Technical Field

[0001] This invention belongs to the field of swine respiratory tract sampling technology, and relates to a tool for sampling swine respiratory pathogens. Background Technology

[0002] To facilitate health management of pig herds, it is necessary to collect respiratory secretions from pigs for pathogen detection. However, the current common sampling method relies on manual operation, such as using disposable pipettes or cotton swabs to collect secretions from the pigs' mouths and noses. This method requires manual control of the pigs throughout the sampling process, which is inconvenient and can easily cause stress to the pigs, posing a certain risk to their health. Summary of the Invention

[0003] In view of this, the present invention provides a tool for sampling respiratory pathogens in pigs to solve the problems mentioned in the background art, and specifically discloses the following:

[0004] A tool for sampling respiratory pathogens in pigs includes a cover, a spray collection component detachably connected to the middle of the front end of the cover, cough induction components provided on both sides of the front end of the cover, the spray collection component and the cough induction components facing the mouth and nose of the pig, and a fixing component provided around the periphery of the cover for fixing the cover to the mouth and nose of the pig.

[0005] Furthermore, the cough induction component includes a drive unit and a cough induction unit. Fixing blocks are fixedly installed on both sides of the front end of the cover. The cough induction unit includes a spray cylinder and a push rod. A liquid storage chamber is provided below the interior of each fixing block, and induction liquid is placed in the liquid storage chamber. The spray cylinder is fixedly installed above the interior of the fixing block. The liquid storage chamber is connected to the inner cavity of the spray cylinder through an outlet pipe. A second one-way valve is provided on the outlet pipe to restrict the induction liquid from flowing into the inner cavity of the spray cylinder only from the liquid storage chamber.

[0006] The fixed block has a guide groove at its upper interior. One end of the push rod is slidably connected to the guide groove, and the other end extends into the spray cylinder and is fixedly connected to a piston head. The piston head is adapted to the inner cavity of the spray cylinder. The fixed block and the cover have spray holes on their connecting wall. The spray cylinder has a nozzle at its end away from the push rod, and the nozzle is horizontally aligned with the spray hole. The nozzle has a first one-way valve to restrict the inducing liquid to be sprayed out only from the nozzle.

[0007] The drive unit is used to drive the push rod to move, draw up the inducing liquid in the storage chamber, and spray it outward through the nozzle.

[0008] Furthermore, the driving unit includes a pressing block and a first spring. Two driving rods are symmetrically arranged below the pressing block, and two first guide vertical grooves adapted to the driving rods are arranged above the fixing block. One end of the first spring is fixedly connected to the bottom end of the first guide vertical groove, and the other end is connected to the bottom wall of the driving rod. The first guide vertical groove communicates with the guide horizontal groove. A driving block is fixedly arranged below the driving rod on the side near the push rod.

[0030] See appendix Figure 1-6The present invention discloses a tool for sampling respiratory pathogens in pigs, including a cover 1. A spray collection component is detachably connected to the middle of the front end of the cover 1. Cough induction components are provided on both sides of the front end of the cover 1. Both the spray collection component and the cough induction component face the mouth and nose of the pig. Fixing components are provided around the cover 1 for fixing the cover 1 to the mouth and nose of the pig.

[0031] In this embodiment, a single penned pig is driven towards the feeding trough. Due to the narrow space, an object is placed behind the pig to drive it forward. At this time, the cover is fixed to the pig's mouth and nose by a fixing component. A cough induction component is activated to stimulate the pig to sneeze, and the spray collection component collects the spray to actively collect respiratory pathogens from the pig. The above sampling process does not require human control of the pig, saving labor, reducing the probability of stress on the pig, and minimizing harm to the pig.

[0032] The cough induction component includes a drive unit and a cough induction unit. Fixing blocks 5 are fixedly installed on both sides of the front end of the cover 1. The cough induction unit includes a spray cylinder 7 and a push rod 81. A liquid storage chamber 9 is provided at the lower part of the inside of the fixing block 5. The liquid storage chamber 9 contains induction liquid. The spray cylinder 7 is fixedly installed at the upper part of the inside of the fixing block 5. The liquid storage chamber 9 is connected to the inner cavity of the spray cylinder 7 through a liquid outlet pipe 91. A second one-way valve 911 is provided on the liquid outlet pipe 91 to restrict the induction liquid from flowing into the inner cavity of the spray cylinder 7 only through the liquid storage chamber 9.

[0033] The upper part of the fixed block 5 is provided with a guide groove 54. One end of the push rod 81 is slidably connected in the guide groove 54, and the other end is inserted into the spray cylinder 7 and fixedly connected with a piston head 82. The piston head 82 is adapted to the inner cavity of the spray cylinder 7. The connecting wall between the fixed block 5 and the cover 1 is provided with a spray hole 55. The end of the spray cylinder 7 away from the push rod 81 is provided with a nozzle 71. The nozzle 71 is horizontally aligned with the spray hole 55. The nozzle 71 is provided with a first one-way valve 711 to restrict the inducing liquid to be sprayed out only from the nozzle 71.

[0034] The drive unit is used to drive the push rod 81 to move, draw in the inducing liquid in the storage chamber 9, and spray it outward through the nozzle 71.

[0035] In this embodiment, a quantitative inducing liquid is stored between the piston head 82 and the nozzle 71 in the initial stage. The driving unit drives the push rod 81 to move, and the piston head 82 squeezes the inducing liquid, so that the inducing liquid is sprayed out from the nozzle 55. After the inducing liquid is sprayed out, the driving unit drives the push rod 81 to return to its original position and draws the inducing liquid in the storage chamber 9 under negative pressure.

[0036] The drive unit includes a pressing block 61 and a first spring 65. Two drive rods 62 are symmetrically arranged below the pressing block 61. Two first guide vertical grooves 51 that are adapted to the drive rods 62 are arranged above the fixing block 5. One end of the first spring 65 is fixedly connected to the bottom end of the first guide vertical groove 51, and the other end is connected to the bottom wall of the drive rod 62. The first guide vertical groove 51 is connected to the guide horizontal groove 54. A drive block 621 is fixedly arranged on the side of the drive rod 62 near the push rod 81. Drive grooves that are adapted to the drive block 621 are arranged on both sides of the push rod 81. When the drive rod 62 moves downward, it drives the push rod 81 to move closer to the nozzle 71.

[0037] In this embodiment, the experimental data on sneezing in pigs induced by the inducing solution are shown in the table below:

[0038]

[0039] As shown in the table above, the concentration and dosage of the inducing solution can ensure that the pigs will sneeze without causing harm. The specific inducing solution can be selected according to the actual situation.

[0040] In this embodiment, by driving the pressing block 61 downward, the driving rod 62 slides downward along the first guide vertical groove 51, compressing the first spring 65. The driving block 621 cooperates with the driving groove, thereby driving the push rod 81 to move closer to the nozzle 71. The piston head 82 squeezes the inducing liquid, causing the inducing liquid to be sprayed out from the spray hole 55. After the inducing liquid is sprayed out, the first spring 65 returns to its deformation, driving the push rod 81 to return to its original position. Under the action of negative pressure, the inducing liquid in the storage chamber 9 is sucked up.

[0041] A second guide groove 53 is also provided on the connecting wall between the fixing block 5 and the cover 1. The spray hole 55 passes through the middle position of the second guide groove 53. A baffle 64 is slidably provided in the second guide groove 53. A through hole 641 is provided on the baffle 64. A second spring 66 is fixedly provided on the bottom wall of the second guide groove 53. One end of the second spring 66 away from the bottom wall of the second guide groove 53 is fixedly connected to the bottom wall of the baffle 64.

[0042] A connecting rod 63 is fixedly connected to the top of the baffle 64. The end of the connecting rod 63 away from the baffle 64 is fixedly connected between two drive rods 62. An avoidance groove 52 adapted to the connecting rod 63 is provided inside the upper part of the fixing block 5. The avoidance groove 52 is connected to the second guide vertical groove 53.

[0043] The drive channel includes a vertical section 811 and an inclined section 812 connected from top to bottom. The drive block 621 slides from the beginning of the vertical section 811 to the end of the inclined section 812. The through hole 641 coincides with the spray hole 55. The piston head 82 squeezes the inducing liquid in the spray cylinder 7 to ensure that the inducing liquid is sprayed from the nozzle 71 onto the mouth and nose of the pig.

[0044] In this embodiment, the downward-driven pressing block 61 causes the driving rod 62 to slide downward along the first guide groove 51, compressing the first spring 65. The connecting plate 63 then moves the baffle 64 downward, compressing the second spring 66. The through hole 641 aligns with the spray hole 55. At this time, the driving block 621 slides along the vertical section 811, and the push rod 81 does not move. This continues until the driving block 621 slides to the inclined section 812, driving the push rod 81 to move closer to the nozzle 71. The piston head 82 then squeezes the inducing liquid, causing the inducing liquid to be sprayed out from the spray hole 55. The vertical length of the through hole 641 is greater than that of the spray hole 55, ensuring that the through hole 641 coincides with the spray hole 55 during the process of the drive block 621 sliding from the end of the vertical section 811 to the end of the inclined section 812. This ensures that the inducing liquid can be smoothly sprayed out from the spray hole 55. After the inducing liquid is sprayed out, the first spring 65 and the second spring 66 return to their original deformation, and the drive push rod 81 and the baffle 64 return to their original positions. Under the action of negative pressure, the inducing liquid in the storage chamber 9 is sucked up, and the baffle 64 isolates the spray hole 55 to prevent the pigs from sneezing and contaminating the nozzle 71.

[0045] The spray collection assembly includes a conical tube 3 detachably connected to the middle of the front end of the cover 1. A conical collection element 4 is placed inside the conical tube 3. The conical collection element 4 is used to collect respiratory pathogens in pigs.

[0046] In this embodiment, the inner side of the cone-shaped collection device 4 can be made of flocked cloth. After collecting respiratory pathogens from pigs, the cone-shaped cylinder 3 is disassembled and the cone-shaped collection device 4 is removed. After removal, the cover 1 can be placed in the equipped disinfection box for disinfection for the next use.

[0047] The fastening assembly includes a top strap 21, a first side strap 22, and a second side strap 23; one end of the top strap 21 is fixedly connected to the top of the cover 1, and the other end is provided with a first connecting ring 211; one end of the first side strap 22 is fixedly connected to one side of the cover 1, and the other end is provided with a second connecting ring 222, and a female Velcro 221 is provided on the first side strap 22 near the second connecting ring 222; one end of the second side strap 23 is fixedly connected to the other side of the cover 1, and the other end is provided with a male Velcro 231.

[0048] In this embodiment, the cover 1 is placed over the pig's mouth and nose, ensuring that there is a gap between the front end of the cover 1 and the pig's mouth and nose, so that the spray collection component and the cough induction component are facing the pig's mouth and nose. Then, the second side strap 23 is passed through the first connecting ring 211 and the second connecting ring 222, and the male Velcro 231 and the female Velcro 221 are connected to fix the cover 1.

[0049] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
