Title:
血液処理システムにおける漏れ検出のための改善方法及び装置
Document Type and Number:
Japanese Patent JP4416797
Kind Code:
B2
Abstract:
A flow reversing device for performing blood treatment can include a flow reversing actuator. The flow reversing actuator can receive and engage a disposable tubing set with multiple branches that form forward and reverse blood flow paths respectively when blood the flow reversing actuator is selectively changed between forward and reverse configurations. The shape of the tubing can be such that during forward operation, dead regions of non-flowing blood are defined. The flow reversing actuator can have a controller configured to operate generally in forward mode. At first times, the controller can cause the flow reversing actuator to clear the dead regions. At second times, the controller can cause the flow reversing actuator to test for leaks by reversing the flow of blood for a period of time sufficient to cause air to be drawn into the tubing set and conveyed to an air sensor.
