  • embodiments of the present invention generally provide a system for delivering therapeutically conditioned air in the vicinity of a patient's nose and mouth without attaching a delivery device to the patient.
  • an exemplary embodiment of an air delivery device 10 may comprise a tube 1 2, an inlet member 16, an outlet member 14 and one or more clamps 1 8.
  • the device 10 may be connected through a connection tube 20 to a source of therapeutically conditioned air such as a centralized hospital air source 22.
  • a source of therapeutically conditioned air such as a centralized hospital air source 22.
  • One of the clamps 1 8 may be attached to a horizontal portion of a bed rail 24.
  • Another one of the clamps 1 8 may be attached to a vertical portion of the bed rail 24.
  • the outlet 14 of the device 10 may be positioned next to, but not in contact with, a mouth and nose of a patient 30.
  • the device 1 0 may be provided with shape-retention elements so that the device 1 0 may be bent and positioned in any one of many different configurations to align with the position of the patient 30.
  • a shape-retention wire 32 may be placed inside the tube 12 and supported on wire-supporting clips 34.
  • the wire 32 may be soft stainless steel with a diameter between about 0.050 inch to about 0.1 0 inch.
  • a plurality of the clips 34 may be spaced at approximately equal intervals along the length of the interior of the tube 12.
  • the tube 1 2 may be bent into a desired configuration so that it may be attached to any supporting structure such as the bedrail 24.
  • an exemplary embodiment of the clamp 18 may be spring-biased and may include a tube gripping member 18-1 which may be shaped as a partially open cylindrical structure that may be snapped onto the tube 12 at a desired location on the tube 1 2.
  • a first handle member 18-2 may be integrally formed with the tube- gripping member 18-1 .
  • An arcuate connecting segment 18-3 may be interposed between the handle member 1 8-2 and the tube-gripping member 1 8- 1 .
  • the arcuate connecting segment 1 8-3 may have a concave curved shape that may correspond approximately to a shape of the bedrail 24.
  • a second handle member 1 8-4 may be affixed to the first handle member 18-2 with a torsion spring 1 8-5.
  • An arcuate rail-gripping member 18-6 may be integrally formed with the handle member 18-4.
  • the rail-gripping member 1 8-6 may be shaped into a concave curve that may correspond approximately to the shape of the bedrail 24.
  • the rail-gripping member 18-6 and the arcuate segment 18-3 may separate from one another so that the clamp may be placed over the bedrail 24.
  • the torsion spring 18-5 may act to bring the rail-gripping member 18-6 and the arcuate segment 18-3 into engagement with the bedrail 24 so that the tube 12 may be held in position against the bedrail 24.
  • the tube 1 2 may be corrugated hollow plastic air hose having an inside diameter of about 0.08 inch to about 0.10 inch.
  • the clips 34 may be adapted to interlock with corrugations 1 2-1 of the tube 12 so to maintain longitudinal or axial position of the clip 34 within the tube 12.
  • the clip 34 may have a generally cylindrical or open-ring shape.
  • the clip 34 may be formed from molded plastic and may be flexible.
  • the clip 34 may be compressed so that it may have a compressed outer diameter smaller than an internal diameter of the tube 1 2. When released from a compressed state, the clip 34 may spring back to a nominal size with its nominal outer diameter greater than the inner diameter of the tube 1 2.
  • An outer surface of the clip 34 may be provided with a retention ridge 36.
  • the ridge 36 may be shaped to correspond to an interior shape of any one of the corrugations 12-1 of the tube 12.
  • the clip 34 may be placed in the tube 12 in a compressed state and then allowed to expand to its nominal size. When the clip 34 is expanded within the tube 1 2, its longitudinal or axial position is maintained because of interlocking engagement of the ridge 36 and one of the corrugations 12-1 of the tube.
  • the clip 34 may have a unique configuration that may facilitate assembly of the shape-retention wire 32 into the tube 12.
  • the clip 34 may be provided with a hollow internal projection 38 with a hole 39 through which the shape-retention wire 32 may pass.
  • the hole 39 may have a diameter such that the wire 32 fits snugly in the hole 39.
  • Hollow lobes 40 may be provided and positioned in two different planes so that when the clip 34 is compressed, the lobes 40 may overlap one another (see Figure 6). When the lobes 40 are overlapped, holes 41 in the lobes 40 may be aligned so that an assembly wire 42 may be passed through both of the holes 41 .
  • the shape-retention wire 32 may be installed within the tube 12 by performing the following steps shown in a flowchart 700 of Figure 7.
  • a step 702 one of the clips 34 may be compressed so the holes 41 are aligned.
  • the assembly wire 42 may be threaded though both of the holes 41 of one of the clips 34.
  • a plurality of the clip 34 may be similarly threaded onto the assembly wire 42.
  • the shape-retention wire 32 may be pushed into the holes 39 of the clips 34 which are threaded on the assembly wire 42.
  • the clips 34 may be spaced away from one another along the wire 32 so that each of the clips 34 is approximately equidistant from its adjacent clip 34.
  • the equidistantly spaced clips 34, the shape-retention wire 32 and the assembly wire 42 may be inserted into the tube 1 2.
  • the assembly wire 42 may be pulled out of the holes 41 so that the clips 34 may expand and so that the ridges 36 may engage with the corrugations 12-1 .
  • the clips 34 may remain engaged with the tube 12 and the shape-retention wire 32 may be supported with the equidistantly spaced clips 34.
  • an exemplary standalone air delivery system 100 may be constructed and may be useful in a residential setting in which a patient may be in his or own bed at home.
  • the system 1 00 may comprise a nebulizer 102, a connection hose 104 and one of the air delivery devices 10.
  • the system 100 may include a medication dispensing device 1 06 which may be employed to inject medication into an air stream that may be conveyed to a patient though the air delivery device 1 0.
