Background and Identification
Puritan-Bennett Tyco Helios (stylized as HELiOS) is a personal oxygen concentration system designed by Puritan-Bennett. Puritan-Bennett is a producer of respiratory products and was initially a medical gas supplier. Puritan-Bennett is owned by Tyco Healthcare. An oxygen concentrator is a medical or industrial device that concentrates the oxygen from either ambient air or another gas supply. Oxygen concentrators selectively remove nitrogen and other gases from the air to provide an oxygen-enriched stream. The name HELiOS can refer to either the Reservoir or the Portable units. The H300 Portable name is also used for the portable unit.
The HELiOS oxygen system is designed as a portable system that can be used by patients up to 24 hours per day. Doctors often prescribe this HELiOS model for patients with Chronic Obstructive Pulmonary Disease (COPD). When using the H300 Portable model with a Standard HELiOS Reservoir, patients will usually require less than one liquid oxygen delivery each month. The HELiOS Universal Reservoir can be used to fill the H300 Portable model and the Puritan-Bennett Companion 500, Companion 1000, and Companion T portable oxygen concentrators.
The HELiOS oxygen concentration system includes a Portable patient unit and a Reservoir. Each component can work together or separately. Both portions of the system include the name “HELiOS” printed on the front of the device.
