Clinical-Grade Irradiated Biological Dressing for Wound Repair & Scar Reduction

1. Product name

2. Product Overview

Key Features:

• Clean, soft, non-toxic, sterile, and non-irritating
• Porcine skin with high permeability and adhesion
• Eliminates antigenicity via irradiation technology, avoiding 
• Added sulfadiazine zinc to enhance anti-infection properties
• 

3. Purpose

• Relieve pain
• Prevent bacterial infection
• Reduce the loss of water, electrolytes, body fluids, and proteins
• Promote epithelial growth and accelerate wound healing
• Minimize scarring, reduce dressing changes, and alleviate patient pain

4. Clinical Advantages

1. Rapid healing: Significantly shortens healing time for deep partial-thickness wounds, lowering infection risk and shortening hospital stays.
2. Reduced dressing changes: Ideal for patients who fear dressing changes, minimizing pain and discomfort.
3. Donor site conservation: Effective for large-area burn patients with limited skin donors, covering wounds temporarily.
4. Important note: Promptly remove liquefied dressings and perform routine wound dressing changes.

5. Instructions for Use

Five Clinical Application Methods:

1. For deep and superficial partial-thickness mixed burn wounds:

    

   After routine irrigation and disinfection, remove loose/peeled blister skin. Apply the pre-thawed dressing closely to the wound, cover with sterile dressings, and apply pressure bandaging. Puncture the elastic bandage with holes for ventilation. Change the outer dressing every 3–5 days. When the bandage feels "empty" to the touch, the wound has healed; soak the dressing to facilitate removal.
    
2. For deep partial-thickness and full-thickness wounds:

    

   After two weeks of dressing application, the surrounding wound heals and shrinks. The dressing’s debridement action promotes granulation tissue formation in full-thickness wounds, preparing them for subsequent skin grafting repair.
    
3. For covering stumps, skin donor sites:

    

   Apply pressure bandaging after application to protect the wound.
    
4. For covering non-functional deep partial-thickness post-excision wounds:

    

   Promotes primary healing of the wound.
    
5. For infected granulation wounds (50–70% area):

    

   Cut the irradiated biological dressing into 2×2cm postage stamp-sized pieces. Mix with 0.5×0.5cm autologous split-thickness skin grafts at ratios of 2:1, 3:1, or 4:1 for one-stage mixed transplantation to repair large-area infected granulation wounds.
    

6. Clinical Results

• 92 patients had both superficial partial-thickness and deep partial-thickness/full-thickness wounds (only 1 case was pure superficial partial-thickness).
• Superficial partial-thickness wounds healed in 7–10 days post-injury.
• Deep partial-thickness wounds healed in ~14 days post-injury.
• Deep partial-thickness/full-thickness wounds shrank significantly after dressing application, simplifying subsequent surgical management.
• Donor site healing was advanced by 9–10 days.
• Large-area infected granulation wounds achieved primary repair with one-stage mixed transplantation.
