Pneumatic connector apparatus and method

A respiratory therapy device comprising

• a respiratory control unit configured to provide at least one respiratory therapy for a user,
• a respiratory circuit coupled to the respiratory control unit to deliver the respiratory therapy to the user, the respiratory circuit including an adaptor, and
• a multi-port connector interconnecting the respiratory circuit to the respiratory control unit, the multi-port connector comprising,
• a connector base coupled to the respiratory control unit,
• a receiver disk coupled to the connector base, and
• a plurality of barbed conduits coupled to the receiver disk and adapted to be coupled to the adaptor, each of the barbed conduits including a head section adapted to couple with the adaptor, a barbed section opposite the head section, and a retainer section interconnecting the head section and the barbed section and engaged with the receiver disk
• wherein the receiver disk is formed to include a plurality of apertures with a first diameter, and the retainer section of each of the plurality of barbed conduits has a second diameter greater than the first diameter so that each barbed conduit forms a friction-interference fit between the receiver disk and the retainer section,
• wherein the barbed section has an outermost diameter less than the first diameter and the second diameter to allow insertion of each of the plurality of barbed conduits through a respective aperture included in the plurality of apertures, and the head section includes a shoulder having a third diameter greater than the first diameter and the second diameter so that the shoulder engages an outer surface of the receiver disk when each of the plurality of barbed conduits are inserted through each respective aperture in a first direction, and
• wherein the receiver disk is formed to include a guide slot with a first rectangular portion that extends along a first axis and a second portion opening into the first portion that extends along a second axis that is perpendicular to the first axis, and
• wherein the adaptor includes a guide post with a shape that matches the guide slot and that is inserted into the first rectangular portion and the second portion of the guide slot when the adaptor is coupled with the multi-port connector.

A respiratory therapy device comprising

• a respiratory circuit coupled to the respiratory control unit to deliver the respiratory therapy to the user, the respiratory circuit including an adaptor, and
• a multi-port connector interconnecting the respiratory circuit to the respiratory control unit, the multi-port connector comprising,
• a connector base coupled to the respiratory control unit,
• a receiver disk coupled to the connector base and is formed to include a first detent notch and a second detent notch spaced apart circumferentially from the first detent notch, and
• a plurality of barbed conduits coupled to the receiver disk and adapted to be coupled to the adaptor, each of the barbed conduits including a head section adapted to couple with the adaptor, a barbed section opposite the head section, and a retainer section interconnecting the head section and the barbed section and engaged with the receiver disk
• wherein the receiver disk is formed to include a plurality of apertures with a first diameter, and the retainer section of each of the plurality of barbed conduits has a second diameter greater than the first diameter so that each barbed conduit forms a friction-interference fit between the receiver disk and the retainer section,
• wherein the barbed section has an outermost diameter less than the first diameter and the second diameter to allow insertion of each of the plurality of barbed conduits through a respective aperture included in the plurality of apertures, and the head section includes a shoulder having a third diameter greater than the first diameter and the second diameter so that the shoulder engages an outer surface of the receiver disk when each of the plurality of barbed conduits are inserted through each respective aperture in a first direction, and
• wherein the receiver disk is coupled to the connector base for pivotable movement relative to the connector base about an axis between an unlocked orientation and a locked orientation and the adaptor is configured to be coupled to the plurality of barbed conduits when the receiver disk is in the unlocked orientation, and
• wherein the first detent notch and the second detent notch are formed in a back side of the receiver disk and extend inwardly from an outer edge of the receiver disk toward the axis, and wherein the connector base includes a detent tab that engages the first detent notch when the receiver disk is in the unlocked orientation and engages the second detent notch when the receiver disk is in the locked orientation.
