Abstract
Abstract A method and apparatus for providing sterile, charged batteries for use in a sterile field. The method includes the steps of placing at least one battery in a sterilization container, sterilizing the battery within the container, charging the battery while maintaining it in a sterile state within the container, and transferring the sterile, charged battery in a sterile state to the sterile field. The container is adapted to permit the entrance of a sterilant and to prevent the entrance of contaminants. The container may include an integral battery charger adapted to withstand exposure to the environment of a sterilization process. Alternatively, the container may include a connector for releasably electrically connecting the battery housed within the container to a distinct, external battery charger.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
88 words
A method of providing sterile, charged batteries for use in a sterile field comprising the steps of: placing at least one battery in a sterilization container; sterilizing said battery within said container; charging said battery to a desired voltage while maintaining said battery in a sterile state within said container; and transferring said sterile, charged battery in a sterile state to the sterile field, said container being permeable to sterilant but impermeable to contaminants and being adapted to provide electrical communication between a battery charger and said battery.
Claim 2
Independent Claim
88 words
A method of providing sterile, charged batteries for use in a sterile field comprising the steps of: placing at least one battery in a sterilization container; sterilizing said battery within said container; charging said battery to a desired voltage while maintaining said battery in a sterile state within said container; and transferring said sterile, charged battery in a sterile state to the sterile field, said container being permeable to sterilant but impermeable to contaminants and being adapted to provide electrical communication between a battery charger and said battery.
Claim 3
Dependent Claim
22 words
A method as recited in claim 1 wherein said battery is charged by electrically connecting said container to an external battery charger.
Claim 4
Dependent Claim
63 words
Apparatus for providing at least one sterile, charged battery for use in a sterile field comprising: a container adapted to permit the entrance of a sterilant and to prevent the entrance of contaminants, said container being adapted to house said battery during sterilization and storage, and said container having means for charging said battery therein while maintaining said battery in a sterile state.
Claim 5
Dependent Claim
63 words
Apparatus for providing at least one sterile, charged battery for use in a sterile field comprising: a container adapted to permit the entrance of a sterilant and to prevent the entrance of contaminants, said container being adapted to house said battery during sterilization and storage, and said container having means for charging said battery therein while maintaining said battery in a sterile state.
Claim 6
Dependent Claim
29 words
Apparatus as recited in claim 3 wherein said charging means is a battery charger integrally connected to said container and adapted to withstand exposure to the environment during sterilization.
Claim 7
Dependent Claim
13 words
Apparatus as recited in claim 4 wherein said battery charger is hermetically sealed.
Claim 8
Dependent Claim
34 words
Apparatus as recited in claim 3 wherein said charging means is a connector for releasably electrically connecting said battery housed within said container to a battery charger distinct from and external to said container.
Claim 9
Dependent Claim
123 words
An assembly for providing sterile, charged batteries for use in a sterile field comprising: a container, at least one battery and a battery charger; said container being adapted to permit the entrance of a sterilant and to prevent the entrance of contaminants and said container being adapted to so house said at least one battery that said battery is sterilized within said container when said container is exposed to a sterilization process and said battery is maintained in a sterile state when stored in said container subsequent to the exposure to said sterilization process; and said container having means to electrically connect said battery to said battery charger for charging said battery within said container while maintaining said battery in said sterile state.
Claim 10
Dependent Claim
123 words
An assembly for providing sterile, charged batteries for use in a sterile field comprising: a container, at least one battery and a battery charger; said container being adapted to permit the entrance of a sterilant and to prevent the entrance of contaminants and said container being adapted to so house said at least one battery that said battery is sterilized within said container when said container is exposed to a sterilization process and said battery is maintained in a sterile state when stored in said container subsequent to the exposure to said sterilization process; and said container having means to electrically connect said battery to said battery charger for charging said battery within said container while maintaining said battery in said sterile state.
Claim 11
Dependent Claim
31 words
An assembly as recited in claim 7 wherein said battery charger is integrally connected to said container and is sealed to withstand exposure to the environment present during said sterilization process.
Claim 12
Dependent Claim
49 words
An assembly as recited in claim 7 wherein said container includes a connector for releasably electrically connecting said battery housed within said container to said battery charger, said battery charger being distinct from said container and being adapted to releasably engage said connector on the exterior of said container.
Claim 13
Dependent Claim
35 words
An assembly as recited in claim 7 wherein said container is further adapted to house a tool during said sterilization process to maintain said tool in a sterile state for use in said sterile field.
