The main function of sterile patches is to facilitate wound healing. Aseptic patches are suitable for surgery, trauma, wounds, or venous catheterization. They can also be used for the protection of infant umbilical cord wounds. The main components are medical pressure-sensitive adhesive non-woven fabric, suction pads, and isolation paper. Patients should regularly replace sterile patches when using them, and the usage time should not exceed 12 hours, otherwise local itching and swelling may occur.

1、 What comes into contact with the human body are non-woven fabrics coated with pressure-sensitive adhesive and absorbent cotton (composed of a soft non-woven fiber layer coated with low allergenic polyacrylate adhesive and a pure cotton fiber absorbent pad core).

2、 The part in contact with the wound is a hydrophobic porous layer, which keeps the wound dry without adhesion, and has a good absorption and cushioning effect.

3、 The secretion is quickly drained into the absorption pad after passing through the porous wound contact layer.
