Abstract

A system for monitoring and improving hygiene compliance in a caregiver setting is provided. The system includes a plurality of hand cleansing dispensers with sensors coupled thereto to detect usage of the dispenser and the identity of the personnel using the dispenser. Usage of the dispenser affects the personnel'"'"'s hygiene compliance. Indicators are coupled to or integral with the dispensers to output a real-time indication of the hygiene compliance of the personnel. As time progresses since the last detected handwashing event, the indicators can reflect the real-time degradation of hygiene compliance to keep the personnel well-informed of their compliance.

Claims

1. A method of monitoring hygiene compliance within a hygiene tracking environment, the method comprising:

(a) associating at least one indicator with a dispenser disposed within the hygiene tracking environment, wherein the dispenser is configured to facilitate hand-cleansing;

(b) sensing a physical presence of a person proximate the dispenser;

(c) in response to sensing the physical presence of the person proximate the dispenser, determining a hygiene compliance status associated with the person, wherein the hygiene compliance status indicates hygiene compliance or hygiene non-compliance;

(d) indicating the hygiene compliance status via the at least one indicator;

(e) sensing activation of the dispenser by the person;

(f) in response to sensing activation of the dispenser by the person, updating the hygiene compliance status associated with the person; and

(g) indicating the updated hygiene compliance status via the at least one indicator.

2. The method of claim 1, further comprising:

updating the at least one indicator based at least in part on a time elapsed since a previous activation of the dispenser.

3. The method of claim 1, further comprising:

changing a visual characteristic of the at least one indicator progressively based at least in part on a time elapsed since a previous activation of the dispenser.

4. The method of claim 1, further comprising:

(a) associating a personnel tag with the person; and

(b) sensing the personnel tag to sense the physical presence of the person proximate the dispenser.

5. The method of claim 1, further comprising:

(a) associating a dispenser tag with the dispenser;

(b) sensing the dispenser tag to determine the dispenser is within the hygiene tracking environment.

6. A method of monitoring hygiene compliance within a hygiene tracking environment, the method comprising:

(a) associating at least one indicator with a dispenser disposed within the hygiene tracking environment, wherein the dispenser is configured to facilitate hand-cleansing;

(b) sensing a physical presence of a person proximate the dispenser;

(c) determining whether the person is associated with a personnel tag;

(d) in response to determining the person is not associated with a personnel tag, providing instructions to the person to commence a hygiene compliance sequence via the at least one indicator;

(e) in response to determining the person is associated with a personnel tag, collecting a hygiene compliance status associated with the person, wherein the hygiene compliance status indicates hygiene compliance or hygiene non-compliance; and

(f) in response to the hygiene compliance status indicating hygiene non-compliance;

providing instructions to the person to commence the hygiene compliance sequence via the at least one indicator;

(ii) sensing activation of the dispenser by the person; and

(iii) in response to sensing activation of the dispenser by the person, updating the hygiene compliance status associated with the person to indicate hygiene compliance.

7. The method of claim 6, further comprising:

in response to the hygiene compliance status indicating hygiene non-compliance, indicating hygiene non-compliance via the at least one indicator.

8. The method of claim 7, further comprising:

in response to updating the hygiene compliance status associated with the person to indicate hygiene compliance, indicating the updated hygiene compliance status via the at least one indicator.

9. The method of claim 7, further comprising:

updating the at least one indicator based at least in part on a time elapsed since a previous activation of the dispenser.

10. The method of claim 7, further comprising:

changing a visual characteristic of the at least one indicator progressively based at least in part on a time elapsed since a previous activation of the dispenser.

11. The method claim 6, further comprising:

in response to sensing activation of the dispenser by the person, displaying a timer via the at least one indicator.

12. A system for monitoring hygiene compliance of a person desired to be tracked within a hygiene tracking environment, the system comprising:

(a) a dispenser configured to dispense a hand-cleansing product;

(b) a dispenser sensor configured to sense an activation of the dispenser and send a signal of the activation to affect a hygiene compliance status of the person;

(c) an indicator at the dispenser configured to controllably indicate hygiene compliance and non-compliance of the person; and

(d) a controller communicatively coupled to the dispenser sensor and the indicator and programmed to actuate the indicator based at least upon the hygiene compliance status of the person.

13. The system of claim 12, wherein the controller is programmed to actuate the indicator based at least upon the dispenser sensor sensing an activation of the dispenser.

14. The system of claim 12, wherein the controller is programmed to actuate the indicator based at least upon a time elapsing since a previous activation of the dispenser.

15. The system of claim 12, wherein the indicator includes a visual indicator.

16. The system of claim 15, where the controller is programmed to progressively alter the visual indicator as time elapses since the previous activation of the dispenser.

17. The system of claim 15, wherein the visual indicator includes a plurality of lights, wherein the controller is programmed to reduce the number of lights that are illuminated based on the time elapsing since the previous activation of the dispenser.

18. The system of claim 15, wherein the visual indicator includes an illuminated display, wherein the controller is programmed to change a color of the illuminated display based on the time elapsing since the previous activation of the dispenser.

19. The system of claim 12, wherein the controller is mounted to a local device system separate from the dispenser.

20. The system of claim 12, wherein the controller is mounted to an off-board control system separate from the dispenser.
