ABSTRACT:
A spike exchanger to move a spike from one peritoneal dialysis bag to another. A pair of peritoneal dialysis bags are positioned by a base having clamps for releasably closing the tubular ports of each bag. A patient connectable tube with a spike shaped end is removably mounted to a device slidably mounted on the base and guided by means of a slot and roller combination to the tubular port of either bag. Various embodiments of the slot roller mechanism guide the spike shaped end to the tubular ports. A hook shaped tool pivotally mounted upon the base is engageable to unlock a sterile clamp mounted to the spike and port of one bag. Spaced apart and integrally connected arms moveably mounted to the base receive a sterile clamp and are positionable to lockingly mount a sterile clamp to the spike and port of the other bag. A further hook shaped arm pivotally mounted to the base is moveable against a bag port to hold the port immoveably straight as it is engaged by the spike.
