Market Insights:

According to the World Bank study report the rise in air pollution and particulate matter such as sulfur dioxide, ozone, 2.5micron particulate matter, sand etc., due to rapid industrialization and urbanization has resulted in the surge of chronic pulmonary diseases. As per the World Health Organization report in 2015 approximately 3 million people died due to chronic pulmonary obstructive diseases which represents 5% of all the deaths globally.

Presently portable oxygen concentrator holds the largest market share due to key drivers such as increasing public health awareness, inherent features of oxygen concentrators such as lightweight, robustness, easy installation to main air ventilation supply etc. Additionally portable oxygen concentrators finds huge application in places such as airports, shopping malls, commercial airlines, and offices. Fixed oxygen concentrators will grow rapidly as it grants quick access to the oxygen concentrators as the auxiliaries are prefabricated so handling is easy and is of prime importance in elderly healthcare centers at night when the elderly patients with pulmonary complications are sleeping.

Homecare enjoys domination owing to increasing number of households addicted to smoking results in the demand for fresh air enriched in oxygen, promotes early patient recovery due to comfort and provides reinforcement care from the patient’s family and caregivers. Long term rehabilitation and nursing will record a steady growth on account of increasing high patient volume in these centers over the past decade, rise in geriatric population suffering with chronic pulmonary diseases requiring long term medical intervention.

Key Market Movements:

  • Rising prevalence of chronic pulmonary diseases such as asthma, COPD, bronchitis and emphysema
  • Increasing public health awareness and disposable incomes in the developing nations to drive oxygen concentrators market growth
  • Supportive regulatory environment for oxygen concentrators products
  • Technological advancement in the components of oxygen concentrators will propel  market penetration for oxygen concentrators in the developing regions

How oxygen concentrators work

Oxygen concentrators typically use pressure swing adsorption (psa) technology and are used very widely for oxygen provision in healthcare applications, especially where liquid or pressurized oxygen is too dangerous or inconvenient, such as in homes or in portable clinics. For other purposes there are also concentrators based on membrane technology.

 

An oxygen concentrator takes in air and purifies it for use by people requiring medical oxygen due to low oxygen levels in their blood.oxygen concentrators are also used to provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants. Oxygen concentrators utilize a molecular sieve to adsorb gases and operate on the principle of rapid pressure swing adsorption of atmospheric nitrogen onto zeolite minerals and then venting the nitrogen. This type of adsorption system is therefore functionally a nitrogen scrubber leaving the other atmospheric gases to pass through. This leaves oxygen as the primary gas remaining. Psa technology is a reliable and economical technique for small to mid-scale oxygen generation, with cryogenic separation more suitable at higher volumes and external delivery generally more suitable for small volumes.

 

At high pressure, the porous zeolite adsorbs large quantities of nitrogen, due to its large surface area and chemical character. After the oxygen and other free components are collected the pressure drops which allows nitrogen to desorb.

 

An oxygen concentrator has an air compressor, two cylinders filled with zeolite pellets, a pressure equalizing reservoir, and some valves and tubes. In the first half-cycle the first cylinder receives air from the compressor, which lasts about 3 seconds. During that time the pressure in the first cylinder rises from atmospheric to about 2.5 times normal atmospheric pressure (typically 20 psi/138 kpa gauge, or 2.36 atmospheres absolute) and the zeolite becomes saturated with nitrogen. As the first cylinder reaches near pure oxygen (there are small amounts of argon, co2, water vapour, radon and other minor atmospheric components) in the first half-cycle, a valve opens and the oxygen-enriched gas flows to the pressure equalizing reservoir, which connects to the patient’s oxygen hose. At the end of the first half of the cycle, there is another valve position change so that the air from the compressor is directed to the 2nd cylinder. The pressure in the first cylinder drops as the enriched oxygen moves into the reservoir, allowing the nitrogen to be desorbed back into gas. Partway through the second half of the cycle, there is another valve position change to vent the gas in the first cylinder back into the ambient atmosphere, keeping the concentration of oxygen in the pressure equalizing reservoir from falling below about 90%. The pressure in the hose delivering oxygen from the equalizing reservoir is kept steady by a pressure reducing valve.

 

Older units cycled with a period of about 20 seconds, and supplied up to 5 litres per minute of 90+% oxygen. Since about 1999, units capable of supplying up to 10 lpm have been available. Source: wikipedia
