Abstract: A multiple lumen vascular access port including a base, first and second lumens in the base, first and second catheters in communication with the first and second lumens, respectively, a boss in contiguous relationship to the first lumen to permit its identification by feel, metal tubes in the catheters proximate the lumens to prevent leakable puncture of the catheters in the event of penetration of the catheters by a needle, and a tube leading to the second lumen being recessed within a metal portion of the first lumen to prevent access thereto by a needle which might puncture it. The vascular access port can contain more than two lumens.

Abstract: An integral tube-loading assembly for a peristaltic pump having an eccentric motor shaft mounting a rotor within a housing wall including a trunnion mounted on the rotor shaft, a first link pivotally mounted on the trunnion, a second link pivotally mounted on the first link, a tube-loading pin member carried in a slot in the second link, the trunnion and first and second links being positioned on the rotor so that the pin member is always directed at the maximum spacing between the rotor and the housing wall, and a threaded bore in the rotor for receiving the pin member in a stowed condition.
