Abstract

An electronic hand hygiene compliance system and award indicator that provides realtime reporting of the percent number of hand hygiene events against a programmed target number of hand hygiene events for a given functional area over a given period of time, yielding hand hygiene compliance. The system keeps up to date compliance for an established group interval until the data is written over by compliance data for the same group interval the following day. In addition, a random hand hygiene event can be identified for a given functional area during a given period of time to trigger an alarm for encouraging hand hygiene activity for a given dispenser or group of dispensers.

6. The hygiene compliance monitoring system of claim 5, wherein said keypad allows the display to be adjusted from no display to information regarding hand hygiene compliance data.

7. The hygiene compliance monitoring system of claim 1 further comprising:

an award indicator; and

a second controller associated with a second memory unit, said second controller being associated with said controller and providing a random event over a preselected reward time period, wherein said random event triggers said award indicator and can only happen once per said shift time interval.

8. The hygiene compliance monitoring system of claim 1, wherein said the number of memory banks are equal to the number of shift time intervals.

9. The hygiene compliance monitoring system of claim 1, wherein said target value is provided as a function of time.

10. The hygiene compliance monitoring system of claim 1, wherein said target value is set to a fixed number.

11. The hygiene compliance monitoring system of claim 1, further comprising a transceiver in communication with said controller that relays said actual hand hygiene events to other dispensers, receives other dispenser hygiene event data from said other dispensers, and sums the actual hand hygiene events and the other dispenser hygiene event data.

12. The hygiene compliance monitoring system of claim 11, wherein the target value corresponds to the sum of said dispenser target value and other dispensers target data.

13. The hygiene compliance monitoring system of claim 12, wherein each dispenser has an award indicator and a second controller associated with a second memory unit, said second controller is also associated with said controller and provides a random event over a preselected reward time period, wherein said random event triggers at least one of said award indicators and can only happen once per said shift time interval.

14. A hygiene compliance monitoring system for a functional grouping of dispensers wherein said functional grouping of dispensers includes more than one dispenser maintaining material to be dispensed, said hygiene compliance monitor comprising:

a dispenser controller that is coupled to an actuator of each dispenser within said functional grouping of dispensers, wherein said actuator initiates the dispensation of material from the dispenser when actuated;

a data transmission unit adapted to be coupled to said dispenser controller of each dispenser within said functional grouping of dispensers, said data transmission unit including a data collection memory unit and an internal clock in synchronization with the other dispensers of said functional grouping of dispensers, said memory unit having at least one memory bank for receiving data, said data transmission unit generating a series of successive shift time intervals wherein said shift time intervals are periods to which said at least one memory bank stores data from said internal clock, said shift time intervals being repeated in a sequence, and each of said at least one memory bank is deleted at the start of each said shift time interval; and

at least one data acquisition unit configured to set said clock and being further configured to receive at least one piece of data of said at least one actuation.

15. The hygiene compliance monitoring system of claim 14 wherein said controller is programmed with a target value of hand hygiene events, and said data is compared to said target value.

16. The hygiene compliance monitor of claim 14, wherein there is only one said data acquisition unit.
