Description

Technical Field

[0001] This invention relates to the field of sampling device technology, specifically to an animal oral fluid sampling device for animal diseases. Background Technology

[0002] An animal oral fluid sampling device is a medical instrument or tool specifically designed for collecting oral fluid from animals. It is primarily used for the detection, diagnosis, and research of animal diseases. By collecting oral fluid samples, it is possible to detect whether an animal is infected with viruses, bacteria, or other pathogens, such as rabies, foot-and-mouth disease, and swine fever.

[0003] Patent publication number CN221205489U relates to the field of sampling device technology. This patent provides an animal oral fluid sampling device, comprising: a main body block; and a handle welded to the main body block for gripping. During sampling, the improved design allows the animal's mouth to be opened, preventing bites to personnel and improving overall safety. After opening the animal's mouth, the fluid inside can be easily collected, completing the initial sampling. Subsequent sampling can then be performed directly from the collection box, making sampling convenient and quick. This solves the problem of potential bites when sampling from an animal's mouth using traditional methods. Currently, sampling requires opening the animal's mouth and then using a sampler, requiring one hand to sample and the other to control the sampler while opening the animal's mouth, leading to decreased stability and the risk of accidents if the sampler detaches from the animal's mouth.

[0004] In the aforementioned patent, the animal's mouth is opened by an improvement, which can prevent the animal from biting the staff and improve the overall safety performance. However, when sampling the liquid in the animal's mouth, it is difficult to fix the animal and keep it still, which can easily lead to the animal moving around and endangering the staff during sampling. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an animal oral fluid sampling device for animal diseases, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an animal oral fluid sampling device for animal diseases, comprising a body, a motor fixedly installed on the top of the body, a reciprocating lead screw fixedly installed on the output end of the motor, two spiral grooves opened on the circumferential surface of the reciprocating lead screw, a sleeve slidably installed on the inner wall of each of the two spiral grooves, and a fixing device provided on the top of the body;

[0007] The fixing device includes a fixing rod, a rubber block, rotating columns, a transmission belt, a connecting rod, a top rod, and a top cover. The fixing rod is fixedly installed on the circumferential surface of the sleeve. The rubber block is fixedly installed on the top of the fixing rod. The two rotating columns are rotatably installed on the inner wall of the machine body and are connected by the transmission belt. One end of the connecting rod is fixedly installed on the back of the transmission belt, and the other end of the connecting rod is fixedly installed on the circumferential surface of the sleeve. The top rod is fixedly installed on the side of the transmission belt away from the sleeve. The top cover is fixedly installed on the top of the top rod. When the sleeve moves, the connecting rod moves upward. The movement of the connecting rod causes the transmission belt to rotate around the two rotating columns. The rotation of the transmission belt causes the top rod to move downward. The movement of the top rod causes the top cover to move downward.

[0008] The device is equipped with stabilizing devices for stabilizing the animal and protective devices for preventing contamination of oral fluids on its left and right sides. The stabilizing devices ensure the smooth progress of the sampling process, while the protective devices prevent sudden movements from startling the animal and reduce its stress response.

[0009] According to the above technical solution, the two spiral grooves are in opposite directions, and the push rod slides through the machine body. By setting spiral grooves in opposite directions, it is ensured that the two sleeves can move in different directions, and by sliding through, it is ensured that the push rod can move smoothly.

[0010] According to the above technical solution, the stabilizing device includes a rotating rod, a first gear, a threaded rod, a second gear, a second sleeve, a base rod, a sliding column, and a clamping rod. The rotating rod is rotatably mounted on the top of the inner wall of the machine body. The first gear is fixedly mounted on the bottom of the rotating rod. The threaded rod is rotatably mounted on the inner wall of the machine body. The second gear is fixedly mounted on the end of the threaded rod away from the inner wall of the machine body. The second sleeve is threadedly connected to the threaded rod. The base rod is fixedly mounted on the circumferential surface of the second sleeve. The sliding column is fixedly mounted on the side of the base rod near the inner wall of the machine body. The clamping rod is fixedly mounted on the end of the sliding column away from the base rod. Simultaneously, the rotating rod is driven to rotate via a second transmission belt. The rotation of the rotating rod drives the first gear to rotate. The rotation of the first gear drives the second gear to rotate. The rotation of the second gear drives the threaded rod to rotate. The rotation of the threaded rod drives the second sleeve to move towards the second gear. The movement of the second sleeve drives the sliding column to move. The movement of the sliding column drives the clamping rod to move.

[0011] According to the above technical solution, the stabilizing device further includes a push rod, an elastic telescopic rod, a collection tray, and a first inclined block. The push rod is fixedly installed at the bottom of the clamping rod, the elastic telescopic rod is fixedly installed at the bottom of the machine body, the collection tray is fixedly installed at the movable end of the elastic telescopic rod, and the first inclined block is fixedly installed on the back of the collection tray. When the clamping rod moves, it drives the push rod to start moving. The push rod moves and contacts and pushes the first inclined block to start moving. The movement of the first inclined block drives the collection tray to start moving forward. After the animal is fixed, the collection tray can be pushed out to accurately collect oral fluid.

[0012] According to the above technical solution, the rotating rod and the reciprocating lead screw are connected by a transmission belt, the first gear meshes with the second gear, the sliding column slides through the machine body, and the sides of the push rod and the inclined block are both set as inclined surfaces. The transmission connection ensures that the reciprocating lead screw can drive the rotating rod to rotate when it rotates, the meshing ensures that the first gear can drive the second gear to rotate when it rotates, and the inclined surface ensures that the push rod can smoothly push the inclined block when it moves.

[0013] According to the above technical solution, the protective device includes a slide rail, a second inclined block, a limiting plate, a baffle, and a fixing block. The slide rail is fixedly installed at the bottom of the machine body, the second inclined block is fixedly installed at the bottom of the slide rail, the limiting plate is fixedly installed on the left side of the collection drawer, the baffle is slidably installed at the top of the collection drawer, and the fixing block is fixedly installed at the top of the baffle. When the collection drawer moves, it drives the baffle to move. The movement of the baffle drives the fixing block to move. The movement of the fixing block contacts the second inclined block and pushes the baffle towards the limiting plate. The movement of the baffle opens the collection drawer. The process of gradually pushing out and opening the collection drawer is more stable.

[0014] According to the above technical solution, the protective device also includes a collection box, a handle, a button, a ramp, and a limiting block. The collection box is slidably installed inside the collection drawer. The handle is fixedly installed at the front of the collection box. The button slides through the handle. The ramp is slidably installed at the front of the collection box. The limiting block is fixedly installed at the front of the collection drawer. By pressing the button and pushing the ramp to start moving downward, the ramp moves and disengages from the limiting block. Then, the operator manually pulls the handle to pull the collection box out from inside the collection drawer.

[0015] According to the above technical solution, the slide rail contacts the collection drawer, the side of the inclined block two that contacts the fixed block is set as an inclined surface, the side of the button that contacts the inclined rod is set as an inclined surface, a spring one is provided between the button and the collection box, and a spring two is provided between the inclined rod and the collection box. The contact ensures that the collection drawer can move along the designated track, the inclined surface ensures that the fixed block can be pushed smoothly when it contacts the inclined block two, the inclined surface ensures that the button can push the inclined rod smoothly when it moves, the spring one ensures that the button can achieve self-reset, and the spring two ensures that the inclined rod can achieve self-reset.

[0016] This invention provides a device for sampling oral fluid from animals for animal diseases. It has the following beneficial effects:

[0017] (1) The invention uses two rubber blocks to move and hold the animal's upper and lower jaws respectively, keeping the oral cavity open and facilitating the entry of the sampling device, thus improving operational efficiency. At the same time, the soft rubber material can reduce damage to the animal's oral cavity and avoid discomfort or injury during sampling. The movement of the protective top can block part of the field of vision when sampling oral fluid, reducing the animal's perception of the external environment, alleviating its tension, thereby reducing stress response and making the animal more cooperative with sampling. At the same time, the use of the protective top can reduce the need for additional animal fixation, simplify the operation steps, and save time and manpower.

[0018] (2) The invention can effectively control the movement of the animal's head by moving the clamping rod, preventing it from struggling or swinging, and ensuring that the sampling process is carried out smoothly. At the same time, after the head is fixed, the operator can use the sampling device more accurately, reduce the operation time, and improve efficiency. After the animal is fixed, the collection tray can be pushed out to accurately collect oral fluid, avoiding sample contamination or omission caused by the animal's movement, and improving the accuracy of the test. At the same time, after the animal is fixed, the operator can focus more on sampling without having to be distracted by controlling the animal, thereby improving efficiency.

[0019] (3) The invention makes the process of gradually pushing out and opening the collection drawer smoother, avoids sudden movements that frighten animals and reduces their stress response. At the same time, the operation of pushing out and opening the collection drawer is more orderly, reducing the possibility of operational errors and repeated sampling, and improving overall efficiency.

[0020] (4) The invention restricts the collection box by contacting the inclined rod with the limiting block to ensure that the next sampling device remains stable during operation, avoiding sampling errors caused by shaking or displacement. At the same time, preventing excessive movement of the collection box can reduce the risk of accidental collisions or equipment damage during operation, and protect the safety of operators and animals.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Please see Figures 1-8 One embodiment of the present invention is: an animal oral fluid sampling device for animal diseases, including a body 1, a motor 2 fixedly installed on the top of the body 1, a reciprocating screw 3 fixedly installed on the output end of the motor 2, two spiral grooves are opened on the circumferential surface of the reciprocating screw 3, and a sleeve 4 is slidably installed on the inner wall of the two spiral grooves, and a fixing device is provided on the top of the body 1.

[0032] The fixing device includes a fixing rod 5, a rubber block 6, a rotating column 7, a transmission belt 8, a connecting rod 9, a top rod 10, and a top cover 11. The fixing rod 5 is fixedly installed on the circumferential surface of the sleeve 4, the rubber block 6 is fixedly installed on the top of the fixing rod 5, the two rotating columns 7 are rotatably installed on the inner wall of the body 1, and the two rotating columns 7 are connected by the transmission belt 8. One end of the connecting rod 9 is fixedly installed on the back of the transmission belt 8, and the other end of the connecting rod 9 is fixedly installed on the circumferential surface of the sleeve 4. The top rod 10 is fixedly installed on the side of the transmission belt 8 away from the sleeve 4, and the top cover 11 is fixedly installed on the top of the top rod 10. The movement of the clamping rod 128 can effectively control the movement of the animal's head, prevent it from struggling or swinging, and ensure that the sampling process is carried out smoothly. At the same time, after the head is fixed, the operator can use the sampling device more accurately, reduce the operation time, and improve efficiency.

[0033] The two spiral grooves are in opposite directions, and the push rod 10 slides through the body 1. By setting opposite spiral grooves, it is ensured that the two sleeves 4 can move in different directions, and by sliding through, it is ensured that the push rod 10 can move smoothly.

[0034] In this embodiment, the operation is as follows: First, the staff checks whether the equipment is working properly. After confirming that everything is in order, the staff picks up the animal for which oral fluid sampling is required. Then, the staff opens the animal's mouth so that it bites the rubber block 6 on the fixing rod 5. After confirming that the animal has bitten the rubber block 6, the staff starts the motor 2, which drives the reciprocating screw 3 to rotate. The rotation of the reciprocating screw 3 causes the two sleeves 4 to move upward and downward respectively. The movement of the two sleeves 4 causes the two fixing rods 5 to move upward and downward respectively. The movement of the two fixing rods 5 causes the two rubber blocks 6 to move. The two rubber blocks 6 move and respectively press against the animal's upper and lower jaws, fixing the upper and lower jaws to keep the oral cavity open, facilitating... The sampling device enters, improving operational efficiency. The soft rubber material reduces harm to the animal's mouth, preventing discomfort or injury during sampling. As the sleeve 4 moves, the connecting rod 9 moves upwards. The moving connecting rod 9 causes the transmission belt 8 to rotate around the two rotating columns 7. The rotating transmission belt 8 causes the top rod 10 to move downwards. The moving top rod 10 then causes the protective cover 11 to move downwards. When sampling oral fluids, the protective cover 11 partially obstructs the animal's vision, reducing its perception of the external environment and alleviating its anxiety, thus reducing stress and making the animal more cooperative during sampling. Furthermore, the use of the protective cover 11 reduces the need for additional animal restraint, simplifying the operation and saving time and manpower.

[0035] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the left and right sides of the body 1 are provided with stabilizing devices for stabilizing the animal and protective devices for preventing oral fluid from being contaminated. The stabilizing devices ensure that the sampling process is carried out smoothly, and the protective devices prevent sudden movements from startling the animal and reduce its stress response.

[0036] The stabilizing device includes a rotating rod 121, a first gear 122, a threaded rod 123, a second gear 124, a second sleeve 125, a base rod 126, a sliding column 127, and a clamping rod 128. The rotating rod 121 is rotatably mounted on the top of the inner wall of the machine body 1. The first gear 122 is fixedly mounted on the bottom of the rotating rod 121. The threaded rod 123 is rotatably mounted on the inner wall of the machine body 1. The second gear 124 is fixedly mounted on the end of the threaded rod 123 away from the inner wall of the machine body 1. The second sleeve 125 is threadedly connected to the threaded rod 123. The base rod 126 is fixedly mounted on the circumferential surface of the second sleeve 125. The sliding column 127 is fixedly mounted on the side of the base rod 126 near the inner wall of the machine body 1. The clamping rod 128 is fixedly mounted on the end of the sliding column 127 away from the base rod 126. By moving the clamping rod 128, the movement of the animal's head can be effectively controlled to prevent it from struggling or swaying, ensuring a smooth sampling process. At the same time, after the head is fixed, the operator can use the sampling device more accurately, reducing operation time and improving efficiency.

[0037] The stabilizing device also includes a push rod 129, an elastic telescopic rod 1210, a collection tray 1211, and a ramp block 1212. The push rod 129 is fixedly installed at the bottom of the clamping rod 128, the elastic telescopic rod 1210 is fixedly installed at the bottom of the machine body 1, the collection tray 1211 is fixedly installed at the movable end of the elastic telescopic rod 1210, and the ramp block 1212 is fixedly installed on the back of the collection tray 1211. After the animal is fixed, the collection tray 1211 can be pushed out to accurately collect oral fluid, avoiding sample contamination or omission caused by animal movement, thus improving the accuracy of detection. At the same time, after the animal is fixed, the operator can focus more on sampling without having to control the animal, thereby improving efficiency.

[0038] Rotating rod 121 is connected to reciprocating lead screw 3 via transmission belt 2. Gear 122 meshes with gear 2 124. Sliding column 127 slides through machine body 1. The sides of push rod 129 and inclined block 1212 that are close to each other are both set as inclined surfaces. The transmission connection ensures that the reciprocating lead screw 3 can drive rotating rod 121 to rotate when it rotates. The meshing ensures that gear 122 can drive gear 2 124 to rotate when it rotates. The inclined surfaces ensure that push rod 129 can smoothly push inclined block 1212 when it moves.

[0039] The protective device includes a slide rail 131, a second inclined block 132, a limiting plate 133, a baffle 134, and a fixing block 135. The slide rail 131 is fixedly installed at the bottom of the machine body 1, the second inclined block 132 is fixedly installed at the bottom of the slide rail 131, the limiting plate 133 is fixedly installed on the left side of the collection drawer 1211, the baffle 134 is slidably installed on the top of the collection drawer 1211, and the fixing block 135 is fixedly installed on the top of the baffle 134. The process of gradually pushing out and opening the collection drawer 1211 is smoother, avoiding sudden movements that may frighten the animals and reduce their stress response. At the same time, the operation of pushing out and opening the collection drawer 1211 is more orderly, reducing the possibility of operational errors and repeated sampling, and improving overall efficiency.

[0040] The protective device also includes a collection box 136, a handle 137, a button 138, a ramp 139, and a limiting block 1310. The collection box 136 is slidably installed inside the collection drawer 1211. The handle 137 is fixedly installed at the front of the collection box 136. The button 138 slides through the handle 137. The ramp 139 is slidably installed at the front of the collection box 136. The limiting block 1310 is fixedly installed at the front of the collection drawer 1211. The ramp 139 contacts the limiting block 1310 to restrict the collection box 136, ensuring that the sampling device remains stable during operation and avoiding sampling errors caused by shaking or displacement. At the same time, preventing excessive movement of the collection box 136 can reduce the risk of accidental collisions or equipment damage during operation and protect the safety of operators and animals.

[0041] The slide rail 131 contacts the collection drawer 1211. The sides of the inclined block 132 and the fixed block 135 that contact each other are both set as inclined surfaces. The sides of the button 138 and the inclined rod 139 that contact each other are both set as inclined surfaces. A spring 1 is set between the button 138 and the collection box 136, and a spring 2 is set between the inclined rod 139 and the collection box 136. The contact ensures that the collection drawer 1211 can move along the designated track. The inclined surfaces ensure that the fixed block 135 can be pushed smoothly when it contacts the inclined block 132. The inclined surfaces ensure that the button 138 can push the inclined rod 139 smoothly when it moves. The spring 1 ensures that the button 138 can achieve self-reset. The spring 2 ensures that the inclined rod 139 can achieve self-reset.

[0042] In this embodiment, during operation: While the reciprocating lead screw 3 rotates, the transmission belt 2 drives the rotating rod 121 to rotate. The rotation of the rotating rod 121 drives the gear 122 to rotate, which in turn drives the gear 124 to rotate. The rotation of the gear 124 drives the threaded rod 123 to rotate, which in turn drives the sleeve 125 to move towards the gear 124. The movement of the sleeve 125 drives the sliding column 127 to move, which in turn drives the clamping rod 128 to move. The movement of the clamping rod 128 effectively controls the movement of the animal's head, preventing it from struggling or swaying, and ensuring the smooth progress of the sampling process. With the head secured, the operator can use the sampling device more precisely, reducing operation time and improving efficiency. As the clamping rod 128 moves, it drives the push rod 129 to move. The push rod 129 moves and contacts and pushes the inclined block 1212 to move. The movement of the inclined block 1212 drives the collection tray 1211 to move forward. After the animal is secured, the collection tray 1211 can be pushed out to accurately collect oral fluid, avoiding sample contamination or omission caused by animal movement, thus improving detection accuracy. At the same time, after the animal is secured, the operator can focus more on sampling without having to be distracted by controlling the animal, thereby improving efficiency.

[0043] As the collection drawer 1211 moves, the baffle 134 also moves. The movement of the baffle 134 causes the fixing block 135 to move, and the fixing block 135 contacts the inclined block 132, pushing the baffle 134 towards the limiting plate 133. The baffle 134 then opens the collection drawer 1211. This gradual opening and closing process is smoother, avoiding sudden movements that might startle the animal and reduce its stress response. The more orderly operation of opening and closing the collection drawer 1211 also reduces operational errors and the possibility of repeated sampling, improving overall efficiency. After collection is complete, the baffle 134 completely covers the collection drawer 1211. At this point, the operator manually presses button 138, which contacts and pushes the baffle 134. The inclined rod 139 begins to move downwards, disengaging from the limiting block 1310. Then, the operator manually pulls the handle 137 to remove the collection box 136 from the collection drawer 1211. After removal, the operator can extract oral fluid from the collection box 136 for testing. After cleaning the collection box 136, it is placed back into the collection drawer 1211. At this point, the inclined rod 139 contacts the limiting block 1310, restricting the collection box 136 and ensuring the stability of the sampling device during subsequent operations. This avoids sampling errors caused by shaking or displacement, and prevents excessive movement of the collection box 136, reducing the risk of accidental collisions or equipment damage during operation and protecting the safety of operators and animals.
