Description

a covering structure

technical field

The utility model relates to a sticking structure, in particular to a transparent sticking structure which can easily observe the change and healing state of the wound, and at the same time can provide higher moisture permeability and comfort to the wound.

Background technique

According to scientific and statistical reports in recent years, the demand for the global trauma market is increasing, especially for surgical trauma, the total number of which has exceeded 100 million per year, and is increasing year by year. The number of wounds and lacerations caused by accidents is about 20 million people per year, and the number of burns and scalds is about 10 million people per year; ulcer wounds caused by chronic diseases, diabetes, and population aging have exceeded 30 million people per year. Millions of people every year.

Because of the need for treatment and the popularity of endoscopic surgery, the risks posed by surgery have been greatly reduced, but with it comes the need for better wound care and postoperative scar prevention. Various advanced overlay structures for wound care methods to shorten wound healing time and eliminate scarring.

The traditional covering structure is composed of natural plant fibers or animal hair materials, such as gauze, cotton pad, wool, all kinds of oil gauze, etc. This type of covering structure is only a temporary covering material, which needs to be covered within a certain period of time. be replaced. However, these wound covering structures are prone to adhesion to the wound when they are replaced. Therefore, when the covering structure is torn off, new epithelial cells or gradually healed wounds may be torn apart, causing unbearable pain to the user. , and is not conducive to the natural recovery of wounds.

The research on the existing sticking structure has made people's understanding of the sticking structure more and more scientific. The research shows that: a better sticking structure can maintain a good environment for cell growth and healing at the wound, and can control and absorb exudates; breathable and moisture-permeable. It can prevent bacteria from invading; it can be closely attached to the individual; it can carry and release drugs; in addition, it should have good tissue and blood compatibility, and no adhesion and desquamation will occur when it is removed from the individual; it should also have better Excellent mechanical properties and tensile strength, easy to use.

Compared with the traditional sticking structure, the hydrogel sticking structure can provide better characteristics such as air permeability, moisture permeability, blocking bacterial invasion, and controlling and absorbing exudate, so that the wound is in a good environment for cell growth and healing. In addition, the hydrogel sticking structure can be closely attached to the wound, and will not adhere to the wound and cause secondary damage when replacing the sticking structure, so the hydrogel sticking structure is widely used in the field of biomedicine.

Generally, the support layer of the traditional sticking structure product is made of non-extensible material such as polyethylene (Polyethylene, PE), polypropylene (Polypropylene, PP) or nylon (Nylon), which is combined with hydrogel to form a sticking structure. When the product is used, the support layer cannot be effectively stretched, which easily causes the covering structure to break and makes the structure or product unable to conform to the user's body. The comfort and fit the user wants. In addition, the lack of compliance to the user's body generally results in the ineffective liquid absorption, distribution and retention of hydrogel overlay products. Another problem derived from the lack of easy stretching of the hydrogel covering structure is that the hydrogel covering structure may disintegrate into isolated areas or lumps of material, causing discomfort to users and reducing the hydrogel covering structure. s efficiency.

German researchers recently created a bandage that turns purple in the early stages of wound infection. The new dressing used in the bandage, developed by the Institute for Modular Solid State Research in Munich, Germany, contains a special dye that responds to different pH levels. This new type of externally invasive bandage can be used to insulate wounds like other bandages, but the new product provides a special way to observe wound healing. Under normal circumstances, healthy skin and healing wounds are weakly alkaline, with a pH of around 5 to 6. If the pH is elevated, towards alkaline, an infection may have occurred. If the pH is between 6.5 and 8.5, the new bandage will turn purple. Color-changing bandages allow patients and doctors to monitor infection without changing dressings, which is an advantage. Because bacteria can get in when the bandage is removed.

At present, the scientific community and dermatologists know that the optimal pH value in the wound healing process should be weakly acidic, which can inhibit the growth of bacteria, shorten the inflammatory period of the wound, and promote the regeneration of blood vessels and epithelial tissue, thereby shortening the wound healing time. The Joanneum Institute in Steyrbon, Austria announced that it has successfully developed a "cotton swab" for a new generation of medical products It can detect the pH value of the skin surface while cleaning the wound, which helps medical personnel to grasp the progress of healing and recovery and improve the medical effect. The cotton swab developed by Joanneum is similar to a "traffic light". Due to a special dye, 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 wound skin is alkaline, a red "warning signal" will appear, reminding the injured or nursing staff to clean and change the dressing in time, which can save the time that additional sampling and testing was required in the past, and effectively improve the medical effect.

There is a long-standing need in the art to produce a hydrogel coating structure that exceeds the performance characteristics of generally known hydrogel coating structures. More specifically, it is also desirable to produce a hydrogel covering structure that can stretch and conform to the user's body, and the hydrogel covering structure can easily observe the changes and healing status of the wound at any time during general use. , At the same time, it can provide high moisture permeability and comfort for wounds.
