Abstract
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 remain…
