Abstract
An oxygen releasing bandage or dressing is based on a stable complex between polyvinyl acetal and hydrogen peroxide. Medical grade polyvinyl acetal sponge is treated with hydrogen peroxide, thereby forming a complex between the acetal plastic and the hydrogen peroxide. The dressing material is then affixed to a wound preferably with an oxygen impermeable covering. Fluids from the wound are drawn into the sponge where catalase and other enzymes in the fluids breakdown the hydrogen peroxide to release oxygen. If treatment of relatively dry wounds is desired, catalyst solutions can be introduced into the bandage to stimulate production of oxygen. The bandages are stable for a prolonged period of time.
Claims13
A bandage or dressing for providing oxygen to stimulate wound healing comprising a polyvinyl acetal sponge containing hydrogen peroxide-polyvinyl acetal complex.
A dressing or bandage for providing oxygen to a wound comprising:
- a polyvinyl acetal sponge containing polyvinyl acetal-hydrogen peroxide complex;
- and
- an oxygen impermeable membrane to cover the sponge and retain oxygen.
A method for producing an oxygen generating bandage material containing hydrogen peroxide-polyvinyl acetal complex comprising the steps of contacting polyvinyl acetal with hydrogen peroxide and removing unbound hydrogen peroxide thereby leaving polyvinyl acetal-hydrogen peroxide complex.
