Description

Technical Field

[0001] This utility model relates to the field of dispensing devices, and more particularly to a culture medium dispensing device. Background Technology

[0002] Culture media are mixtures of nutrients specifically used in fields such as microbiology, cell biology, and plant tissue culture. They provide microorganisms, cells, or tissues with the necessary nutrients, growth factors, and environmental conditions to support their growth, reproduction, and metabolic activities. Culture media dispensing devices are equipment used to accurately and efficiently dispense culture media into various containers, with different dispensing modes selected according to experimental needs.

[0003] Existing dispensing equipment typically uses a pressure dispenser to control the opening and exit of the clamp valve during the dispensing process. Since the culture medium has a certain viscosity, residue may be left during the dispensing process, resulting in a discrepancy between the actual dispensing capacity and the set value. This affects the accuracy of the dispensing work, requires frequent adjustments and corrections, and reduces overall production efficiency.

[0004] Therefore, given the viscosity of the aforementioned culture medium, residues may occur during the dispensing process, leading to discrepancies between the actual dispensed volume and the set value. This affects the accuracy of the dispensing work, necessitates frequent adjustments and corrections, and reduces overall production efficiency. A culture medium dispensing device can be designed to control the quantitative outflow of liquid, achieving automatic quantitative dispensing of the culture medium. This device can perform designated dispensing work on solution bottles of different specifications and sizes. Furthermore, the operating interval of the device can be controlled by a control module to avoid residues caused by the viscosity of the culture medium, which could result in insufficient dispensing volume. This also prevents dispensing volumes from being too high or too low, ensuring the accuracy of the dispensing volume. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Culture media are specially formulated mixtures of nutrients designed to support the growth and reproduction of microorganisms, plants, or animals. They are nutrient substrates composed of different combinations of nutrients, generally containing carbohydrates, nitrogenous substances, inorganic salts (including trace elements), vitamins, and water. The most basic use of culture media is for culturing bacteria and other microorganisms. Through culture media, scientists can study the growth rate, nutritional requirements, and metabolic products of microorganisms, thereby gaining a better understanding of their characteristics and functions. In the medical field, culture media are used for the isolation and identification of bacteria and viruses. Doctors typically collect microorganisms from patient samples and inoculate them onto appropriate culture media to obtain pure cultures of bacteria or viruses, thereby determining whether the patient is infected with a specific microorganism and selecting appropriate drugs for treatment. Culture media also play a crucial role in the food industry. In the food industry, it is often necessary to detect the presence of pathogenic bacteria or microorganisms that cause food spoilage. By inoculating food samples into specific selective culture media, specific microorganisms can be selectively cultured, and the quality of the food can be determined. Quality control of culture media is extremely important, encompassing both physicochemical and microbiological testing methods. Physicochemical testing methods include pH measurement and gel strength measurement, while microbiological testing methods are divided into quantitative and semi-quantitative tests on solid and liquid culture media, as well as qualitative tests. Culture media are indispensable tools in fields such as microbiology, cell biology, and plant tissue culture; their quality and preparation methods directly affect the accuracy and reliability of experimental results.

[0023] Culture medium dispensing devices are specialized laboratory equipment for automatically dispensing culture media, converting large volumes into smaller volumes in test tubes, bottles, etc., to meet diverse experimental needs. During dispensing, the device controls the opening and closing times of the clamp valves and maintains a pre-selected, continuous low residual pressure within the media container to ensure controlled media flow. These devices are widely used in pharmaceutical, food, disease control, and environmental media preparation and petri dish dispensing. They are efficient, precise laboratory equipment that minimizes human error and contamination risks.

[0024] Although there are various culture medium dispensing devices on the market, some problems still exist in actual use: existing dispensing devices usually use pressure dispensers to control the opening and closing of clamp valves during the dispensing process. Since the culture medium has a certain viscosity, residues may occur during the dispensing process, resulting in the actual dispensing capacity not matching the set value, affecting the accuracy of the dispensing work, requiring frequent adjustments and corrections, and reducing overall production efficiency.

[0025] Please see Figures 1-4This utility model provides an embodiment of a culture medium dispensing device, including a workbench 1 and a dispensing and sterilization assembly; the upper end of the workbench 1 is equipped with a dispensing and sterilization assembly for dispensing and sterilizing culture medium, the dispensing and sterilization assembly including a material bin 201, a transfer block 202, a transfer plate 204, a solenoid valve 206, a conveying pipe 207, a metering strip 208, a fixing frame 211, a drive motor 213, a support plate 214, a support spring 217, and a sterilization box 218, the material bin being fixedly installed at the upper end of the workbench 1. 201. A transmission block 202 is connected to the upper end of the material bin 201. A transmission plate 204 is fixedly installed at the outer end of the transmission block 202. A connector 205 is fixedly installed at the lower end of the transmission plate 204. A transmission pump is provided between the transmission plate 204 and the material bin 201. An electromagnetic valve 206 is fixedly installed at the outer end of the connector 205. A control module 203 is fixedly installed on the outer side of the material bin 201. A connecting cable 210 is provided between the electromagnetic valve 206 and the control module 203. The battery valve is electrically connected to the control module 203.

[0026] Please see Figures 1-2 In this embodiment, a feeding pipe 209 is connected to the outer end of the material tank 201, and a control valve is fixedly installed at the outer end of the feeding pipe 209. A transparent observation plate is fixedly installed at the outer end of the material tank 201, and a metering strip 208 is fixedly installed on the outer wall of the transparent observation plate. By using the transparent observation plate in conjunction with the metering strip 208 to observe the solution volume inside the material tank 201, the remaining amount of culture medium can be monitored in real time. When the solution volume is insufficient, it can be replenished in time to avoid affecting the experimental progress due to insufficient solution. At the same time, monitoring the solution volume can ensure the rational use of culture medium and reduce [the risk of infection]. To minimize waste due to insufficient solution volume and save costs, a feed pipe 207 is provided at the end of the connector 205 away from the transmission plate 204. A threaded sleeve is fixed at one end of the feed pipe 207, and a threaded hole is opened at one end of the connector 205. The feed pipe 207 is threadedly fixed to the connector 205 through the threaded sleeve. By replacing the feed pipe 207 with a suitable length according to the solution bottle 216 of different capacity, leakage caused by the feed pipe 207 being too short can be effectively avoided, making it adaptable to various sizes of containers and maintaining a clean working environment.

[0027] Please see Figures 1-3In this embodiment, a fixed frame 211 is welded to the outer end of the workbench 1. A drive motor 213 is fixedly installed inside the fixed frame 211. One end of the drive motor 213 is located inside the fixed frame 211 and has a drive rod 212. A support plate 214 is sleeved on the outer wall of the drive rod 212. By using the drive motor 213 connected to the drive rod 212 to drive the support plate 214 containing the solution bottle 216 to rotate and dispense the solution, a fast and continuous dispensing process is achieved, reducing the time required for manual dispensing and reducing the emissions generated during the dispensing process. To reduce errors and improve overall dispensing efficiency, multiple sets of support springs 217 are fixedly installed inside the fixed frame 211. A load-bearing block is provided at the end of the support spring 217 away from the fixed frame 211. The support spring 217 is fitted to the bottom of the support plate 214 through the load-bearing block. A spring rubber damper is provided on the inner side of the support spring 217. By using the support spring 217 to support the rebound of different support plates 214 for rotation and dispensing, the dispensing of solution bottles 216 of different weights and sizes is stabilized, adapting to different dispensing needs and improving the scope of use of the equipment.

[0028] Please see Figures 2-4 In this embodiment, the upper end of the support plate 214 is provided with through holes, and each through hole is provided with a solution bottle 216. The end of the drive rod 212 away from the fixed frame 211 is provided with a limiting block 215. The limiting block 215 is fastened and fixed to the drive rod 212. By using the limiting block to fasten and limit the support plate 214 after installation, displacement or tilting during the dispensing process is prevented, reducing operational risks and improving overall stability. The outer end of the workbench 1 is fixed with a sterilization box 218. The sterilization box 218 is electrically connected to the control module 203. The sterilization box 218 is provided with multiple sets of support plates 219. By using the sterilization box 218 to seal and sterilize the dispensed culture medium, a closed sterile environment is provided to maintain the sterile state of the culture medium and ensure the quality of the culture medium is stable and reliable.

[0029] During operation, firstly, select a suitable support plate 214 based on the solution bottle 216 to be dispensed. Place the solution bottle 216 into the through hole of the support plate 214 for support. After replacing the solution bottle 216 with a different capacity, pull out the limit buckle at one end of the drive rod 212, and fit the support plate 214 onto the outer wall of the drive rod 212. Use the support spring 217 to connect the load-bearing block to rebound and support the support plate 214. At the same time, fasten the limit buckle to the drive rod 212 to fix it, stabilizing the dispensing of solution bottles 216 of different weights and sizes, adapting to different dispensing needs, and preventing displacement or tilting during the dispensing process. After the solution bottle 216 is installed, according to the replacement of solution bottles with different capacities... The liquid bottle 216 is fitted with a corresponding delivery tube 207, which is threadedly fixed to the connector 205 via a threaded sleeve. The rebound effect of the support spring 217 aligns the set of solution bottles 216 inside the support plate 214 with one end of the delivery tube 207, preventing leakage due to the delivery tube 207 being too short. This allows it to adapt to various container sizes. After the delivery tube 207 is replaced, the drive motor 213, connected to the drive rod 212, is activated first to rotate the support plate 214 to the bottom of the delivery tube 207 at a preset rotation speed and angle. Next, the control module 203 controls the transfer pump to deliver the culture medium, according to the dispensing solution bottles. The capacity control solenoid valve 206 of 216 opens to discharge material. When the discharge volume reaches a certain value, the solenoid valve 206 closes. The control module 203 controls the operating interval of the equipment to prevent the culture medium from leaving residues that could lead to insufficient dispensing volume. After the solution inside the delivery pipe 207 has drained, the drive motor 213 rotates the support plate 214 again to add material to the second set of solution bottles 216. The control module 203 controls the solenoid valve 206 to precisely discharge the material, controlling the quantitative flow of liquid and achieving automatic quantitative dispensing of the culture medium. It can also perform designated dispensing work on solution bottles 216 of different specifications and sizes to avoid dispensing too much or too little material. During the filling process, the remaining amount of culture medium in the material box 201 is monitored in real time by using a transparent observation plate and measuring strip 208 to observe the solution volume. When the solution volume is insufficient, it is replenished in time to avoid affecting the experimental progress due to insufficient solution. At the same time, monitoring the solution volume can ensure the rational use of culture medium and reduce waste caused by insufficient solution. After the various solution bottles 216 are filled, the support plate 214 is removed and placed in the sterilization box 218. The control module 203 controls the sterilization box 218 to seal and sterilize the filled culture medium, providing a closed sterile environment, maintaining the sterility of the culture medium, ensuring the stability of the quality of the culture medium, and realizing the filling of culture medium.

[0030] Through the above steps, the control module 203 controls the electromagnetic valve 206 to precisely dispense the liquid, controlling the quantitative outflow of liquid and realizing automatic quantitative dispensing of culture medium, improving the overall dispensing efficiency. Simultaneously, controlling the quantitative dispensing of culture medium allows for designated dispensing of solution bottles 216 of different specifications and sizes, avoiding excessive or insufficient dispensing and ensuring the accuracy of the dispensing volume. Furthermore, a transparent observation plate combined with a metering strip 208 is used to observe the solution volume inside the material tank 201, monitoring the remaining amount of culture medium in real time. When the solution volume is insufficient, it is replenished promptly to avoid affecting the experimental progress due to insufficient solution. Monitoring the solution volume also ensures the rational use of culture medium, reducing waste caused by insufficient solution and saving costs. At the same time, the sterilization chamber 218 is used to seal and sterilize the dispensed culture medium, providing a closed sterile environment to maintain the sterility of the culture medium and ensure its stable and reliable quality.
