[0002] Clinical trials refer to any systematic study of a drug on humans (patients or healthy volunteers) to confirm or reveal the effects, adverse reactions, and / or absorption, distribution, metabolism, and excretion of the test drug. The purpose is to determine the efficacy and safety of the test drug. Clinical trials are generally divided into Phase I, II, III, and IV clinical trials and EAP clinical trials. Clinical trials usually require blood, and blood sample transfer usually requires the use of turnover boxes for transportation. Currently, turnover boxes are prone to shaking or collision during the transportation of blood samples, causing damage.

[0003] Existing turnover boxes are usually opened by a hinged lid on the top or one side, and then the samples are placed directly in the sample loading structure. During the turnover transportation of blood samples, they are prone to shaking or collision and damage. In addition, when the top of the turnover box is fixed with a lock, the lock may be accidentally damaged by collision, which may easily cause the turnover box to open and cause the samples in the turnover box to fall and be damaged. Therefore, it is necessary to design a blood sample turnover box for clinical trials to solve the above problems. Utility Model Content
