Abstract
The present invention concerns antimicrobial multi-layer wound dressings having an antimicrobial agent located at one or more interfaces between opposing surfaces of the layers of the wound dressing. This improves the migration of antimicrobial agent and allows the dressing to provide a higher overall concentration of antimicrobial agent throughout the dressing. This will assist clinicians when treating wounds by reducing the microbial load at the wound bed thereby reducing the risk of wound infection.
Claims17
A multi-layer wound dressing comprising at least a first layer and a second layer, wherein the first layer is adjacent to the second layer and bonded thereto;
- and an antimicrobial agent, wherein the antimicrobial agent is in the form of a powder located at an interface between opposing surfaces of the first layer and the second layer, and wherein the antimicrobial agent is not directly attached or bound to the first and second layers, wherein the first and second layers are bonded by a powder adhesive at the interface between opposing surfaces of the first layer and the second layer, and the antimicrobial agent is mixed with the adhesive.
A method of manufacturing a multi-layer wound dressing, the method comprising the steps of applying an antimicrobial agent to a surface of a first layer and/or a second layer, locating the first and second layers adjacent to each other and bonding the first layer to the second layer, such that the antimicrobial agent is in the form of a powder located at an interface between opposing surfaces of the first layer and the second layer, and wherein the antimicrobial agent is not directly attached or bound to the first and second layers, wherein the first and second layers are bonded by a powder adhesive at the interface between opposing surfaces of the first layer and the second layer, and the antimicrobial agent is mixed with the adhesive.
