Abstract
A suction arrangement includes a suction source (1) with a single inlet (13) and a connector (5) of caltrop shape with four interconnected ribbed ports 50 to 53, one of which (50) is connected to the suction inlet. The other three ports (51 to 53) are connected with tubing interconnections (15, 23, 33, 46) which each have a valve or the like (25, 35, 48) for blocking flow as necessary. The tubing interconnections connect with respective suction appliances including a suction outlet (41) above the cuff (42) of a tracheal tube (40), a tracheal suction catheter (3) and an oral suctioning catheter (2).
Claims11
A fluid-flow connector characterized in that the connector includes four interconnected ports arranged for connection respectively to a source and to three fluid-flow appliances.
(canceled)
A fluid-flow arrangement according to claim 11, characterized in that one or more of the tubing interconnections includes an arrangement for blocking flow through the tubing interconnections.
A fluid-flow arrangement according to claim 11, characterized in that the source is a suction source and that at least one of the appliances is selected from a group consisting of a suction outlet above the cuff of a tracheal tube, a tracheal suction catheter and an oral suctioning catheter.
