The DeVilbiss iFill is a home filling station for convenient and portable oxygen therapy. The iFill unit extracts purified oxygen from room air and pressurises it to fill oxygen cylinders quickly and conveniently in the home. An oxygen cylinder is connected to the top of the unit and rests securely in place until filling is complete. There are four sizes of cylinders available and for the smaller model an adapter is provided to ensure correct positioning of the cylinder. One of the key features of the iFill home filling station is the possibility to top up and re-fill cylinders as often as needed. The iFill cylinders can also be supplied with a PulseDose oxygen conserver, which provides a precise burst of oxygen at a relatively high flow rate on inhalation when it is most needed. This ensures the patient receives the optimum amount of oxygen whilst increasing the length of time the cylinder can be used for before refilling is required.
