Abstract

In some embodiments, a hand washing compliance system includes a primary soap dispenser adapted to be located near an entrance to a room, the primary soap dispenser comprising a motion sensor configured to detect passage of an individual through the room entrance, a soap dispensation sensor configured to detect dispensation of soap from the primary soap dispenser, and a communication device configured to enable communication with other soap dispensers, and a secondary soap dispenser adapted to be located inside of the room, the secondary soap dispenser comprising a soap dispensation sensor configured to detect dispensation of soap from the secondary soap dispenser, a communication device configured to enable communication with other soap dispensers, and a warning indicator configured to generate an alert that encourages individuals entering the room to wash their hands.

Claims

1. A hand washing compliance system comprising:

a primary soap dispenser adapted to be located near an entrance to a room, the primary soap dispenser comprising a motion sensor configured to detect passage of an individual through the entrance to the room, a soap dispensation sensor configured to detect dispensation of soap from the primary soap dispenser; and

a wireless transceiver configured to enable direct wireless communication with other soap dispensers; and

a secondary soap dispenser adapted to be located inside of the room, the secondary soap dispenser comprising a soap dispensation sensor configured to detect dispensation of soap from the secondary soap dispenser, a wireless transceiver configured to enable direct wireless communication with other soap dispensers, and a warning indicator configured to generate an alert that encourages individuals entering the room to wash their hands.

2. The system of claim 1, wherein the primary soap dispenser is configured to determine whether or not an individual who entered the room washed his or her hands immediately prior to entry.

3. The system of claim 2, wherein the primary soap dispenser determines whether or not the individual washed his or her hands immediately prior to entry by determining whether or not soap was dispensed from the primary soap dispenser within a predetermined time period prior to the primary soap dispenser detecting passage of the individual through the entrance to the room.

4. The system of claim 3, wherein the primary soap dispenser is further configured to transmit a command to the secondary soap dispenser to generate a first alert if the individual did not wash his or her hands immediately prior to entry and no communication indicative of soap dispensation is received from the secondary soap dispenser within a first compliance time period initiated after detecting passage of the individual through the room entrance.

5. The system of claim 4, wherein the secondary soap dispenser comprises a light and wherein the secondary soap dispenser is configured to activate a visual alert with the light in response to receiving the command to generate a first alert.

6. The system of claim 5, wherein the primary soap dispenser is further configured to transmit a command to the secondary soap dispenser to generate a second alert if no communication indicative of soap dispensation is received from the secondary soap dispenser within a second compliance time period initiated after transmission of the command to generate a first alert.

7. The system of claim 6, wherein the secondary soap dispenser comprises a speaker and wherein the secondary soap dispenser is configured to activate an audible alert with the speaker in response to receiving the command to generate a second alert.

8. The system of claim 1, wherein the primary soap dispenser comprises two motion sensors that enable the primary soap dispenser to distinguish between room entry and room exit.

9. The system of claim 1, wherein the system includes multiple secondary soap dispensers adapted to be located inside of the room, each secondary soap dispenser comprising a soap dispensation sensor configured to detect dispensation of soap from the secondary soap dispenser, a wireless transceiver configured to enable direct wireless communication with other soap dispensers, and a warning indicator configured to generate an alert that encourages individual entering the room to wash their hands.
