REVERSIBLE COMPONENT FOR MULTIPLE RESPIRATORY SUPPORT MODES

摘要

Systems and methods for coupling a respiratory support circuit (5, 5a) to a pressure generator (140) include multiple flow paths 13,17) for corresponding modes of operation. A first flow path (13) for a first mode of operation couples fluidly between the pressure generator, through a control port (12) and a circuit port (14), to an exhalation limb (20) of a dual-limb configuration of a respiratory support circuit. A second flow path (17) for a second mode of operates couples fluidly between the pressure generator, through a control port (16) and a circuit port (18), an exhalation valve (21) of a single-limb configuration of the respiratory support circuit.

主权项

1. An apparatus comprising:
a body configured to be coupled operatively with a pressure generator and tubing to provide a respiratory support circuit to a subject, wherein the body is configured to effectuate switching between a first mode of operation and a second mode of operation, the body comprising:
a first control port configured to couple fluidly with the pressure generator;a first circuit port configured to couple fluidly with an exhalation limb of the respiratory support circuit;a first flow path formed between the first control port and the first circuit port, wherein the first flow path is used in the first mode of operation;a second control port configured to couple fluidly with the pressure generator;a second circuit port configured to couple fluidly with an exhalation valve of the respiratory support circuit; anda second flow path formed between the second control port and the second circuit port, wherein the second flow path is used in the second mode of operation.
