摘要

Disclosed is a urinary catheter with an automatic pressure relief function, comprising a urinary catheter body (1), a urinary catheter connection piece (2), a pressure relief valve (3) and a urine bag (4). One end of the urinary catheter connection piece (2) is connected to the urinary catheter body (1). The other end of the urinary catheter connection piece (2), the pressure relief valve (3) and the urine bag (4) are successively connected by a urination hose (5). The urine bag (4) is provided with a discharge valve (6). The urinary catheter has a simple structure. The pressure relief valve (3) automatically relieves pressure. When the set bladder pressure is reached, urination is automatically performed. It is convenient for clinical use, while preventing bladder injuries resulting from a long indwelling urinary catheter.
