Abstract
Breathing tube assemblies for use with a respiratory therapy device, such as a continuous positive airway pressure (CPAP) device, includes an elbow that permits adjustment of a position of the breathing tube assembly relative to the respiratory therapy device. In some arrangements, the breathing tube assembly includes a breathing tube and a swivel elbow. The breathing tube is rotationally fixed relative to the respiratory therapy device and the swivel elbow rotatable relative to the breathing tube. In other arrangements, the breathing tube assembly includes an elbow that can be coupled to the respiratory therapy device in one of several possible positions.
Claims32
A breathing tube assembly comprising:
- a breathing tube comprising:
- a first end,
- a second end,
- an interior passage, and
- an integrated electrical circuit,
- a gases connector comprising a first end and a second end, the second end of the gases connector being non-rotatably coupled to the first end of the breathing tube and comprising:
- a flange having an arcuate portion and an extension portion that extends outwardly from the arcuate portion,
- a shaft extending from the flange and defining a connector internal passage that communicates with the interior passage of the breathing tube, and
- an electrical terminal extending from the extension portion of the flange, wherein the electrical terminal comprises a plug arranged to connect with a port of a respiratory therapy device and the plug is spaced apart from the shaft, the electrical terminal comprises two electrical contacts that are exposed along a side surface of the plug, the two electrical contacts extending parallel to each other in a direction parallel to the shaft, the side surface being an outwardly-facing surface that faces away from the shaft,
- wherein the electrical terminal is connected to the integrated electrical circuit, and
- wherein the gases connector is arranged to be non-rotatably connected to an outlet of the respiratory therapy device;
- wherein the shaft includes a protrusion on an outer surface of the shaft, wherein the protrusion is a shaped projection extending from an outer surface of the shaft and spaced from the first end of the shaft, wherein the protrusion defines an interference or interlocking surface.
