(EN) A handheld system for delivering flavoured oxygen for recreational use by delivering a bolus of oxygen to the user each time the user puffs in on the mouthpiece. The system includes (1) the said mouthpiece, (2) a containment container for a flavor tablet,(3) a conserver to hold the oxygen until demanded, (4) an oxygen concentrator, (5) a rechargeable lithium battery, (6) a receptacle to accept a recharger cord....as well as containment valve (A) to contain the flavour until demand, containment valve (B) to allow flow from the consenter, containment valve (C) to contain the oxygen in the the concentrator until demand when the conserver is emptied.Activation sensor (7) becomes active upon the opening of valve (B) and has the oxygen concentrator bring air in from the air intake and concentrate the oxygen,When valve (C) opens (allowing the oxygen to flow into the conserver), the deactivation sensor (8) stops the concentrating process.The device now awaits the next puff in.
