Description

Technical Field

[0001] This utility model relates to the field of cell dispensing technology, specifically to a cell dispensing device. Background Technology

[0002] Cell dispensing equipment is mainly used for quantitative and aseptic dispensing of cell suspensions or cell-containing samples, ensuring minimal error in the number and volume of cells in each sample while avoiding cell contamination. It also enables batch processing through automated parameter settings, improving the efficiency of experimental or clinical operations. It is widely used in cell culture, drug testing, cell therapy dosage dispensing and other scenarios.

[0003] While existing equipment is suitable for general liquid dispensing scenarios, its reliance on passive cooling methods such as ice packs for cell dispensing fails to maintain the stringent temperature control required by cells. This results in significant fluctuations in cell viability, poor temperature stability, and low energy utilization. Furthermore, the use of static storage containers and open piping interfaces, typical of chemical liquid dispensing, causes the cell suspension within the mother cell bag to gradually separate due to gravity. This leads to a significant drop in sample concentration in the later stages of dispensing compared to the initial value, resulting in high concentration deviations and a high risk of microbial contamination and batch-to-batch cross-contamination. In addition, dispensing using time-volume conversion or coarse weighing methods, with its single-variable time control mode, is susceptible to changes in fluid viscosity, leading to high dispensing errors at microliter levels.

A cooling module is located on one side of the weighing feedback module and the electric cylinder mixing module, and is used to cool and maintain the ambient temperature of the cell daughter bag and the cell mother bag.

[0012] As a further description of the above technical solution, the disinfection and sterilization module includes an ultraviolet lamp, which is disposed on the inner wall of the outer casing.

[0013] As a further description of the above technical solution, an installation plate is provided inside the outer shell, and a heat insulation layer is filled between the installation plates.

[0014] As a further description of the above technical solution, a central control screen is installed on one side of the outer shell via a robotic arm. The central control screen is electrically connected to the weighing unit, liquid level sensor, peristaltic pump, drive motor, first refrigeration device, second refrigeration device, and ultraviolet lamp.

[0015] The beneficial effects of this utility model are as follows: 1. In this utility model, the weighing unit is installed below each cell sub-bag via fixed terminals.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figures 1-7 As shown, in one embodiment, a cell dispensing device includes an outer shell 1, and the outer shell 1 is provided with a weighing feedback module 2, a cell filling module 3, an electric cylinder mixing module 4, a cooling module 5, a ventilation and heat dissipation module 6, and a disinfection and sterilization module 7. For example, the weighing feedback module 2 is disposed inside one side of the outer casing 1 and is used to weigh and provide feedback on the weight change of the cell suspension injected into the cell sub-bag; In some embodiments, the weighing feedback module 2 includes multiple sets of parallel fixed terminals 21, and each set of fixed terminals 21 is integrated with a weighing unit 22 on its top. The weighing unit 22 has a built-in high-precision strain gauge weighing sensor, which captures the small deformation of the elastic element after bearing the load and converts the mechanical signal into an electrical signal, which can accurately identify the weight change during the cell suspension injection process. In some embodiments, each weighing unit 22 has a corresponding cell sub-bag placed on it, and a U-shaped clamping plate 23 is installed on the fixed terminal 21 and the outside of the weighing unit 22, which not only reduces the interference of its own weight on the weighing accuracy, but also provides stable lateral restraint for the sub-bag. In some embodiments, the clamping plate 23 is suspended inside the housing 1 by the first support plate 24 to ensure that the entire weighing assembly does not shake during equipment operation, further ensuring the stability of the weighing data.

[0021] In some embodiments, a first clamp valve 26 is suspended on the top of the clamping plate 23 via a second support plate 25, a second clamp valve 27 is installed on the top of the first clamp valve 26, and a liquid level sensor 28 is installed on one side of the second clamp valve 27. The delivery pipeline inserted at the top of the cell subbag is clamped sequentially on the first clamp valve 26, the liquid level sensor 28, and the second clamp valve 27. This allows for both on / off control of the pipeline through the clamp valves and real-time monitoring of the suspension level in the pipeline through the liquid level sensor 28, thus avoiding problems such as dry suction or overflow.

[0022] Understandably, the pneumatic pipe clamp valve achieves the clamping or releasing of the pipeline through automatic control components such as solenoid valves. It has a compact and simple structure, is easy to maintain, has high working efficiency and a long service life, and can quickly, efficiently and safely replace different pipelines, reducing downtime and improving work efficiency. The weighing unit 22 is installed below each cell sub-bag through the fixed terminal 21. When the cell suspension is injected into the sub-bag, the weighing sensor will transmit the weight data to the central control screen 9 at a fixed frequency. The central control screen 9 compares the preset target weight value with the actual measured value. If the deviation exceeds the preset value, it will automatically adjust the speed of the peristaltic pump 31 and dynamically correct the filling flow rate, ultimately ensuring that the filling volume error of each cell sub-bag is controlled within the preset value, realizing high-precision quantitative dispensing.

[0023] Please continue reading. Figures 1-7 In this embodiment, the cell filling module 3 is disposed on one side of the weighing feedback module 2 and is used to squeeze the delivery pipeline to deliver the cell suspension to the cell mother bag. In some embodiments, the cell filling module 3 includes a peristaltic pump 31, which is disposed on one side of the clamping plate 23. The delivery pipe inserted at the top of the cell sub-bag extends through the delivery pump and communicates with the cell mother bag. In order to adapt to cell mother bags and cell sub-bags of different specifications, the delivery pipe provides a variety of inner diameters. The central control screen 9 can automatically calculate and set the rotation speed of the peristaltic pump 31 according to the inner diameter of the pipe and the target flow rate.

[0024] Understandably, the use of a high-performance peristaltic pump 31 as the power source for liquid transport, which delivers cell suspension through the squeeze delivery pipeline, allows for the injection of accurate doses of cell suspension into each cell sub-bag according to preset flow rates and time intervals during the filling process. This delivery method is gentle and without shear force, which can protect cells from damage to the greatest extent.

[0025] Please continue reading. Figures 1-7 In this embodiment, the electric cylinder mixing module 4 is disposed on one side of the cell filling module 3 and is used to drive the tapping of the cell mother bag to mix the cell suspension. In some embodiments, the electric cylinder mixing module 4 includes a drive motor 41, which is a servo motor with strong speed controllability and high positioning accuracy. In some embodiments, the drive motor 41 is connected to the drive cylinder 42, which can convert the rotational motion of the motor into the linear reciprocating motion of the telescopic rod 43. The stroke adjustment range of the telescopic rod 43 can be flexibly set according to the volume of the mother bag. In some embodiments, the drive cylinder 42 is connected to the mixing support 44 via a telescopic rod 43. The mixing support 44 is equipped with a mixing support plate 45 at the bottom, which can accommodate mother bags of different widths. In some embodiments, the height of the mixing support plate 45 corresponds to 1 / 4 to 1 / 3 of the bottom of the cell mother bag, so that when the mixing support plate 45 squeezes the cell mother bag, it can squeeze the bottom of the cell mother bag, thereby facilitating the mixing of the cell stock solution in the cell mother bag.

[0026] In some embodiments, a protective portion is provided on the side wall of the mixing support plate 45 that abuts against the cell mother bag. This protective portion protects the surface of the cell mother bag, preventing damage to its surface when the mixing support plate 45 comes into contact with the cell mother bag. Specifically, the protective portion can be made of an elastic material such as rubber.

[0027] In some embodiments, the corner of the mixing support plate 45 that contacts the storage bag is rounded, so as to avoid sharp points from scratching and damaging the surface of the cell mother bag when the mixing support plate 45 contacts the surface of the cell mother bag.

[0028] In some embodiments, the top of the mixing support 44 may also be optionally provided with a hook, which allows the round hole at the top of the cell mother bag to pass through the hook for fixation.

[0029] Understandably, the electric cylinder mixing module 4 is equipped with a high-precision drive electric cylinder 42. By rotating and flipping the drive electric cylinder 42, the telescopic rod 43 is driven to make the mixing support 44 reciprocate to the surface of the cell mother bag according to the cell type and dispensing requirements, so as to fully mix the cells in the mother liquor, make them evenly distributed, and ensure that the cell suspension extracted each time has the same concentration.

[0030] Please continue reading. Figures 1-7 In this embodiment, the cooling module 5 is located on one side of the weighing feedback module 2 and the electric cylinder mixing module 4, and is used to cool and maintain the ambient temperature of the cell daughter bag and the cell mother bag. In some embodiments, the cooling module 5 includes a first cooling device 51 and a second cooling device 52. The first cooling device 51 is disposed on one side of the first support plate 24, and its cuboid cooling end along the direction of the back end face of the first support plate 24 directly faces the placement area of ​​the cell daughter bag. The second cooling device 52 is disposed on one side of the mixing support 44, and its cuboid cooling end along the direction of the back end face of the mixing support 44 directly faces the placement area of ​​the cell mother bag.

[0031] In some embodiments, the refrigeration device employs a semiconductor refrigeration device or a compressor. Semiconductor refrigeration devices are suitable for low-load applications, offering high temperature control accuracy, noiselessness, and small size, and their cooling power can be infinitely adjusted by regulating the current. Compressor refrigeration systems, on the other hand, are suitable for high-load applications, providing rapid cooling and stable cooling capacity to meet the needs of continuous batch packaging. Both types of refrigeration devices are equipped with temperature sensors (as prior art, these are not included in the design). Figure 3 As shown in the diagram, sensors are positioned at corresponding locations in the weighing and mixing zones to collect ambient temperature data in real time and transmit the data to the central control screen 9. The temperature control algorithm built into the central control screen 9 automatically adjusts the operating status of the refrigeration device based on the deviation between the set temperature and the actual temperature. Simultaneously, insulation cotton is also attached to the side walls of the weighing and mixing zones (as is existing technology, this is not shown in the diagram). Figure 3 As shown in the figure, it can form a localized, sealed, and insulated space, keeping the temperature fluctuations within the area within a low range and reducing the fluctuations in cell survival rate caused by temperature instability.

[0032] Understandably, the refrigeration device can quickly reduce and stably maintain the ambient temperature of the cell mother bag and cell daughter bag to a suitable range, ensuring that the cells are kept in a low-temperature preservation state throughout the entire packaging process; at the same time, the refrigeration module has an intelligent temperature control function, which can automatically adjust the refrigeration power according to the ambient temperature and load, so as to ensure the refrigeration effect and save energy. Please continue reading. Figures 1-7In this embodiment, the ventilation and heat dissipation module 6 is disposed on one side of the cooling module 5 and is used to dissipate the heat generated by the cooling module 5. In some embodiments, the ventilation and heat dissipation module 6 includes a cooling fan 61, which is symmetrically installed on both sides of the housing 1. One set of cooling fans 61 is connected to the first cooling device 51 through a ventilation duct, and the other set of cooling fans 61 is connected to the second cooling device 52 through a ventilation duct. Understandably, the cooling fan 61 is connected to the cooling device through the ventilation duct. The airflow of the cooling fan 61 can be dynamically adjusted according to the cooling power. The airflow driven by the fan can exhaust the heat generated by the cooling device through the ventilation duct, avoiding the impact of heat accumulation on the performance of the equipment and cell quality. A filter device is installed at the ventilation port to effectively prevent external dust and other impurities from entering the equipment.

[0033] Please continue reading. Figures 1-7 In this embodiment, the disinfection and sterilization module 7 is disposed on one side of the electric cylinder mixing module 4 and is used to disinfect the internal surface of the sterilization equipment, the surface of the pipeline, and the internal components.

[0034] In some embodiments, the disinfection and sterilization module 7 includes an ultraviolet lamp 71, which is disposed on the inner wall of the outer casing 1. Specifically, it can be disposed on the periphery, top and bottom of the inner wall of the outer casing 1, and can completely cover the key positions of the weighing area, filling area and mixing area to ensure no sterilization dead corners.

[0035] Understandably, the ultraviolet lamp 71 is installed on the inner wall of the outer casing 1 and can be automatically turned on periodically before, during, and after the equipment is shut down to thoroughly disinfect and sterilize the internal surfaces of the equipment, the pipe surfaces, and the internal components. This effectively kills bacteria, viruses, and other microorganisms in the air and on the surfaces of objects, ensuring that the entire dispensing process is carried out in a sterile environment and preventing cell contamination. It should be noted in detail that a mounting plate 11 is provided inside the outer casing 1. The mounting plate 11 is fixed to the frame of the outer casing 1 with bolts, and the installation position can be flexibly adjusted according to the module size, improving the scalability of the equipment; a thermal insulation layer is filled between the mounting plates 11 (as prior art, this is not included). Figure 3 As shown in the figure, the insulation layer uses polyurethane foam as the insulation layer, which can effectively block the heat transfer between the inside and outside of the equipment and maintain the internal low temperature environment in conjunction with the refrigeration module.

[0036] Furthermore, a central control screen 9 is installed on one side of the outer casing 1 via a robotic arm 8. The robotic arm 8 can adjust the direction and position of the central control screen 9 to facilitate operation by the operator while standing or sitting. The central control screen 9 is electrically connected to the weighing unit 22, liquid level sensor 28, peristaltic pump 31, drive motor 41, first refrigeration device 51, second refrigeration device 52, and ultraviolet lamp 71. The screen can display the working status of each module in sections. Abnormal situations will be indicated by audible and visual alarms, and the cause of the fault will be displayed. The operator can input parameters such as target weight, temperature, tapping frequency, and disinfection time through the touch interface. The system automatically saves the parameter templates, which can be directly recalled for the next use.

[0037] Specifically, the built-in computer module of the central control screen 9 can collect various data during the equipment assembly process in real time and store them in the database. It can also query, statistically analyze, and perform analysis on the collected data. Through reasonable configuration and optimization, it can improve the system's flexibility and scalability, and significantly enhance production efficiency and data management capabilities.

[0038] Understandably, the outer casing 1 is divided into different functional areas. The equipment has a three-layer structure. The insulation layer uses polyurethane foam as the insulation layer, which can effectively reduce heat transfer and maintain a stable low-temperature environment inside the equipment. Together with the central control screen 9, the various modules can work together, resulting in a high degree of automation, reducing the need for manual intervention, shortening the production cycle, and reducing labor intensity and production costs.

[0039] Through the above technical solutions, the cell dispensing equipment of this application can ensure the quality and efficiency of cell dispensing from multiple dimensions: the electric cylinder mixing module 4 ensures uniform concentration of cell mother liquor, and, together with the weighing feedback module 2, achieves precise closed-loop control of cell sub-bag volume, making the cell quantity and concentration of each sub-bag highly consistent, effectively improving product quality stability; the constant low-temperature environment provided by the cooling module 5, combined with the peristaltic conveying method of the cell filling module 3, can reduce the temperature shock and mechanical damage to cells, maintaining normal physiological functions and metabolic activity of cells; the ventilation and heat dissipation module 6, through reasonable design and efficient operation, promptly removes excess heat from the equipment, ensuring stable and reliable operation of the equipment while avoiding adverse effects of heat on cells; the disinfection and sterilization module 7 comprehensively covers key areas inside the equipment, effectively killing various microorganisms, reducing the risk of contamination, and providing a safe and reliable operating space for cell culture and processing; at the same time, the equipment relies on the central control screen 9 to realize the collaborative work of various modules, with a high degree of automation, greatly reducing the need for manual intervention, which not only shortens the production cycle but also reduces labor intensity and production costs.
