Ventilator circuit, adapter for use in ventilator circuit and methods for the use thereof

A ventilator circuit comprising:

• an oxygen supply;
• a user interface;
• and
• an adapter comprising:
• an inlet port defining a flow path and in flow communication with said oxygen supply;
• an outlet port in flow communication with said user interface, wherein said outlet port is in flow communication with said inlet port by way of a passageway;
• a medicament delivery port opening into said passageway;
• a valve moveable between a closed position wherein said valve closes said medicament delivery port and an open position wherein said medicament delivery port is open;
• a medicament delivery device communicating with said medicament delivery port and comprising a mouthpiece;
• and
• an actuator coupled to and positioned upstream of said valve, wherein said actuator comprises an end portion defining a central channel, wherein said end portion is disposed in said mouthpiece of said medicament delivery device.

A method of delivering a medicament comprising:

• introducing a gas to an inlet port of an adapter along a flow path;
• passing said gas through a passageway defined by said adapter;
• opening a valve by inserting a mouthpiece of a pressurized metered dose inhaler into a medicament delivery port opening, engaging an actuator connected to said valve with said mouthpiece, and disposing an end portion of said actuator into an interior of said mouthpiece, wherein said end portion comprises a central channel;
• actuating said pressurized metered dose inhaler and releasing a medicament through said central channel and into said medicament delivery port opening;
• introducing said medicament from said medicament delivery port opening into said passageway and thereby entraining said medicament with said gas;
• and
• delivering said medicament to a user through an outlet port of said adapter communicating with said interior passageway.
