MULTIPLE-TYPE CATHETER CONNECTION SYSTEM

摘要

A catheter connection system (32, 340, 394, 634) is defined by a rigid, tubular stem (34, 278, 288, 318, 342, 396, 496, 530, 574, 612) attached at a proximal end thereof to a medical device (016, 222, 246, 274, 312, 366, 636). The stem has one or more engagement barbs (49, 226, 254, 280, 290, 320, 358, 408, 466, 538, 586) encircling and radially, outwardly extending on an exterior surface of the stem. The engagement barbs can be configured having a variety of different sizes and positions. A locking barb (50, 228, 258, 294, 322, 360, 412, 472, 510, 541, 632) also encircles and radially, outwardly extends on the exterior surface of the stem. The locking barb is positioned between the medical device and the engagement barbs. A variety of fastening assemblies (57, 300, 304, 328, 414, 480, 492, 555, 600) are provided for inwardly compressing a portion of a body wall (53, 83, 376) of a selected catheter (54, 58, 244, 302, 330, 386, 416, 474, 518, 544, 594), chosen from two or more catheters, against the engagement barbs or locking barb on the stem when the stem is received in the lumen (54, 58, 244, 302, 330, 386, 416, 474, 518, 544, 594) of the selected catheter. The fastening assemblies create a mechanical joinder and liquid-tight seal between the selected catheter and the stem.
