FLUID REPLACEMENT DEVICE

摘要

A fluid replacement device and method. A console includes a weighing subsystem responsive to a first fluid source and a urine collection chamber. A pump is configured to infuse fluid from the first fluid source into a patient. A processing subsystem in the console is responsive to the weighing subsystem. Based on the weight of the first fluid source and the weight of the urine collection chamber, the patient's urine output and the amount of fluid infused into the patient from the first fluid source are determined. A user interface in the console allows the user to set a desired fluid balance for the patient and the amount of at least one additional fluid delivered to the patient. An actual fluid balance is calculated based on the determined urine output, the determined amount of fluid infused into the patient from the first fluid source, and the set amount of the at least one additional fluid delivered to the patient. The pump is controlled based on the actual fluid balance and the set desired fluid balance so the actual fluid balance becomes the same as or approximately the same as the desired fluid balance.
