    Abstract: A fluid replacement system comprising: a subsystem (12) for determining an amount of fluid infused (50) into a patient from a first fluid source (16); a pump (18) configured to pump fluid from the first fluid source (16) into the patient; the subsystem (12) also for determining a patient's urine output (52); a user interface (22) including means for setting a desired positive, negative, or zero fluid balance (58) for the patient; and a processing subsystem (20) responsive to a set desired positive, negative, or zero fluid balance (58), and the subsystem (12) and configured to: determine the patient's urine output (52) and the amount of fluid infused (50) into the patient from the first fluid source (16), control the pump (18) to adjust the operation of the pump (18) based on the patient's urine output (52) and the amount of fluid infused (50) into the patient from the first fluid source (16), calculate an actual fluid balance (56) based on the determined urine output (52) and the determined amount of fluid infused (50) into the patient from the first fluid source (16), control the pump (18) based on the actual fluid balance (56) and a set desired negative fluid balance (58) so the actual fluid balance (56) becomes the same as or approximately the same as the desired negative fluid balance (58), when the desired fluid balance (58) is negative and the urine output (52) is less than the set desired negative fluid balance (58) over a first established time interval, control the pump (18) to infuse fluid from the first fluid source (16) into the patient at a preset rate, and when the urine output (52) is greater than the set desired negative fluid balance (58) over a second established time interval, control the pump (18) to infuse fluid from the first fluid source (16) into the patient at a rate which achieves the set desired negative fluid balance (58) based on the urine output (52) during said second established time interval.

    Abstract translation: 流体置换装置及方法。 控制台包括响应于第一流体源和尿液收集室的称重子系统。 泵配置成将来自第一流体源的流体输入到患者体内。 控制台中的处理子系统响应称重子系统。 基于第一流体源的重量和尿液收集室的重量，确定患者的尿量和从第一流体源输入到患者体内的液体量。 控制台中的用户界面允许用户为患者设置所需的流体平衡以及递送给患者的至少一个附加流体的量。 基于确定的尿液输出，从第一流体源输入到患者中的液体的确定量以及递送给患者的至少一种额外流体的设定量来计算实际流体平衡。 基于实际流体平衡和设定的所需流体平衡来控制泵，使得实际流体平衡变得与期望的流体平衡相同或大致相同。
