Medical connector with lift tabs

1. A connector for coupling a medical fluid supply tube to the head of a catheter device having a circular hub with a circumferential recess defined in a side surface of the circular hub, the connector comprising:

a cap having a top surface, a bottom surface, a central region, and a circumferential region; the cap defining at least two pairs of slots, each slot defined completely through the cap and extending through a circumferential edge that defines the circumferential region of the radially towards the central region and each pair of slots dividing the cap into a plurality of lobes with a space between adjacent lobes, comprising:

at least two fixed lobes located on opposed portions of the cap, and

at least two resilient lobes, each resilient lobe being separated by a fixed lobe, each resilient lobe including:

a lift tab extending radially outward beyond the circumferential region of the cap,

an inwardly projecting catch that is configured to releasably engage a circumferential recess defined in a side surface of the circular hub, and

at least a resilient region;

wherein the connector is free to rotate completely about the circular hub, and wherein the connector decouples from the circular hub by actuating at least one lift tab to reversibly displace the resilient lobe and its respective catch radially by deforming the resilient region in order to disengage the catch from the circumferential recess without displacing the fixed lobes relative to the circular hub.

2. The connector of claim 1 , wherein the resilient lobes and the fixed lobes of the cap are formed from different materials.

3. The connector of claim 1 , wherein the resilient lobes and the fixed lobes of the cap are unitary.

4. The connection of claim 1 , wherein the connector is coupled to the hub by positioning the connector on the hub and pressing the top surface of the cap to move the bottom surface of the cap towards the hub until the catches engage the circumferential recess.

5. The connector of claim 1 , wherein each resilient lobe is reversibly deformed and spatially displaced when a force of between about 2 Newtons and about 14 Newtons is applied to its respective lift tab.

6. The connector of claim 1 , further comprising motion limiters to limit the pitch of the connector.

7. The connector of claim 1 , wherein each catch has a top surface configured to releasably engage the circumferential recess defined in the side surface of the circular hub and a bottom surface that is beveled.

8. The connector of claim 1 , further comprising a conduit defining a fluid pathway through the connector, the conduit configured to supply a liquid to a lumen defined by a catheter of the enteral feeding device.

9. The connector as in claim 1 , wherein the catheter device is an enteral feeding device having a circular hub, the connector configured to connect the medical supply tube to the circular hub of the enteral feeding device.

10. The connector as in claim 9 , further comprising an enteral feeding extension tube in fluid communication with the connector.

11. A connector for coupling a medical fluid supply tube to the head of a catheter device having a circular hub with circumferential recess defined in a catheter device having a circular hub, the connector comprising:

a cap having a top surface, a bottom surface, a central region, and a circumferential region; the cap defining at least two pairs of slots, each slot extending from the circumferential region of the cap toward the central region and each pair of slots dividing the cap into a plurality of lobes comprising:

at least two fixed lobes located on opposed portions of the cap, and

at least two resilient lobes, each resilient lobe being separated by a fixed lobe, each resilient lobe including:

an outwardly projecting lift tab,

an inwardly projecting catch that is configured to releasably engage a circumferential recess defined in a side surface of the circular hub, and

at least a resilient region;

wherein the connector is free to rotate completely about the circular hub, and wherein the connector decouples from the circular hub by lifting at least one lift tab to reversibly displace the resilient lobe and its respective catch radially by deforming the resilient region in order to disengage from the circumferential recess; and

wherein each resilient lobe has a port located above the catch to permit visual inspection of engagement between the catch and the circumferential recess defined in the side surface of the circular hub.
