Abstract

The invention provides method for organizing the disinfection of one or more items contaminated with biological agent(s) comprising (a) attaching a radio-frequency ID (RFID) tag to an item(s) to be disinfected; exposing the item(s) of (a) to a disinfecting means for a period sufficient to disinfect the item; and (c) obtaining a signal from the tagged item when disinfection is complete thereby organizing the disinfection of one or more items.

Claims (31)

1. A device, comprising:

an ultraviolet light sensor;

a fluid sensor;

a timer; and

circuitry to activate the timer, wherein the circuitry is configured to:

start tracking a first duration upon receipt of a unique signal from the ultraviolet light sensor; and

start tracking a second duration upon receipt of a different unique signal from the fluid sensor.

2. The device of claim 1 , further comprising a changeable display and other circuitry to alter the changeable display upon receipt of either the unique signal or the different unique signal.

3. The device of claim 2 , wherein the other circuitry alters the changeable display to indicate a disinfection status of the device.

4. The device of claim 2 , wherein the other circuitry further alters the changeable display upon the first duration or the second duration reaching a predetermined amount of time.

5. The device of claim 4 , wherein the predetermined amount of time is approximately 24 hours or longer.

6. The device of claim 2 , further comprising additional circuitry to alter the changeable display after receiving a movement signal that indicates movement of the device.

7. The device of claim 6 , wherein the movement signal indicates the device crossing a chokepoint.

8. The device of claim 1 , wherein the device is a medical device or medical equipment.

9. The device of claim 1 , further comprising a wireless communication transmitter configured to send, upon receipt of either the unique signal or the different unique signal, a status signal to an external database indicating the device has been exposed to a disinfectant.

10. A system, comprising:

an ultraviolet light sensor;

a fluid sensor;

a timer; and

circuitry to activate the timer, wherein the circuitry is configured to:

start tracking a first duration upon receipt of a unique signal from the ultraviolet light sensor; and

start tracking a second duration upon receipt of a different unique signal from the fluid sensor.

11. The system of claim 10 , further comprising a portable apparatus configured to facilitate disinfection of a room.

12. The system of claim 11 , wherein the portable apparatus comprises a chemical disinfectant source.

13. The system of claim 11 , wherein the portable apparatus comprises an ultraviolet light lamp arranged to project light into an ambient of the apparatus.

14. The system of claim 11 , wherein the ultraviolet light sensor, the fluid sensor, the timer and the circuitry are arranged in a device separate from the portable apparatus.

15. The system of claim 14 , wherein the plurality of wireless communication tags are respectively attached to discrete medical devices and/or discrete pieces of medical equipment.

16. The system of claim 14 , wherein the plurality of wireless communication tags are attached to surfaces that are fixedly arranged in a room or area.

17. The system of claim 10 , further comprising a changeable display and other circuitry to alter the changeable display upon receipt of either the unique signal or the different unique signal.

18. The system of claim 10 , further comprising a wireless communication transmitter configured to send, upon receipt of either the unique signal or the different unique signal, a status signal to an external database indicating disinfection is complete.

19. The system of claim 10 , further comprising a plurality of wireless communication tags each having a changeable display and circuitry to alter their respective changeable display upon receipt of a disinfection status signal.
