Fuji Uniblocker

The Uniblocker bronchial blocker (Fuji Systems, Tokyo, Japan). This blocker is similar to the blocker of the Univent tube but it is designed to be placed through a standard single-lumen endotracheal tube. It has a fixed "hockey-stick" bend on the distal lumen that can be rotated to advance the blocker into the desired mainstem bronchus. The proximal end of the blocker is seen passing through the connector which is connected to the anesthetic circuit and has a port for a fiberoptic bronchoscope to aid positioning.
