Metalline Tracheostomy Dressings are a single-sided, non-adhesive aluminised wound pad, designed for acute wounds at tracheostomy, tube or drain sites. It is comprised of a three-layer system: a nonwoven top layer which encapsulates the absorbent layer, a super-absorbent aluminium coated core which retains exudate, and a perforated viscose contact layer which will not adhere to the wound.
