Description

Technical Field

[0001] The utility model relates to the technical field of drug preparation, in particular to a liquid transfer device. Background Art

[0002] During the preparation of drugs, liquids such as alkali solution are required. These liquids are generally loaded into rectangular barrels. In order to continuously supply liquids, a pump is usually placed on the barrel. If the liquid in the barrel is insufficient, the liquid is re-injected to ensure sufficient supply. However, when injecting liquid, the injection port is at a high height, which brings many inconveniences to the injection operation, and the liquid is easily contaminated during the injection process. At the same time, this rectangular barrel is difficult to transfer due to its large size. In addition, in order to save production space, the barrel is placed in a relatively small position, which also causes trouble for the injection of liquid. Secondly, since the pump placed on the barrel is not fixed, it is easy to shake when pumping liquid, which in turn produces a lot of noise. Utility Model Content
