The tube body 10 can be manufactured into various medical tubes such as drainage tubes, stomach tubes, indwelling tubes and the like according to the needs. The tube body 10 comprises an inner body section 11 and an outer body section 12; the section inserted into the patient is an internal section 11, and the section arranged outside the human body is an external section 12 for drainage, medicine filling or other purposes. It will be appreciated that the tubing body 10 may be made of a variety of materials that are known for medical tubing. The inner section 11 can be provided with a balloon and the like for positioning; the outer section 12 may be provided with branches such as a dosing tube. It will be appreciated that the conductive layer 20 is provided only on the outer wall of the outer body section 12, while the inner body section 11 is not provided with a conductive layer or any conductive material to prevent accidental injury to the patient or irritation to the patient's skin.

The conductive layer 20 is disposed on the outer wall of the outer section 12 so that when the patient grasps the outer wall of the tubular body 10, a shock current is generated to stimulate the patient and the patient is not required to continue to grasp the tubular body 10. The conductive layer 20 may be a conductive coating, which is coated on the outer wall of the pipe body 10 and is connected to the power source 30 through a wire 40. The length of the conductive layer 20 can be adjusted according to practical needs.

It can be appreciated that the conductive layer 20 may be disposed on the outer wall of the pipe body 10 in other manners, for example, the conductive layer 20 is an independent wrapping layer, and various wrapping layers with conductive properties such as a conductive metal layer, a conductive silica gel layer, a conductive rubber layer, a conductive fiber layer, etc. may be selected and wrapped on the outer wall of the pipe body 10 in various manners such as adhesion, winding or binding.

In this embodiment, the conductive layer 20 includes at least one positive electrode layer 21 and at least one negative electrode layer 22, which are coated on the outer wall of the pipe body 10 and are not conductive with each other. The positive electrode layer 21 and the negative electrode layer 22 are connected to the positive electrode and the negative electrode of the power supply 30, respectively, and a set gap 23 is provided between the positive electrode layer 21 and the negative electrode layer 22. The setting gaps 23 are equidistantly arranged, the distance is 0.1cm-2cm, and the setting gaps can be set to be of proper size according to actual needs; the setting gaps 23 may be non-equidistant.

As shown in fig. 2, the edges of the positive electrode layer 21 opposite to the negative electrode layer 22 are serrated, but other shapes are also possible, such as corrugated, straight, irregular, etc.

Further, the set gap 23 between the positive electrode layer 21 and the negative electrode layer 22 can be spirally arranged in the axial direction of the tube main body 10, so that any position of the hand of the patient holding the tube main body 10 can be contacted with the positive electrode layer 21 and the negative electrode layer 22, thereby conducting the positive electrode layer 21 and the negative electrode layer 22 to form a loop, the power supply 30 generates electric shock current output, and the purpose of stimulating the hand of the patient to loosen the hand of the patient is achieved.

As shown in fig. 3, the positive electrode layer 21 and the negative electrode layer 22 are provided in another manner, and the positive electrode layer 21 and the negative electrode layer 22 are provided in plural and alternately at intervals. The plurality of positive electrode layers 21 are connected in parallel to the positive electrode of the power supply 30, and the plurality of negative electrode layers 22 are connected in parallel to the negative electrode of the power supply 30. The positive electrode layer 21 and the negative electrode layer 22 may be disposed on the outer wall of the pipe body 10 in parallel with the axial direction of the pipe body 10, or may be disposed on the outer wall of the pipe body 10 in a spiral shape.

Through setting up a plurality of positive pole layers 21 and negative pole layer 22 interval in turn, when the patient held tubular product main part 10, can guarantee that the patient's hand contacted a positive pole layer 21 and a negative pole layer 22 at least to form a return circuit, power 30 produced electric shock current output, played the purpose that stimulates the patient's hand, and reached letting the patient loosen the hand.

The power supply 30 is connected to the conductive layer 20 by 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 through wires 40, respectively. The power supply 30 may be provided in the housing 31 separately from the pipe body 10. A clasp may be provided on the housing 31 to secure the power supply 30 in place, such as on a patient's clothing, bed edge, table edge, or other equipment.

Further, the active anti-pull medical tubing may also include an alarm device for signaling an alarm when the tubing body 10 is pulled out. The alarm device includes a housing 31, an alarm module mounted in the housing 31, and a connection 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 an acoustic alarm module, an optical alarm module and a vibration alarm module, and prompts a user in an acoustic, optical, vibration and other modes, so that the pipe main body 10 is pulled out or pulled to a certain position.

Further, the casing 31 may be further provided with a switch button 32, a display 33, etc., and the power supply 30 may be turned on and the alarm module may be turned on by the switch button 32. The display 33 may display power, operating status, alarm display, etc.

In this embodiment, the first end of the connecting wire 40 is connected to the conductive layer 20, and the second end of the connecting wire 40 is detachably connected to the alarm module, and when the second end is disconnected from the alarm module, the alarm module is triggered to emit an alarm signal.

The wire 40 may be detachably connected to the housing 31 of the power source 30, for example, one end of the wire 40 is electrically connected to the housing 31 through a magnetic terminal. Specifically, the housing 31 is provided with first terminals connected to the positive and negative electrodes of the power supply 30, respectively, and one end of the connecting wire 40 is provided with a second terminal that mates with the first terminal. The first terminal and the second terminal may be made of magnetic materials, and may be attracted to each other, so that the power source 30 is connected to the conductive layer 20 through the first terminal, the second terminal and the connection wire 40 to supply power to the conductive layer 20.

When the active anti-pulling medical catheter is used, the in-body section 11 of the tubular main body 10 is inserted into the corresponding part of the human body, the in-body section 12 is exposed outside the human body, and the connection of corresponding instruments such as a drainage bag, a medicine adding device and the like is completed.

Then the second terminal on the connecting wire 40 is attracted with the first terminal on the shell 31, the power supply 30 is turned on, the conductive layer 20 is powered by the power supply 30, and meanwhile, the alarm module is in a standby state. At this time, since the set gap 23 is provided between the positive electrode layer 21 and the negative electrode layer 22 of the conductive layer 20, the power supply 30 cannot form a loop, no electric shock current is generated between the positive electrode layer 21 and the negative electrode layer 22, and the conductive layer 20 is in an off state.

When a patient or other person mismanipulates the tube body 10, the person may grasp the outer wall of the tube body 10, i.e., the conductive layer 20 is grasped. 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, the power supply 30 outputs electric shock current to the conductive layer 20, thereby generating electric shock to the hand holding the pipe body 10, so that the user can feel painful and give up to continue holding the pipe body 10, thereby avoiding the risk of further pulling out the pipe body 10, and playing the active anti-pulling role.

It will be appreciated that the shock current output by the power supply 30 is within a safe range that is acceptable to the human body. The power supply 30 may be a rechargeable battery, a variable-voltage mains supply 30, or the like.

In other embodiments, the active anti-pull medical tubing may further comprise a pull out monitoring device for monitoring whether the tubing body 10 is being held, relative to the embodiments described above. When the pipe body 10 is monitored to be held, the power supply 30 is controlled to output electric shock current, so that the hand of a user is stimulated, the user releases the holding of the pipe body 10, the risk of further pulling out the pipe body 10 is avoided, and an active pulling-preventing effect is achieved.

The tube drawing monitoring device comprises one or more of a pressure sensor, an infrared sensor and an acceleration sensor which are arranged on the tube main body 10. The pressure sensor may be a soft film pressure sensor, wrapped on the outer wall of the pipe 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 sensors may be tube-type infrared sensors, which are respectively installed at both ends of the outer section 12 of the tube main body 10. When the pipe body 10 is held, an interrupt signal is generated to the tubular infrared sensor and output to the power supply 30, and the power supply 30 is controlled to output a shock current.

The acceleration sensor can be arranged at any position of the outer section 12 of the pipe main body 10, and when the pipe main body 10 is moved, the acceleration sensor can monitor displacement, movement track and the like of the pipe 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 may be implemented by various sensors, as long as the tube main body 10 is held, and 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 tubing may further include an ultra-slip coating layer disposed on the conductive layer 20 near the inner section 11 of the tubing body 10, which may create a slippery effect when the patient holds the tubing body 10, thereby making it more difficult to hold the tubing body 10 and better preventing the tubing body 10 from being pulled out.
