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.
