Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of gastrointestinal cleaning equipment, and particularly relates to a circulating gastrointestinal cleaning device. BACKGROUND

[0002] The gastrointestinal tract generally refers to the stomach and small intestine, large intestine part of the digestive system. And the stomach and small intestine are the core of nutrient absorption. Almost all the nutrients needed by the human body need to pass through the gastrointestinal tract. The gastrointestinal tract becomes the most important organ of digestion.

[0003] When the human body has an accident, such as gastrointestinal poisoning, the gastrointestinal tract needs to be cleaned by a gastrointestinal cleaning device. When cleaning the gastrointestinal tract, clean water or liquid medicine is usually injected into the gastrointestinal tract, and then the internal and external substances are replaced by extracting from the gastrointestinal tract. After repeated multiple times, the purpose of removing toxins and toxic substances in the gastrointestinal tract is achieved.

[0004] Because the contents of the gastrointestinal tract are various and their sizes are different, the existing gastrointestinal cleaning equipment has a separation function when recovering the cleaning liquid, but after long-term use, the filtering function is reduced. At this time, the existing equipment needs to manually replace the filter plate and other filtering structures. SUMMARY

[0005] The purpose of the present application is to provide a circulating gastrointestinal cleaning device to solve the above-mentioned problems existing in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

The second groove connects the first groove to the outside. The first groove and the second groove form a slot that fits the filter plate. The filter plate passes through the slot and the middle part of the filter plate merges with the first groove to form a filter area. The two ends of the filter plate pass through the second groove.

[0014] The middle channel has two opposite sides, one side is equipped with a filter plate replacement structure and the other side is equipped with a filter residue collection structure. Correspondingly, one end of the opposite ends of the filter frame is connected to the filter plate replacement structure and the other end is connected to the filter residue collection structure.

[0016] In one possible design, one of the opposite ends of the filter frame is configured as a rotating end, and the other end is configured as a lifting end connected to a first telescopic device. Accordingly, the rotating end is connected to the filter plate replacement structure, and the lifting end is connected to the filter residue collection structure.

[0017] Correspondingly, the connection between the middle channel and the rotating end is constructed as a flexible waterproof layer, the filter frame is rotatably set inside the flexible waterproof layer, and a third groove is provided on the flexible waterproof layer to connect the filter plate replacement structure.

[0018] In one possible design, the filter plate replacement structure includes a slide rail and a second telescopic device. Two slide rails are provided and arranged opposite each other, forming a filter plate slide. The upper end of the filter plate slide extends and connects to the top surface of the trolley, and the lower end of the filter plate slide abuts against the middle channel. The second telescopic device is located outside the filter plate slide and is used to push the filter plate. Correspondingly, the trolley is provided with a replacement port adapted to the upper slide.

[0019] In one possible design, when the filter plate replacement structure is used to replace the filter plate, the filter frame is tilted with the rotating end on top and the lifting end on the bottom.

When the filter holes on the filter plate become clogged and its filtration capacity decreases, the filter plate can be replaced via a filter plate replacement structure. The old filter plate enters the filter residue collection structure and is subsequently removed and cleaned along with the filter residue. A new filter plate is inserted into the slot to restore filtration capacity. Therefore, the circulating gastrointestinal cleansing device features an automatic filter plate replacement function, eliminating the need for manual replacement and reducing the workload of staff. Furthermore, the filter plate replacement structure enables rapid replacement, minimizing downtime and preventing delays in the gastrointestinal cleansing process. Attached Figure Description

[0033] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0034] Example:

[0035] like Figures 1-5 As shown, a circulating gastrointestinal cleansing device includes a trolley 100, a water tank 200, a drive unit 300, and a cleansing tube 400;

[0036] Water tank 200 includes clean water tank 201 and sewage tank 202, drive component 300 includes first drive component 301 and second drive component 302, and cleaning pipe 400 includes clean water pipe 401 and sewage pipe 402.

[0037] Both the clean water tank 201 and the wastewater tank 202 are located inside the trolley 100;

[0038] One end of the water purification pipe 401 is connected to the water purification tank 201, and the other end of the water purification pipe 401 extends to the outside of the trolley 100. The first driving component 301 is installed on the water purification pipe 401. Accordingly, the water purification tank 201, the first driving component 301 and the water purification pipe 401 form a water supply group.

[0039] One end of the sewage pipe 402 is connected to the sewage tank 202, and the other end of the sewage pipe 402 extends to the outside of the trolley 100. The second drive component 302 is installed on the sewage pipe 402. Accordingly, the sewage tank 202, the second drive component 302 and the sewage pipe 402 form a return water group.

[0040] Wastewater tank 202 is connected to wastewater pipe 402 via intermediate channel 101;

[0041] The intermediate channel 101 is provided with a filter frame 501 and a filter plate 502. The filter frame 501 is provided with a first groove 503. The filter frame 501 has two opposite ends, and each end is provided with a second groove 504. The second groove 504 connects the first groove 503 to the outside. The first groove 503 and the second groove 504 form a slot adapted to the filter plate 502. The filter plate 502 passes through the slot, and the middle part of the filter plate 502 overlaps with the first groove 503 to form a filter area. The two ends of the filter plate 502 pass through the second groove 504.

[0042] The intermediate channel 101 has two opposite sides, one side is provided with a filter plate replacement structure 600 and the other side is provided with a filter residue collection structure 700. Correspondingly, one of the opposite ends of the filter frame 501 is connected to the filter plate replacement structure 600 and the other side is connected to the filter residue collection structure 700. The intermediate channel 101 is provided with a slag outlet 102 that communicates with the filter residue collection structure 700.

[0043] In the described circulating gastrointestinal cleansing device, a filter frame 501 engages with a filter plate 502, creating a detachable connection. When the filter pores on the filter plate 502 become clogged and its filtration capacity decreases, the filter plate 502 is replaced via a filter plate replacement structure 600. The old filter plate 502 enters the filter residue collection structure 700, where it is subsequently removed and cleaned along with the filter residue. A new filter plate 502 is inserted into the slot to restore its filtration capacity. Therefore, the circulating gastrointestinal cleansing device features an automatic filter plate 502 replacement function, eliminating the need for manual replacement and reducing the workload of staff. Furthermore, the filter plate replacement structure 600 enables rapid replacement, minimizing downtime and preventing delays in the gastrointestinal cleansing process.

[0044] During operation, staff members push the trolley 100 to the patient, insert the outer end of the cleaning tube 400 into the patient's body, and activate the drive unit 300. Specifically, the first drive unit 301 is activated first to deliver the liquid in the clean water tank 201 into the patient's body through the clean water pipe 401. The liquid cleanses the patient's stomach and intestines, forming a mixture with the stomach and intestines contents. Then, the second drive unit 302 is activated to extract the mixture from the patient's body into the wastewater tank 202 through the wastewater pipe 402.

[0045] Based on this, the patient's gastrointestinal tract can be cleaned cyclically. Meanwhile, it is easy to understand that the clean water tank 201, wastewater tank 202, clean water pipe 401, wastewater pipe 402, first drive component 301, and second drive component 302 can each be any suitable commercially available model.

[0046] The mixed liquid flows out of the sewage pipe 402 and into the intermediate channel 101. As the mixture flows through the filter plate 502, separation occurs. The mixed liquid comprises a solution and a solute, with the portion of the solute larger than the filter pores of the filter plate 502 classified as large particles, and the portion of the solute smaller than the filter pores as small particles. The solution and small particles flow through the filter plate 502 and into the sewage tank 202, while the large particles are retained on the filter plate 502, thus achieving separation. The intermediate channel 101 is connected to the filter residue collection structure 700 through the sludge outlet 102. The filter residue collection structure 700 collects large particles to prevent them from affecting the filtration capacity of the filter plate 502.

[0047] After prolonged use, the filter pores of filter plate 502 will become clogged. As the clogging increases and large particles become trapped, the filtration efficiency of filter plate 502 will significantly decrease, and solutions and small particles may even enter the filter cake collection structure 700. In this case, filter plate 502 needs to be replaced to restore filtration efficiency. Activate the filter plate replacement structure 600, push the spare filter plate 502 into the intermediate channel 101 (i.e., insert the spare filter plate 502 into the slot), and push the old filter plate 502 out of the filter frame 501, thus replacing filter plate 502.

[0048] In this embodiment, the side wall of the first groove 503 and the outer side of the filter plate 502 abut against each other, and one of the side wall of the first groove 503 and the outer side of the filter plate 502 is provided with a protruding locking block 505, and the other is provided with an inner groove 506 adapted to the locking block 505. Correspondingly, the contact surfaces of the locking block 505 and the inner groove 506 are both constructed as arc surfaces.

[0049] Based on the above design, the locking block 505 is inserted into the inner groove 506 to increase the contact area between the first groove 503 and the filter plate 502. This also forms a stop and limit, improving the stability of the connection between the filter frame 501 and the filter plate 502, preventing disturbance of the filter plate 502, and thus avoiding large particles leaking into the wastewater tank 202, ensuring effective separation. Furthermore, considering that the filter plate 502 needs to be replaced, the contact surfaces of the locking block 505 and the inner groove 506 are both constructed as arc surfaces, reducing the upper limit of the abutment force between the locking block 505 and the inner groove 506, facilitating the replacement of the filter plate 502 via the filter plate replacement structure 600.

[0050] To improve the ease of disengaging the locking block 505 from the inner groove 506, preferably, the locking block 505 is slidably disposed on the side wall of the first groove 503 or the outer surface of the filter plate 502 by means of a spring. Based on this, when replacing the filter plate 502, the locking block 505 can be pushed and retracted, reducing the contact area with the inner groove 506 and improving the ease of replacing the filter plate 502.

[0051] The filter plate replacement structure 600 is used to replace the filter plate 502 to restore filtration performance. However, during the use of the same filter plate 502, on the one hand, it is necessary to clean the large particles that are trapped, and on the other hand, the clogging gradually worsens. The filter plate 502 is only replaced when the clogging becomes severe. However, before replacing the filter plate 502, the filtration performance gradually decreases. In order to improve the performance of the same filter plate 502, optionally, one of the opposite ends of the filter frame 501 is constructed as a rotating end, and the other end is constructed as a lifting end connected to the first telescopic device 507. Correspondingly, the rotating end is connected to the filter plate replacement structure 600, and the lifting end is connected to the filter cake collection structure 700.

[0052] Based on the above design scheme, such as Figure 3 As shown, when the filter plate 502 separates the mixture, the first telescopic device 507 is activated, causing the filter frame 501 to rotate around the rotating end, so that both the filter frame 501 and the filter plate 502 are tilted, with the rotating end at the bottom and the lifting end at the top. Based on this, when the mixture contacts the filter plate 502, the mixture will flow towards the rotating end under the action of gravity, and the mixture will be separated in the part of the filter plate 502 near the rotating end, reducing the probability that the solution and small particles will enter the filter residue collection structure 700 through the slag outlet 102, and large particles will gradually accumulate on the part of the filter plate 502 near the rotating end.

[0053] After the mixture is separated, the first expansion joint 507 is activated again, causing the filter frame 501 to rotate around its rotating end. This tilts both the filter frame 501 and the filter plate 502, with the rotating end at the top and the lifting end at the bottom. Based on this, the filter plate 502 tilts towards the discharge hole 102. Large particles slide along the filter plate 502 under gravity and then into the filter residue collection structure 700, clearing away the trapped large particles and preventing them from affecting the filtration capacity of the filter plate 502. Furthermore, timely removal of large particles effectively prevents particles with a diameter close to the filter pores from entering the pores under gravity, thus reducing clogging of the filter plate 502 and helping to extend its service life.

[0054] Accordingly, the connection between the intermediate channel 101 and the rotating end is constructed as a flexible waterproof layer 103. The filter frame 501 is rotatably disposed within the flexible waterproof layer 103, and a third groove is provided on the flexible waterproof layer 103 to connect to the filter plate replacement structure 600. Based on this, the flexible waterproof layer 103 can be made of any suitable commercially available material, ensuring the rotational capability of the filter frame 501 and preventing obstruction of its rotation, while also reducing leakage of solutions and preventing the mixed liquid from corroding the components inside the circulating gastrointestinal cleansing device. Simultaneously, the third groove ensures connection to the filter plate replacement structure 600, facilitating the replacement of the filter plate 502.

[0055] For the lifting end, the first expansion joint 507 has two output ends, which are respectively connected to both sides of the lifting end of the filter frame 501. Alternatively, there are two first expansion joints 507, which are respectively connected to both sides of the lifting end of the filter frame 501. This reduces the probability of large particles contacting the first expansion joint 507, reduces corrosion of the first expansion joint 507, and avoids the first expansion joint 507 hindering the sliding of large particles.

[0056] In this embodiment, the filter plate replacement structure 600 includes a slide rail 601 and a second telescopic device 602. Two slide rails 601 are provided and arranged opposite each other. The two opposing slide rails 601 form a filter plate slide. The upper end of the filter plate slide extends and connects to the top surface of the trolley 100, and the lower end of the filter plate slide abuts against the middle channel 101. The second telescopic device 602 is located outside the filter plate slide and is used to push the filter plate 502. Correspondingly, the trolley 100 is provided with a replacement port 104 adapted to the upper slide rail 603.

[0057] Based on the above design, the worker places the filter plate 502 into the trolley 100 through the replacement port 104. The filter plate 502 passes through the replacement port 104 and falls onto the filter plate slide, sliding along the slide until it reaches the vicinity of the middle channel 101. At this point, the filter plate 502 is in the position to be replaced. When the filter plate 502 needs to be replaced, the filter frame 501 rotates under the drive of the first telescopic device 507 until the filter frame 501 and the filter plate 502 to be replaced are on the same plane. Then, the second telescopic device 602 is activated to push the filter plate 502 to be replaced into the filter frame 501 through the third groove. The old filter plate 502 is squeezed out of the filter frame 501 by the filter plate to be replaced, thus replacing the filter plate 502.

[0058] Preferably, such as Figure 2 As shown, when the filter plate replacement structure 600 is used to replace the filter plate, the filter frame 501 is tilted with the rotating end on top and the lifting end on the bottom. Correspondingly, the rotating end is connected to the filter plate replacement structure 600 through the third groove, and the lifting end is connected to the filter residue collection structure 700. Based on this, the replacement of the filter plate 502 is realized, and the replaced filter plate 502 is also conveniently collected. That is, the squeezed-out filter plate 502 can enter and slide along the filter residue collection structure 700 under the action of gravity, and then the filter plate 502 is collected by the filter residue collection structure 700.

[0059] In one possible implementation, the filter plate slide is divided into an upper slide 603 and a lower slide 604 connected together. The upper end of the upper slide 603 extends and connects to the top surface of the trolley 100. The length of the lower slide 604 is adapted to the length of the filter plate 502. The lower end of the lower slide 604 abuts against the middle channel 101, and a limiting block 605 is provided near the middle channel 101 when it slides down. Correspondingly, the replacement port 104 is connected to the upper slide 603. The second telescopic device 602 is located below the upper slide 603, and the telescopic end of the second telescopic device 602 faces the lower slide 604.

[0060] Based on the above design, the upper slide 603 is used to connect the top surface of the trolley 100 so that the staff can place the filter plate 502 to be replaced into the filter plate replacement structure 600. The lower slide 604 is used to temporarily store the filter plate 502 to be replaced. The lower slide 604 is provided with a limiting block 605, which prevents the filter plate 502 to be replaced from contacting the flexible waterproof layer 103 and prevents the end of the filter plate 502 to be replaced from being inserted into the third groove. On the one hand, this prevents the filter plate 502 to be replaced from interfering with the rotation of the flexible waterproof layer 103, and on the other hand, it prevents the rotation of the flexible waterproof layer 103 from damaging the filter plate 502 to be replaced, thus protecting the filter plate 502 to be replaced.

[0061] When the second telescopic device 602 is activated, the filter plate 502 to be replaced can pass over the limiting block 605 and enter the third groove, thereby realizing the replacement of the filter plate 502; or, the limiting block 605 is connected to the sliding track 604 by a spring, and the sliding track 604 is provided with a snap-fit ​​groove adapted to the limiting block 605. When the second telescopic device 602 pushes the filter plate 502 to be replaced, the limiting block 605 compresses the spring and inserts into the snap-fit ​​groove to avoid blocking the movement of the filter plate 502 to be replaced.

[0062] As is easy to understand, both the first telescopic joint 507 and the second telescopic joint 602 provide driving force, and either one can be any suitable commercially available model.

[0063] In one possible implementation, the replacement port 104 is provided with a cover plate, which is rotatably connected to the side wall of the replacement port 104 via a torsion spring. Based on the above design, the cover plate shields the replacement port 104 to reduce the intrusion of dust and other impurities, thereby protecting the various components inside the circulating gastrointestinal cleansing device.

[0064] In this embodiment, the filter cake collection structure 700 includes a filter cake channel 701 and a collection box 702. One end of the filter cake channel 701 is connected to the intermediate channel 101 through a discharge hole 102, and the other end of the filter cake channel 701 is connected to the collection box 702. The collection box 702 is slidably mounted on the trolley 100. Based on the above design, large particles enter the filter cake channel 701 through the discharge hole 102, slide along the filter cake channel 701, and enter the collection box 702. Since the collection box 702 is slidably mounted on the trolley 100, the collection box 702 can be pulled out to remove it from the trolley 100, making it easier to remove the replaced filter plate 502 and to clean the large particles inside the collection box 702, thus restoring the collection capacity of the collection box 702.

[0065] Optionally, baffles 703 are provided on both sides of the filter cake channel 701 to guide the direction and prevent large particles from falling out. Based on this, when the first expansion joint 507 is located below the filter cake channel 701, a suitable perforated structure should be provided on the filter cake channel 701 to facilitate the raising and lowering of the expansion end of the first expansion joint 507. There is a gap between the perforated structure and the first expansion joint 507. To prevent large particles of filter cake from falling through the gap, a suitable dynamic sealing structure needs to be provided.

[0066] Conversely, preferably, such as Figure 2 and Figure 3 As shown, when the first expansion joint 507 is fixed on the outer surface of the intermediate channel 101, the first expansion joint 507 is located above the filter cake channel 701. Based on this, there is no need to set up a hole structure and a dynamic sealing structure, the structure is simpler and there are fewer parts. At the same time, there is no need to worry about the filter cake falling off, making it safer to use.

[0067] Considering the viscosity of gastrointestinal contents, although the viscosity can be reduced after forming a mixture, large particles may still adhere to the filter cake channel 701. To avoid this, preferably, a vibrator is connected to the bottom of the filter cake channel 701, and the output end of the vibrator is connected to the filter cake channel 701. Based on this, the vibration of the vibrator accelerates the downward movement of large particles, preventing them from adhering to the filter cake channel 701.

[0068] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
