Technical Field

[0001] The utility model belongs to the technical field of medical adhesive tapes, and in particular relates to a medical butterfly-shaped conjoined double-sided adhesive tape. Background Art

[0002] Medical tape is a commonly used dressing in the medical industry, used to bandage wounds and secure catheters or instruments for protection and fixation. Medical tape can be used to secure various medical instruments and equipment, ensuring they are positioned correctly and prevent movement during surgery, ensuring accuracy and safety. It can also be used to secure dressings, such as gauze and Band-Aids, to prevent them from shifting on the skin, ensuring dry wounds and safe healing.

[0003] During daily use, when the tape is fixed on the user's body surface, due to the user's activities, a single strip of tape is easy to loosen, affecting the fixing effect. In addition, during the application process, since the tape is relatively soft, it needs to be held and stretched from both ends at the same time to be flattened, which easily touches the colloid, causing the colloid to become dirty, which also affects the fixing effect. Utility Model Content

[0004] The purpose of the utility model is to provide a medical butterfly-shaped one-piece double-sided adhesive patch, aiming to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A double-sided adhesive tape body, comprising a base and a colloid layer coated on the sidewall of the base, wherein the base is a butterfly-shaped structure and the colloid layer is uniformly coated on the surface of the base;

[0008] Release paper, the inner side wall of the release paper is coated with an isolation layer, the lower side of the isolation layer is coated with a coating layer, the coating layer is adhered to the upper surface of the colloid layer, the upper end face of the release paper is adhered to a protective film, the middle of the protective film is integrally formed with a hollow protrusion, and the hollow protrusions are arranged at equal intervals on the surface of the protective film.

[0009] As a preferred solution of the present invention, the release paper has the same shape as the base, and a side strip structure matching the base is provided on the side wall of the release paper.

[0010] As a preferred solution of the present invention, the hollow protrusion is higher than the surface of the protective film, and a diaphragm is provided at the connection between the end of the hollow protrusion and the end of another group of the hollow protrusions.

[0011] As a preferred solution of the present invention, the thickness of the diaphragm is smaller than the thickness of the hollow protrusion, and the side wall of the hollow protrusion extends to the side wall of the diaphragm.

[0012] As a preferred solution of the present invention, a positioning block is provided at one side of the end of the base, the positioning block and the base are an integrally formed structure, and the base and the positioning block have the same thickness.

[0013] As a preferred solution of the present invention, a handle is integrally formed on the end of the release paper, the end of the handle extends to the side wall of the positioning block, and the protective film extends to the upper end of the handle.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The present application has better tensile strength by setting a butterfly-shaped base, effectively preventing the side wall from warping, maintaining a fixed state, and avoiding the tape from breaking. The colloid layer is used to adhere the base to the user's body surface to prevent the base from loosening;

[0016] The present invention adds a protective film with hollow protrusions on the other side of the release paper. The protective film is used to protect the release paper, prevent the release paper from being contaminated and scratched, enhance the durability and waterproofness of the release paper, improve the appearance and texture, and facilitate cleaning of the release paper.

[0017] The present application increases the strength of the protective film by adding a hollow protrusion in the middle of the protective film, thereby preventing the release paper from being easily deformed. When the release paper is bent, the side walls of the release paper will bend along the connection of the hollow protrusion with the cooperation of the protective film. When it needs to be flattened for use, a certain force is applied inward to press the hollow protrusion so that the hollow protrusions are connected to each other to form a long strip of protrusion structure, which can cooperate with the release paper to maintain the substrate in a relatively flat state, making it convenient to apply to the use area without stretching the tape over a large area, thereby reducing the possibility of dirt caused by hand-held contact with the colloid.

A hollow protrusion 204 is integrally formed in the middle of the protective film 203, and the hollow protrusions 204 are arranged at equal intervals on the surface of the protective film 203.

[0031] Among them, the butterfly-shaped base 101 has better tensile strength, effectively prevents the side wall from warping, maintains a fixed state, and avoids the tape from breaking. The colloid layer 102 is used to adhere the base 101 to the user's body surface to prevent the base 101 from loosening. A release paper 200 with a coating layer 202 is added to the surface of the base 101. The coating layer 202 can prevent the colloid layer 102 from adhering to the surface of other objects and prevent the colloid layer 102 from being dirty. At the same time, an isolation layer 201 is added between the coating layer 202 and the release paper 200 to prevent the coating of the coating layer 202 from penetrating into the interior of the release paper 200. Isolation layers 201 of different materials can be added as needed. For example, silicone resin coatings have good peeling properties and heat resistance, while polypropylene coatings have higher gloss. A hollow protrusion is added on the other side of the release paper 200. The protective film 203 of 204 is used to protect the release paper 200, prevent the release paper 200 from being contaminated and scratched, enhance the durability and waterproofness of the release paper 200, improve the appearance and texture, and also facilitate the cleaning of the release paper 200. Adding a hollow protrusion 204 in the middle of the protective film 203 can improve the strength of the protective film 203 and prevent the release paper 200 from being easily deformed. When the release paper 200 is bent, the side wall of the release paper 200 will bend along the connection of the hollow protrusion 204 with the cooperation of the protective film 203. When it needs to be flattened for use, a certain force is applied inward to press the hollow protrusion 204, so that the hollow protrusions 204 are connected to each other to form a long strip of protrusion structure, which can cooperate with the release paper 200 to maintain the substrate 101 in a relatively flat state, making it convenient to apply to the use area.

[0032] Specifically, the release paper 200 has the same shape as the base 101 , and a side strip structure matching the base 101 is provided on the sidewall of the release paper 200 .

[0033] Furthermore, the hollow protrusions 204 are higher than the surface of the protective film 203 , and a diaphragm 205 is provided at the connection between the end of the hollow protrusion 204 and the end of another group of hollow protrusions 204 .

[0034] Furthermore, the thickness of the diaphragm 205 is smaller than the thickness of the hollow protrusion 204 , and the sidewall of the hollow protrusion 204 extends to the sidewall of the diaphragm 205 .

[0035] Preferably, a positioning block 103 is provided at one end of the base 101 . The positioning block 103 and the base 101 are integrally formed. The base 101 and the positioning block 103 have the same thickness.

[0036] The positioning block 103 is added to facilitate holding the positioning block 103 to fix the tape at the position where it needs to be applied, and also facilitate fixing the base 101 and removing the release paper 200 from the surface of the base 101 .

[0037] Preferably, a handle 206 is integrally formed at the end of the release paper 200 , the end of the handle 206 extends to the side wall of the positioning block 103 , and the protective film 203 extends to the upper end of the handle 206 .

[0038] A handle 206 is added to the side wall of the release paper 200 to facilitate peeling off the release paper 200 from the surface of the base 101 to meet different usage requirements.

[0039] In summary, the butterfly-shaped base 101 has better tensile strength, effectively prevents the side wall from warping, maintains a fixed state, and avoids the tape from breaking. The colloid layer 102 is used to adhere the base 101 to the user's body surface to prevent the base 101 from loosening. A release paper 200 with a coating layer 202 is added. The coating layer 202 can prevent the colloid layer 102 from adhering to the surface of other objects and prevent the colloid layer 102 from getting dirty. At the same time, an isolation layer 201 is added between the coating layer 202 and the release paper 200 to prevent the coating of the coating layer 202 from penetrating into the interior of the release paper 200. Isolation layers 201 of different materials can be added as needed. For example, silicone resin coatings have good peeling properties and heat resistance, while polypropylene coatings have higher gloss. A hollow protrusion 204 is added on the other side of the release paper 200. The protective film 203 is used to protect the release paper 200, prevent the release paper 200 from being contaminated and scratched, enhance the durability and waterproofness of the release paper 200, improve the appearance and texture, and also facilitate the cleaning of the release paper 200. Adding a hollow protrusion 204 in the middle of the protective film 203 can improve the strength of the protective film 203 and prevent the release paper 200 from being easily deformed. When the release paper 200 is bent, the side wall of the release paper 200 will bend along the connection of the hollow protrusion 204 with the cooperation of the protective film 203. When it needs to be flattened for use, a certain force is applied inward to press the hollow protrusion 204, so that the hollow protrusions 204 are connected to each other to form a long strip of protrusion structure, which can cooperate with the release paper 200 to maintain the substrate 101 in a relatively flat state, making it convenient to apply to the use area.
