Abstract

A system for preparing autologous plasma comprises a single use filter unit having two inlets in fluid communication with each other, an outlet, and a filtration membrane selectively permeable to blood plasma separating the inlets from the outlet. Manually operable, single use pumps, preferably syringes, connect to the inlets. A flow path is defined along the membrane between the pumps, whereby, whole blood can be repeatedly exchanged between the two pumps, past the membrane, to cause plasma to flow across the membrane and out of the outlet. A syringe can collect plasma from the outlet. Plasma thus collected can be simultaneously applied with a thrombin solution to a site on the body, thereby forming a fibrin gel.
