Abstract
In accordance with the present invention, there is provided an adaptor or attachment which is suitable for integration into the patient circuit of a ventilation system, such as a non-invasive open ventilation system, is configured for attachment to any standard ventilation mask, and is outfitted with a jet pump which creates pressure and flow by facilitating the entrainment of ambient air. The adaptor comprises a base element and a nozzle element which are operatively coupled to each other. The base element further defines a throat and at least one entrainment port facilitating a path of fluid communication between the throat and ambient air. The nozzle element includes a jet nozzle, and a connector which is adapted to facilitate the fluid coupling of the nozzle element to a bi-lumen tube of the patient circuit. The connector includes both a delivery port and a sensing port. The jet nozzle and the delivery port collectively define a delivery line or lumen which fluidly communicates with the throat of the base element, and is placeable into fluid communication with the delivery lumen of the bi-lumen tube.
Core Innovation
The invention relates to an adaptor for fluid coupling in a ventilation system. The adaptor includes a base element defining a gas delivery conduit with a recess and an opening that extends between the gas delivery conduit and the recess along an axis, and an elongate pressure sensing line that extends in spaced relation to the axis and terminates at the recess.
The invention further relates to a connector that defines a gas delivery lumen and a pressure sensing lumen. The gas delivery lumen fluidly communicates with the gas delivery conduit of the base element, and the pressure sensing lumen is maintained in a constant state of fluid communication with an annular channel defined between the connector and the recess irrespective of an orientation of the connector relative to the base element.
Relative rotation of the connector and the base element does not compromise integrity of a pressure sensing conduit defined at least in part by the elongate pressure sensing line, the annular channel, and the pressure sensing lumen. The adaptor is coupled to a tube in which a gas delivery lumen and a pressure sensing lumen are fluidly isolated from one another.
Claims Coverage
The document provides two independent claims. Both independent claims share a core inventive concept centered on maintaining constant pressure-sensing fluid communication despite connector orientation and relative rotation.
Constant pressure-sensing communication despite connector orientation
A connector defines a pressure sensing lumen maintained in a constant state of fluid communication with an annular channel between the connector and the recess irrespective of an orientation of the connector relative to the base element, so relative rotation does not compromise integrity of a pressure sensing conduit.
Base element with aligned recess and elongate pressure sensing line
A base element defines a gas delivery conduit with a recess and an opening extending between the gas delivery conduit and the recess along an axis, and defines an elongate pressure sensing line that extends in spaced relation to the axis and terminates at the recess.
Connector lumens for gas delivery and pressure sensing
A connector defines a gas delivery lumen fluidly communicating with the gas delivery conduit of the base element and a pressure sensing lumen that communicates with the annular channel adjacent the recess.
Tube with isolated gas-delivery and pressure-sensing lumens coupled via the adaptor
A tube defines a gas delivery lumen and a pressure sensing lumen that is fluidly isolated from the gas delivery lumen, in combination with the adaptor, the connector adapted to facilitate fluid coupling while maintaining constant state fluid communication for the pressure sensing lumen despite connector orientation.
Across the independent claims, the inventive focus is the adaptor geometry and lumen and annular-channel arrangement that keeps a pressure sensing conduit intact and in constant fluid communication even when the connector is rotated relative to the base element, while supporting separate isolated gas delivery and pressure sensing lumens in the tube.
