## Device Description:

The Portable Nebulizer (MBPN002) is a small, handheld general purpose nebulizer which utilizes vibrating mesh technology to generate aerosol.

### Modification:

The MicroBase Portable Nebulizer was modified to allow for connection to a 5 Volt Class II, IEC 60601-1 compliant external power supply. The device will still contain internal primary batteries. The power input jack interrupts (opens) the connection to the batteries when the external supply is plugged in so the batteries will not be connected to it (i.e., preventing them from charging).

When operating on battery power the Main unit converts the 3.0V nominal from the batteries to 15.0V for operation of the unit. The Main Unit thus operates on 15.0V regardless of power source (battery or external Power) there is no impact on nebulizing properties or performance.

There are no differences between the subject device and the predicate with respect to indications for use.

#### Components:

The Medication Cup contains the nebulizing module where aerosol will be generated. Prescribed medication is placed in the Cup, nebulized and inhaled via the integral mouthpiece.

The Medication Cup is single patient, multi-use. Cleaning is performed after each use by rinsing with distilled water and disinfected as described in the labeling via immersion in boiled water for 10 minutes.

The cup medication capacity is 6 ml.

The medication cup is identical to that cleared in K170916.

{4}------------------------------------------------

#### 510(k) Summary Page 2 of 6 September 14, 2018

The Main Unit contains the 2 "AA" batteries and firmware to control the vibrating mesh module in the Medication Cup. It is being modified to provide provision for external power from an IEC 60601-1 compliant power supply as described in Modification above.

Portable Nebulizer aerosolizes upon turning on by pressing the ON/OFF button and turns off by pressing again or automatically after treatment completion in 30 minutes. To monitor nebulization status and device operating condition, there are different LED colors shown. Normal working condition is indicated by a green while an orange color signifies a malfunction.

The Main Unit is identical to that cleared in K170916 except for the provision for external power from an IEC 60601-1 compliant power supply.

## Indications for Use:

The Portable Nebulizer (MBPN002) is a vibrating mesh nebulizer 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.

# Principle of Operation / Technology:

The Portable Nebulizer (MBPN002) operates by electrically activating piezoelectric ceramic actuator (PZT) which then transduces the vibration generated to the adjacent supporting plate and polymer mesh bearing numerous apertures. The vibration actively pushes out the liquid medication by physically breaking surface tension of the solution through mesh holes thereby achieving final nebulization. Aerosol generation can subsequently be modulated the vibration frequency that is controlled by the firmware stored within Main Unit to maintain a frequency of approximate 117 kHz, nebulization rate of > 0.25 ml/min and a power consumption of <1.5 W.

### 510(k) Summary Page 6 of 6 September 14, 2018

## Cleaning and Disinfection Validation

The modification does not affect the device design or materials as it relates to cleaning and disinfection. The predicate testing performed microbiological efficiency control tests to validate the nebulizer cleaning and disinfection methods in the labeling. Testing involved validation of: (1) a manual cleaning method and a thermal disinfection method. All testing concluded that the nebulizer could be cleaned and disinfected effectively by the listed methods

# Particle Characterization

Particle characterization performance is the same as the predicate device as the Main Unit operates at 15 V regardless of the power source: battery or AC power. Therefore there is no change in the aerosolization performance.

Particle size characterization (MMAD) was verified after two years of real-time aging using both cascade impactor technique and laser light scattering technique and is equivalent to that presented in K170916.

# Substantial Equivalence Conclusion

The indications for use, patient population, environment of use, technology principle of operation and performance of the modified device is identical to the predicate cleared under K170916 therefore we conclude that the modified device can be determined to be substantially equivalent to the predicate.
