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.

Mixing and dispensing apparatus and methods for use with, e.g., a multi-component reactive material process is disclosed.

A respiratory face mask is provided suitably sized and configured to engage at least the nose portion and mouth portion of a patient's face. Gas from a gas supply and scavenging set normally used in dentistry is operatively coupled to the mask via a breathing circuit to supply fresh gas and evacuate exhaled waste gas. A gas flow compensator in the breathing circuit automatically prevents re-breathing of exhaled gas. Because the mask has a sealing cushion, contamination of the clinical room where the apparatus is being used also is avoided. In an alternatively preferred embodiment, the fresh gas supply tube and the exhalation limb of the breathing circuit are replaced by a single length of co-axial flexible tubing connected between the face mask and a branched coupling. The branched coupling, in turn, includes a first branch for connection to the fresh gas supply nozzle of the “dental” set-up and a second branch for connection to a flexible flow-through reservoir bag used to store waste or exhaled gas. A one-way valve is disposed between the second branch output nozzle and the input of the flexible bag. The output of the flexible flow-through bag is connected to the vacuum module of the “dental” set-up. The second branch of the coupling, the one-way valve, and the flexible flow-through reservoir bag define the exhalation limb of the breathing circuit.
