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.

Claims

1. A hygiene compliance monitor 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, and wherein said controller is programmed with a target value of hand hygiene events;

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.

2. The hygiene compliance monitor system of claim 1, wherein said data acquisition unit has a display and a keypad.

3. The hygiene compliance monitor system of claim 2, wherein the dispenser includes a manager'"'"'s key to enable operation of said keypad and said display.

4. The hygiene compliance monitor system of claim 3, wherein said manager'"'"'s key is a personal identification number that can be entered on said keypad.

5. The hygiene compliance monitor system of claim 4, wherein said keypad allows the display to be adjusted from no display to information regarding hand hygiene compliance data.

6. The hygiene compliance monitor system of claim 1 further comprising an award indicator, a second controller associated with a second memory unit, said second controller being also 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.

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

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

9. The hygiene compliance monitor system of claim 1, further comprising a transceiver in communication with said controller, such that said transceiver relays said actuation to other dispensers, and receives other dispenser actuations, and wherein said dispenser controller sums the data and the other dispenser hygiene event data.

10. The hygiene compliance monitor system of claim 9, wherein the target value corresponds to the sum of said dispenser target value and other dispensers target data.

11. The hygiene compliance monitor system of claim 10, 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.

12. A method of hygiene compliance monitoring comprising:

a. providing a plurality of data transmission units each maintained by a dispenser, said dispenser including an actuator to initiate the dispensation of material from a refill container and a plurality of memory banks, wherein said data transmission unit;

stores a target value of dispensations;

generates a plurality of shift time intervals of a predetermined duration that repeat in a sequence, wherein each said shift time interval corresponds to each said memory bank;

clears the memory bank at the beginning of each said shift time interval;

monitors the engagement of said actuator; and

stores the number of engagements for each shift time interval into each memory bank; and

b. providing a data acquisition unit having a display and keypad, said data acquisition unit configured to communicate with said data transmission unit, and wherein said data transmission unit transfers the number of engagements and associated shift time intervals to the display of the data acquisition unit.

13. A hygiene compliance monitor for a functional grouping of dispensers maintaining material to be dispensed, said hygiene compliance monitor comprising:

a dispenser controller that is coupled to an actuator of each dispenser to initiate the dispensation of material from the dispenser when said actuator is actuated;

said each dispenser having a data transmission unit adapted to be coupled to said dispenser controller, said data transmission unit including a data collection memory unit and an internal clock in synchronization with the other dispensers, said memory unit having more than one memory bank for receiving data, said data transmission unit generating a series of successive shift time intervals that are periods to which said memory banks store data from said internal clock, said shift time intervals being repeated in a sequence, and each said 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, wherein said data is compared to a target value of hand hygiene events.

14. The hygiene compliance monitor of claim 13, wherein there is only one said data acquisition unit.

15. The hygiene compliance monitor of claim 14, wherein the one said data acquisition unit is affixed to one of the dispensers of the functional grouping.

16. The hygiene compliance monitor of claim 13, wherein the one said data acquisition unit is contained within a computer.
