Introduction

Intravenous (IV) cannulas are indispensable in modern medicine for the administration of fluids, medication, and for sampling blood. A specialized version, the 3-way IV cannula, offers enhanced functionality by allowing multiple lines of access through a single cannulation site. This article covers its mechanism, technical specifications, and industry solutions from Conpuvon Company.

Mechanism of 3-Way IV Cannula

The 3-way IV cannula functions by incorporating an additional port that enables simultaneous administration of multiple treatments. The primary component is a Y-shaped connection, which includes:

• Main Cannula: The primary entry point into the vein that connects to the IV line.
• Secondary Port: A lateral opening providing an additional channel for fluid administration.
• Stopcock Valve: Integrated to control and adjust the flow direction and rate between the main line and secondary port.

This design minimizes the need for multiple punctures, reducing patient discomfort and streamlining medical procedures.

Technical Specifications

The 3-way IV cannula is available in various sizes and materials to cater to diverse medical needs:

• Gauge Sizes: Typically ranges from 18G to 22G, balancing flow rate and vein compatibility.
• Flow Rate: Between 20 - 150 mL/min, depending on gauge and patient vascular condition.
• Material: Composed of biocompatible plastic, often Polytetrafluoroethylene (PTFE) or polyurethane.
• Length: Ranges from 20 to 45 mm to suit different sites of cannulation.
• Sterilization: Typically sterilized using Ethylene Oxide (EtO) or Gamma radiation to ensure patient safety.
