Sticking structure

The present invention relates to a covering structure, in particular to a covering structure which is transparent, easily observes the change and healing of the wound, and provides a high moisture permeability and a comfortable feeling for the wound.

According to recent scientific and statistical reports, the global trauma market is growing in demand, especially in surgical trauma, and its total number has exceeded 100 million person-times per year, and it is increasing year by year. Because of the trauma and laceration caused by accidents, about 20 million person-times per year, the number of burns and burns is about 10 million person-times per year; the ulcerative wounds caused by chronic diseases, diabetes and population aging have exceeded 3 Tens of thousands of people every year.

Surgery because of the need for treatment and the popularity of endoscopic surgery, has greatly reduced the risk of surgery, but it is followed by the need for better wound care and post-surgical scar prevention. Various advanced applicator structures for wound care to shorten wound healing time while eliminating scarring.

The traditional applicator structure is composed of natural plant fibers or animal hair materials, such as gauze, cotton pad, wool, various types of oil gauze, etc. These applicator structures are only temporary covering materials, all of which need to be in a certain period of time. Replace it. However, these wound covering structures are prone to sticking to the wound when they are replaced, so it is possible to tear open the new structure while tearing off the covering structure. Raw epithelial cells or wounds that have gradually healed cause the user to suffer from pain and are quite detrimental to the natural healing of the wound.

The research on the existing applicator structure has made people's understanding of the applicator structure more and more scientific. The research shows that the better applicator structure can maintain the good cell growth and healing environment at the wound site, and can control and absorb the exudate; breathable, moisture permeable, energy Prevent bacterial invasion; can be applied to individuals; can be loaded and released; should have good tissue and blood compatibility, no adhesion and desquamation when removed from individuals; should also have better Mechanical properties and tensile strength, easy to use.

Compared with the traditional applicator structure, the hydrogel applicator structure can provide better ventilation, moisture permeability, barrier of bacterial invasion and control and absorption of exudate, so that the wound is in a good cell growth healing environment. In addition, the hydrogel overlay structure can be closely attached to the wound, and the wound does not stick to the wound to cause secondary damage when the patch structure is replaced. Therefore, the hydrogel patch structure is widely used in the field of biomedicine.

Generally, the support layer of the conventional laminated structure product is made of a material that is not easily stretched, such as polyethylene (PE), polypropylene (PP), or nylon (Nylon), and is combined with a hydrogel to form a covering structure. In the case of products, because the support layer cannot be effectively stretched, the attachment structure is easily broken and the structure or product is unable to conform to the user's body. The lack of compliance with the user's body generally causes the hydrogel-attached structure product to be absent. The comfort and service that the user wants. In addition, the lack of compliance with the user's body generally results in the inability of the hydrogel-attached product to perform effective liquid absorption, distribution, and maintenance. Another problem derived from the lack of ease of stretching of the hydrogel-attached structure is that the hydrogel-attached structure may be disintegrated into the material of each isolated area or mass, causing discomfort to the user and reducing hydrogel coverage. The efficiency of the structure.

German researchers have recently invented a bandage that turns purple in the early stages of wound infection. The new dressing used in this bandage developed by the Munik Institute of Solid State Research in Germany contains a special dye that reacts to different pH levels. This new type of traumatic bandage can be used to isolate wounds like other bandages, but the new product offers a special way to observe wound healing. Under normal circumstances, healthy skin and healing wounds are weakly alkaline, with a pH of about 5-6. If the pH is elevated and alkaline, it may indicate an infection. If the pH is between 6.5 and 8.5, the new bandage will turn purple. The color-changing bandage is convenient for patients and doctors to monitor the infection without changing the dressing. Because the bacteria will take advantage of the bandage when the bandage is removed.

At present, the scientific community and dermatologists know that the best pH value in the wound healing process should be weakly acidic, which can inhibit the growth of bacteria, shorten the inflammatory phase of wounds, and promote the regeneration of blood vessels and epithelial tissues, shortening the healing time of wounds. . The Joanneum Institute of Austria's Styrian State announced that the successful development of a new generation of medical supplies "Wattestäbchen" can detect the ph-pH of the skin surface while cleaning the wound, helping medical personnel to master healing and Restore progress and improve medical results. The cotton stick developed by Joanneum is similar to a “traffic light”. Because of a special stain, when the wound is treated with the cotton swab or cotton swab, if the skin is weakly acidic, it will be displayed in light green (green light). When the skin of the wound is alkaline, a red "warning" will appear to remind the injured or nursing staff to clean and change the dressing in time, which can save the time required for additional sampling and testing, and effectively improve the medical effect.

A long-felt need in the art is to create a hydrogel overlay that excels in the performance characteristics of commonly known hydrogel overlay structures. More specifically, it is also desirable to produce a hydrogel overlay structure that is stretchable and conforms to the user's body, and the hydrogel overlay structure is generally used. The change and healing of the wound can be easily observed at any time, and the wound can provide high moisture permeability and comfort.

Therefore, after testing by multiple parties, the creator found that adjusting the hydrogel overlay structure can improve the above problems. Therefore, the present invention provides a covering structure which can easily observe the change and healing condition of the wound at any time in general use, and provides a high moisture permeability and a comfortable feeling for the wound, including: a backing layer, which is composed of a a film layer and a support layer having pores are attached to each other; and a glue layer is bonded to the support layer having pores, and a part of the glue layer penetrates the pore, wherein the back layer and the glue layer are closely adhered to each other A transparent covering structure.
