Description

Storage box

Technical Field

The invention relates to the technical field of medical instruments, in particular to a storage box.

Background

The clinical test of the medicine refers to any systematic research of the medicine on human bodies (patients or healthy volunteers), and is vital to the temperature monitoring of the test medicine in the whole process of the clinical test of the medicine, and each clinical test of the medicine needs to record the temperature of the test medicine in the processes of transportation, transportation and storage in detail, so that the environment where the test medicine is located is always in the specified temperature range, and the safety, the stability and the effectiveness of the medicine are ensured. Particularly, test drugs (such as insulin glargine injection, adalimumab, infliximab and the like) stored at low temperature always need to be placed in an environment with the temperature of 2-8 ℃.

At present, a lot of test medicines form centralized management, so the tests are uniformly placed in a central pharmacy of a clinical drug testing institution, when the test medicine is used, a researcher takes the test medicines from the central pharmacy and transfers the test medicines to a department to use the test medicines for a subject, and the common method is to firstly place the medicines in an insulation box or a foam box with an insulation effect and then place a plurality of ice blocks or ice bags in the medicines and the insulation box. The ice blocks in the incubator are too few, and because the transport distance is long, particularly in hot summer in the south, the outdoor temperature is high, and the test drugs in the incubator easily exceed the specified storage temperature of the drugs; the ice blocks in the incubator are too much, and the test drugs contact the ice blocks, so that the temperature of the drugs is lower than the specified storage temperature of the drugs, and the phenomenon of drug overtemperature occurs. According to the regulation of the clinical trial administration of the medicine, once the medicine is over-temperature, the medicine can not be delivered to the testee for use, and the testee participating in the clinical trial of the medicine can not take the medicine on time, thus seriously affecting the clinical trial process.
