摘要： The invention provides a handheld, manually operable fluid applicator, particularly suited to the needs of surgeons, for dispensing a multi-component fluid applicator, for example fibrin and thrombin components of a tissue adhesive. The sealant components undergo turbulent mixing in a mixing chamber (58) to provide effective mixing, and a quality sealant product. The mixing chamber (58) has an increased cross-sectional area over the combined areas of the component supply passages, and the fluid flows are directly opposed to impinge on each other in the mixing chamber (58). The mixing chamber (58) is incorporated in a novel one-piece flexible, and resilient manifold (52). Dual nozzle spray applicators with poppet valves are also disclosed.

摘要： A medical fluid applicator (1) for dispensing a fluid onto biological tissues in tissue adhesive or sealant applications includes a dispensing pathway (5) with an audible loudness indicator (200) that signals the cumulative amount of fluid delivered by varying the pitch or tone of audible signals emitted at discrete volumetric increments. A suction pathway (7) is also included for applying vacuum pressure to the applicator tip (10) contemporaneous with the fluid application. The medical fluid applicator (1) further includes a clearing pathway (8) for retrogradely withdrawing coagulated mixed fluids, such as mixed two-part tissue adhesives from the applicator tip (10).
