Description

Wound and catheter infusion wound protection device The present application claims priority to Chinese patent application filed on December 7, 2011, Chinese Patent Office, application number 201120506203.X, entitled "Chongkou, catheter infusion wound protection device" The entire contents of which are incorporated herein by reference. Technical field

The invention relates to the technical field of medical auxiliary equipment, in particular to a wound and catheter infusion wound protection device.

Background technique

With the rapid development of medical technology in the world today, the clinical use of dressings for the wound and medical puncture catheter infusion wound care technology has also greatly developed, from the traditional yarn cotton dressing, tape fixed development to the current transparent film dressing , foam materials, hydrocolloid dressings and functional dressings, etc., these dressings have strong absorption, some transparent, good compliance, waterproof and antibacterial. However, most of these techniques require the pads or mats in the dressing to mechanically coat the wound and are secured by a fixed layer of adhesive layer to bond the pads, the mat and the skin. These pads or mats can be different. Functional dressing materials are manufactured, such as water-retaining pads, non-stick pads, antibacterial pads, and the like. In the care protection of catheter infusion wounds, some treatments are to use a transparent application without a pad, directly bonded to the medical puncture catheter through the adhesive layer provided on the wound and the catheter, and bonded The catheter is fixed to the skin. Although the treatment method is transparent, easy to observe, and enables the relevant personnel to handle it in time, the adhesive is easy to cause wounds and skin allergies, contact dermatitis such as flushing, swelling, itching, eczema. An inflammatory reaction such as vesicles can cause complications of blood infection in severe cases. Other treatments are: use a transparent or opaque applicator with a pad or mat, although these are avoided by direct contact between the adhesive and the skin surrounding the wound, but these dressings will The wound secretion containing the necrotic tissue is adhered to the pad or the village mat. When the dressing is replaced or removed, the wound is damaged again, the healing is delayed, and it is not convenient to observe the treatment in time because of opacity. At present, with the development of technology, there are also some anti-tissue dressings or "non-contact" wound care devices, such as "cover", "frame" and other wound care technologies, but these anti-tissue adhesion materials can not completely prevent adhesion and The tissue repels the inflammatory response to foreign bodies, and these "hood" or "frame" wound care devices are directly bonded to the skin through the bottom, lacking effective fixation, difficult to stabilize, easy to move and collapse, and cause wound re-destruction, delay It can not be applied to the central venous catheter, the peripheral venous catheter, the fixation of the intravenous indwelling needle catheter, and the care of the catheter infusion wound, and it is also complicated in manufacturing and application, so it is difficult to promote it in clinical practice.

In clinical practice, patients with intensive care and long-term chemotherapy, as well as patients requiring long-term intravenous nutritional support, require central venous catheters, peripheral venous catheters, and intravenous indwelling needle catheters for treatment. All must be covered with a dressing. Infusion of the wound and fixation of these catheters, so the care of the infusion wound and the fixation of the infusion catheter are effective and reasonable to avoid serious complications such as venous inflammation and blood infection caused by wound infection, which will affect the overall treatment effect and the patient. An important factor in the healing situation, in order to avoid the occurrence of these complications, early clinically thoroughly disinfected before infusion, and then covered with ordinary tape and dressing, this traditional method can not always observe whether the infusion has infection changes, At the same time, the ordinary adhesive tape is poorly applied, and it is difficult to effectively fix the catheters protruding on the skin surface. Therefore, it is more common to use a transparent film dressing to cover and paste for care and fixation, and the advantages are transparent visibility and good adhesion, but due to Remove the pad for visibility, Monolithic dressings became a completely transparent film, the adhesive layer of the sensitized against the infusion port and the convex surface of the conduit and then adhered to the surface of the skin, clinically proven, using The application method of transparent film causes the accumulation of sweat between the skin surface and the transparent film to promote the growth of bacteria. These factors are easy to cause inflammation of the wound infusion, and there is a risk of serious complications such as blood infection, so it is often necessary Frequent changes to dressings and even infusion sites increase patient suffering and medical costs.

In addition, when it is clinically necessary to re-disinfect and debride a wound or a catheter for re-sterilization and debridement, the dressing must be replaced as a whole, which increases the medical burden on the patient.

In addition to the above-mentioned defects, the existing protective nursing techniques and methods for wounds cannot prevent wound tearing and cracking caused by external force or tension. Currently, the wounds and tears should be clinically dealt with. There is no effective method and technique, especially for surgical wounds and traumatic wounds located in the abdomen and joints. It is caused by coughing, postoperative abdominal distension, forced bowel movements, joint movement, etc., causing tears and cracks. Heal and cause complications such as infection.

Therefore, it is necessary to improve wounds, catheter infusion wound care and protective treatment techniques to meet the following needs;

1. The improved wound protection device can effectively prevent tearing and cracking of wounds (including surgical suture wounds, traumatic wounds, catheter infusion wounds and some high-tension wounds), avoiding wound skin movement wrinkles and wound damage and wounds Wound damage caused by relative movement friction with the dressing.

Second, the improved wound protection device is transparent and prevents the adhesive from directly bonding the wound, the skin around the wound and the surface of the catheter adjacent to the wound.

Third, the improved wound protection device is transparent and visible, and does not directly contact and compress the wound. Fourth, the improved wound protection device can easily disinfect, debride, drain, and use anti-infective and wound-healing-resistant drugs at any time without the need for the entire replacement. 5. The improved wound protection device is convenient to keep the wound moist and to keep the wound dry.

Sixth, the improved wound protection device does not need to be replaced frequently, reducing medical costs.

7. The improved wound protection device can be waterproof and breathable, and is convenient for patients' daily life. Summary of the invention
