Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
40 words
A method of preserving anatomical specimens including: A. encasing the specimen in an air-tight container; B. exchanging the atmospheric contents within the container surrounding the specimen with an inert gas; and C. irradiating the specimen to destroy bacteria and microorganisms.
Claim 2
Independent Claim
40 words
A method of preserving anatomical specimens including: A. encasing the specimen in an air-tight container; B. exchanging the atmospheric contents within the container surrounding the specimen with an inert gas; and C. irradiating the specimen to destroy bacteria and microorganisms.
Claim 3
Dependent Claim
20 words
The method of claim 1 further including the step of heating the container with the specimen therein to deactivate enzymes.
Claim 4
Dependent Claim
29 words
The method of claim 2 wherein the step of heating the specimen is comprised of heating the specimen to a temperature of approximately 160° F. for approximately one-half hour.
Claim 5
Dependent Claim
13 words
The method of claim 3 wherein the heating is performed with microwave apparatus.
Claim 6
Dependent Claim
29 words
The method of claim 1 wherein the step of irradiating the specimen is comprised of subjecting the container with the specimen therein to x-ray radiation of approximately 10 MeV.
Claim 7
Dependent Claim
30 words
The method of claim 1 wherein the step of irradiating the specimen is comprised of subjecting the container with the specimen therein to gamma ray radiation of approximately 5.6 megarads.
Claim 8
Dependent Claim
35 words
The method of claim 1 wherein the container used to encase the specimen is comprised of a bottom portion on which the specimen is placed and a top portion, adapted to be permanently encased therein.
Claim 9
Dependent Claim
25 words
The method of claim 7 wherein the container includes at least two orifices for exchanging the atmospheric contents within the container with an inert gas.
Claim 10
Dependent Claim
19 words
The method of claim 1 wherein the container used to encase the specimen is comprised of a plastic polymer.
Claim 11
Independent Claim
50 words
A method of storing and preserving anatomical specimens comprising the steps of: A. encasing the specimen in a plastic polymer container; B. replacing the atmospheric contents within the container with an inert gas; C. sealing the container such that it becomes air-tight; D. heating the specimen; E. irradiating the specimen.
Claim 12
Independent Claim
50 words
A method of storing and preserving anatomical specimens comprising the steps of: A. encasing the specimen in a plastic polymer container; B. replacing the atmospheric contents within the container with an inert gas; C. sealing the container such that it becomes air-tight; D. heating the specimen; E. irradiating the specimen.
Claim 13
Dependent Claim
24 words
The method of claim 10 wherein the specimen is heated to a temperature of approximately 160° F. for a period of approximately one-half hour.
Claim 14
Dependent Claim
26 words
The method of claim 10 wherein the step of irradiating the specimen comprises subjecting the specimen within the container to x-ray radiation of approximately 10 MeV.
Claim 15
Dependent Claim
27 words
The method of claim 10 wherein the step of irradiating the specimen comprises subjecting the specimen, within the container, to approximately 5.6 megarads of gamma ray radiation.
