Abstract

A sanitization compliance monitoring system comprises care giver badges, patient bed beacons associated with patient beds, dispenser beacons associated with sanitization dispensers, and a central unit for wirelessly communicating with the badges.

Claims

1. A sanitization compliance monitoring system for a health care environment having patient beds, comprising:

badges wearable by persons, said badges having indicia representing a first-state indicating a sanitary compliant condition of the person, a second-state representing a cautionary state indicating the person'"'"'s contact with a first patient, and a third-state representing an unsanitary state indicating the person'"'"'s contact with a second patient after contact with, and different from, a first patient, said badges also having a wireless transmitter/receiver for communicating an identification signal unique to a single badge, and the current state of the badge;

patient bed beacons, each associated with a different respective patient bed, each bed beacon having a transmitter/receiver capable of wirelessly communicating with said badges;

dispenser beacons, each associated with a sanitization dispenser, and having a transmitter/receiver capable of wirelessly communicating with said badges; and

wherein a badge in said first-state changes to said second-state when located in a certain proximity to a patient bed beacon, and transmits a status change signal indicating such first-to-second-state change to the patient bed beacon with the badge identification signal;

wherein a badge in said second-state changes to said third-state when located in a certain proximity to a patient bed beacon different from the patient bed beacon which caused the badge to change from the first-state to the second-state, and transmits a status signal indicating such second-to-third-state change to the patient bed beacon with the badge identification signal, and

wherein a dispenser beacon causes a badge to change from the second-state or third-state to the first-state when the person has performed a sanitization procedure at a sanitization dispenser beacon.

2. The system according to claim 1, further including a central unit for wirelessly communication with patient bed beacons, and

wherein a patient bed beacon transmits the identification signal of the badge, and the current state of the badge, to the central unit, in response to the badge coming into a certain proximity with a patient bed beacon.

3. The system according to claim 1, further including a central unit for wirelessly communication with patient bed beacons, and

wherein a dispenser beacon transmits the identification signal of the badge, and the current state of the badge, to the central unit, in response to the badge coming into proximity with a dispenser beacon.

4. The system of claim 1, wherein the badges'"'"' indicia comprise three different color lights respectively representing the first-, second-, and third-states.

5. The system of claim 1, wherein the badges include an audio beeper in response to the dispenser beacon causing a change in the badge state from a second- or third-state to a first-state.

6. The system of claim 1, wherein, in response to a badge coming in close proximity to a dispenser beacon, the badge transmitter/receiver and the dispenser transmitter/receiver increase their respective transmitter/receiver ranges to permit communication over a wider communication-range, and wherein the respective badge and dispenser beacon lock communication to the exclusion of other badges and dispenser beacons, until communication between the badge and dispenser beacon is complete.

7. The system of claim 1, wherein, in response to a badge coming in close proximity to a bed beacon, the badge transmitter/receiver and the bed beacon transmitter/receiver increase their respective transmitter/receiver ranges to permit communication over a wider communication-range, and wherein the respective badge and bed beacon lock communication to the exclusion of other badges and bed beacons, until communication between the badge and bed beacon is complete.

8. The system of claim 1, wherein a badge in a second-state changes to the third-state if the badge leaves the certain proximity to a patient bed and remains out of that proximity for a certain time period and re-enters that certain proximity after the certain time period.

9. The system of claim 1, wherein a badge in the first-state changes to the second-state after a certain time period has elapsed without the badge-wearer performing a sanitization procedure.

10. The system of claim 1, wherein a badge in the second-state changes to the third-state after a certain time period has elapsed without the badge-wearer performing a sanitization procedure.

11. A method for monitoring sanitization compliance for a health care environment having patient beds, comprising:

providing badges wearable by persons, said badges having indicia representing a first-state indicating a sanitary compliant condition of the person, a second-state representing a cautionary state indicating the person'"'"'s contact with a first patient, and a third-state representing an unsanitary state indicating the person'"'"'s contact with a second patient after contact with, and different from, a first patient, said badges also having a wireless transmitter/receiver for communicating an identification signal unique to a single badge, and the current state of the badge;

providing patient bed beacons, each associated with a different respective patient bed, each bed beacon capable of wirelessly communicating with said badges;

providing dispenser beacons, each associated with a sanitization dispenser, and having a transmitter/receiver capable of wirelessly communicating with said badges;

changing the state of a badge from said first-state to said second-state when located in a certain proximity to a patient bed beacon, and transmitting a status change signal indicating such first-to-second-state change to the patient bed beacon with the badge identification signal;

changing the state of a badge from said second-state to said third-state when located in a certain proximity to a patient bed beacon different from the patient bed beacon which caused the badge to change from the first-state to the second-state, and transmitting a status signal indicating such second-to-third-state change to the patient bed beacon with the badge identification signal;

changing the status of a badge from the second-state or third-state to the first-state when the person has performed a sanitization procedure at a sanitization dispenser.

12. The method according to claim 11, including wirelessly communicating with a central unit, and

wherein a patient bed beacon transmits the identification signal of the badge, and the current state of the badge, to the central unit, in response to the badge coming within a certain proximity with a patient bed beacon.

13. The method according to claim 11, including wirelessly communicating with a central unit, and

wherein a dispenser beacon transmits the identification signal of the badge, and the current state of the badge, to the central unit, in response to the badge coming within a certain proximity with a dispenser beacon.

14. The method of claim 11, comprising illuminating badges'"'"' indicia with three different color lights respectively representing the first-, second-, and third-states.

15. The method of claim 11, comprising generating an audio signal by a badge in response to the dispenser beacon causing a change in the badge state from a second- or third-state to a first-state.

16. The method of claim 11, wherein, in response to a badge coming in a certain proximity to a dispenser beacon, the badge transmitter/receiver and the dispenser transmitter/receiver increase their respective transmitter/receiver ranges to permit communication over a wider communication-range, and wherein the respective badge and dispenser beacon lock communication to the exclusion of other badges and dispenser beacons, until communication between the badge and dispenser beacon is complete.

17. The method of claim 11, wherein, in response to a badge coming in close proximity to a bed beacon, the badge transmitter/receiver and the bed beacon transmitter/receiver increase their respective transmitter/receiver ranges to permit communication over a wider communication-range, and wherein the respective badge and bed beacon lock communication to the exclusion of other badges and bed beacons, until communication between the badge and bed beacon is complete.

18. The method of claim 11, wherein a badge in a second-state changes to the third-state if the badge leaves the certain proximity to a patient bed and remains out of that proximity for a certain time period and re-enters that certain proximity after the certain time period.

19. The method of claim 11, wherein a badge in the first-state changes to the second-state after a certain time period has elapsed without the badge-wearer performing a sanitization procedure.

20. The method of claim 11, wherein a badge in the second-state changes to the third-state after a certain time period has elapsed without the badge-wearer performing a sanitization procedure.
