Description

A microbial culture device Technical Field

[0001] This utility model relates to the field of microbial culture, and in particular to a microbial culture device. Background Technology

[0002] Vaccines are immunogenic preparations made from pathogenic microorganisms (such as bacteria, fungi, and viruses) or their metabolites through artificial attenuation, inactivation, or genetic engineering. These preparations stimulate the body to produce an immune response, thereby preventing disease. The bacterial / fungal strains or viral strains used to prepare vaccines (collectively referred to as bacterial / viral strains) must be protected from external contamination during cultivation, and microbial contamination of the external environment must also be avoided. Therefore, cultivation requires a relatively isolated environment. However, current isolation chambers for culturing microbial strains only consider isolation between the chamber itself and the external environment, neglecting isolation between different microorganisms within the same chamber. Therefore, when multiple different microbial strains are cultured simultaneously in the same chamber, cross-contamination may occur, affecting the purity of the target strain. Summary of the Invention

[0003] The purpose of this invention is to design a microbial culture device to solve the above problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A microbial culture device, comprising:

[0006] Incubator; The incubator is equipped with multiple placement positions and multiple partition positions. Each partition position is located between two adjacent placement positions. The incubator is hinged with a door for opening and closing.

[0007] Multiple culture plates; each culture plate is equipped with multiple culture positions, and a microbial culture container is fixedly installed in one culture position;

[0008] Multiple mounting brackets; one mounting bracket is used to mount one culture plate in one placement position;

[0009] Multiple partition panels; one partition panel can be detachably installed on one partition position. When the partition panel is installed on the partition position, two independent culture chambers are formed on both sides of the partition panel. Each culture chamber is equipped with an air inlet and an air outlet.

[0010] The beneficial effects of this invention are as follows: By dividing the incubator into multiple independent culture chambers using partitions, different microbial strains can be placed in different culture chambers for cultivation. At this time, the air inlet and outlet of each independent culture chamber are connected to different air sources, effectively avoiding cross-contamination between different microorganisms, ensuring the purity of the target microorganism culture, and realizing the simultaneous cultivation of multiple microorganisms, thereby improving the space utilization and work efficiency of the incubator. In addition, according to the actual situation, some or all partitions in the incubator can be temporarily removed to achieve changes in the space and size of different culture chambers, adapting to different cultivation needs and broadening the application range of the incubator.

[0023] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] As shown in Figures 1, 2, 3, and 4, a microbial culture device includes:

[0025] Incubator 1; Incubator 1 is provided with multiple placement positions 2 and multiple partition positions 3. One partition position 3 is located between two adjacent placement positions 2. Incubator 1 is hinged to a door 4.

[0026] Multiple culture plates 16; each culture plate 16 is provided with multiple culture positions 5, and one culture position 5 is used to fix and install a microbial culture container 6.

[0027] Multiple mounting pieces; one mounting piece is used to mount a culture plate 16 in a placement position 2;

[0028] Multiple partition panels 7; one partition panel 7 can be detachably installed on a partition position 3. When the partition panel 7 is installed on the partition position 3, two independent culture chambers 8 are formed on both sides of the partition panel 7. Each culture chamber 8 is provided with an air inlet and an air outlet.

[0029] The incubator 1 is divided into multiple independent culture chambers 8 by partitions 7, allowing different microorganisms to be placed in different culture chambers 8 for cultivation. At this time, the air inlet and outlet of each independent culture chamber 8 are connected to different air sources, effectively avoiding cross-contamination between different microorganisms and ensuring the purity of the target bacterial strains. At the same time, depending on the actual situation, some or all of the partitions 7 in the incubator 1 can be removed to achieve changes in the size of different culture chambers 8, adapting to different cultivation needs and broadening the application range of the incubator 1.

[0030] Sealing ring gaskets 9 are fixedly installed on both sides of the partition plate 7, and partition rings 10 are provided on both sides of the partition position 3. When the partition plate 7 is installed on the partition position 3, the two sealing ring gaskets 9 are pressed and contacted with the first side surface 11 of the two partition rings 10 respectively.

[0031] One of the partition rings 10 has a guide surface 12 on its first side 11. The distance between the first end of the guide surface 12 and the central axis of the incubator 1 is the first distance, and the distance between the second end of the guide surface 12 and the central axis of the incubator 1 is the second distance. The first distance is greater than the second distance. The end of the guide surface 12 that contacts the first side 11 is the first end of the guide surface 12, and the other end is the second end of the guide surface 12. The function of the guide surface is that the distance between the two sides of the two partition rings without guide surfaces can be slightly greater than the height of the partition plate, which facilitates the installation of the partition plate. The guide surface guides the partition plate, so that the sealing ring gasket 9 on the side of the partition plate away from the guide surface 12 is squeezed against the first side 11.

[0032] When installing the partition plate 7, the switch door 4 is opened, and the partition plate 7 is inserted between the two partition rings 10. When the first end of the partition plate 7 moves to the position of the guide surface 12, the partition plate 7 enters the partition ring 10 with the guide surface 12. When the switch door 4 is closed, the partition ring 10 located at the position of the switch door 4 also exerts a squeezing effect on the partition plate 7, increasing the squeezing force between the sealing ring gasket 9 on the side of the partition plate 7 away from the guide surface 12 and the first side surface 11, thereby achieving the purpose of dividing the two sides of the partition plate 7 into two independent culture chambers 8.

[0033] Each mounting component includes a mounting ring 13 and multiple suction cups 14. The mounting ring 13 is disposed on the inner side wall of the incubator to form a placement position 2. The handle of the suction cup 13 is connected to the mounting ring 13, and the suction disc end of the suction cup is connected to the culture plate 16, so that the culture plate 16 is fixedly mounted on the placement position 2.

[0034] Ventilation channels 15 are provided around the culture position 5 of the culture plate 16. The microbial culture container 6 is fixedly installed in the culture position 5 of the culture plate 16. The culture plate 16 is placed on the mounting ring 13 and the suction cup 14 is attached to the lower side of the culture plate 16 to achieve fixed installation of the culture plate 16. The ventilation channels 15 connect the space of the upper side and the lower side of the culture plate 16, and the gas in the culture chamber 8 flows from bottom to top to ensure contact with the microbial culture container 6 and achieve temperature control in the microbial culture container 6.

[0035] The microbial culture equipment also includes an oscillating motor 18, a shock-absorbing component, and a mounting base 19. The incubator 1 is mounted on the mounting base 19 via the shock-absorbing component, and the oscillating motor 18 is mounted on the base. The output end of the oscillating motor 18 acts on the incubator 1.

[0036] The shock absorption assembly includes at least three shock absorption springs 20, with both ends of the shock absorption springs 20 fixedly connected to the mounting base 19 and the lower end of the incubator 1, respectively.

[0037] The microbial culture equipment also includes at least one temperature control unit, each temperature control unit comprising:

[0038] Exhaust fan 21; The outlet of exhaust fan 21 is connected to the air inlet of culture chamber 8;

[0039] Temperature control chamber 22; Temperature control chamber 22 is filled with temperature control liquid;

[0040] Temperature control channel 23; the outlet of temperature control channel 23 is connected to the inlet of induced draft fan 21, the inlet of temperature control channel 23 is connected to the outlet of culture chamber 8, temperature control channel 23 is installed inside temperature control box 22, and temperature control liquid surrounds temperature control channel 23.

[0041] Water pump 24; the outlet of water pump 24 is connected to the inlet of temperature control box 22;

[0042] Heat exchanger 17; the inlet and outlet of one channel of heat exchanger 17 are connected to the outlet of temperature control box 22 and the inlet of water pump 24, respectively. According to the temperature control requirements, high temperature or low temperature gas or liquid is introduced into the other channel of heat exchanger 17.

[0043] The water pump 24 circulates the temperature-controlled liquid within the heat exchanger 17 and the temperature control chamber 22. The heat exchanger 17 heats or cools the temperature-controlled liquid according to the actual temperature control requirements. Then, the temperature-controlled liquid cools or heats the gas in the temperature control channel 23 accordingly. The induced draft fan 21 circulates the gas in the incubator 1 and the temperature control channel 23, ultimately controlling the temperature inside the incubation chamber 8. This equipment indirectly controls the temperature of the gas inside the incubation chamber 8 through the temperature-controlled liquid, avoiding localized high or low temperatures in the gas inside the incubation chamber 8. The accompanying drawings in the instruction manual show only one temperature control device to illustrate the principle; the temperature control devices connected to the other incubation chambers 8 are the same as those shown.

[0044] It should be noted that the air inlet, air outlet and corresponding gas involved in the temperature control are used to maintain the temperature inside the culture device. To avoid microorganisms being contaminated by external gases, internal circulation is chosen. The aforementioned gas is different from the gas required for microbial metabolism. The latter needs to enter and exit through other channels, which is a conventional design in this field and is not the focus of this utility model, so it will not be described in detail here.

[0045] The working principle of this microbial culture device is as follows:

[0046] When carrying out microbial culture, firstly, according to the actual needs of microbial culture, install the corresponding partition plate 7 to form one or more culture chambers 8 in the incubator 1. The uppermost outlet of each culture chamber 8 is connected to the inlet of a temperature control channel 23, and the lowermost inlet of each culture chamber 8 is connected to the outlet of a temperature control channel 23. The other inlets and outlets are closed. Then, microbial strains are placed in the culture chamber 8, and the corresponding culture can be carried out.

[0047] The technical solution of this utility model is not limited to the specific embodiments described above. All technical modifications made based on the technical solution of this utility model shall fall within the protection scope of this utility model.
