Abstract
Device for ventilation with a double lumen endotracheal tube featuring a connecting piece at the end distal to the patient into which the two lumina of the endotracheal tube are extended, separated within the connecting piece by an axial partition wall, a connector with two nozzles leading to a joint connecting section and separated from each other by another partition wall, the connector being attachable to the connecting piece in a way that brings the partition wall and the other partition wall into a sealing contact, a ventilator and at least one tube connected to a nozzle of the connector at one end and to the ventilator at the other.
Claims36
Device for ventilation comprising
- a double lumen endotracheal tube with an inspiratory lumen and an expiratory lumen and with a connecting piece at the end distal to the patient, both lumina of the endotracheal tube extending into the connecting piece and separated within it by an axial partition wall,
- an independent connector with separate inspiratory and expiratory tube nozzles extending from a first end of the connector and that intersect within the connector to form inspiratory and expiratory chambers that remain separated from each other by a connector partition wall that extends from within the connector to an opening at the opposing end of the connector, said opening being connectable to the connecting piece of the double lumen endotracheal tube such that the partition wall of the endotracheal tube and the connector partition wall join to form a seal, and
- a ventilator that is suitably connected to one or both of the inspiratory and expiratory tube nozzles at the first end of the connector,
- wherein the connector features a shutter bridging the two sides of the connector partition wall, or in which the connecting piece of the endotracheal tube features a shutter bridging the two sides of the axial partition wall.
A connector device for safely connecting an endotracheal tube to a further device, the connector comprising separate inspiratory and expiratory tube nozzles extending from a first end of the connector and that intersect within the connector to form inspiratory and expiratory chambers that remain separated from each other by a connector partition wall that extends from within the connector to an opening at the opposing end of the connector, said opening being connectable to an endotracheal tube such that, when the endotracheal tube is a double lumen endotracheal tube with a partition wall delineating the two lumina, such partition wall joins to the connector partition wall to form a seal, wherein the connector partition wall further comprises a shutter with a valve seat bridging the two sides of the connector partition wall to allow or disallow a fluid connection between the inspiratory and expiratory chambers in the connector.
