Abstract:
A single use system for obtaining autologous plasma and applying a fibrin gel 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; anda flow path along the membrane between the first and second pumps;whereby whole blood can be repeatedly exchanged between the receiving chambers in the first and second pumps, past the membrane, to allow plasma to flow across the membrane and out of the outlet; andan 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;a manifold in communication with the first and second injectors for applying the thrombin solution and plasma simultaneously to site on a body.
