Abstract: A CPAP flow driver is adapted to split supplied breathable fluid into a first portion delivered to a venturi throat to generate a pressure drop to draw in ambient air to create a CPAP flow And a second portion that is delivered to a nebulizer to drive the nebulizer.

Abstract: A therapeutic face mask comprises a face-engaging portion and a single connector having a mask-engaging end and a single treatment-receiving end which has a single attachment mounting for detachably sealingly receiving a treatment attachment, such as an oxygen reservoir bag or a nebulizer. A one-way inhalation valve in the connector permits fluid flow from the treatment-receiving end to the mask-engaging end during inhalation and inhibits fluid flow in the other direction. The mask also includes a valve-governed exhalation port and an anti-asphyxia valve assembly configured to permit fluid flow from ambient to the face-engaging portion during inhalation only when inspiratory effort during inhalation exceeds fluid flow to the treatment-receiving end of the connector. Also provided is an oxygen reservoir bag having a neck shaped for removable coupling to a mating connector of a therapeutic face mask. An oxygen reservoir bag may have a metered-dose inhaler port defined in its neck.

Abstract: Apparatus for the administration of gases such as oxygen, anaesthetic gases, and the like, incorporating a chamber adapted to communicate with a face mask, a gas delivery conduit for delivering gas into the chamber, a control valve manually operable to start and stop delivery of gas thereto, a vent opening for intermittently venting the chamber to atmosphere for exhalation, a valve stem and a valve operating button thereon, the valve stem extending through the vent opening to the exterior of the chamber, a vent closure comprising the inner surface of the valve button, closing the vent opening when the button is operated to start delivery of gas to the chamber, a pressure relief valve communicating with the chamber for discharging to atmosphere in the event of an overpressure occuring therein, while the vent closure is in position closing the vent opening; a gas bypass connection connecting with the gas delivery conduit for receiving gas independently of the control valve; a gas bypass flow valve manually oper

Abstract: Apparatus for the administration of gases such as oxygen, anaesthetic gases, or the like, incorporating a chamber adapted to communicate with a face mask, gas delivery means for delivering gas into said chamber, valve means for intermittently discontinuing delivery of gas thereto, vent means for intermittently venting said chamber to atmosphere for exhalation, and, pressure relief valve means communicating with said chamber for venting the same to atmosphere in the event of an overpressure occurring therein.
