[0040] The working principle of the present utility model:

[0041] When it is necessary to place the filling bag, place the filling bag on the placement rack 3, and dial the control board 803 upward to drive the control stopper 802 to rise on the surface of the fixed column 801. When the fixed baffle contacts the control member 605, the control stopper 802 pushes the control member 605 to move. The control member 605 drives the support column 603 and the limit plate 602 to move synchronously. The limit plate 602 drives the limit block 601 to move and compresses the return spring 604. When the control stopper 802 reaches the appropriate position, the force released after the compression of the return spring 604 drives the control member 605 to move in the reverse direction, so that the control member 605 contacts the inner side of the control stopper 802. At the same time, the limit block 601 no longer contacts the lifting gear 502. Rotate the control switch 504 to drive the control column 503 and the lifting gear 502 to rotate synchronously. The lifting gear 502 drives the lifting rack 501 and the placement rack 3 to rise synchronously. When the placement rack 3 reaches the appropriate height, dial the control board 803 downward to push the control member 605 to move. When the control member 605 no longer contacts the inner side of the control stopper 802, the force released after the compression of the return spring 604 drives the limit plate 602 and the limit block 601 to move synchronously in the reverse direction. The limit plate 602 drives the support column 603 and the control member 605 to move in the reverse direction and reset, so that the limit block 601 is clamped with the lifting gear 502 to complete the fixation.

[0042] In summary, for the hemodialysis machine that facilitates the replacement of the filling bag, by setting the combined use of the lifting device 5, the limiting device 6 and the control component 8, it solves the problem that when replacing the filling bag in the existing hemodialysis machine, the height of the filling bag placement rack is mostly fixed. Usually, the user needs to lift the arm to place the filling bag on the placement rack. If the user cannot stably hold the filling bag, it may cause the filling bag to fall, resulting in damage to items or splashing of liquid.
