  • Device for gaseous plasma sterilization
    Patent number: 7928339
    Abstract: A device for producing a gas plasma by ionisation of a gas using a microwave source of determined nominal power (Pn), includes a magnetron 7 receiving its electric energy from a supply circuit. The device is characterized in that the power (Pd) delivered by the supply circuit to the magnetron 7 is no more than one quarter of the nominal power (Pn) of the magnetron 7.

  • Post-discharge plasma sterilisation device and method
    Patent number: 7927557
    Abstract: A device used for the sterilization of objects (19), in particular medical or surgical instruments, is of the type that can create a gaseous plasma from a gas flow which is subjected to an electric field. The resulting post-discharge flow is brought into contact with the surface of the objects to be treated. The device is characterized in that the gas flow includes exclusively nitrogen. Moreover, the device include a device for heating the aforementioned objects, which can heat the objects to a temperature of at least 60° C. during treatment. A method of using the device is also described.
