[0002] In the medical field, the proper storage of medicines is of vital importance. Traditional refrigerated medicine boxes have many limitations in actual use. On the one hand, when medicines need to be transferred from the pharmacy to the operating room or other locations, due to the lack of precise temperature control methods, the temperature inside the medicine box is easily affected by changes in the external environment, making it difficult to ensure that the medicines are always within the ideal storage temperature range. Especially during the process of moving or in outdoor conditions, the temperature fluctuates greatly, which cannot meet the storage needs of some medicines with strict temperature requirements. This may not only affect the quality and effectiveness of the medicines, but also pose a potential risk to the patient's treatment effect. Therefore, there is an urgent need for a refrigerated medicine box with precise temperature control function to ensure that medicines can be reliably stored in various usage scenarios.

[0003] Therefore, there is an urgent need for a better refrigerated medicine box with controlled internal temperature on the market. Utility Model Content
