a barrel having a sidewall extending from a proximal end to a distal end and defining a chamber accommodating a fluid;
a syringe tip disposed at the distal end of the barrel, the fluid exiting the barrel through the syringe tip; and
a wheel configured in the chamber to rotate due to a rotational velocity component in a flow of the fluid from the chamber, and periodically block and unblock the flow of the fluid from the chamber out of the syringe tip, producing a pulsatile flow in the flow of the fluid from the chamber out of the syringe tip,
wherein the wheel comprises inclined vanes inducing the rotational velocity component in the flow of the fluid.
