First Claim
Patent Images
1. A spike exchanger for continous ambulatory peritoneal dialysis comprising:
- a base having mounting means to releasably hold a first bag with a first port and a second bag with a second port;
clamp means on said base and engageable with said first port and said second port to releasably limit fluid flow therethrough;
spike holding and moving means movably mounted to said base and operable to releasably hold a spike in fluid communication with said first port and move said spike away from said first port to said second port; and
,guide means on said base and associated with said spike holding and moving means to guide and align said spike with said second port as said spike is moved thereto.

Abstract
A spike exchanger to move a spike from one peritoneal dialysis bag to another. A pair of peritoneal dialysis bags are mounted to 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 bar slidably mounted on the base and guided by means of a slot and roller combination to the tubular port of either bag. Three embodiments of the slot roller mechanism guide the spike shaped end to the tubular ports.

12. A medical apparatus comprising:
-
a first bag for holding liquid and including a first tubular port; a second bag for holding liquid and including a second tubular port; a frame with mounting means to releasably hold said first bag and said second bag; clamp means mounted to said frame and releasably engaged with said first tubular port and said second tubular port to control fluid flow therethrough; a patient connectable tube with a spike shaped male end in fluid communication with and fittable into said first tubular port when aligned therewith and into said second tubular port when aligned therewith; operator means movably mounted to said base and releasably holding said spike shaped male end, said operator means movable from a first position whereat said male end is in said first port to said second position whereat said male end is in said second port; and
,alignment means on said base and engaged with said operator means to align said male end with said second port when said operator means is moved to said second position. - View Dependent Claims (13, 14)
