Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated management of blood products, in particular to a handheld adjustable antenna freezer inventory device based on RFID technology. Background Art

[0002] Blood products need to be refrigerated and stored in hospital institutions, usually in refrigerators, freezers and other freezer equipment. The management of blood products is strict and requires regular inventory. With the popularization of RFID technology in the field of blood product management, RFID handheld inventory devices are widely used in the refrigerated inventory of blood products.

[0003] Currently, the common RFID handheld inventory device has a fixed vertical structure with a screen and an RFID antenna, and the handle is directly below the screen, which is suitable for inventory operations in most open environments. When conducting an inventory of blood product freezers, generally, after the operator opens the refrigerator, pulls out the drawer storing the blood products, uses the RFID handheld inventory device for inventory, and then pushes the drawer of the blood products back. In the case of freezer storage, it is necessary to move out the storage rack for the upper-layer blood products to inventory the blood products in the lower layer. Since the blood products are heavy and the operators are usually female, the operation is difficult and the efficiency is low. At the same time, the long opening time causes the temperature inside the freezer to rise, which is not conducive to the storage of blood products. Summary of the Utility Model
