Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to an infusion stand and an infusion cart. Background Technology

[0002] An IV stand is a support device used in hospitals to administer intravenous fluids to patients. When in use, the IV bag is hung directly on the hook on the IV stand, and the liquid in the IV bag flows into the patient's body from top to bottom.

[0003] In some special circumstances, such as during influenza outbreaks, hospitals receive a large number of patients requiring intravenous infusions. The number and placement of IV stands cannot meet the demand, and some patients have even resorted to using clotheslines as IV stands.

[0004] However, when using a clothesline as an IV stand, the accompanying person needs to hold the clothesline in their hand the whole time, which is both troublesome and strenuous. Utility Model Content

[0030] Compared to existing technologies, this new method uses a connecting device to lock the IV pole to the object being connected, thus securing the IV pole and ensuring it remains vertical. This avoids the need to hold the IV pole during infusion, freeing the hands of the accompanying person. The connecting device can be connected to both a horizontal and a vertical bar to adapt to different environments, with the horizontal and vertical bars representing one type of object to be connected.

[0031] Therefore, this application has the characteristics of reasonable structure and convenient use. Attached Figure Description
