Description

The IA-1C MicroSprayer® by Penn-Century, Inc. delivers a plume of liquid aerosol (MMD of 16-22 µm) directly into the lungs. The device consists of a thin, flexible, stainless steel tube measuring only .64 millimeters in diameter (23-gauge) attached to a light, hand-operated, high-pressure syringe (see Accessory Model FMJ-250). Aerosol is generated by a unique, patented atomizer at the very tip of the tube. Available in any length, the Model IA-1C MicroSprayer® is thin enough to pass easily through the working channel of a bronchoscope or to be positioned in an endotracheal tube.

The IA-1C can be inserted deep into the trachea or even in selected secondary airways of appropriate sublects. The close proximity of the sprayer tip to critical pulmonary target sites produces a much deeper and more uniform distribution than is possible with instillation of a liquid bolus or drip. The MicroSprayer® is completely hydraulic, and manually operated. It requires no heat, ultrasound, electricity, compressed air, chemical propellant or other energy source.

Dimensional Information

Key: Length "A": Functional length, from bend to tip
Angle "B": Angle of bend
Length "C": Length from hub to bend

Note:
Optimal pulmonary distributions are obtained when the MicroSprayer® tip is located close to, but not touching the carina (first bifurcation).


*per ora insertion, without endotracheal tube


Custom Sizes

Model IA-1C MicroSprayers® can be made in any length or geometry (straight, various angle "B" dimensions). Include desired dimensions with your purchase order, or contact us for more information.

If an endotracheal tube is used, the length "A" should be increased accordingly, so that the tip of the delivery tube is located close to, but not touching, the carina (first bifurcation).
