Description

Technical Field

[0001] This invention relates to the field of healthy pig farming, specifically to a portable pig disease detection device. Background Technology

[0002] Saliva is one of the important body fluids in pigs and is commonly used as a sample for body fluid testing. However, existing methods for collecting saliva from pig herds are rather cumbersome. In livestock production, serum collection is difficult to complete for individuals with higher body weight and larger body size. Therefore, we collect saliva and test relevant physiological indicators to reflect the individual's condition. Compared with blood collection, this method is less stressful, cheaper, and more efficient, and does not require syringes or sterilization equipment, saving livestock farms a significant amount of manpower and resources.

[0003] However, there are currently no suitable tools for collecting swine saliva. Commonly, hand-sewn defatted cotton balls wrapped in gauze are used for collection. The collector then squeezes the saliva out by hand and collects it into a sample tube. This method yields relatively little saliva, requiring multiple collections to obtain sufficient amounts. Furthermore, this indirect method is prone to contamination, resulting in low sample quality. Additionally, because the tubes are located in a fixed spot within the pigpen, they are susceptible to damage by the pigs, making collection impossible.

[0004] Existing patents have also improved upon traditional collection methods. For example, patent CN215191804U describes a device for quickly collecting saliva from pigs. It includes a base 1 and a silicone ball 2. An absorbent sponge 3 is movably installed inside the silicone ball 2. A connector 4 is embedded inside the silicone ball 2. A vertical rod 5 is fixedly installed inside the connector 4. A handle 6 is fixedly installed at one end of the vertical rod 5. A collection cover 101 is fixedly installed on the upper surface of the base 1 near the center. A sampling bottle 102 is movably installed inside the collection cover 101. A bowl-shaped cavity 103 is opened on the outer surface of the collection cover 101. A threaded ring 401 is fixedly installed on the upper surface of the connector 4 near the center. The threaded ring 401 is threadedly connected to the lower end of the outer surface of the vertical rod 5. A spring 501 is nested on the outer surface of the vertical rod 5. A compression cover 502 is fixedly installed on the lower surface of the vertical rod 5.

[0005] However, based on discussions with pig farmers and on-site collection experiments, it has been determined that using silicone balls and absorbent sponges (or silicone balls and cotton balls, etc.) to collect very little saliva during pig biting is effective. Most of the saliva is either swallowed by the pig's bite or flows out of its mouth. When the pig releases its bite, the amount of saliva that can be collected is extremely small. In other words, the saliva on the silicone balls and absorbent sponges is swallowed or flows out of the mouth after being squeezed by the bite, resulting in very little subsequent collection. This amount is insufficient for testing. Therefore, the existing silicone balls and absorbent sponges, along with the subsequent collection device, cannot achieve saliva collection for disease detection. The same problem exists in patent CN112754535A, where the amount collected at the front end is very small, making it almost impossible to collect saliva using only squeezing. Based on these technical problems, when saliva-based disease detection is required, the existing collection methods need to be improved. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] In this invention, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms in this invention according to the specific circumstances.

[0041] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0042] This invention discloses a portable swine disease detection device, such as... Figure 1 As shown, the detection device is rod-shaped and has a collection head 1 and a handheld component 2.

[0043] like Figure 2 As shown, the sampling head 1 has a spherical shell 3 and a sampling device 13 disposed inside the spherical shell 3. To facilitate cleaning of the spherical shell 3 and the sampling device 13 after sampling, the sampling device 13 and the spherical shell 3 are detachable. To facilitate the placement and removal of the sampling device 13, the sampling head 1 has two semi-circular spherical shells 3.

[0044] like Figure 3 As shown, two spherical shells 3 are connected at one end by a hinge joint 4, and a threaded head 6 is provided at the other end. When the threaded heads 6 on the two spherical shells 3 are combined, they form a single threaded head assembly. Figures 2 to 3 The state shown.

[0045] Multiple through holes 5 are evenly distributed on the spherical shell 3 to provide an active suction port for the collection device 13. The collection device 13 of the present invention can suck up in any direction inside the spherical shell 3. Therefore, the through holes 5 should be evenly distributed on the surface of the spherical shell 3 as much as possible. In order to reduce the suction force of the collection device 13, the minimum diameter of the through holes 5 should be greater than 1 / 20 of the diameter of the spherical shell 3, and the maximum diameter should facilitate the movement of the collection device 13. The maximum diameter is designed according to the actual situation.

[0046] The handheld component 2 has a straight rod 7. One end of the straight rod 7 is provided with a ball head 8 and a ball head seat 9 that are connected to each other. The ball head 8 can rotate within the ball head seat 9, enabling the collection head 1 to rotate at multiple angles. This is beneficial for placing it inside the pig's mouth. Even if the pig shakes its head or makes other movements during collection, it can still be held well and will not be shaken off from the hand.

[0047] The straight rod 7 is fixedly connected to the ball head 8, and a connector 10 is fixedly connected to the ball head seat 9. The connector 10 has an internal thread, and a handle 11 is provided on the other end of the straight rod 7. The handle 11 is provided with anti-slip protrusions 12. When the two ball shells 3 are closed, the connector 10 is connected to the threaded head 6 to fix the two ball shells 3.

[0048] To address the issue of insufficient sample collection in existing technologies, the spherical shell 3 of this invention is made of a hard material, such as metal or hard plastic, but a soft pad is wrapped around the outer surface of the spherical shell 3 to protect the pig's mouth.

[0049] The acquisition device 13 is installed inside the acquisition head 1, such as Figure 4As shown, the collection device 13 has a walking mechanism 14, a suction device 15, and a rotating mechanism 16. The walking mechanism 14 is used to support the collection device 13 inside the spherical shell 3. The rotating mechanism 16 is fixed on both sides of the suction device 15 and is supported on the walking mechanism 14. The suction device 15 can be rotated by the rotating mechanism 16, thereby enabling the collection device to actively suction in any direction inside the spherical shell 3, thus improving the collection volume.

[0050] In one embodiment of the present invention, such as Figure 4 As shown, the walking mechanism has a vehicle body 17, on which walking wheels 19 are mounted. A motor compartment 18 is located above the vehicle body 17, and a walking motor is housed within the motor compartment 18. The output shaft of the walking motor drives the walking wheels 19 to rotate via a sprocket 20 and a chain 21, thereby causing the collection device 13 to rotate inside the spherical shell 3. In this embodiment, the walking mechanism of the present invention places the chain outside the vehicle body. Firstly, because the collection device is integrally housed within the spherical shell, the position of the chain will not affect the pig's oral cavity. Secondly, placing it externally facilitates cleaning after collection.

[0051] In one embodiment of the present invention, such as Figure 5 As shown, the rotating mechanism 16 has a housing 22, and a rotating shaft 23 is provided inside the housing 22. The rotating shaft 23 is rotatably mounted by a first bearing seat 24 fixed on the housing 22 and a second bearing seat 25 fixed on the outer wall of the suction device 15. The rotating shaft 23 passes through the housing 22 and is fixed to the outside of the motor compartment 18. A driven gear 26 is provided on the rotating shaft 23, and the driven gear 26 meshes with a drive gear 28 on the output shaft of the drive motor 27 fixed on the outer wall of the suction device 15.

[0052] In one embodiment of the present invention, such as Figure 6 As shown, the suction device 15 has a main housing 29, and a suction head 30 is provided at the upper end of the main housing 29. The suction head 30 has multiple suction holes 31, which are used to mate with through holes 5 on the spherical shell 3. Figure 8 , 9 As shown, a bottom cover 32 is provided at the bottom of the main housing 29. The bottom cover 32 has a cover body 33, and hinge shafts 34 are provided on both sides of the cover body 33. A recess 35 is provided on the outer side of the end of the cover body 33 opposite to the hinge shaft 34. A micro pump 36 is provided inside the main housing 29. One end of the micro pump 36 is connected to the suction head 30 through the front suction tube 37, and the other end of the micro pump 36 is connected to the discharge tube 38. A collection bottle 42 is also provided inside the main housing 29. The collection bottle 42 is used to receive the saliva discharged from the discharge tube 38.

[0053] like Figure 7As shown, in order to facilitate the installation of the collection bottle 42 and reduce the tediousness of straight alignment during installation, a docking device is provided between the discharge pipe 38 and the collection bottle 42.

[0054] In one embodiment of the present invention, the docking device includes a guide cylinder 40, which is fixed inside the main housing 29 by a support block 39. The main housing 29 is provided with a fixing seat 48 (hemispherical), a hose 49 and a support ring 50. One end of the hose 49 is fixed to the fixing seat 48 and the other end is fixed to the support ring 50. The discharge pipe 38 is connected to one end of the hose 49, and the other end of the hose 49 passes through the support ring 50 and is connected to the drain nozzle 41. A spring 51 is sleeved on the outside of the hose 49. One end of the spring 51 is fixed to the fixing seat 48 and the other end is fixed to the support ring 50. The drain nozzle 41 docks with the collection bottle 42.

[0055] like Figure 10 , 11 As shown in Figure 12, a groove 58 is provided on the upper part of the bottle body 56 of the collection bottle 42, below the bottle mouth 57. A locking device 43 is provided inside the main housing 29. The locking device 43 includes a support column 52 fixed to the inner side wall of the main housing 29 and a locking connector 53. The locking connector 53 is connected to a sliding rod 54. A compression spring 55 is sleeved on the outer side of the support column 52. One end of the compression spring 55 is fixed to the inner side wall of the main housing 29, and the other end is fixed to the locking connector 53. The locking connector 53 is used to lock into the groove 58. In order to facilitate the disassembly of the collection bottle 42, openings 46 are provided on both sides of the main housing 29. A lever 44 is provided in the opening 46. The lever 44 is hinged to the inner wall of the main housing 29. One end of the lever 44 extends through the opening 46, and a tension spring 45 is connected to the other end of the lever 44. The upper end of the tension spring 45 is fixed to the outer wall 47 of the guide cylinder 40.

[0056] The innovative structure of the present invention has been described above. In the present invention, the detection device is also equipped with a controller, which is used to control the motor compartment, drive motor, micro pump, etc., thus forming a complete acquisition and detection system.

[0057] During collection, insert the collection bottle into the suction device, aligning the bottle opening with the drain nozzle; place the cleaned and dried collection device into the spherical shell, close the shell, and connect the connector to the shell; control the motor compartment, drive motor, and micro pump using a handheld device or a controller mounted on the handle; the collection device rotates inside the collection head to collect saliva from the pig's mouth; when collection is complete (which can be counted using a flow meter mounted on the drain nozzle), open the bottom cover and move the lever to disengage the collection bottle from the locking device; finally, test the saliva in the collection bottle using a test kit.

[0058] Finally, it should be stated that, in order to solve the problems existing in the prior art, the present invention improves the existing structure. In order to enable the present invention to collect and detect saliva, all other contents not described in the present invention adopt the solutions already existing in the prior art.
