Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
192 words
A connector, for use with respiratory 65 apparatus, the connecto ' r comprising a housing having: a first opening. for providing communication between the interior of an endotracheal tube and the interior of the housing; a second opening for receiving an aspiration line; and a third opening for connecting the housing to a supply line for supplying respiratory gas to the connector; wherein the second opening comprises a passageway, extending between the exterior and the interior of the housing, having an inlet in a region of the passageway adjacent the exterior of the housing, the inlet being covered by a first sealing member, connected to a region of the housing and rotatable about that region to open the inlet, and an outlet in a region of the passageway adjacent the interior of the housing, the outlet being cov ered by a second sealing member, held in a position in which the outlet is closed, under the action of resilient means, and being displaceable against the action of said resilient means to open the outlet, thereby allowing the aspiration line to pass through the second opening when the inlet and outlet are open.
Claim 2
Dependent Claim
192 words
A connector, for use with respiratory 65 apparatus, the connecto ' r comprising a housing having: a first opening. for providing communication between the interior of an endotracheal tube and the interior of the housing; a second opening for receiving an aspiration line; and a third opening for connecting the housing to a supply line for supplying respiratory gas to the connector; wherein the second opening comprises a passageway, extending between the exterior and the interior of the housing, having an inlet in a region of the passageway adjacent the exterior of the housing, the inlet being covered by a first sealing member, connected to a region of the housing and rotatable about that region to open the inlet, and an outlet in a region of the passageway adjacent the interior of the housing, the outlet being cov ered by a second sealing member, held in a position in which the outlet is closed, under the action of resilient means, and being displaceable against the action of said resilient means to open the outlet, thereby allowing the aspiration line to pass through the second opening when the inlet and outlet are open.
Claim 3
Dependent Claim
36 words
