What is the role of polyurethane foam dressing

Polyurethane Foam Dressings Dry traditional dressings that provide supervised coverage of the wound. Can not be used for infected wounds, does not promote wound healing, has limited ability to manage exudate, adheres to wounds, re-injures new epithelial tissue and causes bleeding, and patients are painful after changing dressings.
Oil gauze, containing petrolatum or triglycerides, can play a role in non-adhesion to the wound. Polyurethane foam dressings promote the overall healing process of wounds; are ineffective for infected wounds; can drain exudate to 2 layers of dressing, with limited exudate management capabilities.
Polyurethane foam dressing is an important function of modern wound dressings in that it replaces the important function of damaged skin and continues to act until wound healing and skin lesion healing. It: resists mechanical factors (such as dirt, bumps, inflammation, etc.), resists pollution and chemical irritation, prevents secondary infections, prevents dryness and loss of body fluids (loss of electrolytes), prevents heat loss.
In addition to comprehensive protection of wounds, polyurethane foam dressings can actively affect the wound healing process through debridement and create a microenvironment that promotes wound healing.
Interactive Dressing, Polyurethane Foam Dressing Contains Super Absorbing Acrylate Polymer, Activated by Ringer's Solution, Releases Ringer's Solution for 24 Hours Continuous, Active, Powerful Cleaning of Wounds, Suitable for All Opens Wounds (except narrow and deep wounds), including infected wounds and various stages of healing, especially debridement.
Silver dressing, silver ions can directly kill bacteria, control wound infection, speed up wound healing, and remove odor caused by bacteria. It is an ideal anti-infective dressing.
Polyurethane foam dressing, a mixture of alginic acid and calcium ions, forms a smooth gel after contact with wound exudate and oozing blood, protects the wound surface, and effectively promotes wound healing. Foam dressings, most of which are made of water molecule materials, are covered with a polyurethane semi-permeable membrane. High exudate absorption capacity, efficient exudate management ability, highly hydrophilic material, reduce the risk of wound adhesion, promote wound healing, foam cushion cushions external pressure.
The polyurethane foam dressing adopts the principle of sealing and moisturizing. The hydrophilic CMC particles are in contact with the wound exudation, and a layer of moist gel is formed on the wound surface, which continuously creates a moist environment and does not adhere to the wound surface. It is a hydrophilic polyurethane polymer with high water content, which can automatically adjust the wetness of the wound, has the ability to absorb a small amount of exudate, does not stick to the wound, and is easy to remove.
