INTRAVENOUS CANNULA

About INTRAVENOUS CANNULA

An intravenous cannula is a sterile, flexible device inserted into a vein to provide a continuous or intermittent access point for the administration of fluids, medications, or blood products. It is a critical component in vascular access, used in emergency care, surgical settings, inpatient wards, and outpatient therapy.

Key Features:

• Cannula (Catheter) Tube:

  • Made of medical-grade, biocompatible polyurethane or Teflon.

  • Flexible and kink-resistant, designed to remain in the vein comfortably for short to medium durations.

• Stainless Steel Introducer Needle:

  • Sharp beveled tip for smooth and atraumatic venipuncture.

  • Needle is withdrawn after successful insertion, leaving only the soft cannula in place.

• Flashback Chamber:

  • Located at the needle hub to confirm venous access via blood flashback.

• Luer Lock or Luer Slip Hub:

  • Color-coded according to gauge size (e.g., pink = 20G, green = 18G) for quick identification.

  • Enables secure connection to IV lines, syringes, or infusion sets.

• Injection Port (Optional):

  • Integrated port with a valve for administering medications without disconnecting the main line.

• Wings (Optional - Winged Cannula):

  • Aid in securing the cannula with tape and enhance patient comfort and stability.

• Safety Features (in safety IV cannulas):

  • Built-in needle protection mechanisms to reduce the risk of needlestick injuries.
