Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] Reference Figure 1-Figure 5 , the utility model provides an embodiment: a new bidirectional bioelectric signal conduction device for the intestine, including a pipeline portion 1, a plurality of inflatable balloons 2 are embedded in the surface of the pipeline portion 1, a plurality of bidirectional guiding electrodes 3 are connected to the surface of the inflatable balloons 2, one end of the pipeline portion 1 is detachably connected to a detachable power supply 4 with a storage chip, the inner wall of the pipeline portion 1 is provided with an inflation connection channel 6 connected to the plurality of inflatable balloons 2, the end of the pipeline portion 1 away from the detachable power supply 4 is connected to an insertion end 5, a plurality of micro liquid outlet holes 501 are opened on the surface of the insertion end 5, the inner wall of the pipeline portion 1 is provided with a liquid inlet channel 8, one end of the liquid inlet channel 8 is connected to the insertion end 5, an inflation port 10 and a liquid inlet 7 are provided on the surface of the pipeline portion 1, the inflation port 10 is connected to the inflation connection channel 6, the liquid inlet 7 is connected to the liquid inlet channel 8, and the inflation port 10 and the liquid inlet 7 are respectively connected to the inflation and liquid injection component 9 through pipelines.

[0027] The inflation and liquid injection component 9 includes an inflation chamber 901 and a lubricating liquid chamber 902. A piston 903 is provided inside the inflation chamber 901 and the lubricating liquid chamber 902. A piston rod 904 is fixed to one end of the piston 903. The piston rod 904 is L-shaped. Two strip openings 906 are provided on the outer surface of the inflation and liquid injection component 9. One end of the piston rod 904 extends to the outside through the strip opening 906 and is fixed with a positioning component 905.

[0028] The positioning assembly 905 includes a fixed shell 9052, and the internal rotation of the fixed shell 9052 is connected to a pressure plate 9051, a spring 9053 is connected between one end of the pressure plate 9051 and the fixed shell 9052, and the other end of the pressure plate 9051 is connected to a card block. When one end of the pressure plate 9051 is pressed, the end with the card block will tilt up under the rotation and compression of the spring 9053, thereby realizing the separation of the card block and the positioning groove 907.

[0029] A plurality of positioning grooves 907 are provided on the surface of the strip-shaped opening 906. The card block engages with or separates from any positioning groove 907 to achieve positioning.

[0030] Working principle: When in use, first press the positioning component 905 on one side of the lubricating liquid chamber 902, lift one end of the pressure plate 9051, separate the block and the positioning groove 907, and then push the positioning component 905 to move the piston 903 downward, so that the lubricating liquid flows out from the insertion end 5, which can lubricate the anus and smoothly insert the pipe part 1 into the intestine. Then, press the positioning component 905 on one side of the inflation chamber 901 to push the piston 903 to inflate the inflation balloon 2. When it is inflated to a certain degree, release it. Open the pressure plate 9051. Under the action of the spring 9053, the block of the pressure plate 9051 re-engages with the positioning groove 907 to achieve positioning. At this time, after the inflatable balloon 2 is inflated, the pipeline part 1 is fixed in the intestine, and the bidirectional guiding electrode 3 is fully in close contact with the intestinal wall, which is conducive to draining excrement from the intestine to the body. At the same time, after the bidirectional guiding electrode 3 is in close contact with the intestinal wall, it can guide the current to stimulate the intestinal wall, and then collect the bioelectric signals emitted by the intestinal wall, and transmit the collected bioelectric signals to the storage chip.
