[0041] Allergen antigen added layer 2, used to reduce the chance of triggering an allergic reaction when in contact with the skin;

[0042] The elastic layer 3 is used to increase the elasticity of the medical tape so as to conform to the curves of the human body;

[0043] A silicone adhesive layer 4, used to provide adhesion and reduce irritation and allergic reactions to the skin;

[0044] A plurality of acrylic adhesive layers 5, used to enhance the adhesion between the edge of the medical tape and the skin;

[0045] The anti-adhesive layer 6 is used to protect the silicone adhesive layer 4 and the acrylic adhesive layer 5 from external pollution and facilitate peeling before use.

[0046] Through the cooperation between the silicone adhesive layer 4 and the acrylic adhesive layer 5, the acrylic adhesive layer 5 intermittently distributed on the edge of the tape can effectively strengthen the firmness of the edge of the medical tape, avoid the edge warping of the tape after long-term use, improve the overall adhesion of the tape, avoid the tape from falling off, and achieve the purpose of effectively fixing the wound for a long time.

[0047] like Figure 3A second embodiment is shown, which mainly differs from the first embodiment in that: an anti-allergic medical tape, an allergen antigen added layer 2 is arranged on the top of a polypropylene film layer 1, an elastic layer 3 is arranged on the top of the allergen antigen added layer 2, a plurality of acrylic adhesive layers 5 are evenly arranged on the front and rear ends of the top of the elastic layer 3, a silicone adhesive layer 4 is arranged between the top of the elastic layer 3 and the plurality of acrylic adhesive layers 5, and an anti-sticking layer 6 is arranged on the bottom of the polypropylene film layer 1.

[0048] By setting the allergen antigen adding layer 2, the allergens can be effectively prevented from directly contacting the skin, reducing the risk of allergic reactions in patients. When the anti-allergic medical tape is attached to the skin, the elastic layer 3 can make the tape fit the curve and contour of the skin tightly, thereby reducing the gap between the tape and the skin, avoiding local blistering or cracks, making it more in line with the curve of the human body, and improving the wearing comfort of the tape.

[0049] The embodiment of the present invention also provides a method for preparing an anti-allergic medical tape, which is used for the anti-allergic medical tape. The specific method includes the following steps:

[0052] Step 3: preparing the allergen antigen added layer 2: coating the allergen antigen added layer 2 material on the upper surface of the polypropylene film layer 1, ensuring that the coating is uniform and of moderate thickness during the coating process, ensuring that the added allergen antigens are evenly distributed on the surface of the polypropylene film layer 1, and performing a curing treatment, using a baking device to perform baking and curing, so that the allergen antigen added layer 2 is fully bonded to the polypropylene film layer 1 after curing;

[0053] Step 4, preparing the elastic layer 3: coating the elastic layer 3 material on the surface of the allergen antigen added layer 2, ensuring that the coating is uniform and the thickness is uniform during the coating process, ensuring that the elastic layer 3 is evenly attached to the allergen antigen added layer 2, and performing a curing treatment, using a baking device to bake and cure, so that the elastic layer 3 is firmly attached to the allergen antigen added layer 2 after curing;

[0054] Step 5, preparing an acrylic adhesive layer 5: applying the acrylic adhesive once at intervals of 0.5 cm on the front and rear ends of the surface of the elastic layer 3, ensuring uniform coating to avoid missing coating or excessive coating. After coating the acrylic adhesive, put it into a preheated drying machine and immediately perform heat curing treatment for 5 minutes to allow the acrylic adhesive to dry and cure;

[0055] Step 6, preparing the silicone adhesive layer 4: coating the silicone adhesive on the surface of the elastic layer 3, using a roller to operate during the coating process to ensure uniform coating and clear edges, and after coating the silicone adhesive, heat curing for 10 minutes to dry and cure the silicone adhesive;
