### IV. Device Description
The Pulmogine® Vibrating Mesh Nebulizer, whose dimensions are 74 mm (L) x 46 mm (W) x 96 mm (H), is a small, dumbbell-shaped, handheld, and internally powered general-purpose nebulizer which utilizes vibrating mesh technology to generate aerosol. The Pulmogine® Vibrating Mesh Nebulizer is designed for a single patient, multiple uses, and mainly composed of a Main Unit and a Medication Reservoir.
The Main Unit contains the control circuitry and the firmware to control the vibrating mesh module in the Medication Reservoir and is powered by 2 AA alkaline batteries or an AC adaptor.
{4}------------------------------------------------
The Medication Reservoir contains the nebulizing module (mesh) where the liquid medication will be turned into aerosols. The prescribed medication is added into the reservoir with ten (10) ml of medication capacity, nebulized, and inhaled through the aerosol port.
The Pulmogine® Vibrating Mesh Nebulizer generates aerosol from liquid medication during turning on through pressing ON/OFF button and turning off when pressing ON/OFF button again, auto-turn off when no liquid detected, or 10-minute session completed. There are different LED lights to monitor the status and operating condition of the nebulizer: green indicates power on and normally working, yellow flash indicates low power caution, and constant yellow indicates shut-off due to too low power.
### V. Indications for Use
The Pulmogine® Vibrating Mesh Nebulizer is a system designed to aerosolize liquid medications for inhalation by the patient. The device may be used with pediatric (5 years and older), defined by the prescribed medication, and adult patients in hospital / institutional settings, home care use, schools, and long-term care facilities.
