Description

Technical Field

[0001] This application relates to the technical field of seamless tapes, and more specifically, to a breathable seamless tape. Background Art

[0002] As a kind of draw tape that can be used to fix wounds, the seamless tape is suitable for the draw fixation and wound repair on the surface of wounds or incisions, can be directly used for the closure of small skin wounds or incisions, and avoids the pain of the injured when suturing the wound.

[0003] Some existing seamless tapes are usually made by compound die-cutting non-woven fabric, pressure-sensitive adhesive, and release film. The non-woven fabric and pressure-sensitive adhesive provide the tensile strength and adhesive strength of the seamless tape. However, due to the poor air permeability of the glue layer, although it provides adhesive strength after being compounded with the non-woven fabric, it will affect the air permeability of the base material. During use, the moisture and sweat on the skin are not easy to evaporate, resulting in a decrease in the adhesive performance of the tape or even falling off, and long-term use is likely to cause wound or incision infection and inflammation.

[0004] To solve the above problems, this application provides a breathable seamless tape. Utility Model Content

[0005] The breathable seamless tape provided by this application adopts the following technical solutions:

[0006] A breathable seamless tape includes a non-woven fabric. An acrylate layer is provided at the bottom end of the non-woven fabric. A release layer is provided below the acrylate layer, and the top end of the release layer is connected to the acrylate layer through a pressure-sensitive adhesive. Dry tapes are provided on both the left and right sides of the top end of the non-woven fabric, and the dry tapes are fixedly connected to both the non-woven fabric and the acrylate layer.

[0007] Through the above technical solutions, the use of a highly breathable acrylic resin material improves air permeability, and at the same time, polyester filaments are used to form a gas exchange channel to further improve air permeability.

[0008] Further, release papers are provided at the top ends of the dry tapes, and the release papers are movably attached to the top ends of the dry tapes.

[0009] Through the above technical solutions, it is convenient to shield and protect the dry tapes when not in use.

[0010] Further, the acrylate layer and the non-woven fabric are adhered into an integral composite structure, and the acrylate layer plays an effect of enhancing the tensile strength of the tape.

[0011] Through the above technical solutions, it is convenient for the seamless tape to be used for a long time during use.

[0012] Further, the non-woven fabric is made of polypropylene, polyester, and polyamide materials, and the gram weight of the non-woven fabric is between 10 grams and 50 grams per square meter.

[0013] Through the above technical solution, the softness and air permeability of the non-woven fabric are prevented from being affected.

[0014] Further, the pressure-sensitive adhesive is a pressure-sensitive adhesive made of polyacrylate material, and a hot-melt medical pressure-sensitive adhesive can also be used.

[0015] Through the above technical solution, it is convenient to provide the bonding strength and tackiness required for the sutureless tape during use, and at the same time, it also has good waterproof, moisture-permeable, and antibacterial effects.

[0016] Further, the release layer is made of release paper or release film. The release paper is made of Graffix release paper, CKK, or PET, and the gram weight per square meter is between 40 grams and 120 grams. The release film is made of PET release film or PE release film, and the thickness of the film material is between 15 microns and 50 microns.

[0017] Through the above technical solution, it is mainly used for the covering and protection of the pressure-sensitive adhesive layer.

[0018] In summary, the present application includes the following beneficial technical effects:

[0019] The non-woven fabric and the acrylate layer adopted have good air permeability, which can ensure the breathing of the wound and the surrounding normal skin, will not macerate the skin and affect the adhesiveness of the tape, have good comfort, are easy to use, have obvious effects, can replace the doctor's suture treatment of surgical incisions, reduce the pain of patients, and improve the strength of the non-woven fabric with acrylate, replacing imported non-woven fabric and reducing the product cost.
