Abstract
This apparatus and method improves the way metal and other objects will be sterilized, disinfected and preserved by utilizing both electromagnetic radiation (UV light in particular) to kill anaerobic pathogens and oxygen depletion to kill aerobic pathogens. The removal of the presence of oxygen further increases the useful lifespan of the treated object by preventing corrosion in general and oxidation in particular.
Description
- This application claims benefit of U.S. patent application Ser. No. 12/062,221 filed Apr. 3, 2008 and issued as U.S. Pat. No. 8,278,628 on Oct. 2, 2012; which in turn claims the benefit of U.S. Provisional Application No. 60/909,811, filed Apr. 3, 2007 (all hereby incorporated by reference).
- An improved apparatus and process for sterilization and preservation of objects is disclosed that can be used to disinfect, sterilize and preserve metal objects through the use of ultraviolet light. Although machines that sterilize metal objects through the use of ultraviolet light already exist, one preferred embodiment of the apparatus and process sterilizes metal using a new and novel apparatus and method, in which a vacuum is created that will remove all of the air and oxygen from the container containing the metal object that is to be sterilized with ultraviolet radiation. Optionally, the removed air can be replaced by an inert gas such as nitrogen. This process of removing air from the container and optionally replacing the air with inert gas has two advantages: 1) decreases the pathogenicity of aerobic flora and therefore aerobic pathogens will die in the absence of O2 and the object will remain sterilized and 2) the metal object will not oxidize or rust.
-
FIG. 1 is a schematic diagram showing a preferred embodiment of the present invention; and -
FIG. 2 is a drawing of a preferred embodiment of the present invention. - Referring now to the drawings where
FIG. 1 is a schematic drawing of a general embodiment of the present invention andFIG. 2 is a further specific preferred embodiment, reference numbers inFIG. 2 which correspond to elements inFIG. 1 have been raised by 100. Only unique elements toFIG. 2 will be discussed separate from the elements in the general embodiment ofFIG. 1 . - The apparatus includes a canister 1 having a
work chamber 2 into which the object 3 to be sterilized, disinfected and preserved is inserted and secured. The canister 1 will be a (preferably) clear material (including but not limited to glass, composite plastic, or metal). The canister 1 will be constructed in order to achieve and maintain an ideal vacuum. It will open sufficiently to allow emplacement of the target object. The canister 1 could be lined with a reflective material. Twoairtight valves chamber 2. The source at the inert gas would be a separate tank or agas generator 5. The exchange of gas for the vacuum will allow for reduction of pressure on thevalve seals chamber 2 and the seals 6) and will allow for continued aerobic pathogenesis. The source of the nitrogen gas can be a tank or anitrogen generator 5 that separates nitrogen gas from the air. The exchange of the gases will reduce the pressure on theairtight seals 6. Furthermore, it will ensure the cessation of oxidation and death of aerobic pathogens which need oxygen to survive. - The
chamber 2 will include a compartment 7 which will be exposed to the vacuum. Thechamber 2 will contain a dessilant 8 such as silica gel to remove H2O. Thechamber 2 also will contain an oxygen scavenger 9 to remove O2. - The intensity of the
electromagnetic radiation source 10 varies inversely with the square of the distance from the source. Theelectromagnetic radiation source 10 should in close proximity to the object 3 being exposed. The source of the electromagnetic radiation either inside of the canister 1 or outside of the canister 1. A cable 12 could be used to transmit the wavelengths of interest to the inside of the canister. - UV light will degrade plastic, therefore, the canister 1 should be made of a UV-resistant material that will not degrade as quickly.
- Depending upon the scale of the target objects, the vacuum needed for atmospheric replacement may be done by a large electronic or
smaller hand pump 5. There are several options for the production of a vacuum. For larger scale industrial use or hospital use, a large vacuum pump can be used. For residential use, a hand pump could be utilized. - A timer 14 will be incorporated with an on/off switch 15 to indicate the completion of the process and to control the electromagnetic radiation source. The user will have the option of keeping the sterilized and disinfected object in the canister, in the non-corrosive atmosphere until ready for use.
Claims (9)
1. An apparatus for sterilization and preservation of an object using electromagnetic radiation, comprising:
a canister provided with an opening for insertion of an object;
a vacuum-tight seal of the opening of the canister to thereby allow a vacuum to be created and maintained within the canister;
a light source which generates electromagnetic radiation directed toward metal objects within said canister; and
a device for removing air from inside the canister to thereby create a vacuum in the housing.
2. The apparatus of claim 1 , wherein the device for removing air comprises a device for removing oxygen.
3. The apparatus of claim 1 , wherein the device for removing air generates a vacuum within the housing.
4. The apparatus of claim 1 , wherein the light source generates UV light which is directed into the canister for sterilizing and preserving metal objects placed therein.
5. The apparatus of claim 4 , wherein the light source generates an electromagnetic radiation sufficient to sterilize an object within the canister.
6. The apparatus of claim 1 , further comprising a gas source for generating gas to be pumped into the canister.
7. The apparatus of claim 6 , wherein the gas source generates an inert gas to be pumped into the canister.
8. The apparatus of claim 7 , wherein the inert gas is nitrogen.
9. The apparatus of claim 1 , wherein the canister is lined with reflective material.
