Description

TECHNICAL FIELD

[0001] The utility model relates to medical supplies technical field, concretely relates to a novel medical application adhesive tape. BACKGROUND

[0002] Medical adhesive tape, also known as medical adhesive tape, is a common medical device product, which is widely used in the medical field. It is composed of adhesive tape base material and adhesive. Medical adhesive tape plays a role in fixing, protecting and repairing in the medical process, and is widely used in wound dressing fixation, catheter fixation, joint support and other aspects. Medical adhesive tape is often used in wound dressing and dressing fixation in medical scenarios. After treating the wound, the wound is dressed with medical adhesive tape to facilitate the protection and healing of the wound. The existing medical adhesive tape is usually in the form of a long strip. When using the medical adhesive tape, the medical adhesive tape is unfolded and used to dress the wound, and then scissors are used for cutting.

[0003] However, due to the different parts of the affected area, the existing medical adhesive tape cannot meet the use requirements. For example, when used on the affected area of the head with more hair, the medical adhesive tape is difficult to remove due to the pulling of the hair by the adhesive tape, causing pain to the patient. For example, when used on the joint part and other parts with large curvature, the medical adhesive tape does not fit the skin well, resulting in poor adhesion of the medical adhesive tape. The existing medical adhesive tape has poor adaptability to different parts of the wound. The present scheme solves this technical problem. CONTENT OF THE UTILITY MODEL

[0004] In view of the shortcomings of the prior art, the utility model provides a novel medical application adhesive tape, which is safe and reliable for adhesion to wounds in different parts, has better use effect, better air permeability, and reduces the discomfort symptoms such as skin allergy, redness and itching caused by long-term use.

[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme: a novel medical application adhesive tape, comprising a base layer, a glue layer adhered to one side of the base layer, and a release paper adhered to the other side of the glue layer, wherein the release paper is provided with a plurality of horizontal and vertical tear lines, and the base layer is provided with a base layer tear line corresponding to the vertical tear line.

[0006] More specifically, the base layer is made of polyurethane film, and the glue layer is made of acrylic adhesive.

[0007] A plurality of air holes are arranged in an array on the base layer, the glue layer is coated on the base layer in a grid shape, and the glue layer avoids the plurality of air holes.

[0008] The existing medical adhesive tape has the problem of poor air permeability, and long-term use can easily cause skin allergy, redness, itching and other discomfort symptoms. The present scheme coats the glue layer away from the air holes, so that the air permeability of the adhesive tape is better.

[0009] The longitudinal tear line and the base layer tear line are corrugated.

[0010] The longitudinal tear line and the base layer tear line are jagged.

[0011] The grid width a of the adhesive layer is 0.5-2mm, and the grid spacing b of the adhesive layer is 1-5mm.

[0012] The spacing c between the transverse tear lines is 3cm.

[0013] Further, the application tape is wound on a roller to facilitate storage of the application tape.

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

[0015] (1) By arranging the transverse tear line and the longitudinal tear line, the special parts of the human body are avoided, and the paste of the adhesive tape on the special parts is avoided, and the paste effect of the adhesive tape on different parts of the wound is better;

[0016] (2) By the deformation of the corrugated or jagged shape, the adhesion of the adhesive tape to the curved affected area is more fitted, and the use is safer and more reliable;

[0017] (3) By avoiding the arrangement of the air permeable hole through the coating of the adhesive layer, the air permeability of the affected area is better, the symptoms such as skin allergy, redness, itching and other discomfort are reduced, and the rehabilitation of the affected area is more beneficial.

[0023] In order to more clearly illustrate the technical features of the present scheme, the present scheme will be described below through a specific embodiment.

[0024] Embodiment one: see Figures 1-3A novel medical dressing tape includes a base layer 3, an adhesive layer 2 adhered to one side of the base layer 3, and a release paper 1 that can be separated and adhered to the other side of the adhesive layer 2. The release paper 1 is provided with a plurality of transverse tear lines 11 and longitudinal tear lines 12, and the base layer 3 is provided with a base layer tear line 31 corresponding to the longitudinal tear line 12.

[0025] More specifically, the base layer 3 is made of polyurethane film, and the adhesive layer 2 is made of acrylic adhesive.

[0026] A number of ventilation holes 32 are arrayed on the base layer 3, and the adhesive layer 2 is coated on the base layer 3 in a grid pattern, and the adhesive layer 2 is set away from the ventilation holes 32.

[0027] Existing medical tapes have poor breathability, which can easily lead to skin allergies, redness, itching and other discomfort after prolonged use. This solution improves the breathability of the tape by coating the adhesive layer 2 around the pores 32.

[0028] Furthermore, the adhesive layer 2 is coated on the base layer 3 in a rectangular grid pattern, and a number of vent holes 32 are arranged in a rectangular array on the base layer 3.

[0029] Both longitudinal tear line 12 and base layer tear line 31 are corrugated.

[0030] Both longitudinal tear line 12 and base layer tear line 31 are serrated.

[0031] The grid width a of adhesive layer 2 is 0.5-2mm, and the grid spacing b of adhesive layer 2 is 1-5mm.

[0032] The spacing c between the transverse tear lines 11 is 3cm.

[0033] Furthermore, the adhesive tape is wound onto roller 4 to facilitate the storage of the adhesive tape.

[0034] The specific usage process of this utility model:

[0035] See Figure 3This is a schematic diagram illustrating the application of the tape on the head in this embodiment. Specifically, when the wound is on the top of the head, after treating the wound, the tape is unfolded and cut to a suitable length with scissors. An opening is cut for the ear area according to the desired adhesion position. Then, the side strips are peeled off through the base tear line 31. Finally, according to the hairline, the release paper 1 to be pasted on the side of the face is peeled off along the horizontal tear line 11 and the vertical tear line 12. The release paper 1 on the head is retained to prevent the adhesive layer 2 from sticking to the hair. After the tape is prepared, it is pasted onto the affected area, completing the application of the tape. Because the tape does not stick to the hair, when changing the dressing or checking the affected area, tearing off the tape will not pull on the hair, reducing the pain when tearing off the tape. The horizontal tear line 11 and the vertical tear line 12 avoid specific areas of the body, preventing the tape from sticking to those areas, making the tape more suitable for wounds in different locations.

[0036] Release paper, also known as silicone paper or anti-stick paper, is a material used to isolate sticky materials. Its main function is to prevent prepreg from sticking together and to protect it from contamination. Release paper is commonly used with sticky materials, especially in adhesive tapes and wet-process prepreg production, where it is placed on both sides of the prepreg to prevent adhesion. Release paper has wide applications in many industries. It is primarily used as a carrier for tapes or adhesive-backed products, and also has applications in the food and medical industries.

[0037] Example 2: See Figure 4 The diagram illustrates the application of the tape to the affected area at the joint. The tape is unrolled from the roller 4, and two strips are torn along the base tear line 31 and the transverse tear line 11. The tape is then cut to a length appropriate for the joint. The release paper 1 is peeled off, and the tape is applied to the affected area. Because the affected area is curved, the tape's corrugated or serrated deformation after application allows for a better adhesion and adhesion to the curved surface. The ventilation holes 32 improve breathability, reducing discomfort such as skin allergies, redness, and itching, thus promoting recovery.

[0038] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
