Conduit connector for a patient breathing device
In an embodiment, a connector or connector assembly for attaching a nasal cannula with a gas delivery hose includes a sensor port for a sensor probe positioned near an end of a nasal cannula, which can allow the sensor probe to be placed closer to the patient's nostrils than previous connector parts allowed. The connector can be configured to advantageously allow the nasal cannula to rotate relative to the gas delivery hose, thereby allowing a patient or healthcare provider to untangle or otherwise straighten the hose or the cannula. The connector assembly can be configured to automatically align locking protrusions on a first component with locking recesses on a second component, where insertion of the second component within the first component causes the second component to rotate relative to the first component, thereby aligning the locking protrusions with associated locking recesses.
1. A connector assembly comprising:
a first connector portion configured to connect to a second connector portion, and
a connecting adapter, wherein the connecting adapter comprises a plurality of locking fingers,
the first connector portion comprising:
a locking groove formed around a circumference of an interior surface of the first connector portion;
a first opening configured to receive the connecting adapter; and
at least one second opening configured to receive at least one conduit.
2. The connector assembly of claim 1 , wherein the connecting adapter comprises a channel formed on an outside surface of a connecting adapter body, the channel configured to rotatably engage with ridges formed on the interior surface of the first connector portion.
3. The first connector portion of claim 1 , wherein an airtight seal is created between the first connector portion and the second connector portion when the second connector portion is connected to the first connector portion.
4. The first connector portion of claim 1 , comprising a lip around the first opening.
5. The first connector portion of claim 1 , comprising at least one ridge formed on the interior surface of the first connector portion.
6. The first connector portion of claim 5 , wherein the at least one ridge is formed longitudinally.
7. The first connector portion of claim 5 , wherein the at least one ridge is tapered in width or height.
8. The first connector portion of claim 1 , comprising one or more finger grooves formed on an outside surface of the first connector portion.
9. The first connector portion of claim 1 , wherein the at least one second opening comprises two openings, each of the two openings configured to receive one of the at least one conduit.
10. The first connector portion of claim 9 , wherein the at least one conduit connects at a terminal end to a prong for insertion into a patients nostril.
11. The first connector portion of claim 9 , wherein the at least one second opening is surrounded by an angled surface of the first connector portion, the angled surface configured to funnel airflow into the conduit.
12. The first connector portion of claim 1 , wherein the first connector portion is colored to indicate sizing information of the first connector portion.
13. The connector assembly of claim 1 , wherein the plurality of locking fingers comprise three locking fingers spaced around a body of the connecting adapter.
14. The connector assembly of claim 1 , wherein the connecting adapter is rotatable relative to the first connector portion when the first connector portion is engaged with the connecting adapter.
15. The connector assembly of claim 1 , wherein the connecting adapter comprises a collar configured to engage with the locking groove.
16. The connector assembly of claim 1 , wherein the plurality of locking fingers of the connecting adapter are configured to extend at least partially around a sensor probe within the second connector portion.
17. The connector assembly of claim 1 , wherein each of the plurality of locking fingers comprises one or more locking recesses configured to engage with locking tabs of the second connector portion.
18. The connector assembly of claim 17 , wherein the plurality of locking fingers are configured to interact with one or more alignment tabs on the second connector portion such that the plurality of locking recesses are aligned with the one or more locking tabs of the second connector portion when the connecting adapter is connected to the second connector portion.
