Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of microbial isolation and cultivation, and particularly to a microbial automatic isolation and cultivation device. Background Art
[0002] The cultivation step in pharmaceutical microbial detection and analysis is an important link to ensure the accuracy and reliability of the detection results. Usually, for a solution containing pharmaceutical microorganisms, direct filtration or centrifugal precipitation is used to complete the microbial separation, and then the separated microorganisms are placed on a culture medium suitable for microbial growth for cultivation. The prior art uses a more efficient centrifugal precipitation method in combination with a corresponding separation device to achieve rapid microbial separation.
[0003] For example, the Chinese patent with the application number CN202410330384.7 discloses a microbial separation device for pharmaceutical microbial inspection. The separation device body includes a centrifugal mechanism, a separation component, and a dialysis component. By installing multiple dialysis components at the edge of the centrifugal mechanism in an inclined state, the preliminary separation process of microbial precipitation and supernatant can be completed during centrifugation. Combining with the subsequent lifting movement control of the separation component, the purpose of rapid separation and efficient repeated separation can be achieved, making the microbial separation more thorough. However, in this separation device, after the microbial base liquid is centrifuged inside the centrifugal channel, the precipitated microorganisms accumulated on the surface of the dialysis component will flow back into the supernatant again in the state of stopping centrifugation, and the separation effect is not ideal. Moreover, after the microbial precipitate enters the collection bin through the annular docking port, the docking bin needs to be opened to take out the microbial precipitate. However, for anaerobic microorganisms, being exposed to the air environment during the separation and cultivation process will cause the death of microorganisms or the inhibition of their growth, resulting in limited application scope of this separation device.

[0076] In this embodiment, the feeding component includes:
[0077] A flow dividing seat 26, the flow dividing seat 26 is fixedly installed on the centrifugal disc 2, a centrifugal channel 27 is arranged inside the flow dividing seat 26, an interface 28 is arranged on the side end of the culture medium 6, and the interface 28 is communicated with the centrifugal channel 27;
[0078] The turning arm 29 has a material taking head 12 mounted thereon. The lower end of the turning arm 29 is hinged to the shunt base 26. The material taking head 12 is connected to the centrifugal channel 27 through the cavity structure of the turning arm 29. An inclined groove 30 is provided on the turning arm 29;
[0079] The sliding rod 31 is slidably arranged on the shunt base 26, and the lower end of the sliding rod 31 is connected to the lifting frame 18;
[0080] The sliding head 32 has its middle part mounted on the top end of the sliding rod 31, and both ends of the sliding head 32 are slidably arranged in the inclined groove 30;
[0081] The pressure pump 33 is mounted on the upper end of the shunt base 26, and the working end of the pressure pump 33 is connected to the centrifugal channel 27.
[0082] In this embodiment, during use, the storage cylinder 7 is driven by the second driving component to turn upwards so that its center line is in a vertical state, that is, the output end of the cylinder 17 drives the lifting frame 18 to lift upwards, drives the slider 21 to slide on the guide rod 23 through the support rod 20, and then pushes the precipitation bottom tank 8 to turn around the hinge point with the support table 22, so that the storage cylinder 7 on the precipitation bottom tank 8 turns synchronously. Then the connecting pipe 10 is connected to the circulation pipeline 5, and the microbial base liquid to be separated is added into each storage cylinder 7 through the circulation pump 4, the circulation pipeline 5 and the connecting pipe 10. Under the closing action of the opening and closing member, the microbial base liquid will not flow out of the precipitation bottom tank 8;
[0083] After an appropriate amount of the microbial base liquid enters, the connecting pipe 10 is controlled by the valve cover 9 to be closed, and then the storage cylinder 7 is driven by the second driving component to turn downwards. Through the reverse execution of the above operations, the center line of the storage cylinder 7 is in a horizontal state. During this process, the lifting frame 18 will also drive the sliding head 32 to slide in the inclined groove 30 through the sliding rod 31 to pull the turning arm 29 to turn, thereby driving the material taking head 12 to extend into the discharge opening 11;
[0084] Then the first driving component is started, and the driving motor 13 drives the driving wheel 15 to rotate. Through the driven wheel 16 and the rotating shaft meshed with the driving motor 13, the centrifugal disc 2 is driven to rotate centrifugally. After the centrifugal operation is completed, the driving motor 13 is shut down, so that the centrifugal disc 2 gradually stops rotating.

[0085] When detecting and analyzing anaerobic microorganisms, the solenoid valve on the material taking head 12 and the pressure pump 33 are simultaneously turned on. Under the negative pressure environment provided by the pressure pump 33, the air in the centrifugal channel 27 and the culture medium 6 is quickly extracted to form an anaerobic environment condition required by the microorganisms. The material taking head 12 sucks the precipitated microorganisms in the precipitation bottom tank 8, and enters the culture medium 6 through the cavity structure of the turning arm 29, the centrifugal channel 27 and the docking port 28. When detecting and analyzing aerobic microorganisms or insensitive microorganisms, the pressure pump 33 does not need to be turned on, and the precipitated microorganisms will flow by gravity along this flow path into the culture medium 6. The culture medium 6 contains coagulants such as agar, gelatin or carrageenan, etc. The microorganisms grow on the inner surface or inside of the culture medium 6 and finally grow into visible colonies to carry out operations such as microorganism detection analysis, identification and viable bacteria counting.
[0086] In this embodiment, as Figure 4 shown, the opening and closing member includes a reed 24 and a closing piece 25. The reed 24 is fixedly installed on the inner wall of the hemispherical bottom of the precipitation bottom tank 8, and the closing piece 25 is installed at the end of the reed 24. The closing piece 25 covers the discharge opening 11. When the material taking head 12 does not extend into the discharge opening 11, under the action of the self-elastic force of the reed 24, the closing piece 25 can completely block the discharge opening 11 to avoid liquid leakage.
[0087] In this embodiment, as Figure 3 、 Figure 6 shown, there are at least two turning arms 29. After the ends of the two turning arms 29 are turned close to each other, the material taking head 12 extends into the precipitation bottom tank 8 through the discharge opening 11, and the opening and closing member is in an open state, so that the material taking head 12 can completely suck the precipitated microorganisms in the precipitation bottom tank 8, avoiding the situation that the microorganisms on one side are insufficiently absorbed while the microorganisms on the other side accumulate.
[0088] In this embodiment, as Figure 3 、 Figure 4 、 Figure 5 shown, elastic clamping pieces 34 are provided at both ends of the precipitation bottom tank 8. The clamping ends of the elastic clamping pieces 34 cooperate with the outer end surface of the storage cylinder 7 to maintain the stability of the centrifugation process of the storage cylinder 7 and the precipitation bottom tank 8.
[0089] In this embodiment, as Figure 1 、 Figure 3 shown, a stabilizing portion for positioning the valve cover 9 is also installed on the fixed seat 19. The stabilizing portion includes:
[0090] A guide rod 35, the guide rod 35 is installed on the fixed seat 19;
[0091] A mounting block 36, the mounting block 36 is slidably arranged on the guide rod 35;
[0092] The spring 37 is sleeved on the guide rod 35. One end of the spring 37 abuts against the mounting block 36, and the other end of the spring 37 abuts against the fixed seat 19.
[0093] The clamping plate 38 is installed at the upper end of the mounting block 36. The edge end of the valve cover 9 is clamped on the clamping plate 38. During the centrifugation process, the valve cover 9 can remain stable on the clamping plate 38, avoiding the vibration of the storage cylinder 7 during the rotational centrifugation process, and ensuring that the position area of the precipitated microorganisms and the supernatant in the storage cylinder 7 is in a stable state.
[0094] In this embodiment, as Figure 1 , Figure 8 shown, a plurality of positioning blocks 39 are circumferentially installed on the inner wall of the top cover 3. Each of the plurality of positioning blocks 39 is provided with a positioning groove 40. The plurality of positioning grooves 40 are all matched with the outer side wall of the storage cylinder 7. The side end of the valve cover 9 is provided with an avoidance groove 41. The depth of the opening of the avoidance groove 41 is not less than the protruding length of the positioning groove 40. After the separation and cultivation operation is completed, a positive air pressure is provided to the microorganism flow path by the pressure pump 33 to automatically clean the flow path. Then, under the positioning of the positioning groove 40, the storage cylinder 7 is in a vertical state, the top cover 3 is opened, and the residual solution inside is sucked by the connecting pipe 10 to achieve the rapid cleaning of the entire separation and cultivation device.
