Abstract

A battery-powered tracking component may be attached to a sterilization case. The tracking component may collect, store and transmit usage information associated with the sterilization case. The supplying of power to the tracking component may be temporarily stopped during autoclave processes. As the high temperatures and pressurized steam of autoclave processes may drain an active battery, the lifespan of the battery may be elongated by deactivating the battery during the autoclave processes. A temperature sensor may detect when the temperature of the sterilization case rises above a threshold indicating a start of the autoclave process, and when the temperature of the sterilization case falls below a threshold indicating an end of the autoclave process. The usage information may include a count of autoclave processes and durations of time periods between autoclave processes. The usage information may be used to determine times at which autoclave processes are performed.

Claims (40)

1 . A method comprising:

supplying power to a tracking component that is battery-powered and that collects, stores, and transmits usage information associated with a sterilization case in which medical instruments are sterilized and stored;

detecting an initiation condition indicative of an initiation of a first autoclave process that sterilizes the medical instruments in the sterilization case;

stopping, based on the initiation of the first autoclave process, the supplying of the power to the tracking component;

detecting a completion condition indicative of a completion of the first autoclave process; and

resuming, based on the completion of the first autoclave process, the supplying of the power to the tracking component.

2 . The method of claim 1 , wherein the initiation condition is an increase to a temperature of the sterilization case.

3 . The method of claim 1 , wherein the completion condition is a decrease to a temperature of the sterilization case.

4 . The method of claim 1 , wherein the usage information comprises durations of time periods between autoclave processes.

5 . The method of claim 1 , wherein the usage information comprises a count of autoclave processes that are performed on the sterilization case.

6 . The method of claim 1 , further comprising:

transmitting the usage information to a computing device that is external to the sterilization case.

7 . The method of claim 6 , further comprising:

determining a location of the sterilization case based on a location of the computing device.

8 . The method of claim 1 , further comprising:

obtaining, by a computing device, from the tracking component, the usage information; and

determining a first complete time at which the first autoclave process is completed, wherein the usage information comprises a first duration of a first time period between the completion of the first autoclave process and an obtain time at which the usage information is obtained from the tracking component by the computing device, and wherein the first complete time at which the first autoclave process is completed is determined by subtracting the first duration from the obtain time at which the usage information is obtained from the tracking component by the computing device.

9 . The method of claim 8 , wherein the usage information further comprises a second duration of a second time period between the initiation of the first autoclave process and a completion of a second autoclave process.

10 . The method of claim 9 , further comprising:

determining a second complete time at which the second autoclave process is completed by subtracting the first duration, the second duration, and an estimated autoclave process duration from the obtain time at which the usage information is obtained from the tracking component by the computing device.

11 . A method comprising:

supplying power to a tracking component that is battery-powered and that collects, stores, and transmits one or more time parameters associated with a sterilization case in which medical instruments are sterilized and stored;

detecting an initiation condition indicative of an initiation of a first autoclave process that sterilizes the medical instruments in the sterilization case;

stopping, based on the initiation of the first autoclave process, the supplying of the power to the tracking component;

detecting a completion condition indicative of a completion of the first autoclave process; and

resuming, based on the completion of the first autoclave process, the supplying of the power to the tracking component.

12 . The method of claim 11 , wherein the initiation condition is an increase to a temperature of the sterilization case.

13 . The method of claim 11 , wherein the completion condition is a decrease to a temperature of the sterilization case.

14 . The method of claim 11 , wherein the one or more time parameters comprise durations of time periods between autoclave processes.

15 . The method of claim 11 , wherein the tracking component further collects stores and transmits a count of autoclave processes that are performed on the sterilization case.

16 . The method of claim 11 , further comprising:

transmitting the one or more time parameters to a computing device that is external to the sterilization case.

17 . The method of claim 16 , further comprising:

determining a location of the sterilization case based on a location of the computing device.

18 . The method of claim 11 , further comprising:

obtaining, by a computing device, from the tracking component, the one or more time parameters; and

determining a first complete time at which the first autoclave process is completed, wherein the one or more time parameters comprise a first duration of a first time period between the completion of the first autoclave process and an obtain time at which the one or more time parameters are obtained from the tracking component by the computing device, and wherein the first complete time at which the first autoclave process is completed is determined by subtracting the first duration from the obtain time at which the one or more time parameters are obtained from the tracking component by the computing device.

19 . The method of claim 18 , wherein the one or more time parameters further comprise a second duration of a second time period between the initiation of the first autoclave process and a completion of a second autoclave process.

20 . The method of claim 19 , further comprising:

determining a second complete time at which the second autoclave process is completed by subtracting the first duration, the second duration, and an estimated autoclave process duration from the obtain time at which the one or more time parameters are obtained from the tracking component by the computing device.
