The invention belongs to the technical field of electrochemical sensors, and relates to an electrochemical sensor for detecting the ion content in urine by taking ZIF-8 as a center, a detection method and an antibacterial catheter. An electrode array is arranged in the electrochemical sensor and comprises a working electrode, a counter electrode and a reference electrode; the working electrode comprises a ZIF-8 modified carbon electrode, and the electrode is prepared by coating a flexible substrate containing a carbon electrode with turbid liquid containing a ZIF-8 composite porous sensitive material and then drying. The ZIF-8 composite porous sensitive material is prepared by in-situ synthesis on a polyvinyl chloride material containing hydroxyl or carboxyl through a one-step method. When the sensor is used for ion detection, the anti-interference performance is high, the sensitivity is high, the ion selectivity is high, and the concentration of ions such as K < + >, Na < + > and Cl <-> in urine can be monitored for a long time under soaking. When the catheter loaded with the sensor is used for urine drainage of a patient, ions in urine can be detected in real time, and the sensor has lasting antibacterial performance.

This invention relates to a rapid, automatic response urine drainage device and a dedicated drainage material. The leak-proof outer shell 20 of the dedicated drainage material is equipped with an automatic trigger switch that automatically senses the patient's urination status and quickly initiates negative pressure suction. Upon completion of urination, the automatic trigger switch disconnects, and the urine drainage device 10 returns to standby or sleep mode. This technical solution not only results in lower-cost and more widely available nursing consumables, but also offers high sensitivity in urination status monitoring with an extremely low probability of distortion or false triggering. The fast negative pressure response time avoids urine leakage problems caused by delayed urine sensing or delayed negative pressure activation after urination.
