This invention relates to a method of sterilizing air that contains airborne pathogenic agents or microorganisms such as spores, bacteria, viruses, yeasts and moulds The method consists in damaging and braking up the contaminant molecular structure by oxidation and ionization and chemical bond rupture. Through this process the microorganisms or the contaminants are inactivated through structural damages to the cellular membrane and/or the nucleus membrane and/or to the DNA structure. This is accomplished by creating through the air to be treated, various electronic current having a plurality of specific controlled average kinetic energies matching the desired chemical bonds to be affected and/or ruptured. The air interaction with such various currents, having specific energies, sufficient intensities and exposition time is accomplished through several stages to completely sterilize the air or gas. The air or gas is then processed to remove undesirable by-products that may be present so that it can be used directly or stored.

The method provided by the invention solves the problems that the distance between an ultraviolet sterilization lamp and the sterilized object cannot be adjusted in an existing sterilization process, invalid sterilization occurs in the sterilization process of the ultraviolet sterilization lamp, and the safety is not ensured.

The current invention provides this advance in infection control via its unique application of active sterilization to a catheter or implant. While most catheters, and many implants, are passive devices, the current invention will provide an active component as a integral part of the implanted catheter or device to continuously or intermittently sterilize the exposed surfaces/areas of the device. This active sterilization may be accomplished by a variety of mechanisms, including, application of heat, RF, microwave, ultrasound, ultraviolet radiation or other energy capable of sterilizing the device or dislodging any problematic Biofilm that may form. The active sterilization may also employ the pumping of a sterilizing chemical from an attached drug reservoir, the use of electricity or freezing temperatures or any other mechanism for either inhibiting, killing or dislodging any infectious material in contact with the implant. One major advantage of this design is that through the use of a small, battery powered or inductively powered sterilization element, the implanted catheter or device can be effectively sterilized without requiring the standard removal surgery, waiting period, then replacement of the infected device. This is expected to translate into greatly improved outcomes (particularly for devices where infection may be catastrophic, ie a prosthetic knee or hip), greatly improved costs, and greatly improved longevity of susceptible devices (ie IV ports, etc.).
