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).
