Abstract
The invention features a component which is part of a breathing circuit for directing flow of air to and from a patient, the breathing circuit including an inspiratory tube defining an inspiratory lumen for flow of air to the patient and an expiratory tube defining an expiratory lumen for flow of air from the patient, the tubes being joined via a common wye piece to the component. The component includes each of inner and outer coaxial tubes, the inner tube defining an inner lumen in communication with the inspiratory lumen, the outer tube defining an outer lumen in communication with the expiratory lumen, wherein the outer tube is made from a collapsible and expandable tubing which is sufficiently flexible to assume a bent configuration and sufficiently stable to retain the bent configuration, and thus is virtually unlimited in its positionability with respect to the patient and the bulky portions of the breathing circuit.
