Description

Technical Field

[0001] This invention relates to an incubator, and more particularly to a bacterial incubator for testing. Background Technology

[0002] In medical testing, bacterial culture is a fundamental and crucial step. It aims to artificially induce bacterial reproduction and multiplication under suitable growth environments and conditions. The cultured bacteria are then used for research, identification, and application. This technique is essential for determining the presence and types of pathogenic and opportunistic pathogens, providing important evidence for further diagnosis and treatment. As a specialized device providing constant temperature and humidity, the performance of a bacterial incubator directly affects the growth status of microorganisms and the accuracy of test results.

[0003] Modern incubators typically employ a one-piece cavity design, with multiple layers of partitions or supports fixed inside to hold culture tubes. However, in practical use, some shortcomings exist: due to the fixed internal space of the incubator, when there are many culture tubes, other tubes are easily bumped during handling, leading to sample contamination, tube breakage, etc.; because the tubes to be retrieved are located at the innermost part of the chamber, handling them is inconvenient, and the prolonged handling time can cause violent disturbance to the culture environment inside the incubator, affecting the bacterial culture results.

[0004] To address the above issues, we provide a bacterial incubator for testing. Summary of the Invention

[0045] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0046] This application provides a bacterial incubator for testing.

[0047] Example 1, as Figure 1-12 As shown.

[0048] A bacterial culture chamber for testing includes an outer box 1, wherein an intermediate plate 13 is installed in the middle of the inner cavity of the outer box 1, dividing the inner cavity of the outer box 1 into an upper cavity 11 and a lower cavity 12.

[0049] A bacterial culture chamber for testing includes an inner chamber 2. Several inner chambers 2 are detachably installed inside the upper cavity 11 and the lower cavity 12. Preferably, there are two inner chambers 2 inside the upper cavity 11 and the lower cavity 12.

[0050] Both the outer box 1 and the inner box 2 are composed of a box body and a box cover. One side of the box cover is rotatably connected to the front side wall of the box body. The box cover can be opened and closed, thereby controlling the opening and closing of the outer box 1 and the inner box 2.

[0051] By dividing the inner cavity of the outer chamber 1 of the incubator into upper and lower independent cavities, and combining this with a detachable inner chamber 2, modular partitioning of the culture space is achieved. Multiple inner chambers 2 can provide different culture environments. This facilitates the classified culture of different bacterial strains, effectively avoids cross-contamination, and simplifies the cleaning and sterilization process.

[0052] A plurality of fixing components 3 are provided between the placement plate 4 and the inner cavity of the outer box 1, and the inner box 2 is fixed inside each fixing component 3. The fixing components 3 are used to limit and fix the inner box 2 in the upper cavity 11 and the lower cavity 12.

[0053] The fixing component 3 includes guide plates 31 and limiting buckles 32. Several sets of guide plates 31 are arranged between the placement plate 4 and the inner cavity of the outer casing 1. Each set of guide plates 31 consists of four plates. Two guide plates 31 in each set are mounted on the side wall of the inner cavity of the outer casing 1, and two guide plates 31 are mounted on the side wall of the placement plate 4. The inner casing 2 is placed in the limiting space formed by the inner sides of the four guide plates 31. The limiting buckle 32 is detachably fastened to the front end of each guide plate 31, restricting the inner casing 2 within the guide plate 31. The guide plates 31 are L-shaped, and the four guide plates 31 in the same set are rectangularly distributed, located at the four corners of the rectangle. The inner casing 2 is placed into the limiting space enclosed by the L-shaped inner sides of the four guide plates 31. Finally, the limiting buckles 32 at the ends of the guide plates 31 prevent the inner casing 2 from detaching from the guide plates 31.

[0054] A bacterial incubator for testing includes placement plates 4, with a plurality of placement plates 4 evenly spaced from top to bottom inside the inner chamber 2. The placement plates 4 serve two purposes: firstly, to place culture units 6 on their top surface, and secondly, to allow air to pass through, thereby regulating the temperature and humidity within the inner chamber 2.

[0055] Multiple temperature and humidity sensors are installed inside the inner chamber 2 to detect the temperature and humidity at various locations, so as to adjust and maintain a stable culture environment in the inner chamber 2.

[0056] The placement plate 4 has a hollow structure, and a control component 5 is installed on the inner side of the placement plate 4 to regulate the temperature and humidity in the inner box 2.

[0057] The control component 5 includes a dispersion plate 51 and an inlet pipe 52. The top surface of the placement plate 4 has several upper holes 401 penetrating through it. Dispersion plates 51 are installed in the upper left, lower left, upper right, and lower right regions of the inner cavity of the placement plate 4. The dispersion plates 51 are hollow, and their top surfaces have several lower holes 501 penetrating through them. The diameter of the upper holes 401 is smaller than the diameter of the lower holes 501. An inlet pipe 52 is installed on one side of the dispersion plate 51. The inlet pipe 52 is connected to an external air source to adjust the temperature and humidity inside the inner chamber 2. After the external air source adjusts the temperature and humidity sequentially, it is introduced into the dispersion plate 51 through the inlet pipe 52, then passes through the lower holes 501 and the upper holes 401 sequentially, entering the inner chamber 2 to adjust the temperature and humidity inside the inner chamber 2. The temperature and humidity control structure of the air source is common knowledge known to those skilled in the art. Those skilled in the art can choose the appropriate machine to achieve temperature and humidity control of the air source and adjust the air introduced into the inner box 2 to the required temperature and humidity.

[0058] When air is forced into the bottom of the incubator through the pipes, the airflow typically has a high velocity and significant dynamic pressure. The large pores in the lower layer, namely the lower pore 501, primarily function as a throttling and diffusion mechanism. As air enters the interlayer between the two plates through the lower pore 501, the flow area suddenly increases, the airflow velocity decreases significantly, and the dynamic pressure is converted into static pressure. This causes the air pressure within the interlayer to tend towards equilibrium, eliminating the localized high-pressure zones introduced by the inlet pipe 52, and laying the foundation for subsequent uniform airflow.

[0059] After being pressurized by the interlayer, the air needs to pass through the small hole on the top surface of the upper layer, namely the upper hole 401, to enter the inner box 2. The upper hole 401 acts as a second resistance relative to the interlayer space. Since the pressure inside the interlayer is already balanced, the airflow across the entire surface of the placement plate 4 becomes very uniform. At the same time, the upper hole 401 divides a large airflow into countless smaller airflows, and also avoids large eddies and turbulence.

[0060] Through the design of two layers of holes, the air flow is transformed from a "jet" to a "percolation". Instead of being violently blown into the inner chamber 2, it spreads slowly and gently upwards. This is crucial for bacterial culture, as violent airflow can lead to accelerated evaporation of the culture medium or disrupt the culture environment, causing drastic fluctuations in the culture environment.

[0061] The dispersion plate 51 has several partition plates 502 arranged along its length, dividing the inner cavity of the dispersion plate 51 into several dispersion chambers 503. Each dispersion chamber 503 has an inlet pipe 52 installed on one side, and each dispersion chamber 503 has several lower-layer holes 501 penetrating through its top surface. The design of the dispersion chambers 503, in conjunction with the four positions of the dispersion plate 51, allows for independent control of the zones. Depending on the bacterial culture requirements, air of different temperatures and humidity levels can be introduced into different dispersion chambers 503 through different inlet pipes 52, thereby adjusting the culture environment within the inner chamber 2.

[0062] If the temperature in a certain corner of the inner chamber 2 is too high, the gas flow, temperature and humidity below the corresponding area can be adjusted separately to achieve a function similar to regional environmental compensation, ensuring that the temperature and humidity of the entire culture environment in the inner chamber 2 are uniform.

[0063] A bacterial culture chamber for testing includes culture units 6, with a plurality of culture units 6 detachably placed on the top surface of a placement plate 4. The culture units 6 are used for bacterial culture. The culture units 6 are arranged in horizontal and vertical rows and columns, with access channels between each row of culture units 6 and on the right side of the placement plate 4, facilitating the movement of an access component 7 through these channels to access and place a specific culture unit 6.

[0064] The top surface of the placement plate 4 is equipped with several sets of limiting angle plates, each set of the limiting angle plates consists of 4 plates, and the culture unit 6 is placed inside the limiting angle plates of each set.

[0065] The culture unit 6 includes a base 61, a fence frame 62, a test tube holder 63, and culture test tubes 65. The fence frame 62 is located on the outer side of the base 61, and the test tube holder 63 is installed on the inner side of the fence frame 62. The culture test tubes 65 are fixed inside the test tube holder 63. A positioning hole is provided on the top surface of the base 61, and the bottom end of the culture test tube 65 is located within the positioning hole. When placing the culture test tube 65, first place the bottom end of the culture test tube 65 into the positioning hole, then activate the test tube holder 63 to fix the test tube from both sides and the rear side, achieving three-point positioning for a secure fixation.

[0066] The test tube fixing component 63 includes a side grid plate 631, a side mounting plate 632, a side fixing push rod 633, a side connecting plate 634, a linkage protrusion 635, a slide rail 636, a slider 637, a rear mounting box 641, a rear fixing push rod 642, a rear connecting plate 643, a rear ear plate 644, and a limiting band 645. The fence frame 62 is rotatably connected to both sides of the side grid plate 631. Side mounting plates are respectively provided on both sides of the fence frame 62. A side fixing push rod 633 is installed on one side of each side mounting plate, and a side connecting plate 634 is provided at the output end of the side fixing push rod. Both ends of the side connecting plate 634 are provided with linkage protrusions 635. A slide rail 636 is installed on the outer side of the side grid plate 631. A slider 637 is slidably connected in the slide rail 636. The slider 637 is rotatably connected to the linkage protrusions 635. The side fixed push rod 633 is an electric push rod that can extend and retract. Through the side connecting plate 634 and the linkage protrusions 635, it drives the slider 637 to move along the slide rail 636, thereby realizing the rotation of the side grid plate 631, which contacts the culture tube 65 and limits and fixes both sides of the culture tube 65.

[0067] A rear mounting box 641 is installed on the rear side of the fence frame 62. The front end of the rear mounting box 641 is open. A rear fixing push rod 642 is installed on the rear side wall of the inner cavity of the rear mounting box 641. A rear connecting plate 643 is provided at the output end of the rear fixing push rod 642. Rear ear plates 644 are respectively provided on both sides of the rear connecting plate 643. Several limiting bands 645 are provided between the two rear ear plates 644. The rear fixing push rod 642 is an electric push rod that can be extended and retracted. Through the rear connecting plate 643 and the rear ear plates 644, it drives the limiting bands 645 to press against the rear side of the culture tube 65, thereby limiting and fixing the rear side of the culture tube 65. The limiting bands 645 cooperate with the two side grid plates 631 to achieve three-point positioning, making the fixation of the culture tube 65 very secure.

[0068] A bacterial incubator for testing includes a pick-and-place component 7. The pick-and-place component 7 is installed on the top surface of the placement plate 4 for picking up and placing the culture unit 6. This avoids collisions between the culture tubes 65 during the picking and placing process and reduces the impact on the culture environment in the inner chamber 2.

[0069] The pick-and-place assembly 7 includes a walking frame 71, a walking mounting plate 72, a walking push rod 73, a walking guide rail 74, a moving platform 75, a pick-and-place push rod 76, a pick-and-place frame 77, and electromagnets 78. The walking frame 71 is provided on the top surface of the placement frame, the walking mounting plate 72 is provided on the rear side of the walking frame 71, the walking push rod 73 is installed on the front side of the walking mounting plate 72, a set of walking guide rails 74 is installed on the bottom surface of the top wall of the walking frame 71, the moving platform 75 is slidably connected to the walking guide rails 74, the output end of the walking push rod 73 is fixedly connected to the moving platform 75, the pick-and-place push rod 76 is installed on the slider 637 of the moving platform 75, the pick-and-place frame 77 is installed on the output end of the pick-and-place push rod 76, the pick-and-place frame 77 is adapted to the fence frame 62, and several electromagnets 78 are installed on the bottom surface of the pick-and-place frame 77. The moving platform 75 is a linear motor platform, and its output slider 637 can move along the platform, thereby driving the pick-and-place push rod 76 to move left and right. Both the walking push rod 73 and the pick-and-place push rod 76 are electric push rods and are telescopic. The extension and retraction of the walking push rod 73 drives the moving platform 75 to move back and forth along the walking guide rail 74; the extension and retraction of the pick-and-place push rod 76 drives the pick-and-place frame 77 to move up and down. When picking up or placing the culture unit 6, the walking push rod 73 is activated, driving the moving platform 75 to the rear of the culture unit 6. Then, the activation of the walking push rod 73 drives the pick-and-place push rod 76 and the pick-and-place frame 77 to move. When the pick-and-place frame 77 moves directly above the culture unit 6, the pick-and-place push rod 76 is activated, driving the pick-and-place frame 77 downwards until the electromagnet 78 contacts the top surface of the fence frame 62. At this time, the electromagnet 78 is activated, firmly adhering the culture unit 6 to the bottom surface of the pick-and-place frame 77. Finally, the pick-and-place push rod 76 moves upward, causing the culture unit 6 to disengage from the limiting angle plate. Then, the moving platform 75 and the walking push rod 73 are activated, moving the culture unit 6 along the pick-and-place channel until it reaches the foremost side. When the inner box 2 is closed, the culture unit 6 stops moving at the foremost side of the inner box 2's cavity. Once the inner box 2 is opened, the walking push rod 73 resumes its operation, causing the culture unit 6 to extend to the front of the inner box 2. If the inner box 2 is opened, the culture unit 6 is directly extended to the front of the inner box 2.

[0070] Several buttons are provided on the outside of the inner box 2, each corresponding to a culture unit 6. After pressing a button, the culture unit 6 is taken out by the pick-and-place component 7.

[0071] When using this invention:

[0072] Place the culture tube into the culture unit. During placement, first open the outer box and the corresponding inner box. The moving push rod is activated, moving the moving platform to the rear of the culture unit. Then, the moving platform moves the pick-and-place push rod and the pick-and-place frame. When the pick-and-place frame is directly above the culture unit, the pick-and-place push rod is activated, moving the pick-and-place frame downwards until the electromagnet contacts the top surface of the enclosure frame. At this point, the electromagnet activates, firmly attaching the culture unit to the bottom surface of the pick-and-place frame. Finally, the pick-and-place push rod moves upwards, disengaging the culture unit from the limiting angle plate. Then, the moving platform and the moving push rod are activated, moving the culture unit along the pick-and-place channel until it reaches the front, extending the culture unit to the front of the inner box.

[0073] Then, the bottom end of the culture tube is placed into the positioning hole. The side fixing push rod is activated and extends / retracts, driving the slider to move along the slide rail via the side connecting plate and the linkage protrusion. This allows the side grid plate to rotate and contact the culture tube, limiting and fixing both sides of the culture tube. The rear fixing push rod is an electric push rod that extends and, via the rear connecting plate and the rear ear plate, drives the limiting band to press against the rear side of the culture tube, limiting and fixing the rear side of the culture tube. The limiting band, in conjunction with the two side grid plates, achieves three-point positioning, making the culture tube very securely fixed.

[0074] After the culture tube is placed, the pick-and-place component is activated, which drives the culture unit back to its original position and places it inside the limiting angle plate.

[0075] When it is necessary to remove a culture tube, the same procedure as described above should be followed.
