摘要： An integrated CRRT method and apparatus incorporates steps and means for compensating for heat loss from blood in an extracorporeal circuit. A blood warmer is designed to engage and hold a disposable blood tube segment to transfer heat at a closely controlled temperature to blood flowing in the disposable blood tube segment. Another significant aspect of the present invention is a blood tube segment for engagement with the blood warmer is located in downstream of a dialyzer and upstream of a venous pressure monitor, an air bubble detector and a venous line clamp. The disposable blood tube segment may be selectively connected when heat loss compensation is required and left disconnected when heat loss compensation is not required.

摘要翻译： 集成的CRRT方法和装置包括用于补偿来自体外循环中血液的热损失的步骤和装置。 血液加热器被设计成接合和保持一次性血管部分，以在紧密控制的温度下将热量传递到在一次性血管部分中流动的血液。 本发明的另一个重要方面是用于与血液加热器接合的血管部分位于透析器的下游，并且位于静脉压监视器，气泡检测器和静脉管线夹具的上游。 当需要热损失补偿时，可以选择性地连接一次性血管部分，并且当不需要热损失补偿时将其断开。
