Abstract

The present disclosure is generally related to devices, methods and systems for cleaning, disinfecting and/or sterilizing a medical device, medical hoses and tubes and accessories thereof with ozone gas, in particular the disclosure relates to devices, methods and systems with multiple receptacles for providing closed-loop fluid pathways to distribute ozone gas to inner passageways and the outer compartments of medical devices. The devices in accordance with an embodiment of the disclosure have two or more receptacles for distributing ozone gas, a gas-tight compartment, an ozone operating system, and one or more connector units configured to fluidly migrate ozone in closed-loop treatment systems.

Claims

1. An ozone treatment system comprising:

an ozone operating system;

a first receptacle fluidly coupled to the ozone operating system, the first receptacle configured to receive ozone gas from the ozone operating system and to fluidly couple to a proximal end of an ozone conveyance line, said ozone conveyance line further comprising a distal end; and

a gas tight compartment comprising;

a lid and base comprising a plurality of walls, wherein said lid is movable between an open and a closed position, said lid and said plurality of walls define a cavity when said lid is in a closed position; and

a second receptacle configured to receive and engage with an intermediate portion of said ozone conveyance line so as to form a gas tight seal with the distal end of said ozone conveyance line disposed within said cavity, wherein said intermediate portion is between said proximal end and said distal end of said ozone conveyance line;

wherein;

said second receptacle is at least partially defined by at least one of said plurality of walls and said lid; and

said ozone operating system is configured to generate ozone gas for conveyance to said cavity of said gas tight compartment by said ozone conveyance line.

2. The ozone treatment system of claim 1, wherein said second receptacle is at least partially defined by said lid and one of said plurality of walls.

3. The ozone treatment system of claim 1, wherein:

said lid is coupled to said base and is movable between an open and said closed position;

at least one of said plurality of walls comprises both a lid sealing surface and a conveyance line sealing surface; and

said second receptacle is defined at least in part by said conveyance line sealing surface.

4. The ozone treatment system of claim 3, wherein when said lid is in said closed position:

a first portion of said lid engages said lid sealing surface; and

a second portion of said lid defines at least a portion of said second receptacle.

5. The ozone treatment system of claim 4, wherein said second portion of said lid and said lid sealing surface form said gas tight seal with said intermediate portion of said ozone conveyance line.

6. The ozone treatment system of claim 3, wherein:

said lid further comprises a sealing element; and

when said lid is in said closed position;

a first portion of said lid engages said lid sealing surface; and

said sealing element engages at least a portion of said intermediate portion of said ozone conveyance line, such that said second receptacle is at least partially defined by said conveyance line sealing surface and said sealing element.

7. The ozone treatment system of claim 6, wherein said sealing element extends from a downward facing side of said lid when said lid is in said closed position.

8. The ozone treatment system of claim 1, wherein:

said second receptacle defines a passageway into the cavity of said gas tight compartment;

the distal end of said ozone conveyance line is larger than said passageway.

9. The ozone treatment system of claim 1, wherein said ozone conveyance line is a hose of a medical instrument.

10. The ozone treatment system of claim 9, wherein said hose is a hose of a continuous positive airway pressure device.

11. The ozone treatment system of claim 10, further comprising an oxidizing catalyst downstream of said exhaust port, wherein said oxidizing catalyst is configured to break down ozone gas exhausted by said exhaust port.

12. The ozone treatment system of claim 11, wherein said oxidizing catalyst comprises magnesium oxide.

13. The ozone treatment system of claim 9, further comprising a mask coupled to the distal end of said hose.

14. The ozone treatment system of claim 1, further comprising an exhaust port fluidly coupled to said gas tight compartment, wherein the exhaust port is to exhaust ozone gas from said cavity.

15. The ozone treatment system of claim 1, further comprising an ozone sensor within said cavity.

16. The ozone treatment system of claim 1, wherein gas tight compartment is integral with said ozone operating system.

17. The ozone treatment system of claim 1, wherein said ozone operating system and said gas tight compartment are coupled to said base such that a position of the ozone operating system is fixed relative to a position of the gas tight compartment.

18. The ozone treatment system of claim 1, further comprising an air pump fluidly coupled to the ozone operating system.

19. An ozone treatment system comprising:

an ozone operating system configured to fluidly couple to a proximal end of a hose of a medical device, said hose further comprising a distal end; and

a gas tight compartment defined at least in part by a base comprising a plurality of walls and a lid, wherein;

said lid is movable between an open and a closed position; and

said plurality of walls comprises a first wall;

wherein said first wall and said lid are configured to define a receptacle configured to receive and form a gas tight seal with an intermediate portion of said hose, said intermediate portion being between said proximate and distal ends; and

said ozone operating system is configured to generate ozone gas for conveyance to said gas tight compartment by said hose.

20. The ozone treatment system of claim 19, wherein:

said first wall comprises an upward facing surface and a first portion of said receptacle;

said lid defines a second portion of said receptacle; and

when said lid is in said closed position and said intermediate portion is disposed within said receptacle;

a first portion of said lid engages said upward facing surface;

the first and second portions of said receptacle engage said intermediate portion of said hose to form said gas tight seal.

21. The ozone treatment system of claim 20, wherein when said intermediate portion of said hose is disposed within said receptacle, at least part of said intermediate portion is below said second portion of said receptacle.
