Problems solved by technology

[0002] Existing preventive medicine often needs to collect virus samples, and store virus samples in the device through the sample storage device. Some viruses need to be stored at low temperature or even ultra-low temperature environment, and the sample storage device is usually greatly affected by the external environment temperature. If it is controlled, it will easily damage the sample structure, especially when carrying and transferring, even the bumps generated during the transfer process will damage the sample structure, thus losing the significance of sampling

Embodiment 1

[0021] Embodiment 1, the liquid nitrogen tank 5 is communicated with the refrigeration pipe 11 through the control valve 4, a mounting seat 61 is provided on one side of the box body 10, the liquid nitrogen tank 5 is fixedly connected with the mounting seat 61 through threads, and the protective cover 6 is hinged with the mounting seat 61. , the liquid nitrogen tank 5 is isolated by the protective cover 6 to avoid accidental contact with the liquid nitrogen tank 5 from frostbite to the operator.

[0022] Specifically, the lower side of the mounting seat 61 is provided with an ejector pin 41 , the control valve 4 includes a valve core 42 , a compression spring 44 and a spring seat 43 , the ejector pin 41 is abutted against the valve core 42 , and a side wall of the ejector pin 41 is provided with a connection with the refrigeration pipe 11 . Through hole, the valve core 42 is slidably connected with the spring seat 43 through the guide rod, the compression spring 44 is arranged ...

Embodiment 2

[0027] In the second embodiment, the support spring 83 can also be replaced with a rubber column, which is flexibly connected to the housing 81 and the base 85 .

Embodiment 3

[0028] In the third embodiment, the support spring 83 can also be replaced with an air spring, so that the movable stroke between the casing 81 and the base 85 is increased, and more vibration energy is absorbed.

[0029] In this embodiment, the box body 10 is provided with a thermal insulation layer 9, which can quickly cool with the liquid nitrogen tank 5, and at the same time ensures a stable temperature, which is convenient for virus samples to be stored. 2. Avoid turbulent damage to the sample vial 2 during the transfer process, resulting in the leakage of the virus sample.

Abstract

The invention relates to the technical field of virus sample preservation, in particular to a virus sample preservation device for the preventive medicine. The device comprises a box body and a sealing cover hinged to the upper side of the box body, a heat preservation layer is arranged on the side wall of the box body, a refrigeration pipe is arranged at the inner side of the box body, a liquid nitrogen tank is arranged at one side of the box body, and a control valve is arranged on the liquid nitrogen tank. A protective cover is arranged at the outer side of the liquid nitrogen tank, a support is arranged at the inner side of the box body, a sample bottle is arranged in the support, a balance seat is arranged at the bottom of the support and comprises a shell, a piston, a supporting spring and a base, a hydraulic cylinder matched with the piston is arranged in the base, and the base is fixedly connected with the box body. The heat preservation layer is arranged in the box body and matched with the liquid nitrogen tank for rapid refrigeration, meanwhile, the temperature stability is guaranteed, virus samples are convenient to preserve, meanwhile, the balance seat supports the support and is matched with protection cotton to protect the sample bottle, and the situation that the sample bottle is damaged due to bumping in the transferring process, and virus sample leakage is caused is avoided.

Description

technical field [0001] The invention relates to the technical field of virus sample preservation, in particular to a virus sample preservation device for preventive medicine. Background technique [0002] Existing preventive medicine often needs to collect virus samples, and store the virus samples in the sample storage device through the sample storage device. Some viruses need to be stored in a low temperature or even ultra-low temperature environment. The sample storage device is usually greatly affected by the temperature of the external environment. It is easy to damage the sample structure with control, especially when carrying out the transfer, and even the bumps generated during the transfer process can damage the sample structure, thus losing the meaning of sampling. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose a virus sample storage device for preventive medicine in order to solve the shortcomings in the prior art. [0004...
