Abstract
A disposable trumpet valve for controlling irrigation and aspiration flows under manual operation comprises a conduit and a pair of spaced apart valve barrels of substantially greater cross-sectional size within which valve members are reciprocable under manual control. Large diameter sections of the valve barrels lead to transition wells merging in the same plane into the conduit and directing the flow path between a side port in the valve barrel and the bottom section of the barrel. Thus a large cross-sectional flow area is provided throughout in a device which may be manipulated with either hand. Integral seals on a slider piston function to block flow and prevent leakage, while at the same time substantial cost advantages are obtained.
