Description
The IA-1B MicroSprayer® by PennCentury, Inc. delivers a plume of aerosol (MMD of 25-30 µm) directly into the lungs. The device is based on a 19-gauge, stainless steel tube and is operated by a plastic syringe. Aerosol is generated by a unique, patented atomizer at the very tip of the tube, which measures only 1.5 millimeters in diameter. The Model IA-1B MicroSprayer® is available in any length or geometry.
The IA-1B can be inserted deep into the trachea. 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. The IA-1B 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-1B 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).
