Katétr

Katétr is a medical device that is typically a thin, flexible tube. It is commonly used to introduce fluids into, or remove fluids from, the body. The material of a katétr can vary, but it is often made from medical-grade plastics, rubber, silicone, or polyurethane.

One of the most common uses for a katétr is in urinary catheterization. A urinary katétr is inserted into the bladder through the urethra to drain urine. This can be necessary for individuals who are unable to urinate on their own due to illness, injury, or surgery. There are different types of urinary katétre, including intermittent catheters, which are used for short-term drainage, and indwelling catheters, which remain in place for longer periods.

Katétre are also employed in various other medical procedures. For example, they can be used to administer medication directly into a specific part of the body, such as in chemotherapy. In cardiology, catheters are used for diagnostic procedures like angiography, where they are guided through blood vessels to visualize arteries. They can also be used to deliver treatments, such as angioplasty to open blocked blood vessels. Furthermore, catheters find applications in surgery, for example, to drain fluid collections or to assist in the insertion of other surgical instruments. The size and design of a katétr are specific to its intended use and the anatomical location.
