[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It replaces part of the kidney function and has the functions of clearing excess water and metabolic waste from the body and maintaining electrolyte and acid-base balance.

[0003] After hemodialysis, metabolic waste and water in the blood will enter the dialysate. At this time, the treated dialysis waste fluid needs to be collected and subsequently treated uniformly.

When the drain pipe and the collection box are connected, the drain pipe is plugged into the collection cover on the collection box, and then the drain pipe is squeezed and fixed. After the drain pipe is squeezed and fixed, its fixation stability depends on manual tightening. The squeezing degree of the drain pipe is different, which affects the drainage efficiency. Therefore, we propose a hemodialysis machine drain pipe connection structure. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The embodiment of the present application provides a drainage pipe connection structure for a hemodialysis machine, which solves the problem that after the drainage pipe 301 is squeezed and fixed, its fixing stability depends on manual tightening, and the squeezing degree of the drainage pipe 301 is different, which affects the drainage efficiency. The threaded sleeve 3 is moved to push the sliding rod 401 to move. At this time, the sliding rod 401 pushes the pushing rod 5 to rotate. Under the action of the rotating rod 402, the rotation path of the pushing rod 5 is positioned. When multiple pushing rods 5 rotate, the contact seat 403 on the pushing rod 5 contacts the liquid collecting box mouth, which is convenient for fixing the liquid collecting box and the plug-in sleeve 1, and is convenient and quick to fix in liquid collecting boxes of different sizes. The drainage pipe 301 is not squeezed, so that the drainage efficiency is optimal.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The utility model embodiment discloses a drainage pipe connection structure of a hemodialysis machine.

[0027] According to the attached Figure 1-4 As shown, it includes a plug-in sleeve 1 and a threaded sleeve 3, the top end surface of the plug-in sleeve 1 is fixedly connected with a connecting port 101, the outer wall of the plug-in sleeve 1 is fixedly connected with a positioning seat 2, the threaded sleeve 3 is threadedly connected to the outer peripheral wall of the connecting port 101, and the inner wall of the connecting port 101 is slidably connected with a connecting sleeve 6, and a plurality of connecting grooves are provided on the connecting sleeve 6 for connecting the drain pipe 301 with the plug-in sleeve 1. At this time, the connecting grooves on the connecting sleeve 6 are connected with the plug-in sleeve 1, and the drain pipe 301 is connected with the plug-in sleeve 1, so as to facilitate drainage. The outer wall of the plug-in sleeve 1 is provided with:

[0028] The fixing unit includes a pushing rod 5 and a sliding rod 401. The sliding rod 401 is slidably connected to the inner wall of the positioning seat 2. The sliding rod 401 is rotatably connected to the pushing rod 5. A rotating rod 402 is rotatably connected to the outer wall of the pushing rod 5. The other end of the rotating rod 402 is rotatably connected to the outer wall of the plug-in sleeve 1. The fixing unit is used to adjust the position of the pushing rod 5 to fix the plug-in sleeve 1, and move the threaded sleeve 3 to push the sliding rod 401 to move. At this time, the sliding rod 401 pushes the pushing rod 5 to rotate. Under the action of the rotating rod 402, the rotation path of the pushing rod 5 is positioned. When multiple pushing rods 5 rotate, the contact seat 403 on the pushing rod 5 contacts the liquid collecting box mouth, which is convenient for fixing the liquid collecting box and the plug-in sleeve 1, and is convenient and quick to fix in liquid collecting boxes of different sizes without squeezing the drain pipe 301, so that the drainage efficiency is at the best.

[0029] An extrusion seat 302 is fixedly connected to the outer wall of the threaded sleeve 3, and a connecting seat 4 is attached to the bottom end face of the extrusion seat 302. When the threaded sleeve 3 rotates downward along the outer wall of the connecting port 101, the threaded sleeve 3 drives the extrusion seat 302 to move and push the connecting seat 4.

[0030] The bottom end surface of the connecting seat 4 is fixedly connected to a plurality of sliding rods 401 .

[0031] The end of the push rod 5 is rotatably connected to the contact seat 403. At this time, the slide rod 401 pushes the push rod 5 to rotate. Under the rotation of the push rod 5, the contact seat 403 and the liquid collecting box are tightly squeezed to ensure the fixation of the plug-in sleeve 1 and the liquid collecting box.

[0032] The end of the drain pipe 301 is fixedly connected to a push seat 303, and the bottom end surface of the push seat 303 is fitted with a sliding seat 601. The sliding seat 601 is slidably connected to the inner wall of the plug-in sleeve 1. When the threaded sleeve 3 rotates downward along the connecting port 101, the push seat 303 moves accordingly, pushing the sliding seat 601 to slide.

[0033] A positioning rod 602 is slidably connected to the inner wall of the sliding seat 601 , and the positioning rod 602 is fixedly connected to the inner wall of the plug-in sleeve 1 . Under the action of the positioning rod 602 , the moving path of the sliding seat 601 is limited, so that the movement is more stable.

[0034] A spring 603 is sleeved on the outer peripheral wall of the positioning rod 602 .

[0035] One end of the spring 603 is fixedly connected to the sliding seat 601, and the other end of the spring 603 is fixedly connected to the fixing seat 604, which is fixedly connected to the inner wall of the plug-in sleeve 1. When the sliding seat 601 moves, the connecting sleeve 6 fixedly connected thereto is driven to move. At this time, the connecting groove on the connecting sleeve 6 is connected to the plug-in sleeve 1, and the drain pipe 301 is connected to the plug-in sleeve 1, which is convenient for drainage.

[0036] At the same time, the sliding seat 601 moves to compress the spring 603 between the fixed seat 604 and the sliding seat 601. When the drainage is completed, the threaded sleeve 3 is rotated in the reverse direction so that the threaded sleeve 3 drives the pushing seat 303 to separate from the sliding seat 601.

[0037] Under the rebound of the spring 603 , the sliding seat 601 and the connecting sleeve 6 are pushed to return to the initial position. At this time, the connecting sleeve 6 is sealed with the connecting port 101 , so that the liquid in the drain pipe 301 cannot enter the plug-in sleeve 1 .

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
