Bladder and urethra synchronous pressure measurement pipe with memory metal basket-shaped fixing device

The invention discloses a bladder and urethra synchronous pressure measurement pipe with a memory metal basket-shaped fixing device. The bladder and urethra synchronous pressure measurement pipe comprises a catheter body which is composed of a bladder irrigation pipe, a bladder pressure measurement pipe, a urethra pressure measurement pipe and guide wire pipes, wherein the bladder irrigation pipe, the bladder pressure measurement pipe, the urethra pressure measurement pipe and the guide wire pipes are independent of one another. Guide wires are arranged in the guide wire pipes respectively. Groove holes communicated with the corresponding guide wire pipes are formed in the positions, located between a bladder irrigation port and a bladder pressure measurement port and corresponding to the positions of the guide wire pipes, of the side wall of the catheter body in the longitudinal direction. Hollow guide columns are fixed to the rear port of the catheter body. The bladder irrigation pipe, the bladder pressure measurement pipe and the urethra pressure measurement pipe penetrate through hollow guide columns to be communicated with corresponding pipe connectors respectively. Positioning grooves are formed in the side walls of the front ends of the hollow guide columns in the circumferential direction. The hollow guide columns are sleeved with a slide ring in a sliding mode. Protruding blocks matched with the positioning grooves are arranged on the inner ring face of the slide ring. The rear end of each guide wire is fixedly connected with the slide ring. The bladder and urethra synchronous pressure measurement pipe is not influenced by the body position change of a patient or the urination interference, and test data are accurate and reliable.
