Abstract

Apparatus and systems for use in cleaning the gap or crevice under a person'"'"'s fingernails. The inventive apparatus includes one or more finger alignment guides which assist in maintaining the fingers in a desired orientation and a mechanical scrubber, such as a brush, individual strands, or a set of water jets, which are able to mechanically remove dirt and other foreign debris from the gap under a person'"'"'s fingernails. The cleaning system further includes a cleaning liquid, such as an aqueous solution or other solvent-based liquid or solution that is able to assist the mechanical scrubber in removing foreign debris from under the fingernails. The alignment guide may be stationary while movement of the mechanical scrubber provides the scrubbing action. The mechanical scrubber will typically be driven by a motor or pump. Alternatively the fingers may move relative to the scrubber in order to provide the scrubbing action.

Claims

1. A cleaning apparatus for cleaning the gap under at least one of a person'"'"'s fingernails comprising:

scrubbing means for removing foreign debris from the gap under at least one fingernail, said scrubbing means including at least one scrubbing component selected from the group consisting of bristles and strands which are configured so as to be capable of entering the gap under the at least one fingernail in order to remove foreign debris therefrom; and

finger alignment means for maintaining at least one fingernail in an orientation so as to facilitate entry of at least a portion of the scrubbing means into the gap under the at least one fingernail.

2. A cleaning apparatus as defined in claim 1, wherein the finger alignment means includes at least one finger alignment guide selected from the group consisting of finger alignment tunnel, finger alignment trough, and finger alignment stops.

3. A cleaning apparatus as defined in claim 1, wherein the finger alignment means includes a substantially regular surface selected from the group consisting of planar and curved surfaces.

4. A cleaning apparatus as defined in claim 3, wherein desired alignment and restraint of movement between at least one finger and the scrubbing means is maintained by means of friction between the substantially regular surface and the at least one finger.

5. A cleaning apparatus as defined in claim 3, wherein the substantially regular surface is substantially devoid of friction so as to permit slippage and movement of at least one finger relative to the substantially regular surface.

6. A cleaning apparatus as defined in claim 1, wherein the scrubbing means comprises a brush that includes bristles, wherein at least some of the bristles are able to enter into the gap under the at least one fingernail in order to mechanically remove foreign debris therefrom.

7. A cleaning apparatus as defined in claim 6, wherein the bristles include bristle tips that define a curve.

8. A cleaning apparatus as defined in claim 6, wherein the bristle include bristle tips that define a substantially straight edge.

9. A cleaning apparatus as defined in claim 1, wherein the scrubbing means further includes a liquid brush capable of emitting a stream of liquid with sufficient force so as to remove foreign debris from the gap under a person'"'"'s fingernails.

10. A cleaning apparatus as defined in claim 1, wherein the scrubbing means comprises one or more cleaning strands.

11. A cleaning apparatus as defined in claim 1, further including drive means for causing relative movement between the scrubbing means and the at least one fingernail being cleaned.

12. A cleaning apparatus as defined in claim 11, wherein the at least one fingernail remains substantially stationary and wherein the drive means causes the scrubbing means to move in relation to the at least one fingernail.

13. A cleaning apparatus as defined in claim 11, wherein the scrubbing means remain substantially stationary and wherein the drive means causes the finger alignment means to move relative to the scrubbing means so as to result in a scrubbing action that cleans debris from the gap under the at least one fingernail.

14. A cleaning apparatus as defined in claim 11, further including activation means for activating the drive means.

15. A cleaning apparatus as defined in claim 1, wherein manual movement of the at least one fingernail relative to the scrubbing means facilitates removal of debris from the gap under at least one fingernail.

16. A cleaning apparatus as defined in claim 1, further including a cleaning liquid that assists the scrubbing means in removing debris from under the at least one fingernail.

17. A cleaning apparatus as defined in claim 16, wherein the cleaning liquid is antipathogenic and able to substantially sterilize the at least one fingernail and surrounding finger tissues.

18. A cleaning apparatus for cleaning the gap under at least one of a person'"'"'s fingernails comprising:

at least one brush that remains substantially stationary during cleaning of one or more fingernails; and

a finger alignment guide which allows at least one finger to move relative to the scrubbing means so as to facilitate entry of at least a portion of the brush into the gap under the at least one fingernail in order to effect cleaning of the gap under the fingernail.

19. A cleaning apparatus as defined in claim 18, wherein the finger alignment guide is configured so as to prevent substantial slippage between at least one finger and the finger alignment guide, wherein the finger alignment means and the at least one finger move together relative to the brush.

20. A cleaning apparatus as defined in claim 18, wherein the finger alignment guide is configured to be substantially stationary in relation to the brush, wherein the finger alignment guide is sufficiently devoid of friction so as to permit slippage and movement of at least one finger relative to the finger alignment guide, thereby allowing at least one finger to move relative to the brush in order to effect cleaning of the gap under the fingernail.

21. A cleaning apparatus as defined in claim 18, further including a cleaning liquid that assists the brush in removing debris from under the at least one fingernail.

22. A cleaning apparatus as defined in claim 18, wherein the cleaning apparatus includes one single brush that is able to clean the gap under a plurality of fingernails.

23. A cleaning system for cleaning the gap under at least one of a person'"'"'s fingernails comprising:

a finger alignment guide that restrains movement of at least one finger during cleaning of the gap under the fingernail; and

at least one brush that is configured so as to move relative to the at least one finger and oriented so as to at least partially enter the gap under the at least one fingernail in order to effect cleaning thereof.
