ABSTRACT:
A scavenging valve for anesthesia gas release in pediatric anesthesia apparatus is of generally conical configuration and has an axial bore extending therethrough from an open base to an open apex with a plurality of longitudinally extending fins around the bore in the valve. The scavenging valve has a plurality of external fin-like projections at its base. Each of the fin-like projections has a hole formed therethrough for facilitating releasable affixing of the scavenging valve to an operating table to prevent shifting of the valve. A control valve comprises a pair of nipples each of generally conical configuration in base to base relation with an axial bore extending therethrough from one open apex end to the other. The control valve has a radially extending hole formed therethrough at the juncture of the bases of the nipples. The bore tapers down to each of the apices from the bases. The control valve couples an anesthesia bag to the scavenging valve and has a gas flow control and shutoff plate pivotally mounted in the bore thereof in the area of the bases of the control valve. A manually operable control member is provided outside the control valve. A pin extends through the hole through the control valve and couples the control member to the valve plate in a manner whereby the valve plate rotates in correspondence with rotation of the control member.
