Description

Technical Field

[0001] The utility model relates to the technical field of an automated system for storing biological samples, in particular to a low-temperature docking and transfer device for biological samples. Background Art

[0002] Low-temperature docking and transfer devices for biological samples are common and important equipment in scientific research, medical diagnosis, biopharmaceuticals and other fields. They are used to efficiently and accurately transfer biological samples from one container or device to another in a low-temperature environment. The preservation of biological samples such as cells, tissues, and serum is crucial for many experiments and medical diagnoses, and the low-temperature environment helps slow down the metabolic process of biological samples and maintain their activity and integrity.

[0003] When storing biological samples, a stable low-temperature environment is required to keep the samples active. However, currently, the loading and unloading and transfer of samples are generally carried out at room temperature, which has a great impact on the activity of the samples. In addition, the transfer and loading and unloading of sample tubes or boxes are usually carried out manually, which greatly affects the efficiency of loading and unloading, reduces production capacity, and is inconvenient to use. Therefore, a low-temperature docking and transfer device for biological samples is proposed.

[0004] A low-temperature docking and transfer mechanism for biological samples disclosed in the announcement number CN218968152U includes: a shell, a test tube rack grasping mechanism, an external operation seat for feeding and discharging materials, a test tube rack pick-up and placement bin, an insulated partition door for opening and closing the internal port of the external operation seat, and a sealed insulated door for opening and closing the external port of the external operation seat. Through the above method, the low-temperature docking and transfer mechanism for biological samples of the utility model can not only dock with external manual or automated equipment through the external operation seat and provide a low-temperature cache environment that can ensure the activity of the sample, but also carry out the handling and transfer of biological samples, effectively improving the accuracy, stability and work efficiency of the docking and transfer operation.

[0005] Although the above patent can not only dock with external manual or automated equipment through the external operation seat and provide a low-temperature cache environment that can ensure the activity of samples, but also carry and transfer biological samples, effectively improving the accuracy, stability and work efficiency of docking and transfer operations; however, the device lacks the function of fixing sample racks of different sizes. During the sample transportation process, the sample rack is prone to shaking or tilting due to loose fixation, which may cause the sample to fall and be damaged.

[0006] Therefore, it is necessary to invent a low-temperature docking and transfer device for biological samples to solve the above problems. Utility Model Content
