Short medical staff need to stand on tiptoe to operate during the dressing change process. Patients need to hold the infusion bottle or carry the infusion stand when walking, which is very inconvenient. With the continuous improvement of medical standards, the functionality of traditional infusion stands has been improved. The infusion stand in the existing technology generally includes a hook, a sleeve, a base and casters, wherein the sleeve can be set as a manually controlled or electrically retractable structure.

[0003] For example, the utility model patent CN210673913U with the authorization announcement date of June 5, 2020 discloses a foldable electric infusion stand, including a base, an electric telescopic rod, a top seat and a folding hook assembly, wherein the electric telescopic rod includes a fixed part and a telescopic part, the fixed part is vertically mounted on the base, and the telescopic part is embedded in the upper end of the fixed part. When the electric telescopic rod is powered on, the telescopic part can be retracted into or extended from the fixed part. Another example is the utility model patent CN219579578U with the authorization announcement date of August 25, 2023 discloses an electric infusion stand, including an electrically controlled telescopic rod. Although this type of electric telescopic structure realizes electric adjustment of the height of the infusion stand through electric adjustment, the existing electric telescopic control speed is generally fixed, which makes it difficult to make fine and precise adjustments, or in other words, the inability to freely control the lifting speed during adjustment leads to excessive lifting when positioning to a certain precise position, and repeated upward and downward operations are required to accurately position the position.

[0004] On the other hand, although the infusion stand in the prior art has a related mechanism for supporting the elbow, as described in the utility model patent CN219579578U, the supporting assembly includes a lifting component, a supporting component and a supporting component for supporting the mobile phone, and the lifting component is arranged on the outer wall of the electric telescopic rod. Through the above method, it can be known that the utility model can support the patient's arm when the patient goes out to the toilet or breathes fresh air. However, its adjustment requires the adjustment of two knobs, which is more troublesome to operate, and the position of the supporting plate is fixed, and the angle cannot be adjusted according to the user's posture, which is not a good experience.
