The utility model patent with announcement number CN220110177U discloses a urinary catheter capable of measuring bladder pressure. The technical scheme is as follows: it comprises a urinary catheter main pipe, a tube body 1 is fixedly connected to the top of the urinary catheter main pipe, a tee pipe is arranged on the outer side of the top of the tube body 1, and the bottom end of the tee pipe extends to the inside of the tube body 1. The beneficial effect of the utility model is as follows: physiological saline can be added to the inside of the tube body 1 and the urinary catheter main pipe through the side pipe of the tee pipe, and after the addition is completed, the side pipe of the tee pipe can be closed by rotating the control valve, and then the vertical passage of the tee pipe is opened, and then the main pipe of the urinary catheter and the tube body 1 can be connected to the atmosphere under the action of the tee pipe, and then after the water surface of the physiological saline is stable, the water surface is observed at the scale line, and then the height of the water surface can be read, thereby directly measuring the patient's bladder pressure. In this way, the device has the function of measuring the patient's bladder pressure, and the doctor does not need to use other tools to measure the patient's bladder pressure.
[0003] However, the existing intrauterine drainage tubes still have certain shortcomings: first, most of the existing intrauterine drainage tubes use simple drainage hoses to drain the liquid inside the uterine cavity, which is easy to cause discomfort due to the influence of factors such as the material of the drainage hose itself;
