How to Fill Drive 646 Nebulizer?

• Remove port cap and position nebulizer aerosol port in an upward position.
• Fill nebulizer through the main aerosol port with a prescribed amount of medication.
• The nebulizer is designed with a no-spill internal rim to prevent the medication from accidentally spilling.
• Do not fill above o-ring at the base of medication reservoir. Overfilling may cause nebulizer to leak.

How to use Drive 646 Nebulizer?

• It is important to be in a comfortable upright position during the treatment.
• Fill nebulizer as previously instructed. Attach mouthpiece to T-piece.
• Note: The Model 646 nebulizer includes a mouthpiece specifically designed for use with this model. It is not compatible with other sizes of mouthpieces.
• Attach nebulizer tubing to a mechanical compressor such as the DeVilbiss 5650, 4650, or 3655 series compressors. If compressed air or oxygen is used, set regulator to permit 5-7 lbs. pressure or a flow of 6-8 liters per minute.
• To attain maximum aerosol output, remove air vent cap from side vent of the nebulizer.
• Turn on an air compressor. Aerosol will not flow until thumb-valve is closed as described below.
• Position mouthpiece between teeth. Place finger over thumb-valve. As aerosol begins to flow, inhale deeply. At the end of the inhalation, remove finger from thumb-valve and hold breath for two seconds.
• Remove nebulizer from mouth and exhale slowly.
• This procedure should be repeated until all prescribed medication is nebulized.
• Note: Blow through T-piece Model 646 nebulizer is designed to remain in the mouth during exhalation if desired.
• The nebulizer may be used without a mouthpiece.
• Position nebulizer aerosol port in mouth so that aerosol avoids teeth and tongue. Follow same administration procedure as described above.

How to clean Drive Model 646 Nebulizer?

• Remove nebulizer tubing from compressor and nebulizer. Remove mask or mouthpiece.
• Unscrew upper half of nebulizer from the lower half and rinse all parts under hot tap water after every use.
• Daily, wash nebulizer, jet, mouthpiece, thumb-valve in hot, soapy water. If jet is clogged, use cleaning wire (not shown).
• Rinse with hot tap water for 30 seconds, then soak in one part white vinegar (>=5% acetic acid concentration) to three parts hot water (131ºF-149ºF/55ºC - 65ºC) for 30 minutes. Rinse with hot tap water and air dry. Replace or clean tubing monthly by following nebulizer cleaning instructions.
• To remove excess water from tubing, attach to compressor or air source and allow air to pass through tubing until excess moisture is removed.
• A nebulizer is constructed of latex-free polycarbonate that, with the exception of the mouthpiece and o-ring, will withstand sterilization by autoclaving (@ 273ºF for 15 minutes) or boiling. It may also be sterilized with any suitable germicidal agent.
• Always prepare a fresh solution for each cleaning cycle.
• To avoid possible contamination, the nebulizer should be stored with port and vent caps in place until next treatment.
