A sprayer for dispensing fibrinogen and thrombin to form fibrin glue immediately away from the sprayer to prevent clogging and insure accurate precise metering. The sprayer includes a pistol grip area, a barrel and a trigger which moves a plunger support that captures the plunger of a syringe. One syringe holds thrombin and the other syringe holds fibrinogen. Each syringe communicates with an outlet having an atomizer.

[ We claim:] [1.] A gun for dispensing fibrin glue formed from thrombin and fibrinogen, where both the thrombin and the fibrinogen are respectively sequestered in independently operable syringes, the syringes each having a plunger which reciprocates within a hollow of a body of the syringe and an outlet on the syringe body remote from the plunger, said gun comprising in combination:a barrel,means for supporting each of the syringes on said barrel of said gun,means for constraining the plungers of each syringe to control each plunger's reciprocation within its syringe,said plunger constraining means operatively coupled to a trigger located on a handle said handle attached to said barrelmetering means between said trigger and said plunger's constraining means to control the degree to which the plungers are depressed within the hollows of the syringes to thereby precisely meter the outflow from each syringe such that a standardized quanta of fibrinogen and thrombin are dispensed with each trigger pull, andfirst and second dispensing means on said barrel, one for each syringe, said dispensing means operatively coupled to the outlets of their respective syringes whereby motion of the plungers by said trigger dispenses the contents of each said syringe.
