With advancements in materials, design, and manufacturing standards, IV cannulas have evolved into highly specialized devices that meet diverse clinical needs.

As a leading IV Cannula Manufacturer, Lars Medicare Private Limited delivers an extensive range of IV cannula solutions, including advanced safety features and precise engineering for enhanced performance. This guide provides an in-depth analysis of IV catheter types, sizes, parts, and innovations in manufacturing — serving as a reference for healthcare professionals, procurement teams, and distributors.

What is an IV Cannula?

An intravenous (IV) cannula is a flexible tube inserted into a vein using a sharp introducer needle to facilitate the direct administration of fluids and medications into the bloodstream. Once in place, the needle is withdrawn, leaving the cannula in situ for ongoing treatment.

The IV Needle and Catheter combination ensures a smooth insertion process and minimizes trauma to the vein wall. IV cannulas are available in a variety of designs, each catering to specific medical applications.

IV Cannula vs. IV Catheter

The terms IV Cannula and IV Catheter are often used interchangeably. Technically, the cannula refers to the flexible tube, while the catheter encompasses both the tube and the needle assembly used for insertion.

Modern IV Catheter Needles are engineered with precision tips and safety shields to reduce the risk of needlestick injuries, particularly in high-volume hospital environments.

Types of IV Cannula

There are several IV Catheter Types designed for different medical scenarios:

1. Peripheral IV Cannula – Commonly used for short-term therapies, placed in smaller veins of the hand or forearm.
2. Central Venous Catheter – Inserted into a large vein for long-term treatments or rapid infusion.
3. Butterfly IV Catheter – Features winged grips for easy insertion, ideal for quick infusions or pediatric patients.
4. Safety IV Cannula – Equipped with needle-protection mechanisms to prevent accidental injuries.

IV Catheter Sizes

Cannulas come in a range of IV Catheter Sizes, measured in gauge (G). A smaller gauge number corresponds to a larger diameter, which allows for faster fluid flow.

Parts of an IV Cannula

The IV Catheter Parts are designed for functionality, sterility, and patient comfort:

• Needle – Stainless steel introducer for vein penetration.
• Cannula Tube – Flexible polymer tube for fluid passage.
• Hub – Connection point for IV lines.
• Flashback Chamber – Indicates successful vein entry.
• Injection Port – Allows additional medication administration.
• Safety Clip or Shield – Prevents accidental needle exposure.
