혈액 진로내에서 체외 혈액을 계속적이고 온라인으로 모니터하기 위한 장치 및 방법이다. 셸은 혈액 유입포트와, 혈액 유출 포트와, 혈액 격실 및 혈장은 통과시키나 적혈구는 통과시키지 않는 반투과막에 의해 분리된 혈장격실인 두 개의 격실을 가지고 있다. 혈액은 혈액격실을 통하여 유동하고 투과막 압력은 혈장격실내의 혈장이 혈액격실을 통하여 유동하는 새로운 혈장으로 교체되도록 혈액격실과 혈장격실사이에 적용된다. 혈장격실내에서의 혈장의 색의 변화가 검출된다. An apparatus and method are disclosed for continuous, on-line monitoring of extracorporeal blood in a blood path. A shell (10) has a blood inlet port (14), a blood outlet port (16) and two compartments: a blood compartment (12) and a plasma compartment (18) separated by a semi-permeable membrane (20) that allows plasma to pass, but not red blood cells. Blood flows through the blood compartment (12) and transmembrane pressure is applied between the blood (12) and the plasma compartments (18) causing the plasma inside the plasma compartment (18) to be replaced by fresh plasma that is flowing through the blood compartment (12). Any color change of the plasma in the plasma compartment (18) can be detected.
