Dialyysiputki

Dialyysiputki, also known as a dialysis catheter or fistula needle, is a medical device used in hemodialysis treatment. Hemodialysis is a procedure that artificially filters waste products and excess fluid from the blood when a person's kidneys are unable to perform these functions adequately. Dialyysiputki is crucial for accessing the bloodstream safely and efficiently during these treatments.

There are several types of dialyysiputki. The most common are temporary catheters, often inserted into a large vein in the neck or chest, and permanent catheters, which are surgically placed for longer-term use. Another important access method involves arteriovenous fistulas (AVF) or arteriovenous grafts (AVG), where specialized needles, often referred to as dialysis needles or fistula needles, are inserted into the AVF or AVG to draw blood for dialysis and return it to the body. These needles have specific designs to facilitate efficient blood flow without damaging the vascular access.

The primary function of dialyysiputki is to create a conduit for blood to be removed from the body, passed through a dialyzer (artificial kidney) for filtration, and then returned to the body. Proper insertion, care, and maintenance of the dialyysiputki are essential to prevent complications such as infection, blood clots, or damage to the blood vessels. Healthcare professionals, such as nurses and interventional radiologists, are trained in the insertion and management of these vital medical devices. The choice of dialyysiputki depends on factors such as the patient's medical condition, the duration of dialysis treatment, and the availability of vascular access.
