The positioning plate can provide effective guidance for the placement position of the centralizing box 2, so that the connection position of the centralizing box 2 and the blocking cover 3 is more accurate;

[0035] More specifically, the concentration box 2 is made of a transparent material, and through the material characteristics of the concentration box 2, the concentration status of the concentration box 2 can be intuitively fed back;

[0036] In this embodiment, the top edge of the bearing bottom plate 1 and the bottom edge of the blocking cover 3 are fixedly connected with sealing strips.

[0046] Here, both ends of the liquid storage tank 26 are provided with liquid level feedback windows, and transparent plates are fixedly connected to the inside of the liquid level feedback windows. The two liquid level feedback windows are respectively connected to the lubricating oil storage chamber 28 and the cleaning liquid storage chamber 29. By setting the liquid level feedback windows, the remaining amount of the lubricating oil storage chamber 28 and the cleaning liquid storage chamber 29 can be intuitively fed back to remind personnel to replenish them in time. In this embodiment, two liquid adding pipes are also fixedly connected to the top of the liquid storage tank 26. The two liquid adding pipes are respectively connected to the lubricating oil storage chamber 28 and the cleaning liquid storage chamber 29, and the top ends of the liquid adding pipes are provided with sealing plugs.

[0047] The liquid supply assembly 9 also includes a blocking shaft A34, a blocking shaft B35, a blocking piece 36, a transmission plate 37 and a matching plate 38. The tops of both ends of the three-way pipe 32 are rotatably connected to the blocking shaft A34 and the blocking shaft B35, and the ends of the blocking shaft A34 and the blocking shaft B35 located inside the three-way pipe 32 are fixedly connected to the blocking piece 36, and the two blocking pieces 36 are perpendicular to each other. The outer side of the blocking shaft B35 is fixedly connected to the transmission plate 37, and the top of the blocking shaft A34 is fixedly connected to the matching plate 38, and the matching plate 38 and the transmission plate 37 are perpendicular to each other. The end of the plate 37 away from the blocking shaft B35 is rotatably connected to the linkage plate 39, and the end of the linkage plate 39 away from the transmission plate 37 is also rotatably connected to the matching plate 38. The top of the blocking shaft B35 is fixedly connected to the limit plate 40, and one end of the limit plate 40 is vertically slidably connected to the limit column 41. The top of the limit column 41 is fixedly connected to the limit piece 42, and the bottom end of the limit piece 42 is fixedly connected to the limit plate 40. A coil spring 43 is fixedly connected between the limit plate 40 and the bottom end of the limit piece 42.

[0048] Furthermore, a sealing ring is fixedly connected to the outer side of the blocking piece 36, and a transition fit is formed between the sealing ring and the inner wall of the tee pipe 32. By setting the sealing ring, the connection gap between the blocking piece 36 and the tee pipe 32 can be blocked to prevent uncontrolled leakage of the medium.

[0049] In more detail, a plurality of locking holes are provided at the top of the locking disk 44, and the bottom end of the limiting column 41 is snap-connected to the inside of the locking hole. By utilizing the setting of the locking hole, when the limiting column 41 is connected to the locking disk 44, it can be snapped into the inside of the locking hole, so that the limiting column 41 is stably limited on the locking disk 44.

[0050] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0051] Working principle: first, pull the limit plate 42 upward to move the limit column 41 out of the locking disk 44 and stretch the coil spring 43, then pull the limit plate 40. Since the limit plate 40 is supported by the blocking shaft rod B35, it can drive the blocking shaft rod B35 to rotate. In conjunction with the connection between the blocking shaft rod B35 and the transmission plate 37, during the rotation of the blocking shaft rod B35, the movable plate 38 can be pushed through the linkage plate 39 to drive the movable plate 38 to drive the blocking shaft rod A34 to rotate, so that the two blocking plates 36 rotate at the same time, and the blocking plate 36 on the blocking shaft rod A34 is used to close one end of the three-way pipe 32, and the other blocking plate 36 releases the blockage of the other end of the three-way pipe 32, and then releases the pull on the limit plate 42, so as to drive the limit column 41 to re-enter the locking disk 44 with the help of the rebound of the coil spring 43, thereby locking the position of the blocking plate 36;

[0052] Then, the external pump 30 is started to extract the lubricating oil in the lubricating oil storage chamber 28 through one of the outlet pipes 33, and is injected into the shunt pipe 15 through the three-way pipe 32 and the liquid supply pipe 31, and then is introduced into the application pipe 13 through the delivery pipe 16, and finally penetrates through the through hole 14. Then, the drainage tube body 10 is inserted into the patient's intestine through the patient's anus. During the insertion process, the patient's discomfort can be alleviated by the continuous supply of lubricating oil. The feces in the intestine can be drained through the drainage tube body 10 and introduced into the concentration box 2 through the transmission pipe 5 for concentration. The negative pressure pump 7 can be started to generate negative pressure inside the concentration box 2 through the guide pipe 8, thereby accelerating the drainage speed of the drainage tube body 10.

[0053] When it is necessary to flush the patient's intestine, first pull the limit column 41 and drive the limit plate 40 to rotate, so that the blocking piece 36 located on one side of the lubricating oil storage chamber 28 blocks the other end of the three-way pipe 32, and the blocking piece 36 on the blocking shaft A34 releases the blocking of one end of the three-way pipe 32, and then start the external pump 30 to extract the liquid in the cleaning liquid storage chamber 29 through the outlet pipe 33, and inject it into the shunt pipe 15 through the liquid supply pipe 31, and finally spray it out through the through hole 14, so that the patient's intestine is flushed;

[0054] After drainage, the transmission shaft 23 is rotated to prompt the transmission worm 24 to move the matching worm gear 25, and the eccentric plate 20 can be driven to rotate through the central shaft 19. Under the connection between the eccentric plate 20 and the linkage column 22, the linkage column 22 can follow the rotation of the eccentric plate 20 to drive the blocking cover 3 to move vertically under the limit of the linear guide 18 until the blocking cover 3 is away from the centralizing box 2, and then the centralizing box 2 is removed from the supporting base plate 1, and the feces inside the centralizing box 2 can be processed. After processing, the container is disinfected and cleaned, and then it is placed on the supporting base plate 1 again, and the centralizing box 2 is fixed again by the blocking cover 3, so that the centralizing box 2 can be reused.
