Description

Technical Field

[0001] This invention belongs to the field of animal husbandry technology, specifically relating to an animal virus detection sample collection device. Background Technology

[0002] Bovine foot rot (also known as foot decay or infectious hoof dermatitis) is a common hoof disease in ruminants, primarily caused by bacterial infection, especially anaerobic bacteria such as *Fusobacterium necrophorum* and *Bacteroides putrefactivee*. This disease typically occurs in moist, muddy environments, leading to inflammation, ulceration, and tissue necrosis in the interhooves and soles, severely impacting the cattle's walking ability, reducing production performance, and increasing treatment costs. To effectively control bovine foot rot and other hoof diseases, regular hoof sampling and testing for viruses or pathogens is crucial. Regular monitoring allows for timely identification of infection signs, prevention of disease spread, and adjustments to feeding management and hygiene measures based on test results. This improves the overall health of the herd, prevents disease occurrence and development, and avoids production decline and additional medical expenses caused by disease.

[0003] Traditional animal virus testing sample collection methods involve manually using a hoof knife to directly collect tissue from the interhoof groove for testing. Since the deep interhoof groove near the junction of the two toes is one of the main sites of foot rot in cattle, the tissue in this area can directly reflect the viral infection status and help in developing targeted treatment plans. However, because the two toes of a cattle hoof are naturally tightly pressed together, especially deep in the interhoof groove near the junction, the space is very narrow, making it difficult for traditional tools to enter this area for sampling. Therefore, when collecting interhoof groove tissue, only tissue at the edge of the groove can be collected, failing to accurately collect tissue samples from the deep part of the interhoof groove near the junction of the two toes. This results in low sample quality and an inability to fully reflect the extent of infection. Summary of the Invention

[0004] To address the shortcomings and problems in existing bovine hoof virus detection sample collection methods, this invention provides an animal virus detection sample collection device. This device has a unique structure and ingenious design, ensuring high-quality sample acquisition through an expansion support and a ring-shaped blade hoof knife, simplifying the operation process and improving detection accuracy.

[0005] The solution adopted by this invention to solve its technical problem is as follows: an animal virus detection sample collection device, including a handle, a collection tube, a connecting frame, an expansion support, a lifting mechanism, and a sampling hoof knife. The tail end of the collection tube is vertically installed at the top front end of the handle. The sampling hoof knife is matched and installed inside the collection tube, and the driving end of the sampling hoof knife extends out of the collection tube. The driving end can drive the sampling hoof knife to extend out of the collection tube along the inner wall of the collection tube to cut and collect hoof samples. The connecting frame is located below the collection tube and connected to the collection tube. The expansion device includes a U-shaped shell, a power rod, and a side display frame. The U-shaped shell is fixedly installed on the bottom surface of the connecting frame below the front end of the collection tube, and the opening of the U-shaped shell faces downward. The side display frames are symmetrically hinged to the ends of the two side plates of the U-shaped shell, and the side display frames can slide along the ends of the side plates to control the extension length of the side display frames. The power rod is vertically slidably installed on the top plate of the U-shaped shell between the two side display frames. One end of the power rod is hinged to the two side display frames, and the other end extends upward into the connecting frame and is connected to the lifting mechanism. The lifting mechanism can control the sliding of the power rod.

[0006] The beneficial effects of this invention are as follows: The animal virus detection sample collection device provided by this invention significantly improves sampling accuracy and quality through its unique design, enabling precise collection of the most diagnostically valuable tissue samples from deep within the interhoof groove of cattle hooves. Simultaneously, the U-shaped shell and side-spreading frame design of the expansion support can safely open the two toes without harming the animal, exposing the interhoof groove, and simultaneously providing power for the collection tube to move deeper into the groove. The coordination of the power rod and lifting mechanism ensures operational safety and controllability. The device is easy to operate, allowing the sampling process to be completed with one hand, reducing labor intensity and increasing operational safety. The enclosed design effectively prevents accidental cuts, protecting the operator. Furthermore, the convenient sample processing mechanism ensures rapid sample acquisition and safe transfer, reducing the risk of contamination. The compact and stable structure, along with its ability to adapt to different interhoof groove sizes, enhances the device's durability and applicability. Ultimately, this device achieves a rapid and efficient sampling process, greatly improving work efficiency. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0015] To address the problems mentioned in the background section, this embodiment provides an animal virus detection sample collection device, such as... Figure 1-6 As shown, it includes a handle 2, a collection tube 3, a connecting frame 4, an expansion support 5, a lifting mechanism 6, and a sampling hoof knife. The tail end of the collection tube 3 is vertically installed on the top front end of the handle 2. The sampling hoof knife is installed inside the collection tube 3, and the driving end of the sampling hoof knife extends out of the collection tube. The driving end can drive the sampling hoof knife to extend out of the collection tube along the inner wall of the collection tube to cut and collect hoof samples.

[0016] like Figure 3As shown, the sampling hoof knife includes a blade tube 31, a piston block 32, and a push rod 33. The blade tube is slidably installed in the collection tube along the axial direction, and the front end of the blade tube is provided with an annular blade. When the blade tube slides out of the collection tube, the annular blade at the front end of the blade tube will cut the tissue in the interhoof groove 1 of the bovine hoof and collect it into the blade tube. A strip-shaped sliding hole 34 is provided along the axial direction on the collection tube on one side of the blade tube. A drive handle 35 is fixedly installed on the side wall of the blade tube facing the strip-shaped sliding hole. The drive handle 35 extends out of the collection tube through the strip-shaped hole and is driven by... The handle controls the extension and retraction of the blade tube; the piston block is fitted inside the collection tube and can slide along the axial direction of the collection tube. One end of the push rod is perpendicularly connected to the back of the piston block, and the other end extends backward through the blade tube to form a handle and is equipped with a push plate. During use, when the blade tube moves, it will drive the piston block and push rod to move synchronously. After the collection is completed, the blade tube position is fixed by driving the handle, and the push plate pushes the push rod into the blade tube to drive the piston block forward, which can directly push the sample tissue contained in the blade tube out of the blade tube, making it easy to pick up the sample.

[0017] There are several ways for the push rod to extend backward through the knife tube and out of the handle. For example, the rear end face of the handle is provided with a guide hole 36 that communicates with the collection tube, the rear end face of the knife tube is provided with an insertion hole that communicates with the inside of the knife tube, the push rod 33 is slidably installed in the guide hole, and the front end of the push rod passes through the insertion hole and is inserted into the knife tube and is perpendicularly connected to the rear end face of the piston block. The tail end of the push rod extends backward out of the guide hole and is fitted with a push plate.

[0018] The connecting frame 4 is positioned below the collection tube 3 and connected to it; the expansion support 5 includes a U-shaped outer shell 51, a power rod 52, and a side support 53. The U-shaped outer shell 51 is fixedly installed on the bottom surface of the connecting frame below the front end of the collection tube, thus connecting with the handle to form a whole. The opening of the U-shaped outer shell faces downwards. Specifically: Figure 2 As shown, the connecting frame 4 includes two guide frames symmetrically spaced apart. The guide frame includes a front connecting rod 41 and a rear connecting rod 42 arranged parallel to each other from front to back, and the length of the front connecting rod is less than the length of the rear connecting rod. A crossbar group is provided between the front connecting rod 41 and the rear connecting rod. The crossbar group is composed of multiple vertically parallel crossbars 43. The front and rear ends of each crossbar in the crossbar group are perpendicularly connected to the front connecting rod and the rear connecting rod, respectively. The front section of the bottom crossbar in the crossbar group is fixedly connected to the top plate of the U-shaped shell. The bottom end of the rear connecting rod is vertically connected to a fixed section 44. The fixed section is set to the rear and fixedly connected to the handle, thereby further enhancing the connection strength between the connecting frame and the handle.

[0019] Side display frames 53 are symmetrically hinged to the ends of the two side plates of the U-shaped shell 51. The side display frames 53 can slide along the ends of the side plates to control the extension length of the side display frames. The power rod 52 is vertically slidably installed on the top plate of the U-shaped shell between the two side display frames 53. The bottom end of the power rod is hinged to the two side display frames, and the top end of the power rod extends upward into the connecting frame and is connected to the lifting mechanism. The sliding of the power rod can be controlled by the lifting mechanism.

[0020] like Figure 3 and Figure 4 As shown, the top of the power rod 52 extends upward to the space between the two guide frames of the connecting frame and is connected to the lifting mechanism. The lifting mechanism can drive the power rod to rise and fall to its limit height and fix its height when it falls to the limit height. The lifting mechanism includes a drive rod 61, a grooved roller 62, a lifting handle 63, and an elastic support member 64. The drive rod 61 is matched and installed in the connecting frame above the power rod and can slide up and down along the connecting frame. Specifically, the drive rod is matched and installed between the two guide frames of the connecting frame and can slide up and down along the two guide frames. There are several ways to install the drive rod between the two guide frames. For example, both the front and rear ends of the drive rod 61 extend outward from the connecting frame and are fixed with limit sliders 65. The limit sliders 65 slide against the outer wall of the connecting rod on the same side of the two guide frames, and the distance between the two guide frames matches the diameter of the drive rod. Thus, under the constraint of the limit sliders at the front and rear ends of the drive rod and the two guide frames, the drive rod can only slide up and down between the two guide frames.

[0021] The drive rod 61 includes an upper horizontal section 611, a lower horizontal section 612, and an inclined section 613. The upper horizontal section is positioned above the drive rod and vertically connected to the top of the drive rod. The tail end of the upper horizontal section extends rearward into a U-shaped housing and connects to the lower horizontal section via the inclined section. A grooved roller 62 is matched and positioned between two guide frames above the lower horizontal section, and is slidably mounted on a connecting frame via a lifting handle. An elastic support frame is mounted on the connecting frame, and in its natural state, the elastic support pushes the drive rod upward to move horizontally and contact the grooved roller. Specifically: Figure 3 As shown, the elastic support 64 is located between the rear limiting slider and the fixed section. In its natural state, the elastic support pushes the drive rod upward to move horizontally and contact the grooved roller. Thus, when the grooved roller is driven to move forward along the drive rod by the lifting handle, the grooved roller can only move horizontally along the connecting frame under the constraint of the lifting handle. Therefore, when the grooved roller moves horizontally upward along the inclined section of the drive rod, it pushes the drive rod downward to move horizontally, causing the power rod to slide downward. Conversely, when the grooved roller moves horizontally downward along the inclined section of the drive rod, the elastic support pushes the rear limiting slider upward to move the drive rod upward, thereby controlling the power rod to slide upward.

[0022] like Figure 5As shown, two connecting blocks are spaced apart at the ends of the two side plates of the U-shaped shell. The connecting blocks are hinged to the ends of the two side plates of the U-shaped shell on the same side via hinge shafts 55. The end of the connecting block away from the hinge shaft has a vertical sliding hole 541. The angle between the central axis of the sliding hole 541 and the hinge shaft 55 of the connecting block is 90 degrees. The side display frame 53 includes a U-shaped rod 531 and a pushing crossbar 532. The two parallel sections of the U-shaped rod are respectively inserted into the sliding holes of the two connecting blocks on the same side plate and can slide along the axial direction of the sliding holes. The vertical section of the U-shaped rod is located on the outside of the U-shaped shell. The ends of the two parallel sections of the U-shaped rod away from the vertical section of the U-shaped rod are fixedly connected together by the pushing crossbar. The top of the power rod is directly connected to the pushing crossbar of the left and right side display frames. The horizontal bars are hinged together, so when the power rod slides vertically, it simultaneously drives the two display frames to slide synchronously along the corresponding connecting blocks. During the sliding process, the two display frames drive the connecting blocks to rotate around the ends of the two side plates of the U-shaped shell. In use, when the power rod moves down and pushes the two display frames outward through the connecting blocks to extend downward into the U-shaped shell, the two display frames will rotate outward in opposite directions around the ends of the two side plates of the U-shaped shell through the connecting blocks, protruding out of the U-shaped shell. Conversely, when the power rod moves up and pulls the two display frames back into the U-shaped shell through the connecting blocks, the two display frames will rotate in opposite directions around the ends of the two side plates of the U-shaped shell through the connecting blocks, reducing the distance between the far ends of the two display frames.

[0023] In this embodiment, the animal virus detection sample collection device is used by holding the handle and inserting the front end of the collection tube and the expansion support into the interhoof groove 1 of the cow's hoof, at the junction of the two toes at the top. The collection tube is positioned at the top, and the expansion support is positioned at the bottom. After insertion, the lifting mechanism drives the two side frames of the expansion support to rotate outward in opposite directions through the connecting blocks around the ends of the two side plates of the U-shaped shell, protruding out of the U-shaped shell and contacting the inner walls of the left and right toes of the cow's hoof, thus separating the two toes and exposing the interhoof groove. This process... Driven by the power rod, the side display stand continuously extends its U-shaped outer shell. As the two far ends of the side display stand are supported against the inner walls of the left and right toes respectively, the collection tube is synchronously pushed towards the intersection of the two toes deep in the interhoof groove as the two toes are spread apart. After the power rod descends to its limit position and fully spreads the two toes, the driving end can drive the sampling hoof knife to extend outward along the inner wall of the collection tube to directly collect tissue samples from the deep interhoof groove of the bovine hoof. This ensures the quality of the samples and facilitates the detection of whether the bovine hoof is infected with or carries foot rot virus. Example

[0024] The difference between Embodiment 2 and Embodiment 1 is that the lifting handle 63 includes a fixed square sleeve 631 that is fitted onto the two crossbar groups of the connecting frame. The bottom of the fixed square sleeve is provided with a handle 632. The fixed square sleeve can slide back and forth along the two crossbar groups. The grooved roller is located inside the fixed square sleeve, and the drive rod passes through the fixed square sleeve.

[0025] Furthermore, the fixed square sleeve below the drive rod is provided with a vertical clearance groove 633 for avoiding the inclined section when passing through it. Example

[0026] The difference between Example 3 and Example 2 is that the top of the U-shaped outer shell is provided with an inverted V-shaped shell, and the ends of the collection tube and the connecting frame are located inside the inverted V-shaped shell, so that the front end of the collection device can be easily inserted into the groove between the hooves of cattle during use.

Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.
