Intended Use

The InspiraChamber® Anti-Static Valved Holding Chamber is intended to be used by patients who are under the care or treatment of a licensed health care professional. The device is intended to be used by these patients to administer aerosolized medication from most pressurized Metered Dose Inhalers, (pMDIs). Environment of use - Home, hospitals and clinics where patients may require the use of a holding chamber with pMDIs. The intended patient population is 3 years and older who have been prescribed pMDI medications.

Device Story

InspiraChamber is a valved holding chamber (spacer) used to facilitate inhalation of aerosolized medications from pMDIs. Device consists of a translucent housing, mouthpiece or face mask, and a one-way valve to prevent exhalation into the chamber. Includes an audible signal alert. Used in home, hospital, and clinical settings by patients prescribed pMDI medications (corticosteroids, anti-cholinergics, B2-sympathomimetics, non-steroidal chromones). Patient actuates pMDI into chamber; device holds aerosol for inhalation, improving drug delivery to upper and lower respiratory systems. Audible alert provides feedback on inhalation technique. Single-patient, multi-use device.

Clinical Evidence

Bench testing only. Comparative particle characterization performed using an 8-stage cascade impactor at 12 lpm and 28 lpm flow rates with three different pMDI medications (ProAir HFA, Atrovent HFA, QVAR 40). Metrics included Total Delivered Dose, Total Respirable Dose (0.5-5.0 microns), MMAD, and GSD. Results demonstrated equivalent performance to the predicate device.

Technological Characteristics

Valved holding chamber with translucent housing, mouthpiece/face mask, and one-way valve. Includes audible signal alert. Non-sterile, single-patient, multi-use. Materials tested per ISO 10993 (cytotoxicity, sensitization, intracutaneous irritation). Anti-static surface properties. Mechanical testing includes drop tests and simulated life cycle/cleaning cycles.

Indications for Use

Indicated for patients 3 years and older under the care of a licensed healthcare professional requiring administration of aerosolized medication from most pressurized Metered Dose Inhalers (pMDIs).

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.

- · Anti-cholinergics and B2-sympathomimetics (bronchodilater medications)
- · Non-steroidal chromones (DNCG)

It is a single patient, multi-use, non-sterile device.

#### Indications for Use:

The InspiraChamber® Anti-Static Valved Holding Chamber is intended to be used by patients who are under the care or treatment of a licensed health care professional. The device is intended to be used by these patients to administer aerosolized medication from most pressurized Metered Dose Inhalers, (pMDIs).

Environment of use - The proposed device may be used in home, hospitals and clinical settings where patients may require the use of a holding chamber with pMDIs.
