Publication number: 20230414871Abstract: A fluid therapy method for an ADHF patient includes setting a urine output rate desired threshold, setting one or more desired negative net gain rates, and optionally setting a total fluid loss goal. The urine output of the patient is monitored and fluid is automatically administered to the patient at increasing rates to equal to or approximately match the patient's increasing urine output rates until the patient's urine output rate reaches the set urine output rate desired threshold. Thereafter, fluid is administered to the patient at rates to achieve the set desired negative net gain rate until the fluid loss goal is reached. Thereafter, until the end of therapy, fluid is administered to the patient at rates equal to or approximately equal to the monitored urine output rates.Type: ApplicationFiled: May 23, 2023Publication date: December 28, 2023Inventors: Andrew V.

Patent number: 10045734Abstract: A console includes a weighing subsystem responsive to a first fluid source and a urine collection chamber. A pump infuses fluid from the first fluid source into a patient. A processing subsystem is responsive to the weighing subsystem. Based on the weight of the first fluid source and of the urine collection chamber, urine output and amount of fluid infused into the patient from the first fluid source are determined. A user can set a desired fluid balance and the amount of at least one additional fluid delivered. An actual fluid balance is calculated based on the determined urine output, the determined amount of fluid infused from the first fluid source, and the set amount of the additional fluid delivered. The pump is controlled based on actual fluid balance and set desired fluid balance so actual fluid balance becomes the same or approximately the same as the desired fluid balance.Type: GrantFiled: January 14, 2010Date of Patent: August 14, 2018Assignee: PLC Medical Systems, Inc.Inventors: J.
