Description

Technical Field

[0001] The present invention relates to the technical field of microbial detection, and in particular to a microbial detection system and a detection method. Background Art

[0002] Microorganisms are widely involved in many fields such as food, medicine, industry and agriculture, environmental protection, sports, etc. Microbiological detectors are devices used in the sampling and research of air microorganisms in medical and health, food, pharmaceutical, clean rooms and workshops, hospital operating rooms, sterile wards and other departments.

[0003] The existence and activity of organisms often need to be confirmed by observing their growth, metabolism or other physiological characteristics. In order to improve the accuracy and efficiency of the test, it is usually necessary to dilute the sample, add identification fluid and mix it thoroughly. The use of diluent is a common and necessary operation in the process of microbial detection. In the process of microbial detection, the addition and thorough mixing of diluent and identification fluid are key operations. The diluent helps to adjust the concentration and uniformity of the sample, while the identification fluid helps to confirm the type and activity of the microorganism through chemical reactions or other biological reactions.

[0004] During the microbial testing process, samples are usually placed on a specially designed testing table to prevent bacteria and other impurities on the testing table from interfering with the test results. To ensure the accuracy of the experiment, multiple tests are usually required, and the samples will be replaced or reprocessed after each test. Each time the microbial sample or solvent is changed, a diluent or identification liquid must be added to the container and mixed thoroughly. At this time, in order to ensure that the liquid is fully uniform, two methods are usually used for mixing: one is to mix by shaking after snapping the container together; the other is to manually stir the solution with a glass stirring rod. However, the above-mentioned treatments during testing have some limitations, and are prone to solvent leakage, and there is a risk of contaminating the microbial testing equipment.

The cooperation of the moving component with the bracket and the cover can effectively close and seal the top of the vessel to prevent the solution from splashing, thereby avoiding pollution of the equipment and the environment. During the solution mixing process, the rotating component accurately controls the rotation of the support platform, and drives the cover, film and vessel to rotate together through friction to avoid loosening or twisting of the film, thereby ensuring a stable sealing effect, while ensuring that the solution is evenly mixed, and improving the accuracy and consistency of the detection. The device adopts an automated control system, and the operator only needs to set the vessel and solution, and the remaining operations are automatically completed by the mechanical device, reducing manual intervention and misoperation, and reducing the influence of human factors on the test results. Before mixing the test solution, when the cover is buckled on the vessel, the sealing effect of the film not only prevents contamination, but also prevents the solution from splashing out and contaminating the bottom of the cover during subsequent testing. When the cover is reset upward after mixing, the solution on the bottom of the film that is contaminated by mixing can be scraped off by the edge of the vessel. This design avoids the problem of dripping of the solution remaining on the film when the cover and the film leave the vessel. The mechanism of automatically winding and releasing the film can provide clean sealing materials for the next test.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] refer to Figure 1-Figure 9 , a microbial detection system, comprising: Testing table 100; A testing frame 101 is disposed on the testing table 100, and a storage opening 102 for placing vessels is opened on the testing frame 101; A support 103 is disposed on the testing platform 100 , a cover 104 is disposed at the bottom of the support 103 , and two reels 105 are disposed on the support 103 ; A film 106 disposed between two reels 105 for covering the cover 104; A microbial detector 107 disposed between the cover 104 and the storage port 102; A support platform 108 is provided in the inspection frame 101, and a plurality of positioning rods 109 are provided on the top of the support platform 108; The moving part disposed between the detection frame 101 and the bracket 103 is used to move the bracket 103 up and down. The bracket 103 can rotate the reel 105 in the process of moving downward to a preset position and resetting upward to drive the film 106 to roll automatically; A positioning member disposed between the support platform 108 and the positioning rod 109, used to move the positioning rod 109 to position the vessel on the support platform 108 when the moving member moves the bracket 103 downward; The rotating component provided in the detection frame 101 is used to rotate the support platform 108 when the support 103 moves downward to a preset position, so that the detection platform 203 can change the angle and mix the solution before detection; In the process of the moving part resetting the support 103 and the cover 104 upward, the horizontal positions of the support platform 108 and the vessel remain stable. When the support 103 and the cover 104 move to the preset position, the support platform 108 and the vessel move upward with the support 103 and the cover 104 by a preset distance, so that the cover 104 and the vessel are slightly separated, so that the solution contaminated by mixing at the bottom of the film 106 is scraped off by the edge of the vessel; Wherein, the moving part can rotate the microorganism detector 107 when displacing the bracket 103 to avoid the cover 104; By setting up the detection rack 101, during the microbial detection process, the vessel containing the sample is placed in the storage port 102 of the detection rack 101, and the detection personnel can inject the identification solution or diluent into the vessel to pre-treat the solution. When in use, the position of the bracket 103 can be moved downward by the moving component to allow the cover 104 on it to move close to the vessel. The microbial detector 107 between the cover 104 and the vessel will automatically rotate to avoid the position of the cover 104 to ensure smooth detection operation. During this process, the positioning component can also move the position of the positioning rod 109. Multiple positioning rods 109 move toward the vessel to keep the vessel stably and accurately at the detection position, avoiding shaking or position displacement during operation. In addition, in order to maintain the cleanliness of the detection environment when mixing the solution, a reel 105 is set on the bracket 103, and a film 106 is set between the reels 105. When the cover 104 moves downward to a position close to the vessel, the film 106 is unfolded under the drive of the reel 105 and covers the top of the vessel. When the cover 104 is buckled on the vessel, the film 106 not only forms an effective seal on the top of the vessel to prevent contamination, but also prevents the solution from splashing out and contaminating the bottom of the cover 104 during subsequent testing. After the mixing and testing are completed, when the test vessel is replaced, the bracket 103 will be reset, and the reel 105 will retract the film 106 to prepare clean sealing materials for the next test, effectively improving the test efficiency and environmental cleanliness. Specifically, after the moving part moves the bracket 103 and the cover 104 downward to close the top of the vessel, the rotating part set at this time can work to rotate the support platform 108. Since the cover 104 seals the vessel through the film 106, there is a certain friction between the cover 104 and the vessel. Therefore, when the rotating part rotates the support platform 108, the vessel is stably positioned under the action of the positioning part to ensure that it will not shift. The vessel is positioned by the positioning part, and the vessel can be rotated by the positioning part when the support platform 108 rotates. The rotation of the vessel can make the cover 104, the film 106 and the scroll 105 rotate together through friction, so as to avoid the independent rotation of the vessel causing the film 106 to twist or loosen, thereby maintaining the stable sealing effect of the film 106. During the rotation of the vessel, the solution is evenly mixed, which helps to improve the accuracy and consistency of the detection.In addition, before the rotating part rotates the support platform 108, the support platform 108 can be displaced downward for a distance. The purpose of this arrangement is that after the rotating part rotates the support platform 108 and the vessel to a suitable number of cycles to allow the solution to be mixed, the horizontal positions of the support platform 108 and the vessel remain stable during the process of the moving part resetting the moving bracket 103 and the cover 104 upward. When the bracket 103 and the cover 104 are reset upward to a preset position, the support platform 108 and the vessel move upward with the bracket 103 and the cover 104 by a preset distance so that the cover 104 and the vessel are slightly separated. Since the reel 105 can rotate to release and reel up the film 106 during the process of the bracket 103 resetting upward, the solution contaminated on the bottom of the film 106 due to mixing can be scraped off by the edge of the vessel. Through this design, the problem of dripping of the solution remaining on the film 106 when the cover 104 and the film 106 leave the vessel is avoided. After the mixing is completed, when the bracket 103 and the cover 104 are reset upward by the moving parts, the microbial detector 107 can also be rotated and reset to the initial position, and the detection unit of the detector can correspond to the solution in the vessel, and the microbial detector 107 begins to analyze the solution in the vessel. The detector monitors and detects the microbial population in the solution in real time through precise sensors and sampling technology. The detector can detect the concentration, type and activity state of microorganisms, and provide reliable data for subsequent analysis. During the detection process, the microbial detector 107 will continue to monitor the changes in the solution to ensure the continuity and accuracy of the entire process. By setting up a precise microbial detector 107, an effective positioning device and a precise mixing and closing system, the present invention not only optimizes the detection process, but also significantly reduces the error and contamination risk in the operation. The operator does not need to intervene frequently, reducing the possibility of human operation errors and environmental pollution. In addition, the sealing function of the film 106 also effectively avoids the leakage and cross contamination of the solution, providing a cleaner detection environment for the laboratory.

[0021] As a further solution of the present invention, the moving part includes a traction rope a200 connected to the bottom of the bracket 103, a rotating shaft 201 is rotatably connected in the detection frame 101, the other end of the traction rope a200 is wound on the rotating shaft 201, a spring a202 is connected between the bracket 103 and the detection frame 101, a detection platform 203 is provided on the detection frame 101, a microorganism detector 107 is connected to the detection platform 203, a connecting shaft 204 is connected to the detection platform 203, the connecting shaft 204 is rotatably connected to the detection frame 101, a spring b205 is connected between the connecting shaft 204 and the detection frame 101, and a traction rope b206 is also connected to the bracket 103, one end of the traction rope b206 is wound on the connecting shaft 204; By setting the rotating shaft 201, one end of the traction rope a200 is fixedly connected to the bottom of the bracket 103, and the other end is wound on the rotating shaft 201. When the rotating shaft 201 rotates, the traction rope a200 can be driven to pull the bracket 103 to move downward, so that the cover 104 is close to and closes the top position of the vessel. At this time, the spring a202 provides an upward reset force, and the bracket 103 and the cover 104 can be automatically reset after the rotating shaft 201 is released, ensuring the stable contact and separation of the cover 104 and the vessel. In addition, a connecting shaft 204 is provided on the detection platform 203, and the connecting shaft 204 is connected to the detection work frame 101 by a spring b205. When the bracket 103 moves downward, the connecting shaft 204 can be pulled by the traction rope b206. The rotation of the connecting shaft 204 under force can allow the detection platform 203 and the microorganism detector 107 thereon to rotate to avoid the position of the cover 104 and prevent the cover 104 from interfering with the detection process. When the bracket 103 is reset, the connecting shaft 204 and the detection platform 203 are also restored to the initial position under the action of the spring b205, so that the detector is in a normal detection preparation state.

[0022] As a further solution of the present invention, the cover 104 is rotatably connected to the bracket 103, the two sides of the cover 104 are connected to the connecting frame 207, the reel 105 is rotatably connected to the connecting frame 207, a rack a208 is slidably connected in the connecting frame 207, the reel 105 is provided with a gear a209 meshing with the rack a208, a ratchet mechanism 210 is provided between the gear a209 and the reel 105, and a spring c211 is connected between the rack a208 and the connecting frame 207; By setting the spring c211, the spring c211 can support the position of the rack a208 and determine the initial position of the rack a208. When the bracket 103 and the cover 104 move downward to the detection frame 101, the bottom of the rack a208 contacts the detection frame 101. When the bracket 103 continues to move downward and the cover 104 is buckled on the vessel, the rack a208 can slide in the connecting frame 207 and the gear a209 can rotate. The setting of the ratchet mechanism 210 can determine the rotation direction of the reel 105 to ensure that the reel 105 can rotate when the bracket 103 is reset upward. The potential energy of the spring c211 is used to reset the rack a208, so that the gear a209 rotates in the opposite direction and the reel 105 rotates through the ratchet mechanism 210. One reel 105 rotates to release the film 106, and the other reel 105 rotates to rewind the film 106. The used film 106 can be rewound and replaced with a clean film 106 to prepare for the next sealing vessel. This design automatically replaces the film 106 in each test to avoid pollution accumulation and provide a clean sealing environment for each test, thereby improving the accuracy and cleanliness of the test and effectively reducing human intervention.

[0023] As a further solution of the present invention, the positioning component includes a connecting ring 300 rotatably connected to the detection frame 101, a connecting rod 301 is connected to the bottom of the connecting ring 300, a lead screw 302 is rotatably connected to the connecting rod 301, a top block 303 slidably connected to the connecting rod 301 is threadedly connected to the lead screw 302, a folding rod 304 is connected to the bottom of the connecting ring 300, a positioning rod 109 is slidably connected to the folding rod 304, a spring d305 is connected between the positioning rod 109 and the folding rod 304, a gear b306 is connected to the bottom of the lead screw 302, and a gear c307 meshing with the gear b306 is connected to the rotating shaft 201; By setting the gear c307, the gear c307 and the gear b306 are meshed with each other, and the rotation of the rotating shaft 201 drives the gear b306 to rotate synchronously, thereby driving the lead screw 302 to rotate. When the lead screw 302 rotates, the top block 303 moves along the thread direction of the lead screw 302. When the top block 303 moves upward, it can touch the position of the positioning rod 109, allowing the positioning rod 109 to move toward the vessel on the top of the supporting platform 108. After the positioning rod 109 contacts the vessel, the vessel is stably fixed at the detection position, which can provide a stable support force for the vessel during the detection process, prevent the vessel from shaking or position shifting, thereby ensuring the accuracy of the detection operation.

[0024] As a further solution of the present invention, a ring body 308 is rotatably connected in the gear b306, and the ring body 308 is fixedly connected to the screw 302. A plurality of grooves a309 are provided on the ring body 308, and a damping rod a310 is slidably connected in the groove a309. A spring e311 is connected between the damping rod a310 and the groove a309. A damping groove a312 adapted to the damping rod a310 is provided on the inner wall of the gear b306. The damping groove a312 is a semi-spherical groove. One end of the rod a310 is semi-spherical, a traction shaft 313 is provided on the outer wall of the rotating shaft 201, a plurality of grooves b314 are provided on the outer wall of the rotating shaft 201, a damping rod b315 is slidably connected in the groove b314, a spring f316 is connected between the damping rod b315 and the groove b314, a damping groove b317 adapted to the damping rod b315 is provided on the inner wall of the traction shaft 313, the damping groove b317 is a semi-spherical groove, and one end of the damping rod b315 is semi-spherical; By setting the matching structure of the damping groove a312 and the damping rod a310, the damping rod a310 always keeps close contact with the inner wall of the damping groove a312 under the action of the spring e311, providing moderate friction. When the gear b306 rotates, the ring body 308 drives the lead screw 302 to rotate. When the top block 303 moves to the limit position, the positioning of the vessel is completed. Since the shaft 201 continues to rotate to drive the bracket 103 to move downward through the traction rope a200, the existence of friction allows the transmission to idle when encountering too much resistance or reaching the limit position, and the shaft 201 can continue to rotate to perform the next task. The rotating shaft 201 and the traction shaft 313 are connected by the damping rod b315, the damping groove b317 and the spring f316. Similarly, while avoiding movement conflict, the rotating shaft 201 can continue to rotate to provide driving force for the next rotation of the supporting platform 108. During the whole process, through the friction and idling control of the damping structure, the rotation of the transmission parts and the movement of each part can be effectively coordinated in different steps, reducing direct conflict between components.

[0025] As a further solution of the present invention, the rotating component includes a limit rod 400 slidably connected to the detection frame 101, the top of the limit rod 400 extends to the top of the detection frame 101 and is connected to a pressure ring 401, the bottom of the connecting ring 300 is provided with a limit groove 402 adapted to the limit rod 400, a spring g403 is connected between the limit rod 400 and the detection frame 101, a pressure rod 404 is connected to the connecting frame 207, which vertically corresponds to the position of the pressure ring 401, and the support platform 108 is slidably connected to the connecting rod 301; By setting the limiting rod 400, the limiting rod 400 can cooperate with the limiting groove 402 at the bottom of the connecting ring 300 under the force of the spring g403, thereby limiting the position of the connecting ring 300, and preventing the connecting ring 300 from rotating freely without position restriction when the lead screw 302 is driven to rotate by the gear c307, gear b306, ring body 308 and other components in the early stage of the rotation of the rotating shaft 201, and failing to effectively position the vessel. When the rotating shaft 201 continues to rotate and the bracket 103 moves downward to the preset position, the pressure rod 404 on the connecting frame 207 will contact the pressure ring 401, and the pressure ring 401 acts to cause the limiting rod 400 to move downward, thereby releasing the limiting rod 400 from the limiting groove 402, and at this time, the position of the connecting ring 300 is no longer restricted. When the rotating shaft 201 continues to rotate, the connecting ring 300 is no longer restricted. After the lead screw 302 rotates to the limit number of turns, the potential energy of the spring e311 and the friction between the damping rod a310 and the damping groove a312 cause the connecting rod 301 to rotate with the gear c307. The connecting rod 301 rotates around the rotating shaft 201, and the supporting platform 108 also rotates accordingly, and finally the supporting platform 108, the connecting rod 301, the positioning rod 109 and the connecting ring 300 rotate synchronously, thereby ensuring that the vessel rotates with the supporting platform 108.

[0026] As a further solution of the present invention, the rotating component also includes a spring h405 connected between the connecting rod 301 and the supporting platform 108, a top contact ring 406 is connected to the bottom of the supporting platform 108, the top contact ring 406 includes a flat surface 407 and a slope surface 408, a gear d409 is also connected to the rotating shaft 201, a rack b410 meshing with the gear d409 is slidably connected in the detection frame 101, a translation rod 411 in contact with the slope surface 408 of the top contact ring 406 is connected to the rack b410, and a spring i412 is connected between the translation rod 411 and the detection frame 101; By setting a spring h405, the spring h405 is used to limit the position of the support platform 108. After the container is placed in the storage port 102, it is supported by the support platform 108. When the rotating shaft 201 rotates but has not yet pulled the bracket 103 down to the position of the pressure ring 401, the translation rod 411 can be moved through the gear d409 and the rack b410. In the early stage of the movement of the translation rod 411, the slope surface 408 of the top contact ring 406 can be squeezed to move the top contact ring 406 downward. At this time, the rotation of the rotating shaft 201 is rotated through the gear c307, the gear b306, and the lead screw 302, and the positioning rod 109 has not yet contacted the container. Therefore, the support platform 108 can drive the container to move downward under the influence of the top contact ring 406. This step realizes the above-mentioned rotation. Before rotating the support platform 108, the surface of the support platform 108 is moved downward. When the positioning rod 109 contacts the vessel, the translation rod 411 reaches the slope surface 408 of the top contact ring 406. At this time, the downward displacement of the support platform 108 is completed. Since the rotating shaft 201 needs to continue to rotate to rotate the support platform 108, for this reason, in the specific setting, the number of tooth blocks on the rack b410 can be appropriately adjusted to ensure that when the translation rod 411 moves to the extreme position, the gear d409 contacts the last tooth block on the rack b410, but the rack b410 is no longer displaced. When the subsequent rotating shaft 201 rotates in the opposite direction to release the traction rope a200 to reset the position of the bracket 103 upward, the spring i412 is in a potential energy state, which allows the rack b410 to mesh with the gear d409. In the early stage of the reset movement of the translation rod 411, the translation rod 411 will slide on the flat surface 407 on the top contact ring 406, while the current bracket 103 continues to move upward. The purpose of this setting is to allow the cover 104 to be slightly separated from the container so that the film 106 can be rolled up. To scrape off the solution thereon, when the translation rod 411 reaches the slope surface 408 of the top contact ring 406, the top contact ring 406 and the support platform 108 are acted upon by the force of the spring h405 to overcome the friction between the positioning rod 109 and the vessel, and move upward, allowing the vessel to move upward a certain distance following the cover 104, so as to ensure that the film 106 can be rolled up and replaced for a longer distance as much as possible before the cover 104 is completely separated from the vessel, so as to better scrape off the solution on the film 106 and prevent dripping. It is worth noting that the rack a208 is relatively long. After the cover 104 is completely separated from the vessel, the rack a208 is still in a retracted state, that is, after the cover 104 is completely separated from the vessel, when the bracket 103 is reset upward, the reel 105 can continue to rotate and replace the film 106 again to avoid the new film 106 contacting the vessel and being contaminated by the solution when scraping off the solution, affecting the next time the vessel is closed, ensuring the cleanliness of the film 106 when the vessel is closed next time, and preventing contamination.

[0027] As a further solution of the present invention, a motor 500 is connected to the testing platform 100, and a driving shaft of the motor 500 is connected to the rotating shaft 201; By providing the motor 500 , the motor 500 can provide driving force for the rotation of the rotating shaft 201 .

[0028] As a further solution of the present invention, an electric push rod 501 is provided on the detection platform 203, and the telescopic shaft of the electric push rod 501 is connected to the microorganism detector 107; By providing the electric push rod 501, its telescopic shaft is connected to the microorganism detector 107, so as to achieve accurate adjustment of the microorganism detector 107. The electric push rod 501 can control the position of the microorganism detector 107 according to the detection requirements.

[0029] A microbial detection method is applicable to any of the microbial detection systems described above, and the specific steps are as follows: Step 1: Place the container containing the sample in the storage port 102 of the testing rack 101 and receive it on the supporting platform 108. The testing personnel inject the identification solution or diluent into the container to pre-treat the solution. Step 2: The moving component moves the position of the support 103 downward so that the cover 104 on the support 103 is close to the vessel, and the microorganism detector 107 between the cover 104 and the vessel automatically rotates to avoid the position of the cover 104; Step 3: When the positioning component moves the bracket 103 downward, the positioning component moves the plurality of positioning rods 109 toward the vessel, so that the vessel is stably and accurately kept at the detection position; Step 4: When the cover 104 moves downward to a position close to the container, the film 106 covers the top of the container. After the cover 104 is buckled, the film 106 seals the top of the container; Step 5: When the support 103 and the cover 104 move downward to the preset position, the rotating component rotates the support platform 108, and the support platform 108 rotates the container through the positioning component. The container rotates the cover 104, the reel 105 and the film 106 together through the friction between the film 106 and the cover 104; Step 6: After the mixing is completed, the moving part resets the support 103 and the cover 104 upward, and the solution contaminated by the mixing on the bottom of the film 106 is scraped off by the edge of the vessel; Step 7: The support 103 is driven by the moving component to return to the initial position, and the microorganism detector 107 rotates and returns to the corresponding container, and the microorganism detector 107 detects the solution in the container.
