Abstract

An adapter for selectively providing fluid to a device from one of multiple fluid sources has a body with a first inlet for connecting a first one of the multiple fluid sources to the device and a second inlet for connecting a second one of the multiple fluid sources to the device. The adapter also includes a handle that is movably coupled to the body and includes an access control element. The handle is configured to secure the body to a device when the adapter is in either of a first position or a second position that is rotated relative to the first configuration. The access control element obstructs access to the second inlet when the adapter is secured to the device in the first position and the access control element obstructs access to the first inlet when the adapter is secured to the device in the second position.

First claim

What is claimed is:

1. An adapter for selectively providing fluid to a device from one of multiple fluid sources, the adapter comprising:
a body;
a first inlet for connecting a first one of the multiple fluid sources to the device and a second inlet for connecting a second one of the multiple fluid sources to the device, each of the first and second inlets coupled to the body; and
a handle that is movably coupled to the body and comprises an access control element and a shaft, the shaft integrally formed with the handle, the shaft being rotationally coupled to the body and the shaft being configured for detachably coupling the body to the device to secure the body to the device when the adapter is in either of a first position or a second position that is rotated 180° relative to the first position, wherein when the adapter is secured to the device in the first position a first empty space is between the access control element and the second inlet and the access control element is adjacent to the second inlet to obstruct access to the second inlet and when the adapter is secured to the device in the second position a second empty space is between the access control element and the first inlet and the access control element is adjacent to the first inlet to obstruct access to the first inlet.

2. The adapter of claim 1 , wherein the first inlet is configured to mate with a first connector that is connected to the first one of the multiple fluid sources and the second inlet is configured to mate with a second connector that is connected to the second one of the multiple fluid sources.

3. The adapter of claim 2 , wherein the second connector is a different type of connector from the first connector.

4. The adapter of claim 2 , wherein:
the first connector is associated with a first gas mixture; and
the second connector is associated with a second gas mixture that is different from the first gas mixture.

5. The adapter of claim 1 , wherein:
the body comprises a center plane; and
the first and second inlets are symmetrically located on opposite sides of the center plane.

6. The adapter of claim 5 , further comprising first and second coupling ports that are symmetrically located on opposite sides of the center plane on a back side of the body, the first and second coupling ports being in respective fluid communication with the first and second inlets.

7. The adapter of claim 6 , wherein the first and second coupling ports are identical and located such that the first coupling port is partially disposed within a fluid passage of the device when the adapter is secured to the device in the first position and the second coupling port is partially disposed within the fluid passage of the device when the adapter is secured to the device in the second position.

8. The adapter of claim 7 , wherein the first and second coupling ports are each configured to detachably and sealingly mate with the fluid passage of the device.

9. The adapter of claim 1 , wherein the handle further comprises a latching pin configured to engage a securing feature of the device so as to secure the adapter to the device in either of the first and second positions.

10. The adapter of claim 1 , wherein the access control element comprises a paddle that is disposed proximate to the second inlet when the adapter is secured to the device in the first position and disposed proximate to the first inlet when the adapter is secured to the device in the second position.

11. The adapter of claim 1 , further comprising a machine-detectable indicator that is disposed in a first location relative to the device when the adapter is secured to the device in the first position and disposed in a second location that is different from the first location when the adapter is secured to the device in the second position.

12. A ventilator comprising:
a housing comprising a fluid passage; and
an adapter comprising:
a body;
a first inlet and a second inlet each coupled to the body; and
a handle that is movably coupled to the body and comprising an access control element and a shaft, the shaft integrally formed with the handle, the shaft being rotationally coupled to the body and the shaft being configured for detachably coupling the body to the housing to secure the body to the housing in either of a first position or a second position that is rotated 180° relative to the first position, wherein when the adapter is secured to the housing in the first position a first empty space is between the access control element and the second inlet and the access control element is adjacent to the second inlet to obstruct access to the second inlet and when the adapter is secured to the housing in the second position a second empty space is between the access control element and the first inlet and the access control element is adjacent to the first inlet to obstruct access to the first inlet.

13. The ventilator of claim 12 , wherein the first inlet is configured to mate with a first connector and the second inlet is configured to mate with a second connector.

14. The ventilator of claim 13 , wherein the second connector is a different connector type from the first connector.

15. The ventilator of claim 13 , wherein:
the first connector is associated with a first gas mixture; and
the second connector is associated with a second gas mixture that is different from the first gas mixture.

16. The ventilator of claim 12 , wherein:
the body comprises a center plane; and
the first and second inlets are symmetrically located on opposite sides of the center plane.

17. The ventilator of claim 16 , wherein:
the housing further comprises a docking location configured to accept the adapter in either of the first or second positions, the docking location comprising a fluid passage;
the adapter further comprises a first coupling port and a second coupling port that are symmetrically located on opposite sides of the center plane on a back side of the body such that the first coupling port is partially disposed within the fluid passage when the adapter is secured to the docking location in the first position and the second coupling port is partially disposed within the fluid passage when the adapter is secured to the docking location in the second position, the first and second coupling ports being in respective fluid communication with the first and second inlets.

18. The ventilator of claim 17 , wherein the first and second coupling ports are each configured to detachably and sealingly mate with the fluid passage of the housing.

19. The ventilator of claim 17 , wherein:
the housing further comprises a securing feature; and
the handle further comprises a latching pin configured to engage the securing feature of the housing when the adapter is secured to the docking location in either of the first and second positions and the handle is in a latched position,
wherein the latching pin is disengaged from the securing feature when the handle is in an unlatched position.
