Abstract

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.

First claim

What is claimed is:

1. A connector assembly for a gas delivery conduit for providing gases to a patient, the connector assembly comprising:
a first conduit connector, and
a connecting adapter configured to releasably connect the first conduit connector to a second conduit connector, the connecting adapter comprising:
a first adapter conduit body; and
one or more locking fingers configured to releasably attach to the first conduit connector, the one or more locking fingers protruding longitudinally from the first adapter conduit body; and

the first conduit connector comprising:
a first connector conduit body;
one or more locking tabs configured to releasably engage with the one or more locking fingers when the connecting adapter is received into a terminal aperture of the first conduit connector, the one or more locking tabs protruding radially inward from an interior surface of the first connector conduit body; and
an alignment tab protruding radially inward from the interior surface of the first connector conduit body, the alignment tab configured to self-align the one or more locking fingers with the one or more locking tabs when the connecting adapter is received into the terminal aperture.

2. The connector assembly of claim 1 , wherein the first conduit connector further comprises a sensor port configured to receive a sensor probe, the sensor port formed substantially perpendicularly adjacent to the terminal aperture.

3. The connector assembly of claim 2 , wherein the sensor port provides a sensor aperture into the first conduit connector, the sensor aperture adjacent to an insertion aperture formed by the one or more locking fingers when the connecting adapter is received into the terminal aperture, the sensor aperture configured to allow the sensor probe to extend into the insertion aperture.

4. The connector assembly of claim 3 , wherein the one or more locking fingers extend past the sensor aperture when the connecting adapter is received into the terminal aperture.

5. The connector assembly of claim 1 , wherein the first conduit connector further comprises a receptacle configured to receive a sensor probe, the receptacle configured to position the sensor probe to extend into an insertion aperture formed by the one or more locking fingers when the connecting adapter is received into the terminal aperture.

6. The connector assembly of claim 1 , wherein engagement of the one or more locking tabs with the one or more locking fingers generates an audible sound.

7. The connector assembly of claim 1 , wherein the connecting adapter is configured to provide a quick connect mechanism between the first conduit connector and the second conduit connector.

8. A connector for a gas delivery conduit for providing gases to a patient, the connector comprising:
a conduit body comprising a terminal aperture, the terminal aperture configured to receive a connecting adapter into the conduit body;
a sensor port formed substantially perpendicularly on the conduit body, the sensor port configured to receive a sensor probe and provide the sensor probe with access to airflow within the conduit body; and
a locking tab protruding inward from an interior surface of the conduit body, the locking tab configured to releasably engage with a locking finger of the connecting adapter when the connecting adapter is received into the terminal aperture;
wherein the sensor port is substantially adjacent to the terminal aperture.

9. The connector of claim 8 , further comprising an alignment tab protruding inward from the interior surface, the alignment tab configured to self-align the locking finger with the locking tab when the connecting adapter is received into the terminal aperture.

10. The connector of claim 9 , wherein the alignment tab comprises a single continuous ridge formed circumferentially on the interior surface, the single continuous ridge alternating between a first distance from the terminal aperture and a second distance from the terminal aperture, the first distance being shorter than the second distance.

11. A connector for a gas delivery conduit for providing gases to a patient, the connector comprising:
a conduit body;
a locking tab configured to releasably engage with a locking finger of a connecting adapter when the connecting adapter is received into a terminal aperture of the connector, the locking tab protruding radially inward from an interior surface of the conduit body; and
an alignment tab configured to self-align the locking finger with the locking tab when the connecting adapter is received into the terminal aperture, the alignment tab protruding radially inward from the interior surface.

12. The connector of claim 11 , wherein the alignment tab comprises a single continuous ridge formed circumferentially on the interior surface, the single continuous ridge alternating between a first distance from the terminal aperture and a second distance from the terminal aperture, the first distance being shorter than the second distance.

13. The connector of claim 11 , further comprising a sensor port configured to receive a sensor probe, the sensor port formed adjacent to the terminal aperture.

14. The connector of claim 13 , wherein the sensor port is formed substantially perpendicularly to the conduit body.

15. The connector of claim 13 , wherein the sensor port is configured to allow the sensor probe to extend into an insertion aperture formed by the connecting adapter when the connecting adapter is received into the terminal aperture.
