① Safety Precautions

1. Danger

Risk of electric shock. Do not disassemble the machine.

For technical assistance, contact RESPIREASY.

Warning – Fire & Explosion Hazards

Oxygen-enriched environments increase fire risk. No Smoking.

Keep all flammable materials away from the oxygen concentrator; avoid placing it in the same room.

Oil, grease, or oily substances can ignite when exposed to pressurized oxygen. Keep them away from tubing, connectors, and oxygen outlets.

Operating Guidelines

Run the oxygen concentrator for at least 30 minutes per use for best performance. The machine is only for oxygen supply, and the oxygen concentration will be up to 90% when air outlet reaches its nominal flow.  

Do not turn on or off frequently, To restart the machine after turning off, no less than 5 minutes are necessary (namely, exhaust internal

                                                                     4

gas of the machine completely, for if air compressor turns on with pressure, its life will be shortened )

Turn up the flow meter switch immediately when power switch is turned on.

Place the unit in a well-ventilated indoor area, away from direct sunlight, with at least 10 cm clearance from walls, furniture, or fabrics.

Do not block the air inlet or place the unit on soft surfaces (e.g., beds, sofas). Keep away from lint, hair, or dust.

Use only a registered, anti-crush nasal cannula.

Handling & Maintenance

Never move the unit by pulling the cord.

Always unplug the unit when not in use.

Do not insert foreign objects into openings.

It should be replaced by the manufacturer original oxygen accessories (~oxygen filter, humidifier tank, power cord, fuse, oxygen tube oxygen cannula...)

Humidifier Use

Fill the humidifier cup only with clean, pure water. Do not overfill to avoid spillage.

Follow usage instructions when adding or cleaning water.

Water & Moisture Precautions

Do not use the oxygen concentrator while bathing. If continuous oxygen is required, place the unit at least 2 meters away from the bathroom.

                                                                          5

Do not use, touch, or store the oxygen concentrator in wet environments. If the unit falls into water, unplug immediately and do not reuse until inspected.

 

 

② Product Features

Ⅰ.Overview 

RESPIREASY RE-M5L/ RE-M10L/ RE-M20L medical oxygen concentrator is a device that extracts oxygen from atmospheric air. 

It will typically be an electrically-powered molecular sieve (artificial zeolite) used to separate nitrogen from ambient air. It could be applied widely in the hospitals at all different level, clinics, health centers and health care for the old person, mental workers and students, etc.. Whether the user is professional or not, the users could operate the oxygen concentrator by themselves after reading this user’s manual.

The oxygen concentrator can supply 1-2 patients simultaneously, with steady oxygen flowing out, safe and reliable, low cost, adjustable flow. The key parts of  the concentrator adopt anti-tiring and anti-aging design, and the planned life of the whole concentrator reaches up to 20,000 hours or 5 years, whichever comes first.

                                                                        6

Ⅱ. Key Technical Specifications

 

Ⅲ. Working Principle

The oil-free compressor supplies compressed air to the rotary valve, which alternately directs flow to two molecular sieve beds (A and B).

Adsorption phase: When air enters one bed, nitrogen is adsorbed by the molecular sieve while oxygen passes through to the flow meter for delivery.

                                                                   7

Desorption phase: Simultaneously, the other bed undergoes regeneration as residual gas is vented through the exhaust silencer.

By switching between the two beds in cycles, nitrogen is continuously removed, and high-purity oxygen is stably produced from ambient air.

④ Installation and Use

I. Preparation

1, Unpack the oxygen concentrator and remove all protective materials.

2, Connect the oxygen delivery tube:

• l One end to the humidifier bottle outlet, the other to the nasal cannula or oxygen outlet.

• The unit can be used with or without the humidifier bottle filled with water. (Water only provides humidification and does not affect oxygen concentration.)

                                                       9

3, To fill the humidifier bottle:

• l Unscrew the cap, add purified water up to the maximum level line, and tighten the cap.
• Secure the bottle in the fixed slot with the elastic strap.

4, Connect the power, put the plug of power line connected with the power AC110V,turn on the power switch.

5, Adjust well oxygen output flow according to the request, the maximum scale line of the flow meter is recommended oxygen absorbing flow (counter clockwise—on, clockwise—off, RE-M5L adjusted to 5L/min, RE-M10L adjusted to 10L/min,RE-M20L adjusted to 20L/min.

6, When finished, turn off the power, if there is discontinuous use, please unplug the power plug.

II. Oxygen Inhalation Operation

1. Turn the power switch to “I”, then press the “Oxygen Production” button on the control panel. The oxygen concentrator icon will light up, indicating it is in normal operation. While the concentrator is working, it will emit a “thud-- puff--” sound every few seconds, which is the normal sound of ventilation and exhaust. You can adjust the flow rate using the “Flow” button.

Note: The oxygen concentration will stabilize after approximately 30 minutes of initial operation. 

2. Connect one end of the nasal cannula to the oxygen outlet of the humidifier bottle and ensure the other end is properly worn by the patient to begin oxygen inhalation.

                                                               10

-- Adjust the oxygen inhalation time and flow rate according to medical advice.

-- After completing oxygen inhalation, turn off the oxygen concentrator and remove the oxygen delivery tube.

 

III. Nebulization Port (Optional, Applicable for High-Configuration Model)

1、Before turning on the machine, unscrew the nebulization port cap counterclockwise.

2、Connect one end of the catheter to the nebulization port. Please use as  needed or under the guidance of a qualified physician, and wear the nebulizer as required.

3、To power on, press the “Oxygen Production” button. Ensure the flow rate is set to 1L; the oxygen machine will switch to nebulization mode.

4、After nebulization is complete, press the “Oxygen Production” button to power off, disconnect the nebulizer tubing, and reattach and tighten the nebulization port cap. 

IV. Timer Setting

This machine has a timer function. If needed, press the “Timer” button on the display screen to adjust.

After turning on the machine, press the “Timer” button. Each press increases the timer by 30 minutes (or 1 hour, depending on model);

To cancel the timer, press the “Timer” button repeatedly until the display returns to “00”.

                                                                  11

V. Flow Adjustment

VI. Power Off

After use, first disconnect the oxygen delivery tube or connection from the humidifier outlet, turn off the power switch, and then unplug the power cord.

⑤ Maintenance and Care

Warning: Before Maintenance of  the Oxygen Concentrator, Disconnect the Power Supply.

·The oxygen concentrator should be placed in a dry, dust-free, and well- ventilated area. Ensure that the air intake and exhaust ports are unobstructed.

· Oxygen delivery devices (such as nasal cannula) should be used by designated individuals to ensure hygiene. 

I.Cleaning the Entire Unit

The exterior of the unit should be wiped clean at least once a month. First, disconnect the power supply, then use a clean, soft, slightly damp cloth or sponge to wipe it down. Do not allow liquid to seep into the seams of the casing. 

II. Cleaning or Replacing the Filter and Air Intake Sponge Filter

Cleaning and replacing the filters and air intake sponge filter is crucial for  protecting the compressor and molecular sieve, and for

                                                                       12

extending the lifespan of the oxygen concentrator. Please clean or replace them promptly.

* The oxygen filter should be replaced every 2 - 3 months

Warning:

·Do not operate the oxygen concentrator if the filter or air intake sponge filter  is not installed or is damp, as this can cause permanent damage to the machine.

1, Removing the Filter/Air Intake Sponge Filter:

The filter/air intake sponge filter is located at the back of the machine. 2, Cleaning &Replacing:

The expired oxygen filter may lead to RESPIREASY Oxygen Concentrator can not put out oxygen like it should be.

So the oxygen filter should be replaced the new one in time.
