MicroSprayer® Aerosolizer for Guinea Pig

Model Number:
IA-1B-GP

The MicroSprayer® Aerosolizer – Model IA-1B-GP is designed for fast, targeted intratracheal aerosol administration to guinea pig. The device can be used to administer a precisely quantifiable, highly-concentrated, air-free plume of liquid aerosol directly into the lungs or other locations. It may also be used for intranasal or in vitro applications. It can aerosolize a wide range of liquids or particle solutions/suspensions, including pharmaceutical and biologic formulations, contrast/imaging agents and toxicological materials. (It does not administer dry powders.)

For intrapulmonary applications, the tip of the device is gently inserted down the trachea of the anesthetized animal – near to, but not touching the carina (first bifurcation). The portion that is inserted into the trachea measures 3″. The Model IA-1B operates with either a 0.5 ml precision glass syringe or a 1 ml commercial polycarbonate syringe.

  • Quick, precise aerosol dosing directly to the lungs – with no waste
  • Purely mechanical, air-free technology
  • Uses no heat, propellant, ultrasound or compressed air. No air burden to subject.
  • Unique patented design is light weight, hand-held, easy to use
  • Rounded tip permits safe, gentle intratracheal insertion
  • Made of rigid stainless steel tubing and other chemically resistant components
  • Fully sterilizable, autoclavable and reusable
  • Delivers a far higher volume and concentration than is possible with nebulizer/inhalation systems
  • Produces a far broader, more uniform distribution than liquid bolus/droplet instillation methods
  • Materials: Based on rigid, 19-gauge, stainless steel tubing and other chemically resistant components
  • 120-degree bend: All standard devices are made with a 120-degree bend to make it easier to see around one’s hand when trying to view the epiglottis. (Straight custom devices can be ordered.)
  • Length of intratracheal portion: 3″ (7.6 cm)
  • Tip is rounded to avoid harm to delicate tissues during insertion.
  • Operates with: Commercial, gas-tight 0.5ml precision glass syringe or 1 ml disposable polycarbonate syringe. NOTE: Due to the pressure required, syringes larger than 1 ml cannot be used to operate the Model 1A-1B.
  • Dose range: Designed to administer one dose at a time. Maximum dose size: 0.5 ml (glass) or 1 ml (polycarbonate). Smallest dose may need to be tested by end user. For doses larger than maximum capacity of the syringe, one syringe may be detached and refilled multiple times, or multiple syringes may be preloaded, attached and used one by one.
  • Outer diameter: .042″ (1.1 mm) except at tip which is .048″ (1.2 mm)
  • Inner diameter: .032″ (.813mm) (NOTE: liquid passes through patented aerosol components at the very tip. The diameter of these passageways is approximately 140 microns in diameter.)
  • Re-usable/Sterilizable: Can be cleaned and sterilized with very hot (filtered or distilled) water, organic solvents, by autoclave or ultrasound.

When analyzed with water, using the ml (1cc) polycarbonate syringe provided, the MicroSprayer® Aerosolizer – Model IA-1B produced a particle size distribution with a Mass Median Diameter (MMD) of 25-30 µm – when analyzed by laser defraction. NOTE: Results may vary, depending upon method of particle size analysis used, the material delivered and the length of the MicroSprayer® Aerosolizer

For intratracheal applications, the MicroSprayer® Aerosolizer is typically inserted directly into the trachea. The intratracheal portion of the Model IA-1B-GP is designed to reach from the front incisors to the carina in a standard size guinea pig. NOTE: Users may also pre-intubate the animal and insert the device down the trachea to the carina via an endotracheal tube. Doing so requires that the user calculate the measurements carefully so that:

  1. the tip of the MicroSprayer® Aerosolizer is long enough to emerge slightly from the end of the endotracheal tube when it is in position, and
  2. neither the tip of ET tube nor the tip of MicroSprayer® Aerosolizer should make contact with the carina when the plunger of the syringe is pushed

Intratracheal use of Penn-Century devices
For best results, position the tip
of the device near to – but not
touching the carina, or first
bifurcation.

Intratracheal use of Penn-Century devices

The process of intratracheal administration is essentially a form of intubation. For intrapulmonary applications, the tip of the MicroSprayer® Aerosolizer is gently inserted down the trachea of the anesthetized animal – near to, but not touching the carina (first bifurcation). The device operates with either a 0.5ml glass syringe or a 1 ml polycarbonate syringe.
