SODIUM AND BUFFER SOURCE CARTRIDGES FOR USE IN A MODULAR CONTROLLED COMPLIANT FLOW PATH
First Claim
1. A system for generating a physiologically compatible fluid, comprising:
- a conditioning flow path having at least a salination valve or salination pump, and at least one container having at least one solute in excess of the solubility of that solute wherein at least one of the solutes is a buffer source or sodium chloride;
said conditioning flow path in fluid communication with a controlled compliant flow path wherein the conditioning flow path can selectively meter fluid into and out of the controlled compliant flow path.

Abstract
Systems and methods for using a sodium chloride source and a buffer source such as sodium bicarbonate in a controlled compliant flow path to generate from water a physiologically compatible fluid having a suitable level of a sodium ion and/or a buffer for use in hemodialysis, hemodiafiltration and hemofiltration. The system has a conditioning flow path that has at least a salination valve or salination pump, and at least one container has at least one solute in excess of the solubility of that solute. At least one of the solutes is a buffer source or sodium chloride. The conditioning flow path is in fluid communication with a controlled compliant flow path. The conditioning flow path can selectively meter fluid into and out of the controlled compliant flow path.

50. A method for generating a physiologically compatible fluid, comprising the steps of:
-
providing water to a system having a conditioning flow path in fluid communication with a controlled compliant flow path wherein the controlled compliant flow path is in fluid communication with an extracorporeal flow path across a semi-permeable membrane; configuring the system to bypass the extracorporeal flow path, the system having a bypass conduit flow path for conveying fluid through a first segment of the controlled compliant flow path without contacting the semipermeable membrane; conveying the water through the salination flow path; reconstituting an electrolyte source to generate a physiologically compatible fluid, and conveying the fluid through the first segment of the controlled compliant flow path. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57, 58)
