Definitions

  • the invention relates to an inhalator and more particularly to an inhalator for treatment of the respiratory ducts of a patient with heated and medicated air.
  • Another object is the provision of such an inhalator which utilizes to the fullest possible extent the thermal energy supplied by the heater.
  • Yet another object is the provision of an inhalator in which exhaled gas is substantially completely vented to the atmosphere and replaced by yfresh gas substantially without mixing.
  • FIG. 1 shows a side elevation, pantly in axial section, of a preferred embodiment of the inhalator of the invention
  • FIG. 4 is a side elevation, largely in axial section, of a modified embodiment of ythe invention, with a portion broken away;
  • FIG. l there is shown a -face mask of resilient material shaped to t a human face in a substantially gas-tight manner.
  • the face mask 10 is releasably fastened to a connecting member 11 which connects the face mask to a handle portion 14 of an inhalator containing a heating element 12 arranged in a heating chamber 19.
  • the heating chamber is enclosed by a cylindrical ⁇ container 17 communicating at one end by an axial opening with the connecting member 11.
  • Heating chamber 19 com-municates Iby radial openings 18 in the cylindrical wall of container 17 adjacent the end thereof remote from the aforementioned axial opening with an annular insulating space 13 which extends substantially over the entire length of container 17 and is bounded radially outward therefrom atet by a wall 15 of cylindrical shape which constitutes the outer wall of the handle portion of the inhalator.
  • insulating space 13 communicates with the atmosphere by means of radial openings 16 in outer wall 15 which are longitudinally spaced from openings 18 in container 17 and serve as air inlets, the air flowing downward through insulating space 13, as shown in FIG. l, passing through openings 18 in to the heating chamber 19 and flowing upward therein past the heating element 12 countercurrent to the iiow of gas in space 13 to leave the heating chamber through the axial opening in the top thereof, thereby heating container 17 from the inside.
  • the air flowing downward in insulating space 13 prevents any heat from being transmitted from the outer surface of container 17 to the outer wall 15 of handle portion 14.
  • a bottom member 46 of heat-insulating material seals insulating space 13 and heating chamber 19 from the atmosphere. Openings 18 in the wall of container I17 are spaced a small distance lfrom bottom member 46 so that a radially inward flow of relatively cool air is maintained above the surface of insulating 'bottom member 46 and the outer surface of bottom member 46 remains cool during operation of the inhalator. Since the temperature diiferential between the inner and outer surfaces of bottom member 46 is small, heat losses through the bottom are negligible. Any heat transmitted from the heating chamber 19 through the cylindrical wall of container 17 is practically in its entirety utilized to preheat the air entering the inhalator through inlet opening 16 and flowing through insulating space 13.
  • the scope of this invention also is not limited to an inhalator employing a face mask, but any other outlet means communicating with the heating chamber of the inventive ⁇ device may be utilized for conveying a gas heated in said chamber to the respiratory ducts which are intended to be treated.
  • An inhalator for treatment of the respiratory ducts of a patient comprising in combination: a heating charnber, heater means in said chamber for heating a gas passing through said chamber, said heater means being in the form of a tubular body; thermostat means in said heating chamber and operatively connected to said heating means for automatically regulating the latter to maintain a preselected temperature in said heating chamber; a hollow member substantially enveloping said chamber and having a wall spaced from the outside of said chamber and dening therewith an insulating space; inlet means on said hollow member for connecting said space to a source of gas; conduit means spaced from said inlet means for connecting said insulating space to said chamber; a hollow connecting member connectable to an outlet means and communicating with said chamber at a portion thereof coaxial with said tubular heating means; irst check valve means interposed between said connecting member and said chamber to permit ow of gas substantially only in the direction from said chamber to said connecting member; a medication carrier adapted to hold volatile medication and releasably arranged in said connecting
