Common uses of a cannula include:

  • Fluid administration

  • Medication delivery

  • Blood transfusion

The IV needle and catheter work together during insertion, after which only the catheter remains inside the vein.

Different IV catheter types are available to match various medical needs and patient conditions.

Peripheral Cannula

Used for short-term treatments such as hydration and antibiotics.

Butterfly Cannula

A butterfly IV catheter is ideal for small or fragile veins, especially in children and elderly patients.

Safety Cannula

A Safety IV Cannula is designed to reduce needlestick injuries by automatically covering or locking the needle after use.

Understanding Cannula Sizes

IV catheter sizes are identified by gauge numbers and color coding. Selecting the correct size helps ensure safe and effective treatment.

Cannula size selection depends on:

  • Type of therapy
