In practical application, the hand-screwed nut 1212 is a seven-sided hand-screwed nut 1212, and the rounded curved surface and the unique seven-sided combination of the seven-sided hand-screwed nut 1212 are superior to those of the conventional hand-screwed nut 1212, so that the hand feeling is better; the locking screw 1211 is a 10mm stainless steel screw having good corrosion resistance. In a preferred embodiment, the angle β between the axis X of the fastening element 121 and the axis Y of the fixing base 11 is 87 °. By so arranging, the fixing assembly 10 can be more stably fixed to the outer bearing member.

Referring to fig. 1 and 12, the clamping assembly 20 includes a mounting base 21 detachably connected to the rotating connecting member 32, a fixed clamping arm 22 fixedly disposed on the mounting base 21, and a movable clamping arm 23 rotatably connected to the fixed clamping arm 22, wherein the fixed clamping arm 22 and the movable clamping arm 23 cooperate to clamp the blood purifier. Through will moving arm 23 and rotate to be connected in fixed arm 22, can the not blood clarifier of equidimension of centre gripping between fixed arm 22 and the movable arm 23, satisfy user's different demands.

As an embodiment, the number of the movable clamping arm 23 and the fixed clamping arm 22 is two, and one movable clamping arm 23 and one fixed clamping arm 22 cooperate to clamp one blood purifier. Through setting up two and moving arm lock 23 and two and decide arm lock 22, centre gripping subassembly 20 both can the centre gripping single blood clarifier, also can centre gripping two blood purifiers simultaneously, can satisfy the fixed needs of departments such as nephrology branch of academic or vocational study, emergency call. Of course, in other embodiments, the number of the movable clamping arms 23 and the fixed clamping arms 22 is three, four or five.

Referring to fig. 12, a pipeline clamp structure 24 is disposed on a side of the movable clamping arm 23 opposite to the fixed clamping arm 22. Through setting up pipeline clamp structure 24, can be used for accomodating the complicated pipeline of the intricacy that involves in the treatment process, avoid the pipeline too littlely. It is understood that in other embodiments, the side of the fixed clip arm 22 facing away from the movable clip arm 23 is provided with the pipe clip structure 24, or both the side of the movable clip arm 23 facing away from the fixed clip arm 22 and the side of the fixed clip arm 22 facing away from the movable clip arm 23 are provided with the pipe clip structure 24.

Referring to fig. 1 and 12, the embodiment of the present invention further provides a blood purification system, which includes a blood purification apparatus, a blood purifier connected to the blood purification apparatus, and the fixing device 100, wherein the blood purifier is fixed on the holding assembly 20. By adopting the fixing device 100 to fix the blood purifier, the manufacturing cost of the blood purifying equipment and the use cost of users are reduced, the angle of the blood purifier can be quickly and conveniently adjusted, and the separation and disinfection according with clinical requirements are realized.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention, which are made by using the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
