A disposable adapter valve inserted into a T connector in a ventilator hose allows connecting and disconnecting a nebulizer to the hose without loss of positive and expiratory pressure (PEEP). An integral press-on cap covers the open end of the adapter valve when the nebulizer or a drain container is not connected, preventing leakage of fluids and preventing contamination of the inner surface of the adapter valve by airborne bacteria and the like.

An adapter/valve device for quick-connect coupling or decoupling of an accessory such as a nebulizer or a drain container to a three port coupler of a ventilator hose without interrupting positive pressure of gas in the ventilator hose or exposing the interior of the ventilator hose to outside contamination, the adapter valve comprising in combination: (a) a generally tubular housing with a tapered upper end adapted for insertion into a port of the three port coupler, the housing including i. a generally cylindrical lower cavity adapted to receive insertion of an open-ended tubular connector of the accessory, ii. a generally cylindrical upper cavity coaxial with the lower cavity, the lower cavity and upper cavity forming a passage through the housing, an upper end of the housing forming a planar, circular lip which is approximately flush with a wall of a passage of the ventilator hose extending through the three port coupler; (b) a stationary hub centered in the upper cavity adjacent to the lip and a plurality of spaced spokes attaching the stationary hub to a wall of the upper cavity; (c) a valve assembly including i. a planar circular disc forming a valve plate, ii. a rod perpendicular to the disc and passing through a hole in the stationary hub and having an upper end rigidly attached to the disc, iii. a compression spring disposed around the rod and having an upper end abutting the stationary hub, iv. a movable hub located in the lower cavity and rigidly attached to a lower end of the rod, a lower end of the spring abutting the movable hub, urging the disc against the lip to form a seal therewith, and a plurality of spaced abutment spokes each having an inner end rigidly attached to the movable hub and an outer end adjacent to and spaced from a wall of the lower cavity, the abutment spokes being adapted to abut a circular wall end of the tubular connector as it is inserted into the lower cavity and thereby raise the disc away from the lip, exposing an interior of the ventilator tube and the three port coupler to an interior of the accessory, the valve assembly resealing the disc with the lip when the tubular connector is withdrawn from the first cavity.
