Technical Field

[0002] At present, the hospital logistics systems in China are basically imported from abroad, and only a few large hospitals are equipped with hospital logistics systems. The high entry conditions and high technical content of pharmaceutical logistics, as well as the high professional requirements for information systems and logistics management, result in high costs.

Such hospital logistics systems can often only transport items on a single conveyor track and change tracks between two parallel conveyor tracks, usually by manual operation, with low work efficiency. In addition, the conveying mechanism of the existing elevator is often fixed, with a relatively light lifting weight, unable to complete the transportation and lifting of large-quality objects, nor can it complete the work of conveying and track-changing, and urgent improvement is needed.
