Description
Technical Field
[0001] The present invention relates to the technical field of incubators, in particular to an incubator capable of adjusting the angle of a culture medium. Background Art
[0002] Microbial culture is an important technical means in the fields of biomedicine, food testing, environmental monitoring, etc. In the traditional microbial culture process, slant culture medium is widely used because of its advantages such as increasing the culture surface area and facilitating bacterial inoculation and observation. However, in the existing technology, the observation of bacterial growth in slant culture medium relies entirely on manual operation. The experimenter needs to take out the culture tubes one by one every day and observe whether there is bacterial growth with the naked eye or under a microscope. This process needs to be repeated until bacterial growth is observed or the longest negative growth cycle is reached. This traditional observation method is labor-intensive and has low observation efficiency. When testing large quantities of samples, the experimenter needs to repeat the monotonous operation of taking out the tubes, observing, and putting them back.
[0003] At the same time, existing incubators usually use fans or air circulation systems to maintain uniform distribution of CO2 concentration and temperature inside the incubator. Although this traditional air circulation method can improve environmental uniformity to a certain extent, it also brings significant side effects:
[0004] (1) Increased evaporation of the culture medium: The airflow generated by the fan forms forced convection on the surface of the culture dish, significantly accelerating the evaporation process of water in the culture medium. According to mass transfer theory, the evaporation rate under forced convection conditions is much higher than that under natural convection conditions. This accelerated evaporation not only affects the concentration stability of the culture medium, but may also change the proportion of nutrients in the culture medium;
[0005] (2) Uneven evaporation: The air velocity near the fan is higher, causing the evaporation rate of the culture medium in this area to be significantly higher than that in the area far from the fan, resulting in differences in the moisture content of the culture medium at different locations in the chamber. This uneven evaporation pattern will lead to inconsistency in the culture environment and affect the reproducibility of experimental results;
[0006] (3) Increased culture medium consumption: In order to maintain the appropriate liquid level and concentration of the culture medium, culture medium needs to be added frequently, which not only increases the experimental cost and operational complexity, but also may introduce contamination risks during the replenishment process.
[0007] Therefore, the existing technology lacks a comprehensive technical solution that can achieve uniform distribution of environmental parameters within the incubator, effectively control culture medium evaporation, and improve culture medium observation efficiency. Based on this, the present invention designs an incubator with adjustable culture medium angle to solve the above problems. Summary of the Invention
[0008] The object of the present invention is to provide an incubator with adjustable culture medium angle. The device adds a steering joint and a slide rail, and the steering joint and the slide rail are used to set up the culture rack. A test tube slot is provided on the side of the culture rack to clamp the test tubes. At the same time, the test tube slots are arranged in a straight line, and the culture rack can be slid out of the culture chamber at one time through the slide rail, so that personnel can directly observe the culture medium in the test tube slot from the side without having to take them out one by one for observation. Especially when a large number of samples are cultured at the same time, the device can greatly simplify the operation, and the culture rack can be pulled out to observe the bacterial growth of the inclined culture medium of the entire row of culture racks at one time, thereby improving work efficiency. Moreover, the device can adapt to a variety of inclined culture medium test tubes of different specifications by replacing the culture rack, and the inclination angle of the culture rack can be adjusted through the steering joint, thereby meeting the requirements of the growth environment for bacteria at different growth stages.

[0021] The culture chamber is divided into two layers, upper and lower, by a partition;
[0022] The partition is also provided with a plurality of slide rails in the front-to-back direction, and the slide rails are also rotatably mounted on the top of the partition through a steering joint;
[0023] The direction and structure of the slide rail on the partition are the same as those of the slide rail at the bottom of the culture chamber, and a culture rack is also installed on the top of the partition through the slide rail.
[0024] Furthermore, the culture rack has a plurality of replacement parts, and the test tube slots of the replacement parts of the culture rack have a plurality of different diameters;

[0043] See also Figures 1 to 8As shown, the present invention provides an incubator capable of adjusting the angle of the culture medium. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings in the specification and specific implementation methods.
[0044] In a specific embodiment of the technical solution of the present invention:
[0045] It includes a box body 1, a steering joint 2, a culture rack 3, and a flow guide device;
[0046] The box body 1 is a sealed shell, and the interior of the box body 1 is a hollow culture chamber 12. A sealed door 11 is provided on the front of the box body 1. The sealed door 11 is sealed to the front of the box body 1 by a hinge and can be easily opened. The edge of the sealed door 11 is provided with sealant. Its structure is the same as that of a refrigerator door, and it can remain sealed after closing.
[0047] The steering joint 2 is a universal ball joint, which can be a universal ball joint on the mobile phone holder. This design allows the connection between the connecting parts to be freely adjusted at different angles and directions, thereby meeting various support requirements. The universal ball joint design enables the holder to rotate 360 degrees.
[0048] Multiple slide rails 21 are arranged in the culture chamber 12 along the front-to-back direction. Multiple steering joints 2 are evenly arranged at the bottom of each slide rail 21. The steering joints 2 on a single slide rail 21 are arranged in a straight line along the front-to-back direction. The angle of the slide rail 21 locked on it can be adjusted by the steering joints, allowing the slide rail 21 to rotate left or right. The steering joints 2 do not touch each other, and the planes on which each steering joint 2 is located are parallel to each other.
[0049] Each slide rail 21 is rotated and locked in the culture chamber 12 through the steering joint 2;
[0050] Each adjacent slide rail 21 does not contact each other, each slide rail 21 is locked on the steering joint 2 along the front-to-back direction, and is vertically distributed front-to-back, and each slide rail 21 is parallel to each other.
[0051] Multiple steering joints 2 form a group. Multiple groups of steering joints 2 are provided at the bottom of the culture chamber 12 and the top of the partition 22. Each group of steering joints 2 is fixedly mounted on the bottom plane of the culture chamber 12 or the top of the partition 22 in the front-to-back direction. They are evenly distributed in a straight line in the front-to-back direction. Each slide rail 21 is mounted on the top of the same group of steering joints 2, so that the slide rail 21 can be adjusted and swung in the left and right directions.
[0052] The straight lines of each set of steering joints 2 are parallel to each other, that is, the front-rear axes of each slide rail 21 are ensured to be parallel to each other.
[0053] The culture rack 3 is mounted in the top chute 23 of the slide rail 21. After the sealed door 11 is opened, the culture rack 3 can slide forward along the chute 23 to the outside of the box 1, making it easier to check the culture medium.
[0054] A partition 22 is also horizontally arranged inside the culture chamber 12. The partition 22 is horizontally arranged at the middle height position of the culture chamber 12 along the front-to-back direction. The partition 22 is horizontally arranged on the horizontal central axis plane of the culture chamber 12. The culture chamber 12 is divided into two layers, upper and lower, by the partition 22; there are upper and lower culture racks 3 in the culture chamber 12, and the culture racks 3 are arranged in two layers, which is convenient for placing more inclined culture media and improving the efficiency of culturing strains.
[0055] A plurality of slide rails 21 are also provided on the partition 22 along the front-to-back direction, and the slide rails 21 are also rotatably mounted on the top of the partition 22 through the steering joint 2;
[0056] The slide rail 21 on the partition 22 has the same direction and structure as the slide rail 21 at the bottom of the culture chamber 12, and the culture rack 3 is also installed on the top of the partition 22 through the slide rail 21. Therefore, the slide rail 21 on the top of the partition 22 can also be adjusted to the left and right directions through the steering joint 2;
[0057] Each rail 21 is provided with a slot 23 with openings at the top and front. A culture rack 3 is slidably mounted in the slot 23 at the top of each rail 21 along the front-to-back direction. The culture rack 3 can slide out of the front opening of the slot 23. A smooth mating friction surface, such as a mating surface of a sliding bearing, can be provided in the slot 23 at the top of the rail 21, and the culture rack 3 and the slot 23 can be a transition fit. The front opening of the slot 23 at the top of each rail 21 is narrower, that is, the frontmost opening of the slot 23 is narrower and forms a transition fit with the rail 21, while the normal portion of the slot 23 forms a transition fit with the rail 21 and is provided with a smooth mating surface. In other words, the slot 23 needs to slide smoothly on the inside and narrower on the outside, making it more difficult for the culture rack 3 to slide out of the slot 23, but allowing smoother sliding inside.
[0058] The culture rack 3 of this device can slide on the chute 23 at the top of the slide rail 21. The front end of the chute 23 is open, and the culture rack 3 can also slide out from the front end opening of the chute 23 for replacement. The culture rack 3 also has different models to match the slant culture medium test tubes of different specifications.
[0059] The culture rack 3 is a vertical flat plate structure, and a plurality of test tube slots 31 are provided on a vertical side wall of one side of the culture rack 3. The plurality of test tube slots 31 are arranged in a straight line in the front-to-back direction. The culture rack 3 has a plurality of replacement parts, and the test tube slots 31 of the replacement parts of the culture rack 3 have a plurality of different specifications and diameters. The test tube slots 31 are vertically arranged U-shaped tube clamps, and the test tube slots 31 are open on the vertical side wall of the culture rack 3.
[0060] The culture rack 3 is tilted left or right by adjusting the slide rail 21 and the steering joint 2. The culture rack 3 is locked in the chute 23, tilting along with the slide rail 21. This in turn tilts the culture tubes within the culture rack 3, exposing the left side of the chute 31 for direct inspection of bacterial growth within the culture. In this device, the chute 31 opens on the left side, so the slide rail 21 adjusts the chute 21 to the right, facilitating direct inspection of bacterial growth on the inclined surface of the culture. Furthermore, the entire culture rack 3 is tilted, allowing the chute 23 to be directly withdrawn, facilitating direct inspection of the culture tubes from outside the incubator 1. This eliminates the need to remove each tube individually for inspection, significantly improving work efficiency.
[0061] The flow guide device includes a flow guide ball 4 and a flow guide rod 43. The flow guide ball 4 is a sphere, and the flow guide rod 43 is a cylinder. The flow guide rod 43 is provided at both the upper and lower ends of the flow guide ball 4. Two flow guide balls 4 and three flow guide rods 43 are vertically connected in series at intervals to form an integral structure. The axis of each flow guide ball 4 and each flow guide rod 43 coincides.
[0062] The outer wall of each guide ball 4 and each guide rod 43 is inwardly recessed to form a guide groove 41, which is a spiral groove;
[0063] A motor 42 is installed at the upper end of the flow guide device, and a bearing seat 44 is installed at the lower end of the flow guide device. The flow guide device is rotatably installed in the culture chamber 12 through the motor 42 and the bearing seat 44, and the rotation axis of the flow guide device is vertically arranged.
[0064] The interior of the housing 1 of the device does not require an air outlet, which is a characteristic of the device. If air were to be blown, significant airflow would be generated, which would cause the culture medium near the wind to dry out too quickly. The device does not blow air, but only stirs the air inside the culture chamber 12 through the flow guide device, so that the various gas components are evenly distributed within the culture chamber 12. However, no significant airflow is generated within the culture chamber 12.
[0065] The rotating outer wall of the guide device will disturb the interior of the culture chamber 12 to form a vortex guide. Through the speed difference and the different diameters of the guide ball 4 and the guide rod 43, the gas is disturbed and stirred, and the concave guide groove 41 on its surface will further disturb the airflow, causing the airflow to circulate along the inside of the culture chamber 12, but without forming an airflow, which is gentler and more stable, and at the same time can evenly blow the carbon dioxide into the culture chamber 12.
[0066] The box body 1 is an intelligent water-jacketed incubator. A controller 13 is provided on the outside of the box body 1. The motor 42 is connected to the controller 13. The motor 42 is provided inside the box body 1 and is not in the culture chamber 12. The rotation speed and direction of the motor 42 are controlled, and the temperature, humidity, carbon dioxide air inlet, exhaust port, humidity sensor, and temperature sensor are controlled to achieve constant temperature and humidity inside the box body 1. CO2 can also maintain a constant value, so that the environment in the culture chamber 12 remains constant. This structure is a commonly used structure of a water-jacketed incubator.
[0067] It should be noted that:
[0068] 1. In bacterial culture, slant culture media need to be observed daily for bacterial growth. The existing operation is to extract culture tubes one by one, observe, and then put them back into the test tube rack. The operation of one culture tube is not difficult, but when the number reaches a certain level, the entire observation process takes a lot of time. Every small step optimized can greatly reduce the number of repeated operations. The present device optimizes the operation of taking and placing culture tubes and simplifies the observation operation. The entire observation process only requires extracting the culture rack 3 and then pushing the culture rack 3 back, which greatly simplifies the entire observation process and effectively improves the inspection efficiency.
[0069] 2. This device can adjust the angle between the test tube and the culture medium inside it, allowing the culture medium to be adjusted to different angles at different stages of cultivation, which is impossible with existing equipment. This device can adjust different angles for cultivation at different stages, especially in the early stages of cultivation. The tilted state allows the inoculated bacteria to slowly flow and spread along the inclined surface of the culture medium under the action of gravity, which is conducive to the uniform distribution and growth of bacteria across the entire inclined surface of the culture medium, which cannot be achieved with vertically placed culture medium.
[0070] 3. Existing incubators use fans to mix the various gas components inside. This operation results in different degrees of dryness between culture tubes near and far from the fan, making it difficult to achieve a uniform bacterial growth environment. The flow guide device of this device, through the gourd-like structure of the flow guide ball 4 and the flow guide rod 43, uses the Magnus effect. Through the rotation of this flow guide device, the air can be stirred and the various gas components inside can be mixed evenly without blowing air into the culture chamber 12.
[0071] When the present invention is in use, bacteria are inoculated, and the inoculated culture medium test tubes are placed one by one in the test tube groove 31. Test tubes of the same batch and model are placed in the same culture rack 3, and strains of the same type are also placed on the same culture rack 3 as much as possible. Labels can be affixed to the test tubes for distinction, and the labels should not block the culture medium observation area of the test tubes.
[0072] In the early stage of culture medium strain inoculation, the culture medium needs to be tilted to be more conducive to its growth. The culture rack 3 with the culture medium test tube is placed in the slide groove 23 at the top of the slide rail 21, and then in the steering joint 2. The steering joint 2 is adjusted and the slide rail 21 is adjusted to be tilted to the left or right so that the culture medium is also tilted. The strain is cultured more closely and the culture medium is tilted at a certain angle as much as possible, generally 45°-60°. At this time, the bacteria are more likely to flow and diffuse on the inclined surface of the culture medium under the action of gravity.
[0073] After a period of cultivation, generally about a week, the culture rack 3 is adjusted, and the slide rail 21 and the steering joint 2 are adjusted so that the top plane of the slide rail 21 is adjusted to be horizontal, and the culture rack 3 is adjusted to be vertical, thereby adjusting the culture medium test tube to a vertical state and carrying out the next stage of cultivation.
[0074] When observing the slant culture medium, one only needs to pull out the entire culture rack 3 along the slide rail 21 and observe the culture medium inside the test tube from the opening of the test tube slot 31. No other operations are required, and the personnel can directly check the culture medium in the entire row of test tubes. After the inspection is completed, if it is necessary to operate a certain slant culture medium, the individual test tubes can be directly removed for operation. If no additional operation is required, the entire row of culture racks 3 can be pushed back into the culture chamber 12 along the slide rail 21.
[0075] After inoculation, the slant culture medium is kept tilted for a period of time, about 1 week; the main reasons for turning it upright are:
[0076] 1. Promote initial growth and spreading: The inclined state allows the inoculated bacteria to slowly flow and spread along the slope of the culture medium under the action of gravity, which is conducive to the uniform distribution and growth of bacteria on the entire slope of the culture medium.
[0077] 2. Prevent excessive moisture at the bottom of the culture medium: In the early stage of strain inoculation, the test tube is kept tilted to allow condensed water to flow down the slope and not soak into the culture medium, forming a shallower water layer, effectively avoiding excessive water accumulation at the bottom of the culture medium, preventing contamination and bacteria from being washed away by accumulated water.
[0078] 3. Optimize oxygen supply: The tilted state provides a larger gas-liquid contact area. When the test tube is placed vertically, the contact surface is only the inner diameter of the test tube. When it is placed tilted, the greater the tilt, the larger the gas-liquid contact area, which is more conducive to the initial growth of aerobic bacteria.
[0079] 4. Control the growth rate: After one week, the bacteria have grown stably, and turning to an upright state can slow down the growth rate, making it suitable for long-term storage.
[0080] 5. Extend the storage time: The bottom of the culture medium test tube is thicker in the upright state, and the moisture is retained longer, which can extend the shelf life of the strain and prevent the culture medium from drying out too quickly.
[0081] This method of placing the culture medium test tubes, which is first tilted and then upright, combines the advantages of two different placement states, which not only ensures the good growth of bacteria but also facilitates long-term preservation.
