Abstract:
A method for the self-assembled production of a topographically surface structured cellulose element. First, a mold is provided having on one side a first surface which is in a complementary manner topographically structured and which is permeable to oxygen. Next, a liquid growth medium containing cellulose producing bacteria is provided. Then, the mold is placed to form a interface such that the side of the mold with the first surface is in direct contact with the liquid growth medium, and an opposite side is facing air or a specifically provided oxygen containing gas surrounding. This allows bacteria to be produced and deposit cellulose on the first surface and developing on the interface a surface structured surface complementary thereto, until a cellulose layer with a thickness of the element of at least 0.3 mm is formed. Finally; the element is removed from the mold.
Abstract:
A wound care system for promoting wound healing and for preventing infections thereof and a method for producing the same includes an anti-microbial solution and a multi-layer wound dressing. The anti-microbial solution contains a mixture of colloidal silver, colloidal copper and colloidal zinc oxide mixed in sterile purified water. The multi-layer wound dressing is formed of a contact layer, an intermediate layer, and an outer layer. The solution is poured onto the wound dressing which is subsequently placed directly over a wound so as to provide and maintain a moist environment. In other embodiments, there are provided anti-microbial solutions and methods for producing the same, functioning as stand-alones and containing a mixture of at least two elements of colloidal silver, colloidal copper, and colloidal zinc.
Abstract:
The present invention relates to water soluble quaternized chitosan derivatives which form hydrogel matrix with broad antimicrobial properties for the protection and coating of medical device. Hydrogel is attractive as an antimicrobial coating since its hydrophilicity intrinsically prevents the reversible nonspecific attachment of microbes. In order to achieve hydrogel formation, quaternized chitosan can be grafted with polymerizable groups, especially photocrosslinkable groups, such as methacrylates, PEG derivatives and be converted into hydrogels through a thermal or UV polymerization process. Hydrogels are hydrated cross-linked polymeric systems that contain water in an equilibrium state forming cushion water shield. The present invention is widely used in many medical devices. This invention describes the formation of novel hydrogels based on quaternized ammonium chitosan derivatives which has been grafted with photocrosslinkable groups, hence providing hydrogels as antimicrobial water shield coating agent.

Abstract:
A plasma coating device for treating a wound comprises a plasma chamber having: one or more electrodes, a gas supply inlet, a plasma outlet exposed to ambient pressure, and an ignition system operatively connected to the electrodes for providing a non-thermal equilibrium plasma within the plasma chamber. An aerosol delivery system is operable to introduce a bioresorbable material as an aerosol into the plasma, to produce a coating on the wound surface.
