Abstract: A bougie for insertion in a patient, the bougie including: (i) a main shaft having proximal and distal ends and a bore extending axially therein; (ii) a movable tip having proximal and distal ends, the proximal end of the movable tip being connected to the distal end of the main shaft; (iii) a control member having proximal and distal ends, the control member being mounted for sliding movement in the bore of the main shaft; and (iv) the distal end of the control member being coupled to the distal end of the movable tip, the arrangement being such that an operator can slide the control member relative to the main shaft so as to cause displacement of the tip relative to the axial direction of the main shaft.

Abstract: A portable suction device comprising: a gas inlet for receiving pressurized gas from an enclosed source; a gas flow path that extends from the gas inlet to an exhaust; a suction generator that has a suction inlet, the gas flow path extending through the suction generator, such that gas flow through the flow path generates a low pressure at the suction inlet; a collection container with a collection inlet and an outlet that is coupled to the suction inlet; a suction tube that has proximal and distal ends, the proximal end being connected to the collection inlet of the collection container; a valve for controlling gas flow through the flow path, the valve having a stem that is configured to pierce the source with movement of the valve from a closed position.

Abstract: A portable vacuum device including: a source of liquefied gas; a gas operated vacuum generator having a vacuum inlet; a valve for controlling flow of gas from the source to the vacuum generator; a suction tube having proximal and distal ends; a collection container having an outlet coupled to the vacuum inlet of the vacuum generator and an inlet coupled to the proximal end of the suction tube, the arrangement being such that when said valve is opened the vacuum generator creates a vacuum in the container and at the distal end of the suction tube.
