With its small volume, light weight, and turning casters for easy mobility, the GHM-OC3B is ideal for home oxygen therapy, hospitals, clinics, oxygen bars, plateau outposts, and fitness centers. Its stable performance, high safety, low noise operation, and user‑friendly interface make it a versatile and reliable choice for both clinical and home care settings.

This device is intended for use under the guidance of a healthcare professional. Not a substitute for professional medical advice.

Key Features

💨 High‑Purity Medical‑Grade Oxygen (93%±3%)

The GHM-OC3B uses high‑quality molecular sieve and PSA (Pressure Swing Adsorption) technology to produce oxygen with a concentration of 93% ± 3%. Within approximately 30 minutes of startup, the device reaches its rated oxygen output of 3L/min with an oxygen content of ≥90%. This ensures patients receive the therapeutic oxygen levels prescribed by their healthcare provider.

📊 Adjustable Flow Rate (0.5–3 L/min)

The device offers an adjustable oxygen flow rate from 0.5 to 3 L/min, allowing healthcare providers and patients to customize oxygen delivery according to individual therapeutic requirements.

🩸 Integrated SpO₂ & Pulse Rate Monitoring

By connecting the included accessory, the GHM-OC3B can measure and display blood oxygen saturation (SpO₂) and pulse rate in real time, allowing patients and clinicians to monitor oxygen therapy effectiveness continuously.

🛡️ Comprehensive 4‑Function Safety Alarm System

Patient safety is paramount with the GHM-OC3B's multi‑layer alarm system:

• Power failure alarm – Alerts when power is interrupted

• High/low pressure protection alarm – Warns of abnormal pressure levels

• Low flow rate alarm – Notifies when flow drops below the set level

• High temperature alarm – Protects against overheating

🔧 Built‑In Filtration for Clean Oxygen

The device features built‑in filters that purify the incoming air, ensuring that the oxygen delivered to the patient is clean and free from contaminants.

💡 Clear Visual Indicators

The GHM-OC3B features intuitive visual indicators for easy monitoring:

• Working indicator – Shows the device is operating

• Oxygen concentration status indicator – Confirms oxygen purity

• Oxygen flow indication – Displays current flow rate

⏱️ Timing & Accumulated Time Functions

The device includes convenient time management features:

• Timing shutdown function – Schedule therapy sessions

• Accumulated time function – Track total operating hours for maintenance planning

🔊 Low‑Noise Operation

The GHM-OC3B operates with low noise levels, minimizing disturbance to patients and family members during use—especially important for nighttime oxygen therapy.

🧊 Durable Molecular Sieve for Long Service Life

The device is equipped with imported molecular sieve with a service life of over 30,000 hours, ensuring years of reliable performance.

📦 Compact, Portable & Mobile Design

• Small in volume and light in weight – Easy to transport

🏥 Wide Clinical Applications

The GHM-OC3B has a wide application across multiple settings:

• Home oxygen therapy – Long‑term oxygen therapy (LTOT) for COPD and chronic respiratory conditions

• Hospitals & clinics – Inpatient and outpatient oxygen supplementation

• Oxygen bars & wellness centers – Recreational oxygen therapy

• Plateau & high‑altitude outposts – Oxygen supplementation in low‑oxygen environments

• Fitness & sports training centers – Post‑exercise recovery

The device is suitable for patients with cardiovascular disease, cerebrovascular disease, respiratory system diseases, altitude sickness, geriatric conditions, childhood respiratory infections, and carbon monoxide poisoning. It is also an excellent choice for students, office workers, athletes, seniors, and pregnant women for mental and physical recovery and general wellness.
