Abstract

A horizontally elongated, shallow, hollow nebulizer body has vertically spaced horizontal top and bottom walls. The bottom wall is of much shorter length. The horizontal bottom wall is of relatively short length and terminating at the side opposite of a vertical side wall, in an upwardly oblique bottom wall portion extending to the end of the horizontal top wall remote from said vertical end wall. The nebulizer chamber produced thereby drains in the direction of the short length horizontal bottom wall of the hollow body. A horizontal source gas supply tube extends through the vertical end wall of the nebulizer body, and connects to a vertically upright pipe terminating in a reduced diameter nozzle opening. An inverted cup-like hollow cylindrical nozzle member is mounted concentrically about the vertical pipe, has an internal diameter in excess of the outside diameter of the short vertical pipe to form a liquid aspirating passage leading to a mixing chamber at the upper end of the short vertical pipe. A medication injection port is formed by a short length horizontal pipe integral with the nebulizer body end wall. A valved T tube assembly is fixedly mounted to the top wall of the nebulizer to the side of that body remote from the inverted cup-shaped nozzle member and is open to the nebulizer chamber to receive selectively, depending upon valve setting, the source gas and a liquid medication in fine mist particle form for selective feed to the interior airways of a patient via an otherwise conventional ventilator circuit.
