Types of Cannulas Used in Medical Labs: A Comprehensive Overview

Summary

• There are various types of cannulas used in medical labs for different purposes.
• The four main types of cannulas are winged infusion cannulas, angiocath cannulas, over-the-needle cannulas, and IV cannulas.
• Each type of cannula has its own unique design and is used for specific medical procedures.

Introduction

Cannulas are thin tubes that are inserted into a vein or body cavity to administer medication, draw blood, or perform other medical procedures. In medical labs, cannulas are commonly used for a variety of purposes, and different types of cannulas are used depending on the specific procedure being performed. In this article, we will discuss the different types of cannulas used in medical labs and their unique characteristics.

Types of Cannulas

Winged Infusion Cannulas

Winged infusion cannulas, also known as butterfly needles, are small, thin tubes with flexible wings on the sides. These cannulas are used for drawing blood, administering medication, or performing intravenous (IV) procedures. Winged infusion cannulas are ideal for patients with small or fragile veins, as they cause minimal trauma during insertion. The wings on the cannula allow for better control and stability during the procedure, making it easier for healthcare professionals to perform the necessary tasks.

2. Ideal for patients with small or fragile veins
3. Used for drawing blood, administering medication, and performing IV procedures

Angiocath Cannulas

Angiocath cannulas are straight, hollow tubes with a sharp needle at one end and a plastic hub at the other end. These cannulas are commonly used for inserting into veins or arteries for drawing blood, administering fluids, or performing other medical procedures. Angiocath cannulas come in various sizes to accommodate different patients and procedures. The sharp needle allows for easy and quick insertion into the vein, while the plastic hub provides a secure connection for attaching tubing or syringes.

1. Straight, hollow tubes with a sharp needle
2. Used for inserting into veins or arteries
3. Come in various sizes for different patients and procedures

Over-the-Needle Cannulas

Over-the-needle cannulas are short, hollow tubes that are inserted into a vein or body cavity over a sharp needle. Once the cannula is in place, the needle is removed, leaving only the tube in the vein. Over-the-needle cannulas are commonly used for drawing blood, administering medication, or performing IV procedures. These cannulas are designed to minimize trauma to the vein during insertion and provide a secure connection for attaching other medical devices.

1. Short, hollow tubes inserted over a sharp needle
2. Needle is removed once cannula is in place
3. Used for drawing blood, administering medication, and performing IV procedures

IV Cannulas

IV cannulas, also known as intravenous catheters, are long, flexible tubes that are inserted into a vein for administering fluids, medication, or blood products. These cannulas come in various sizes and are often used for longer-term access to the bloodstream. IV cannulas are secured in place with tape or a securement device to prevent dislodgement or leakage. They are commonly used in hospital settings or urgent care clinics for delivering intravenous therapy to patients.

2. Used for longer-term access to the bloodstream
3. Secured in place with tape or securement device

Conclusion

In conclusion, there are several types of cannulas used in medical labs for various procedures. Winged infusion cannulas, angiocath cannulas, over-the-needle cannulas, and IV cannulas each have their own unique characteristics and are used for specific medical tasks. Healthcare professionals must choose the appropriate cannula for each procedure to ensure optimal patient care and safety.
