IV Cannula Explained: Types, Sizes, Parts & Safety Cannula Guide for Medical Professionals

An IV cannula is a small and flexible medical device inserted into a vein to deliver fluids, medicines, or blood directly into the bloodstream. It is one of the most commonly used devices in hospitals, clinics, and emergency care.

From routine treatment to critical care, IV cannulas help doctors provide safe and continuous therapy without repeated needle pricks. Choosing the right cannula and a reliable iv cannula manufacturer is very important for patient safety and treatment success.

What Is an IV Catheter and How It Works

An iv catheter is a thin tube that remains inside the vein after insertion. During placement, iv catheter needles help guide the catheter into the vein.

Working Process of IV Needle and Catheter

The iv needle and catheter system works in two steps:

• A needle is used to enter the vein

• The catheter is placed inside the vein

• The needle is removed

• The catheter remains for fluid delivery

This process ensures safe and long-term access to the bloodstream.

Types of IV Catheters Used in Healthcare

Different iv catheter types are used depending on patient condition and treatment needs.

Peripheral IV Cannula

The most common type used for short-term treatments such as fluids, antibiotics, and medication.

Butterfly IV Catheter

A butterfly iv catheter is specially designed for small or fragile veins.

Key Benefits

• Better control during insertion
