Publication number: 20230381387Abstract: A water preparation apparatus for determining an amount of total chlorine in purified water is disclosed. The water preparation apparatus includes a chlorine sensing system, a water pretreatment filter, a reverse osmosis filter, and an electrodeionization (“EDI”) module. The chlorine sensing system is configured to determine an amount of total chlorine in the purified water by applying, at a first time, a source voltage to the purified water and removing, at a second time, the source voltage. The chlorine sensing system then measures, after the second time, an electrical parameter of the purified water. The chlorine sensing system determines the amount of total chlorine in the purified water based on the measured electrical parameter.Type: ApplicationFiled: August 14, 2023Publication date: November 30, 2023Inventors: Jeff White, Ye Chen, Yuanpang Samuel Ding, Joel Titus, Justin Rohde, Shincy Maliekkal, Kevin Cooper

Patent number: 11724012Abstract: A dialysis method and system for determining an amount of total chlorine in a partially purified water sample is disclosed. The system includes a water machine that produces at least partially purified water including an at least partially purified water sample and a dialysis machine that provides a dialysis treatment to a patient. The dialysis machine receives the at least partially purified water from the water machine to prepare dialysis fluid for the dialysis treatment. The system also includes a total chlorine detector configured to receive the at least partially purified water sample, at a first time apply a source voltage to the at least partially purified water sample, and at a second time stop applying the source voltage to the at least partially purified water sample and instead monitor a sensed electrical parameter to determine an amount of total chlorine in the at least partially purified water sample.Type: GrantFiled: October 4, 2021Date of Patent: August 15, 2023Assignees: Baxter International Inc., Baxter Healthcare SAInventors: Jeff White, Ye Chen, Yuanpang Samuel Ding, Joel Titus, Justin Rohde, Shincy Maliekkal, Kevin Cooper

Patent number: 10046099Abstract: A system and method for determining a concentration of total chlorine in dialysis water are provided. The system comprises a main unit housing an iodide/water sample chamber and a reducing agent chamber. An electrode pair bridges the two chambers and generates tri-iodide proportional to the amount of total chlorine in the dialysis water. The electrode pair detects the amount of tri-iodide generated in proportion to the amount of active chloride in the dialysis water. The system is suitable for use in connection with, or for incorporation into, a water purification system for generating dialysis fluid, and may include a display that alerts the user to stop or prevent a hemodialysis treatment if the total chlorine level exceeds a predetermined level.Type: GrantFiled: September 25, 2015Date of Patent: August 14, 2018Assignees: Baxter International Inc., Baxter Healthcare SAInventors: Jeff White, Ye Chen, Yuanpang Samuel Ding, Joel Titus, Justin Rohde, Shincy Maliekkal, Kevin Cooper

Patent number: 9757504Abstract: Systems and methods for performing hemodialysis to remove metabolic waste from the blood of a patient are disclosed. The systems and methods preferably comprise at least one blood processing apparatus that receives whole blood from a patient. Cellular blood components are removed from the whole blood by hemofiltration, to provide filtered plasma comprising metabolic waste that is substantially reduced of blood cells. The cellular blood components may be returned to the patient. The filtered plasma comprising waste may be removed from the blood processing apparatus through a waste path for further processing in a separate apparatus, or in the same apparatus in a second stage processing procedure to remove metabolic waste components and excess water from the plasma by hemodialysis. At least one of the hemofiltration and hemodialysis processing apparatus comprises a Taylor vortex-enhanced separation apparatus.Type: GrantFiled: January 12, 2015Date of Patent: September 12, 2017Assignees: BAXTER INTERNATIONAL INC., BAXTER HEALTHCARE SAInventors: Randolph H.
