Automatic guarding detection device for falling of medical catheter

The utility model discloses an automatic guarding detection device for falling of a medical catheter, and relates to the technical field of medical instruments. The device comprises a sensing detection module which is connected with a catheter and is used for detecting a sensing signal of the catheter at a set position; the sensing signals are compared with a preset catheter falling threshold value, when any sensing signal exceeds the preset catheter falling threshold value, it is judged that the catheter falls off, and an alarm signal is output; the preset catheter falling threshold value is a change limit value of a sensing signal when the catheter is at a set position; the alarm module is connected with the sensing detection module and is used for carrying out sound-light alarm according to the alarm signal and transmitting a bed number corresponding to the alarm signal; and the background application module is connected with the alarm module and is used for transmitting the bed number and the alarm sensin
