Abstract:
A valve (1), particularly suited for use with a patient ventilation system (18) to regulate respiration gas flow to and from the lungs (17) of a patient comprises a substantially parallel, typically co-axial, arrangement of inner (5) and outer (4) fluid flow passages for conducting gas through the valve to and from a common flow conduit (14) connected to the patient's lungs (17), each passage in a different direction. A cuff (7) is provide and is inflatable to control the flow of fluid through the valve (1). The cuff (7) is disposed so as to be able to form a fluid-tight seal against one or other of facing surfaces of the inner (5) and the outer (4) flow passages when inflated and block flow through the outer passage (4) in a timed relationship with the breathing cycle of the patient.
