Abstract

A method and apparatus are disclosed for helping to assure the washing of hands. An easily identifiable substance is provided which can be removed by washing, and a marking mechanism is coupled to the easily identifiable substance. A hand of a person is then marked with the easily identifiable substance when the marking mechanism is triggered. In one embodiment, a flush mechanism of a toilet or urinal is equipped with the marking mechanism, and the marking mechanism is triggered when a person flushes the toilet or urinal. In another embodiment, a door handle is equipped with the marking mechanism, and the marking mechanism is triggered when a person uses the door handle.

Claims

1. A method for helping to assure the washing of hands, comprising:

providing an easily identifiable substance which can be removed by washing;

providing a marking mechanism coupled to the easily identifiable substance and physically connected to an actuating member that is associated with an event that requires washing of hands; and

marking a hand of a person with the easily identifiable substance when the marking mechanism is triggered upon the hand operating the actuating member.

2. The method of claim 1, wherein:

providing a marking mechanism comprises equipping a flush mechanism of a toilet or urinal with the marking mechanism; and

the marking mechanism is triggered when a person flushes the toilet or urinal.

3. The method of claim 1, wherein:

providing a marking mechanism comprises equipping a door handle with the marking mechanism; and

the marking mechanism is triggered when a person uses the door handle.

4. The method of claim 1, wherein:

providing a marking mechanism comprises providing a mechanical trigger; and

marking the hand occurs when the mechanical trigger is actuated.

5. The method of claim 4, wherein the mechanical trigger is covered with an absorbent material which contains the easily identifiable substance.

6. The method of claim 4, wherein an absorbent material which contains the easily identifiable substance is formed integral with the mechanical trigger.

7. The method of claim 4, wherein further comprising finger guides are associated with the marking mechanism.

8. The method of claim 4, wherein the mechanical trigger comprises a compressible bulb.

9. The method of claim 1, wherein the easily identifiable substance is selected from the group consisting of paint, dye, pigment, chalk and stain.

10. An apparatus for helping to assure the washing of hands, comprising:

an easily identifiable substance which can be removed by washing; and

a marking mechanism coupled to receive the easily identifiable substance, the marking mechanism physically connected with an actuating member that is associated with an event that requires washing of hands, and operable to mark a hand of a person with the easily identifiable substance when the marking mechanism is triggered upon the hand operating the actuating mechanism.

11. The apparatus of claim 10, wherein the actuating member comprises a flush mechanism of a toilet or urinal and to be triggered when a person flushes the toilet or urinal.

12. The apparatus of claim 10, wherein the marking mechanism is formed to be coupled to a door handle which provides a portion of the actuating member and to be triggered when a person uses the door handle.

13. The apparatus of claim 10, wherein the marking mechanism comprises a mechanical trigger operable to mark the hand when the mechanical trigger is actuated.

14. The apparatus of claim 13, further comprising finger guides associated with the marking mechanism.

15. The apparatus of claim 13, further comprising an absorbent material covering the mechanical trigger, the absorbent material containing the easily identifiable substance.

16. The apparatus of claim 15, further comprising a container operable to hold the easily identifiable substance and coupled to provide the easily identifiable substance to the absorbent material.

17. The apparatus of claim 13, wherein the mechanical trigger comprises an absorbent material formed integral therewith, the absorbent material containing the easily identifiable substance.

18. The apparatus of claim 17, further comprising a container operable to hold the easily identifiable substance and coupled to provide the easily identifiable substance to the absorbent material.

19. The apparatus of claim 13, wherein the mechanical trigger comprises a compressible bulb.

20. The apparatus of claim 10, wherein the easily identifiable substance is selected from the group consisting of paint, dye, pigment, chalk and stain.
