20150238679 | HEMODIALYSIS SYSTEM WITH CASSETTE-BASED BLOOD AND DIALYSATE PUMPING - A hemodialysis system includes: (i) a dialyzer; (ii) a dialysate source; a dialysate pump; (iii) a dialysate cassette operatively connected to the dialysate pump such that the dialysate pump can pump dialysate through the dialysate cassette when the dialysate cassette is in fluid communication with the dialysate source, the dialysate cassette in fluid communication with the dialyzer; (iv) a blood pump; and (v) a blood cassette separate from the dialysate cassette, the blood cassette operatively connected to the blood pump such that the blood pump can pump blood through the blood cassette, the blood cassette including a housing, the housing including a from-patient tube connector, a to-patient tube connector, a saline/priming tube connnector, a to-dialyzer tube connector, a from-dialyzer tube connector, and an internal air separation chamber. | 08-27-2015 |
20150258263 | BALANCED FLOW DIALYSIS MACHINE - A system and method for balancing flows of renal replacement fluid is disclosed. The method uses pressure controls and pressure sensing devices to more precisely meter and balance the flow of fresh dialysate and spent dialysate. The balancing system may use one or two balancing devices, such as a balance tube, a tortuous path, or a balance chamber. | 09-17-2015 |
