Abstract

New forms of self-sterilizing and antiseptic surfaces are provided. In some embodiments, a handled surface or GUI comprises internal hardware performing a heavy rinse of the handled surface triggered by an end-of-use function. In other embodiments, pressure on a handled surface instead causes the surface to uniformly exude water and other antiseptic compositions from a refillable source.

First claim

I claim:

1. An antiseptic device comprising:
an outer surface on a first side of said device, wherein said outer surface comprises at least one port connected with antiseptic hardware;
wherein said antiseptic hardware comprises a reservoir and at least one movable panel, configured to move toward a second, inward-facing side of said device in reaction to pressure against said outer surface of said device; and
wherein said antiseptic hardware comprises at least one channel, different from said at least one port, wherein said at least one channel comprises liquid-proof or liquid-resistant fluid-guiding walls comprising curved angles different from angles of walls of any of said at least one port and configured to guide an antiseptic fluid to each of said at least one port and from said reservoir.

2. The antiseptic device of claim 1 , comprising a filling port at or about the top of said antiseptic device.

3. The antiseptic device of claim 1 , wherein said reservoir comprises a spongy material configured to absorb, distribute and exude said antiseptic fluid.

4. The antiseptic device of claim 3 , wherein said spongy material is configured to exude said antiseptic fluid through said at least one port when compressed.

5. The antiseptic device of claim 4 , wherein said spongy material abuts and is attached to said movable panel, and is configured to be compressed by said movable panel when said outer contact surface is touched by a user.

6. The antiseptic device of claim 5 , wherein said spongy material abuts said at least one channel configured to guide an antiseptic fluid to each of said at least one port.

7. The antiseptic device of claim 6 , wherein said at least one port comprise at least part of a plurality of sloped interior channels.

8. The antiseptic device of claim 7 , wherein said at least one sloped interior channel are partially comprised in and/or at least partially abutting the bottom of the interior of at least one of said at least one port.

9. A self-cleaning user interface device, comprising:
a user-actuable moving part, wherein said user-actuable moving part is configured for placement in at least an on position and an off position;
a reservoir connected with said user-actuable moving part;
at least one port positioned above a handled surface of said user-actuable moving part; and
a control system comprising sensors configured to sense when said user-actuable moving part is placed in said on position or said off position;
wherein said control system is configured to release water or other antiseptic fluid, covering said handled surface, upon said sensors sensing that said user-actuatable moving part has been placed in said off position.

10. The self-cleaning user interface device of claim 9 , wherein said user-actuable moving part is configured to load and pressurize said reservoir, and wherein said reservoir is configured to hold water or another antiseptic fluid when placed in said on position.

11. The self-cleaning user interface device of claim 9 , wherein said user-actuable moving part is configured to release water or other antiseptic fluid, covering said handled surface, upon being placed in said off position, after a delay.

12. The self-cleaning user interface device of claim 9 , wherein said control system comprises pumps configured to pump antiseptic fluid out of said at least one port.

13. A method for providing an antiseptic surface for an object, comprising the following steps:
attaching an antiseptic device to said object, wherein said device comprises an outer surface on a first side of said device, wherein said outer surface comprises at least one port connected with antiseptic hardware;
wherein said antiseptic hardware comprises a reservoir and at least one movable panel, configured to move toward a second, inward-facing side of said device in reaction to pressure against said contact surface of said device; and
wherein said antiseptic hardware comprises at least one channel, different from said at least one port, wherein said at least one channel comprises liquid-proof or liquid-resistant fluid-guiding walls comprising curved angles different from angles of walls of any of said at least one port and configured to guide an antiseptic fluid to each of said at least one port and from said reservoir.

14. The method for providing an antiseptic surface for an object of claim 13 , comprising the following additional step:
touching said outer contact surface and moving said movable panel, causing said antiseptic fluid to escape from said at least one port and cover said outer contact surface.

15. The method for providing an antiseptic surface for an object of claim 13 , comprising the following additional step:
refilling said reservoir with said antiseptic fluid.
