Enteral feeding extension set connector
First Claim
1. A connector for coupling a medical fluid supply tube to the head of a catheter device having a circular hub having a generally horizontal top surface that extends radially outward over a generally vertical side surface to define a circumferential recess in the side surface of the circular hub, the connector comprising:
- a resilient assembly including cantilevered springs, wherein each cantilevered spring has at least one arm, each arm having a first end, a central section, and a second end that is joined to a central support; and
a plurality of release buttons extending from the resilient assembly, each release button having a first portion including a finger contact zone and a second portion including a catch, the catch configured to releasably engage a circumferential recess defined in a side surface of the circular hub,wherein the connector is coupled to the circular hub having a generally horizontal top surface that extends radially outward over the generally vertical side surface to define a circumferential recess by positioning the connector on the hub and depressing the connector until the catches engage the circumferential recess such that the connector is free to rotate completely about the circular hub and the connector is decoupled from the hub by pressing the release buttons radially inward to reversibly displace the cantilevered springs thereby moving the respective catches radially outward to disengage them from the circumferential recess.

Abstract
A connector for coupling to a base of an indwelling device equipped with a circular hub having a radius, a top surface, a side surface, and a circumferential recess defined in the side surface. The connector has a resilient assembly including a plurality of release buttons extending from the resilient assembly and may include a conduit defining a fluid pathway through the connector. Each release button has a finger contact zone and a catch. The catch is configured to releasably engage the circumferential recess. The connector is coupled by positioning the connector on the circular hub and depressing the connector until the catches engage the circumferential recess such that the connector is configured to rotate completely about the circular hub. The connector is decoupled from the hub by pressing the release buttons to reversibly displace the respective catches radially to disengage from the circumferential recess.

9. An extension set connector for coupling a feeding extension set to a base of an enteral feeding tube device equipped with a circular hub having a radius, a generally horizontal to surface that extends radially outward over a generally vertical side surface to define a circumferential recess in the side surface, the connector comprising:
-
a resilient assembly including cantilevered springs, wherein each cantilevered spring has at least one arm, each arm having a first end, a central section, and a second end that is joined to a central support, and wherein each arm of the cantilevered springs has a length measured from its connection with the release button to its connection with the central support that is from about 0.75 to about 1.25 times the length of the radius of the circular hub; release buttons, each release button joined with a respective first end of an arm, each release button having a first portion comprising a finger contact zone on an outer surface, and a second portion comprising a catch on an inner surface, the catch configured to releasably engage the circumferential recess defined in the side surface of the circular hub; and a conduit defining a fluid pathway through the connector, the conduit configured to supply a feeding solution to a lumen of the enteral feeding tube device, wherein the connector is rotatably coupled to the circular hub having a generally horizontal top surface that extends radially outward over the generally vertical side surface to define a circumferential recess by positioning the connector on the hub and depressing the connector until the catches engage the circumferential recess defined in the side surface of the circular hub, and wherein the connector is decoupled from the hub by pressing the release buttons radially inward to reversibly displace the cantilevered springs thereby moving the respective catches radially outward to disengage from the circumferential recess. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
