Key Features

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

The GHM-CONTEC21-7 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. This ensures patients receive the therapeutic oxygen levels prescribed by their healthcare provider.

📊 Adjustable Flow Rate (0.5–7 L/min)

The device offers an adjustable oxygen flow rate from 0.5 to 7 L/min, allowing healthcare providers and patients to customize oxygen delivery according to individual therapeutic requirements.

🫁 Built‑in Nebulization Function

By connecting the optional nebulization accessories, the GHM-CONTEC21-7 can also function as a nebulizer for respiratory medication delivery. This dual‑function capability makes it an all‑in‑one respiratory therapy solution for patients with asthma, COPD, and other respiratory conditions.

🩸 Optional SpO₂ & Pulse Rate Monitoring

With optional accessories, the GHM-CONTEC21-7 can measure and display blood oxygen saturation (SpO₂) and pulse rate (PR) —allowing patients and clinicians to monitor oxygen therapy effectiveness in real time.

🛡️ Comprehensive 8‑Function Safety Alarm System

Patient safety is paramount with the GHM-CONTEC21-7's multi‑layer alarm system, which triggers automatic shutdown in critical situations:

• 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

• Current overload protection – Automatic shutdown on overload

• Compressor high temperature shutdown – Prevents compressor damage

• Compressor error detection – Monitors compressor function

🔧 Built‑In Filtration for Clean Oxygen

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

⏱️ Timing & Accumulated Time Functions

The GHM-CONTEC21-7 includes a timing shutdown function for scheduled therapy sessions, plus an accumulated time function to track total operating hours for maintenance planning.

💡 Clear Visual Indicators

The device 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

🔇 Low‑Noise Operation (≤52 dB)

With an operating noise level of ≤52 dB(A) , the GHM-CONTEC21-7 operates quietly—minimizing disturbance to patients and family members during use.

📦 Compact, Portable & Mobile Design
