A urinary catheter is a thin, flexible tube used to drain urine from the bladder. Its key components include:
Main Components:
-
Catheter Tube: This is the main body of the catheter, typically made of a flexible material like silicone or latex. The reference describes it as "a thin, flexible rubber or plastic tube that goes through your urethra into your bladder." This tube facilitates the drainage of urine.
-
Drainage Port: This is one of the "two separate pathways" mentioned in the reference. It's the opening through which urine flows from the bladder into a collection bag or device.
Additional Considerations (depending on catheter type):
Some catheters may have additional components, depending on their design and purpose:
-
Balloon: Many indwelling catheters (those left in place for a period of time) have a balloon near the tip. This balloon is inflated after insertion to anchor the catheter securely in the bladder. The balloon is inflated with sterile water or saline.
-
Connectors: These connect the catheter to a drainage bag or other collection system. The type of connector varies.
-
Eyes or Perforations: Near the tip of the catheter are small holes or "eyes" which allow urine to flow into the catheter tube from the bladder.
While the provided reference only specifically mentions the catheter tube and the drainage port, understanding the broader context of different catheter types requires knowledge of additional components. These components ensure proper function and patient safety.
