Abstract

The invention relates generally to the field of hand sanitation, and particularly to a door opening system that restricts the movement of people through a doorway or threshold to those that have activated a hand sanitizer dispensing unit.

Claims

1. A door opening system comprising:

a) a hand sanitizer dispensing unit that releases a hand sanitizer upon activation;

b) a door with a door opening or locking device; and

c) an electrical, mechanical, or wireless signal connection between said hand sanitizer dispensing unit and said opening or locking device;

wherein said door opening or locking device is adapted to be activated to allow movement of said door upon activation of said hand sanitizer dispensing unit.

2. The system of claim 1, wherein said hand sanitizer comprises a chemical or radiological sanitizer.

3. The system of claim 2, wherein said chemical sanitizer is selected from the group consisting of triclosan, ethanol, isopropanol, n-propanol, povidone-iodide, chlorhexidine gluconate, octenidine, chloroxylenol, hexachlorophene, alkyl benzalkonium chloride, benzethonium chloride, cetrimide, and cetylpyridium chloride.

4. The system of claim 2, wherein said chemical sanitizer is ethanol.

5. The system of claim 2, wherein said chemical sanitizer is triclosan.

6. The system of claim 2, wherein said chemical hand sanitizer is applied with a towel, towelette, or hand wipe.

7. The system of claim 2, wherein said radiological sanitizer is ultraviolet light.

8. The system of claim 1, wherein said door is an elevator door.

9. The system of claim 1, wherein said wireless signal connection comprises a radio or infrared connection.

10. The system of claim 1, wherein said door opening or locking device further comprises a manual override mechanism, wherein use of said mechanism allows movement of the door independent of said activation of said hand sanitizer dispensing unit.

11. The system of claim 1, wherein said hand sanitizer dispensing unit is mounted on said door.

12. The system of claim 1 further comprising instructions for the use of said system.

13. The system of claim 1, wherein said door is contained in a hospital, medical facility, nursing home, school, daycare center, library, museum, public meeting or working space, retail store, grocery store, restaurant, cafeteria, kitchen, food production or processing facility, public transportation station, or public transit vehicle.

14. The system of claim 1, wherein said door is contained in a hospital.

16. The system of claim 1, wherein said door is contained in an airport, train station, subway station, or bus station.

17. The system of claim 1, wherein said door is contained in an airplane, a train, a subway train, a bus, or boat.

18. The system of claim 17, wherein said boat is a cruise ship.

19. The system of claim 1, wherein said door separates medical caregivers from medical patients.

20. The system of claim 19, wherein said caregivers comprise physicians, nurses, medical technicians, pharmacists, or medical students.

21. A method of reducing microbial infection comprising activation of a hand sanitizer dispensing unit mounted on or proximal to a door with a door opening or locking device, wherein said activation allows movement of said door.
