A blood purification line fixing device as claimed in claim 4, further comprising a lower plate (1) and an upper plate (3), wherein the universal ball seat (29) is connected with the upper plate (3), and the lower plate (1) is connected with the upper plate (3) through a first spring (2); lower plate (1) fixedly connected with screw rod (23), last splint (3) are seted up and are supplied the via hole that screw rod (23) passed, screw rod (23) pass through threaded connection has butterfly nut (4) behind the hole.
10. A method of using a blood purification line set forth in any one of claims 7-9, comprising the steps of:
s1: the arm and the dialysis tube are placed between the upper movable seat (21) and the lower fixed seat (20) by opening the upper movable seat (21), and when the arm needs to be moved, the pull rod (19) is driven by fingers to move in a direction far 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, the inner cylinder column (17) can slide relative to the outer cylinder column (5), and a user can freely adjust the height of the arm conveniently;
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 in contact with the universal ball seat (29), and the outer cylinder column (5) can freely move around the universal ball seat (29) at the moment, 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, the pull rod (19) resets under the action of the third spring (24) and the second spring (14), the diamond-shaped frame (11) resets, the limiting pin (12) is inserted between the ratchets again at the moment, the relative fixation 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, the pull rod (19) resets under the action of the third spring (24) and the second spring (14), the diamond-shaped frame (11) resets, the limiting pin (12) is inserted between the ratchets again at the moment, the relative fixation 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.
