Abstract
A patient circuit of a ventilation system, such as a non-invasive open ventilation system, wherein the patient circuit comprises a nasal pillows style patient interface that incorporates at least one “Venturi effect” jet pump proximal to the patient. The patient circuit further comprises a pair of uniquely configured 3-way connectors which, in cooperation with several uniquely configured tri-lumen tubing segments, facilitate the cooperative engagement of the patient interface to a ventilator of the ventilation system.
Claims20
A patient interface for providing ventilation to an individual, the patient interface comprising:
- a manifold housing defining at least one gas pathway;
- at least one jet pump assembly coupled to the manifold housing and comprising:
- jet pump housing defining at least one entrainment port in fluid communication with ambient air;
- a jet nozzle cooperatively engaged to the jet pump housing, the jet nozzle defining a high-pressure jet nozzle outlet port and a low-pressure jet nozzle outlet port disposed in side-by-side relation to each other, at least the high-pressure jet nozzle outlet port being operative to facilitate air entrainment through the entrainment port and mixing of the entrained air with gas concurrently introduced into the gas pathway from the high and low-pressure jet nozzle outlet ports;
- at least one sensing tube extending into fluid communication with the gas pathway.
A respiratory assistance system, comprising:
- a ventilator;
- and
- a patient circuit comprising:
- a patient interface configured to facilitate air entrainment from ambient air and mixing of the entrained air with gas concurrently introduced thereinto from both high and low-pressure gas sources which are fluidly isolated from each other upstream of the patient interface;
- and
- a connector and tubing arrangement configured to facilitate flow from the ventilator as the high-pressure gas source to the patient interface alone or in combination with a source other than the ventilator serving as the low-pressure gas source to the patient interface, the connector and tubing arrangement further defining a sensing line fluidly isolated from the high and low-pressure gas sources and fluidly communicating with both the patient interface and the ventilator.
