The nutrient solution infusion rack for the patients with hepatobiliary disease in general surgery according to claim 1, wherein: place the right side on frame (8) bottom surface and seted up and hide the recess, the inner chamber of hiding the recess is inlayed and is had control switch, control switch's output and heating baffle (34) electric connection.

9. The method of use of a frame for the infusion of nutritional fluids for patients with hepatobiliary disease in general surgery according to any one of claims 1 to 8, comprising the following steps:

A) when the supporting upright post (5) needs to rotate, the lifting sleeve (6) is moved upwards to drive the positioning disc (21), the lifting rod (17) rises and the reset spring (16) is compressed, the connecting spring (18) is compressed at the moment, the L-shaped inserted rod (2) moves upwards to be separated from the inner cavity of the positioning insertion hole (24), the lifting sleeve (6) stops moving upwards after the rotating supporting upright post (5) reaches a proper angle, and the positioning disc (21), the lifting rod (17) and the L-shaped inserted rod (2) are reset to enter the inner cavity of the positioning insertion hole (24) to complete the re-positioning of the supporting upright post (5) under the reset action of the connecting spring (18) and the reset spring (16);

B) when nutrient solution needs to be heated during infusion, an infusion belt is hung on the hook (11), the placing plate (28) is pulled up by pulling the pulling block (32), then an infusion tube is placed into the left placing notch (27) on the placing frame (8) and enters the bottom of the placing frame (8), then the infusion tube passes through the space between two adjacent heating baffles (34), finally the infusion tube is led out from the right placing notch (27), the placing plate (28) is reset, the hand of a patient is placed in the placing groove (9), finally a medical worker inserts the needle of the infusion tube into the arm of the patient, and finally the control switch is turned on to heat the heating baffles (34), so that the nutrient solution in the infusion tube is heated, wherein the heating temperature is 3-5 ℃ lower than the temperature of a human body;

C) when the height of the placing frame (8) needs to rise, the positioning bolt is firstly loosened by using a wrench to separate the positioning bolt from the positioning sleeve (13), then the forward rotation rocker (14) enables the rotating screw (12) to rotate to drive the placing frame (8) to rise under the matching of the threaded hole (33), and after the rotating screw is driven to the rising position, the positioning bolt is reset, so that the misoperation that the rocker (14) drives the placing frame (8) to rise is avoided.
