Abstract

A medication delivery apparatus and system for the application of a medical agent to a treatment site, such as an airway, and method for use of same are disclosed. In one embodiment of the medication delivery apparatus and system, a reservoir supplies a medical agent to a lower chamber of a housing wherein an ultrasonic transducer applies ultrasonic energy thereto, thereby nebulizing the medical agent. A control valve is interposed between a source of positive pressure air and an upper chamber of the housing to selectively apply positive air pressure to the upper chamber. Upon the application of positive air pressure, the airflow delivers the nebulized medical agent to a target location, such as the airway.

Dependent claims

A delivery apparatus for the application of a medical agent to a treatment site, the medication delivery apparatus comprising:

a housing, the housing being sized so as to be securable to a hand-held medical device;
a reservoir configured to contain the medical agent, the reservoir disposed in fluid communication with a supply channel and a circulation channel;
a nebulization housing including a lower chamber and an upper chamber;
the lower chamber being disposed in fluid communication with the supply channel and the circulation channel;
an upper channel being disposed in fluid communication with an airflow channel and a delivery channel;
an ultrasonic transducer positioned in the lower chamber, the ultrasonic transducer configured to generate, upon energization, ultrasonic energy;
a control valve interposed between a source of positive pressure air and the airflow channel, the control valve configured to selectively apply air to the airflow channel;
the reservoir, the supply channel, the circulation channel, the nebulization housing, the airflow channel, the delivery channel, and the control valve being located in the housing;
the control valve being controllable by a controller, the controller being externally positioned on the housing;
a first operational state of the control valve, wherein the control valve is open, wherein the medical agent is configured to circulate from the reservoir to the lower chamber, wherein the ultrasonic transducer is configured to apply ultrasonic energy to the medical agent, thereby producing a nebulized medical agent adapted to be carried by the application of air to the delivery channel;
and
a second operational state of the control valve, wherein the control valve is closed, wherein the medical agent is configured to circulate from the reservoir to the lower chamber, wherein the ultrasonic transducer is configured to apply ultrasonic energy to the medical agent, thereby producing a nebulized medical agent adapted to remain in the upper chamber.
