Derivation of embolisms in fluid circulation

摘要

A method of diversion of an embolus during fluid circulation in an extracorporeal circuit which includes the steps of establishing a first circuit ( 100, 101 a, 101 b, 101 c, 102, 103, 104, 106 b, 106 a, 107 ) between an outlet of a vascular system and an inlet of said vascular system; establishing a 5 second circuit ( 101 b, 101 c, 102, 103, 104, 106 b, 108 ) configured to bypass said inlet and outlet; providing a fluid reservoir ( 102 ) a pumping means ( 103 ), and a bubble detector ( 105 ) in said circuits; detecting by means of said bubble detector ( 105 ) an embolus in said first circuit and sending a signal to an automatic embolus diversion supervisor ( 121 ) connected to said bubble detector ( 105 ); and controlling fluid flow direction means ( 110, 111 ) in dependence of the signal from said bubble detector ( 105 ); whereby said fluid flow direction means ( 110, 111 ) are controlled to redirect a detected embolus to said second circuit.
