Adjustable Width Freezer Storage Containers

Abstract

The invention discloses a freezer storage container with adjustable width, which includes a box body, at least one freezer compartment and a box cover. The box body has two oppositely arranged first side walls, and two The telescopic wall and the bottom layer with telescopic function are connected to form a first cavity, the telescopic wall and the bottom layer are filled with absolute alcohol, and at least one second cavity and at least one third cavity are arranged in the first side wall Body, the second cavity is used to receive the absolute alcohol of the telescopic wall, and the third cavity is used to receive the absolute alcohol of the bottom layer; the freezer is placed in the first cavity; the lid is used to cover box. The present invention connects the two first side walls through the telescopic wall and the bottom layer with the telescopic function, so that the distance between the two first side walls can be adjusted, and then the space in which the first cavity can place the freezer compartment and the number of freezer compartments can be adjusted. , to match the needs of different clinical trials.

Description

technical field [0001] The invention belongs to the research field of cryopreservation of blood samples, and more particularly relates to a cryopreservation container with adjustable width. Background technique [0002] Drug clinical trials are to analyze the concentration of drugs or their metabolites in the blood to form a complete blood drug concentration-time curve, thereby reflecting the dynamic change laws of drug absorption, distribution, metabolism and excretion in the human body. In drug clinical trials, blood samples after centrifugation usually cannot be immediately sent to the analysis and testing center for detection and analysis. Therefore, it is necessary to put the centrifuged plasma or serum samples into cryopreservation tubes, and then place the cryopreservation tubes in an ultra-low temperature of minus 80°C. For storage in the environment, during the whole process of storage, it is necessary to ensure that the temperature of the stored samples is maintain...

AI Technical Summary

Problems solved by technology

After the plastic box is taken out of the ultra-low temperature refrigerator, it is easy to cause the frozen samples in the plastic box to redissolve or exceed the storage temperature stipulated in the test protocol, that is, overheating occurs. When the sample is overheated, it will affect the drug in the sample or its metabolism. The accuracy of product detection, especially in phase I clinical trials of drugs or drug bioequivalence trials, many samples need to be frozen at each sampling time point

The sample is placed in the plastic box for a long time, and the sample in the plastic box is prone to overheating when it is at room temperature for a long time, which affects the quality of the test

At present, the number of frozen specimens in the freezer box is fixed. Different clinical trials require different numbers of specimens to be frozen.
