Abstract

The present invention provides a hand sanitizer system that includes a proximity detector, a dispensing system and an alarm feature, and is operative to provide an indication corresponding to a person in proximity of the system failing to dispense antiseptic or other solution from the dispenser within a predetermined period of time after moving within a predetermined range of the detector.

Claims

1. A hand sanitization system comprising:

a sanitization unit having;

a proximity detector operatively connected to a housing, the proximity detector operative to determine proximity of a person within a predetermined range with respect to the sanitization unit;

a proximity sensor action counter operatively connected to the proximity detector, the proximity sensor action counter for counting each proximity indication from the proximity detector indicating when the person is within the predetermined range;

a sanitizer action counter operatively connected to a dispenser, the sanitizer action counter for counting each time the dispenser is activated;

an alarm operatively connected to the housing and being operative to provide an indication to the person, the indication corresponding to the person failing to dispense antiseptic solution from the dispenser within a predetermined period of time after moving within the predetermined range of the sanitization unit, wherein the predetermined period of time is adjustable; and

an alarm counter operatively connected to the alarm, the alarm counter for counting each time the alarm is activated; and

a replaceable antiseptic module comprising a reservoir of antiseptic solution and a battery operative to power one or more components of the sanitization unit or dispenser.

2. The system of claim 1, wherein the proximity detector is an infrared range finder.

3. The system of claim 1, wherein the indication is an audible indication.

4. The system of claim 1, wherein the alarm comprises a piezo-electric buzzer.

5. The system of claim 1, wherein the sanitization unit further comprises a low battery indicator.

6. The system of claim 1, wherein the sanitization unit further comprises a photo-sensor operative to determine ambient light in a vicinity of the unit.

7. The system of claim 6, wherein:

the indication is an audible indication; and

the sanitization unit is operative to adjust an audio level of the audible indication based, at least in part, on the ambient light level in the vicinity of the unit.

8. The system of claim 1, wherein the proximity detector has a Schmitt trigger operative to output a digital signal corresponding to a sensed distance of the person from the sanitization unit.

9. The system of claim 1, wherein the sanitization unit further comprises a microprocessor operative to receive an input from the proximity detector and from the dispenser and to provide an output to the alarm based, at least in part, on the inputs received.

10. The system of claim 1, further comprising a computer memory storing a database, the database comprising information corresponding to use of the sanitization unit.

11. The system of claim 10, wherein:

the sanitization unit is a first of multiple sanitization units; and

the multiple sanitization units provide information for populating the database.

12. A hand sanitization system comprising:

a proximity detector operatively connected to a sanitizer housing operative to determine proximity of a person with respect to the detector, wherein a range of the proximity detector is adjustable and wherein the sanitizer housing comprises a dispenser operative to dispense antiseptic solution and provide an output signal corresponding to dispensing of the antiseptic solution;

an alarm operatively connected to the sanitizer housing operative to provide an indication to the person, the indication corresponding to the person failing to dispense antiseptic solution from the dispenser within a predetermined period of time after moving within a predetermined range of the detector;

a proximity detector action counter operatively connected to the proximity detector, the proximity detector action counter for counting each proximity indication for the proximity detector indicating when the person is within the predetermined range;

a sanitizer action counter operatively connected to the dispenser for counting each time the dispenser is activated;

an alarm counter operatively connected to the alarm, the alarm counter for counting each time the alarm is activated; and

a replaceable antiseptic module comprising a reservoir of antiseptic solution and a battery operative to power one or more components of the sanitization unit or dispenser.

13. A method for monitoring hand sanitizer usage compliance, the method comprising:

determining whether a person is within a predetermined range of a sanitization unit via a proximity detector;

counting each proximity indication from the proximity detector indicating when the person is within the predetermined range via a proximity sensor action counter operatively connected to the proximity detector;

counting each time a dispenser is activated via a sanitizer action counter operatively connected to the dispenser;

providing an indication corresponding to the person failing to dispense antiseptic solution from the dispenser within a predetermined period of time after moving within the predetermined range of the sanitization unit via an alarm;

counting each time the alarm is activated via an alarm counter operatively connected to the alarm, wherein;

the predetermined period of time and the predetermined range are adjustable;

at least one processor is operatively connected to the proximity detector, the proximity sensor action counter, the sanitizer action counter, the alarm, and the alarm counter; and

one or more components of the sanitization unit or dispenser are powered by a battery included in a replaceable antiseptic module comprising a reservoir of antiseptic solution operatively connected to the sanitization unit.

14. The method of claim 13, wherein the at least one processor is operatively coupled to a wireless transmitter for transmitting data from each of the proximity sensor counter, the sanitizer action counter, and the alarm counter to a second device.

15. The method of claim 14, wherein the indication corresponding to the person failing to dispense antiseptic solution comprises a voice reminder.

16. The method of claim 15, wherein a volume of the voice reminder is adjustable.

17. The method of claim 16, wherein the volume of the voice reminder is automatically adjusted based on one or more of the group comprising a time of day, an ambient level of light, expiration of a time period, activation of a silence switch.

18. The method of claim 13, wherein the method further comprises:

receiving an indication of activation of a silence switch operatively coupled to the at least one processor; and

in response to receiving the indication of the activation of the silence switch, silencing the alarm upon a timer reaching the predetermined period of time.
