[0039] The specific application of the embodiment one is: when the blood of the patient needs to be adsorbed and dialysis operation, the external dialysate is injected into the inside of the cylindrical shell 601 through the dialysis inlet pipe 605 (a one-way valve is arranged on the pipeline in communication with the dialysis inlet pipe 605, to avoid backflow), in the process of entering of the external dialysate through the dialysis inlet pipe 605, the flowing dialysate will generate a greater impact force on the sliding ring 905 and the conical cover 906 fixed on the inner wall of the sliding ring 905, so as to stretch the first spring 907 fixedly connected between the sliding ring 905 and the outer threaded pipe 901, so that the sliding ring 905 and the conical cover 906 fixed on the inner wall of the sliding ring 905 are impacted to a certain extent under the impact and flow rate of the dialysate itself, so that the lower extension rod 908 fixed at the bottom of the sliding ring 905 and the sliding ball 909 fixed at the bottom end of the lower extension rod 908 slide on the top of the inclined plate 507 arranged obliquely,This causes the inclined plate 507, with its inclined sides and the fitting rods 508 fixed to one end, to gradually approach one side of the horizontal plate 608. This causes the two guide rods 504, which are inserted and fixed to one side of the connecting plate 506, to slide synchronously inside the two guide holes 610. This stretches the second spring 612, which is fixed between the turbulence cylinder 510 and the connecting plate 506, and causes the semi-circular ring 501 to slide on the outer circumference of the adsorption cylinder 401. This causes the extension rod 502 fixed to the inner wall of the semi-circular ring 501 and the sliding ball 503 fixed to the end of the extension rod 502 to slide synchronously on the threaded groove 403. This allows the entire adsorption element 4 to rotate circumferentially within a certain range (after entering the adsorption element 4, when blood flows through several adsorption membranes 402, toxins and metabolic wastes in the plasma are selectively adsorbed and removed by the microporous structure on the surface of several adsorption membranes 402). When the flow rate of the dialysate into the cylindrical shell 601 through the dialysate inlet pipe 605 slows down, the flowing dialysate will generate a small impact force on the sliding ring 905 and the conical cover 906 fixed to the inner wall of the sliding ring 905 (the specific flow rate of the dialysate when entering the dialysate inlet pipe 605 can be controlled by an external dialysate delivery device, which is existing technology and is not shown in the figure). (This will not be elaborated on here). Combined with the elastic restoring force of the first spring 907, the lower extension rod 908 fixed to the bottom of the sliding ring 905 and the ball 909 fixed to the bottom end of the lower extension rod 908 slide in the opposite direction on the top of the inclined plate 507. Combined with the elastic restoring force of the second spring 612, the two guide rods 504, inserted and fixed to one side of the connecting plate 506, slide in the opposite direction simultaneously inside the two guide holes 610. This causes the contacting rods 508 fixed to one end of the inclined plate 507 to gradually move away from one side of the horizontal plate 608, thereby causing the semicircular ring 501 to... The outer peripheral side of 401 slides in the opposite direction, causing the extension rod 502 fixed to the inner wall of the semicircular ring 501 and the sliding ball 503 fixed to the end of the extension rod 502 to slide in the opposite direction on the threaded groove 403 simultaneously. This causes the entire adsorption element 4 to reciprocate circumferentially within a certain range. Combined with the flow rate of the dialysate, this allows the adsorption element 4 to rotate forward and backward within a certain range, resulting in more uniform contact between the blood and the adsorption membrane 402, avoiding local saturation. Simultaneously, the periodic forward and reverse rotation promotes the diffusion of target substances (such as toxins and metabolic waste) in the blood, increasing the adsorption rate and enhancing the initial adsorption effect of the blood inside the adsorption element 4.

[0040] During the above operation, the adsorption element 4 reciprocates circumferentially within a certain range, causing the turbulence cylinder 510 fixed on the side of the connecting plate 506 and several spiral auger plates 511 fixed in a circular array on the outer wall of the turbulence cylinder 510 to move back and forth inside the cylindrical shell 601 synchronously. This causes periodic contraction-expansion flow to be generated in the dialysate, enhancing the radial mixing of the fluid and improving the transmembrane mass transfer efficiency of small molecules (such as urea and creatinine) and medium molecules (such as β2-microglobulin). At the same time, the multiple spiral auger plates 511 distributed in a circular array can form symmetrical pressure waves in the dialysate chamber inside the cylindrical shell 601, avoiding dead zones in unidirectional flow and improving the effect of subsequent hemodialysis.

[0041] Example 2, please refer to Figures 1-17 This second embodiment is an improvement on the first embodiment as follows: Specifically, an L-shaped ring rail 613 is fixed to one end of the cylindrical shell 601; a base ring 404 is fixed to the bottom of the adsorption cylinder 401; two symmetrical first guide channels 405 are fixed to the outer wall of the base ring 404; sliding rails 406 are slidably fitted inside the two first guide channels 405; a third spring 407 is fixed between the sliding rails 406 and the base ring 404; and rotating fittings are fixed to the inner wall of the L-shaped ring rail 613 on opposite sides of the two sliding rails 406. The arc-shaped ring rail 408; the top of each of the two sliding rails 406 is fixed with a first pin 409, and the two first pins 409 are rotatably engaged with rotating arms 410 on their circumferential sides; the outer wall of the base ring 404 is connected to a second guide channel 411, and a sliding block 412 is slidably engaged inside the second guide channel 411; the top of the sliding block 412 is fixed with two symmetrical second pins 413, and the two second pins 413 are rotatably engaged with the two rotating arms 410 respectively; a fourth spring 41 is fixed between the sliding block 412 and the base ring 404. 4; A U-shaped vertical plate 415 is fixed to the top of the second guide channel 411. A cross bolt 416 is threaded and rotatably fitted to the top of the U-shaped vertical plate 415. A contact ball 417 is fixed inside the U-shaped vertical plate 415 at the bottom of the cross bolt 416. A trapezoidal plate 418 is fixed to the top of the sliding block 412 and slidably fitted with the contact ball 417. The liquid inlet cap 7 includes a liquid inlet cap 701. A transition tube 702 is connected to the top of the liquid inlet cap 701. A rotatably fitted adsorption plate 418 is connected to the bottom of the transition tube 702. The cylinder 401 has an inlet pipe 703 inside; one end of the cylindrical shell 601 is fixed with a first threaded pipe 614 that is threadedly connected to the inlet cap 701; the outlet cap 8 includes an outlet cap 801, the top of the outlet cap 801 is connected to a pressure ring 802, and the bottom of the pressure ring 802 is fixed with a sealing ring 803; the other end of the cylindrical shell 601 is fixed with a second threaded pipe 615 that is threadedly connected to the outlet cap 801, and the other end of the cylindrical shell 601 is provided with a sealing groove 616 that engages with the sealing ring 803.

[0042] The specific application of the second embodiment is that when the dialyzer is used for dialysis of a patient, the patient's blood is injected through one end of the liquid inlet end cap 701, enters the adsorption cartridge 401 through the transfer pipe 702 and the liquid inlet pipe 703, and then passes through the first threaded pipe 614 and the adsorption membranes 402 arranged in the adsorption cartridge 401, so that the patient's blood is preliminarily adsorbed through the preliminary adsorption of the adsorption membranes 402. After the preliminary adsorption is completed, the patient's blood enters the fiber hollow pipes 303 through the first perforated disc 301. At this time, the dialysis liquid is injected into the inside of the cylindrical shell 601 from the dialysis liquid inlet pipe 605, and the blood in the fiber hollow pipes 303 is dialyzed with the fresh dialysis liquid in the cylindrical shell 601. The used dialysis liquid flows out of the cylindrical shell 601 from the dialysis liquid outlet pipe 606, so as to complete the blood dialysis process in the whole process. The blood after the adsorption and dialysis is finally adsorbed and dialyzed and enters the pressure ring 802 through the second perforated disc 302, and then flows out from the liquid outlet end cap 801 and finally reflows into the patient's body, so as to achieve the effect of simultaneously adsorbing and dialyzing the patient's blood.

[0043] Before the above-mentioned adsorption and dialysis operation is performed, the two arc-shaped ring rails 408 are simultaneously placed in the L-shaped ring rail 613, and then the cross screw 416 is rotated, so that the contact ball 417 fixed in the U-shaped vertical plate 415 at the bottom of the cross screw 416 slowly slides on the inclined surface of the trapezoidal plate 418, and in combination with the fourth spring 414 fixed between the sliding block 412 and the base ring 404, the sliding block 412 slowly slides in the second guide groove 411 towards the side of the outer periphery of the adsorption cartridge 401, so that the two rotating arms 410 rotatingly connected between the two first pin shafts 409 and the two second pin shafts 413 are simultaneously expanded slowly, so as to drive the two sliding rails 406 to move linearly away from each other in the two first guide grooves 405, so as to drive the third spring 407 fixed between the sliding rail 406 and the base ring 404 to be synchronously stretched, so as to drive the arc-shaped ring rails 408 fixed on the opposite sides of the sliding rails 406 to be synchronously close to the inner wall of the L-shaped ring rail 613. After the outer walls of the two arc-shaped ring rails 408 are synchronously attached to the inner wall of the L-shaped ring rail 613, the cross screw 416 is stopped, so as to complete the installation process of the adsorption device 4.
