Description

A biological sample refrigerated transport box

technical field

The utility model relates to a refrigerated transport box, specifically a biological sample refrigerated transport box, which is used for the refrigerated transport of biological samples with higher temperature requirements in the fields of biology and medicine, and is especially suitable for tissues such as placenta for the purpose of obtaining stem cells Shipping of samples.

Background technique

At present, in the field of biomedicine, some samples or drugs have extremely strict temperature requirements. For example, vaccines, blood samples, and biological tissue samples need to be kept at refrigerated temperature or normal temperature during transportation. Generally, refrigeration requires 4-8°C, and normal temperature requires 4 -25°C.

At present, refrigerated trucks are generally used for long-distance and large-scale transportation of the above-mentioned samples to ensure cold chain supply. However, refrigerated trucks cannot be used for short-distance, small transportation volume, and scattered destinations of samples. Currently, refrigerators (also known as vaccine boxes) are generally used for transportation. The general practice is to place a cooling agent in the refrigerator to ensure that the temperature in the refrigerator meets the requirements. Some refrigerators are also equipped with a temperature detection system.

However, due to the limited cold storage capacity of the cold storage agent in the refrigerator, the time for the refrigerator to ensure that the temperature meets the requirements is also limited. This kind of refrigerator can only ensure the refrigerated transportation under the condition of urban transportation. Generally, this kind of refrigerator The transportation storage time shall not exceed 8 hours.

There is another vehicle-mounted active biological refrigerator that can transport samples in small quantities for a long time, but this transportation method is suitable for the transportation of expensive and rare samples, not common samples.

At present, such as cord blood banks, biological sample banks, etc., many sample collection locations are scattered and relatively far away, and the transportation time generally exceeds 12 hours, or even 24 hours. In such cases, if the traditional refrigerated transport box is used, the temperature will exceed the control range. Moreover, during the sample transportation process, the internal temperature of the transportation vehicle may exceed the limited temperature, which further increases the uncontrollability of the transportation process. Due to the limitations of cold storage agents such as ice bricks, the method of increasing the number of ice bricks cannot overcome the above limitations, and switching to ultra-low temperature refrigerants such as dry ice may cause the temperature of the sample to be too low.

In short, the current refrigerated transport boxes have the following technical difficulties:

1. The temperature of the sample is the result of the natural transfer of the cooling agent, and the temperature cannot be controlled.

2. The cold storage agent such as ice bricks placed in the refrigerator is limited, and the time that the refrigerator can keep the samples is limited, and the transportation time cannot be guaranteed if the transportation time is 12 hours or even longer.

3. If dry ice and other cooling agents are used, the sample temperature will continue to decrease, and the temperature will be lower than the sample temperature requirement.

4. The current refrigerated boxes cannot transport samples in low-temperature areas. In some areas, if no cooling agent is placed in the box, the temperature of the samples will appear low temperature, and blood and tissue samples are very sensitive to low temperatures.

There are inventions on the market that optimize and improve refrigerators. For example, the Chinese invention patent with application number 201310196035.2 discloses an incubator. The heat preservation efficiency of the incubator is improved by optimizing the design of cold storage plates, but it does not fundamentally overcome the above-mentioned problems. defect.

Application No. 201610138611.1 Chinese invention patent discloses a multi-functional refrigerator, which is powered by batteries to improve the battery life of the refrigerator, but electric cooling requires a large battery power, which limits the battery life.
