Description

Technical Field

[0001] The present invention relates to the technical field of sample collection, and in particular to a skin sampling device that is convenient for collection and storage. Background Art

[0002] Amphibians have poor migration ability and high dependence on the environment. They are indicator species of environmental health and green development worldwide. Currently, about one-third of amphibian populations are facing survival crisis. The sharp decline in the number of amphibians worldwide indicates that the global environment is deteriorating, which will pose a great threat to the survival of humans and other organisms. In addition to negative effects such as global climate change, habitat destruction and fragmentation, invasion of alien species, and environmental pollution, diseases have become another key reason threatening the survival of amphibian species. The role of bacterial communities in the skin microbiota of adult anuran amphibians in mediating protection against a variety of host pathogens has been increasingly recognized in recent years, with skin commensal bacteria inhibiting the growth of B. dendrobatidis in vitro and being effective in reducing the deleterious effects associated with chytridiomycosis caused by B. dendrobatidis. The investigation of chytridiomycosis in anurans in the northern foothills of the Qinling Mountains will help strengthen the early warning and guidance of anuran amphibian population protection in the Qinling Mountains, and will help to recognize the ecological risks in the region as early as possible and formulate necessary management measures. The study explored the correlation between the diversity characteristics of the skin bacterial community of anuran amphibians in the northern foothills of the Qinling Mountains and chytridiomycosis and the environment, which is conducive to the analysis and prediction of potential bacterial populations that inhibit frog chytrid fungus and helps to clarify the ecology of amphibian skin microorganisms. Through further research, the specific mechanism of the interaction between anuran amphibians, frog chytrid fungus and the environment in the Qinling Mountains can be clarified. These studies are of great practical significance for protecting wildlife and ecological security in the Qinling Mountains. Currently, the specific method for collecting amphibian skin tissue is to grab the animal with high-density polyethylene gloves, put it in a box, pour 100 ml of sterile water to remove surface dirt and transient bacteria, and then wipe the skin with a skin swab to collect the animal skin tissue. However, the above technology often causes sample crossover when collecting multiple amphibians, affecting the effect of later sample detection. Therefore, a skin sampling device that is convenient for collection and storage is proposed. Summary of the invention

At the same time, the temperature is isolated by combining with the insulation ring 30, so that the storage box 24 inside the storage slot 1 26 is at room temperature. In addition, the heat generated by the heating surface of the semiconductor refrigeration sheet 37 is dissipated through the heat dissipation holes 10 by the heat dissipation fan 41, and then the external gas enters the frame 40 through the guide port 39.

[0031] The workflow of this application: The staff member wearing high-density polyethylene gloves grasps the animal, turns the knob 15 to separate the cover plate 4 from the shell 22, then opens the sealing plug to add sterile water to the storage shell 18 through the liquid inlet, and the staff member places the animal on the convex piece 23 inside the shell 22, and then installs the cover plate 4 inside the installation port, and transports the sterile water to the nozzle 32 through the water pump, and washes the animal through the nozzle 32.

In addition, the nozzle 32 sprays sterile water, which flows into the inside of the processing shell 25 through the telescopic tube 14, and then is filtered through multiple filter screens 34 and activated carbon filter cotton 21. After filtering, it is discharged through the drain pipe 11. In addition, the dustproof net 16 is used to prevent external dust from entering the drain pipe 11; The electric telescopic rod 17 drives the base plate 31 to move downward, so that the swab paper on the surface of the Velcro 35 fits the animal. When the swab paper contacts the animal, the sponge 22 is deformed by force, which makes it easier for the swab paper to fit the surface of the animal. In addition, the adjusting block 33 squeezes the buffer spring, so that the adjusting block 33 slides on the inner wall of the limiting slide groove through the limiting slider to adjust the height of the swab paper.

The swab paper is placed in the storage box 24, and there is 2ml of liquid inside the storage box 24. DNA storage liquid, and the skin tissue on the surface of the swab paper is placed inside the PCR detection kit 28, and the electromagnet is de-energized from the iron ring to separate the shell 2 2 from the shell 1 1, and the notch of the blocking plate 13 is made to correspond to the storage slot 1 26 and the storage slot 2 27 by turning the knob 2 12. When multiple storage boxes 24 are placed inside the storage slot 1 26 in sequence, the spring 38 is compressed by the lifting plate 36. After placement, the knob 2 12 is turned again to make the blocking plate 13 press the storage box 24 to fix the storage box 24. The step of placing the PCR detection kit 28 into the storage slot 2 27 is consistent with the above-mentioned storage box 24 placement step; The temperature of the cooling chamber 29 is lowered by the cooling surface of the semiconductor refrigeration plate 37, so that the PCR detection kit 28 inside the storage slot 27 can be stored at low temperature. At the same time, the temperature is isolated by combining with the insulation ring 30, so that the storage box 24 inside the storage slot 1 26 is at room temperature. In addition, the heat generated by the heating surface of the semiconductor refrigeration plate 37 is dissipated through the heat dissipation hole 10 by the heat dissipation fan 41, and then the external gas enters the frame 40 through the guide port 39.
