OptiLock Non-Adhesive Dressings
Non-adherent and superabsorbent dressing!
The Standard of Gentle Wound Care
OptiLock is a super absorbent polymer core dressing. It takes in a remarkable amount of wound fluid – even under compression – and locks it away to help prevent maceration. Even more, this wound dressing is non-adhesive, meaning minimal disruption to the wound and gentle, pain-free removal.
OptiLock can be used as a primary dressing on partial-thickness and full-thickness wounds, such as: pressure, venous or neuropathic ulcers; post-operative wounds; superficial or partial-thickness burns (first- or second-degree); lacerations; abrasions. OptiLock can also be used as a secondary dressing on full-thickness wounds.
Optilock Features
Absorbs
Super absorbent polymer core absorbs high volumes of exudate.
Locks
Exudate is converted into a gel thats kept firmly away from the wound.
Adjusts
Continually adapts the level of absorption to the amount of wound drainage.
Protects
Does not stick to the wound or periwound skin.

Dispersion Layer
Evenly distributes and quickly transfers exudate into the super-absorbent core.
Blue Protective Backing
Helps protect clothing and sheets.
Super-Absorbent Core
Absorbs large amounts of exudate, which is converted to a gel and locked away from the wound.
