Abstract
A fluid delivery connection includes a cuff to engage a port. A finger extends away from the cuff, and the finger is configured to interact with the port. A locking sleeve is movably disposed at least partially about the cuff and the finger. The locking sleeve is selectively movable between an unlocked configuration wherein the finger is movable and a locked configuration wherein the finger is secured to the port. A method of connection to a gas port includes moving a locking sleeve of a connector into an unlocked configuration. A finger of the connector is translated along the gas port and the locking sleeve is moved into a locked configuration.
Claims10
A fluid delivery connection, comprising:
- a cuff that is configured to engage a port and connect to a fluid delivery circuit, such as to create a fluid connection between the port and the fluid delivery circuit, an outermost surface of the cuff defining a first radius from a center of the cuff;
- a finger extending away from the cuff, the finger configured to interact with the port;
- and a locking sleeve movably disposed at least partially about the cuff and the finger, wherein the locking sleeve is selectively movable between an unlocked configuration wherein the finger is movable and a locked configuration wherein the finger is secured to the port, the locking sleeve consisting of a plurality of interconnected discontinuous ramps wherein each ramp comprises an inner surface having a continuously varying inner diameter throughout the ramp such that the inner surface is configured to progressively engage the finger as the locking sleeve is moved from the unlocked configuration to the locked configuration, the ramp extending radially and inwardly of the first radius.
A gas delivery system comprising:
- a gas port with an annular cut out;
- a breathing circuit configured to be connected to a patient to deliver medical gas to the patient;
- a cuff with a first end that removably engages the breathing circuit and a second end that removably engages the gas port, wherein the cuff creates a fluid connection between the gas port and the breathing circuit;
- a finger that selectively engages the gas port, the finger comprising a tab that selectively engages the annular cut out of the gas port;
- and a locking sleeve disposed about at least a portion of the cuff, the locking sleeve being selectively movable between an unlocked configuration wherein the finger is movable and a locked configuration wherein the finger is secured to the gas port and the tab is secured to the annular cut out of the gas port, the locking sleeve comprising a ramp extending radially inward from an inner surface of the locking sleeve, a first end of the ramp extending to a first distance, a second end of the ramp extending to a second distance greater than the first distance, the ramp having an increasing radial width from the first end to the second end such that the ramp is configured to progressively engage the finger as the locking sleeve is moved from the unlocked configuration to the locked configuration, the locking sleeve comprising a cutout extending through an interior surface and an exterior surface along a perimeter of the locking sleeve, the cutout configured to permit the finger to move radially outward when the locking sleeve is in the unlocked configuration.
