Filed:

Appl. No.:

13/155915

William A. Hagen - Canton GA, US

International Classification:

A61M 16/10

US Classification:

12820312

Abstract:

There is provided a metered dose inhaler port for a ventilated patient where the port has a critical distance (as defined herein) sufficient to allow a metered dose inhaler to discharge into the port when the metered dose inhaler has a dose counter attached to it. The port must also have a stiffness sufficient to avoid bending upon insertion of the metered dose inhaler stem. The disclosure discusses an elongation of the metered dose inhaler actuator port to allow for use with metered dose inhaler canisters with and without dose counters. This solution maintains the original drug path length and so minimizes changes that might change the drug dispersal characteristics of the port and require governmental approval or re-education of medical personnel.

Abstract:

A respiratory access assembly may include a manifold having a first mating surface defining a first port opening. The respiratory access assembly may include a rotatable adapter having a second mating surface defining a second port opening and a seal assembly disposed between the manifold and the rotatable adapter that includes a first seal ring, a second seal ring, and an outer seal ring disposed proximate an outer perimeter of at least one of the manifold or the rotatable adapter. The rotatable adapter may be rotatable relative to the manifold between an open configuration and a closed configuration. The seal assembly may include a connection portion connected between the first seal ring and the second seal ring. The connection portion may form a seal between the first mating surface and the second mating surface between the first seal ring and the second seal ring.
