This invention is a device () for inspiration of a mist from a nebulizer, having an inlet connector () adapted to engage an outlet port of a nebulizer, a hollow mouthpiece element () for insertion into a patient's mouth; a conduit () forming a fluid connection between the inlet connector, and the hollow mouthpiece element. An exhaust valve () is provided for removing expiratory gases which are exhaled into the mouthpiece element to the ambient atmosphere via an exhaust/positive expiratory pressure (PEP) valve (). The PEP valve is positioned on the conduit between the inlet connector, and the mouthpiece element; and a filter housing () containing a filter () for filtering the exhaled gases passing from the exhaust/PEP valve.

Nebulizer mouthpiece and accessories

This invention is a device ( ) for inspiration of a mist from a nebulizer, the device comprising an inlet connector ( ) adapted to engage an outlet port of a nebulizer; a hollow mouthpiece element ( ) for insertion into a patient's mouth; a conduit ( ) forming a fluid connection between the inlet connector, and the hollow mouthpiece element; an exhaust valve ( ) for removing expiratory gases which are exhaled into the mouthpiece element to the ambient atmosphere via the exhaust/positive expiratory pressure (PEP) valve ( ) positioned on the conduit between the inlet connector, and the mouthpiece element; and a filter housing ( ) containing a filter ( ) for filtering the exhaled gases passing from the exhaust/PEP valve.

A mouth piece exhalation valve for a nebulizer or breathing circuit. The nebulizer has an internal passageway containing an offset causing an inspiration mist flow to bypass the exhaust valve without impingement. The offset includes a deflector which aids in the deflection of the inspiration mist flow away from the exhaust valve. The deflector is also utilized for directing the exhaust flow upon expiration by a patient through the exhaust valve. The exhaust valve design includes a flap or disc having leaves formed by peripheral arcuate cuts to facilitate the opening and the closing of the leafs in accordance with the expiration and inhalation of a patient respectively. The cuts also aid in the re-introduction of any accumulation of fluid on the external surface of the disc and valve back into the inspirational cycle so as to minimize any external buildup of fluid.

Mouthpiece for a nebulizer

A tubing end-piece interconnects a free end of a piece of tubing and a tubing connector or fitting so that a fluid can flow between the tubing and the fitting or connector. The tubing end-piece includes a body member extending along a longitudinal axis with a bore extending longitudinally therethrough. The body member has an elongated body portion, a doughnut-shaped head portion and a frustoconically-shaped tail portion. The body portion has an outer body surface configured in a shape of a frustum that tapers from a first end and towards a second end. The doughnut-shaped head portion is connected to the first end of said body portion and extends radially outwardly relative to the longitudinal axis to form in cross-section an outer curved surface commencing from the first end and terminating in an outer peripheral edge which defines a first opening into the bore. A frustoconically-shaped tail portion is connected to the second end of the body portion and tapers from the second end and towards a second opening into the bore. The body member has an inner first surface and an inner second surface defining the bore and has a plurality of splines which are spaced apart from one another and extend longitudinally along and outwardly from the outer body surface. The present invention also includes a connector adapted to interconnect a pair of tubing end-pieces so that the fluid can flow between and through the respective pieces of tubing and the pair of tubing connectors, and present a connection which resists snagging when trailed from a portable or fixed source of oxygen gas to an ambulatory patient.
