Disposable suction collection canisters have snap-on lids which stay positively sealed, tubing hooks built right into the lids, and in-series hookups. They are adaptable to most portable floor suction units and all wall units in the OR, ER, ICU and CCU. Designed for single patient use, these canisters are also available with a lid which can be attached directly to a pipeline suction regulator having a DISS male vacuum inlet. They are convenient, practical and designed with the end user in mind.
