The OX-A Series Oxygen Concentrator is a medical device designed to provide supplemental low-flow oxygen therapy in various settings, including homes, nursing homes, and patient care facilities. It operates by separating oxygen from room air, delivering high-purity oxygen through an oxygen outlet. The concentrator is electrically operated and is available in two models: OX-10A and OX-5A, offering different oxygen delivery rates.
Function Description
The primary function of the OX-A Series Oxygen Concentrator is to supply a continuous flow of oxygen to individuals who require supplemental oxygen due to respiratory or heart conditions. It achieves this by drawing in ambient air, filtering it, and then concentrating the oxygen before delivering it to the user via a nasal cannula, catheter, or face mask. The device is intended to improve symptoms such as headaches, drowsiness, confusion, fatigue, or increased irritability caused by insufficient oxygen intake from room air alone.

Usage Features
Front View Components:
- Power Switch (I=ON, O=OFF): Controls the unit's power.
- Circuit Breaker: Resets the unit after an electrical overload shutdown (on selected units).
- Humidifier Holder: Secures the humidifier bottle.
- Oxygen Outlet: The port from which oxygen is dispersed.
- Flow Meter Control Button ("M"): Adjusts oxygen flow rate in 0.5 LPM increments.
- Timing Setting ("+" / "-"): Adjusts operating time in 30-minute steps.
- Monitor: Displays oxygen purity status and hour meter.
- Green Power Light: Illuminates when the concentrator is operating.
- Normal Oxygen (Green) Light (Optional): Indicates normal oxygen concentration.
- Low Oxygen (Yellow) Light (Optional): Indicates low oxygen output concentration (82%+/-3%).
- Red Service Required Light: Illuminates when service is needed, prompting contact with the OXTM provider.
- Castors: For mobility of the unit.
Back View Components:
- Air Filter: Prevents dirt, dust, and lint from entering the unit.
- Product Specification Label: Contains model and serial information.
- Exhaust: Releases processed air.
- Power Cord and/or IEC Power Connector: Connects the unit to an electrical outlet.
Operation:
- Placement: Position the unit near an electrical outlet, at least 6 inches (16 cm) from walls, draperies, or other objects to ensure proper airflow. Keep it at least 5 feet (1.6 m) away from hot, sparking objects or open flames.
- Oxygen Tubing Connection: Attach oxygen tubing directly to the connector or to a humidifier bottle if prescribed.
- Humidification (if prescribed): Fill the humidifier bottle with distilled water (do not overfill) and attach oxygen tubing to its outlet fitting.
- Power On: Press the power switch to "On." The Power light will illuminate, and the Service Required light and audible alarm will briefly activate.
- Flow Rate Check: Ensure the flow meter ball is centered on the line corresponding to the prescribed flow rate. Adjust with the flow meter knob (clockwise to decrease, counterclockwise to increase).
- Oxygen Purity Monitoring: The device includes an oxygen monitoring system.
- Green LED: Indicates acceptable oxygen concentration (≥82%).
- Yellow LED: Indicates low oxygen concentration (82%~70%). If this light illuminates, switch to a reserve oxygen system and contact your OXTM provider.
- An intermittent audible signal will alarm if oxygen purity continues to drop.
Safety Features:
- DANGER - NO SMOKING: Oxygen causes rapid burning. Smoking is prohibited near the concentrator or a person using oxygen therapy.
- WARNING: Oxygen therapy can be hazardous; medical advice is recommended before use.
- Circuit Breaker: Protects against electrical overload.
- Patient Alert System: Sounds an alarm if the unit loses electrical power or malfunctions, signaling the user to switch to a reserve oxygen system.
Maintenance Features
General Care:
- No Lubricants: Do not use lubricants, oils, or grease on the unit.
- Power Off: Always turn the unit "off" before performing any cleaning procedures.
Oxygen Humidifier (Reusable Bottles):
- Daily Cleaning: If humidification is prescribed, clean the humidifier bottle daily.
- Cleaning Procedure:
- Wash with hot water and dishwashing detergent.
- Soak in a solution of one part white vinegar to three parts hot water for 30 minutes for germicidal action.
- Rinse thoroughly with warm tap water and refill with distilled water. Do not overfill.
Cannula, Mask, and Tubing:
