A blood purification line fixing device according to claim 2, further comprising a lower clamp plate (1) and an upper clamp plate (3), wherein the universal ball seat (29) is connected to the upper clamp plate (3), and wherein the lower clamp plate (1) is connected to the upper clamp plate (3) by a first spring (2); the lower clamp plate (1) is fixedly connected with a screw rod (23), a through hole for the screw rod (23) to pass through is formed in the upper clamp plate (3), and the screw rod (23) is connected with a butterfly nut (4) through the through hole in a threaded manner.
4. A method of using the blood purification tubing set of claim 3, comprising the steps of:
s1: the upper movable seat (21) is opened, so that an arm and a dialysis tube are placed between the upper movable seat (21) and the lower fixed seat (20), and when the arm needs to be moved, the pull rod (19) is driven by a finger to move in a direction away from the outer cylinder column (5);
s2: the pull rod (19) drives the sliding block (25) to move, the movable rod (10) is driven to ascend under the action of the chute, the movable rod (10) drives the diamond frame (11) to gather inwards through the stop block (13), so that the limiting pin (12) is separated from the ratchet, at the moment, the inner cylinder column (17) can slide relative to the outer cylinder column (5), and a user can conveniently and freely adjust the height of the arm;
meanwhile, the movable rod (10) drives the pull rope (8) to move upwards, the pull rope (8) drives the brake block (27) to move upwards, the brake block (27) is not contacted with the universal ball seat (29), and at the moment, the outer cylinder column (5) can freely move around the universal ball seat (29), so that a user can freely move an arm;
when the arm drives the outer cylinder column (5) to move upwards, the pull rod (19) is loosened, under the action of the third spring (24) and the second spring (14), the pull rod (19) is reset, the diamond-shaped frame (11) is reset, and the limiting pin (12) is inserted between the ratchet teeth again, so that the relative fixing of the position of the inner cylinder column (17) is realized, and in the process, the pull rope (8) drives the movable pulley (7) to move upwards, so that the tension spring (6) is further stretched;
after the arm drives the outer cylinder column (5) to move downwards, the pull rod (19) is loosened, under the action of the third spring (24) and the second spring (14), the pull rod (19) is reset, the diamond frame (11) is reset, and the limiting pin (12) is inserted between the ratchet teeth again at the moment, so that the relative fixing of the position of the inner cylinder column (17) is realized, and in the process, the tension spring (6) drives the movable pulley (7) to move downwards.
