[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0022] like Figures 1 to 7As shown in the figure, an embodiment of the present invention proposes a microbial sampling and culture device for veterinary testing, comprising: a base 1, a flow guiding chamber 27 and a culture tank 2. The surface of the base 1 is provided with a plurality of flow guiding chambers 27, and the side of the flow guiding chamber 27 is provided with a culture tank 2. A culture mechanism 3 is placed inside the culture tank 2. The culture mechanism 3 is used to inject the collected microbial sample, and the culture mechanism 3 moves translationally along the inside of the culture tank 2. The culture device also includes a pushing mechanism 5, a mixing component 6, and a conveying pipe 4. The end of the flow guide chamber 27 is connected to the conveying pipe 4, the top of the conveying pipe 4 is connected to the mixing component 6, the end of the mixing component 6 is connected to the docking pipe 12, and the end of the docking pipe 12 is provided with a pushing mechanism 5. The pushing mechanism 5 stores liquid culture medium inside and is used to convey the liquid culture medium inside to the inside of the mixing component 6. The mixing component 6 is used to sample and process animal body fluids. The pushing mechanism 5 delivers the liquid culture medium into the mixing component 6 and mixes it with the body fluid sample. The delivery pipe 4 delivers the mixed sample inside the mixing component 6 into the culture unit 3.
[0023] Specifically, when using this veterinary testing microbial sampling and culture device, liquid culture medium is injected into the push mechanism 5 through the one-way valve 8 at the top of the push mechanism 5. Then, the mixing component 6 is manually pressed onto the sampling area on the animal's body surface. By rotating the knob 22 in the mixing component 6, the sampling cotton 25 on the inner side can be controlled to perform adhesion sampling on the sampling area on the animal's body surface. Then, the push mechanism 5 is controlled to transport the culture medium into the mixing component 6, which washes and mixes the surface of the sampling cotton 25. Finally, the culture medium liquid mixed with the sample is transported along the delivery pipe 4 to the culture unit 3 for static culture. During the culture process, by controlling the culture unit 3 to move horizontally inside the culture tank 2, the process of replenishing the culture medium nutrient solution, sealing, or changing the air environment can be achieved.
[0024] In this embodiment, the pushing mechanism 5 includes: The medium injection tube 7, the one-way valve 8, and the push rod 9 are provided. The inside of the medium injection tube 7 is used to store liquid medium. The push rod 9 is inserted into the end of the medium injection tube 7. The end of the push rod 9 is connected to a piston plate, and the piston plate is embedded in the inside of the medium injection tube 7. The one-way valve 8 is provided at the top of the medium injection tube 7.
[0025] The push mechanism 5 also includes: The extension plate 10 and the bonding plate 11 are integrally formed on the side of the culture medium injection tube 7, and the bonding plate 11 is integrally formed at the end of the extension plate 10. The bonding plate 11 is used to press on the sampling area, and the one-way valve 8 is used to add additional liquid culture medium towards the inside of the culture medium injection tube 7. The end of the culture medium injection tube 7 is connected to the docking pipe 12, and the docking pipe 12 is in communication with the interior of the culture medium injection tube 7. The push rod 9, in conjunction with the piston plate at the end, is used to push the liquid culture medium inside the culture medium injection tube 7 toward the interior of the docking pipe 12.
[0026] Specifically, by connecting the external liquid culture medium pipeline to the one-way valve 8, the liquid culture medium can be delivered into the culture medium injection tube 7. After stopping the injection, the culture medium inside the culture medium injection tube 7 can be pushed towards the mixing component 6 by pushing the push rod 9. During sampling, the rear bonding plate 11 is pressed onto the sample area of the animal body surface to be collected. The extension plate 10 area is held by the fingers, and the back of the hand is used to press against one side of the bonding plate 11. The pushing process of the push rod 9 can be completed with one hand, so that the other hand can directly control the mixing component 6 and drive the sampling component 15 to move.
[0027] In this embodiment, the hybrid component 6 includes: The mixture includes a hybrid interlayer 13, a moving channel 14, a pressing sleeve 16, and an adhesive plate 17. The moving channel 14 is integrally formed in the middle of the hybrid interlayer 13, and the pressing sleeve 16 is integrally formed at the end of the moving channel 14. The adhesive plate 17 is attached to the end of the pressing sleeve 16. The adhesive plate 17 is used to seal the inside of the pressing sleeve 16, and the pressing sleeve 16 is used to press against the area to be sampled.
[0028] The hybrid component 6 also includes: Sampling component 15, which includes: lead screw 21, knob 22, top spring 23, connecting post 24 and sampling cotton 25; A knob 22 is integrally formed at the end of the lead screw 21. A top spring 23 is welded to the end of the lead screw 21. A connecting post 24 is installed at the end of the top spring 23. Sampling cotton 25 is attached to the side and end of the connecting post 24. The connecting post 24 and the sampling cotton 25 are both cylindrical in shape. The lead screw 21 and the top spring 23 are both located in the internal area of the moving channel 14. The top spring 23 is used to press the connecting post 24 and the sampling cotton 25 into the sampling area.
[0029] The mixing component 6 also includes a partition plate 18, a plug hole 19 and a threaded sleeve 20. The lead screw 21 passes through the inside of the threaded sleeve 20, and the lead screw 21, in conjunction with the threaded sleeve 20, drives the end spring 23, the connecting post 24 and the sampling cotton 25 to rotate and translate. The lead screw 21 passes through the inside of the plug hole 19. Inside the mixing component 6, when animal body fluids are collected using the sampling component 15, after the sampling cotton 25 is mixed with the liquid culture medium, the sampling component 15 continues to move, which can directly squeeze the sampling cotton 25. This process can increase the amount of sample collected, and it does not require the sampling cotton 25 to be exposed to the outside, thus increasing the total amount of sample collected in a single sampling.
[0030] The edge of the partition 18 is integrally formed with the inner wall of the moving channel 14. The partition 18 is used to block and squeeze the end of the sampling cotton 25. After the partition 18 squeezes the end of the sampling cotton 25, it is used to discharge the body fluid sample adsorbed in the sampling cotton 25. The interior of the mixing interlayer 13 is in communication with the interior of the conveying pipe 4 and the interior of the docking pipe 12. The adhesive plate 17 is fixed to the outside of the pressing sleeve 16 by adhesive. The adhesive plate 17 is also used to block the sampling cotton 25. The diameter of the connecting post 24 is the same as the diameter of the insertion hole 19.
[0031] In use, simply place the top mixing component 6 against the surface of the animal to be sampled, then operate the sampling component 15 and push the pushing mechanism 5 to press the sampling cotton 25 onto the sampling area for sampling. The sample is then mixed with the flowing liquid culture medium and automatically transported to the end culture mechanism 3. Throughout the process, the sampling cotton 25 is always in a closed environment, reducing the probability of contamination of the sample by the external environment.
[0032] Specifically, by rotating the control knob 22, the lead screw 21 can be driven to rotate synchronously. The lead screw 21, in conjunction with the threaded sleeve 20, can move outward, thereby pulling the end spring 23 and the connecting post 24 to move outward. During sampling, the adhesive plate 17 at the end of the pressing sleeve 16 needs to be removed from the end of the pressing sleeve 16. At this time, the pressing sleeve 16 can be directly pressed against the area to be sampled. In this process, the blocking of the sampling cotton 25 by the adhesive plate 17 can be changed to the blocking of the sampling cotton 25 by the sampling area.
[0033] As the screw 21 moves outward after the knob 22 is turned, the top spring 23, initially in a compressed state, continues to push the connecting post 24 and the sampling cotton 25, ensuring that the sampling cotton 25 remains in contact with the sampling area. With the rotation of the screw 21, the top spring 23, connecting post 24, and sampling cotton 25 also rotate, allowing the sampling cotton 25 to fully contact the body fluid. Once the top spring 23 is completely relaxed, the screw 21 pulls the top spring 23 outward with the subsequent rotation of the knob 22, ultimately pulling the sampling cotton 25 into the middle area of the moving channel 14. Finally, the connecting post 24 passes through the insertion hole 19. At this point, the sampling cotton 25 is blocked by the partition 18 and compressed, squeezing out the body fluid adsorbed in the sampling cotton 25. During this process, it mixes with the injected culture medium and is transported along the delivery pipe 4 towards the culture mechanism 3.
[0034] In this embodiment, the front end of the culture tank 2 is provided with a sliding groove 29, the side of the flow guide chamber 27 is provided with a groove 38, both ends of the inner wall of the groove 38 are inserted with spring rods 42, and the end of each spring rod 42 is welded with a sealing block 41. The inner wall of the groove 38 is provided with a sample injection port 39.
[0035] One end of the culture tank 2 is provided with a diversion pipe 26, the interior of the diversion pipe 26 is connected to the interior of each flow guide chamber 27, the conveying pipe 4 is used to convey the sample into the interior of the flow guide chamber 27, and the flow guide chamber 27 is connected to the interior of the culture mechanism 3 through the sample injection port 39. The inner wall of the groove 38 is also provided with a vent 40. The other end of the culture tank 2 is provided with an end plate 30. The side of the end plate 30 is provided with a vent pipe 31. The vent pipe 31 is connected to the vent 40 through the interior of the flow guide chamber 27. Each groove 38 is provided with two sealing blocks 41. The sealing blocks 41 are used to seal the sample injection port 39 and the vent 40.
[0036] Specifically, the sample doped with culture medium enters the interior of the diversion pipe 26 through the delivery pipe 4, and then enters the guide chamber 27 through the diversion pipe 26. Finally, it flows into the culture mechanism 3 from the sample injection port 39 of the side groove 38 of the guide chamber 27. The bottom of the culture mechanism 3 passes through the interior of the gap 28, and with the help of the groove 38 and the slide 29, the culture mechanism 3 can slide directly along the culture tank 2.
[0037] During the sliding process, the culture mechanism 3 will move along the inside of the groove 38 and change the docking state between the culture mechanism 3 and the sample injection port 39 or the vent 40 inside the groove 38. When the culture mechanism 3 docks with the sample injection port 39, the culture medium and sample can be injected into the culture mechanism 3 through the pushing mechanism 5. At this time, the vent 40 is blocked by the nearby sealing block 41. When the culture mechanism 3 moves to the other end and finally docks with the vent 40, the nutrient solution or oxygen that needs to be replenished can be delivered to the culture mechanism 3 through the ventilation pipe 31. At this time, the sample injection port 39 is blocked by the nearby sealing block 41.
[0038] In this embodiment, the culture mechanism 3 includes: The petri dish 33, the observation cover 34, and the interface 35 are provided. The observation cover 34 is installed on the top of the petri dish 33. The top of the observation cover 34 is connected to the interface 35. The end of the interface 35 is used to be embedded in the interior of the groove 38. The diameter of the interface 35 is the same as the height of the groove 38. The interface 35 is used to communicate with the sample injection port 39 or the vent 40.
[0039] The cultivation facility 3 also includes: The base plate 32, the sliding plate 36, and the pull rod 37 are provided. The base plate 32 is disposed at the bottom of each culture dish 33. The bottom of the flow guide chamber 27 is provided with a gap 28. The base plate 32 passes through the inside of the gap 28. Each culture dish 33 is integrally connected by the base plate 32. The front end of the base plate 32 extends out from the inside of the slide groove 29. The front end of the base plate 32 is integrally formed with the sliding plate 36. The pull rod 37 is installed on the surface of the sliding plate 36.
[0040] In the bottom culture mechanism 3, multiple culture dishes 33 at the bottom can be controlled to move along the inside of the culture tank 2 at the same time, and the switching process of several states such as docking with the culture medium, culture sealing and oxygen delivery docking can be realized. The operation process is simple and convenient, and with the sealing block 41, the pollution caused by the external environment to the internal environment of the culture medium can be reduced during the switching process, thus improving the effectiveness of the final culture.
[0041] Specifically, by directly pulling the front lever 37, the bottom plate 32 can be moved horizontally by the sliding plate 36, ultimately moving each culture dish 33 along the culture tank 2. During this process, the top interface 35 can be connected to the sample injection port 39 or the vent 40 respectively. In the same process, the interface 35 can also push the sealing blocks 41 at both ends so that when the interface 35 is removed from the sample injection port 39 or the vent 40, the spring rod 42 can cooperate with the sealing block 41 to seal the sample injection port 39 or the vent 40.
