[0002] Healing membrane, a new ultra-thin and comfortable dressing, is produced using contemporary international high-tech. It is a special semi-permeable membrane with good waterproof, antibacterial, breathable, hypoallergenic, transparent, and high elasticity. When using, clean and disinfect the wound, and then take out the sterile medical transparent dressing from the packaging bag. From one end of the transparent dressing, peel off the paper with words to expose the adhesive surface. Hold both ends, stick the adhesive surface to the skin, and smooth it from the middle to the surrounding. It is used for intravenous injection, catheter fixation and various wound treatment protection in hospitals. It is a skin beauty protection, family medicine box, military training exercises, wartime first aid, and factory construction sites. Remove the frame from the side without words.
