It is intended for adult patients consistent with the indications for the aerosol medication The Disposable Nebulizer Set is for single use for less than 24 hours cumulative use.
Device Story
Disposable nebulizer set; pneumatic jet nebulizer; uses external air compressor to aerosolize liquid medication; delivers aerosol directly to patient via mouthpiece for inhalation. Used in hospital environments; operated by healthcare professionals. Device consists of nebulizer jar, hollow tube, and mouthpiece. Transforms liquid medication into aerosol mist; particle size (MMAD) and respirable dose metrics comparable to predicate devices. Benefits patient by facilitating targeted respiratory drug delivery. Single-use, sterile, <24-hour cumulative duration.
Clinical Evidence
No clinical data. Substantial equivalence supported by bench testing, including particle size distribution (MMAD), total dose delivered, and total respirable dose measurements compared against predicate devices. Biocompatibility testing performed per ISO 10993-1, -5, -7, and -10.
Technological Characteristics
Pneumatic jet nebulizer; materials include PP (nebulizer bottle, mouthpiece, CPA) and PVC (oxygen/corrugated tubing). Sterilized via Ethylene Oxide (EO) per ISO 11135-1. Operates at 4-8 l/min flow rate and 700 Kpa pressure. Biocompatibility compliant with ISO 10993 series. No software or electronic components.
Indications for Use
Indicated for adult patients, including those with asthma, in hospital environments for the administration of aerosolized medication. Not for transport use. Single use, less than 24 hours cumulative duration.
Regulatory Classification
Identification
A nebulizer is a device intended to spray liquids in aerosol form into gases that are delivered directly to the patient for breathing. Heated, ultrasonic, gas, venturi, and refillable nebulizers are included in this generic type of device.
