摘要： Needle covers are provided for medical needle assemblies having a base and a cannula. The needle cover includes hub and cap portions. The hub portion is adapted to be secured to the base. The cap portion is adapted to substantially enclose at least a distal end of the cannula when the hub portion is secured to the base. The cap portion includes at least one generally outwardly extending wing having an outer edge and an enlarged rib extending along only a portion of the outer edge of the wing and only in a direction substantially parallel to a central axis defined by the cap portion. The cap portion is separable from the hub portion upon application of a torsional force, with the rib of the wing being thicker than the portion of the wing radially inward of the outer edge to assist gripping during application of such force.

摘要： A self-loading peristaltic pumping apparatus includes a pump race for receiving a tubing loop, a pump rotor carrying a roller, and a drive mechanism for rotating the rotor within the pump race. The apparatus also includes a roller locating mechanism that moves the pump roller between a retracted position, free of contact with the received tubing loop, and an extended position, at least partially within the pump race for operative contact with the received tubing loop. The apparatus includes at least one tubing guide element carried by the rotor. The guide element extends from the rotor at least partially into the pump race. The guide element serves during rotation of the rotor with the roller in its retracted position, for contacting the received tubing loop to orient the tubing loop within the pump race.

摘要： An umbilicus is provided for use in an umbilicus-driven fluid processing system. The umbilicus has a pair of anchor portions, at least one fluid-transmitting lumen, and a drive shaft. The fluid-transmitting lumen and drive shaft extend between the anchor portions. The lumen and drive shaft may be comprised of different materials. If multiple lumen are provided, they may either be separate from each other and the drive shaft or defined in a single umbilicus body which also provides a lumen for receiving at least a portion of the drive shaft.

摘要： A blood processing centrifuge includes a disposable fluid processing assembly having a fluid processing chamber. Fluid is communicated to and from the fluid processing chamber through a flexible umbilicus. The fluid processing chamber spins while the centrifuge pulls the umbilicus around an axis of centrifugation. The centrifuge engages the umbilicus through a thrust bearing received in a gimbal assembly carried on a rotating wing plate. The gimbal assembly allows the umbilicus to pivot relative to the wing plate under the forces developed during centrifugation. The gimbal assembly includes a bearing retainer adapted to securely retain umbilicus thrust bearings of differing sizes a gimbal that loosely but securely retains the bearing retainer. Clearance between the gimbal and the bearing retainer enable the bearing retainer to accommodate thrust bearings of differing sizes without causing gimbal binding. The ability to accommodate umbilicus thrust bearing of differing sizes enables the thrust bearings to be manufactured to looser tolerances, thereby improving manufacturing ease and economy.

摘要： A support assembly for process control equipment includes a cabinet containing processing equipment. A vertical support pole is supported on said cabinet through a collar for extension and retraction. Process control equipment such as electronic control equipment and a video monitor is mounted on the upper end of the pole. At least one, and preferably two, constant force springs biased into a fully coiled position are attached at one end to the lower end of the pole. The opposite end of the springs are mounted for free rotation on a spool which is secured to the cabinet, whereby raising and lowering of the process control equipment is facilitated.
