Description
Technical Field
[0001] This invention belongs to the field of ascites drainage technology, specifically an ascites drainage device for the care of liver cirrhosis. Background Technology
[0002] Cirrhosis is an irreversible liver fibrosis disease. Due to the loss of liver function, these patients usually have ascites in their abdomen, and the amount of ascites is usually moderate or large. The ascites is usually cleared by puncture drainage.
[0003] For example, invention application CN119075025A discloses a clinical ascites drainage device in the field of ascites drainage technology. The device includes a fixing box with a silicone pad fixedly connected to its side wall; a fixing pipe disposed within the fixing box and located in the middle of the fixing box; a connecting pipe rotatably connected to the end of the fixing pipe, with a drainage hose fixedly connected to its side wall for draining ascites; a sample collection bottle installed on the connecting pipe, with an automatic control valve at its top for controlling the opening of the sample collection bottle; and an ascites collection component connected to the lower end of the drainage hose, facilitating the sampling of any obstructions remaining in the drainage tube within the patient's body.
[0004] Based on the above cases and actual situations, we have identified the following issues: During ascites drainage, patients with cirrhosis generally have a large amount of ascites, which inevitably contains tissue. This tissue may block the drainage tube during drainage, increasing the patient's safety risks. When the drainage tube is blocked, medical staff need to directly squeeze it to clear the blockage. This is not only cumbersome, but manual squeezing may not completely clear the blockage. Furthermore, subsequent replacement of the collection bag or cleaning of the collection container may not completely close the drainage tube, easily increasing the patient's risk of infection. Summary of the Invention
[0005] The purpose of this invention is to provide an ascites drainage device for the care of patients with liver cirrhosis, so as to solve the above-mentioned problems of the prior art.
[0006] To achieve the above objectives, the present invention provides an ascites drainage device for the care of liver cirrhosis, comprising a collection component for collecting ascites and a drainage tube assembly for draining ascites, wherein the drainage tube assembly is provided with a clearing component for clearing tissue blockages within the drainage tube assembly.
[0007] The unblocking component includes a movable sleeve structure movably sleeved on the drainage tube assembly, two squeezing structures for squeezing the drainage tube assembly, a pressing structure for triggering the squeezing structures to contract and squeeze, and a handle structure for pushing the pressing structure.
[0008] The movable sleeve structure includes a cylindrical movable sleeve, an installation groove located in the middle of the inner wall of the movable sleeve, and a pressing groove located in the middle of the outer wall of the movable sleeve for setting a handle structure.
[0009] The pressing structure includes a fixing mechanism fixed to the front wall of the mounting groove, a movable ring rotatably connected to the rear wall of the mounting groove, and a transmission rod symmetrically arranged at the upper and lower centers for pushing the movable ring to rotate. The fixing mechanism includes a fixing ring, two movable grooves symmetrically arranged at the centers inside the fixing ring, and a toothed plate fixed to the inner wall of the outer ring groove of the movable groove.
[0010] The extrusion structure is disposed between the movable ring and the fixed ring. The extrusion structure includes an extrusion plate for extruding the drainage tube assembly and a gear fixed coaxially to one end of the extrusion plate. The gear meshes with the toothed plate on the corresponding side.
[0011] In the technical solution of the present invention, the collection component includes a collection bucket for collecting ascites caused by liver cirrhosis and two first magnetic buckles for magnetically fixing the movable sleeve. The front side wall of the movable sleeve is symmetrically provided with first magnetic grooves corresponding to the two first magnetic buckles one by one. The top surface of the collection bucket is symmetrically provided with two sets of limiting bolts for fixing the handle structure.
[0012] In the technical solution of the present invention, the drainage tube assembly includes a drainage tube, a needle communicating with the front end of the drainage tube, and a stop provided between the drainage tube and the needle. The front side wall of the stop is symmetrically provided with second magnetic buckles, and the rear side wall of the movable sleeve is provided with two second magnetic grooves corresponding one-to-one with the two second magnetic buckles.
[0013] In the technical solution of the present invention, a limiting ring is fixed at the same center on the rear side wall of the movable ring, and the rear groove wall of the mounting groove is provided with a ring groove adapted to the limiting ring. The groove wall of the mounting groove is provided with two rod grooves for the corresponding transmission rod to rotate, and the two rod grooves are symmetrically arranged at their upper and lower centers.
[0014] In the technical solution of the present invention, the two extrusion structures are arranged symmetrically at the center and staggered back and forth. The extrusion plate is in the shape of a quarter circle arc. One end of the extrusion plate is rotatably connected to the front side wall of the movable ring, and the other end is unrestricted. The rotatably connected end of the extrusion plate is coaxially fixed with the gear on the corresponding side, and the extrusion plate is arranged counterclockwise from the rotatably connected end to the free end.
[0015] In the technical solution of the present invention, the outermost end to the innermost end of the upper transmission rod is inclined to the right, the two transmission rods are symmetrically arranged at their centers, and the two ends of the transmission rod are respectively rotatably connected to the handle structure and the movable ring.
[0016] In the technical solution of the present invention, the handle structure includes two handles arranged symmetrically in the upper and lower parts and two fixing blocks arranged symmetrically in the left and right parts. The handles are disposed in the pressing groove, and the fixing blocks are fixed to the groove wall of the pressing groove.
[0017] In the technical solution of the present invention, the handle is arc-shaped to match the pressing groove, and the outermost end of the transmission rod passes through the mounting groove and the pressing groove from the inside to the outside in sequence and is rotatably connected to the middle of the inner sidewall of the handle on the corresponding side.
[0018] In the technical solution of the present invention, the two ends of the handle are fixed with sliding blocks, the sliding blocks extend into the corresponding fixed blocks and the two are slidably connected, the fixed blocks are provided with insert rods, the insert rods extend into the corresponding sliding blocks and the two are slidably connected, and the outer wall of the insert rod located between the fixed blocks and the sliding blocks is fitted with a spring.
[0019] In the technical solution of the present invention, both the fixed block and the sliding block are provided with a plurality of limiting holes corresponding one-to-one with the plurality of limiting bolts.
[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0021] 1. In this invention, by setting up a blockage-clearing component, during blockage clearing, medical staff fix the end of the drainage tube with one hand and hold the handle structure with the other hand. The handle drives the sliding block to slide along the insertion rod in the corresponding fixed block and squeeze the spring. At the same time, it drives the transmission rod to push the movable ring to rotate clockwise, and the squeezing plate and gear will rotate clockwise synchronously. Then, under the action of the toothed plate, the squeezing plate rotates clockwise as a whole while rotating counterclockwise around the end of the gear, so that the two squeezing plates come closer to each other and squeeze the drainage tube assembly. Afterwards, the medical staff holds the movable sleeve structure and slides it along the drainage tube towards the collection bucket end, which can squeeze the tissue in the drainage tube assembly out of the drainage tube. The operation is simple and convenient, and the drainage tube can be completely cleaned.
[0022] 2. In this invention, after the blockage is cleared, the first magnetic buckle and the first magnetic suction groove are aligned and merged to fix the blockage clearing component. At this time, the limiting bolt can restrict the rebound of the handle structure, thereby ensuring that the squeezing plate continues to squeeze the drainage tube component, ensuring the closure of the drainage tube component, and reducing the risk of infection for cirrhotic patients when cleaning the collection bucket later.

[0039] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0040] Unless otherwise expressly stated, throughout this specification, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.
[0041] Reference Figures 1-12 As shown, this embodiment provides a technical solution:
[0042] The ascites drainage device for liver cirrhosis care in this invention includes a collection component 1 for collecting ascites and a drainage tube component 2 for draining ascites. The drainage tube component 2 is provided with a clearing component 3 for clearing tissue blockage inside the drainage tube component 2.
[0043] The unblocking component 3 includes a movable sleeve structure 31 movably sleeved on the drainage tube component 2, two squeezing structures 34 for squeezing the drainage tube component 2, a pressing structure 32 for triggering the squeezing structure 34 to contract and squeeze, and a handle structure 33 for pushing the pressing structure 32. When the drainage tube component 2 is blocked by tissue, medical staff can hold the handle structure 33 with one hand, fix one end of the drainage tube component 2 with the other hand, and drag the movable sleeve structure 31 to slide it along the drainage tube component 2 to clear the blocked tissue from the drainage tube component 2.
[0044] The movable sleeve structure 31 includes a cylindrical movable sleeve 311, an installation groove 314 disposed in the middle of the inner wall of the movable sleeve 311, and a pressing groove 312 located in the middle of the outer wall of the movable sleeve 311 for setting the handle structure 33.
[0045] The pressing structure 32 includes a fixing mechanism 322 fixed to the front wall of the mounting groove 314, a movable ring 323 rotatably connected to the rear wall of the mounting groove 314, and a transmission rod 321 symmetrically arranged at the upper and lower centers for pushing the movable ring 323 to rotate. The fixing mechanism 322 includes a fixing ring 3221, a movable groove 3222 symmetrically arranged at the center inside the fixing ring 3221, and a toothed plate 3223 fixed to the inner wall of the outer ring groove of the movable groove 3222. When the pressing handle structure 33 is pressed, the movable ring 323 will be driven to rotate clockwise through the transmission rod 321.
[0046] The extrusion structure 34 is disposed between the movable ring 323 and the fixed ring 3221. The extrusion structure 34 includes an extrusion plate 341 for extruding the drainage tube assembly 2 and a gear 342 coaxially fixed to one end of the extrusion plate 341. The gear 342 meshes with the corresponding side toothed plate 3223. When the movable ring 323 rotates clockwise, the extrusion plate 341 and the gear 342 will rotate clockwise synchronously. Then, under the action of the toothed plate 3223, the extrusion plate 341 rotates clockwise as a whole while rotating counterclockwise around the end of the gear 342, so that the two extrusion plates 341 move closer to each other and extrude the drainage tube assembly 2. When the movable sleeve structure 31 slides along the drainage tube assembly 2, the tissue in the drainage tube assembly 2 can be squeezed out.
[0047] In addition, such as Figures 1-2 As shown, the collection component 1 includes a collection bucket 11 for collecting ascites caused by cirrhosis and two first magnetic buckles 13 for magnetically fixing the movable sleeve 311. The front side wall of the movable sleeve 311 is symmetrically provided with first magnetic grooves 313 corresponding to the two first magnetic buckles 13. When the movable sleeve structure 31 slides to one end close to the collection bucket 11, the unblocking component 3 can be fixed by the first magnetic buckles 13 and the first magnetic grooves 313. The top surface of the collection bucket 11 is symmetrically provided with two sets of limiting bolts 12 for fixing the handle structure 33. When the unblocking component 3 is fixed to one end of the collection bucket 11, the limiting bolts 12 can restrict the rebound of the handle structure 33, thereby ensuring that the squeezing plate 341 still squeezes the drainage tube assembly 2 to ensure the closure of the drainage tube assembly 2 and reduce the risk of infection when cleaning the collection bucket 11 laterally.
[0048] In addition, the drainage tube assembly 2 includes a drainage tube 21, a needle 22 connected to the front end of the drainage tube 21, and a stop 23 disposed between the drainage tube 21 and the needle 22. The needle 22 is inserted into the body of the patient with cirrhosis. Fixing the needle 22 is existing technology and will not be described in detail here. The front side wall of the stop 23 is symmetrically provided with second magnetic buckles 24. The rear side wall of the movable sleeve 311 is provided with two second magnetic suction grooves 316 that correspond one-to-one with the two second magnetic buckles 24. The unused unblocking assembly 3 is fixed by setting the second magnetic buckles 24 and the second magnetic suction grooves 316.
[0049] Among them, such as Figure 7 and Figure 10 As shown, a limiting ring 324 is fixed to the same center on the rear side wall of the movable ring 323. The rear wall of the mounting groove 314 is provided with an annular groove 315 that matches the limiting ring 324. The limiting ring 324 is engaged in the annular groove 315 and can rotate freely. The mounting groove 314 is provided with two rod grooves 317 for the corresponding transmission rod 321 to rotate, so as to avoid the movable sleeve 311 from affecting the movement of the transmission rod 321. The two rod grooves 317 are symmetrically arranged at the upper and lower centers.
[0050] Specifically, the outermost to innermost end of the upper transmission rod 321 is tilted to the right to ensure that when the handle structure 33 is pressed, the transmission rod 321 will drive the movable ring 323 to rotate clockwise. The upper and lower transmission rods 321 are symmetrically arranged at their centers, and the two ends of the transmission rod 321 are rotatably connected to the handle structure 33 and the movable ring 323, respectively.
[0051] Furthermore, such as Figures 4-9 As shown, the two extrusion structures 34 are arranged symmetrically at the center and staggered back and forth. The extrusion plate 341 is in the shape of a quarter circle arc, which ensures that the two extrusion plates 341 can completely squeeze the drainage tube 21 after rotation, avoiding gaps between the two extrusion plates 341 and resulting in incomplete cleaning. One end of the extrusion plate 341 is rotatably connected to the front side wall of the movable ring 323, and the other end is unrestricted. The rotatably connected end of the extrusion plate 341 is coaxially fixed with the corresponding side gear 342, and the extrusion plate 341 is arranged counterclockwise from the rotatably connected end to the free end, so that when the movable ring 323 rotates clockwise, the two extrusion plates 341 can approach each other and squeeze the drainage tube 21.
[0052] In addition, such as Figures 11-12 As shown, the handle structure 33 includes two handles 331 arranged symmetrically vertically and two fixing blocks 332 arranged symmetrically horizontally. The handles 331 are set in the pressing groove 312, and the fixing blocks 332 are fixed to the groove wall of the pressing groove 312. The handles 331 are arc-shaped and adapted to the pressing groove 312. The outermost end of the transmission rod 321 passes through the mounting groove 314 and the pressing groove 312 from the inside to the outside and is rotatably connected to the middle of the inner side wall of the corresponding handle 331. When the medical staff holds the handle 331, they will squeeze the transmission rod 321, which will push the movable ring 323 to rotate clockwise.
[0053] Furthermore, sliding blocks 333 are fixed at both ends of the handle 331. The sliding blocks 333 extend into the corresponding fixed blocks 332 and the two are slidably connected. The fixed blocks 332 are provided with insert rods 336, which extend into the corresponding sliding blocks 333 and the two are slidably connected. The portion of the outer wall of the insert rod 336 located between the fixed blocks 332 and the sliding blocks 333 is fitted with a spring 335. When the handle 331 is gripped and pressed, the sliding blocks 333 slide along the insert rods 336 in the corresponding fixed blocks 332 and compress the springs 335.
[0054] In addition, both the fixed block 332 and the sliding block 333 are provided with several limiting holes 334 that correspond one-to-one with several limiting bolts 12. When the movable sleeve structure 31 slides to one end close to the collection bucket 11, the limiting bolt 12 will be inserted into the corresponding limiting hole 334 to prevent the spring 335 from rebounding after the medical staff let go, so that the squeezing plate 341 cannot squeeze the drainage tube 21 and thus increase the risk of infection.
[0055] The working principle of the ascites drainage device for liver cirrhosis care in this invention is as follows:
[0056] Before use, the second magnetic buckle 24 and the second magnetic suction groove 316 fix the unblocking component 3. When the drainage tube 21 is blocked by tissue during drainage of a patient with cirrhosis, the medical staff fixes the end 23 of the drainage tube 21 with one hand and holds the handle structure 33 with the other hand. It should be noted that at this time, the movable sleeve 311 is fixed under the action of the second magnetic buckle 24 and the second magnetic suction groove 316, thereby ensuring that the fixing ring 3221 is fixed. After the handle structure 33 is held, the handle 331 drives the sliding block 333 to slide along the insertion rod 336 in the corresponding fixing block 332 and squeeze the spring 335. At the same time, it drives the transmission rod 321 to push the movable ring 323 to rotate clockwise.
[0057] When the movable ring 323 rotates clockwise, the squeezing plate 341 and the gear 342 will rotate clockwise synchronously. Then, under the action of the toothed plate 3223, the squeezing plate 341 rotates clockwise as a whole while rotating counterclockwise around the end of the gear 342, so that the two squeezing plates 341 move closer to each other and squeeze the drainage tube assembly 2. Then, when the medical staff holds the movable sleeve structure 31 and slides it along the drainage tube 21 toward the collection bucket 11, the tissue in the drainage tube assembly 2 can be squeezed out of the drainage tube 21. The operation is simple and convenient.
[0058] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations. The scope of the invention is intended to be defined by the specification and its equivalents.
