Abstract

An assembly structured to clean the head portion of a stethoscope comprising a housing including a path of travel along which the head portion passes during cleaning. A supply of cleaning fluid associated with a dispenser assembly is cooperatively disposed relative to an activating assembly. The activating assembly is operated in moveable engagement with the head portion, and activates the dispenser assembly when engaged by the head portion as it passes along the path of travel. The dispenser assembly delivers the cleaning fluid to an applicator assembly which distributes the cleaning fluid to the head portion and facilitates the cleaning thereof and removal of excess cleaning fluid there from. At least one disinfectant agent is dispersed within or comprises a portion of the housing and is formulated to be destructively effective against pathogenic bacteria, such as in the spore form, which is generally not affected by the cleaning fluid.

Claims

1. An assembly structured to clean a head portion of a stethoscope, said assembly comprising:

a housing including an entrance and an exit and a path of travel for the head portion extending therebetween,

said entrance and exit providing access to an interior of said housing,

a fluid supply structured to contain a cleaning fluid for dispensing into said interior of said housing,

an applicator disposed in said path of travel in engaging relation to the head portion,

a dispenser comprising at least two dispensing positions and operatively connected to said fluid supply, said dispensing positions being sufficiently longitudinal offset relative to one another to direct said cleaning fluid to different portions of said path of travel,

at least one disinfectant agent disposed in said housing in at least partially communicating relation with the head portion, and

said at least one disinfectant agent having a composition destructively effective against bacteria.

2. An assembly as recited in claim 1 wherein said composition of said at least one disinfectant agent is destructively effective against spore forms of at least clostridium difficile.

3. An assembly as recited in claim 1 wherein said at least one disinfectant agent comprises a portion of said cleaning fluid and is miscible therewith.

4. An assembly as recited in claim 3 wherein said fluid supply comprises at least two dispenser structures and at least two fluid reservoirs each containing said cleaning fluid, each of said two dispenser structures operatively connected to a different one of said two fluid reservoirs.

5. An assembly as recited in claim 4 wherein said cleaning fluid further comprises an alcohol-based solution.

6. An assembly as recited in claim 4 wherein one of said fluid reservoirs comprises a supply of said cleaning fluid and the other of said fluid reservoirs contains said at least one disinfectant agent.

7. An assembly as recited in claim 1 further comprising an activating assembly comprising a plurality of activating members disposed within said housing, each of said activating members forcibly disposed in activating relation to said dispenser structure during passage of the head portion along said path of travel.

8. An assembly as recited in claim 1 wherein said composition of said at least one disinfectant agent is formulated to be destructively effective against spore forms of clostridium difficile.

9. An assembly as recited in claim 1 wherein said at least one disinfectant agent includes a related compound of guanidine having bactericidal, fungicidal, sporicidal, antimicrobial or anti-viral activity.

10. An assembly as recited in claim 9 wherein said at least one disinfectant agent includes polyhexamethylene guanidine hydrophosphate.

11. An assembly as recited in claim 9 wherein said at least one disinfectant agent includes polyhexamethylene guanidine hydrochloride.

12. An assembly as recited in claim 1 wherein said at least one disinfectant agent comprises a coating disposed on at least one surface area within said interior of said housing.

13. An assembly as recited in claim 12 wherein said at least one surface area comprises a part of said housing.

14. An assembly as recited in claim 12 wherein said at least one said surface area is formed on at least one component operatively connected within said housing.

15. An assembly as recited in claim 1 wherein said at least one disinfectant agent is integrated within a material from which said housing is at least partially formed.

16. An assembly as recited in claim 15 wherein said at least one disinfectant agent is included in a material from which at least one operative component within said housing is formed.

17. An assembly as recited in claim 1 wherein said at least one disinfectant agent comprises a metallic material at least partially disposed within said housing.

18. An assembly as recited in claim 17 wherein said metallic material comprises copper.

19. An assembly as recited in claim 1 wherein said at least one disinfectant agent is at least partially incorporated within said applicator.

20. An assembly as recited in claim 19 wherein said composition of said at least one disinfectant agent is destructively effective against at least spore forms of clostridium difficile.

21. An assembly as recited in claim 1 wherein said at least one disinfectant agent and said cleaning fluid are independent formulations and both are in solution form.

22. An assembly as recited in claim 1 wherein said at least one disinfectant agent comprises chlorine dioxide.

23. An assembly as recited in claim 1 wherein said at least one disinfectant agent comprises derivatives of chlorine dioxide.

24. An assembly as recited in claim 1 wherein said at least one disinfectant agent comprises paracetyl ion-based compounds.

25. An assembly as recited in claim 1 wherein said at least one disinfectant agent comprises bleach.

26. An assembly as recited in claim 1 wherein said at least one disinfectant agent comprises compounds containing hydrogen peroxide.
