Abstract

649,689. Respiratory appliances. COLLISON, W. E. Oct. 12, 1948, No. 26583. [Class 81(ii)] In order to prevent exhaled air mixing with incoming gas or vapour inhalation apparatus comprises a valve in the conduit to the patient's nose which is automatically opened or closed by the varying pressure in a tube leading to the mouth. In one embodiment a mask is formed with two chambers 2, 4, fitting over the nose and mouth respectively. Gas entering by a tube 1 passes to the nosepiece through a chamber 3 containing a ball valve 5 and' having an orifice 6 communicating with the mouthpiece. When the patient breathes in, the reduction in pressure in the mouthpiece causes the ball 5 to move to the left and block the orifice 6 and outlet tube 7, leaving the inlet tube unobstructed. When the patient breathes out the ball moves 'back to the position shown in full lines, so blocking the inlet tube and leaving a free passage for exhalation through the tube 7, which may be fitted with a non-return valve 9. In a modification a segmental flap valve is used in place of the ball type. (see Fig. 4 (not shown)).
