ABSTRACT:
A housing pivotally supports a door which is interconnected with an arm carrying a hollow probe. A fillport module is slidable into operative position within the housing. The module supports a resilient fillport having an opening through which fluid passes. The opening has a tapered outer end for sealingly engaging a capillary tube. The probe is disposed within the opening and has an open outer end to receive fluid from a syringe. The probe is movable between an inner position where the outer end of the probe is within the opening when fluid is received from a capillary tube to an outer position where the outer end of the probe is disposed outwardly of the fillport when fluid is received from a syringe. A shoulder on the fillport sealingly engages the outer surface of the probe at all times, and a stop limits inward movement of the probe. A cleaner is carried by the door and is moved into sealing engagement with the fillport module so that a cleaning solution may be passed through the fillport and probe.
