PU film sterile dressing is a common medical dressing, mainly used to cover and protect wounds.
The main material is polyurethane (PU), which is flexible and breathable. The thickness of polyurethane film is relatively thin, and it is less likely to cause discomfort when adhering to the skin. The surface of PU film is usually specially treated to give it certain waterproof performance while allowing air circulation, which helps keep the wound dry.
How is a pu wound dressing?
- Outer layer: Made of PU film, it provides protection and waterproof functions.
- Middle layer: May contain absorbent materials for managing small amounts of exudate.
- Inner layer: Usually made of low-sensitivity adhesive, it ensures a firm adhesion to the skin during application while reducing irritation to the skin.
Applicable scenarios
It is suitable for small superficial wounds. Due to its light, thin and breathable characteristics, it is often used for minor abrasions or cuts in daily life. It can also be used to fix catheters or other medical devices and reduce skin friction.
Usage method
Make sure the wound is clean and dry before use. After opening the package, avoid touching the inner layer of the patch. Apply it directly to the wound and gently press the edge to fix it. Replace it regularly according to the actual situation. If the patch becomes loose or contaminated, it should be replaced in time.
Precautions
●Those allergic to polyurethane or adhesives should use with caution.
●Not suitable for infectious wounds or wounds with a large amount of exudate.
●Store in a cool and dry place, away from high temperatures or direct sunlight.
