A portion 4() of the casing 1() is' extended upwardly and is bifurcated to pivotally receive a lever 41 mounted on a pivot ypin 42. This lever hasan overhanging rliglit angle flange 43 which normally holds the part-s in the position shown in the drawing. 'The l'ever il is v'provided with a 'cam zp'ortion 44 which engages the head 36 so as to opera'te the valve when the lever 41 is depressed.

munication with ,the

disinfectant 'been shown tion, so long as it serves to support the tissues and thereby permit the passage of the gas.

In operation the airway 64 is introduced into the mouth of the patient and urged past the tongue and into the throat so as to permit passa'gle of gas to the lungs. At the same time t e mask 28 is adjusted to 'the face so that the cushion 29 makes substantially a gas 'tigl'itcoiitact therewith. As the mask and its airway are carried by the casing 10, manipulation of both may be guided by the hand of operator grasping the casing 1() in position to operate the lever 41.

After the mask and airway have been placed in position, the lever 41 is depressed andthe cam 44 engaging the head 36' will -force the stem 33 downwardand consequently move the valve 3() downwardly against- 'the action of the spring 37. Downward "movementoffthe 'valve 30 will move the facei'l below the v,flange 13 and permit gas intllechaln ber 14, from the gas supply pipe to 'pass through the Vflange 13 into the chamber 15, which being tapped at 16 will com'nl'unicate the supply pressure through the pipe 17' to .passesthrough the end 6() intotheairway 64, a portion of the supply v'being directed "through the aperturesv61 :into the interior of vthe face mask to permit either nasal ormouth breathing. e n

When the `lever 41 is released the spring 3T will retract the valve sothat the surface 31 seats against the ian'ge'13. VThis movement will remove the lower surface of the valve from :the boss 51 so that vthe gas heling expelled from `the lungs of the patient'may pass into the air chamber 19 and he exhausted vthrough theaperturcs Q0, which are in comatmosphere. At the `same time xthe passage it''is also in communication with the air chamber '.19 so ,that the bleed passages 48 Aand the tap 16 will release the-pressure on the indicating device 'convnected'to the .pipe 17 to `permit it -to return to 4the 'zero position.. lt should befnoted that this arrangement permits normal fbi-cathfthrough either nose vor mouth 'to `take lplace at any time when the lever 4.1 is relleased, as the communication with `the atmosphere through the apertures Q0 is thereby established. f
