OP-Flex™ handles and sets are designed for intra operative removal of blood and fluids during open surgery. Must be attached to a jar/canister via a tube before connecting to a vacuum source of max. 400 mmHg. The flattened Yankauer is designed with a narrower tip (“duckbill”), used when space is limited and to increase accuracy of suctioning. The product is intended for single use only.
