TECHNICAL FIELD

[0001] The utility model relates to medical operation film technical field especially a kind of tear-free medical operation film. BACKGROUND

[0002] Medical operation film is generally composed of polyethylene (PE) film, polyether sulfone (TPE) film, polyurethane (PU) film or thermoplastic polyurethane (TPU) film, which has a uniform coating of pressure-sensitive adhesive on the surface of the surgical film, a protective layer on the adhesive surface, and a handle on both sides of the surgical film for manual operation.

[0003] Currently, medical operation film is used with surgical drapes, and some hospitals use reusable surgical drapes. After the operation is completed, medical staff need to peel off the medical operation film from the surgical drape, which increases the workload of medical staff and reduces the efficiency of the operation. At the same time, it increases the contact between medical staff and the used and contaminated medical operation film and surgical drape, and increases the risk of infection. To overcome the above-mentioned defects, the present application is proposed. SUMMARY

[0004] The utility model aims to provide a kind of tear-free medical operation film, which does not require medical staff to peel off the medical operation film from the surgical drape, thereby reducing the workload of medical staff and the risk of infection.

[0005] To solve the above problems, the utility model provides a kind of tear-free medical operation film, which includes a film layer, a protective layer and a glue layer. The glue layer is arranged on the film layer. The glue layer uses heat-losing adhesive, which loses adhesion after being heated to a certain temperature. After losing adhesion, the medical operation film is separated from the surgical drape.

[0006] According to an embodiment of the utility model, the film layer is made of high-temperature-resistant film.

[0007] Preferably, the minimum tolerance temperature should be greater than the debonding temperature of the heat-losing adhesive.

[0008] Preferably, the film layer is PU film, which can withstand about 150℃.

[0009] Optionally, the heat-losing adhesive is heat-losing pressure-sensitive adhesive, which can also use hot melt adhesive, polymer adhesive, etc.

[0010] According to an embodiment of the utility model, the debonding temperature of the heat-losing adhesive is 75~85℃, which can lose adhesion during heat washing and disinfection, and achieve the separation of the surgical film and the surgical drape during washing.

[0011] According to an embodiment of the utility model, the grammage of the glue layer is at least 25g / m 2 .

[0012] According to an embodiment of the present application, the medical operation film without tearing removal further comprises a handle.

[0013] Optionally, the handle is arranged on the protective layer or the film layer.

[0014] According to an embodiment of the present application, two handles are arranged, and each handle is arranged at the two ends of the protective layer.

[0015] The present application has the advantages that the film with a hot debonding adhesive is developed, after the film is combined with the surgical sheet, the adhesive layer is debonded by heating, and the film is separated from the surgical sheet, so that the medical staff does not need to manually peel the film from the surgical sheet, the workload of the medical staff is reduced, the contact between the medical staff and the used contaminated film and surgical sheet is reduced, and the risk of contact infection is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0016] The present application will be further described below in combination with the drawings and embodiments.

[0017] Figure 1 The overall structure of the medical operation film without tearing removal is shown in the figure. DETAILED DESCRIPTION

[0018] The following description is only used to disclose the present application so that those skilled in the art can implement the present application. The embodiments in the following description are only examples, and those skilled in the art can think of other obvious modifications. The basic principles of the present application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents and other solutions without departing from the spirit and scope of the present application.

[0019] Embodiment 1

[0020] A medical operation film without tearing removal, like Figure 1 , comprises a film layer 1, a protective layer 2 and an adhesive layer, the adhesive layer is arranged on the film layer 1, the adhesive layer adopts a hot debonding adhesive, the hot debonding adhesive loses adhesion after being heated to a certain temperature, and the medical operation film is separated from the surgical sheet after losing adhesion.

[0021] The film layer 1 adopts a high-temperature-resistant film, and the minimum tolerance temperature of the film is greater than the debonding temperature of the hot debonding adhesive, so that deformation is avoided during subsequent high-temperature washing. In the present embodiment, a PU film is used as the film layer 1, and can resist about 150 DEG C.

[0022] The hot debonding adhesive adopts a hot debonding pressure-sensitive adhesive, which is a pressure-sensitive adhesive that can be normally attached and used at room temperature, and loses adhesion rapidly under high-temperature conditions.

[0023] According to the WST 508-2016 hospital medical fabric washing and disinfection technical specification, the surgical drape can be washed in hot water during the washing process, and the hot washing temperature is 70-90℃, therefore, the preferred 75~85℃ hot debonding pressure sensitive adhesive is applied to the medical surgical film in this embodiment, so that when the used surgical film is washed according to the WST 508-2016 hospital medical fabric washing and disinfection technical specification, the medical surgical film will lose adhesion and be washed off from the surgical drape, so as to achieve the washing effect of the surgical drape.

[0024] Other ways can also be used to achieve hot debonding, such as hot air gun, and the corresponding hot debonding adhesive with corresponding temperature can be used.

[0025] Preferably, as Figure 1 The tear-free medical surgical film also includes a handle 3, which is provided in two groups and is arranged at both ends of the protective layer 2, so that the overall length of the protective layer 2 is greater than the length of the film layer 1, facilitating the tearing of the protective layer 2 during use. In other embodiments, an easy-to-pull structure can also be provided on the outer surface of the protective layer 2.
