Dialysis system
First Claim
1. A dialysate fluid circulation apparatus comprising:
- (a) a dialyzer;
(b) a first housing containing material capable of releasing sodium into dialysate fluid flowing through the first housing;
(c) a second housing containing material capable of binding sodium ions from dialysate fluid flowing through the second housing;
(d) hydraulic conduit sections configured to extend between the dialyzer, the first housing, and the second housing to connect the dialyzer with the first and second housings in a primary flow path for dialysate fluid to flow from the dialyzer to the first housing, from the first housing to the second housing, and from the second housing back to the dialyzer; and
(e) hydraulic conduit sections configured to define a bypass flow path, the bypass flow path providing a flow path for dialysate fluid to bypass the second housing by flowing from the first housing back to the dialyzer.

Abstract
A dialysate fluid circulation apparatus includes a dialyzer, a first housing and a second housing. The first housing contains material capable of releasing sodium into dialysate fluid flowing through the first housing. The second housing contains material capable of binding sodium ions from dialysate fluid flowing through the second housing. Hydraulic conduit sections are configured to extend between the dialyzer, the first housing, and the second housing to connect the dialyzer with the housings in a primary flow path for dialysate fluid to flow from the dialyzer to the first housing, from the first housing to the second housing, and from the second housing back to the dialyzer.

18. An apparatus for use with a dialysate fluid system comprising:
-
(a) a first housing containing material capable of releasing sodium into dialysate fluid flowing through the first housing; (b) a second housing containing material capable of binding sodium ions from dialysate fluid flowing through the second housing; (c) hydraulic conduit sections configured to define a primary flow path, the primary flow path providing a flow path into the first housing, a flow path between the first housing and the second housing, and a flow path exiting the second housing; (d) hydraulic conduit sections configured to define a bypass flow path, the bypass flow path providing a flow path connecting the primary flow path between the first housing and the second housing to the primary flow path exiting the second housing; and (e) a fluid flow regulator operative to control flows of dialysate fluid along the primary and bypass flow paths. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
