[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; for those of ordinary skill in the art, the specific meaning of the above terms in the present utility model can be understood according to specific situations.

[0028] The working principle of the present utility model: As Figure 1 , Figure 2 A blood purification adsorption tank includes an outer shell 1. The outer shell 1 is a cylindrical structure with openings at both the upper and lower ends, and sealing covers 2 are connected to the upper and lower ends. The sealing covers 2 are threadedly connected to the outer shell 1, and a sealing strip is provided therebetween, with simple connection and good sealing effect; an outlet 201 is provided on each of the sealing covers 2; blood enters from the upper sealing cover and is discharged from the lower sealing cover after adsorption and purification;

[0029] As Figure 2 shown, it includes an inner upper sealing cover 3, a first adsorption core 4, a second adsorption core 5, and an inner lower sealing cover 6. The first adsorption core 4 is located between the inner upper sealing cover 3 and the inner lower sealing cover 6. The second adsorption core 5 is located at the center of the first adsorption core 4 and is connected to the inner lower sealing cover 6. Blood enters the inner upper sealing cover and then enters the cavity surrounded by the outer shell. After being adsorbed and filtered by the first adsorption core and the second adsorption core, it is discharged from the lower sealing cover;

[0030] Both the inner upper sealing cover 3 and the inner lower sealing cover 6 are conical structures, and their ends respectively extend to the outlet 201 of the sealing cover 2, so that the sealing and flow effects are good;

[0031] As Figure 6 shown, a snap ring 301 for fixing the first adsorption core 4 is provided at the bottom of the inner upper sealing cover 3. The snap ring 301 is provided with a plurality of notches, which is convenient for observing whether the first adsorption core is installed in place, and the snap ring will not affect the use of the upper end of the first adsorption core, resulting in waste of resources;

[0032] As Figure 7 shown, a conical flow channel 302 is provided inside the inner upper cover 3, and annular through holes 303 are evenly provided at the bottom. The through holes 303 are located outside the snap ring 301. Blood flows along the conical flow channel and then is discharged through the through holes, so that it will not accumulate at the center of the inner upper cover;

[0033] As Figure 3 shown, the first adsorption core 4 includes a filter screen 401 and a fixing net 402. The filter screen 401 has a pleated structure, and the fixing net 402 is arranged outside the filter screen 401. A pipe orifice 403 for installing the second adsorption core 5 is provided at the center of the filter screen 401. The pleated filter screen can increase the contact area with blood and improve the filtering and adsorption effect, and the fixing net can prevent the first adsorption core from deforming during use;

[0034] As Figure 4 、 Figure 5 shown, the blood passing through the first adsorption core enters the second adsorption core along the hollow part, and after being secondarily adsorbed and filtered by the adsorption filter material, it is discharged from the inner lower cover. The second adsorption core 5 is a tubular structure with one end open, and an adsorption filter material 501 is provided at the opening. The upper end of the adsorption core is a closed structure for easy installation. A plurality of filter holes 502 are provided in the circumferential direction of the second adsorption core 5.

[0035] An installation ring 601 for installing the second adsorption core 5 is provided at the bottom of the inner lower cover 6, and a pipe 602 communicating the second adsorption core 5 and the outlet 201 is provided inside the installation ring 601.

[0036] Sealing rings are provided between the inner upper cover 3 and the inner lower cover 6 and the cover 2, and between the inner upper cover 3 and the inner lower cover 6 and the outlet 201.

[0037] A dialysate inlet and a waste liquid outlet can be added to the side wall of the outer shell as needed, but this is not within the protection scope of the present technical solution, so it is not reflected in the technical solution.

[0038] Specific implementation method: The pipes are respectively connected to the outlets of the covers. The pipes are connected to the outlets in a wrapped manner. Blood enters from the upper end and is discharged from the lower end. Blood enters the inner upper cover from the outlet, flows along the conical flow channel and is discharged from the through holes into the outer shell. After being adsorbed and purified by the first adsorption core, it enters the second adsorption core along the filter holes, and after being adsorbed and filtered by the adsorption filter material, it enters the pipe and is then discharged from the cover located at the lower end. The outer shell can be filled with an adsorption filter material that can filter macromolecules, and the second adsorption core can be filled with an adsorption filter material that can adsorb and filter small molecules; Two waste liquid outlets can be designed, which are respectively connected to the outer shell and the upper end of the second adsorption filter element, and the dialysate port can be directly connected to the upper part of the outer shell.

[0039] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
