A contrast fluid delivery method and
system includes a multiple-reuse filling section for attachment by conduit to a contrast
fluid supply container, and a delivery section that is removably attached to the filling section for delivering contrast fluid held in the filling section to a patient. The filling section includes a main body having a fluid chamber, a contrast fluid filling inlet with a gravity-operated valve, an opening for connecting an operable power
syringe, and a contrast fluid outlet fed through a spring-loaded one-way
check valve. The delivery section includes a first delivery conduit connected between the contrast fluid outlet of the main body and the fluid inlet of an inline
aspirator syringe, and a second delivery conduit connected at one end to a fluid outlet of the
aspirator syringe and at the other to a
catheter for delivering the contrast fluid to a patient. The
aspirator syringe includes a spring-loaded
plunger that is operatively depressed and released to confirm and assure patency of the delivery line before sustained injection of the desired volume of contrast agent. The filling section is isolated from
contamination by the downstream delivery section and may be used repeatedly for successive patients, whereas the delivery section is discarded and replaced after each patient use.
