What is the collagen ?
Collagen is the unique, triple helix protein molecule, which forms the major part of the extracellular dermal matrik (ECM).
together with the glycosaminoglycans, proteoglycans, laminin, fibronectin, elastin and cellular components.
Collagen is the most abundant protein in animal tissues and accounts for 80% -90% of the dry weight of the dermis. Mainlyproduced by fibroblasts,at least 29 genetically distinct collagens have currenty been identified, with six of these being presentin the skin. Collagen type I comprises approximately 90% of collagen in the skin. Type land ll are important for wound healing.
Role of collagen in wound healing
Collagen plays an important role in each of these phases of wound healing due to its chemotactic role. It attracts cells such asfibroblasts and keratinocytes to the wound. This encourages angiogenesis and reepithelialisation.
A chronic wound is stalled at one of these healing stages. This usually occurs during the inflammatory phase and is linked toelevated levels of matrix metalloproteinases (MMPs) in the wound. In normal wound healing. proteases such as MMPs areattracted to the wound during the inflammatory phase and have an important role in breaking down unhealthy ECM so thatnew tissue forms. However, when MMPs are present in a wound at elevated levels for a prolonged period of time, this results inthe destruction of healthy ECM, which is associated with delayed wound healing and an increase in wound size.
When the excess of MMPs is not balanced by normal physiological processes, alternative methods are required to reduceprotease levels in the wound. This suggests a role for dressings containing collagen in the management of wounds wherehealing is stalled.

Instructions for use
|
1. Remove device from pouch and cut the dressing to better match the wound area with standard aseptic/sterile technique.
2. Apply the dressing directly to the wound bed, and rehydrate the dressing with sterile water or saline if the wound bed is dry.
3. Based on the wound type, the wound may be covered with a suitable secondary dressing.
4. Discard any unused portion of the device.

Precautions |
Patients who are sensitive to bovine collagen, those with third-degree burns, or wounds that are infected actively should not use collagen wound dressing. |
