Abstract:
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.

Claim (Index 13):
A plunger rod, which in combination with an attached plunger of a syringe, is used to displace liquid within a syringe barrel which has a proximally disposed retention ring which provides opportunity for a tactile indication of a discernable stop to indicate a limit of proximal displacement of the plunger and plunger rod within the barrel, said plunger rod comprising:\n an elongated stem disposed between said plunger and a proximal end of the stem; an entry disk proximally disposed relative to the plunger on said stem for interacting with the retention ring; plurality of actuating geometry disposed along the stem, the plurality of actuating geometry obstructed by the retention ring such that displacement of the plurality of actuating geometry past the retention ring creates acceleration and velocity within the syringe barrel; and a reminder ring proximal to the plurality of actuating geometry which is sized and shaped to require a force to move the reminder ring past the retention ring which is greater than a force required to move the plurality of actuating geometry past the retention ring, providing a tactile indication that the acceleration and velocity within the syringe barrel resulting from actuation using the reminder ring is a last acceleration and velocity created within the syringe barrel.
