Abstract
Description
Technical Field
[0001] This utility model relates to the field of surgical film technology, specifically to an easy-to-tear ophthalmic surgical film. Background Technology
[0002] As a major country in ophthalmic surgery, my country performs a large number of ophthalmic surgeries every year. Surgical dressings are a crucial part of pre-operative preparation. During ophthalmic surgery, to keep the surgical area clean and dry and prevent infection, surgical dressings are typically used to cover the area around the patient's eyes. This simplifies pre-operative skin care, prevents contact and migratory surgical wound infections, and provides a relatively isolated and stable area for the surgical procedure. Traditional dressings adhere tightly to the skin and lack an easy-to-tear design. Removing them can easily cause significant pulling force on the skin, resulting in pain. Furthermore, the edges of the dressing often do not adhere well to the surgical drape, easily folding and curling, which can cause gloves to stick to the surgeon's gloves, affecting the surgical procedure. Therefore, this application is submitted. Utility Model Content
[0003] This application proposes an easy-to-tear ophthalmic surgical film to solve the problems of existing films that adhere tightly to the skin, lack easy-to-tear design, easily exert significant pulling force on the skin during removal, causing pain, and often have poor adhesion between the film edges and surgical drapes, easily folding and curling, which can cause gloves to stick to the surgeon's gloves and affect the surgical procedure. The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0004] An easy-to-tear ophthalmic surgical film includes a film, an adhesive layer, dimples, a glossy paper, and a sticker. The adhesive layer is disposed on one side of the film. The dimples are evenly spaced on one side of the adhesive layer on the film. The depth of the dimples is 1 / 3 to 1 / 2 of the film thickness. The spacing between the dimples is 0.5 to 1.5 mm. The dimples are arranged in a square array.
[0005] Furthermore, one end of the film is provided with a liquid receiving bag, and the liquid receiving bag has a cavity inside.
[0006] Furthermore, one end of the film is provided with a supporting rib, and the liquid receiving bag is connected to the supporting rib.
[0007] Furthermore, the film is a transparent polyurethane film.
[0008] Furthermore, the adhesive layer is a medical-grade acrylic pressure-sensitive adhesive.
[0009] Furthermore, the shape of the concave point is one of the regular shapes such as circle, ellipse or polygon.
[0010] Furthermore, the thickness of the adhesive layer is 0.01-0.03 mm.
[0011] Compared with the prior art, the beneficial effects of this utility model include:
[0012] By designing small indentations and residual stickers at the ends, the indentations are non-penetrating holes, which not only do not affect the film's antibacterial effect but also make the film easy to tear. This makes the surgical film easier to tear and can disperse stress, thereby reducing the pain for patients during the film removal process. This not only improves the smoothness of the operation but also increases patient satisfaction. By placing stickers at the ends of the film, the film can be prevented from curling or folding back during the operation. After the operation, it can also serve as a starting point for tearing, allowing medical staff to easily start tearing the film from this point, further improving the convenience of film removal.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0020] Please see the appendix Figure 1-3 An easy-to-tear ophthalmic surgical film includes a film 1, an adhesive layer 2, dimples 3, a glossy paper 4, and a sticker 5. The adhesive layer 2 is disposed on one side of the film 1, and the dimples 3 are evenly spaced on one side of the adhesive layer 2 on the film 1. The depth of the dimples 3 is 1 / 3 to 1 / 2 of the film thickness, the spacing between the dimples 3 is 0.5-1.5 mm, and the dimples 3 are arranged in a square array.
[0021] The design of the small dimples 3, employing the above technical solutions, is based on a comprehensive consideration of materials mechanics and ergonomics. The small dimples 3, evenly distributed on the surface of the film, can alter the stress distribution when the film contacts the skin. When medical personnel attempt to peel off the film, these small dimples 3 act as stress dispersion points, preventing the tearing force from concentrating at a single point but distributing it across the entire film surface. This results in a more uniform tearing force, reducing the irritation to the skin from sudden increases in tearing force, thereby alleviating patient pain. The dimples 3 are arranged in a square array, ensuring that stress in each direction is evenly distributed during the tearing process. This arrangement also improves the overall stability of the film, preventing tearing or deformation during the tearing process.
[0022] The remaining sticker at the end 5 can prevent the film from curling or folding back during the procedure. After the procedure, it can also serve as the starting point for tearing. The end sticker 5 is disconnected from the main sticker 5 of the film, but they are made of the same material, so they can maintain a tight fit with the main film when in use.
[0023] When applying the film, medical staff can leave part 5 of the end sticker outside the surgical drape for easy removal after the surgery. When it is necessary to remove the film, medical staff can easily pinch part 5 of the end sticker and start tearing from there, which further improves the convenience of removing the film.
[0024] In detail, based on a comprehensive consideration of the surgical field of vision and the adhesion of the film, the thickness of the main body of the film is between 0.05 and 0.15 mm. If the film is too thick, it will obstruct the surgical field of vision and affect the doctor's operation; while if the film is too thin, it may not be able to provide sufficient barrier effect. Therefore, the thickness range in this application can ensure that the film provides sufficient barrier effect without obstructing the surgical field of vision.
[0025] In some embodiments, one end of the film 1 is provided with a liquid-receiving bag 6, and the liquid-receiving bag 6 has a cavity 7 inside. During ophthalmic surgery, blood, tears, or other bodily fluids may flow around the patient's eyes. The design of the liquid-receiving bag 6 can effectively collect these fluids and prevent them from flowing into the surgical area or other parts of the patient, thereby keeping the surgical area clean and dry. The cavity 7 inside the liquid-receiving bag 6 can hold a certain amount of fluid, preventing fluid from spilling and contaminating the surgical environment or the patient's clothing, reducing the risk of infection during the surgery, and improving the safety of the surgery.
[0026] In some embodiments, one end of the film 1 is provided with a supporting rib 8, and the liquid collection bag 6 is connected to the supporting rib 8. This provides stable support for the liquid collection bag 6, allowing it to fit securely around the patient's eye. The supporting rib 8 also maintains the shape and stability of the liquid collection bag 6, preventing it from deforming or collapsing due to gravity even after a certain amount of liquid has been collected.
[0027] In some embodiments, film 1 is a transparent polyurethane film 1. Medical-grade transparent polyurethane material can closely adhere to the skin around the eyes, forming an effective barrier to prevent bacteria and other microorganisms from entering the surgical area. At the same time, its good breathability ensures that the skin remains comfortable even after prolonged contact.
[0028] In some embodiments, the adhesive layer 2 is a medical-grade acrylic pressure-sensitive adhesive, and the thickness of the adhesive layer 2 is 0.01-0.03 mm. The adhesive layer 2 uses medical-grade acrylic pressure-sensitive adhesive, which can firmly adhere to the skin around the eyes, ensuring that the film will not fall off or shift during the procedure. At the same time, when peeled off, this adhesive can be relatively easily separated from the skin without leaving excessive residue or causing damage to the skin.
[0029] Specifically, the thickness of adhesive layer 2 is between 0.01 and 0.03 mm, ensuring that it provides sufficient adhesion without increasing the overall thickness of the film. An excessively thick adhesive layer 2 might increase the resistance during peeling, reducing the ease of removal; while an excessively thin adhesive layer 2 might not provide sufficient adhesion. Therefore, an adhesive layer 2 thickness between 0.01 and 0.03 mm ensures that it provides sufficient adhesion without increasing the overall thickness of the film or the difficulty of peeling.
[0030] In some embodiments, the shape of the concave point 3 is one of a regular shape such as a circle, an ellipse, or a polygon.
[0031] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
