Description

Technical Field

[0001] This utility model belongs to the technical field of veterinary fecal samplers, specifically relating to a portable veterinary fecal sampler. Background Technology

[0002] Veterinarians are doctors who prevent, diagnose, and treat diseases in animals. They are professionals who use medical methods to promote harmony between the animal body, microorganisms, and the natural environment. Veterinarians treat wild animals, poultry, livestock, and aquatic animals. Animal feces can usually accurately reflect the health status of an animal and play an important role in the diagnosis, treatment, and protection of animals. The collection of fecal samples is an important step in determining the health status of animals and detecting pathogens.

[0003] Existing sampling tools are mostly scattered test tubes, tweezers, spoons, etc., lacking a standardized storage structure. They are easily lost or damaged by collisions during transport. After sampling, the sample container is exposed to the outside, making it susceptible to external contamination. It may also leak feces due to shaking, contaminating the transport environment. Furthermore, animal feces vary greatly in state, such as hard feces from healthy animals and soft feces from animals with diarrhea. Universal sampling tools are difficult to adapt to feces in different states, which can easily lead to incomplete sample collection and affect the accuracy of testing. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a portable veterinary fecal sampler, which solves the problems of existing veterinary fecal sampling tools lacking a standardized storage structure, making them easy to lose or damage when carried, and samples easily exposed and contaminated, and leaking out. At the same time, general-purpose tools are difficult to adapt to feces in different states such as hard and soft stools, which can easily lead to incomplete sample collection and affect the accuracy of testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable veterinary fecal sampler, comprising a storage box for holding the sampler, a storage plate fixed inside the storage box, a protective cylinder inserted into the storage plate, a protective cover covering the top of the storage box, a plurality of abutments fixed at intervals on the inner top surface of the protective cover, a splicing seat threadedly connected to the top of the inner part of the protective cylinder, and the ends of the abutments abutting against the top surface of the splicing seat to fix the splicing seat, a lead screw threadedly connected through the center of the splicing seat, the bottom end of the lead screw extending into the protective cylinder and connected to a sampling component, the sampling component including a... A soft stool sampling component for soft stool sampling and a hard stool sampling component for hard stool sampling are provided, with the soft stool sampling component and the hard stool sampling component respectively disposed below different splicing bases. The soft stool sampling component includes a sampling cylinder fixed to the bottom surface of the splicing base, and a piston plate slidably fitted inside the sampling cylinder. The piston plate is connected to the bottom end of a lead screw. The hard stool sampling component includes a mounting shell fixed to the bottom surface of the splicing base, and a rack slidably disposed inside the mounting shell. The rack meshes with gears rotatably disposed on both sides of the mounting shell. One end of the gear is connected to a fixing rod, and the other end of the fixing rod is provided with a stool clamping spoon.

[0006] The beneficial effects of this utility model are: The protective sleeve on the placement plate can independently hold each sampling component, preventing the components from being scattered and lost. The abutment on the top surface of the inner protective cover abuts against the top surface of the splicing base, which can fix all components during transportation and prevent damage caused by shaking and collision.

[0007] The soft stool sampling component uses the sliding engagement of the sampling cylinder and the piston plate to draw in soft stool through the suction hole using negative pressure, avoiding adhesion and leakage. The hard stool sampling component uses a rack and pinion meshing with a gear to drive the hemispherical stool clamp to close into a spherical shape, which can firmly wrap the hard stool and prevent it from breaking or falling off. This allows the device to take samples of stool in different states, ensuring sample integrity and improving sampling efficiency.

[0008] To visually distinguish between soft stool sampling components and hard stool sampling components: As a further improvement to the above technical solution: the splicing base is provided in several groups, and some of the splicing bases have annular marking grooves on their top surfaces. The soft stool sampling component is correspondingly set on the bottom surface of the splicing base with the annular marking groove, and the hard stool sampling component is set on the bottom surface of the remaining splicing bases.

[0009] The beneficial effects of this improvement are: the annular marking groove on the top surface of the splicing base enables a direct distinction between the soft stool sampling component and the hard stool sampling component, allowing users to select the appropriate component based on the state of the animal's feces.

[0010] To collect soft stool by suctioning: As a further improvement to the above technical solution: one end of the lead screw that passes through the bottom surface of the splicing seat is rotatably connected to the top surface of the piston plate, the piston plate is in contact with and slides against the inner wall of the sampling cylinder, and the bottom end of the sampling cylinder is provided with a suction hole for soft materials to enter.

[0011] The beneficial effects of this improvement are as follows: by rotating the lead screw, the piston plate slides inside the sampling cylinder. When it slides upward, a negative pressure is formed inside the sampling cylinder, and soft stool can be sucked into the sampling cylinder through the suction hole at the bottom, thus achieving rapid collection.

[0012] In order to drive the rack to precisely mesh with the gears on both sides: As a further improvement to the above technical solution: a through hole is provided through the center of the mounting shell, a limiting seat is fixed at the bottom end of the through hole, a guide rod is fixed at the center of the inner bottom surface of the limiting seat, the rack is fixed on both sides of the connecting plate, the connecting plate and the guide rod are slidably engaged, and one end of the lead screw that passes through the bottom surface of the splicing seat is rotatably connected to the top surface of the connecting plate.

[0013] The beneficial effects of this improvement are: when gripping hard stool, the limiting seat and guide rod inside the mounting shell form a sliding guide for the connecting plate, so that the rack can only move in a fixed direction, driving the rack to accurately mesh with the gears on both sides.

[0014] In order to completely enclose the hard stool within the spherical space: As a further improvement to the above technical solution: the inner walls of the through hole on both sides of the mounting shell are rotatably provided with mounting seats, the gear is fixed on the inner side of the mounting seat, the bottom end of the mounting seat is connected to the fixing rod, the clamping spoon is fixed on the bottom end of the fixing rod and is hemispherical, and the clamping spoons on the two sets of fixing rods can be closed to form a sphere.

[0015] The beneficial effects of this improvement are as follows: the gear drives the fixed rod and the clamping spoon to rotate through the mounting base, realizing the opening and closing action. The two sets of clamping spoons can close into a spherical shape, which can completely wrap the hard stool in the spherical space, preventing the hard stool from falling or breaking during the sampling process and ensuring the integrity of the sample.

[0016] For easy and quick loading and unloading: As a further improvement to the above technical solution: the protective cylinder includes a connecting ring fixed at the top, and the inner wall of the connecting ring is provided with an internal thread that is adapted to connect with the external thread on the outer side of the bottom end of the splicing seat.

[0017] The beneficial effects of this improvement are as follows: the connecting ring at the top of the protective cylinder is connected to the external thread at the bottom of the splicing seat through the internal thread, which not only ensures the stability of the connection between the two, but also facilitates quick loading and unloading by veterinarians. When it is necessary to replace the sampling component, it can be separated or installed simply by rotating the splicing seat, which is easy to operate.

[0018] In summary, the beneficial effects of this case are as follows: The protective sleeve on the placement plate can independently hold each sampling component, preventing the components from being scattered and lost. The abutment on the top surface of the inner protective cover abuts against the top surface of the splicing base, which can fix all components during transportation and prevent damage caused by shaking and collision.

[0019] The soft stool sampling component uses the sliding engagement of the sampling cylinder and the piston plate to draw in soft stool through the suction hole using negative pressure, avoiding adhesion and leakage. The hard stool sampling component uses a rack and pinion meshing with a gear to drive the hemispherical stool clamp to close into a spherical shape, which can firmly wrap the hard stool and prevent it from breaking or falling off. This allows the device to take samples of stool in different states, ensuring sample integrity and improving sampling efficiency.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0023] like Figure 1-5As shown, a portable veterinary fecal sampler includes a storage box 1 for storage, a storage plate 101 fixed inside the storage box 1, a protective cylinder 3 inserted into the storage plate 101, a protective cover 2 covering the top surface of the storage box 1, and a plurality of abutment plates 201 fixed at intervals on the inner top surface of the protective cover 2. A splicing seat 6 is threadedly connected to the top end of the inner part of the protective cylinder 3, and the ends of the abutment plates 201 abut against the top surface of the splicing seat 6 to fix the splicing seat 6. A lead screw 7 is threaded through and connected to the center of the splicing seat 6, and the bottom end of the lead screw 7 extends into the protective cylinder 3 and is connected to a sampling component. The sampling component includes a soft stool sampling component 4 for soft stool sampling and a hard stool sampling component 4 for hard stool sampling. The soft stool sampling component 4 and the hard stool sampling component 5 are respectively disposed below different splicing bases 6. The soft stool sampling component 4 includes a sampling cylinder 402 fixed to the bottom surface of the splicing base 6. A piston plate 401 is slidably fitted inside the sampling cylinder 402. The piston plate 401 is connected to the bottom end of the lead screw 7. The hard stool sampling component 5 includes a mounting shell 501 fixed to the bottom surface of the splicing base 6. A rack 505 is slidably disposed inside the mounting shell 501. The rack 505 meshes with gears 502 rotatably disposed on both sides of the mounting shell 501. One end of the gears 502 is connected to a fixing rod 503. The other end of the fixing rod 503 is provided with a stool clamping spoon 504.

[0024] The splicing base 6 is provided in several groups. Some of the splicing bases 6 have annular marking grooves on their top surfaces. The soft stool sampling component 4 is correspondingly set on the bottom surface of the splicing base 6 with the annular marking groove, while the bottom surface of the remaining splicing bases 6 is provided with hard stool sampling components 5. The annular marking grooves on the top surface of the splicing base 6 enable intuitive differentiation between the soft stool sampling component 4 and the hard stool sampling component 5, allowing users to select according to the state of the animal's feces.

[0025] One end of the lead screw 7, which passes through the bottom surface of the splicing base 6, is rotatably connected to the top surface of the piston plate 401. The piston plate 401 is in contact with and slides against the inner wall of the sampling cylinder 402. The bottom end of the sampling cylinder 402 is provided with a suction hole for the soft stool to enter. By rotating the lead screw 7, the piston plate 401 is driven to slide inside the sampling cylinder 402. When it slides upward, a negative pressure is formed inside the sampling cylinder 402, and the soft stool can be sucked into the sampling cylinder 402 through the suction hole at the bottom end, thus achieving rapid collection.

[0026] The mounting shell 501 has a through hole in its center, and a limiting seat 5011 is fixed at the bottom end of the through hole. A guide rod is fixed at the center of the inner bottom surface of the limiting seat 5011. The rack 505 is fixed on both sides of the connecting plate. The connecting plate and the guide rod are slidably engaged. One end of the lead screw 7, which passes through the bottom surface of the splicing base 6, is rotatably connected to the top surface of the connecting plate. When grabbing a hard object, the limiting seat 5011 and the guide rod inside the mounting shell 501 form a sliding guide for the connecting plate, so that the rack 505 can only move in a fixed direction, driving the rack 505 to precisely mesh with the gears 502 on both sides.

[0027] Mounting seats are rotatably mounted on the inner walls of both sides of the through hole of the mounting shell 501. The gear 502 is fixed to the inner side of the mounting seat. The bottom end of the mounting seat is connected to the fixing rod 503. The clamping spoon 504 is fixed to the bottom end of the fixing rod 503 and is hemispherical. The clamping spoons 504 on the two sets of fixing rods 503 can close to form a sphere. The gear 502 drives the fixing rod 503 and the clamping spoon 504 to rotate through the mounting seat, realizing the opening and closing action. The two sets of clamping spoons 504 can close to form a sphere, which can completely wrap the hard stool in the spherical space, avoid the hard stool from falling or breaking during the sampling process, and ensure the integrity of the sample.

[0028] The protective cylinder 3 includes a connecting ring 301 fixed at the top, and the inner wall of the connecting ring 301 is provided with an internal thread that is adapted to the external thread on the outer side of the bottom of the splicing seat 6. The connecting ring 301 at the top of the protective cylinder 3 is adapted to the external thread at the bottom of the splicing seat 6 through the internal thread, which not only ensures the stability of the connection between the two, but also facilitates quick loading and unloading by veterinarians. When it is necessary to replace the sampling component, it can be separated or installed simply by rotating the splicing seat 6, which is simple to operate.

[0029] The working principle and usage process of this utility model: The veterinarian carries the closed placement box 1 to the sampling site. Upon arrival, the veterinarian opens the protective cover 2 on the top surface of the placement box 1. At this time, the abutment plate 201 on the top surface of the inner protective cover 2 separates from the top surface of the splicing base 6, releasing the restriction on the splicing base 6. Several protective cylinders 3 are inserted into the placement plate 101 inside the placement box 1. Each protective cylinder 3 is fixed to the splicing base 6 by a threaded connection. The soft stool sampling component 4 or hard stool sampling component 5 is connected to the bottom of the splicing base 6. The veterinarian can quickly distinguish between the two by observing whether there is an annular marking groove on the top surface of the splicing base 6. Below the splicing base 6 is the soft stool sampling component 4, and the rest are hard stool sampling components 5. The veterinarian can then observe the animal's feces to select the appropriate component. If the feces are soft and fluid, select the protective cylinder 3 corresponding to the splicing base 6 with the annular marking groove. If the feces are solid and lumpy, select the protective cylinder 3 corresponding to the splicing base 6 without the annular marking groove. After selection, hold the splicing base 6 and rotate it to separate the external thread on the outer side of its bottom end from the internal thread on the inner wall of the connecting ring 301 at the top of the protective cylinder 3. The splicing base 6 and the sampling components connected below it can then be removed from the protective cylinder 3. (For soft stool sampling...) Align the bottom end of the sampling cylinder 402 of the soft stool sampling assembly 4 with the soft stool, and rotate the lead screw 7. Because the lead screw 7 is threadedly connected to the center of the splicing seat 6, the lead screw 7 will move upward when rotated. The piston plate 401, which is rotatably connected to its bottom end, will also move upward. The piston plate 401 will fit against and slide against the inner wall of the sampling cylinder 402. At this time, a negative pressure will be formed inside the sampling cylinder 402. The soft stool will be sucked into the sampling cylinder 402 through the suction hole at the bottom end of the sampling cylinder 402. After sampling is completed, rotate the lead screw 7 in the opposite direction. The piston plate 401 will move down to close the suction hole and prevent the soft stool from leaking out. When sampling hard stool, rotate the lead screw 7. The bottom end of the lead screw 7 will rotate. The connecting plate slides downward under the guidance of the guide rod in the limiting seat 5011. The rack 505 then meshes with the gears 502 on both sides of the mounting shell 501. The gears 502 drive the fixing rod 503 to rotate outward through the mounting seat. The two sets of hemispherical scoops 504 open and hold the hard stool. The screw 7 is rotated in the opposite direction, the connecting plate drives the rack 505 to move upward, the gears 502 rotate in the opposite direction, and the fixing rod 503 retracts inward. The two sets of scoops 504 close into a spherical shape, completely wrapping the hard stool inside. After sampling, the sampling component is put back into the corresponding protective cylinder 3 to complete the sampling.
