[0038] Furthermore, after the rotation direction of the output shaft of the driving motor 210 is reversed, the pulley 281 fixed on the outside of the transmission shaft 240 rotates, and through the transmission belt 282, the pulley 281 fixed on the outside of the center rod of the outer ring 272 is driven to rotate together with the outer ring 272, and after the multiple pawls 274 on the inner side of the outer ring 272 collide with the ratchet 273 of the rotating rod 271, the rotating rod 271 is driven to rotate as a whole.

[0039] In this embodiment, Figure 9-10 As shown, the tube moving device 400 includes two symmetrically arranged fixed frames 410, a fixed tooth plate 420 arranged on the outer side wall of the end of the fixed frame 410, a first screw rod 430 arranged inside the fixed frame 410, a worm gear 440 arranged at the bottom end of the first screw rod 430, and a moving part 450 arranged between the two fixed frames 410; Specifically, the moving part 450 includes a moving horizontal plate 451 , a fixed clamping block 452 provided in a slot inside the moving horizontal plate 451 , a moving clamping block 454 symmetrically provided on the fixed clamping block 452 , and a second screw rod 453 driving the moving clamping block 454 to move.

[0041] Furthermore, the two ends of the movable horizontal plate 451 are slidably connected to the inside of the fixed frames 410 on both sides, the movable horizontal plate 451 is threadedly connected to the first screw rod 430, and a plurality of regularly distributed placement grooves are opened inside the movable horizontal plate 451, and the fixed clamp block 452 is clamped and fixed on the groove wall of the placement groove inside the movable horizontal plate 451.

[0042] Furthermore, the second screw rod 453 is rotatably connected to the inside of the movable horizontal plate 451, the movable clamping block 454 is slidably connected to the groove wall of the placement groove inside the movable horizontal plate 451 and is threadedly connected to the second screw rod 453, and the end position of the second screw rod 453 is clamped and fixed with a rod end gear 455 that meshes with the fixed tooth plate 420.

[0043] Furthermore, when the worm 250 rotates, it conflicts with the worm wheel 440, and drives the first screw rod 430 to rotate, thereby driving the movable cross plate 451 to move. When the movable cross plate 451 moves downward between the two fixed frames 410, the rod end gear 455 conflicts with the fixed gear plate 420, and drives the second screw rod 453 to rotate, thereby driving the movable clamp block 454 to move in the placement groove inside the movable cross plate 451, and cooperates with the fixed clamp block 452 to clamp and fix the three pipes in the desktop gastric lavage machine 300, and continue to move the bottom ends of the three pipes toward the inside of the liquid storage tank 520.

[0044] In this embodiment, Fig.11 As shown, the liquid storage part 500 includes a moving platform 510 slidably connected to the top surface of the moving frame plate 110, a group of liquid storage boxes 520 placed parallel to the top surface of the moving platform 510, and a partition plate 530 arranged on the inner box wall of a liquid storage box 520, and the protrusion at the bottom end of the moving platform 510 is sleeved on the outer side of the rotating rod 271; Furthermore, when the rotating rod 271 rotates, the moving platform 510 is displaced, thereby driving the two liquid storage boxes 520 to move below the moving horizontal plate 451 .

[0045] Finally, it should be noted that the drive motor 210 and the desktop gastric lavage machine 300 involved in the present invention are universal standard parts or parts known to those skilled in the art, and their structures and principles are known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of the device, the drive motor 210 and the desktop gastric lavage machine 300 are connected to an external power supply through a wire. The specific connection means should refer to the working principle of the present invention. The electrical connections between the electrical components are completed in a sequential working order, and the detailed connection means are all well-known technologies in the art.

[0046] When the pressurized gastric lavage device for gastroenterology of the present invention is used, the medical staff first passes the three pipes in the table-top gastric lavage machine 300 through the three placement grooves of the movable horizontal plate 451, and puts the sewage pipe among the three pipes into one side of the partition plate 530 in one of the liquid storage boxes 520, and puts the liquid inlet pipe and the stomach tube into the other side of the partition plate 530 in the liquid storage box 520; Next, the medical staff pours disinfectant chlorine water into the other side of the partition 530 in the liquid storage box 520 and activates the cleaning button in the table-top gastric lavage machine 300; Then, the driving motor 210 is started, and drives the rotating shaft 220 and the two main bevel gears 230 to rotate. After the main bevel gears 230 contact the auxiliary bevel gears 260, the transmission shaft 240 and the worm 250 are driven to rotate. After the worm 250 rotates, it contacts the worm wheel 440 in the moving part 450, and drives the worm wheel 440 and the second screw rod 453 to rotate, so that the moving horizontal plate 451 moves downward; At this time, the rod end gear 455 contacts the fixed tooth plate 420, driving the second screw rod 453 to rotate, thereby driving the movable clamping block 454 to move in the placement groove inside the movable horizontal plate 451, and cooperate with the fixed clamping block 452 to clamp and fix the three pipes; Then, the movable horizontal plate 451 continues to carry the bottom ends of the three pipes into the liquid storage box 520, and after the impurities of the table-type gastric lavage machine 300 in the sewage pipe are completely discharged from the sewage pipe, the rotation direction of the output shaft of the driving motor 210 is controlled to reverse; At this time, while the movable horizontal plate 451 moves upward with the three pipes of the table-type gastric lavage machine 300, the power of the driving shaft 240 is transmitted to the outer ring 272 through the transmission part 280. After the plurality of ratchets 274 of the outer ring 272 abut against the ratchet 273 of the rotating rod 271, the rotating rod 271 is driven to rotate as a whole, thereby causing the movable platform 510 to move, and causing the other liquid storage box 520 to move to the right below the movable horizontal plate 451. Afterwards, the rotation direction of the output shaft of the driving motor 210 is changed again. After the desktop gastric lavage machine 300 and the three pipes are fully cleaned, the position of the movable horizontal plate 451 is restored by the driving motor 210. Then, the medical staff can separate and store the three pipes from the desktop gastric lavage machine 300.
