An A.V. fistula needle, also known as an arteriovenous fistula needle, is a crucial medical device in hemodialysis treatment. It is designed to access the patient's arteriovenous fistula, which is a surgically created connection between an artery and a vein, usually in the forearm.
The needle consists of a sharp, slender tip that allows for precise puncture of the fistula. It is attached to a tubing system that connects to the hemodialysis machine. The size and gauge of the needle may vary depending on the patient's specific needs and the characteristics of their fistula.
This type of needle enables efficient blood flow from the patient's body to the dialysis machine for the removal of waste products and excess fluids, and then the return of cleansed blood. Its proper use and insertion technique are essential to ensure the success of hemodialysis sessions while minimizing the risk of complications such as bleeding, infection, or damage to the fistula. Healthcare providers are trained to handle A.V. fistula needles with care and precision to provide optimal patient care during hemodialysis procedures.
