Description

Technical Field

[0001] This invention relates to the field of animal husbandry and veterinary experimental technology, and in particular to a sampling and testing device for animal husbandry and veterinary laboratories. Background Technology

[0002] In animal husbandry and veterinary laboratory testing, the accuracy and convenience of sample collection directly affect the reliability of test results. Animal body fluids, tissues and other samples commonly used for testing need to be collected and processed quickly and without contamination. In most cases, tissue samples need to be taken from the animal's oral cavity during laboratory testing.

[0003] Currently, most laboratory tests involve manually scraping tissue from the animal's mouth using a scraper or cotton swab. This method carries the risk of accidental bites or scratches to the operator's fingers, and is relatively rudimentary. Furthermore, traditional sampling and testing devices are often single-function designs, with sampling and scraping processes independent of each other. Additional tools are needed to transfer the sample, making the process cumbersome, inefficient, and lacking in precision. Human error can easily lead to uneven sample volume or secondary contamination, affecting the accuracy of subsequent test data. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a sampling and testing device for animal husbandry and veterinary laboratories. It is an integrated device that integrates sampling and scraping functions, and is flexible in adjustment and highly adaptable.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sampling and testing device for animal husbandry and veterinary laboratory use includes a housing, an adjustment component is provided inside the upper section of the housing, a sampling component is provided inside the lower section of the housing, and a scraping component is snapped into the bottom of the housing.

[0007] The adjustment assembly includes two racks fixedly connected to the inner walls of the outer shell on opposite sides, a loading plate disposed inside the upper section of the outer shell, and two support columns fixedly connected to the upper side of the loading plate near the two racks. Each of the two support columns has an inner compartment on its opposite side. A gear is rotatably connected to the middle of the inner compartment. A fixing column is fixedly connected to the upper rear side of the right end of the loading plate. A rod is fixedly connected to the upper front side of the right section of the loading plate. A gear is rotatably connected to the rear top of the rod.

[0008] Gear 2 is fixedly connected to the front middle of gear 1 on the upper side of the loading plate near the fixed column, and pulley 1 is fixedly connected to the rear middle of gear 3. Pulley 2 is fixedly connected to the front middle of gear 1 on the upper side of the loading plate away from the fixed column.

[0009] A motor is fixedly connected to the upper end of the fixed column. The output end of the motor is fixedly connected to the middle rear side of gear one on the upper side of the loading plate near one end of the fixed column. The outer wall of gear two meshes with the outer wall of gear three. The outer wall of pulley one is connected to the outer wall of pulley two by a synchronous belt.

[0010] The motor and gear 2 are both located outside one of the support columns, and pulley 2 is located outside the other support column. The outer walls of the two gears 1 respectively mesh with the adjacent sides of the two racks.

[0011] The same buffer plate is fixedly connected to the upper side of both support columns. An anti-slip grip column is fixedly connected to the upper inner wall of the outer shell. An anti-detachment ring is fixedly connected to the lower inner wall of the outer shell. Four sliding grooves are evenly opened on the inner wall of the outer shell. The four corners of the loading plate are slidably connected to the inner walls of the four sliding grooves respectively.

[0012] The sampling assembly includes a telescopic rod fixedly connected to the lower side of the middle of the loading plate and a motor fixedly connected to the lower side of one end of the loading plate. The output end of the motor is fixedly connected to a threaded rod, and the bottom end of the telescopic rod is fixedly connected to a piston. A sampling cylinder is sleeved on the outside of the piston.

[0013] The upper and lower outer walls of the sampling cylinder are both fixedly connected to threaded sleeves on the same side. The middle of the two threaded sleeves is threaded to the outer wall of the threaded rod. The middle of the lower end of the sampling cylinder is fixedly connected to a sampling tube. The lower end of the threaded rod is fixedly connected to an anti-detachment block.

[0014] The scraping assembly includes a container shell snapped onto the lower side of the outer shell and a motor fixedly connected to the middle of the inner wall of the lower side of the container shell. The output end of the motor is fixedly connected to a hollow column. A slot is opened through one side of the outer wall of the hollow column, and a through hole is opened through the upper side of the hollow column.

[0015] A scraper is fixedly connected to the middle of the inner wall of the slot, and a scraping port is opened through one side of the outer wall of the container. The end of the scraper away from the hollow column is located inside the scraping port.

[0016] The inner wall of the container is fixedly connected to a sealing plate, the motor is located on the lower side of the sealing plate, the hollow column and the scraper are both located on the upper side of the sealing plate, and the scraping port is located on the upper side of the sealing plate.

[0017] This device achieves precise adjustment, quantitative sampling, and efficient scraping of animal oral tissue and body fluid samples through the coordinated operation of adjustment, sampling, and scraping components. The core of the device revolves around power transmission and multi-process adaptation. The operator holds the non-slip grip column and inserts the scraping component into the mouth of the animal to be sampled. The side of the container with the scraping opening is attached to the cheek wall of the animal's mouth. The motor starts and drives the hollow column to rotate back and forth, which drives the scraper in the slot to rotate synchronously. During the rotation of the scraper, the tissue sample on the cheek wall of the animal's mouth can be scraped. The sample flows along the scraper and into the hollow column through the slot for subsequent detection and analysis.

[0018] The present invention has the following beneficial effects:

[0019] In this invention, the outer shell, adjustment components, sampling components, anti-detachment ring, anti-slip grip column, and sliding groove work together to alleviate the problems of current laboratory testing methods that often involve manual sampling of tissues from animal mouths by laboratory personnel holding a scraper or cotton swab and inserting it into the animal's mouth. This method may result in laboratory personnel's fingers being too close to the animal's mouth, leading to accidental bites or scratches. The sampling method is also relatively rudimentary, and laboratory personnel are at risk of accidental injury and infection.

[0020] In this invention, the cooperation between the scraping component and the sealing plate solves the problems of traditional sampling and testing devices, which are mostly single-function designs, with sampling and scraping processes being independent of each other. They require additional tools to transfer samples, resulting in cumbersome and inefficient processes, tedious operation, insufficient accuracy, uneven sampling volume due to human error, or secondary contamination of the samples, affecting the accuracy of subsequent testing data.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

After efficient scraping sampling, the scraping component 5 is removed from the bottom of the shell 1, and the sample is squeezed out from the sampling tube 34 for use.

[0037] The adjustment assembly 2 includes two racks 214 fixedly connected to the inner walls of the outer shell 1 on opposite sides, a loading plate 21 disposed inside the upper section of the outer shell 1, and two support columns 22 fixedly connected to the upper side of the loading plate 21 near the two ends of the racks 214. An inner compartment 23 is provided on the opposite side of the two support columns 22. A gear 24 is rotatably connected to the middle of the inner compartment 23. A fixing column 25 is fixedly connected to the upper rear side of the right end of the loading plate 21. A rod 28 is fixedly connected to the upper front side of the right section of the loading plate 21. A gear 29 is rotatably connected to the rear top of the rod 28.

[0038] Gear 27 is fixedly connected to the front middle of gear 1 24 on the upper side of loading plate 21 near the fixed post 25. Pulley 210 is fixedly connected to the rear middle of gear 3 29. Pulley 211 is fixedly connected to the front middle of gear 1 24 on the upper side of loading plate 21 away from the fixed post 25.

[0039] A motor 26 is fixedly connected to the upper end of the fixed column 25. The output end of the motor 26 is fixedly connected to the middle rear side of the gear 24 near the end of the fixed column 25 on the upper side of the loading plate 21. The outer wall of the gear 27 meshes with the outer wall of the gear 3 29. The outer wall of the pulley 210 is connected to the outer wall of the pulley 211 through the synchronous belt 212.

[0040] The motor 26 and gear 27 are both located outside one of the support columns 22, and pulley 211 is located outside the other support column 22. The outer walls of the two gears 24 mesh with the adjacent sides of the two racks 214 respectively. This device can realize power transmission and sampling position adjustment, and bidirectional synchronous adjustment of the loading plate height. After the motor 26 starts, it drives the gear 24 on the same side to rotate. The gear 27 and gear 3 29 on the front side of the gear 24 mesh with each other, driving the pulley 210 to rotate. The pulley 210 is linked to the pulley 211 through the synchronous belt 212, so that the gear 24 on the other side rotates synchronously. The two gears 24 mesh with the racks 214 on the inner wall of the outer shell 1 respectively, driving the loading plate 21 to rise and fall smoothly along the four slides 8, and accurately adjusting the distance between the sampling component 3 and the scraping component 5.

[0041] The upper sides of the two support columns 22 are fixedly connected to the same buffer plate 213. The buffer plate 213 can prevent the loading plate 21 from colliding with the top of the outer shell 1 when it rises, thus improving the stability of adjustment. The upper inner wall of the outer shell 1 is fixedly connected to an anti-slip grip column 6. The operator holds the anti-slip grip column 6 and inserts the scraping component 5 into the mouth of the animal that needs to be sampled. The side of the container shell 51 with the scraping port 57 is attached to the cheek wall of the animal's mouth. The lower inner wall of the outer shell 1 is fixedly connected to an anti-detachment ring 4. The inner wall of the outer shell 1 is evenly provided with four sliding grooves 8. The four corners of the loading plate 21 are slidably connected to the inner walls of the four sliding grooves 8 respectively.

[0042] The sampling assembly 3 includes a telescopic rod 36 fixedly connected to the lower side of the middle part of the loading plate 21 and a motor 31 fixedly connected to the lower side of one end of the loading plate 21. The output end of the motor 31 is fixedly connected to a threaded rod 32, and the bottom end of the telescopic rod 36 is fixedly connected to a piston 37. A sampling cylinder 34 is sleeved on the outside of the piston 37.

[0043] Threaded sleeves 33 are fixedly connected to the outer walls of the upper and lower ends of the sampling cylinder 34 on the same side. The middle of the two threaded sleeves 33 is threaded to the outer wall of the threaded rod 32. A sampling tube 35 is fixedly connected to the middle of the lower end of the sampling cylinder 34. An anti-detachment block 38 is fixedly connected to the lower end of the threaded rod 32. The motor 31 starts and drives the threaded rod 32 to rotate. The sampling cylinder 34 moves up and down along the threaded rod 32 through the upper and lower threaded sleeves 33. With the extension guide of the telescopic rod 36, the extension length of the sampling tube 35 is adjusted to ensure that it accurately passes through the through hole 54 and enters the hollow column 53 for sampling. The telescopic rod 36 pushes the piston 37 to move downward in the sampling cylinder 34 and sucks in the sample through the sampling tube 35. The anti-detachment block 38 can prevent the sampling cylinder 34 from detaching from the threaded rod 32.

[0044] The scraping assembly 5 includes a container 51 that is snapped onto the lower side of the outer shell 1 and a motor 52 that is fixedly connected to the middle of the lower inner wall of the container 51. The output end of the motor 52 is fixedly connected to a hollow column 53. A slot 55 is opened through one side of the outer wall of the hollow column 53, and a through hole 54 is opened through the upper side of the hollow column 53.

[0045] A scraper 56 is fixedly connected to the middle of the inner wall of the slot 55. A scraping port 57 is opened through one side of the outer wall of the container 51. The end of the scraper 56 away from the hollow column 53 is set inside the scraping port 57. The motor 52 starts and drives the hollow column 53 to rotate back and forth, which drives the scraper 56 in the slot 55 to rotate synchronously. During the rotation of the scraper 56, the tissue sample on the cheek wall of the animal's mouth can be scraped. The sample flows along the scraper 56, through the slot 55 into the hollow column 53, which is convenient for subsequent detection and analysis.

[0046] A sealing plate 7 is fixedly connected to the inner wall of the container 51. The motor 52 is located on the lower side of the sealing plate 7. The hollow column 53 and the scraper 56 are both located on the upper side of the sealing plate 7. The scraping port 57 is located on the upper side of the sealing plate 7. The sealing plate 7 isolates the motor 52 from the sample to avoid contaminating the sample and ensure the accuracy of the test results.

[0047] Working principle: This device achieves precise adjustment, quantitative sampling, and efficient scraping of animal oral tissues and body fluids through the coordinated operation of adjustment components, sampling components, and scraping components. The core focuses on power transmission and multi-process adaptation. The operator holds the non-slip grip column 6 and inserts the scraping component 5 into the mouth of the animal requiring oral sampling. The side of the container 51 with the scraping port 57 is placed against the buccal wall of the animal's mouth. The motor 52 starts, driving the hollow column 53 to rotate reciprocally, which in turn drives the scraper 56 inside the slot 55 to rotate synchronously. During the rotation of the scraper 56, the scraper 56 scrapes the buccal wall of the animal's mouth. The tissue sample is scraped and flows along the scraper 56 through the slot 55 into the hollow column 53 for subsequent detection and analysis. After efficient scraping, the scraping component 5 is removed from the bottom of the outer shell 1, and the sample is squeezed out of the sampling cylinder 34 for use. This device can realize power transmission and sampling position adjustment. After the motor 26 starts, it drives the gear 24 on the same side to rotate. The gear 27 and gear 3 29 on the front side of the gear 24 mesh, driving the pulley 210 to rotate. The pulley 210 is linked to the pulley 211 through the synchronous belt 212, so that the other side of the pulley 211 rotates. Gear 24 rotates synchronously, and the two gears 24 mesh with the rack 214 on the inner wall of the outer casing 1, driving the loading plate 21 to rise and fall smoothly along the four sliding grooves 8, precisely adjusting the distance between the sampling component 3 and the scraping component 5. The buffer plate 213 can prevent the loading plate 21 from colliding with the top of the outer casing 1 when it rises, improving the stability of the adjustment. The motor 31 starts and drives the threaded rod 32 to rotate. The sampling tube 34 moves up and down along the threaded rod 32 through the upper and lower threaded sleeves 33. With the extension guide of the telescopic rod 36, the extension length of the sampling tube 35 is adjusted to ensure that it accurately passes through the through hole 54 and enters the hollow column 53. During sampling, the telescopic rod 36 pushes the piston 37 downward within the sampling cylinder 34, drawing in the sample through the sampling tube 35. The anti-detachment block 38 prevents the sampling cylinder 34 from detaching from the threaded rod 32. This device can perform sample scraping and collection in tandem. The sample transfer and cleaning components 5 and the outer shell 1 are designed with a snap-fit ​​connection, allowing for quick disassembly after sampling. This facilitates sample transfer and device cleaning. The sealing plate 7 isolates the motor 52 from the sample, preventing sample contamination and ensuring accurate test results. The anti-slip grip column 6 allows operators to hold the device easily, improving the stability of the sampling and scraping process and reducing the risk of operational errors.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
