Abstract

A sterilization system comprising a sterilization container for holding a surgical instrument, the sterilization container formed to allow sterilant to enter and residual sterilant to exit so that the surgical instrument in the sterilization container can be subjected to a sterilization process. The sterilization container comprises an electronic sensor module for measuring a characteristic of an environment in the sterilization container during a sterilization process. The system further comprises a station capable of being in electronic communication with the sterilization container, with the station comprising a station memory. The station is configured to track usage of the sterilization container on the station memory based on data measured by the electronic sensor module.

Claims (47)

1. A sterilization system, the sterilization system comprising:

a sterilization container for holding a surgical instrument, the sterilization container formed to:

(i) define an anti-microbial barrier around the surgical instrument during and after a sterilization process in a sterilization chamber, wherein the sterilization container is configured to be positioned in the sterilization chamber for a sterilization cycle and thereafter taken out of the sterilization chamber, and

(ii) allow sterilant to enter and residual sterilant to exit so that the surgical instrument in the sterilization container can be subjected to the sterilization process while the sterilization container resides in the sterilization chamber;

an electronic sensor module for measuring a characteristic of an environment in the sterilization container during the sterilization process, wherein the electronic sensor module is coupled to the sterilization container; and

a station configured to electronically communicate with the electronic sensor module of the sterilization container, wherein the station comprises a station memory, and

wherein the station is configured to track, on the station memory and based on data communicated to the station by the electronic sensor module, at least one selected from a group consisting of a location of the sterilization container within a medical facility and a usage of the sterilization container within a medical facility.

2. The sterilization system of claim 1 , wherein the station further comprises a calibration chamber defining an interior configured to receive at least one of the sterilization container or the electronic sensor module.

3. The sterilization system of claim 2 , further comprising at least one of:

a steam generator connected to the calibration chamber and configured to apply a known steam concentration to the interior of the calibration chamber;

a hydrogen peroxide generator connected to the calibration chamber and configured to apply a known hydrogen peroxide concentration to the interior of the calibration chamber;

a pressure pump connected to the calibration chamber and configured to apply a known pressure level to the interior of the calibration chamber;

a vacuum pump connected to the calibration chamber and configured to apply a known vacuum level to the interior of the calibration chamber of the station; and

a heater coupled to the calibration chamber and configured to heat the interior of the calibration chamber of the station to a known temperature.

4. The sterilization system of claim 1 , wherein the station is configured to recharge a battery of the electronic sensor module.

5. The sterilization system of claim 1 , wherein the station further comprising a reader configured to identify a surgical instrument disposed in the sterilization container.

6. The sterilization system of claim 5 , wherein the station is configured to identify a tray to be used with the sterilization container during a sterilization process based on the surgical instrument identified and to provide a proper orientation for placing the surgical instrument on the tray.

7. The sterilization system of claim 6 , wherein the station is configured to provide validated sterilization process measurements for the sterilization process to the electronic sensor module based on at least one of the surgical instrument or the tray identified.

8. The sterilization system of claim 1 , wherein the station further comprises a transceiver, the transceiver includes a wireless transmitter and receiver that can transmit and receive data and instructions via a wireless signal between the station and the electronic sensor module.

9. A method of sterilization, the method comprising the steps of:

providing a sterilization container for holding a surgical instrument, the sterilization container comprising:

(i) an electronic sensor module, and

(ii) an anti-microbial barrier around the surgical instrument during and after a sterilization process in a sterilization chamber in which the sterilization container is placed for a sterilization cycle and thereafter taken out,

wherein the electronic sensor module is configured to measure a characteristic of an environment in the sterilization container during the sterilization process in the sterilization chamber;

electronically communicating data between a station and the electronic sensor module of the sterilization container; and

tracking, based on data communicated to the station from the electronic sensor module, at least one selected from a group consisting of a location of the sterilization container within a medical facility and a usage data for the sterilization container based on data measured by the electronic sensor module.

10. The method of claim 9 , further comprising identifying the surgical instrument disposed within the sterilization container;

identifying a tray to be used with the sterilization container during a sterilization process based on surgical instrument identified; and

providing instructions for placing the surgical instrument in a proper orientation on the tray.

11. The method of claim 9 , further comprising calibrating the electronic sensor module.

12. The method of claim 9 , further comprising recharging a battery of the electronic sensor module.

13. The method of claim 9 , further comprising identifying a number of sterile and non-sterile surgical instruments within a medical facility based, at least in part, on one of the usage data for the sterilization container or the electronic sensor module.

14. The method of claim 9 , further comprising identifying the surgical instrument and/or a tray disposed within the sterilization container; and

providing validated sterilization process measurements for the sterilization process to the electronic sensor module based on at least one of the identified surgical instrument or the identified tray.

15. The method of claim 9 , further comprising generating invoices based, at least in part, on one of the tracked usage data for the sterilization container or the electronic sensor module.

16. The method of claim 9 , further comprising:

inserting the sterilization container in the sterilization chamber; and

after inserting the sterilization container in the sterilization chamber, performing the sterilization cycle; and

after performing the sterilization cycle, removing the sterilization container from the sterilization chamber.

17. The method of claim 9 , wherein the station comprises a handheld reader.

18. The method of claim 9 , wherein the station comprises the sterilization chamber.

19. A sterilization container for holding a surgical instrument, comprising:

a sterile barrier for holding at least one surgical instrument to be sterilized, wherein the sterile barrier is configured for removable insertion in a sterilization chamber, wherein the sterile barrier is configured to allow a sterilant, which is supplied by the sterilization chamber, to enter and residual sterilant to exit so that the surgical instrument in the sterilization container can be subjected to a sterilization process in the sterilization chamber; and

an electronic sensor module for measuring a characteristic of an environment in the sterilization container during the sterilization process,

wherein the electronic sensor module is coupled to the sterile barrier, and

wherein the electronic sensor module is configured to communicate, to a station, data that is suitable to allow the station to track at least one of a group consisting of a location usage of the sterilization container within a medical facility and a usage of the sterilization container within a medical facility.

20. The sterilization container of claim 19 , wherein the electronic sensor module comprises a rechargeable battery.
