Mallinckrodt HELIOS – Case Study

Portable Oxygen Conserver Provides COPD Patients a 10 Hour Supply in an Ultra-compact Package.


The HELiOS® Personal Oxygen System is designed for the ambulatory patient in a home care environment. It is the smallest and lightest portable liquid oxygen system on the market that lasts up to 10 hours. The unit is ergonomically designed with an integrated handle and improved balance compared to competitive devices.

HELiOS was originally developed for Puritan-Bennett® (who became Nellcore Puritan-Bennett®, Mallinckrodt®, and finally Tyco®). Omnica continued as the development partner through the   restructurings, and incorporated Puritan-Bennett's original internal components and core    technology into a entirely re-imagined form factor. The result was an ultra compact package with an innovative design, aesthetics, and efficiency that initiated industry-wide growth in the use of liquid oxygen-based delivery devices. Sales boosted the company's entire product line with a market penetration that significantly exceeded the manufacturer's projections. The award winning device is now marketed by CAIRE® Inc. under the names HELiOS Plus & Marathon®.


Omnica was hired to performed competitive benchmarking studies, determine the state of the art for personal oxygen delivery systems, and design and build a product that incorporated their best features. Incidentally, one of our senior industrial designers had worked on the original Puritan-Bennett device, which gave our team valuable insight when we developed the HELiOS oxygen conserver. Our technical input consisted of industrial design, mechanical engineering, human factors, ergonomics, and design for manufacture.
