Technical Specifications:

• Power Source: DC 5 V, 1 A input via USB.

• Internal Battery: 3.7 V, 1,200 mAh lithium battery.

• Operating Frequency: 110 kHz ± 10 kHz.

• Nebulization Rate / Efficiency: ≥ 0.2 mL/min.

• Particle Size Distribution: Over 60% of the aerosol particles are < 6 μm in diameter; the median particle size is approximately 4.5 μm ± 25%.

• Medication Cup Volume: ~8 mL capacity.

• Noise Level: Less than 50 dB (A-weighted), making it very quiet during operation.

• Dimensions: 49 mm × 69 mm × 115 mm.

• Weight: ~125 g (excluding battery).

• Service Life: The main unit is rated for ~5 years under typical usage.

• Operating Environment:

  • Temperature: 5 °C to 40 °C

  • Relative Humidity: 25% – 95% (non-condensing)

  • Atmospheric Pressure: 70 to 106 kPa

  • Storage / Transport Conditions:

  • Temperature: –20 °C to +55 °C

  • Relative Humidity: 25% – 95% (non-condensing)

Features / Advantages:

• Portable and Lightweight: Very convenient for mobile use due to compact size and internal battery.

• Quiet Operation: The sound level is very low (< 50 dB), enhancing comfort for patients, especially during night-time or in shared spaces.

• One-Key Operation: Simplified control with a single button for start/stop and basic control.

• Auto-Cleaning Function: Built-in cleaning mode reduces maintenance burden and helps maintain mesh performance.

• LED Indicator: Visual feedback for power / operation status.

• USB Rechargeable: Using USB power makes it very adaptable for home or travel charging.

Regulatory / Quality:

• According to regulatory listing, the Believia MNB-05 is classified in Pakistan as a Class B medical device, with a shelf-life of 5 years.

• Manufacturer: Reported as Cofoe Medical Technology Co., Ltd (based on device registration).

Intended Use / Application:

• Designed for aerosolized delivery of liquid respiratory medications — ideal for maintenance and rescue inhalation therapy for various pulmonary conditions.

• Suitable for pediatric and adult patients due to its fine particle size and ease of use.

• Because of its portability, it’s particularly useful for on-the-go therapy, travel, and settings where traditional compressor nebulizers are impractical.

Limitations / Considerations:

• Mesh technology, while efficient, may be more susceptible to clogging or wear if used with viscous or particulate medications; adherence to cleaning protocols is essential.

• The maximum nebulization rate (≥ 0.2 mL/min) might be slower than some high-flow compressor nebulizers — treatment times may be longer for large doses.

• Requires periodic charging — reliance on internal battery means usage is limited to battery capacity between charges.

• For long-term high-frequency use, mesh longevity should be considered; replacement or maintenance may be needed.
