The
medical oxygen concentrators have been one of the most notable
breakthrough developments in the long-term oxygen therapy support. An
oxygen concentrator is an electrically operated medical device used
to provide purified or concentrated oxygen to a patient seeking
oxygen therapy. These devices work on principle of pumping air into
the device which then separates oxygen and deliver it to patients in
a continuous manner. Medical oxygen concentrators use rapid swing
adsorption method in which atmospheric nitrogen is adsorbed on an
adsorbent such as zeolite mineral leaving oxygen as the primary gas.
Oxygen
concentrators are considered as safer, easy to use and inexpensive
devices compared to compressed oxygen cylinders. These devices are
often prescribed to patients suffering from chronic pulmonary
diseases such as severe chronic obstructive pulmonary disease (COPD).
Couple of decades ago, there were only stationary oxygen
concentrators which were fairly bulky in size. These heavy oxygen
concentrators limited the patient mobility and this problem was later
solved by the development of portable oxygen concentrators (POCs)
which allow free movement for the patient making it possible for
oxygen patients to take their oxygen as and when required no matter
wherever they wish to go. The commercially available portable
medical oxygen concentrators weigh as less as 2-3 kg. Some of the
commercially available medical oxygen concentrators include Airstep
Freestyle, Delphi RS-00400, DeVilbiss Healthcare iGo, Inogen One G2
and Inogen One G3, Inova Labs LifeChoice Activox, Invacare XPO2,
Respironics EverGo, and SeQual Eclipse. These devices are also used
by mountaineers and people travelling to places where oxygen is
inadequate amount. Inova labs recently introduced its new portable
medical oxygen concentrator - LifeChoice Activox 4L which uses
technology to track user’s inhalation rate and breathing pattern to
deliver oxygen.
Some
of the major factors expected to drive the market for medical oxygen
concentrators include its ability to provide oxygen under all
circumstances and worldwide aging population coupled with COPD and
other respiratory diseases. Advantages associated with these devices
such as they weigh less, easy to use and more affordable are also
predicted to drive the market further. WHO suggests that
approximately 65 million people are suffering from moderate to severe
chronic obstructive pulmonary disease across the globe. In 2005, an
estimated 3 million people died because of COPD. North America was
observed to be the leading markets in oxygen cylinder market because
of the number of hospitals, large number of alternate care facilities
and high consumption of portable medical oxygen concentrators. Europe
region is second leading market for these devices due to high
consumer awareness and approval by regulatory authorities of these
regions. FAA (Federal aviation Administration) approved the onboard
use of certain portable oxygen concentrator. In Asia-Pacific, Japan,
India, China and Australia are the leaders in the market for medical
oxygen concentrators. In Rest of the World (RoW), countries such as
Mexico and Brazil witnessed market growth along with the countries in
the Middle East countries. The market outlook for these devices is
positive and the region is expected to witness a substantial growth
in coming years due to continuously increasing healthcare expenditure
in the region.
Some
of the major companies operating in this market are Inogen, Inc.,
Teleflex Incorporated, Philips Healthcare (Philips Respironics),
AirSep Corporation, DeVilbiss Healthcare, LLC, Invacare Corporation,
O2Concepts, Covidien plc, Oxlife, Vygon, Nidek Medical, Inova Labs,
