Aerosol delivery apparatus-ventilator connector with adapter (VCA) and medicament dispenser and adapter (MDA)

A VCA

• which is “L” shaped
• which should be used in the circuit only as inverse L—“┌”.
• with a provision for an adapter on the horizontal limb of the “┌”.
• with an adapter on the horizontal limb such that its lumen is in straight line with the lumen of the vertical limb of “┌”.
• with an adapter whose framework perfectly fits the framework of MDA

An MDA

• with provision for aerosol delivery of medications to the lungs via a metered dose inhaler (MDI)
• with an adapter designed to fit the nozzle of MDI cannister.
• with cylindrical shape such that fits into the cylindrical framework of the VCA adapter.
• which tapers at its distal tip to reach an inner diameter (ID) of an pinhole that marks the origin of a semi-rigid cannula.
• with a semi-rigid cannula that could be manipulated distally through the lumen of the ET tube
• with a cannula without fling when the pressure valve of MDI is actuated
• with a cannula whose ID is small enough for the particles generated by a MDI at the proximal end to be delivered at the distal tip of the ET tube in aerosol form
• with a proximal cylindrical part whose circumference is greater than the outer circumference of the VCA adapter to prevent MDA from slipping into the inspiratory circuit
• with an additional safety feature in the form of a circular plate wrapped around the MDA to prevent it from slipping into the vertical limb of VCA.
