Description

Technical Field

[0001] This utility model relates to the field of medical color film technology, specifically to an antistatic medical film. Background Technology

[0002] Medical laser film, also known as medical infrared laser imaging film, is formed by coating a photosensitive emulsion layer on the front and an anti-halo layer on the back of a blue polyester film base. It is a medical imaging film used for infrared laser photography and is suitable for infrared laser cameras with a laser light source range of 780nm to 830nm. It can be used in medical imaging diagnostic techniques such as CT, MRI, CR, DR, DV, and DSA.

[0003] When the film is not in use, the external film accumulates a large amount of charge on the imaging layer due to friction, generating static electricity. This static electricity affects the imaging effect of the film, causing blurry images and making it inconvenient to read the film. It is necessary to remove static electricity before use. Conventional wiping methods can easily scratch and damage the film surface, which also affects the imaging effect. Therefore, it is particularly important to improve existing medical color films and design a new type of antistatic medical film to solve the above-mentioned technical defects and improve the overall practicality of medical color films. Utility Model Content

[0004] The purpose of this invention is to provide an antistatic medical film. When the film body is in use, the antistatic layer can increase the antistatic effect of the film body, effectively conduct static electricity on the film body to the outside, effectively reduce the impact of static electricity generated during the printing process on the film body, and prevent it from affecting the imaging effect of the film body, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An antistatic medical film includes a film body with a connecting groove inside and a receiving groove extending into the film body. The film body is composed of a base layer, a base adhesive layer, an imaging layer, a first waterproof layer, an antistatic layer, and a second waterproof layer. The base adhesive layer is fixedly connected to the outside of the base layer, the imaging layer is fixedly connected to the end of the base adhesive layer away from the base layer, the first waterproof layer is fixedly connected to the end of the imaging layer away from the base adhesive layer, the antistatic layer is fixedly connected to the end of the first waterproof layer away from the imaging layer, and the second waterproof layer is fixedly connected to the end of the antistatic layer away from the first waterproof layer.

[0007] The antistatic layer is used to increase the antistatic effect of the film body. The antistatic layer includes multiple sets of antistatic particles fixedly connected between the first waterproof layer and the second waterproof layer. Conductive wires are fixedly connected to both ends of the multiple sets of antistatic particles and fixedly connected between the first waterproof layer and the second waterproof layer. The antistatic layer also includes two sets of conductive blocks fixedly connected to the outside of the film body.

[0008] Both the first and second waterproof layers are used to enhance the waterproof effect of the film body.

[0009] As a preferred embodiment of this utility model, the two sets of conductive blocks are respectively fixedly connected to two sets of conductive lines.

[0010] As a preferred embodiment of this utility model, the multiple sets of antistatic particles are distributed at equal intervals between the first waterproof layer and the second waterproof layer, and the thickness of the antistatic particles is 2-3 μm.

[0014] As a preferred embodiment of this utility model, both sets of transparent waterproof membranes have a latex adhesive layer at one end near the antistatic layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the antistatic layer is designed to form a complete conductive path through antistatic particles, conductive lines, and conductive blocks. Static electricity accumulates in the imaging layer, is collected by the antistatic particles, and then transmitted to the conductive blocks on the outside of the film through conductive rubber conductive lines, where it is finally released to the outside. The conductive rubber properties of the conductive lines and blocks combine flexibility and conductivity, avoiding the damage to the film structure caused by traditional metal materials. The antistatic particles 10 are evenly distributed with a thickness of 2-3 μm to ensure uniform static electricity discharge while avoiding affecting optical imaging performance. The waterproof layer provides double protection through a transparent waterproof membrane and a latex adhesive layer, blocking the water vapor penetration path and protecting the functional stability of the antistatic layer. The real-time static electricity discharge mechanism avoids the imaging blurring problem caused by charge accumulation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-3 This utility model provides a technical solution:

[0024] An antistatic medical film includes a film body 1, with a connecting groove 2 inside the film body 1, and the connecting groove 2 extending into a receiving groove 3 inside the film body 1. The film body 1 is composed of a base layer 4, a base adhesive layer 5, an imaging layer 6, a first waterproof layer 7, an antistatic layer 8, and a second waterproof layer 9. The base adhesive layer 5 is fixedly connected to the outside of the base layer 4, the imaging layer 6 is fixedly connected to the end of the base adhesive layer 5 away from the base layer 4, the first waterproof layer 7 is fixedly connected to the end of the imaging layer 6 away from the base adhesive layer 5, the antistatic layer 8 is fixedly connected to the end of the first waterproof layer 7 away from the imaging layer 6, and the second waterproof layer 9 is fixedly connected to the end of the antistatic layer 8 away from the first waterproof layer 7.

[0025] The antistatic layer 8 is used to increase the antistatic effect of the film body 1. The antistatic layer 8 includes multiple sets of antistatic particles 10 fixedly connected between the first waterproof layer 7 and the second waterproof layer 9. Conductive wires 11 are fixedly connected to both ends of the multiple sets of antistatic particles 10 and fixedly connected between the first waterproof layer 7 and the second waterproof layer 9. The antistatic layer 8 also includes two sets of conductive blocks 12 fixedly connected to the outside of the film body 1.

[0026] Both the first waterproof layer 7 and the second waterproof layer 9 are used to enhance the waterproof effect of the film body 1;

[0027] Furthermore, the two sets of conductive blocks 12 are fixedly connected to the two sets of conductive lines 11 respectively. Multiple sets of antistatic particles 10 are evenly distributed between the first waterproof layer 7 and the second waterproof layer 9, and the thickness of the antistatic particles 10 is 2-3 μm. The conductive lines 11 and conductive blocks 12 are rubber conductive lines and rubber conductive blocks, respectively, and the rubber is conductive rubber. A complete conductive path is formed through the antistatic particles 10, conductive lines 11, and conductive blocks 12. Static electricity accumulates in the imaging layer 6, is collected by the antistatic particles 10, and is transferred to the conductive blocks 12 on the outside of the film through the conductive rubber conductive lines 11. Released to the outside world, the conductive rubber properties of the conductive wires 11 and conductive blocks 12 combine flexibility and conductivity, avoiding the damage to the film structure caused by traditional metal materials. The antistatic layer 8 is sandwiched between two waterproof membranes, and the antistatic particles 10 are evenly distributed at 2-3μm thickness to ensure uniform static discharge while avoiding affecting optical imaging performance. The waterproof layer is doubly protected by a transparent waterproof membrane and a latex adhesive layer, blocking the water vapor penetration path and protecting the functional stability of the antistatic layer 8. The real-time static discharge mechanism avoids the imaging blurring problem caused by charge accumulation, making it especially suitable for high-precision medical image output such as CT and MRI. The flexible conductive rubber material reduces friction damage, and together with the waterproof layer design, extends the film's service life. Compared with traditional wiping methods for removing static electricity, it avoids the risk of scratches.

[0028] Furthermore, both the first waterproof layer 7 and the second waterproof layer 9 are composed of transparent waterproof membranes. The two sets of transparent waterproof membranes are fixedly connected to both ends of the antistatic layer 8. The first waterproof layer 7 and the second waterproof layer 9 are both made of transparent waterproof membrane material and cover the upper and lower sides of the antistatic layer 8 respectively, forming a double-layer waterproof barrier. The transparent waterproof membrane blocks water vapor penetration through its dense polymer structure, preventing external moisture from entering the film. The superimposed design of the two waterproof membranes further reduces the probability of water vapor penetration. Even if a single layer fails locally, the overall waterproof performance can still be maintained, effectively isolating water vapor from eroding the imaging layer 6 and the antistatic layer 8, preventing abnormal development or failure of the static discharge function caused by moisture in the emulsion. Compared with the traditional single-layer waterproof design, the double-layer structure significantly improves the reliability in humid environments.

[0029] Furthermore, each of the two sets of transparent waterproof membranes has a latex adhesive layer at one end near the antistatic layer 8. When the film body 1 is in use, the two sets of transparent waterproof membranes can prevent water vapor from penetrating into the interior of the film body 1. The two sets of transparent waterproof membranes can form two waterproof effects. Together with the latex adhesive layer, they can provide waterproofing to the film body 1 from the outside again, thereby preventing water vapor from penetrating into the interior of the film body 1 and affecting its use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
