Improved nebulizing apparatus is disclosed for generating a heated liquid-dispensed-in-gas mist for administration to a patient undergoing aerosol therapy. The apparatus includes a novel fastening means for attaching a heater unit to the underside of a reservoir containing the liquid. The heater unit is easily attached and detached and yet enables good heat conductivity for heating the liquid within the interior of the reservoir. The bottom of the reservoir itself includes a concave heat conducting surface which, in operation, is in direct contact with the surface of the heater unit. The fastening means includes at least two draw clips which extend upwardly from the heater unit and which engage the reservoir to effect the desired fastening. By an adjustment of the draw clips with respect to the heater unit, the heat conducting surface of the reservoir can be forced out of its concavity to a flat, planar shape in good surface contact with the heater to enhance heat conductivity to liquid within the reservoir. The draw clips are held within stopping lugs on the reservoir to prevent rotation of the reservoir and thus preventing separation of the heat conducting surface from the remaining reservoir and accidental spillage of the hot liquid within the reservoir.

Nebulizer apparatus for generating a heated liquid-in-gas mist for administration to a patient in the course of aerosol therapy; said apparatus comprising in combination: reservoir means for containing liquid to be dispersed in said gas; gas inlet means for providing an input of gas to said apparatus; means for mixing said liquid with said gas to form said mist; mist outlet means for providing said mist toward said patient; a normally downwardly concave thermally conductive heat transfer plate forming the bottom of said reservoir means; heating means underlying said reservoir means for heating said liquid, said heating means being separable from said reservoir and having a substantially flat surface; fastening means for positively retaining said heating means in operative association with said reservoir in heat transmissive relationship with said heat transfer plate, said fastening means comprising draw clips secured to and extending upwardly from said heating means and being engaged with said reservoir means, and adjusting means adapted to move said draw clips to draw said heat transfer plate tightly against said substantially flat surface of said heating means to cause said heat transfer plate to lose its downward concavity and assume a substantially flat configuration against said heating means to establish and maintain good thermal contact therebetween.
