Abstract

The invention provides devices and methods for sterilization/disinfection control of medical devices. In particular, a system is provided which comprises (i) an enclosure which is configured to deliver UV light for purposes of sterilization and/or disinfection; and (ii) one or more medical devices. The enclosure and medical device(s) are configured to communicate such that the system recognizes the identity of the medical device, recognizes that sterilization/disinfection has occurred, and electronically stores data related to the sterilization/disinfection of the medical device(s) within the enclosure. This data storage can occur on the medical device(s) themselves, or on a remote computer.

Claims

1. A method for sterilization/disinfection control of medical devices, comprising:

placing at least one medical device comprising a unique identifier associated therewith in an enclosure configured to deliver UV light within the enclosure, wherein the enclosure is operably coupled with a first processing system comprising a first transceiver and a first microprocessor to generate data to related to the sterilization/disinfection of the medical device;

sterilizing or disinfecting the medical device within the enclosure by exposing the medical device by causing the enclosure to deliver the UV light;

transmitting the data to related to the sterilization/disinfection of the medical device via the first transceiver to a second processing system comprising a second transceiver and a second microprocessor; and

storing the data related to the sterilization/disinfection of the medical device on an electronic storage medium associated with the second processing system, wherein the stored data is correlated to the unique identifier of the medical device.

2. A method according to claim 1, wherein a sterilization/disinfection cycle delivers between 10,000-250,000 mWs/cm² of UV light within the enclosure

3. A method according to claim 1, wherein the UV light comprises UV-C light.

4. A method according to claim 1, wherein the unique identifier comprises at least one of an RFID tag, RuBee tag, or bar code, etc. which is interrogated by a corresponding reader.

5. A method according to claim 1, wherein the unique identifier comprises data stored in an internal memory of the medical device, and wherein the unique identifier is interrogated by a corresponding reader querying a microprocessor within the medical device which is operably coupled to the internal memory.

6. A method according to claim 5, wherein the reader is external to the enclosure, and the device is interrogated for its unique identifier prior to placement of the device within the enclosure.

7. A method according to claim 5, wherein the reader is within the enclosure, and the unique identifier is interrogated following placement of the device within the enclosure.

8. A method according to claim 1, wherein the second processing system is contained within the medical device.

9. A method according to claim 1, wherein the second processing system is a computer which is remote from both the medical device and the enclosure.

10. A method according to claim 1, wherein the data to related to the sterilization/disinfection of the medical device comprises data indicative of the last time the medical device has been sterilized, and/or data indicative of whether the medical device has been used on a patient since that time.

11. A system for practicing a method according to claim 1, the system comprising:

an enclosure, wherein the enclosure is configured to deliver UV light within the enclosure, and wherein the enclosure is operably coupled to a first processing system comprising a first transceiver and a first microprocessor, the first processing system configured to generate data to related to sterilization/disinfection cycles initiated within the enclosure and to transmit the data via the first transceiver; and

at least one medical device comprising a unique identifier associated therewith;

a second processing system comprising a second transceiver and a second microprocessor, the second processing system configured to receive the data from the first transceiver and store the data on an electronic storage medium associated with the second processing system such that the stored data is correlated to the unique identifier of the medical device.
