Description

Technical Field

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

[0002] Amphibians have poor migration ability and high environmental dependence. They are indicator species of environmental health and green development globally. Currently, about one-third of amphibian populations are facing survival crises, and the global decline in the number of amphibians indicates that the global environment is deteriorating, which will pose a great threat to the survival of humans and other organisms. In addition to the negative effects of global climate change, habitat destruction and fragmentation, alien species invasion, environmental pollution, etc., diseases have become another key reason threatening the survival of amphibian species.

[0003] In recent years, the bacterial community in the skin microbiota of adult tailless amphibians has gained more recognition in mediating protection against various host pathogens. Skin symbiotic bacteria can inhibit the growth of Batrachochytrium dendrobatidis in vitro and can effectively reduce the harmful effects related to chytridiomycosis caused by Batrachochytrium dendrobatidis.

[0004] Conducting an investigation on chytridiomycosis in tailless amphibians in the northern foothills of the Qinling Mountains helps to strengthen the early warning and guiding role in the protection of tailless amphibian populations in the Qinling region, is conducive to early recognition of the ecological risks in this region, and formulating necessary management measures.

[0005] Studying and discussing the correlation between the diversity characteristics of the skin bacterial community of tailless amphibians in the northern foothills of the Qinling Mountains and chytridiomycosis and the environment is conducive to analyzing and predicting potential bacterial populations that can inhibit Batrachochytrium dendrobatidis, and helps to clarify the skin microbial ecology of amphibians. Through further research, the specific mechanism of the interaction among tailless amphibians - Batrachochytrium dendrobatidis - environment in the Qinling region can be clarified. These studies all have very important practical significance for protecting wild animals and ecological security in the Qinling region.

[0006] Currently, the specific method for collecting the skin tissue of amphibians is to hold the animal with high-density polyethylene gloves, put it into 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 skin tissue of the animal. However, when collecting multiple amphibians using the above technology, sample cross-contamination often occurs, affecting the later detection effect of the samples. Therefore, a skin sampling device convenient for collection and storage is proposed. Summary of the Invention

Inside the inner wall of the storage shell 18, there is a water pump. On the surface of the storage shell 18, there is a liquid inlet. Threadedly connected to the inner wall of the liquid inlet is a sealing plug;

[0046] On the surface of the second housing 2, there are a plurality of diversion cavities 19. Fixedly connected to the inner wall of the diversion cavity 19 is an intake fan 6.

One side of the limit sliding block is connected to the adjusting block 33. The swab paper is provided on the surface of the magic tape 35. Inside the second housing 2, there is a convex piece 23 fixedly connected.

[0049] Specifically, by rotating the first knob 5, the cover plate 4 is separated from the second housing 2. Then, the sealing plug is opened, and sterile water is added to the storage shell 18 through the liquid inlet. The staff places the animal on the convex piece 23 inside the second housing 2. Then, the cover plate 4 is installed inside the mounting opening. Through the water pump, the sterile water is delivered to the spray heads 32. The animal is washed through the spray heads 32. After the washing is completed, through the intake fan 6, the outside air enters the drying cover 20 through the diversion cavity, and the animal skin is dried through the air flow holes on the surface of the drying cover 20;

[0050] Finally, the electric telescopic rod 17 drives the substrate 31 to move downward, so that the swab paper on the surface of the magic tape 35 fits the animal. When the swab paper contacts the animal, the sponge 22 deforms under force, facilitating the swab paper to fit the surface of the animal. In addition, the adjusting block 33 squeezes the buffer spring, causing the adjusting block 33 to slide along the inner wall of the limiting chute through the limiting slider, realizing the adjustment of the height of the swab paper. The motor drives the mounting piece to rotate through the connecting shaft, and drives the swab paper to rotate through the mounting piece, the electric telescopic rod 17, the substrate 31, the buffer spring, the adjusting block 33, the sponge 22 and the magic tape 35, so as to collect samples on the surface of the animal skin.

[0051] Further, a processing shell 25 is provided inside the storage body 15. A plurality of filter nets 34 are provided on the inner wall of the processing shell 25. An activated carbon filter cotton 21 is provided on the inner surface of the processing shell 25. A telescopic pipe 14 is fixedly connected to the upper surface of the processing shell 25.

[0052] Both the telescopic pipe 14 and the drain pipe 11 are communicated with the processing shell 25, and the telescopic pipe 14 is communicated with the second housing 2.

[0053] Specifically, the nozzle 32 sprays sterile water, which flows into the processing shell 25 through the telescopic pipe 14, and then is filtered by the plurality of filter nets 34 and the activated carbon filter cotton 21. After the filtering process, it is discharged through the drain pipe 11. In addition, the dust-proof net 16 prevents external dust from entering the drain pipe 11.

[0054] Further, the lifting member includes a spring 38 and a lifting disc 36 fixedly connected to the end face of the spring 38;

[0055] The closing member includes a knob two 12 rotatably connected to the surface of the storage body 15 and a blocking plate 13 fixedly connected to the surface of the knob two 12.

[0056] Specifically, by rotating the knob two 12, the notch of the blocking plate 13 corresponds to the storage slot one 26 and the storage slot two 27. When a plurality of storage boxes 24 are sequentially placed into the storage slot one 26, the lifting disc 36 compresses the spring 38. After placement, rotate the knob two 12 again to make the blocking plate 13 press the storage box 24 to fix the storage box 24.

[0057] Further, the cooling component includes a cooling cavity 29 opened inside the storage body 15, a frame 40 fixedly connected inside the first housing 1, a semiconductor refrigeration sheet 37 fixedly connected inside the frame 40, and a heat dissipation fan 41 fixedly connected below the frame 40 inside;

[0058] The surface of the first housing 1 is provided with heat dissipation holes 10, and a diversion port 39 is provided inside the first housing 1. The diversion port 39 communicates with the frame 40;

[0059] Inside the storage body 15, a heat preservation ring 30 is provided to cooperate with the inside of the storage body 15. The heat preservation ring 30 is composed of heat preservation cotton.

[0060] Specifically, the temperature of the cooling cavity 29 is reduced by the cooling surface of the semiconductor refrigeration chip 37 to achieve low-temperature storage of the pcr test kit 28 inside the second storage tank 27. At the same time, the heat preservation ring 30 is combined to isolate the temperature, so that the storage box 24 inside the first storage tank 26 is in a normal temperature state. In addition, the heat generated by the heating surface of the semiconductor refrigeration chip 37 is dissipated through the heat dissipation holes 10 by the cooling fan 41, and then the outside gas enters the inside of the frame 40 through the diversion port 39.

[0061] Furthermore, an observation port is provided on the surface of the second housing 2. The inner wall of the observation port is fixedly connected with tempered glass 3. The bottom of the second housing 2 is fixedly connected with an iron ring. A groove is provided at the top of the first housing 1, and an electromagnet cooperating with the iron ring is provided on the inner wall of the groove. A sealing sheet is provided on the surface of the electromagnet. A base shell 7 is provided at the bottom of the first housing 1. A connection port is provided on the surface of the base shell 7, and a sealing plate 8 is threadedly connected to the inner wall of the connection port. A plurality of base strips 9 are fixedly connected to the surface of the sealing plate 8.

[0062] Specifically, it is convenient to observe the situation of the animals inside the second housing 2 through the tempered glass 3. The second housing 2 is connected to the first housing 1 through the magnetic connection of the electromagnet to the iron ring. The staff increases the friction area of the sealing plate 8 through the plurality of base strips 9, rotates the sealing plate 8, and thus separates it from the connection port, facilitating the removal of the swab paper from the base shell 7.

[0063] The working process of this application:

[0064] The staff wears high-density polyethylene gloves to hold the animal, rotates the first knob 5 to separate the cover plate 4 from the second housing 2, then opens the sealing plug and adds sterile water to the storage shell 18 through the liquid inlet. The staff places the animal on the convex piece 23 inside the second housing 2, and then installs the cover plate 4 inside the installation port. The sterile water is transported to the nozzle 32 through the water pump, and the animal is washed through the nozzle 32. After the washing is completed, the outside gas enters the air drying cover 20 through the diversion cavity by the intake fan 6, and the animal skin is air-dried through the air flow holes on the surface of the air drying cover 20. In addition, the sterile water sprayed by the nozzle 32 flows into the processing shell 25 through the telescopic pipe 14, and then is filtered through the plurality of filter meshes 34 and the activated carbon filter cotton 21. After the filtration process, it is discharged through the drain pipe 11. In addition, the dust-proof net 16 is used to prevent the outside dust from entering the drain pipe 11;

[0065] The electric telescopic rod 17 drives the substrate 31 to move downward, so that the swab paper on the surface of the magic tape 35 fits the animal. When the swab paper contacts the animal, the sponge 22 deforms under force, facilitating the swab paper to fit the surface of the animal. In addition, by the adjusting block 33 squeezing the buffer spring, the adjusting block 33 slides along the inner wall of the limit chute through the limit slider, realizing the adjustment of the height of the swab paper. The motor drives the mounting piece to rotate through the connecting shaft, and drives the swab paper to rotate through the mounting piece, the electric telescopic rod 17, the substrate 31, the buffer spring, the adjusting block 33, the sponge 22 and the magic tape 35, realizing the collection of samples on the surface of the animal skin. The swab paper is placed in the storage box 24, and there is 2 ml of DNA storage solution inside the storage box 24, while the skin tissue on the surface of the swab paper is placed inside the pcr detection kit 28.

[0066] The electromagnet is powered off from the iron ring, separating the second housing 2 from the first housing 1. By rotating the second knob 12, the notch of the baffle 13 corresponds to the first storage slot 26 and the second storage slot 27. When multiple storage boxes 24 are sequentially placed inside the first storage slot 26, the lifting plate 36 compresses the spring 38. After placement, the second knob 12 is rotated again to make the baffle 13 press the storage box 24 to fix the storage box 24. The steps of placing the pcr detection kit 28 into the second storage slot 27 are the same as the above steps for placing the storage box 24.

[0067] The temperature of the cooling cavity 29 is reduced by the cooling surface of the semiconductor refrigeration sheet 37, realizing the low-temperature storage of the pcr detection kit 28 inside the second storage slot 27. At the same time, the heat insulation ring 30 is combined to isolate the temperature, making the storage box 24 inside the first storage slot 26 in a normal temperature state. 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 outside gas enters the frame 40 through the diversion port 39.

[0068] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
