Design and application of an indwelling urinary catheter with the function of preventing traction injury caused by unplanned removal of catheter

Given the severity of illness conditions, most ICU patients require placement of indwelling urinary catheters for a long time. In order to enhance patient safety during catheter retention, reduce urethral injury and bleeding caused by unplanned catheter removal, and lower catheter-associated urinary tract infections, this paper introduces the design and application of a indwelling urinary catheter with the function of preventing traction injury. The aim is to effectively reduce urethral injury during unplanned catheter removal, decrease the risk oif urethral bleeding and pain, and lower the incidence of catheter-associated urinary tract infections.
