Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figure 1 As shown, a bowel cleaning and care device for preoperative colonoscopy in gastroenterology includes a workbench 1, a control host 11 is installed inside the workbench 1, and the control host 11 is connected to a display control panel 12. The display control panel 12 is installed on the surface of the workbench 1 and is used to control and set parameters of various components. Existing equipment is used.

[0021] In this embodiment, to achieve the supply of cleaning fluid and the removal of waste fluid, the workbench 1 is equipped with a booster water pump 13, a liquid extraction pump 14, and a cleaning fluid tank 15. It also features a coaxially mounted internal supply pipe 2 and external extraction pipe 3, as shown below. Figure 2 As shown, the inner liquid supply pipe 2 and the outer liquid extraction pipe 3 are connected to the booster pump 13 and the extraction pump 14, respectively. A spray ring 21 is provided at the top of the inner liquid supply pipe 2. The bottom of the spray ring 21 is threaded to the top of the outer liquid extraction pipe 3 and reinforced with screws to prevent rotation of the spray ring 21 during operation. Several spray nozzles 22 are provided on the circumferential side of the spray ring 21. The spray ring 21 is connected to the inner liquid supply pipe 2 to achieve multi-angle spraying of cleaning liquid, improving cleaning efficiency.

[0022] Since waste in the intestines exists in the following states in sequence: liquid, semi-fluid, porridge-like, semi-porridge-like, semi-solid, and solid, cleaning the waste (semi-solid to solid) after descending colon is time-consuming. Therefore, a scraping mechanism 4 is installed to first clean the waste after descending colon by scraping. Figures 3-4 As shown, the scraping mechanism 4 is located at the bottom of the spray ring 21. Figure 2 The scraping mechanism 4 is in an undeployed state. The scraping mechanism 4 includes several rotating shafts 41 circumferentially distributed at the bottom of the spray ring 21. A first drive gear 42 is provided on the rotating shaft 41. A first drive gear ring 43 is rotatably connected to the bottom of the spray ring 21. Several first drive gears 42 mesh with the inner side of the first drive gear ring 43. One of the rotating shafts 41 is connected to an deployment drive motor 44 (using a micro motor). A scraping assembly is connected to the top of the rotating shaft 41. The scraping assembly includes an arc-shaped support 45 and a flexible baffle 46. The flexible baffle 46 has a sheet-like structure and is made of silicone or gauze. One end of the flexible baffle 46 is connected to... The arc-shaped support 45 is fixedly connected, and the other end of the flexible baffle 46 is fixed to the bottom of the spray ring 21. One end of the arc-shaped support 45 is fixed to the top of the rotating shaft 41. The arc-shaped support 45 is made of silicone material with a certain hardness to avoid damage to the intestine. The other end of the arc-shaped support 45 is equipped with a first flexible pressure sensor. The bottom of the spray ring 21 is connected to a protective end cap 47. Several first flexible pressure sensors and unfolding drive motors 44 are electrically connected to the control host 11. By controlling the forward and reverse rotation of the unfolding drive motors 44, the unfolding degree of each arc-shaped support 45 and flexible baffle 46 can be realized to adapt to intestines of different sizes.

[0023] The external suction pipe 3 has several suction ports 32 on its circumferential side for the suction section 31. To prevent the suction ports 32 from becoming clogged, a rotating anti-clogging sleeve 5 is also provided. Figures 5-6As shown, the rotating anti-clogging sleeve 5 is rotatably connected to the spray ring 21. The rotating anti-clogging sleeve 5 is disposed between the inner supply pipe 2 and the outer suction pipe 3 and is positioned opposite to the suction part 31 of the outer suction pipe 3. The rotating anti-clogging sleeve 5 includes a rotating drive motor 51 disposed inside the protective end cover 47. The output shaft of the rotating drive motor 51 passes through the protective end cover 47 and is connected to a second drive gear 52. The inner side of the rotating anti-clogging sleeve 5 is rotatably mounted on the outer side of the inner supply pipe 2 via a bearing. A second drive gear ring 53 is disposed on the outer side of the rotating anti-clogging sleeve 5. The outer side of the gear ring meshes with the second drive gear 52. The rotary drive motor 51 is electrically connected to the control host 11. The circumferential side of the rotary anti-blocking sleeve 5 is provided with an elastic plug 54. The elastic plug 54 includes a limiting sleeve 541. A plug 542 is provided at the bottom of the inner side of the limiting sleeve 541. A limiting ring 543 is provided at the top of the inner side of the limiting sleeve 541. One end of the adjusting spring 544 is in contact with the plug 542. The other end of the adjusting spring 544 is in contact with the plug ball 545. The plug ball 545 is in contact with the limiting ring 543.

[0024] By controlling the forward and reverse rotation of the rotary drive motor 51, the elastic plug 54 and the suction port 32 are positioned opposite each other, pushing out the waste blocking the suction port 32 and avoiding a large amount of blockage in the suction port 32. At the same time, the suction port 32 can also be opened and closed.

[0025] An external suction tube 3 is fitted with a sealing and discharge mechanism 6, used to seal the anus and facilitate the discharge of solid waste. For example... Figure 7 , Figure 8 as well as Figure 9 As shown, the draining mechanism includes a hollow mounting ring 61 sleeved on the outer suction pipe 3. One side of the hollow mounting ring 61 is open, and the other side is closed. A conical water bladder ring 62 is provided on the circumference of the hollow mounting ring 61. Several second flexible pressure sensors are provided on the outer side of the conical water bladder ring 62. A drain connector 63 is provided on the circumference of the hollow mounting ring 61. The drain connector 63 is connected to a flexible drain pipe 64. The conical water bladder ring 62 is connected to a regulating water pump 66 through a regulating pipe 65. The regulating water pump 66 is connected to a warm water tank 67. The regulating water pump 66 and the second flexible pressure sensors are both electrically connected to the control host 11.

[0026] To expedite the discharge of solid waste, a pushing component 69 is provided. The pushing component 69 is fixed to a fixed bracket 68 on a hollow mounting ring 61. A limit clamp 6910 is also provided on the fixed bracket 68, and a flexible discharge pipe 64 is positioned within the limit clamp 6910 to prevent it from moving erratically. The pushing component 69 includes two symmetrically arranged pushing cams 691, which are rotatably mounted on the fixed bracket 68. A driven sprocket 692 is mounted on the shaft 41 of one pushing cam 691, and a reversing gear 693 is mounted on the shaft 41 of the other pushing cam 691. The third drive gear 694 is rotatably mounted on the fixed bracket 68. The drive sprocket 695 is mounted on the shaft 41 of the third drive gear 694. The drive sprocket 695 is connected to the output shaft of the push drive motor 697. The drive sprocket 695 is connected to the driven sprocket 692 by a chain. A protective cover 696 is also provided on the outside of the fixed bracket 68. The push drive motor 697 is installed inside the protective cover 696 and is electrically connected to the control host 11. By driving the push drive motor 697, the two push cams 691 are rotated, which squeezes the waste to the next stage and speeds up the fixed discharge.

[0027] like Figure 10 As shown, the inlet pipe of the booster pump 13 is connected to the cleaning liquid tank 15, and a water level sensor is installed inside the cleaning liquid tank 15. The outlet pipe of the booster pump 13 is connected to the inner supply pipe 2, and a flow sensor is installed in the inner supply pipe 2. The booster pump 13, the water level sensor, and the flow sensor are all electrically connected to the control host 11. The drain pipe and flexible discharge pipe 64 of the liquid pump 14 are both connected to the waste liquid tank 16 inside the workbench 1. The inlet pipe of the liquid pump 14 is connected to the outer liquid pumping pipe 3. The flow sensor installed on the drain pipe and the liquid pump 14 are both electrically connected to the control host 11.

[0028] The specific usage process is as follows: First, when the inner supply tube 2 and the outer suction tube 3 are inserted through the solid waste into the tail of the descending colon, (the approximate position of the spray ring 21 is estimated based on data from different individuals) the unfolding drive motor 44 is activated to rotate forward and unfold several flexible baffles 46 until the pressure of the first flexible pressure sensor reaches the maximum set value. Since the intestine is peristaltic, when the pressure of the first flexible pressure sensor is less than the minimum set value, the unfolding drive motor 44 is activated to rotate forward. When the pressure of the first flexible pressure sensor is greater than or equal to the maximum set value, the unfolding drive motor 44 is activated to rotate in reverse, so that the pressure of the first flexible pressure sensor is within the set range. The inner supply tube 2 and the outer suction tube 3 are slowly pulled out. Under the action of multiple flexible baffles 46, most of the solid waste moves into the hollow mounting ring 61 and is discharged through the flexible discharge tube 64.

[0029] Then, the unfolding drive motor 44 is started to rotate in the opposite direction, rotating the arc-shaped support 45 and the flexible baffle 46 to the bottom of the spray ring 21 and then stopping. The rotation drive motor 51 is started, causing the rotating anti-blocking sleeve 5 to rotate, so that the elastic block 54 is not opposite to the suction port 32. That is, after the suction port 32 is opened, the rotation drive motor 51 stops rotating. The inner supply pipe 2 and the outer suction pipe 3 slowly advance, and the booster water pump 13 and the suction pump 14 are started at the same time to perform the first flushing of the intestine, while rinsing and suctioning the waste liquid. After reaching the end of the intestine, the inner supply pipe 2 and the outer suction pipe 3 are slowly pulled out for the second flushing.

[0030] During the rinsing process, when the flow sensor on the drain pipe is lower than the set value, it is determined that the suction port 32 is blocked. The rotary drive motor 51 is started, so that the rotating anti-blocking sleeve 5 rotates and stops after the elastic plug 54 passes the suction port 32, so that the elastic plug 54 is not opposite to the suction port 32. If the flow sensor on the drain pipe recovers, the rinsing tank continues. If the flow sensor on the drain pipe remains below the set range, the operation is stopped, the inner liquid supply pipe 2 and the outer liquid extraction pipe 3 are pulled out to check the specific situation, and the operation is resumed after the fault is eliminated.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
