What is the difference between a cannula and an Venflon?

A cannula, which is commonly referred to as a Venflon, is a small flexible plastic tube that is inserted through the skin into one of your veins. If it is inserted in a very clean way (aseptic) and, if free from other complications, it can stay in for 3 days.

Traditionally, syringes with at least a diameter of 10 mL are recommended for long-term central venous catheters. However, this issue arises only when force applied meets resistance. Flushing with a small syringe diameter or with high force applied to the plunger in cases of resistance increases the risk of catheter damage.
