Description

Technical Field

[0001] This utility model is mainly aimed at the fields of blood products, biological products and special items that require cold chain storage, transportation and transfer, and belongs to the field of cold chain storage and transportation technology, specifically involving a drag-and-drop cold chain storage and transportation box. Background Technology

[0002] After blood is collected, the blood bank undertakes a series of transportation, handling, and processing procedures. When a hospital needs blood, it submits a blood request, and the blood bank then transports the blood to the hospital through a series of transfers. Traditionally, blood (including whole blood and plasma) is transported and handled manually during these processes, which is labor-intensive, and cold chain management is not standardized, posing risks of contamination and cold chain disruption. Furthermore, because the return time from external blood collection is unpredictable and the blood cannot be stored at room temperature, the blood component department must have staff on duty every day until all the blood from the external collection department has returned before they can leave work.

[0003] To systematize cold chain management, reduce labor intensity, and improve work efficiency, as well as to ensure safer, more standardized, and more convenient storage and transportation of blood and blood products, this utility model provides a technical solution for a drag-and-drop cold chain storage and transportation box.

[0004] The technical solution provided by this utility model, compared with the traditional manual batch handling, firstly complies with the blood transportation standards of the National Health Commission; secondly, it saves human resources, eliminates the need for multiple people to handle in batches, ensures that the blood temperature remains constant during transportation, and avoids risks such as drop and damage during transportation.
