REAGENT SUPPLY FOR A HEMODIALYSIS SYSTEM
First Claim
1. A reagent supply arrangement for a hemodialysis system, including:
- an E-prong connector, having three parallel prongs with two outer prongs arranged in a common plane and a center prong arranged above the common plane;
a first supply line for a first reagent connected in fluid communication with one of the outer prongs;
a second supply line for a second reagent connected in fluid communication with the other of the outer prongs;
a liquid line connected in fluid communication with the center prong; and
a container for housing the first reagent having an inlet connected to the liquid line and an outlet connected to the first supply line for the first reagent.

Abstract
A reagent supply arrangement for a hemodialysis system may include an E-prong connector having three parallel prongs with two outer prongs arranged in a common plane and a center prong arranged above the common plane, a first supply line for a first reagent connected in fluid communication with one of the outer prongs, a second supply line for a second reagent connected in fluid communication with the other of the outer prongs, a liquid line connected in fluid communication with the center prong, and a container for housing the first reagent having an inlet connected to the liquid line and an outlet connected to the first supply line for the first reagent. The E-prong connector may help prevent the improper connection to the dialysis unit, e.g., because the prong arrangement ensures connection in only one way to the dialysis unit.

15. A method for operating a hemodialysis system, comprising:
-
providing a dialysis unit having an enclosure for containing suitable components for performing hemodialysis including a dialyzer, one or more pumps to circulate blood through the dialyzer, a source of dialysate, and one or more pumps to circulate the dialysate through the dialyzer, the enclosure including a housing supporting the components, the housing having a front panel at which blood circuit connections and dialysate fluidic connections are made; providing a reagent supply including an E-prong connector having three parallel prongs with two outer prongs arranged in a common plane and a center prong arranged above the common plane, a first supply line for a first reagent connected in fluid communication with one of the outer prongs, a second supply line for a second reagent connected in fluid communication with the other of the outer prongs, a liquid line connected in fluid communication with the center prong, and a container for housing the first reagent having an inlet connected to the liquid line and an outlet connected to the first supply line for the first reagent; and connecting the E-prong connector of the reagent supply to a connection point at the front panel of the dialysis unit, thereby allowing the dialysis unit to provide water to the liquid line of the reagent supply, and allowing the dialysis unit to receive the first and second reagents from the first and second supply lines. - View Dependent Claims (16, 17)
