Abstract
A subcutaneous catheter set is disclosed in which a multilumen catheter tube has a tissue cuff connected about its outer circumference. A lock adapter has a plurality of conduits in communication with the lumens of the multilumen catheter tube. A complementary lock adapter is connected to either another multilumen catheter tube, a plurality of single lumen lines, a plurality of injection tubes or may be plugged to act as a seal. The two lock adapters can be locked together so that the subcutaneous multilumen catheter may be connected directly to any of the items attached on the complementary lock adapter.

6. An injection adapter for a multilumen catheter set comprising:
-
a first lock adapter including a plurality of conduits providing communication between a plurality of openings in a front face of said first lock adapter and a plurality of ports in a rear face of said first lock adapter; a lock ring for achieving locking engagement between said first lock adapter and a second lock adapter having a plurality of conduits so that the conduits of said second lock adapter are in communication through the front face of said first lock adapter with the conduits of said first lock adapter; and at least one rigid injection tube each having one end connected to one of said ports and an other end covered with a plug penetrable by a needle and resealable so that when a needle inserted through said plug into said tube is withdrawn said plug reseals said other end of said injection tube. - View Dependent Claims (7, 8, 9)

10. A sealing cap for a multilumen catheter set comprising:
-
a first lock adapter including a plurality of protrusions in a front face, at least one of said protrusions being solid; and a lock ring for achieving locking engagement between said first lock adapter and a second lock adapter having a plurality of conduits in communication with the lumens of a multilumen catheter, said first lock adapter engaging said second lock adapter so that when locked each of said at least one solid protrusions matingly engages one of said conduits to close off said one of said conduits. - View Dependent Claims (11, 12, 13, 14)
