Furthermore, in the medical infusion support, the fixing seat 4 is provided with the following structure for guiding the infusion tube 17 to pass through, so that after the inclined arm 5 rotates along with the weight arm 6, the end part of the inclined arm 5 can squeeze the infusion tube 17, and based on the above purpose of the fixing seat 4, the following structure is preferably adopted:

as shown in fig. 3 and 5, the clamping seat 4 comprises a fixing plate 16 fixed on the side wall of the upright post 2, and a clamping groove 15 is respectively arranged at the upper end and the lower end of the fixing plate 16; after the infusion tube 17 is clamped and fixed by the two clamping grooves 15, the infusion tube 17 positioned between the two clamping grooves 15 is abutted against the front side of the fixed plate 16.

Furthermore, in order to make the bell-shaped end 8 generate a louder warning sound when being impacted by the balance weight 7, the bell-shaped end 8 should be made of hard metal and has a bell-shaped shell shape.

Furthermore, in the medical infusion support, the components such as the weighing beam, the hinge shaft 13, the balance weight 7, the weight scale 14, the hook 11 and the like actually form a metering part, and the working accuracy of the medical infusion support directly influences the clinical use effect of the medical infusion support; it is clear that the accuracy of the above-mentioned metering section in operation is greatly affected by whether the upright 2 remains vertical or not; in order to facilitate judging whether the upright post 2 is in the vertical direction, the invention is also provided with the following technical improvements:

as shown in fig. 1 and 6, a vertical measuring instrument 3 is arranged on the upright post 2, the vertical measuring instrument 3 is in a sleeve-shaped shell structure, the sleeve-shaped shell structure is fixedly sleeved outside the upright post 2, liquid is encapsulated in an inner cavity of the vertical measuring instrument 3, the outer side wall of the vertical measuring instrument 3 is transparent, and a plurality of same scale strips 20 are arranged on the periphery of the outer side wall; therefore, by comparing the corresponding values of the liquid level in different scale bars 20, whether the upright post 2 is in the vertical direction or not can be judged, and the inclined direction of the upright post 2 can be judged, so that the placement of the medical infusion support can be quickly adjusted.

Furthermore, in order to more conveniently adjust the placement of the medical infusion support, so that the upright post 2 keeps in the vertical direction, and the working accuracy of the metering part is improved, the invention also has the following improvement:
