Clot formation is a common complication in extracorporeal circuits. In this paper we describe a novel method for clot formation analysis using image processing. We assembled a closed extracorporeal circuit and circulated blood at varying speeds. Blood filters were placed in downstream of the flow, and clotting agents were added to the circuit. Digital images of the filter were subsequently take...

The aim of the study was to develop a method for determination activity thrombin, which is based on turbidimetry curve formation and dissolution blood plasma clot. Methods. Donor samples were collected in 3.8% sodium citrate (1 part 9 parts blood, pH 7.4). Plasma separated from cells within 1 hour after collection by centrifugation latter at 1200 g 20 minutes. Aliquots stored -20 °C. Results. T...

Inferior vena cava (IVC) filters have become essential components in deep vein thrombosis treatment, and are particularly critical for preventing pulmonary embolisms in anticoagulation-resistant patients. Filter efficacy relies on maintaining IVC patency, or openness, by preventing filter-induced thrombosis following clot capture. A computational fluid dynamics (CFD) model has been developed to...
