What is the name of a device used to cannulate a blood vessel?

• A. Osmotic pump
• B. Tether
• C. Vascular access port
• D. Luer lock

Answer: (C)

Cannulation is about gaining repeated access to a blood vessel through a device that stays in place for easy entry. A vascular access port is designed for this purpose: it’s a small device implanted under the animal’s skin with a catheter that goes into a central vein. The port provides a reservoir that you can puncture through the skin with a needle to access the bloodstream, letting you administer fluids, medications, or draw blood without repeatedly sticking veins. This is different from an osmotic pump, which delivers drugs slowly from a implanted device over time; a tether is used to restrain or guide movement; and a Luer lock is simply a type of connection interface used to attach syringes or tubing, not a cannulation device itself.
