The mesh nebulizer utilizes the latest Vibrating Mesh Technology, which aerosol is generated by pushing liquid medications through fine holes in the newly developed metal alloy mesh. This is realized by a Nickel Alloy Vibrator (wafer-thin metal plate), oscillating at high frequency.
This unique technology offers the following features and benefits:
1.True pocket size for easy portability
2.Inhalation is possible at various angels
3.Soundless operation
4.Simple one-touch operation
5.Wide medication compliance
6.Low medication waste and residue
The mesh nebulizer works on 2×AA alkaline batteries, Nickel-Metal-Hydride (NiMH) rechargeable batteries or with a AC Power Adapter. Noise free, hand held size and lightweight, you can use it anytime and anywhere for inhalation therapy.
