Simple and Easy to Insert 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 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).
Shorter length may dislodge easily.
