# 6. Device Description
The Disposable Endobronchial Blocker Tube is used to isolate the left or right lung of a patient for surgery, one lung ventilation or one lung anesthesia. It is composed of blocker catheter, cuff, three-way connector, tube connector, one-way valve (with a pilot balloon) and multifunctional adaptor.
The blocker catheter has a flexible angled tip which can be easily placed into desired bronchus. It also contains a polyurethane cuff at its distal tip to create an effective seal within the inner bronchial wall and minimize potential trauma to the bronchus. The proximal end of the blocker catheter is bonded with a one-way valve and a pilot balloon assembly. This pilot balloon assembly facilitates inflation of the distal balloon and maintains inflation until it is released. The distance markings on the blocker catheter indicate how far the blocker has been advanced.
The multi-functional adaptor can be used by connecting a blocker tube to various endotracheal tubes and anesthetic circuits.
The Disposable Endobronchial Blocker Tube is available in three models: 5Fr, 7Fr and 9Fr. The device is composed of biologically safe materials. It is supplied sterile and intended for single use only.
