An IV catheter is a thin, flexible tube inserted into a vein to deliver fluids, medicines, or blood directly into the bloodstream. It is one of the most important tools in hospitals, clinics, and emergency care.
Doctors and nurses rely on IV catheters to provide safe, controlled, and continuous treatment without repeated needle insertion.
The IV needle and catheter system works in two stages. First, a needle helps insert the catheter into the vein. Once placement is confirmed, the needle is removed, and only the soft catheter remains.
This design improves patient comfort and allows long-term access to the vein.
Different IV catheter types are used depending on treatment needs.
The most commonly used catheter for routine fluids, antibiotics, and short-term therapy.
A butterfly IV catheter is designed for small or fragile veins. It is often used for children, elderly patients, or blood collection.
A Safety IV Cannula includes a protective mechanism that reduces the risk of needlestick injuries and improves healthcare worker safety.
IV catheter sizes are measured in gauge numbers and color-coded for easy identification. Choosing the right size ensures correct flow rate and reduces vein damage.
Size selection depends on:
Patient age and vein condition
Type of medication or fluid
Emergency vs routine treatment
Duration of IV therapy
Understanding IV catheter parts helps in safe handling and correct insertion.
Key components include:
Flexible catheter tube
Stainless steel insertion needle
Hub for connection
Flashback chamber
