A disposable oxygenating device is described for passively providing oxygen to a breathing patient. The device comprises a body and a collapsible bag coupled thereto, the body including first coupling means being couplable to a source of oxyge n. A second coupling means is couplable to an endotracheal tube, laryngeal mask o r similar device. A connector is connected to the bag and an oxygen duct is in fluid communication with the first coupling means, having an outlet orifice which in use delivers oxygen from the source of oxygen to inflate the bag with oxygen, an d an outlet. The arrangement is such that, in use, the oxygen causes inflation of the bag , and, during an inspiration cycle, oxygen from the bag passes through the second coupling means causing the bag to collapse or partly collapse and, during the expiration cycle, expiration products pass through the body and are expelled through the outlet. |
