall of the assembly frame 2, and when the assembly strip 11 slides, its arc-shaped flange contacts the assembly grid 12 and causes the assembly grid 12 to move outward, so that the protective ring 3 is tightened, see Figure 4And its detailed enlarged view, in this embodiment, the protection ring 3 is rotatably wound on the outer wall of the assembly frame 2. When not in the printing state, it is necessary to ensure that the protection ring 3 can stably provide protection for the imaging layer, and a mounting grid 12 that can be displaced outward is designed in the assembly frame 2. The process of the mounting grid 12 displacing outward will exert pressure on the protection ring 3 to make it tight, so that the protection ring 3 can exert pressure on the assembly frame 2 to maintain a close fit, wherein, during the displacement process of the assembly bar 11, the arc-shaped flange can use its transformed outer wall to resist the assembly grid 12, so that it can be displaced outward, on the contrary, after the assembly bar 11 is reset, the protection ring 3 will make the assembly grid 12 return to the assembly groove.

[0035] Furthermore, in order to improve the operating stability and smoothness of the lock, multiple arc-shaped flanges are designed, and multiple gate feet of the assembly gate 12 are designed, and the gate feet and the arc-shaped flanges are staggered. The gate feet and the arc-shaped flanges are distributed in an equidistant array, which is convenient for manufacturing and overall transmission, and improves the smoothness of transmission.

[0036] In a more preferred embodiment, the height of the frame wall of the assembly frame 2 is greater than the thickness of the film portion 1, and a design of a middle bottom peripheral height is formed between the assembly frame 2 and the film portion 1, see Figure 3 As shown in the enlarged detail diagram, there is a height difference between the film portion 1 and the assembly frame 2, so the protective ring 3 is not in contact with the outermost layer of the film portion 1, thereby avoiding friction between the outermost layer of the film portion 1 and the protective ring 3. The film portion 1 will rotate the protective ring 3 during use, so the rotation of the protective ring 3 will not affect the outermost layer of the film portion 1.

[0037] Furthermore, a transparent layer 13 is fixedly mounted on the inner wall of the hollow window 6, and the outer wall of the transparent layer 13 is in the same plane as the outer wall of the protective ring 3, see Figure 7 As shown in the enlarged view of its details, in the present embodiment, the opening of the hollow window 6 may cause external pollution to the imaging layer of the film portion 1. In order to reduce the pollution, a transparent layer 13 is designed. When the hollow window 6 and the transparent layer 13 are rotated to be directly above the imaging layer, the transparency of the transparent layer 13 will not interfere with the printing process and will not interfere with the viewing of patients or medical staff.

[0038] Furthermore, in order to enable the protection ring 3 to slide more smoothly on the outer wall of the assembly frame 2, the edge lines of the assembly frame 2 are all designed with rounded corners.

[0039] In order to avoid contact between the protective ring 3 and the film portion 1 or to reduce the generation of static electricity, the imaging layer of the film portion 1 is also coated with an antistatic layer.

[0040] Furthermore, an inspection port 9 is provided on the outer wall of the assembly frame 2 , which is connected to the inner wall of the assembly frame 2 , and the winding of the hollow window 6 does not interfere with the connection of the inspection port 9 , so that the internal film part 1 can be loaded, pasted or taken out through the inspection port 9 .

[0041] By using the above structures, the protective layer can be reused without tearing or peeling, and it will not interfere with normal printing, viewing and storage.

[0042] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
