The dialyzer 01 is pushed with a little force to be stuck in the clamp assembly 3. Then, the dialyzer 01 is moved upward until the blood inlet at the upper end of the dialyzer 01 hits the first clamp assembly 2, so that the first clamp assembly 2 blocks the blood inlet at the upper end of the dialyzer 01, and at the same time, the dialysate outlet on the dialyzer 01 is aligned with the first connector 21. Head 21, the second clamp assembly 4 moves in the direction close to or away from the clamping assembly 3, and then the second clamp assembly 4 is controlled to move in the direction close to the clamping assembly 3, so that the second clamp assembly 4 blocks the blood outlet at the lower end of the dialyzer 01. At this time, the dialysate inlet of the dialyzer 01 is aligned with the second connector 41, and the dialysate outlet of the dialyzer 01 is aligned with the first connector 21. The first connector 21 and the second connector 41 both move in the direction close to and away from the dialyzer 01.

[0042] The dialyzer centering adjustment tooling set up in the above manner is used to first adjust the position of the second connector 41 according to the size of the dialyzer 01 using the tooling, and then the dialyzer 01 is placed vertically so that the dialysate outlet of the dialyzer 01 is roughly aligned with the first connector 21, the dialyzer 01 is clamped into the clamping assembly 3, and then the dialyzer 01 is moved upward so that the first clamp assembly 2 blocks the blood inlet at the upper end of the dialyzer 01, and then the second clamp assembly 4 is moved upward so that the second clamp assembly 4 blocks the blood outlet at the lower end of the dialyzer 01, and at the same time, the first connector 21 and the second connector 41 are docked with the dialysate outlet and dialysate inlet of the dialyzer 01 to achieve the centering of the dialyzer 01. The entire operation process is fast, convenient and accurate, and can effectively improve the centering efficiency of the dialyzer 01. The deviation in the left and right directions when the dialysate inlet and the dialysate outlet of the dialyzer 01 are aligned with the connector can be limited. The connector can be easily aligned by simply moving the dialyzer 01 up and down. Manual operation is more convenient and efficient. It is also suitable for dialyzers 01 of different sizes and lengths, saving tooling costs to a certain extent.

[0043] Please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6The first clamp assembly 2 also includes a fixed plate 22 and a support plate assembly 24. The fixed plate 22 is vertically arranged on the front of the back plate 1. The first clamp 23 is connected to the fixed plate 22. The support plate assembly 24 is vertically arranged on the bottom of the fixed plate 22. The support plate assembly 24 is movably arranged on the fixed plate 22. The support plate assembly 24 is used to limit the moving position of the first joint 21. The back side of the back plate 1 is provided with a first cylinder 25 connected to the first joint 21, and the first cylinder 25 is connected to the controller signal.

[0044] It should be noted that the fixing plate 22 is fixedly connected to the back plate 1, and the first clamp 23 is fixed to the front end of the fixing plate 22. The first clamp 23 is used to block the upper end of the dialyzer 01. The function of the support plate assembly 24 is to limit the deviation in the left and right directions when the dialysate inlet of the dialyzer 01 is aligned with the first connector 21 and the dialysate outlet is aligned with the second connector 41. The dialyzer 01 only needs to be moved up and down to easily align with the first connector 21 and the second connector 41, limiting the position of the first connector 21 and the second connector 41 when blocking the dialysate inlet and the dialysate outlet of the dialyzer 01 forward.

[0045] Please refer to Figure 5 The fixing plate 22 is provided with an adjusting long hole 221, and the support plate assembly 24 is connected to the fixing plate 22 through the adjusting long hole 221 and the bolt 222. The bottom of the fixing plate 22 is provided with a limiting groove 223 for limiting the movement of the support plate assembly 24.

[0046] It can be understood that an adjustment long hole 221 is opened on the fixing plate 22, and the support plate assembly 24 can be adjusted to the front and rear positions by bolts 222 and fixed on the fixing plate 22. A limiting groove 223 of a certain length is provided at the place where the lower part of the fixing plate 22 contacts the support plate assembly 24 to limit the maximum position of the support plate assembly 24 moving forward.

[0047] Please refer to Figure 6 The support plate assembly 24 includes a first centering support plate and a second centering support plate arranged in parallel at the bottom of the fixed plate 22. Both the first centering support plate and the second centering support plate are provided with an L-shaped groove 241 for limiting the first joint 21.

[0048] It should be noted that an L-shaped groove 241 is respectively formed on the first pair of centering support plates and the second pair of centering support plates, and the first connector 21 is sandwiched between the L-shaped grooves 241 .

[0049] When using the tooling, the position of the second connector 41 is first adjusted according to the size of the dialyzer 01 using the tooling, and then the dialyzer 01 is placed vertically so that the dialysate outlet of the dialyzer 01 is roughly aligned with the first connector 21. The dialyzer 01 is clamped into the clamping assembly 3, and then the dialyzer 01 is moved upward so that the first clamp assembly 2 blocks the upper end of the dialyzer 01. At the same time, when the dialyzer 01 is moved upward, the dialysate outlet of the dialyzer 01 moves upward along the gap between the first pair of centering support plates and the second pair of centering support plates, and the dialysate outlet of the dialyzer 01 is restricted by the first pair of centering support plates and the second pair of centering support plates. When the upper end of the dialyzer 01 abuts against the first clamp 23, the first clamp 23 blocks the upper end of the dialyzer 01. At this time, the controller controls the first cylinder 25 to start, so as to drive the first connector 21 to move forward and dock with the dialysate outlet of the dialyzer 01.

[0050] Please refer to Figure 2 and Figure 3 The second clamp assembly 4 also includes a distance adjustment assembly 42 for adjusting the position of the second joint 41. A second cylinder 43 connected to the second joint 41 is provided on the back side of the back plate 1, and the second cylinder 43 is connected to the controller signal.

[0051] It can be understood that when using the tooling, the position of the distance adjustment component 42 is first adjusted according to the size of the dialyzer 01 using the tooling to adjust the position of the second connector 41, and at the same time drive the second cylinder 43 to move synchronously. When the dialysate inlet and dialysate outlet of the dialyzer 01 are aligned with the second connector 41 and the first connector 21 respectively, the controller controls the first cylinder 25 and the second cylinder 43 to start at the same time to drive the first connector 21 and the second connector 41 to move forward synchronously, so that the first connector 21 is docked with the dialysate outlet of the dialyzer 01, and the second connector 41 is docked with the dialysate inlet of the dialyzer 01.

[0052] Please refer to Figure 7 The distance adjustment assembly 42 includes a first adjustment support plate 421 and a second adjustment support plate 422 for clamping the second joint 41.

The second adjustment support plate 422 is connected to the second cylinder 43.

[0053] It should be noted that the first adjustment support plate 421 is fixed to the back plate 1. The first adjustment support plate 421 and the second adjustment support plate 422 are arranged vertically and connected by an adjustment screw 423. The adjustment screw 423 passes through the first adjustment support plate 421 and is fixed to the second adjustment support plate 422. The adjustment screw 423 moves up and down to drive the second adjustment support plate 422 to move up and down, thereby adjusting the position of the second adjustment support plate 422. The second joint 41 is sandwiched between the first and second adjustment support plates 421 and 422. The second joint 41 and the second adjustment support plate 422 are connected to the corresponding second cylinder 43 behind the back plate 1 through the back plate 1. The second adjustment support plate 422 is fixed to the back plate 1 by tightening the screws on the second adjustment support plate 422. Loosening the screws on the second adjustment support plate 422 can drive the second joint 41 and the second cylinder 43 connected to the back plate 1 to move up and down along the track on the back plate 1 through the adjustment screw 423 to accommodate the requirements of dialyzers 01 of different lengths. After the size of the dialyzer 01 is determined, the position of the second connector 41 is determined by adjusting the second adjustment support plate 422 , and then the second adjustment support plate 422 is fixed in place.

[0054] In the above embodiment, the second clamp assembly 4 also includes a third cylinder 44 provided on the front side of the back plate 1. The output end of the third cylinder 44 moves in a direction close to or away from the clamping assembly 3. The output end of the third cylinder 44 is connected to the lifting plate 45. The lifting plate 45 is provided with a second clamp 46. The second clamp 46 is symmetrically arranged with the first clamp 23. The third cylinder 44 is connected to the controller signal.

[0055] It can be understood that when the dialysate inlet of the dialyzer 01 is docked with the first connector 21 and the dialysate outlet is docked with the second connector 41, the controller controls the third cylinder 44 to start, so as to drive the lifting plate 45 and the second clamp 46 on the lifting plate 45 to move upward, so that the second clamp 46 blocks the lower end of the dialyzer 01.

[0056] As a preferred embodiment, the lifting plate 45 is slidably connected to the back plate 1 through a slide rail assembly. The slide rail assembly includes a slide rail provided on the back plate 1 and a movable slider provided on the slide rail. The slider is connected to the lifting plate 45.

[0057] It should be noted that the second clamp 46 is fixed on the lifting plate 45, and the lifting plate 45 is connected to the third cylinder 44. The third cylinder 44 drives the lifting plate 45 to move up and down along the slide rail on the back plate 1. During the lifting process, the second clamp 46 fixed on the lifting plate 45 also moves up and down.

[0058] In the above case, both the first clamp 23 and the second clamp 46 are provided with a sealing structure.

[0059] It can be understood that by providing sealing structures on the first clamp 23 and the second clamp 46 , both ends of the dialyzer 01 are sealed.

[0060] In the above embodiment, the clamping assembly 3 includes two elastic clamps arranged below the first clamp 23 . The two elastic clamps are arranged one above the other, and each of the elastic clamps is provided with a slot for clamping the dialyzer 01 .

[0061] It should be noted that the two elastic splints are fixed on the back plate 1 and slots are provided to achieve the clamping connection of the dialyzer 01 .

[0062] In summary, the centering adjustment tooling of the dialyzer provided by the present invention, the centering operation steps during the special treatment process of the dialyzer 01 membrane bundle are as follows: according to the size of the dialyzer 01, the position of the second adjustment support plate 422 is adjusted in advance by adjusting the screw 423 and fixed, and the position of the second joint 41 connected to the second adjustment support plate 422 is also fixed accordingly, and at the same time, the position of the support plate assembly 24 fixed on the fixed plate 22 is adjusted so that the first joint 21 can accurately block the dialysate outlet of the dialyzer 01 forward and the second joint 4 ... 41 can accurately block the dialysate inlet of the dialyzer 01 forward. Place the dialyzer 01 vertically so that the dialysate outlet at the upper end of the dialyzer 01 is roughly aligned with the first connector 21. Push the slots of the two elastic splints with a little force to respectively clamp the dialyzer 01 shell. Move the dialyzer 01 upward until the upper end of the dialyzer 01 is pushed into the first clamp 23. At the same time, the dialysate outlet at the upper end of the dialyzer 01 moves upward along the middle gap between the first pair of support plates and the second pair of support plates, aligning it with the first connector 21, so that the lower end of the dialyzer 01 is aligned with the dialyzer 01 shell. The dialysate inlet is also aligned with the second joint 41. The lifting plate 45 fixed with the second clamp 46 moves upward under the drive of the second cylinder 43. The first clamp 23 and the second clamp 46 respectively clamp the two ends of the dialyzer 01 to seal. The first joint 21 and the second joint 41 are driven by the first cylinder 25 and the second cylinder 43 corresponding to the back of the back plate 1 to move forward to the limit position, respectively blocking the dialysate inlet and the dialysate outlet of the dialyzer 01. The dialyzer 01 is manually shaken to confirm whether it is blocked. If dialyzer 01 cannot be moved, it proves that the seal is intact. After the special treatment of dialyzer 01 is completed, the first connector 21 and the second connector 41 are driven by the corresponding cylinders behind the back plate 1 to move backward, releasing the dialysate inlet and dialysate outlet of dialyzer 01. The lifting plate 45, which fixes the second clamp 46, is driven downward by the third cylinder 44, thereby releasing the first clamp 23 and the second clamp 46 sealing the upper and lower ends of dialyzer 01. The dialyzer 01 is then grasped by hand and pulled out from the two elastic clamps. The special treatment process for the entire set of dialyzers 01 is carried out in this manner.

[0063] This centering adjustment tool is used during the centering operation of the dialyzer 01 membrane bundle during special processing. It can limit the left-right deviation of the dialyzer 01's dialysate outlet and dialysate inlet when docking with the first connector 21 and the second connector 41. The first connector 21 and the second connector 41 can be easily aligned by simply moving the dialyzer 01 up and down. It can also limit the position of the first connector 21 and the second connector 41 when they are forward blocking the dialyzer 01's dialysate outlet and dialysate inlet. To make manual operation more convenient and efficient and reduce production costs, it is also suitable for dialyzers 01 of different sizes and lengths, saving tooling costs to a certain extent.
