Claim Text:
1. An enteral feeding assembly with a lock assembly, comprising: a base configured to be disposed on a skin surface of a patient, the base having a distal surface configured to be positioned adjacent a skin surface, the base including an uppermost horizontal proximal surface having a key-hole opening with a predetermined non-circular shape formed therein and the base including a space formed below the proximal surface of the base, the space extending radially outward of the key-hole opening below the proximal surface of the base; a catheter carried by the base and having a lumen formed therethrough which is in communication with the proximal opening in the base, a portion of the catheter extending distally away from the distal surface of the base, at least a portion of the distal end of the catheter configured to be positioned in a body lumen; a feeding set connector disconnected and removed from said base, said connector axially insertable from above into the key-hole opening in the proximal surface of said base for use of said enteral feeding assembly to supply liquid nutrients to said body lumen, said connector including a flange key and a cuff extending from the flange key, and an opening formed through the feeding set connector, flange key and cuff; wherein the flange key has a predetermined non-circular circumferential shape that matches the predetermined non-circular shape of the key-hole opening in the proximal surface of the base so that the flange key moves vertically through the key-hole opening and into the space below the proximal surface of the base when the feeding set connector is at a rotational position such that the noncircular key flange is aligned with the non-circular key-hole opening, and the flange key is rotatable within the space between a locked position and an unlocked position relative to the base to connect said feeding set connector to said base, in the locked position, the flange key engaging against an underside of the proximal surface such that the feeding set connector cannot be pulled away from the base; wherein when the flange key is positioned within the base, the flange key can rotate through an angle of at least 90 degrees without becoming unlocked, and; when the flange key is positioned within the base, the cuff extends through the opening in the base and is in fluid communication with the lumen of the catheter so that liquid nutrients connected by tubing to said feeding set connector move through the feeding set connector and through the catheter lumen to said body lumen; and at least one detent defined in the base at a location relative to the unlocked position of the flange key such that, upon being rotated to the unlocked position, the flange key engages the detent thereby providing a tactile indication of increased resistance to rotation of the flange key prior to the flange key being rotated to the unlocked position.
