VENTURI GEOMETRY DESIGN FOR FLOW-GENERATOR PATIENT CIRCUIT |
摘要 |
Provided is a universal interface adapted for providing continuous positive airway pressure to a patient when the interface is used with a standard ventilator. The interface is configured to operate at a supply pressure no greater than about 120 centimeters of H2O in order to deliver pressure to the patient of up to about 15 cm of H2O at a flow rate of up to about 12 liters/minute. The universal interface may comprise an interface body having a space pair of breathing passageways intersecting a corresponding of supply passageways. Each one of the breathing passageways is comprised of a patient passageway and an exhalation passageway. Each one of the supply passageways includes a jet venturi having a taper portion. Each one of the exhalation passageways includes a taper portion which tapers outwardly along a direction from the patient passageway toward the exhalation passageway. |
