Homefill oxygen devices or oxygen transfill systems are popularly known as Oxygen Refill Systems. They are portable oxygen refill devices that are used at home to fill empty oxygen tanks. By using oxygen concentrator technology, the concentrated oxygen is extracted from room air to oxygen refill machines. This gives the user an unlimited refill of oxygen. The refill system then pressurizes the concentrated air to fill the oxygen cylinders. Patients get more liberty as they don’t have to depend on oxygen vendors for a refill.

Why use an Oxygen Refill System?

  • Greater freedom and independence for oxygen patients
  • Saves a lot of precious time
  • Saves money spent on pickups and deliveries
  • Gives the comfort of easy time scheduling
  • Independence from a third party
  • Assurance of oxygen availability at all times

When to use Home Oxygen Refill Systems?

An empty oxygen cylinder can be refilled at any time. It does not matter if the patient is away shopping or taking a nap. There are no restrictions on refilling the cylinder. Turn on the machine and attach the empty cylinder to refill the oxygen tank at home. After refilling, the portable oxygen tank can be used instantly or can be kept in as a reserve. Oxygen refilling also saves the space required for storing the number of reserve tanks. Always make sure to have backup tanks filled and ready to go in case of an emergency.

Where to use an Oxygen Refill Machine?

An oxygen refill system can be used at places with a regular supply of 110-120-volt electricity. Oxygen refill units can be used anywhere that electricity is available. They are ideal for home, office, and even hotel use

The Invacare HomeFill CGA870 Post Valve Cylinders perfectly fit the Invacare HomeFill Oxygen System. These are specifically designed to facilitate the active users of the HomeFill System with a regular oxygen supply. They are manufactured to store supplemental oxygen for use with a CGA870 post-valve compatible conserver or regulator. These Cylinders are used by patients who may have difficulty extracting oxygen from the air they breathe. Oxygen duration can vary depending on the oxygen needs of the user. 

It is a lightweight, aluminum oxygen cylinder that has two parts to it, one is the Toggle Valve and another is Cylinder Fill Port. The user can fill the Invacare Homefill tanks by following these steps.

Before you try filling the cylinder please check the cylinder pressure, rotate the toggle valve clockwise to close it properly, and detach the regulator (conserver). Remove the post valve cover (situated on the cylinder) and the connector fillport covers (situated on the compressor). There is a ring-like structure on the compressor unit, push the ring down for a moment to reset the connector. Get hold of the cylinder assembly, and place the cylinder in the compressor cradle. Line up the cylinder fillport with the connector fillport. Now pull the ring up and push the cylinder assembly down. This way you can connect the cylinder fillport to the connector fillport. Switch ON the compressor power button, once the cylinder is full, press the switch off. Hold the cylinder assembly, with your other hand grasp the ring present on the connector fillport and push it down. After that, remove the cylinder assembly from the connector fillport by lifting it up. Once the cylinder is disconnected, release the ring. Then separate the cylinder from the cradle. Now place the fillport covers back in their places and install the CGA870 Post valve conserver. Finally, put the toggle valve back and rotate it anti-clockwise.

How to refill Oxygen Tanks?

  1. Place an oxygen refill machine on top of an oxygen concentrator and connect them to each other. Plug them into an electrical socket and press the power button to turn them on.
  2. Connect your oxygen tank or cylinder to the refill machine. Ensure that the tank's oxygen conserver or regulator is turned off. If you are not using a conserver or regulator to fill the oxygen cylinder, verify that the cylinder valve is closed to ensure proper filling.
  3. Remove any protective caps from the oxygen tank. When not in use, replace these protective caps to prevent dust buildup.
  4. Gently pair the cylinder fill port of the refill machine with the cylinder. When the cylinder is secured to the oxygen compressor, you will hear an audible click.
  5. Press the fill button to begin filling your oxygen tank. The filling might take some time, depending on the size of your cylinder.
  6. You will be indicated when the tank is full. Most machines automatically shut off when the canister is full.
  7. Turn off the power button and release the cylinder from the oxygen refill system.

Oxygen transfilling systems are integral to making a patient more independent, compliant and healthy.
