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.

[ What is claimed is:] [5.] A system for obtaining autologous plasma comprising:a plasma separator for separating plasma from whole blood, the plasma separator comprising:a single use filter unit comprising a first inlet and a second inlet in fluid communication with each other, an outlet, and a filtration membrane separating the inlets from the outlet, the filtration membrane being selectively permeable to blood plasma;a manually operable, single use first pump comprising a receiving chamber connected to the first inlet, the receiving chamber having a manually moveable wall for altering the volume of its receiving chamber;a manually operable, single use second pump comprising a receiving chamber connected to the second inlet and a manually moveable wall for altering the volume of its receiving chamber;a flow path along the membrane between the first and second pumps;an applicator for preparing and applying fibrin gel in a medical procedure, the applicator comprising:a first injector containing a thrombin solution;a second injector containing the plasma, the plasma containing an amount of fibrinogen; anda manifold in communication with the first and second injectors for applying the thrombin solution and plasma simultaneously to a site on a body; anda sealed sterile package containing the plasma separator, the fibrin applicator; and instructions for obtaining whole blood from a patient, separating plasma from the whole blood by manually pumping the whole blood in alternating fashion along the membrane, and simultaneously applying the plasma thus collected along with a solution of thrombin to a site on a body.
