IV cannula

1. Pen-Type IV Cannula (Standard IV Cannula)
Design: Straight, pen-like design without additional features.

Uses: General IV access for fluids, medications, or blood draws.

Advantages: Simple, easy to insert, commonly used in hospitals.

Disadvantages: No extra ports, may require additional needle sticks for injections.

2. IV Cannula with Injection Port
Design: Similar to a standard IV cannula but has a side port (usually a latex-free injection port) for medication administration.

Uses: Allows bolus injections or secondary IV lines without disconnecting the main IV line.

Advantages: Reduces the need for additional needle sticks; convenient for intermittent drug delivery.

Disadvantages: Slightly bulkier than a standard cannula.

3. Butterfly IV Cannula (Winged Infusion Set)
Design: Short, thin needle with plastic "wings" for stabilization and a flexible tubing with a connector.

Uses:

Pediatrics, elderly patients, or fragile veins (small veins).

Short-term infusions or blood draws.

Advantages:

Better control during insertion due to wings.

Less traumatic for delicate veins.

Disadvantages:

Not ideal for long-term IV therapy (higher risk of infiltration).

A shorter length may dislodge easily.
