Description

Technical Field

[0001] The utility model relates to the technical field of wild animal epidemic source disease control, and in particular to a portable sampling device for animal diseased organ tissues. Background Art

[0002] Echinococcosis, also known as echinococcosis, is an infectious disease caused by the parasitism and transmission of Echinococcus tapeworms. It is also one of the parasitic diseases that my country is currently focusing on preventing and controlling. Livestock are important intermediate hosts of Echinococcus tapeworms. After Echinococcus tapeworms infect livestock, they can form echinococcosis cysts in the liver or lungs, resulting in cysts ranging from 3 to 15 cm. The cysts are filled with fluid and have high internal pressure. This cyst is the main pathological manifestation of echinococcosis. Molecular testing after sampling the contents or cyst wall of the cyst can determine whether there is Echinococcus tapeworm infection and identify the worm species.

[0003] At present, the difficulties faced in the sampling process of intermediate host echinococcosis cysts are: 1. The internal pressure of echinococcosis cysts is high. If the cyst wall is scratched, the internal fluid will splash or overflow in large quantities. If it touches the human mucosa, it may cause implantation and infection; 2. The internal fluid contains a large amount of substances that can be studied, which is difficult to recover after overflow, and it destroys the cyst structure, which is not conducive to subsequent experiments; 3. Some echinococcosis cysts are located deep in the tissues, and the external tissues need to be carefully dissected for sampling. If the dissection is improper, the internal cyst wall will rupture, making sampling difficult; 4. Echinococcus cysts are divided into outer cysts and inner cysts. The outer cysts are fibrotic tissues of the host, which are extremely tough and difficult to dissect, and molecular detection cannot be performed. It is necessary to deeply explore the inner cyst tissue or cyst contents, which makes sampling more difficult. Utility Model Content

[0004] In view of the defects in the prior art, the purpose of the utility model is to provide a portable sampling device for animal diseased organ tissue, which can safely and effectively obtain the inner capsule wall tissue and capsule contents for subsequent molecular detection experiments without damaging the cyst structure as much as possible.

[0005] The technical solution adopted by the utility model is: a portable sampling device for animal diseased organ tissue, comprising a sampling mechanism and a sample storage mechanism; the sampling mechanism comprises a sampling rod, the sampling rod comprises a threaded section and a sampling section arranged up and down, and the outer circumference of the sampling section is provided with a spirally arranged sampling groove; the sample storage mechanism comprises a sample storage tube, the upper end of the sample storage tube is provided with a threaded opening adapted to the thread of the sampling rod threaded section, and the lower end of the sample storage tube is provided with a sampling port for the sampling section to pass through.

[0006] The device provided by the technical solution uses a sampling mechanism and a sample storage mechanism to extract frozen lesion samples. After the sampling rod is inserted into the sample storage tube, the threaded sections cooperate with each other. When the sample storage tube is inserted into the sampling position, the sampling rod is rotated to retain the sample in the sampling groove, and the sampling rod is rotated in the opposite direction to place the sampling section in the sample storage tube. The sample is stored in the sample storage tube to prevent the sample from falling. During the entire operation, the inner capsule wall and contents can be obtained, ensuring the effectiveness of subsequent molecular experiments without causing splashing or overflow of the liquid in the capsule, while ensuring the overall structure of the cyst; it is convenient to operate and carry.

[0007] Preferably, an operating handle is provided at the upper end of the sampling rod corresponding to the threaded section.

[0008] Preferably, a drilling probe is provided at the lower end of the sampling section.

[0009] Preferably, the threaded section and the sampling section are arranged with equal length.

[0010] Preferably, an assembly section is provided at the upper end of the sample storage tube, and the threaded opening is arranged in the assembly section.

[0011] Preferably, the length of the sample storage tube is not less than the length of the sampling section.

[0012] The beneficial effects of the utility model are as follows: the utility model can perform sampling processing when the lesion sample is frozen, which can avoid splashing or overflowing of the liquid in the cyst, and the overall structure of the echinococcosis cyst is guaranteed through the integral sampling. When in use, the sample can be deeply probed into the lesion tissue structure, and the inner cyst wall and contents can be obtained, thereby ensuring the effectiveness of subsequent molecular experiments; the overall operation is convenient, easy to carry, and has high practical value.

[0017] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0018] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0019] like Figure 1 and Figure 2 As shown, a specific embodiment of the utility model provides a portable sampling device for animal diseased organ tissue, which can be used for fast and accurate sampling operations, and specifically includes a sampling mechanism and a sample storage mechanism; the sampling mechanism includes a sampling rod 100, the sampling rod 100 includes a threaded section 110 and a sampling section 120 arranged up and down, and the outer periphery of the sampling section 120 is provided with a spirally arranged sampling groove 130; the sample storage mechanism includes a sample storage tube 200, the upper end of the sample storage tube 200 is provided with a threaded opening 210 that is threadably matched with the threaded section 110 of the sampling rod 100, and the lower end of the sample storage tube 200 is provided with a sampling port 220 for the sampling section 120 to pass through.

[0020] like Figure 1 and Figure 2 As shown, through the above arrangement, in this embodiment, a sampling mechanism and a sample storage mechanism are used in combination to extract frozen lesion samples. The sampling rod 100 can be inserted into the sample storage tube 200, and the threaded section 110 and the threaded opening 210 form a threaded fit, so that the sampling rod 100 and the sample storage tube 200 can move relative axially when rotating. When the sample storage tube 200 of the assembled sampling rod 100 is inserted into the sampling position, the sample is retained in the sampling groove 130 by rotating the sampling rod 100, and the sampling rod 100 is rotated in the opposite direction so that the sampling section 120 is located in the sample storage tube 200 to prevent the sample from falling off. During the entire operation, the inner capsule wall and contents can be obtained, thereby ensuring the effectiveness of subsequent molecular experiments and preventing the liquid in the capsule from splashing or overflowing, while ensuring the overall structure of the cyst; it is convenient to operate and also easy to carry.

[0021] As before, when performing the sampling operation, the sampling rod 100 needs to be rotated in different directions successively. In this embodiment, an operating handle 140 is provided at the upper end of the sampling rod 100 corresponding to the threaded section 110. The provision of the operating handle 140 makes it more convenient to rotate the sampling rod 100, which saves time and effort.

[0022] like Figure 1 and Figure 2 As shown, when performing the sampling operation, the sampling rod 100 needs to be rotated so that the sampling section 120 is drilled into the frozen sample. In this embodiment, a drilling probe 150 is provided at the lower end of the sampling section 120, so that the sampling section 120 can be smoothly screwed into the sample completely. In practical applications, the threaded section 110 and the sampling section 120 are arranged in equal length. The length of the sample storage tube 200 is not less than the length of the sampling section 120. In this way, when the threaded section 110 is completely screwed into the threaded opening 210, the sampling section 120 can completely pass through the front end of the sample storage tube 200. When the threaded section 110 exits the threaded opening 210, the sampling section 120 is completely located in the sample storage tube 200, and the sample is placed to fall from the sampling slot 130. In this embodiment, the lengths of the threaded section 110, the sampling section 120 and the sample storage tube 200 are preferably set to 6 cm.

[0023] like Figure 1 and Figure 2 As shown, in order to ensure that the sample storage tube 200 and the sampling rod 100 are accurately matched, this embodiment provides an assembly section 230 at the upper end of the sample storage tube 200, and the threaded opening 210 is arranged in the assembly section 230. When the sampling rod 100 is inserted into the sample storage tube 200, the assembly section 230 and the threaded section 110 are stably matched.

[0024] like Figure 1 and Figure 2 As shown, when the device is in use, the specific use process is as follows;

[0025] (1) Before sampling, the diseased organ tissue of the animal is first frozen to keep the entire tissue in a fixed state;

[0026] (2) Insert the sampling rod into the sample storage tube;

[0027] (3) placing the drilling probe of the sampling rod at the lesion tissue;

[0028] (4) Hold the operating handle and turn it downward to gradually screw the drilling probe into the tissue, and the sample tissue is collected in the sample storage tube;

[0029] (5) Rotate the sampling rod to remove it from the sample storage tube, and use tweezers to remove the tissue in the sample storage container for subsequent experiments;

[0030] (7) After sampling, the lesion tissue is returned to the refrigerator for freezing.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
