Sterilization device for sterilizing medical or surgical instrument for dental usage, has sterilization indicator provided with photon detection unit for detecting photons emitted in sterilization chamber through plasma

摘要

The device has a gas injecting unit (1) i.e. conduit, for nitrogen flow transversing an enclosure (2) under vacuum subjected to an electric field produced by a micro-wave generator (3) to produce the plasma of the nitrogen. A sterilization chamber (4) i.e. post-discharge chamber, receives the plasma in a post-discharge area, and a sterilization indicator (17) is provided with a photon detection unit for detecting photons emitted in the sterilization chamber through the plasma. The sterilization indicator is used for detecting photons having a wavelength of 580 nanometer (Nm). An independent claim is also included for a method for indicating the presence of a given quantity of nitrogen atoms in a post-discharge plasma during sterilization process.
