[0043] Working principle:
[0044] When using the special patch for central venous catheter for reducing skin lesions, first, sufficient preparation work is needed. Check the patch package for integrity, no contamination or damage, ensure the quality and safety of the patch. Secondly, carefully clean and dry the skin area where the patch needs to be attached. Use a mild cleanser and soft cloth to gently wipe the skin, remove oil, dirt and sweat, then let the skin dry naturally or gently pat dry with a clean towel, so that the patch can be tightly attached to the skin and not easily fall off.
[0045] When the skin is carefully cleaned and dried, the application stage of the patch is entered. The label paper 4 records the medical information, and the label paper 4 is torn off by tearing the raised structure 41 of the label paper. First, the bottom layer of the release paper 3 is carefully torn off, and the bottom layer of the release paper 3 is an indispensable part of the patch structure. The design is used to protect the transparent patch layer 2 and the adhesive surface of the annular foam dressing 21, effectively isolate dust and bacteria from the outside world, and ensure that the patch maintains a sterile state before use. After the release paper layer is slowly removed, the transparent patch layer 2 with the annular foam dressing 21 is gently and tightly attached to the skin, and the annular foam dressing 21 is in contact with the skin. A certain gap is easy to tear off the patch. At this time, the patch hand tear ring layer 1 not only provides necessary support when the patch is used, but also ensures that the patch can remain flat and wrinkle-free during the process of attaching to the skin, and is not easy to fall off, giving the user long-term peace of mind and comfort.
[0046] After the patch is fixed, the next step is to tear off the patch hand tear ring layer 1. Find the tear point along the hand tear notch 11 or the patch opening 12, and the right side of the hand tear notch 11 is provided with a protrusion for identifying the tear direction. The design facilitates easy tearing of the patch hand tear ring layer 1 when tearing. Slowly tear off the patch hand tear ring layer 1, and due to the design of the hand tear notch and the patch opening, the patch hand tear ring layer 1 can be easily torn off without causing additional pressure or damage to the skin.
[0047] When the patch is used up, it needs to be removed. At this time, the transparent patch layer 2 is gently torn off along the edge of the annular foam dressing 21. The annular foam dressing 21 does not affect the adhesion of the patch to the skin and the tightness when the skin is attached, and the gap left when the annular foam dressing 21 contacts the skin also makes the patch easier to remove. The design makes the patch not cause too much pulling force on the skin when it is torn off, thereby reducing the pain caused by tearing off the patch.
[0048] The above describes the present application by means of specific embodiments, but it should be understood that the specific description herein should not be construed as limiting the essence and scope of the present application. Various modifications made by those skilled in the art after reading the specification belong to the scope of the present application.
