Closed suction catheter adapter with flush arrangement
First Claim
1. A respiratory apparatus for connecting a respiratory device to an artificial airway of a patient, the apparatus comprising:
- an adapter assembly including;
a ventilator port for connection to a ventilating device,a respiratory port for connection to the artificial airway,an access port including a conduit defining a passageway extending from an open, insertion end,a flush port projecting from the conduit and fluidly open to the passageway at a flush port outlet; and
a catheter assembly including;
a fitting including a hub and a tube extending from the hub to a trailing end, wherein the tube defines;
an exterior surface,an interior surface forming a lumen,a circumferential groove in the exterior surface adjacent the trailing end,a plurality of apertures fluidly open to the lumen and the exterior surface in a region of the circumferential groove,a catheter assembled to the fitting, the catheter defining a distal end;
wherein the tube is sized to be slidably received within the passageway such that upon final assembly, a fluid pathway is formed between the flush port and the distal end of the catheter via the flush port outlet, the circumferential groove, the plurality of apertures, and the lumen.

Abstract
A respiratory apparatus including an adapter assembly and a catheter assembly. The adapter assembly includes ventilator, respiratory, access, and flush ports. The access port includes a conduit defining a passageway. The flush port projects from the conduit and is fluidly open to the passageway at an outlet. The catheter assembly includes a catheter assembled to a fitting. The fitting includes a hub and a tube, with the tube defining an exterior surface, an interior surface forming a lumen, a circumferential groove in the exterior surface, and a plurality of apertures fluidly open to the lumen and the circumferential groove. The tube is sized to be slidably received within the passageway such that upon final assembly, a fluid pathway is formed between the flush port and a distal end of the catheter via the flush port outlet, the circumferential groove, the plurality of apertures, and the lumen.

16. A method of connecting a respiratory device to an artificial airway of a patient, the method comprising:
-
fluidly connecting a ventilator port of an adapter assembly to a ventilating device; fluidly connecting a respiratory port of the adapter assembly to the artificial airway; establishing a fluid connection between the ventilating device and the artificial airway via the adapter assembly; connecting a catheter assembly to an access port of the adapter assembly, wherein the catheter assembly includes; a fitting including a hub and a tube extending from the hub to a trailing end, the tube forming an interior lumen, a circumferential groove, a plurality of apertures fluidly open to the lumen and the circumferential groove, a catheter assembled to the fitting an defining a distal end; wherein upon final connection, the circumferential groove is fluidly aligned with an outlet of a flush port provided with the adapter assembly, and a fluid pathway is established between the flush port and the lumen via the circumferential groove and the apertures. - View Dependent Claims (17, 18, 19, 20, 21)
