Controlled oxygen/anti-microbial release films

A film which releases at least one of an antimicrobial agent and oxygen, the film comprising:

• a layer of a flexible, porous material;
• a dry perborate substantially constrained in association with the porous, flexible material layer;
• a dry reagent including at least one of a phosphate, acetylsalicylic acid, tetraacetyl ethylenediane (TAED), diactyl dioxohexahydratriazine (DADHT), tetraacetyl glycoluril, and sodium nanonoyl oxygenzene sulfonate constrained in association with the flexible, porous material layer;
• a means for maintaining the perborate and the dry reagent separated in the absence of the dilutant and in the presence of a dilutant, enabling the first and second dry reagents to dissolve and interact generating in situ at least one of the antimicrobial agent solution and oxygen.

A film which releases at least one of an antimicrobial agent and an oxidant, the film comprising:

• an inner layer of a flexible, porous material;
• a first outer layer of a flexible, porous material, the first outer layer being connected on a first side of the inner layer;
• a second outer layer connected on a second side of the inner layer;
• an acetyl donor constrained between the inner layer and the first outer layer;
• and
• a persalt constrained between the second outer layer and the inner layer, the persalt and the acetyl donor being reactive in the presence of a dilutant to create in situ a solution containing the antimicrobial agent or the oxidant.

A film which releases at least one of an antimicrobial agent and an oxidant, the film comprising:

• a layer of a flexible, porous material;
• a first dry reagent including at least one of acetylsalicylic acid, tetraacetyl ethylenediane (TAED), diactyl dioxohexahydratriazine (DADHT), tetraacetyl glycoluril, sodium nanonoyl oxygenzene sulfonate, and phosphate substantially constrained in association with the porous, flexible material layer;
• a second dry reagent including a perborate constrained in association with the flexible, porous material layer, the first and second reagents being reactive in the presence of a dilutant in situ to create a solution containing at least one of the antimicrobial agent and the oxidant;
• a means for controlling a reaction rate between the first and second reagents.

A film which releases at least one of an antimicrobial solution and oxygen, the film comprising:

• a layer of a flexible, porous material;
• a persalt substantially constrained in association with the porous, flexible material layer;
• an acetyl donor comprising at least one of acetylsalicylic acid, tetraacetyl ethylenediane (TAED), diactyl dioxohexahydratriazine (DADHT), tetraacetyl glycoluril, and sodium nanonoyl oxygenzene sulfonate constrained in association with the flexible, porous material layer and separated from the first reagent, the persalt and the acetyl donor being brought together and reacting in the presence of a dilutant to form in situ at least one of the antimicrobial solution and oxygen;
• a means for controlling a rate at which the persalt and the acetyl donor react such that a rate at which the at least one of the antimicrobial solution and oxygen is released is controlled, the reaction rate controlling means including at least one of:
• a porous outer layer which limits a rate of dilutant ingress to the persalt and the acetyl donor;
• micro-encapsulation of at least one of the persalt and the acetyl donor, which micro-encapsulation dissolves at a controllable rate;
• a buffer for buffering a pH during the reaction;
• and
• a separating filter layer for controlling access of the persalt and the acetyl donor to each other.
