Abstract
A fluid mixing and delivery system including a fluid injector to receive first and second fluids to be mixed together so that the resultant mixture can be delivered to a target site. The injector has particular application for introducing two fluid adhesive reagents to one another to produce a biomedical glue suitable to seal or plug a skin graft, wound, tear or minor break in the tissue or bone of a patient. The injector has a proximal end at which to receive the first and second fluids under pressure and a distal end at which the first and second fluids are mixed together within a common canal and expulsed therefrom by way of an exit tip. The common canal has a diameter that expands from narrow to wide in the direction of the mixture flowing therethrough to create a Per de Lavel anti-clogging nozzle and a Venturi effect at the exit tip so as to avoid a bottle neck blockage.
