What is needle canula?

A needle cannula is a thin, hollow tube that is usually inserted subcutaneously to administer medication or withdraw fluids from the body. The needle cannula can be made of either metal or plastic, and it typically has a sharp end and a blunt end. The sharp end is used to penetrate the skin and access the subcutaneous tissue, while the blunt end is used to administer or withdraw fluids.

Needle cannulas are commonly used in a variety of medical settings, including hospitals, clinics, and doctor's offices, to deliver medications, draw blood, or collect other samples for diagnostic testing. They are also used in veterinary medicine for a variety of procedures.

Some of the key considerations when choosing a needle cannula include the gauge size and length of the needle, as well as the type of material it is made of. The gauge size refers to the thickness of the needle, with smaller gauges being thinner and larger gauges being thicker. The length of the needle can also vary, depending on the specific application. Additionally, some needle cannulas are disposable, while others are designed to be reused after sterilization.
