How to make a safe urinary catheter and urinary catheter

摘要

The urinary catheter can include a catheter shaft and a connector coupled to the proximal end of the catheter. The connector may include a first arm ending at a fluid outlet configured to allow urine to flow out of the urinary catheter, and a second arm having an opening ending at the inlet inlet used to introduce the inflation fluid into the urinary catheter. The catheter may further include a main lumen, an expansion lumen, a retaining balloon proximate the fluid inlet and mounted to the catheter shaft above the distal filling hole, and a pilot balloon mounted on the second arm of the connector above the opening. The pilot balloon expands at an inflation pressure that is above the inflation pressure of the holding balloon and below a predetermined pressure threshold.
