Abstract
An apparatus and process for hydrogen peroxide vapor sterilization of medical instruments and similar devices make use of hydrogen peroxide vapor released from a substantially non-aqueous organic hydrogen peroxide complex, such as a urea-peroxide complex. Optionally, a plasma can be used in conjunction with the vapor. A method for preparing substantially non-aqueous hydrogen peroxide complexes is also provided. These complexes are useful as a source of peroxide vapor in hydrogen peroxide vapor sterilizers and as a component of self-sterilizing packaging materials.
Claims19
A process for preparing a substantially non-aqueous hydrogen peroxide complex, comprising the steps of:
- evacuating a chamber that contains a composition capable of reacting with hydrogen peroxide vapor to a pressure that is below the vapor pressure of said hydrogen peroxide vapor;
- then
- introducing the hydrogen peroxide vapor into the chamber, wherein the hydrogen peroxide vapor reacts with the composition to form the hydrogen peroxide complex.
