Controlled Infusion of Radiopharmaceutical Agent Using a Peristaltic Pump

Begin with a peristaltic infusion system assembled for radiopharmaceutical delivery.

The pump is loaded with an infusion cassette.

The cassette’s line A is connected to a saline bag and line B to a saline-purged spinal needle.

Connect the pump’s output tubing to the patient’s catheter.

Next, position a lead-shielded barrier in front of the pump to reduce radiation exposure to the operator.

Place a lead container holding the radiopharmaceutical vial on the barrier’s tray and remove its cap.

Disinfect the vial septum. Insert a venting filter, ensuring its tip remains above the liquid to prevent vacuum formation.

Then, insert the spinal needle from line B into the septum, directing the tip to the bottom of the vial.

Start the infusion. The pump draws saline through line A and radiopharmaceutical through line B and delivers them to the patient in a controlled manner.

To begin, insert the infusion set spike into the inlet of the 250 milliliter sodium chloride 0.9 percent bag. Apply gentle pressure to fill the infusion chamber three-quarters full.

Turn the perfusion set cassette upside down, declamp the infusion set, and slightly unscrew the flow regulator. As soon as the first drops of saline ent
