CATHETERS

摘要

A catheter for use in a urine collection system has a hollow tube forming a suprapubic section (1), a bladder section (2) and a urethral section (3). There are drainage holes in the bladder section (2) and optionally either or both of an abdominal stop (5) and a non-return cuff (6) on the bladder section (2) which holds the catheter in place. There may also be a valved drainage section (31) extruding from the suprapubic section (1) to a drainage outlet (32), or a urine collection bag (35). The drainage section (31) and/or the suprapubic section (1) may have a pH sensor therein. There may also be a urine collection container (12) connected to the suprapubic section (1) the connection forming a closed valve-free fluid flowpath from the bladder section to the urine collection container and from the urine collection container to the bladder section, whereby the urine collection container provides a low pressure reservoir.
