Collagen Wound Dressing

100% bovine collagen supports wound healing and has favorable tissue affinity and excellent biocompatibility.

 

A porous matrix of cross-linked bovine collagen makes up LUOFUCON® Collagen Wound Dressing. The LUOFUCON® Collagen Wound Dressing is a sterile, single-use wound dressing that is white or off-white, malleable, absorbent, and biodegradable.

When the wound dressing absorbs wound exudate or sterile water, LUOFUCON® Collagen Wound Dressing transforms into a soft, conformable gel sheet, maintains a moist wound environment, to protect the wound and support natural healing.

LUOFUCON® Collagen Wound Dressing may be applied directly to the wound as a primary dressing or may be used in conjunction with other acceptable secondary dressings. The dressing may be used in numerous layers and can be precisely trimmed to fit the size of the wound.

What is the collagen ?

Collagen is the unique, triple helix protein molecule, which forms the major part of the extracellular dermal matrix (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. Mainly produced by fibroblasts, at least 29 genetically distinct collagens have currently been identified, with six of these being present in the skin. Collagen type I comprises approximately 90% of collagen in the skin. Type I and III 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 as fibroblasts 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 to elevated levels of matrix metalloproteinases (MMPs) in the wound. In normal wound healing, proteases such as MMPs are attracted to the wound during the inflammatory phase and have an important role in breaking down unhealthy ECM so that new tissue forms. However, when MMPs are present in a wound at elevated levels for a prolonged period of time, this results in the 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 reduce protease levels in the wound. This suggests a role for dressings containing collagen in the management of wounds where healing is stalled.

Collagen dressings in wound management

The use of collagen dressings may seem attractive in view of their functions to:

  • Inhibit or deactivate MMPs
  • Aid in the uptake and bioavailability of fibronectin
  • Help to preserve leukocytes, macrophages, fibroblasts, and epithelial cells
  • Assist in the maintenance of the chemical and thermostatic microenvironment of the wound

Advantages about LUOFUCON® Collagen Wound Dressing

  • The dressing, which falls under the category of permanent contact device, is non-pyrogenic, super conformance, entirely absorbable, and simple to use. 
  • Dressings are suitable for use under compression under proper supervision by a healthcare professional.
  • It serves as a porous scaffold for cell proliferation and migration and may be used as a hemostatic dressing for surface wounds.
  • The product’s strength and enzyme resistance are increased without the use of chemical additives and with the aid of safe cross-linking technology.
  • Excellent technical level and integrity of structure.

Indications

LUOFUCON® Collagen Wound Dressingis intended for the management of wounds including: 

  • Full thickness and partial thickness wounds
  • Pressure ulcers
  • Venous ulcers
  • Ulcers caused by mixed vascular etiologies
  • Diabetic ulcers
  • Partial thickness burns
  • Donor sites and other bleeding surface wounds
  • Abrasions
  • Traumatic wounds healing by secondary intention
  • Dehisced surgical incisions

 

Contraindications

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

Tips for using Collagen Wound Dressing

  • Do not use with uncontrolled clinical infection.
  • Do not use if the package seal is broken.
  • Do not use dressing after expiration date.
  • Discard device if mishandling has caused possible damage or contamination.
  • Discard all open and unused portions of dressing.
  • Do not re-sterilize. 
  • Do not reuse.
  • Discontinue use and contact a physician if any adverse reactions and abnormal symptoms occur.
