Abstract

Disclosed herein are different embodiments of a hand hygiene compliance system, beacon, wearable monitor and kit.

Claims

1. A self-contained beacon for use in a hand hygiene compliance system to interface with a plurality of wearable monitors in the implementation of an automated hand hygiene compliance protocol, the beacon comprising:

a mountable housing;

an integrated power source; and

a transmitter operatively coupled to the power source, the transmitter comprising two or more emitters operatively disposed and divergently angled relative to one another to emit respective transmission beams shaped to bisect a designated attendant travel path to intercept passage of the wearable monitors upon passage along the travel path, wherein the respective transmission beams are configured to overlap to form a combined transmission beam to be substantially uninterrupted at a level of the wearable monitor as the combined transmission beam bisects the path, the transmitter configured to transmit an encoded identifier via the two or more emitters to be received and processed by the wearable monitors upon passage along the travel path for implementation of the automated hand hygiene compliance protocol.

2. The self-contained beacon of claim 1, wherein the combined transmission beam defines a curtain-like beam having a longitudinal beam width along the path that is narrower than a bisecting beam width across the path.

3. The self-contained beacon of claim 1, wherein the integrated power source comprises an accessible battery module for receiving one or more replaceable batteries, and the housing comprises a ceiling mountable base and a removable cover for access to the battery module.

4. The self-contained beacon of claim 1, further comprising a motion sensor configured to detect, and activate the transmitter in response to, an incoming attendant along the path.

5. The self-contained beacon of claim 1, wherein the two or more emitters are configured to emit infra-red (IR) signals.

6. The self-contained beacon of claim 5, wherein the two or more emitters are configured to emit pulse coded signals including the encoded identifier.

7. The self-contained beacon of claim 6, wherein the encoded identifier includes at least one group identifier, with each group identifier being common to a number of beacons.

8. The self-contained beacon of claim 7, wherein the at least one group identifier includes a first group identifier identifying a monitored zone boundary or a second group identifier identifying a non-monitored zone.

9. The self-contained beacon of claim 6, wherein the encoded identifier indicates entry or exit from a monitored zone.

10. A hand hygiene compliance system, comprising a plurality of self-contained beacons, each to interface with a plurality of wearable monitors in the implementation of an automated hand hygiene compliance protocol, each beacon comprising a mountable housing;

an integrated power source; and

a transmitter operatively coupled to the power source, the transmitter comprising two or more emitters operatively disposed and divergently angled relative to one another to emit respective transmission beams shaped to bisect a designated attendant travel path to intercept passage of the wearable monitors upon passage along the travel path, wherein the respective transmission beams are configured to overlap to form a combined transmission beam, wherein the combined transmission beam is substantially uninterrupted at a level of the wearable monitors as the combined transmission beam bisects the travel path, the transmitter of each of the beacons being operable to transmit an encoded identifier via the two or more emitters to be received and processed by the wearable monitors upon passage along the travel path for implementation of the automated hand hygiene compliance protocol, wherein each of the beacons is independently operable from one another and thus selectively mountable or dismountable in adaptively reconfiguring the hand hygiene compliance system.

11. The system of claim 10, further comprising a plurality of the wearable monitors, each to be worn by an attendant in a facility and including a receiver to receive at least one encoded identifier from at least one of the beacons.

12. The system of claim 11, further comprising a plurality of dispensers operatively mountable within the facility, each of the dispensers comprising an integrated power source and a transmitter operatively coupled thereto to transmit a dispensing signal upon dispenser activation;

wherein the wearable monitors are configured to record a hand hygiene action upon receiving the dispensing signal and accordingly update a hand hygiene status stored on the wearable monitors in accordance with the automated hand hygiene compliance protocol.

13. The system of claim 12, wherein each of the dispensers is configured to encode a dispenser identifier in the dispensing signal.

14. The system of claim 13, wherein the dispenser identifier includes a group or type identifier and/or a unique dispenser identifier.

15. The system of claim 10, wherein the combined transmission beam defines a curtain-like beam having a longitudinal beam width along the path that is narrower than a bisecting beam width across the path.

16. The system of claim 15, wherein the integrated power source comprises an accessible battery module for receiving one or more replaceable batteries and wherein the housing comprises a ceiling mountable base and a removable cover removable in providing access to the battery module.

17. The system of claim 15, each beacon further comprising a motion sensor configured to detect, and activate the transmitter in response to, an incoming attendant along the path.

18. The system of claim 10, wherein the plurality of self-contained beacons comprises a plurality of the beacons which are substantially identical, wherein the two or more emitters are fixedly disposed to emit substantially identically shaped divergent combined transmission beams amenable to bisecting a range of attendant travel path widths such that any of the plurality of substantially identical beacons can be used indiscriminately to intercept passage of the wearable monitors across any of the attendant travel path widths.

19. The system of claim 18, wherein the two or more emitters are configured to emit IR signals.

20. The system of claim 19, wherein the two or more emitters are configured to emit pulse coded signals including the encoded identifier.

21. The system of claim 20, wherein the encoded identifier includes at least one group identifier, each group identifier being common to a number of the beacons.

22. The system of claim 21, wherein the at least one group identifier includes a first group identifier to identify a monitored zone or a second group identifier to identify a non-monitored zone.

23. The system of claim 20, wherein each wearable monitor is configured to issue a prompt in real time when receiving the encoded identifier indicating entry to or exit from a monitored zone without receiving the dispensing signal within a set period of time.

24. The system of claim 23, wherein the prompt is selectable and including vibration and/or sound.

25. The system of claim 23, wherein each wearable monitor is configured to disable the prompt either after receiving a dispensing signal from a dispenser or after a set period of time, whichever is sooner.

26. The system of claim 23, wherein the wearable monitors are configured to provide a number of counts or values representing:

A) the number of times a zone boundary is crossed without the need for a prompt, B) the number of times a zone boundary is crossed when a dispenser is activated in response to a prompt within a permitted time, and C) the number of times a dispenser is not operated in response to a prompt within the permitted time, wherein the system is configured to measure compliance ratios as (A+B)/(A+B+C).

27. A hand hygiene compliance kit comprising:

at least one self-contained beacon to interface with a plurality of wearable monitors in the implementation of an automated hand hygiene compliance protocol, the at least one self-contained beacon including;

a mountable housing;
