Product Classification

• Device: holding chambers, direct patient interface
• Regulation Description: Nebulizer.
• Definition: Holding chambers are devices that are used with nebulizers and metered dose inhalers and are comprised of a reservoir into which an aerosol medication is dispensed. A holding chamber uses a valved mouthpiece through which the patient inhales the dispensed medication. Holding chambers are intended to minimize delivery of large aerosolized particles
• Physical State: Holding Chambers are frequently made of plastic, and can be tube shaped.
• Technical Method: By holding drugs after aerosolization, holding chambers are intended to minimize delivery of large aerosolized particles which would otherwise depisit in the mouth, throat, or upper airway
• Target Area: Holding Chambers contact the mouth. The drug they are holding is intended for the lower airways
