Abstract

A system for sanitizing or sterilizing an item and storing the item in a sanitized or sterile environment. The system includes an enclosure into which a sealable package containing the item is placed. At least one ozone source is configured to introduce ozone inside the package. The ozone sterilizes the interior of the package and the item. The ozone source can include an electron beam which ionizes the oxygen, a corona discharge generated within the package, or Vacuum Ultra-Violet (“VUV”) radiation emitted into the package. A germicidal radiation source can be used to sanitize the item and generate ozone. The package containing the item is substantially transparent to germicidal radiation so that the germicidal radiation sanitizes the item as well as the interior of the package. Ultrasonic transducers can introduce ultrasonic energy into the item being sanitized, to break apart groups of clumped pathogens resident on the item.

Claims

1. A system for sterilizing an item and storing the item in a sterile environment, the system comprising:

a package having an interior volume for containing the item being sterilized, the package being sealable and substantially impermeable to ozone; and

at least one ozone source configured to introduce ozone inside the package;

wherein the ozone sterilizes the interior volume of the package and the item contained therein.

2. The system of claim 1, wherein the ozone source includes:

a current source;

a primary coil connected to the current source and located outside of the package; and

the package includes;

a secondary coil located within the package and configured so as to derive a voltage from the primary coil; and

a spark gap connected to the secondary coil such that the voltage across the spark gap and an associated corona discharge generate ozone within the package.

3. The system of claim 1, further comprising at least one microwave source having a focusing surface focused so as to generate a high microwave intensity within the package,

wherein the package has at least one dimension that is approximately a multiple of a resonant frequency of the microwave, and

the microwave power focused at within the package results in a gas discharge plasma thereby generating ozone within the package.

4. The system of claim 1, further comprising:

a sterilizing enclosure; and

at least one radiation source configured to emit radiation having a predetermined wavelength within the sanitizing enclosure,

wherein at least a portion of the package is substantially transparent to the emitted wavelength of radiation, so as to expose the item to the radiation.

5. The system of claim 4, wherein the sanitizing enclosure includes at least one interior wall that reflects the predetermined wavelength of radiation.

6. The system of claim 4, wherein the predetermined wavelength includes VUV radiation, and the VUV radiation entering the package generates ozone in the interior volume of the package.

7. The system of claim 6, wherein the predetermined wavelength of the at least one radiation source includes at least one of about 185 nm and about or 172 nm.

8. The system of claim 4, wherein the at least one radiation source is coupled to the package proximate the portion of the package substantially transparent to the emitted radiation.

9. The system of claim 1, wherein the package includes a transmission window substantially permeable to electrons in a predetermine kinetic energy range, the system further comprising an electron beam source configured to emit an electron beam toward the transmission window so as to ionize gas contained in the package and generating ozone within the package.

10. The system of claim 9, wherein the transmission window comprises a ceramic foil.

11. The system of claim 9, wherein the electron beam source includes a cathode and an anode.

12. The system of claim 9, wherein the electron beam source is coupleable to the transmission window.

13. The system of claim 1, further comprising:

a sterilizing enclosure;

an ozone sensor configured to measure the ozone within the enclosure; and

a lockable opening coupled to the enclosure, the lockable opening configured to lock while the ozone sensor senses a predetermined concentration of ozone in the enclosure.

14. The system of claim 1 further comprising:

an ultrasonic transducer coupled to the package so as to introducing ultrasonic energy to the package and the item contained therein and declump pathogens.

15. The system of claim 1, further comprising:

a sterilizing enclosure; and

an ozone removal device coupled to the enclosure.

16. The system of claim 15, wherein the ozone removal device includes a heated element through which the gas inside the enclosure is exhausted.

17. The system of claim 1, further comprising a hot water bath configured to receive the item being sterilized for a predetermined period of time, prior to insertion of the item into the package.

18. The system of claim 17, wherein the hot water bath can boil water placed within the bath.

19. The system of claim 17, wherein the hot water bath is further configured to produce a vacuum above the surface of the water.

20. A system for sanitizing an item within a sanitary package, the system comprising:

a sanitizing enclosure;

at least one germicidal radiation source configured to emit germicidal radiation within the sanitizing enclosure;

a package for containing the item and being placed within the sanitizing enclosure, the package comprising a material that is substantially transparent to germicidal radiation.

21. The system of claim 20, wherein the sanitizing enclosure includes at least one interior wall that reflects germicidal radiation.

22. The system of claim 20 further comprising an ultrasonic transducer coupled to the package so as to introducing ultrasonic energy to the package and the item contained therein and declump pathogens.

23. The system of claim 20, wherein the at least one germicidal radiation source substantially lines the interior of the sanitizing enclosure.

24. The system of claim 20, wherein the package comprises woven quartz.

25. The system of claim 20, wherein the package comprises OP-4.

26. The system of claim 20, wherein the at least one germicidal radiation sources comprises a planar RF-excited radiation source.

27. The system of claim 20, wherein the package further comprises a protrusion for insertion into shadowed volumes of the item, the rod configured to introduce germicidal radiation within the volume.

28. The system of claim 27, wherein the protrusion includes a quartz waveguide, the protrusion being coupleable to the germicidal radiation source.

29. The system of claim 27, wherein the protrusion includes a second germicidal radiation source at a distal end of the protrusion.

30. The system of claim 20, wherein the germicidal source produces VUV radiation so as to generate ozone within the pouch.

31. The system of claim 20, further comprising:

a current source;

a primary coil connected to the current source and located outside of the package;

a secondary coil located within the package and configured so as to induct a voltage from the primary coil; and

a spark gap connected to the secondary coil such that the voltage across the spark gap generates ozone within the package.

32. The system of claim 20, further comprising a hot water bath configured to receive the item being sterilized for a predetermined period of time, prior to insertion of the item into the package.
