  • An oxygen concentrator unit is a device that adsorbs nitrogen and other gases from air leaving oxygen and argon enriched air.
  • Oxygen concentrator units that can produce a gas made up of 93% oxygen are well known.
  • Each oxygen concentrator unit has a molecular sieve, such as a synthetic zeolite, which captures nitrogen molecules at a rate dependent upon the pressure of the air whilst travelling through the sieve. Therefore, as the oxygen concentrator units are connected to a vent via the changeover valve 16, the decrease in pressure within the concentrator unit forces the sieve to release the adsorbed nitrogen, whereby the sieve becomes re-usable and saturation may be avoided.

  • the ECU 36 thus controls the spool's position dependent upon the flow rate required at the outlet of the system while supplying the highest percentage of oxygen- enriched air as possible. Since two oxygen concentrator units 18a, 18b are used to supply air to the outlet, a higher flow rate from the outlet can be maintained for longer periods of time. Furthermore, when the oxygen-enriched air stored in the reservoir tank is used beyond a predetermined amount, the reservoir tank 20 can be filled at an increased rate.
  • the oxygen enriched air produced by the oxygen concentrator units 18a, 18b are fed by nylon tubing to a pressure control valve 38.
  • the pressure control valve 38 has a spool, which can be in one of two positions.
  • the first position blocks the feed from the first oxygen concentrator unit 18a and allows the oxygen-enriched air from the second oxygen concentrator unit 18b to the reservoir tank 20.
  • the first oxygen concentrator unit 18a provides oxygen enriched air to the reservoir tank 20 and the supply from the second oxygen concentrator unit 18b is blocked.
  • the ECU 36 also controls the pressure control valve 38.
  • the spools in the pressure control valve 38 and the changeover valve 16 are moved simultaneously so that one oxygen concentrator unit 18a; 18b is supplying the oxygen enriched air and the other oxygen concentrator unit 18b; 18a is removing the nitrogen adsorbed by the sieve. Furthermore, the oxygen enriched air between the oxygen concentrator unit 18a; 18b purging the nitrogen from the sieve and the pressure control valve 38 is sucked back through the oxygen concentrator unit 18a; 18b helping to remove the released nitrogen.
  • Nylon tubing connects the pressure control valve to the reservoir tank. There is provided a one-way valve 40 in the nylon tubing to ensure that oxygen enriched air in the reservoir tank 20 does not flow back through the system 10.
  • the reservoir tank 20 holds a predetermined amount of enriched air to be used during a treatment. Whilst the oxygen from reservoir tank 20 is being u sed, oxygen i s concurrently being s upplied f rom the two oxygen concentrator units 18a, 18b. If there were only one oxygen concentrator unit 18a; 18b, there would not be a continuous flow of air to the reservoir tank 20, as the concentrator unit would have to adsorb nitrogen supplying air and to release nitrogen periodically not supply air.
  • the oxygen-enriched air in the reservoir tank 20 is allowed to leave via an outlet valve 22.
  • the outlet valve 22 controls the gas gun 24, 26 which is to be used during the treatment and can be controlled manually. It should be noted that only one gas gun 24, 26 could be used at any one time.
  • the first gas gun 24 supplies a gas with a fixed oxygen concentration of 93%.
  • the flow rate through this gun 24 is fixed so that such a percentage is always achieved at the expense of the pressure.
  • the second gun 6 supplies a gas which is approximately 80% oxygen but at a higher pressure than that produced by the other gun 24.
