Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical experimental equipment, in particular to a microorganism incubator. Background Art
[0002] With the continuous progress of society, the biomedical industry has also developed rapidly. A microorganism incubator is an important tool in biomedicine. It is a box used to cultivate microorganisms, which can assist people in medical research and help doctors better treat diseases.
[0003] When culturing microorganisms, their culture environment is particularly important. In the existing microorganism culture process, a sealed incubator is usually used. At the same time, in some laboratories, multiple culture dishes are used in one incubator for cost consideration, but there is a risk of cross - contamination. At the same time, certain gases will be generated during the breeding process of microorganisms. The accumulation of a large amount of gas will make the concentration of a single gas too high. For example, most aerobic bacteria will produce a large amount of carbon dioxide during respiration, which will reduce the oxygen content in the incubator, resulting in reduced activity or even death.
[0004] At the same time, most of the current incubators heat the inner side of the microorganism culture box directly through a heating rod to achieve temperature control. However, during the heating process of the heating rod, the heat is dissipated, so the temperature in the area around the heating rod will be relatively high, while the temperature in the area far from the heating rod is difficult to rise rapidly. Taking the temperature at the heating rod as the standard reference will make the temperature in other areas too low, affecting the cultivation efficiency and quality. Taking the area far from the heating rod as the temperature reference will make the temperature at the heating rod too high, affecting the survival rate of microorganisms.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] Refer to Figure 1 - Figure 2As shown in the figure, it includes an incubator 1, which is divided into several culture areas by a number of partition plates 5. There is a door 2 in front of the incubator 1, and a ventilation structure is provided at the rear of the incubator 1. The ventilation structure includes an electronically controlled air intake device and a passive exhaust device respectively connected to each culture area, and a heating device is provided in the electronically controlled air intake device.
[0028] See Figure 1 - Figure 5 As shown in the figure, the electronically controlled air intake device includes an equipment box 14 provided at the rear side of the incubator 1. A compressor 10 is provided in the equipment box 14. An atmospheric pressure gas tank 6 is provided on one side of the equipment box 14, and a high-pressure gas tank 12 is provided on the other side of the equipment box 14. A pressure gauge 13 is provided on the high-pressure gas tank 12. An atmospheric pressure intake pipe 7 is connected to the atmospheric pressure gas tank 6. A quick connector 8 for connecting to an external gas distribution device is provided at the top of the atmospheric pressure intake pipe 7. The atmospheric pressure gas tank 6 is connected to the suction end of the compressor 10 through an atmospheric pressure transmission pipe 9. The discharge end of the compressor 10 is connected to the high-pressure gas tank 12 through a high-pressure intake pipe 11. The high-pressure gas tank 12 is connected to a gas distribution block 16 provided in the equipment box 14 through a high-pressure transmission pipe 15. A number of air outlets are provided on the gas distribution block 16. Each air outlet is connected to an air exchange pipe 17. A number of air exchange pipes 17 penetrate through the equipment box 14 and the incubator 1 and are respectively connected to each culture area. An electromagnetic valve 18 is provided on each air exchange pipe 17.
[0029] As an optimized solution of the present utility model, by setting the quick connector 8, the atmospheric pressure intake pipe 7 can be quickly and conveniently connected to an external gas distribution device, so as to input the configured gas into the atmospheric pressure gas tank 6. Then, the compressor 10 can extract the configured gas through the atmospheric pressure transmission pipe 9 and send it into the high-pressure gas tank 12 through the high-pressure intake pipe 11. The high-pressure gas tank 12 sends the gas into the gas distribution block 16 and a number of air exchange pipes 17 through the high-pressure transmission pipe 15. The electromagnetic valve 18 is used to control each air exchange pipe 17 individually. When the electromagnetic valve 18 is opened, since the gas in the high-pressure gas tank 12 is under positive pressure, the gas can flow unidirectionally from the air exchange pipe 17 into the incubator 1 without reverse flow; at the same time, the pressure gauge 13 can facilitate the user to observe the air pressure and prevent air pressure imbalance caused by the failure of the compressor 10.
[0030] See Figure 1 - Figure 6 As shown in the figure, the passive exhaust device includes a number of branch exhaust pipes 19 connected to the rear side of the incubator 1. One end of each branch exhaust pipe 19 penetrates through the incubator 1 and is connected to the culture area. The other end of the branch exhaust pipe 19 is connected to the main exhaust pipe 21. The main exhaust pipe 21 is connected to an external purification device. A one-way valve 20 is provided on each branch exhaust pipe 19, and the flow direction in the one-way valve 20 is towards the direction away from the incubator 1.
[0031] As an optimized solution of the utility model, a branch exhaust pipe 19 is provided. When the air pressure in the culture area inside the cultivation box 1 rises, a pressure difference is generated on both sides of the one-way valve 20, and the one-way valve 20 is automatically opened. Thus, the gas in the culture area can flow outwards, flow from the main exhaust pipe 21 to the external purification equipment, and the gas will not flow back. Therefore, the exchange of gas between the culture areas can be prevented, resulting in cross-contamination.
[0032] Refer to Figure 1 - Figure 7 As shown, the heating device includes a heating rod 22 provided inside the high-pressure gas tank 12, and the heating rod 22 is an electrically controlled heating rod 22.
[0033] As an optimized solution of the utility model, by using the heating rod 22, the gas can be heated inside the high-pressure gas tank 12. During the gas transmission process of the compressor 10, the gas in the high-pressure gas tank 12 can be automatically stirred, so as to ensure the uniform temperature of the gas, and further ensure that the gas temperatures entering different culture areas are consistent.
[0034] Refer to Figure 1 - Figure 2 As shown, a transparent observation plate 3 is embedded in the door 2, a handle 4 is provided on the transparent observation plate 3, and sealing strips matching the transparent observation plate 3 are provided on the front sides of several partition plates 5; sealing rings are provided at the connection parts of several ventilation pipes 17 and the branch exhaust pipe 19 with the cultivation box 1.
[0035] As an optimized solution of the utility model, the setting of the transparent observation plate 3 facilitates the user to observe the state of the cultivated microorganisms, and multiple sealing strips and sealing rings ensure the sealing performance of the culture area and prevent gas leakage.
[0036] The usage process of the utility model:
[0037] First, install this cultivator, connect it to the circuit and the control circuit. At the same time, connect the quick connector 8 to the gas distribution device. The gas output by the gas distribution device is input into the normal-pressure gas tank 6, and then start the compressor 10 to compress the gas and send it into the high-pressure gas tank 12. Set the heating temperature of the heating rod 22 according to the cultivation requirements. The heating rod 22 can maintain the gas temperature in the high-pressure gas tank 12, and then the culture dish can be placed in the cultivator.
[0038] Then, slightly open the solenoid valve 18 on the ventilation pipe 17 corresponding to the culture area to be used. Due to the pressure difference, the gas in the high-pressure gas tank 12 will automatically flow into the culture area, causing the air pressure in the culture area to rise, thus opening the one-way valve 20 and discharging the gas in the culture area. By continuously circulating, the air composition and temperature in the cultivator can be kept consistent, and the microorganisms are always in the optimal cultivation environment. At the same time, the solenoid valve 18 corresponding to the culture area without the culture dish placed is closed, and no heating and exhaust are carried out in the culture area, reducing energy consumption.
[0039] It should be understood that the above specific embodiments of the present utility model are only for illustrative explanation or interpretation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
