Abstract
Description
Technical Field
[0001] This utility model relates to the field of sample collection devices, specifically a sample collection device for veterinary testing. Background Technology
[0002] Animal husbandry provides society with a wealth of livestock products, such as meat, eggs, milk, and fur, satisfying people's daily demand for animal-based foods and leather products.
[0003] Livestock farming typically involves group rearing with close contact between animals. If one animal contracts an infectious disease, it can easily spread rapidly to other animals, triggering a large-scale outbreak. Therefore, livestock farming requires animal testing, such as detecting antibody levels for infectious diseases to understand the herd's immune status and assess the risk of new disease introductions; detecting the presence of specific pathogens allows for timely isolation of sick animals, enabling the implementation of control measures such as disinfection and emergency immunization, cutting off disease transmission routes, and preventing the spread of disease within the herd and between different farms.
[0004] To inspect livestock herds, it is usually necessary to collect animal samples for testing. Currently, the required test samples include blood samples, tissue samples, secretion samples, and excrement samples. The excrement samples mentioned above mainly include fecal samples and urine samples. Fecal samples are commonly used to detect intestinal parasites and intestinal pathogens.
[0005] When collecting fecal samples, fresh feces naturally excreted by animals can be collected directly. Select the middle portion and place it in a clean, sterile sampling container. If testing for parasite eggs is required, multiple fecal samples can be collected, mixed, and sent for testing. When collecting fresh feces, the complex farming environment, including the mixing of feces with urine and other contaminants, makes it difficult to collect uncontaminated fecal samples, thus affecting the accuracy of the test results.
[0006] Therefore, to improve the accuracy of fecal testing, rectal sampling (especially for large animals such as cattle) can be used. The animal is first restrained, and the sampler, wearing gloves and lubricated, slowly inserts their arm and hand into the rectum to obtain a fecal sample. While this method allows for the collection of uncontaminated samples, for larger animals like cattle, the sampler's arm must be inserted into the rectum, and their face may even be close to the animal's anus, which could have a negative psychological impact on the sampler.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0035] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:
[0036] Example 1
[0037] To avoid discomfort for sampling personnel when collecting fecal samples from large animals such as cattle, this embodiment improves the fecal collection device for large animals. This device can be inserted into the rectum of large animals, and the fecal samples can be collected by the sampling personnel. This changes the method of directly inserting an artificial arm for collection, and relatively improves the comfort of fecal sample collection.
[0038] like Figure 3 Specifically, the collection device includes a sampling mechanism 3, a support and drive mechanism 1, etc.
[0039] like Figure 5 As shown, the sampling mechanism 3 includes a storage shell 32 and a spiral conveying shaft 31. One end of the storage shell 32 is open, and the spiral conveying shaft 31 is located inside the storage shell 32. The central shaft of the spiral conveying shaft 31 is connected to the end of the storage shell 32 via a bearing, and the end of the spiral conveying shaft 31 protrudes from the opening of the storage shell 32. With this configuration, after the storage shell 32 is inserted into the rectum of a large animal, rotating the spiral conveying shaft 31 forces feces near the opening of the storage shell 32 to move into the storage shell 32, thereby achieving the collection and processing of fecal samples. To facilitate the expulsion of gas from inside the storage shell 32, a second vent 35 is provided at the edge of the end of the storage shell 32. Therefore, during the process of feces moving into the storage shell 32, gas is discharged through the second vent 35.
[0040] like Figure 4 As shown, in order to control the movement of the storage shell 32 and facilitate the rotation of the screw conveyor shaft 31, the support drive mechanism 1 includes a first flexible shaft 11 and a second flexible shaft 12. The first flexible shaft 11 is set as a hollow structure. Therefore, the second flexible shaft 12 is set through the first flexible shaft 11. That is, the sampling personnel can simultaneously adjust the position of the first flexible shaft 11 and the second flexible shaft 12 by pushing and pulling the first flexible shaft 11, or rotate the second flexible shaft 12 independently to provide support for controlling the movement of the storage shell 32 and the rotation of the screw conveyor shaft 31.
[0041] like Figure 4 , Figure 5 As shown, specifically, an end tube 33 is fixedly provided at the center of the end of the storage shell 32, and a connecting tube 13 is fixedly provided at the end of the first flexible shaft 11. The connecting tube 13 can be sleeved on the end tube 33 by means of a bearing or by means of a bolt, so as to achieve a stable connection between the first flexible shaft 11 and the storage shell 32.
[0042] like Figure 4 , Figure 5As shown, the end face of the second flexible shaft 12 located inside the connecting tube 13 is provided with a polygonal groove, and the end of the central shaft of the screw conveyor shaft 31 is fixedly provided with a polygonal shaft 34. The polygonal shaft 34 is connected by bolts and inserted into the polygonal groove to achieve a stable connection between the second flexible shaft 12 and the central shaft of the screw conveyor shaft 31, thereby controlling the rotation of the screw conveyor shaft 31 when the second flexible shaft 12 rotates.
[0043] To control the rotation of the second flexible shaft 12, its other end protrudes from the first flexible shaft 11, and a rotating wheel 14 is fixedly installed at the protruding end of the second flexible shaft 12. To facilitate support of the first flexible shaft 11 by the sampling personnel, a handrail 15 is fixedly installed at the other end of the first flexible shaft 11. When using this device to collect fecal samples from large animals, the storage shell 32 is inserted into the rectum, and the first flexible shaft 11 and the storage shell 32 are moved by holding the handrail 15. Once the storage shell 32 has moved to the appropriate position, the sampling personnel control the rotating wheel 14 to rotate, which in turn drives the spiral conveyor shaft 31 to rotate, forcing the feces near the opening of the storage shell 32 to move into the storage shell 32.
[0044] Example 2
[0045] like Figure 1 , Figure 2 , Figure 6 As shown, based on Example 1, in order to disinfect the sample collection device to complete the next collection task, a disinfection component is provided. This disinfection component includes a housing 4 and a disinfection mechanism 2. The housing 4 can be fitted onto the outside of the storage shell 32, with a gap between the housing 4 and the storage shell 32. One end of the disinfection mechanism 2 is located on the outside of the housing 4, and the other end extends into the gap formed by the housing 4 and the storage shell 32. Therefore, after collecting and cleaning the sample, the sampling mechanism 3 is placed inside the housing 4, and activating the disinfection mechanism 2 can raise the temperature inside the housing 4, achieving high-temperature disinfection of the sampling mechanism 3.
[0046] like Figure 9 As shown, in order to increase the temperature inside the housing 4, the disinfection mechanism 2 includes an air pump 23, an air exchange device 22, and multiple heating rods 21.
[0047] like Figure 11 As shown, the ventilation device 22 includes an end plate 223, which is installed at an opening at one end of the housing 4. Multiple heating rods 21 are disposed inside the housing 4, adjacent to the sidewalls of the housing 4, and evenly distributed along the circumference of the housing 4, i.e., within the gap between the housing 4 and the storage shell 32. The ends of the heating rods 21 penetrate the end plate 223, and their wires are connected to a control box outside the housing 4. Therefore, the operation of multiple heating rods 21 can be controlled via the control box.
[0048] Heating rod 21 is existing publicly available technology, and a brief introduction is provided here. It includes a heating wire, a housing, and a thermostat. The heating wire is located inside the housing, and the sidewalls of the heating wire are lined with insulating materials such as magnesium oxide powder. The thermostat can be located at the end of the housing to connect the wire to the heating wire.
[0049] like Figure 11 As shown, to facilitate the entry of high-temperature gas into the storage shell 32 and achieve rapid disinfection of the sampling mechanism 3, the ventilation device 22 also includes a support ring plate 221, a filling plate 222, and an annular convex plate 224. The support ring plate 221 is detachably connected by bolts and fitted to the side of the end plate 223. The filling plate 222 is installed inside the support ring plate 221, and the thickness of the filling plate 222 is less than the thickness of the support ring plate 221. The filling plate 222 is located on the side of the support ring plate 221 away from the end plate 223, thus forming a cavity space between the filling plate 222, the support ring plate 221, and the end plate 223. The annular convex plate 224 is installed on the side of the end plate 223 away from the support ring plate 221, and the diameter of the annular convex plate 224 is smaller than the diameter of the end plate 223. The inner diameter of the annular convex plate 224 is equal to the outer diameter of the filling plate 222.
[0050] When the storage shell 32 is installed inside the housing 4, its end contacts the annular protrusion 224, while the end of the screw conveyor shaft 31 extends into the slot 225. This creates two spaces on the inner and outer sides of the storage shell 32. To connect these two spaces, a first air hole 226 is provided on the side wall of the end plate 223, located inside the annular protrusion 224. This arrangement forms a gas flow channel, allowing gas in the gap between the storage shell 32 and the housing 4 to flow into the cavity space. Gas in the cavity space flows into the storage shell 32 through the first air hole 226, and gas in the storage shell 32 can flow into the gap between the storage shell 32 and the housing 4 through the second air hole 35. Therefore, the gas heated by the heating rod 21 circulates within and outside the storage shell 32, providing support for the rapid disinfection of the storage shell 32 and the screw conveyor shaft 31. When the storage shell 32 is installed in the housing 4, the snap-fit end of the first flexible shaft 11 is attached to the first snap-fit arc plate 41.
[0051] The aforementioned support ring plate 221 can be configured as a cavity structure. In this case, the temperature controller of the heating rod 21 is installed in the cavity of the support ring plate 221, so that the temperature controllers of multiple heating rods 21 are connected in parallel, and then connected to the control box.
[0052] like Figure 9 , Figure 10As shown, to control the gas circulation within the housing 4, an air pump 23 is positioned on the side of the support ring plate 221 away from the end plate 223. An input pipe 232 is connected to the air inlet of the air pump 23, and an output pipe 231 is connected to its outlet. The end of the output pipe 231 is connected to the filling plate 222, thus communicating with the cavity space. The input pipe 232 passes through the edges of the support ring plate 221 and the end plate 223, extending into the gap between the storage shell 32 and the housing 4, forcing the gas within the housing 4 to circulate under the action of the air pump 23. Furthermore, the air pump 23 is connected to a control box.
[0053] The control box has also been disclosed, and a brief introduction is provided here. It includes circuit breakers, residual current devices (RCDs), power transformers, contactors, relays, and controllers (such as PLCs). The power cords of the air pump 23 and heating rod 21 are connected to the corresponding terminals inside the control box, allowing control of the air pump 23 and heating rod 21.
[0054] like Figure 8 As shown, to ensure the storage shell 32 and heating rod 21 are stably installed inside the housing 4, a second snap-fit arc plate 42 is fixedly provided on the inner side of the housing 4 away from the end plate 223. Multiple second snap-fit arc plates 42 are evenly distributed along the circumference of the housing 4 and snap onto multiple heating rods 21 respectively. A baffle 43 is provided on the inner side of the housing 4. At least two baffles 43 are provided, and the two baffles 43 must be located at opposite ends of the same diameter. The baffles 43 must be fitted against the storage shell 32; only under these conditions can the storage shell 32 be stably placed.
[0055] Example 3
[0056] like Figure 6 , Figure 7 As shown, based on embodiment 1 or 2, in order to realize the recycling of hot gas, a closed plate assembly 5 can be provided at the end of the housing 4 away from the air pump 23. The closed plate assembly 5 includes a first plate 51 and a second plate 53. The plug-in post 52 installed on the first plate 51 is inserted into the second plate 53 to realize the detachable connection between the first plate 51 and the second plate 53, which facilitates the fitting of the closed plate assembly 5 onto the first flexible shaft 11 and the installation on the housing 4.
[0057] like Figure 6 , Figure 7As shown, specifically, multiple retaining plates 44 are fixedly arranged on the inner side of the housing 4 away from the end plate 223, and the multiple retaining plates 44 are evenly distributed along the circumference of the housing 4. Inlet / outlet grooves 54 are provided on the edges of the first plate 51 and the second plate 53, and each inlet / outlet groove 54 has a connecting groove 55. The retaining plates 44 can pass through the inlet / outlet grooves 54 and be installed in the grooves 55. Therefore, with the cooperation of the grooves 55 and the retaining plates 44, the first plate 51 and the second plate 53 can be stably fixed on the housing 4. Arc-shaped grooves are provided in the middle of the first plate 51 and the second plate 53 near their respective side walls, and the first flexible shaft 11 passes through the space formed by the two arc-shaped grooves. Therefore, when the first plate 51 and the second plate 53 are fixedly installed, the storage shell 32 is effectively prevented from being stably placed inside the housing 4. Whether or not air holes are provided on the first plate 51 and the second plate 53 can be determined according to actual needs.
[0058] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
