<p>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.</p> |
