Abstract

A system for decontaminating an enclosed area includes a reservoir containing a disinfectant solution therein. One or more pumps are in fluid communication with the reservoir. One or more ports are operatively connected to the reservoir or operatively connected to an enclosed area to be decontaminated or operatively connected to the reservoir and to an enclosed area to be decontaminated. One or more connector assemblies are removably attachable to the one or more ports to provide fluid flow communication between the disinfectant solution source and the enclosure to be decontaminated.

Claims

1. A system for decontaminating an enclosed area, comprising:

a reservoir containing a disinfectant solution therein;

one or more pumps in fluid communication with the reservoir;

a pressurized air source;

one or more ports, each port comprising a first coupler and a second coupler, wherein the first coupler is operatively connected to the reservoir and the second coupler is operatively connected to the pressurized air source, or wherein the first coupler is operatively connected to an enclosed area to be decontaminated and the second coupler is operatively connected to the enclosed area to be decontaminated; and

,

one or more connector assemblies removably attachable to the one or more ports, each connector assembly comprising a first fluid line in fluid communication with the first coupler to provide fluid flow communication between the reservoir and the enclosed area to be decontaminated, and a second fluid line in fluid communication with the second coupler to provide fluid flow communication between the pressurized air source and the enclosed area to be decontaminated.

2. The system of claim 1, further comprising one or more nozzles mounted to an internal surface of the enclosed area to be decontaminated, each nozzle in fluid flow communication with;

a port or a respective port of the one or more ports, a connector assembly or a respective connector assembly of the one or more connector assemblies, the pressurized air source, and the reservoir when the connector assembly or the respective connector assembly is connected to the port or the respective port, wherein the one or more nozzles comprise atomizing nozzles.

3. The system of claim 2, wherein each connector assembly of the one or more connector assemblies comprises an umbilical housing in which a respective first fluid line and a respective second fluid line are housed, and a respective connector head attached to a respective end of the umbilical housing and configured to cooperate with the one or more ports to provide fluid flow communication between the reservoir and a respective nozzle.

4. The system of claim 2, further comprising a nozzle assembly mounted to the internal surface of the enclosed area to be decontaminated and comprising the one or more nozzles, the nozzle assembly further comprising an electrical component, the one or more ports each comprising an electrical connector, each connector assembly of the one or more connector assemblies further comprising an electrical line configured to deliver electrical power to the electrical component and an electrical lead at an end of the electrical line configured to cooperate with the electrical connector.

5. The system of claim 4, wherein the electrical component comprises at least one of:

a motion detector configured to detect motion in the enclosed area to be decontaminated; and

a warning light.

6. The system of claim 2, further comprising:

a vacuum pump in fluid communication with the one or more ports;

a sensor in fluid communication with the vacuum pump and configured to detect a level of disinfectant;

a nozzle assembly mounted to the internal surface of the enclosed area to be decontaminated and comprising the one or more nozzles, the nozzle assembly further comprising a sensor tube opening;

wherein the nozzle assembly further comprises a third fluid line that provides fluid communication between the sensor tube opening and the sensor.

7. The system of claim 1, wherein the reservoir is a component of a mobile decontamination unit.

8. The system of claim 7, further comprising:

one or more atomizing nozzles mounted to an internal surface that defines an interior space of a vehicle;

wherein at least one port of the one or more ports is mounted to an exterior wall of the vehicle, wherein a respective first coupler of the at least one port is in fluid communication with a respective nozzle of the one or more atomizing nozzles, and wherein a respective second coupler of the at least one port is in fluid communication with the respective nozzle.

9. The system of claim 8, wherein the mobile decontamination unit comprises a cart with wheels and the reservoir is on the cart.

10. The system of claim 1, wherein the reservoir is a component of a stationary unit.

11. The system of claim 10, wherein the stationary unit comprises a housing mounted to a wall and the reservoir is in the housing and the one or more pumps are in the housing.

12. The system of claim 1, wherein the pressurized air source comprises an air compressor.

13. A system for decontaminating an enclosed area, comprising:

a decontamination unit including a reservoir containing a disinfectant solution;

a supply of pressurized air;

an atomizing nozzle mounted within the enclosed area to be decontaminated;

one or more ports that are in fluid communication with the reservoir and the supply of pressurized air, and/or the atomizing nozzle, wherein the one or more ports comprises at least two fluid inlet portals or at least two fluid outlet portals;

one or more connector assemblies operatively connectable to the reservoir and the supply of pressurized air and/or the one or more ports;

wherein the one or more connector assemblies comprises an umbilical housing having a first fluid line through which the disinfectant solution flows from the reservoir to the atomizing nozzle and a second fluid line through which pressurized air flows from the supply of pressurized air to the atomizing nozzle; and

,

the one or more connector assemblies further comprising a connector head at an end of the umbilical housing wherein the connector head is configured for removable coupling to the one or more ports and the at least two fluid inlet or outlet portals.

14. The system of claim 13, further comprising one or more pumps in fluid communication with the reservoir.

15. The system of claim 13, wherein in the one or more ports includes a port mounted to a wall defining at least a portion of the enclosed area.

16. The system of claim 15, wherein the port is mounted to a surface of the wall external to the enclosed area.

17. The system of claim 13, wherein the decontamination unit comprises a housing on a cart with wheels and the reservoir and the supply of pressurized air are within the housing.

18. The system of claim 13, wherein the decontamination unit comprises a housing mounted to a wall, and the reservoir and the supply of pressurized air are disposed within the housing.

19. The system of claim 13, wherein the decontamination unit comprises a spring-loaded reel on which an umbilical housing of a respective connector assembly is wound.

20. The system of claim 13, wherein the decontamination unit comprises a power source, and the one or more connector assemblies comprise electrical lines for electrical connection to an electrical component of the system.
