The power source 30 is connected to the conductive layer 20 through a wire 40 to supply power to the conductive layer 20. The positive and negative electrodes of the power supply 30 may be connected to the positive and

negative electrode layers

21 and 22 of the conductive layer 20, respectively, through wires 40. The power source 30 may be disposed in the housing 31, separately from the tube body 10.

Further, the active anti-pull medical tubing may further comprise an alarm device for emitting an alarm signal when the tubing main body 10 is pulled out. The alarm device includes a housing 31, an alarm module mounted in the housing 31, and a connecting wire 40 connected to the conductive layer 20. The power supply 30 and alarm module may be mounted in the same housing 31, with the conductive layer 20 being powered by the connecting wires 40. Of course, the power supply 30 and alarm module may also be separated in different housings.

The alarm module can adopt one or more of a sound alarm module, a light alarm module and a vibration alarm module, and prompts a user in the modes of sound, light, vibration and the like, so that the pipe main body 10 is pulled out or pulled to a certain position.

When a patient or other person mishandles the tube main body 10, the outer wall of the tube main body 10 is held by a hand, that is, the conductive layer 20 is held. At this time, since the hand of the person is a conductor, the positive electrode layer 21 and the negative electrode layer 22 are connected to form a loop with the power supply 30, and the power supply 30 outputs an electric shock current to the conductive layer 20, so that an electric shock is generated to the hand holding the tube main body 10, and the holder gives up holding the tube main body 10 due to the pain, thereby avoiding the risk of further pulling out the tube main body 10, and playing a role of actively preventing pulling out.

It will be appreciated that the shock current output by the power supply 30 is within a safe range of shock currents that can be tolerated by the human body. The power supply 30 may be a rechargeable battery, a variable voltage mains power supply 30, or other various power supplies 30.

In other embodiments, relative to the above embodiments, the active withdrawal prevention medical tubing may further include a withdrawal monitoring device for monitoring whether the tubing main body 10 is held. When the situation that the pipe main body 10 is held is monitored, the power supply 30 is controlled to output electric shock current, so that the hand of a holder is stimulated, the holder releases the holding of the pipe main body 10, the risk that the pipe main body 10 is further pulled out is avoided, and the active pulling-out prevention effect is achieved.

The pipe drawing monitoring device comprises one or more of a pressure sensor, an infrared sensor and an acceleration sensor which are arranged on the pipe body 10. The pressure sensor may be a flexible film pressure sensor, and is wrapped on the outer wall of the tube main body 10, and transmits a sensing signal to the power supply 30, and when the sensed pressure signal exceeds a set value, the power supply 30 is controlled to output an electric shock current.

The infrared sensor may be a double-pipe infrared sensor, and is respectively installed at two ends of the outer section 12 of the pipe body 10. When the tube main body 10 is held, an interrupt signal is generated for the tube type infrared sensor and is output to the power supply 30, and the power supply 30 is controlled to output an electric shock current.

The acceleration sensor can be arranged at any position of the outer section 12 of the tube main body 10, and when the tube main body 10 is moved, the acceleration sensor can monitor the displacement, the motion track and the like of the tube main body 10, so that the power supply 30 is controlled to output electric shock current, and the active anti-pulling effect is realized.

Of course, the tube drawing monitoring device can also be realized by various sensors, as long as when the tube main body 10 is held, the control signal is generated to control the power supply 30 to output the electric shock current.

Further, in some embodiments, the active anti-pulling medical tube may further include an ultra-smooth coating layer, which is disposed at the inner section 11 of the conductive layer 20 close to the tube main body 10, and when a patient holds the tube main body 10, the tube main body 10 is more difficult to hold, and the tube main body 10 is better prevented from being held and pulled out.
