HEMODIALYSIS SYSTEM HAVING CLAMPING MECHANISM FOR PERISTALTIC PUMPING

摘要

A hemodialysis system including (i) an instrument; (ii) first and second peristaltic dialysate pumps operated by the instrument; (iii) a cassette including a rigid structure and first and second dialysate pumping tubes carried by the rigid structure; and (iv) a mechanism configured to initially allow the cassette to be accepted by the dialysis instrument after which the mechanism engages the first and second dialysate pumping tubes for operation with the first and second peristaltic dialysate pumps.
