The invention provides a handheld, manually operable fluid applicator, particularly suited to the needs of surgeons, which can dispense multiple medically useful fluids, for example fibrin and thrombin components of a tissue adhesive, and which has a smooth feel and action. The applicator has a novel actuator mechanism providing a comparatively higher mechanical advantage in a commencement phase of the actuator stroke and a comparatively lower mechanical advantage in a completion phase of the actuator stroke.
[ We claim:] [1.] A manually actuated fluid applicator having:a) a fluid container to contain fluid;b) a movable actuator having an actuator stroke and being repeatedly operable by a manually applied force on the movable actuator to dispense fluid from the applicator by displacement of fluid from the fluid container, the actuator stroke having a commencement phase and a completion phase; andc) a drive mechanism to translate the manually applied force on the movable actuator to a fluid displacing force exerted on fluid in the fluid container; rein the mec...
