A ventilator is an important mechanical ventilation device that replaces or assists people's breathing.
Delivering medical-grade oxygen with proven PSA technology, our portable continuous flow oxygen concentrator combines clinic-level performance with true on-the-go freedom. Engineered to extract ambient air and concentrate oxygen up to medically required purity (typically 90–95%) using advanced molecular sieve (PSA) systems, this continuous portable oxygen concentrator supports both daytime activity and uninterrupted night-time therapy.
Portable oxygen concentrators (POCs) work by filtering nitrogen from the ambient air to deliver concentrated oxygen directly to your respiratory system. These lightweight, compact devices are designed for mobility, allowing users to maintain their oxygen therapy anywhere, whether at home or on the go.
A continuous portable oxygen concentrator is a battery-powered medical device that extracts and purifies oxygen from the surrounding air, providing supplemental oxygen in either continuous flow or pulse dose modes. Its compact design makes it easy to transport and convenient for everyday use outside of the home.
*Oxygen Generation & Concentration
1) Extracts ambient air (21% O₂), removes nitrogen and impurities via molecular sieve technology (PSA: Pressure Swing Adsorption), and delivers 90-95% pure oxygen for medical use136.
2) Flow Control: Adjustable output (e.g., 1–10 L/min for home units; 0.5–5 L/min for portables)67.
* Dual Oxygen Delivery Modes
1) Continuous Flow: Steady oxygen supply (critical for sleep or severe respiratory failure).
2) Pulse Dose: Sensor-triggered bursts during inhalation (conserves battery, ideal for portable use)710.
* Real-Time Monitoring & Safety
1) Built-in oxygen concentration sensors (≥82% purity assurance) and alarms for low purity/power failure38.
2) Bluetooth-enabled apps (e.g., Nomad Health™) track usage, battery life, and purity710.
* Portability & Power Management: Flying with Your Portable Oxygen Concentrator
In today's world, oxygen therapy no longer means being confined to your home. Thanks to advancements in portable oxygen concentrator technology, you can now travel freely and even fly while maintaining your oxygen therapy. Modern portable oxygen concentrators are lightweight, FAA-approved, and designed to provide a continuous oxygen supply wherever your journey takes you.
1) Lightweight designs (e.g., 6.5 lbs for Belluscura DISCOV-R™) with rechargeable batteries (4–13 hours runtime)710.
2) FAA-approved for in-flight use610.
Key Advantages vs. Traditional Oxygen Tanks
| Feature | Oxygen Concentrators | Oxygen Tanks |
| Safety | No high-pressure/flammability risk | Explosion/cryogenic burn risk |
| Cost | Lower long-term cost (air as raw material) | Refill/logistics expenses |
| Mobility | Portable models enable outdoor/travel use | Heavy, limited mobility |
| Eco-Friendliness | Zero consumables; energy-efficient | Metal waste from cylinders |
| Convenience | 24/7 operation without refills | Frequent replacement needed |
Noise Reduction: Advanced models operate at <39 dB (library-quiet)710.
Humidification Integration: Built-in humidifiers prevent airway dryness during prolonged use48.
| Parameter | Medical-Grade | Portable (e.g., Belluscura DISCOV-R™) | |
| O₂ Output | Up to 10 L/min (continuous) | ≤2 L/min (continuous); 2000 mL/min (pulse) | |
| Weight | 35–50 lbs | 2–20 lbs | |
| Use Case | COPD, heart failure at home | Travel, active lifestyles | |
| Battery | Mains-powered; backup battery | 4.5–13 hours per charge |
Clinical Applications
* Chronic Respiratory Diseases
1) COPD/Emphysema: Long-term O₂ therapy improves survival and reduces hospitalization69.
2) Pulmonary Fibrosis: Alleviates hypoxemia during daily activities.
* Cardiovascular Support
Heart Failure: Enhances myocardial oxygenation, reducing cardiac workload89.
* Emergency & Perioperative Care
1) Post-Surgery: Prevents hypoxia during recovery9.
2) COVID-19/ARDS: Manages acute hypoxemia in mild-to-moderate cases6.
* High-Altitude & Mobility Aid
Prevents altitude sickness during travel; enables exercise for patients with O₂ dependency910.
Future Trends
AI Integration: Auto-adjusts flow based on SpO₂/activity levels9.
IoT Connectivity: Remote monitoring by clinicians via cloud platforms910.
Lightweight portable oxygen concentrator provide safe, cost-effective, and mobile oxygen therapy for chronic diseases, emergencies, and lifestyle needs. Their dual-flow technology, real-time monitoring, and portability redefine respiratory care across clinical and home settings. For technical details on specific models (e.g., noise/purity metrics), refer to manufacturer specifications
Continuous Flow vs. Pulse Dose Delivery
Portable oxygen concentrators deliver oxygen in two main ways:
· Continuous Flow: Supplies a steady, uninterrupted flow of oxygen, regardless of whether the user is inhaling or exhaling. This mode is often found in larger devices weighing over 10 lbs, as it requires more powerful components.
· Pulse Dose: Provides oxygen only when the user inhales, conserving both oxygen and battery life. Pulse dose models are generally smaller and lighter—around 6 lbs—and require a prescription specifying the appropriate settings for each user.
Dianya is dedicated to developing innovative portable medical devices that empower healthcare professionals and patients alike. Our advanced, compact solutions are designed to deliver hospital-grade performance anywhere — from clinical environments to home care settings.
