摘要：
Flush syringe assemblies (100) capable of creating pulsatile movement of the plunger rod (130) as it moves in the distal direction within a syringe barrel (110), while preventing overpressurization of the cathether are provided. An exemplary flush syringe assembly includes a syringe barrel with a first pulsing element (126) and a chamber (115) with flush solution, a plunger rod with a stopper (160) and a second pulsing element (136) that interacts with the first pulsing element to provide an engagement force that causes pulsatile movement of the plunger rod and a thumb press (170) slidably attached to the plunger rod with a pulse control element (190). The pulse control element is compressible to create a compression force that is greater than the engagement force of the first pulsing element and the second pulsing element.
