Apparatus and methods for providing controlled pressure-flow pulses which purge a catheter system with turbulent flow flushing. Accomplishment of such controlled pressure- flow pulses is provided by a variety of inventive devices including a special plunger rod for a conventional syringe, other interactive parts for conventional syringes, an in-line catheter attachable device which automatically generates the controlled pressure-flow pulses and also single pulse, digitally operated devices.
L'invention porte sur un appareil et des procédés de délivrance d'impulsions de flux à pression commandée purgeant un système de cathéter avec un rinçage à écoulement turbulent. La mise en uvre de telles impulsions d'écoulement à pression commandée est fournie par une pluralité de dispositifs de l'invention comprenant une tige de piston spéciale pour seringue classique, d'autres parties interactives pour seringues classiques, un dispositif pouvant être fixé de cathéter en ligne générant automatiquement des impulsions d'écoulement à pression commandée et également des dispositifs manuels délivrant une impulsion unique.
