Description

Technical Field

[0001] The invention belongs to the technical field of microbial culture, and in particular relates to a Brucella culture device. Background Art

[0002] Brucella culture is one of the important means of diagnosing brucellosis (brucellosis). Brucella culture is mainly carried out by bacterial culture of blood, bone marrow and other specimens of suspected patients to isolate and identify Brucella. This culture method is of great significance for the clear diagnosis of brucellosis.

[0003] When culturing Brucella, it is usually recommended to collect 2 sets of blood culture bottles for culturing. The best time to collect blood is when chills or fever first occur, and it should be done before the use of antibiotics. This is because antibiotics may affect the growth of bacteria, thereby affecting the culture results.

[0004] During the culture process, the culture bottle needs to be placed in a 37°C insulation device and observed after three days. If no bacterial growth is seen, observe it every other day. If there are suspicious colonies, use an inoculation loop to inoculate them onto a Brucella agar plate (or blood plate) and continue culturing for further identification.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] The embodiment of the present invention provides a Brucella culture device, such as Figure 1-15As shown, the Brucella culture device comprises: a microorganism culture box 1 and a box cover 2, the top of the microorganism culture box 1 is open, and the box cover 2 is detachably mounted on the top of the microorganism culture box 1 by means of fixed ears 3, and is used to close the top opening of the microorganism culture box 1; a support plate 4, the support plate 4 is fixedly mounted in the microorganism culture box 1, and a plurality of bottle seats 5 are rotatably mounted on the support plate 4, all of which are used to place culture bottles 6, so that the culture bottles 6 can rotate to receive light heating, and the plurality of bottle seats 5 are distributed in multiple rows; a plurality of rectangular lifting guide grooves 7 are provided on the inner walls on both sides of the opposite sides of the microorganism culture box 1, and the rectangular lifting guide grooves 7 are arranged in groups, and the opening positions of the rectangular lifting guide grooves 7 are located in the gaps between the adjacent rows of the multiple rows of bottle seats 5, so that the grouped rectangular lifting guide grooves 7 and the multiple rows of bottle seats 5 are staggered; multiple groups of the Rectangular lifting strips 8 are slidably installed in the rectangular lifting guide grooves 7, and multiple rectangular lifting strips 8 are located above the support plate 4 and are staggered with the multiple rows of culture bottles 6 placed thereon; multiple rectangular lifting strips 8 are fixedly installed with lighting strips 9 on one side of the culture bottles 6, so that the lighting strips 9 can heat the rotating culture bottles 6 with light after being powered on; multiple rectangular lifting strips 8 are vertically threaded with lifting screws 10 to drive the corresponding rectangular lifting strips 8 to rise and fall, and the bottom ends of multiple lifting screws 10 are rotatably connected to the support plate 4, and the bottom ends of multiple lifting screws 10 extend to the outside of the bottom of the support plate 4, and multiple lifting screws 10 rotate synchronously with multiple bottle seats 5, and multiple lifting screws 10 rotate reciprocatingly to drive the rectangular lifting strips 8 and the lighting strips 9 to rise and fall reciprocally.

[0038] In this embodiment, when in use, the box cover 2 is first detachably mounted on the top of the microorganism culture box 1 through the fixing ear 3 to close the microorganism culture box 1. Subsequently, the culture bottle 6 containing the Brucella sample is placed on each rotating bottle holder 5. After starting the device, the bottle holder 5 starts to rotate, driving the culture bottle 6 to rotate so as to evenly receive the light heating. At the same time, by rotating the lifting screw 10 (these lifting screws 10 rotate synchronously with the bottle holder 5), the rectangular lifting strip 8 and the lighting strip 9 thereon can be driven to reciprocate and lift. The lighting strip 9 heats the rotating culture bottle 6 with light in the power-on state, and the lifting movement of the rectangular lifting strip 8 ensures that the light can be more evenly irradiated to different parts of the culture bottle 6. By adjusting the rotation speed of the lifting screw 10, the lifting frequency of the lighting strip 9 and the rotation speed of the culture bottle 6 can be controlled, thereby optimizing the heating effect.

[0039] The brucella culture device described in this solution realizes uniform light heating of the culture bottle 6 by designing the rotating bottle holder 5 and the reciprocating lighting light bar 9. This design not only improves the heating efficiency, but also ensures that the brucella sample in the culture bottle 6 can be evenly heated, which is conducive to its growth and reproduction.

[0040] In addition, the brucella culture device described in this solution also has the characteristics of simple structure and convenient operation. The design of the rectangular lifting guide groove 7 and the rectangular lifting strip plate 8 makes the lifting movement of the lighting light bar 9 stable and reliable, and the synchronous rotation of the lifting screw 10 and the bottle seat 5 ensures the coordinated operation of the entire device.

[0041] In a further preferred embodiment of the present invention, two temperature sensors 11 are fixedly installed on the microbial incubator 1, and the two temperature sensors 11 are respectively located above and below the microbial incubator 1, and the sensing ends of the two temperature sensors 11 are both located inside the microbial incubator 1, for monitoring the temperature at different heights inside the microbial incubator 1.

[0042] In this embodiment, two temperature sensors 11 are fixedly installed on the microorganism incubator 1. The two temperature sensors 11 are respectively located above and below the microorganism incubator 1, and their sensing ends are deep inside the microorganism incubator 1. When the device is running, the two temperature sensors 11 will monitor the temperature at different heights in the microorganism incubator 1 in real time and feed the data back to the control system. The control system can automatically adjust the power of the lighting strip 9 and the rotation speed of the lifting screw 10 according to the received temperature data, so as to achieve precise control of the temperature in the microorganism incubator 1. The operator can understand the temperature condition in the incubator at any time by observing the temperature display on the control system, and make manual adjustments as needed.

[0043] By installing two temperature sensors 11, this solution can monitor the temperature at different heights in the microbial incubator 1 in real time, ensuring that the temperature distribution in the entire microbial incubator 1 is more uniform. This design not only improves the accuracy of temperature control, but also helps to optimize the growth environment of Brucella and improve the culture efficiency. At the same time, the real-time monitoring function of the temperature sensor 11 also enables the operator to grasp the temperature condition in the incubator at any time, so as to make adjustments in time, avoiding the adverse effects on the culture effect caused by temperature fluctuations.

[0044] In a further preferred embodiment of the present invention, a heat dissipation pipe 12 is installed on either side of the microorganism culture box 1 , a valve is provided on the heat dissipation pipe 12 , and the heat dissipation pipe 12 is communicated with the inner cavity of the microorganism culture box 1 .

[0045] In this embodiment, a heat dissipation pipe 12 is added on either side of the microorganism incubator 1, and the heat dissipation pipe 12 is connected to the inner cavity of the microorganism incubator 1. When the temperature in the microorganism incubator 1 is too high, the operator can open the valve on the heat dissipation pipe 12 to discharge the hot air in the microorganism incubator 1 through the heat dissipation pipe 12, thereby reducing the temperature in the microorganism incubator 1.

[0046] In a further preferred embodiment of the present invention, a rubber pad 13 is fixedly installed in each of the plurality of bottle seats 5 to protect the culture bottles 6 when they are placed and to increase friction after they are placed.

[0047] In this embodiment, in order to improve the stability and safety of the culture bottle 6 in the bottle holder 5, a rubber pad 13 is fixedly installed in each of the plurality of bottle holders 5. When the culture bottle 6 needs to be placed in the bottle holder 5, the culture bottle 6 only needs to be gently placed on the rubber pad 13. The material of the rubber pad 13 is soft and has a certain elasticity, which can effectively prevent the culture bottle 6 from being damaged. At the same time, the surface of the rubber pad 13 also has a certain degree of roughness, which can increase the friction between the culture bottle 6 and the bottle holder 5, and prevent the culture bottle 6 from sliding due to vibration or shaking during the culture process.

[0048] In a further preferred embodiment of the present invention, a synchronous belt drive mechanism is provided at the bottom of the microbial incubator 1 for driving the plurality of bottle seats 5 to rotate synchronously, the synchronous belt drive mechanism comprising a plurality of rotating spindles 14 rotatably mounted at the bottom of the microbial incubator 1, the top ends of the plurality of rotating spindles 14 being respectively fixedly connected to the bottoms of the corresponding bottle seats 5, the bottom ends of the plurality of rotating spindles 14 being fixedly mounted with pulleys 15, a plurality of tensioning shafts 16 being mounted at the bottom of the microbial incubator 1, the plurality of rotating spindles 14, pulleys 15 and tensioning shafts 16 being divided into a plurality of groups according to the distribution of the bottle seats 5, a same synchronous belt 17 being sleeved on the plurality of pulleys 15 and tensioning shafts 16 in the same group, a pulley 18 coaxial with the rotating spindle 14 being mounted on the pulley 15, and the two pulleys 18 in two adjacent groups being driven by a synchronous belt 19 sleeve.

[0049] In this embodiment, a synchronous belt drive mechanism is provided at the bottom of the microbial incubator 1, aiming to realize the synchronous rotation of multiple bottle holders 5. The core components of the synchronous belt drive mechanism include multiple rotating spindles 14, which are rotatably mounted at the bottom of the microbial incubator 1, and the top ends are fixedly connected to the bottoms of the corresponding bottle holders 5. A pulley 15 is fixedly mounted at the bottom of the rotating spindle 14. In addition, a plurality of tensioning shafts 16 are also provided at the bottom of the microbial incubator 1 for adjusting the tension of a synchronous belt 17. According to the distribution of the bottle holders 5, the rotating spindles 14, the pulleys 15 and the tensioning shafts 16 are divided into multiple groups, and the pulleys 15 and the tensioning shafts 16 in each group are provided with the same synchronous belt 17.

[0050] In particular, a pulley 2 18 is additionally installed on the partial pulley 15, such as Figure 8As shown, when there are three groups of rotating main shaft 14 and belt pulley 1 15, at least one belt pulley 2 18 is installed on the two groups located on both sides, and at least two belt pulleys 2 18 are installed on the middle group, and the belt pulleys 2 18 of two adjacent groups are sleeved and driven by synchronous belt 2 19; or each group can be equipped with one belt pulley 2 18, and synchronous belt 2 19 can be installed so that it does not slip, that is, at least one belt pulley 2 18 is installed in each group of rotating main shaft 14. When the driving device is started, the rotating main shaft 14 will drive the belt pulley 1 15 and the belt pulley 2 18 to rotate, and then realize the synchronous rotation of all bottle seats 5 through the transmission of synchronous belt 1 17 and synchronous belt 2 19.

[0051] The design of the synchronous belt drive mechanism enables the microorganism incubator 1 to efficiently realize the synchronous rotation of multiple bottle holders 5, which greatly improves the uniformity and consistency of the culture and provides a more stable growth environment for the microorganisms.

[0052] In a further preferred embodiment of the present invention, a handle 20 is fixedly installed on the top of the box cover 2, a power protection shell 21 is fixedly installed on the bottom of the microorganism incubator 1, and the synchronous belt drive mechanism is located in the power protection shell 21.

[0053] In this embodiment, a handle 20 is added to the top of the box cover 2, and this design enables the operator to more easily carry and move the entire microorganism incubator 1. At the same time, a power protection shell 21 is fixedly installed at the bottom of the microorganism incubator 1, which completely wraps the synchronous belt drive mechanism, which not only plays a protective role, but also maintains the overall neatness.

[0054] During use, the operator only needs to move the microorganism incubator 1 to a suitable position using the handle 20 .

[0055] In a further preferred embodiment of the present invention, a base plate 22 is provided under the power protection shell 21, and multiple lifting sleeves 23 are fixedly installed at the bottom of the power protection shell 21. Lifting columns 24 are slidably installed in the multiple lifting sleeves 23, and the bottom ends of the multiple lifting columns 24 are fixedly connected to the top of the base plate 22. Positioning bolts 25 are threadedly installed on the multiple lifting sleeves 23 for resisting and positioning the height of the lifting sleeves 23.

[0056] In this embodiment, a base plate 22 is added below the power protection shell 21, and the height adjustment function is realized by the combination of multiple lifting sleeves 23 and lifting columns 24. During specific operation, the operator can rotate the positioning bolt 25 to make it rise or fall along the thread of the lifting sleeve 23, thereby contacting and fixing the height of the lifting sleeve 23. Since the bottom end of the lifting column 24 is fixedly connected to the base plate 22, the height of the entire microbial incubator 1 relative to the ground can be indirectly adjusted by adjusting the height of the lifting sleeve 23. This design enables the microbial incubator to adapt to laboratory tables or working environments of different heights, improving its practicality and flexibility.

[0057] In a further preferred embodiment of the present invention, a bottle placement groove is formed on the top of each of the plurality of bottle seats 5 for placing the culture bottles 6, and the rubber pad 13 is located on the bottom inner wall of the bottle placement groove.

[0058] In this embodiment, the tops of the multiple bottle holders 5 are designed with bottle placement grooves, which are specially designed for placing culture bottles 6. When microbial culture is required, the operator only needs to gently place the culture bottle 6 into the corresponding bottle placement groove. The rubber pad 13 is cleverly installed on the bottom inner wall of the bottle placement groove, which can not only provide soft support for the culture bottle 6, but also effectively prevent the culture bottle 6 from sliding or colliding during rotation or movement, thereby ensuring the stability and safety of the culture.

[0059] In a further preferred embodiment of the present invention, the position of the lamp beads of the lighting light bar 9 corresponds to the culture bottle 6, and the lamp beads are not arranged at positions other than the culture bottle 6.

[0060] In this embodiment, the position of the lamp beads can accurately correspond to the position of each culture bottle 6. Specifically, the lighting light bar 9 is cleverly installed in the microbial incubator 1, and the lamp beads thereon are accurately arranged at positions corresponding to the culture bottles 6, while no lamp beads are provided for areas where no culture bottles 6 are placed. Such a design ensures that light can directly irradiate each culture bottle 6, providing sufficient and uniform lighting conditions for the growth of microorganisms.

[0061] In a further preferred embodiment of the present invention, the outer sides of the microorganism culture box 1 and the box cover 2 are both coated with a heat preservation layer for enhancing heat preservation.

[0062] In this embodiment, according to the above content combined with this embodiment, the method and beneficial effects of the present claim are briefly described in accordance with the patent document, the corresponding names carry numbers, and the requirements are divided into three paragraphs.

[0063] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0064] In another embodiment of the present invention, the Brucella culture device also includes a reciprocating lifting drive mechanism for driving the multiple rotating spindles 14 to rotate synchronously and driving the multiple lifting screws 10 to reciprocate. The reciprocating lifting drive mechanism includes a driving motor 26 fixedly installed in the power protection shell 21, and a driving gear disc 27 is fixedly installed on the output shaft of the driving motor 26. A plurality of rotating spindles 14 corresponding to a row of the plurality of lifting screws 10 are fixedly sleeved with a driven gear 28, and the driven gear 28 corresponding to the driving gear disc 27 is meshed with it, and a plurality of The bottom end of the lifting screw 10 is fixedly installed with a reciprocating gear 29, and a plurality of track columns 30 and track rods 31 are fixedly installed in the microbial incubator 1. The track columns 30 and track rods 31 are arranged in groups and are all located below the support plate 4. The group of track columns 30 and track rods 31 are located between the adjacent rotating spindles 14 and the reciprocating gear 29. The group of track columns 30 and track rods 31 are slidably sleeved with the same rack plate 32, and the plurality of rack plates 32 are located on one side of the corresponding reciprocating gear 29 and are fixedly installed with a first tooth meshing therewith. The plurality of rack plates 32 and the rotating main shaft 14 are provided with positioning posts 35 fixedly connected to the inner wall of the bottom of the microorganism incubator 1. A plurality of the positioning posts 35 are provided with a rotatable sleeve 36. A plurality of the sleeves 36 are located on one side of the corresponding second tooth group 34 and are fixedly installed with a driving half gear 37 meshing therewith. A plurality of the sleeves 36 are fixedly installed with a swinging strip plate 38 on the other side of the plurality of sleeves 36. A plurality of the swinging strip plates 38 are provided with a track opening 39. The lower part of the plurality of the swinging strip plates 38 is provided with a track opening 39. Each of the power transmission shafts 40 is rotatably connected to the inner wall of the bottom of the microorganism culture box 1. The multiple power transmission shafts 40 are respectively located on one side of the corresponding rotating main shaft 14. The tops of the multiple power transmission shafts 40 are fixedly installed with disks 41. The tops of the multiple disks 41 are eccentrically fixedly installed with shift shafts 42. The multiple shift shafts 42 are respectively inserted into the corresponding track openings 39. The bottom ends of the multiple power transmission shafts 40 are fixedly installed with power transmission gears 43, and the multiple power transmission gears 43 are respectively meshed with the corresponding driven gears 28.

[0065] In this embodiment, the Brucella culture device is provided with a reciprocating lifting drive mechanism, which is driven by a driving motor 26 to realize the synchronous rotation of multiple rotating main shafts 14 and the reciprocating rotation of multiple lifting screws 10. Specifically, the output shaft of the driving motor 26 drives the driving toothed disc 27 to rotate, and the driven gear 28 meshing with the driving toothed disc 27 rotates accordingly, thereby driving the rotating main shaft 14 to rotate synchronously. At the same time, the reciprocating gear 29 at the bottom end of the lifting screw 10 is meshed with the first tooth group 33 on the rack plate 32. When the rack plate 32 slides on the track column 30 and the track rod 31, the reciprocating gear 29 and the lifting screw 10 will be driven to reciprocate. In addition, the second tooth group 34 on the rack plate 32 is meshed with the driving half gear 37 on the shaft sleeve 36, and the shaft sleeve 36 is fixedly connected to the inner wall of the bottom of the microorganism culture box 1 through the positioning column 35. When the driving half gear 37 rotates, the shaft sleeve 36 and the swinging strip plate 38 will be driven to swing. The track opening 39 on the swinging bar 38 cooperates with the dial shaft 42 on the disc 41, so that the power transmission shaft 40 rotates with the swinging of the swinging bar 38, and the power transmission gear 43 at the bottom end of the power transmission shaft 40 is meshed with the driven gear 28, thereby realizing the linkage between the rotating main shaft 14 and the lifting screw 10.

[0066] The reciprocating lifting drive mechanism realizes the synchronous driving of the rotating main shaft 14 and the lifting screw 10. At the same time, through the single driving source of the driving motor 26, the synchronous rotation of multiple rotating main shafts 14 and the reciprocating rotation of multiple lifting screws 10 can be realized, thereby improving the operation efficiency and stability of the device. In addition, the mechanism also realizes the linkage of rotation and lifting, so that Brucella can obtain more uniform light during the cultivation process, which is conducive to the growth and reproduction of microorganisms.

[0067] The coordination of the rack plate 32, the first tooth group 33, the second tooth group 34, the shaft sleeve 36, the driving half gear 37, the swinging strip plate 38 and other components in the reciprocating lifting drive mechanism realizes the transmission and linkage effect. Among them, the sliding of the rack plate 32 on the track column 30 and the track rod 31, and the swinging of the swinging strip plate 38 can realize the control of the rotating main shaft 14 and the lifting screw 10, so as to meet the culture conditions and experimental requirements.

[0068] In another embodiment of the present invention, a battery pack 44 is disposed in the power protection shell 21 , and the battery pack 44 is connected to the driving motor 26 , the lighting strip 9 and the temperature sensor 11 .

[0069] In this embodiment, a battery pack 44 is added inside the power protection shell 21. This design is intended to provide a continuous power supply to ensure that key components such as the drive motor 26, the lighting strip 9, and the temperature sensor 11 can operate normally. The battery pack 44 is connected to these components through wires to form a complete power supply system. When the Brucella culture device needs to be operated, the battery pack 44 will provide power to the drive motor 26; at the same time, it will also provide power to the lighting strip 9 to ensure that the lighting conditions in the incubator meet the needs of microbial growth; in addition, it will also provide power to the temperature sensor 11, so that it can monitor the temperature conditions in the microbial incubator 1 in real time.

[0070] In another embodiment of the present invention, the top ends of the plurality of lifting screws 10 are fixedly provided with downward pressure blades 45 for disturbing the internal hot air during rotation, and a transverse blade 46 is rotatably provided on the inner wall of one side of the microbial incubator 1, and a synchronous shaft 47 rotatably connected to the support plate 4 is provided below the transverse blade 46, and a bevel gear 48 is fixedly provided on the shafts of the synchronous shaft 47 and the transverse blade 46, and the two bevel gears 48 are meshed with each other, and a differential pulley 49 is fixedly provided on the bottom end of the synchronous shaft 47, and a differential belt pulley 50 is fixedly provided on a rotating main shaft 14 corresponding to the synchronous shaft 47, and the differential belt pulley 50 and the differential pulley 49 are provided with the same differential synchronous belt 51.

[0071] In this embodiment, the tops of the multiple lifting screws 10 of the Brucella culture device are all provided with downward pressure blades 45. When the lifting screw 10 rotates, the downward pressure blades 45 rotate accordingly, generating air flow disturbance, which helps to accelerate the flow of hot air inside the microbial culture box 1 and achieve uniform distribution of heat. At the same time, a transverse blade 46 is rotatably installed on the inner wall of one side of the microbial culture box 1, and the transverse blade 46 is linked with the synchronous shaft 47 through the transmission of the bevel gear 48. A differential pulley 49 is fixedly installed at the bottom end of the synchronous shaft 47, which is connected to a differential belt pulley 50 fixed on a rotating main shaft 14 through a differential synchronous belt 51. In this way, when the rotating main shaft 14 rotates, the differential belt pulley 50 will be driven to rotate, and then the differential synchronous belt 51 is driven to rotate the synchronous shaft 47 and the transverse blade 46, further enhancing the air circulation effect in the culture box.

[0072] The addition of the downward pressure blades 45 and the transverse blades 46 significantly improves the air circulation efficiency inside the Brucella culture device. The downward pressure blades 45 rotate with the lifting screw 10, effectively disturbing the internal hot air, avoiding the problem of local overheating or uneven temperature, and providing a more uniform growth environment for microorganisms. The rotation of the transverse blades 46 further accelerates the air flow in the incubator, helps to reduce the temperature gradient, and improves the accuracy of temperature control.

[0073] In another embodiment of the present invention, two return springs 52 are sleeved on the plurality of track posts 30 , and the two return springs 52 respectively abut against two sides of the corresponding rack plate 32 and against the inner walls of the microorganism incubator 1 on both sides.

[0074] In this embodiment, two return springs 52 are sleeved on each track column 30. The two return springs 52 are respectively located on both sides of the corresponding rack plate 32 and are in conflict with the inner walls of the microorganism incubator 1 on both sides. When the rack plate 32 slides on the track column 30, it will be affected by the elastic force of the return spring 52. This elastic force can help the rack plate 32 to quickly return to its original position after sliding and maintain its stability. At the same time, the presence of the return spring 52 can also reduce the friction and wear of the rack plate 32 during the sliding process and extend its service life.

[0075] In summary, compared with the related art, the present device realizes uniform light heating of the culture bottle 6 by designing the rotating bottle seat 5 and the reciprocating lighting light bar 9. This design not only improves the heating efficiency, but also ensures that the Brucella sample in the culture bottle 6 can be evenly heated, which is conducive to its growth and reproduction.
