Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling device technology, and in particular to a pig saliva sampling device. Background Technology
[0002] Swine saliva sampling is an important technique for monitoring the health status of swine herds and diagnosing diseases. When sampling swine saliva, a sampling rope is hung on the fence of the pig farm, and the swine herd chews on the end of the rope for a period of time. Then, the end of the rope is pressed firmly to collect the saliva on the rope into a sample bag.
[0003] When collecting saliva from a rope, the usual method is to simply put the sample bag over the rope and then pull the sample bag across the rope's surface to squeeze out the saliva. This method may cause the sample bag to break during friction with the rope, resulting in saliva sample leakage and affecting sampling results and efficiency. Utility Model Content
[0004] The purpose of this invention is to address the problem that when collecting saliva from a rope, the usual method involves directly placing a sample bag over the rope and then pulling the bag to move it across the rope's surface to squeeze out the saliva. This method can lead to damage to the sample bag during friction with the rope, resulting in saliva sample leakage and affecting sampling results and efficiency. Therefore, this invention proposes a pig saliva sampling device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pig saliva sampling device, comprising a mounting plate, an arc-shaped plate fixedly connected to the top of the mounting plate, a hanging ring fixedly connected to one side of the arc-shaped plate, a sampling rope provided on the outer surface of the hanging ring, an auxiliary device provided on one side of the mounting plate to facilitate squeezing out saliva from the sampling rope, and a positioning device provided on the outer surface of the mounting plate to facilitate installing the sampling device on the pigpen fence.
[0006] The effect achieved by the above components is as follows: when using the sampling device to sample pig saliva, the mounting plate and the arc plate are installed on the pig pen fence with the help of the positioning device. Then, one end of the sampling rope is passed through the hanging ring on one side of the arc plate and tied with a knot. The end of the sampling rope that hangs down is torn into multiple strips, so that the pigs chew on the hanging end of the sampling rope for a period of time. Then, the saliva on the sampling rope is squeezed into the sampling bag for collection through the auxiliary device.
[0007] Preferably, the auxiliary device includes a ring, one side of which is fixedly connected to one side of the mounting plate, and L-shaped rods are fixedly connected to both sides of the ring. A round rod is slidably connected to the inner wall of the L-shaped rod and slides on the inner wall of the ring. A pressing block is fixedly connected to one end of the round rod, and a spring is provided on the outer surface of the round rod. The two ends of the spring are fixedly connected to one side of the round rod and one side of the ring, respectively.
[0008] The effect achieved by the above components is as follows: When installing the sampling device, one end of the sampling rope is passed through the inside of the ring and positioned between the two squeezing blocks. When collecting saliva on the sampling rope, the open end of the sampling bag is placed from bottom to top on the outside of the sampling rope and the ring. The two round rods are pinched on both sides of the outer surface of the sampling bag to control the two round rods to slide towards the middle on the inner wall of the ring and the L-shaped rod while holding the sampling bag. This causes the two squeezing blocks to press against the outer surface of the sampling rope. Then, the sampling rope is pulled upward with the other hand, so that the sampling rope rises between the two squeezing blocks. The saliva collected on the sampling rope is collected through the two squeezing blocks and enters the inside of the sampling bag.
[0009] Preferably, the diameter of the round rod is slightly smaller than the inner diameter of the spring, and the spring is located on the outside of the round rod.
[0010] The effect achieved by the above components is that when the spring is deformed by pushing the round rod, the spring will move on the outside of the round rod. The round rod can reinforce the internal shape of the spring and minimize the lateral deformation of the spring that may affect normal use.
[0011] Preferably, a groove block is fixedly connected to the end of the round rod away from the extrusion block, and a groove is formed on one side of the groove block.
[0012] The effect achieved by the above components is that pinching the groove on the outer surface of the slot block makes it easier to control the movement of the round rod and prevents it from slipping.
[0013] Preferably, a protruding rod is fixedly connected to one side of the top end of the extrusion block. The outer surface of the protruding rod is tapered, and the top end of the protruding rod protrudes from the side of the extrusion block away from the round rod.
[0014] The effect achieved by the above components is that when the squeezing block is pressed against the outer surface of the sampling rope and the sampling rope is pulled, the squeezing sampling effect on the surface of the sampling rope can be improved by the conical protrusion.
[0015] Preferably, the positioning device includes a screw, the outer surface of which is threaded to the bottom of the inner wall of the mounting plate, and a sliding plate is rotatably connected to the top of the screw, one side of which slides on one side of the mounting plate.
[0016] The effect achieved by the above components is as follows: When installing the sampling device, the mounting plate and the arc-shaped plate are respectively clipped onto one side and the top of the pigpen fence, so that the top of the inner wall of the arc-shaped plate is attached to the surface of the fence. Then, the screw is rotated to control the screw to move upward on the inner wall of the mounting plate, pushing one side of the sliding plate to slide upward on one side of the mounting plate, so that the top of the sliding plate is pressed against the bottom of the fence, thus fixing the position of the mounting plate and the arc-shaped plate on the outer surface of the fence. After sampling is completed, the screw is rotated to control the sliding plate to move away from the outer surface of the fence, and then the mounting plate and the arc-shaped plate can be removed to disassemble the sampling device.
[0017] Preferably, L-shaped blocks are fixedly connected to both sides of the sliding plate, and one side of the L-shaped block slides on one side of the mounting plate.
[0018] The effect achieved by the above components is that when the rotating screw controls the movement of the sliding plate, the L-shaped blocks on both sides of the sliding plate will slide on both sides of the mounting plate. The L-shaped blocks can further limit the angle between the sliding plate and the mounting plate, and minimize the deviation of the sliding plate angle when it moves.
[0019] Preferably, an operating block is fixedly connected to the bottom end of the screw, and the outer surface of the operating block is provided with several protrusions.
[0020] The effect achieved by the above components is that the protrusions on the outer surface of the operating block make it easier to rotate the operating block to control the screw rotation and prevent the hand from slipping.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting an auxiliary device, when collecting saliva from the sampling rope, the sampling bag is placed over the outer surface of the ring and the sampling rope, the two round rods are pinched to squeeze the outer surface of the sampling rope, and the sampling rope is pulled upward to squeeze out the saliva collected inside the sampling rope. This eliminates the need to pinch the sampling bag on the surface of the sampling rope to collect the saliva, thus minimizing the risk of damage to the sampling bag during the sampling process and improving the flexibility, convenience, and sampling efficiency of the sampling device.

[0028] Example 1, as Figure 1-2 As shown, a pig saliva sampling device includes a mounting plate 1, an arc-shaped plate 4 fixedly connected to the top of the mounting plate 1, a hanging ring 5 fixedly connected to one side of the arc-shaped plate 4, a sampling rope 6 provided on the outer surface of the hanging ring 5, an auxiliary device 2 provided on one side of the mounting plate 1 to facilitate squeezing out the saliva on the sampling rope 6, and a positioning device 3 provided on the outer surface of the mounting plate 1 to facilitate installing the sampling device on the pigpen fence. When using the sampling device to sample pig saliva, the mounting plate 1 and the arc-shaped plate 4 are installed on the pigpen fence with the help of the positioning device 3. Then, one end of the sampling rope 6 is passed through the hanging ring 5 on one side of the arc-shaped plate 4 and tied with a knot. The end of the sampling rope 6 that hangs down naturally is torn into multiple strips, allowing the pigs to chew on the hanging end of the sampling rope 6 for a period of time. Then, the saliva on the sampling rope 6 is squeezed into the sampling bag for collection through the auxiliary device 2.
[0029] Reference Figure 1-4As shown in this embodiment: the auxiliary device 2 includes a ring 21, one side of which is fixedly connected to one side of the mounting plate 1. L-shaped rods 22 are fixedly connected to both sides of the ring 21. A round rod 23 is slidably connected to the inner wall of the L-shaped rod 22, sliding on the inner wall of the ring 21. A squeezing block 25 is fixedly connected to one end of the round rod 23. A spring 24 is provided on the outer surface of the round rod 23, with both ends of the spring 24 fixedly connected to one side of the round rod 23 and one side of the ring 21, respectively. By setting the squeezing block 25, when installing the sampling device, one end of the sampling rope 6 passes through the inside of the ring 21 and is positioned between the two squeezing blocks 25. When collecting saliva from the sampling rope 6, the open end of the sampling bag is placed from bottom to top on the outside of the sampling rope 6 and the ring 21. The two round rods 23 are pinched on both sides of the outer surface of the sampling bag to control their movement within the ring 21 and the ring 22. The inner wall of the L-shaped rod 22 slides towards the center and simultaneously holds the sampling bag, causing the two squeezing blocks 25 to press against the outer surface of the sampling rope 6. Then, the other hand pulls the sampling rope 6 upward, causing it to rise between the two squeezing blocks 25. The saliva collected on the sampling rope 6 is collected by the two squeezing blocks 25 and enters the sampling bag. By setting the auxiliary device 2, when collecting saliva on the sampling rope 6, the sampling bag is placed over the outer surface of the ring 21 and the sampling rope 6. The two round rods 23 are pinched to make the squeezing blocks 25 press against the outer surface of the sampling rope 6, and the sampling rope 6 is pulled upward to squeeze out the saliva collected inside the sampling rope 6. It is not necessary to pinch the sampling bag against the surface of the sampling rope 6 to collect the saliva. This avoids damage to the sampling bag during the sampling process as much as possible and improves the flexibility, convenience and efficiency of the sampling device.
[0030] Reference Figure 2-4 As shown in this embodiment: the diameter of the round rod 23 is slightly smaller than the inner diameter of the spring 24. The spring 24 is located outside the round rod 23. When the round rod 23 is pushed to move and the spring 24 is deformed, the spring 24 will move outside the round rod 23. The round rod 23 can reinforce the internal shape of the spring 24 and avoid lateral deformation of the spring 24 as much as possible, which would affect normal use. The end of the round rod 23 away from the extrusion block 25 is fixedly connected to the groove block 26. A groove 27 is provided on one side of the groove block 26. Pinching the groove 27 on the outer surface of the groove block 26 can more conveniently control the movement of the round rod 23 and prevent it from slipping.
[0031] Reference Figure 2-4 As shown in this embodiment: a protruding rod 28 is fixedly connected to one side of the top of the extrusion block 25. The outer surface of the protruding rod 28 is conical. The top of the protruding rod 28 protrudes from the side of the extrusion block 25 away from the round rod 23. When the extrusion block 25 is pressed against the outer surface of the sampling rope 6 and the sampling rope 6 is pulled, the extruding rod 28 can improve the extrusion sampling effect on the surface of the sampling rope 6.
[0032] Reference Figure 1-3 As shown in this embodiment: the positioning device 3 includes a screw 31, the outer surface of which is threadedly connected to the bottom of the inner wall of the mounting plate 1. A sliding plate 32 is rotatably connected to the top of the screw 31. One side of the sliding plate 32 slides on one side of the mounting plate 1. When installing the sampling device, the mounting plate 1 and the arc plate 4 are respectively clamped on one side and the top of the pigpen fence, so that the top of the inner wall of the arc plate 4 is attached to the surface of the fence. Then, the screw 31 is rotated to control the screw 31 to move upward on the inner wall of the mounting plate 1, pushing one side of the sliding plate 32 to slide upward on one side of the mounting plate 1, so that the top of the sliding plate 32 is pressed against the bottom of the fence, and the positions of the mounting plate 1 and the arc plate 4 on the outer surface of the fence are fixed. After sampling is completed, the screw 31 is rotated to control the sliding plate 32 to move away from the outer surface of the fence, and then the mounting plate 1 and the arc plate 4 are removed to remove the sampling device.
[0033] Reference Figure 2-3 As shown in this embodiment: L-shaped blocks 33 are fixedly connected to both sides of the sliding plate 32. One side of the L-shaped block 33 slides on one side of the mounting plate 1. When the screw 31 is rotated to control the movement of the sliding plate 32, the L-shaped blocks 33 on both sides of the sliding plate 32 will slide on both sides of the mounting plate 1. The angle between the sliding plate 32 and the mounting plate 1 can be further restricted by the L-shaped blocks 33, so as to avoid the angle of the sliding plate 32 from deflecting when it moves as much as possible. An operating block 34 is fixedly connected to the bottom end of the screw 31. Several protrusions are provided on the outer surface of the operating block 34. Holding the protrusions on the outer surface of the operating block 34 makes it easier to rotate the operating block 34 to control the rotation of the screw 31 and prevents the hand from slipping.
[0034] Working principle: When sampling pig saliva using the sampling device, the mounting plate 1 and the arc-shaped plate 4 are respectively attached to one side and the top of the pigpen fence, so that the top of the inner wall of the arc-shaped plate 4 is in contact with the fence surface. Then, the screw 31 is rotated to control the screw 31 to move upward on the inner wall of the mounting plate 1, pushing one side of the sliding plate 32 to slide upward on one side of the mounting plate 1, so that the top of the sliding plate 32 is pressed against the bottom of the fence, fixing the position of the mounting plate 1 and the arc-shaped plate 4 on the outer surface of the fence. Then, one end of the sampling rope 6 is passed through the hanging ring 5 on one side of the arc-shaped plate 4 and tied with a knot. The end of the sampling rope 6 that hangs naturally is passed through the circular ring 21 and torn into multiple strips, allowing the pigs to chew on the hanging end of the sampling rope 6 for a period of time, collecting the saliva on the sampling rope 6. During sampling, the open end of the sampling bag is placed over the outside of the sampling rope 6 and the ring 21 from bottom to top. Two round rods 23 are pinched on either side of the outer surface of the sampling bag, controlling them to slide towards the center along the inner walls of the ring 21 and the L-shaped rod 22 while simultaneously holding the sampling bag. This causes the two squeezing blocks 25 to press against the outer surface of the sampling rope 6. Then, the other hand is used to pull the sampling rope 6 upwards, allowing it to rise between the two squeezing blocks 25. The saliva collected on the sampling rope 6 is then collected through the two squeezing blocks 25, allowing it to enter the sampling bag and complete the sampling. After sampling, the screw 31 is rotated to move the sliding plate 32 away from the outer surface of the railing. The mounting plate 1 and the arc-shaped plate 4 can then be removed to detach the sampling device.
