Abstract
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 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.
Claims20
A connecting adapter configured to releasably connect a patient interface connector to a gas delivery tube connector by insertion into each of the patient interface connector and the gas delivery tube connector, the connecting adapter comprising:
- a body extending between a terminal aperture configured to be positioned proximate the patient interface connector and a source aperture configured to be positioned proximate the gas delivery tube connector;
- the body comprising a cylindrical portion positioned between the terminal aperture and the source aperture, the cylindrical portion being configured to be received within the patient interface connector;
- two fingers extending away from the source aperture, the two fingers being spaced apart and narrowing along their length away from the source aperture, the two fingers comprising locking recesses that are formed at least on outer surfaces of each of the two fingers, the locking recesses being configured to lock with portions of the gas delivery tube connector, the two fingers also being configured to interact with recesses of the gas delivery tube connector to align the connecting adapter and the gas delivery tube connector.
A respiratory system connecting adapter configured to releasably attach a first conduit connector to a second conduit connector, the respiratory system connecting adaptor comprising a conduit body, the conduit body comprising a cylindrical portion, the cylindrical portion defining a source aperture at a first end and a terminal aperture at a second end, two fingers extending axially away from the source aperture, the two fingers each comprising a locking recess formed on an outer surface, the two fingers each having an arcuate distal end and a wider end adjacent to the source aperture, and a valley being defined between the two fingers.
