BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 It is a system block diagram of the fully enclosed aseptic connection type mRNA-LNP preparation automated encapsulation system of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples.

[0026] The invention provides as Figure 1 shown, a fully enclosed aseptic connection type mRNA-LNP preparation automated encapsulation system, including a sterile operation chamber for providing a fully enclosed sterile operation environment. The sterile operation chamber includes a laminar flow device installed on the inner top surface of the sterile operation chamber. The inner wall of the sterile operation chamber is provided with a self-cleaning coating, and the sterile operation chamber is also equipped with a pressure monitoring unit;

[0027] The laminar flow device generates laminar air flow in the vertical or horizontal direction, ensuring that the air cleanliness in the cabin reaches ISO Class 5. The laminar flow device is connected to the pressure monitoring unit through a data cable and automatically adjusts the air flow parameters according to the pressure change. The self-cleaning coating removes surface contaminants through photocatalysis or electrostatic adsorption to ensure the cleanliness of the cabin inner wall. The pressure monitoring unit monitors the cabin pressure in real time to ensure the stability of the aseptic environment and transmits the pressure data to the control system module. The laminar flow device filters the air through a high-efficiency filter to form a laminar air flow, blowing the particulate matter and microorganisms in the air towards the ground or a specific air outlet, thereby maintaining a high cleanliness in the cabin. The pressure monitoring unit can detect whether the cabin pressure is within the set range. If the pressure changes, it indicates that there may be air leakage or other problems. At this time, the laminar flow device will automatically adjust the air flow parameters to maintain the aseptic environment. The self-cleaning coating decomposes organic contaminants through photocatalytic reactions or adsorbs particulate matter on the coating surface through electrostatic adsorption to prevent the accumulation of contaminants, providing a sterile and clean operating environment for the encapsulation of mRNA-LNP preparations, ensuring that the preparations are not contaminated by external microorganisms and particulate matter during the production process, and guaranteeing the product quality and safety.

[0028] The automated conveying module is used to convey the raw materials or semi-finished products of mRNA-LNP preparations to the encapsulation station in the aseptic operation cabin according to a preset path. The automated conveying module includes a multi-track conveying system, a positioning sensor, and a speed controller. Each track of the multi-track conveying system corresponds to a different type of raw material or semi-finished product of mRNA-LNP preparations. The positioning sensor for detecting the position of the raw material or semi-finished product is installed on one side of the encapsulation module. The positioning sensor is used to detect the position of the raw material or semi-finished product and transmit the position information to the control system module. The speed controller adjusts the conveying speed according to the instructions of the control system module to ensure that the raw materials or semi-finished products of mRNA-LNP preparations on each track accurately reach the encapsulation station of the aseptic operation cabin. The multi-track conveying system is similar to multiple independent conveyor belts, and each conveyor belt is responsible for transporting a specific type of raw material or semi-finished product. The positioning sensor can be a photoelectric sensor or other types of sensors, used to detect whether the raw material or semi-finished product reaches the designated position. The speed controller controls the running speed of the conveying track by adjusting the motor speed or other driving methods;

[0029] It realizes the automated conveying of raw materials or semi-finished products, improves production efficiency, reduces the pollution risk brought by manual operations, ensures that the raw materials can accurately and timely reach the encapsulation station, and guarantees the continuity and stability of production. The automated conveying module conveys the raw materials to the encapsulation station in an aseptic environment, ensuring that the raw materials are not contaminated during the conveying process.

[0030] The encapsulation module is installed on the encapsulation station in the aseptic operation chamber to perform encapsulation operations on the raw materials or semi-finished products of the mRNA-LNP preparation sent by the automated conveying module. The encapsulation module includes an aseptic connection component and an encapsulation unit. The aseptic connection component is installed above the interior of the aseptic operation chamber, and the encapsulation unit is installed on the encapsulation station in the aseptic operation chamber. The encapsulation unit and the aseptic connection component perform injection encapsulation operations on the raw materials or semi-finished products of the mRNA-LNP preparation. The aseptic connection component includes an aseptic docking head and a sealing mechanism. The encapsulation unit includes a high-precision injection pump and a multi-chamber encapsulation mold. The high-precision injection pump is aseptically docked with the multi-chamber encapsulation mold through the aseptic docking head and the sealing mechanism to accurately inject the mRNA-LNP preparation into the multi-chamber encapsulation mold and perform encapsulation processing;

[0031] It should be noted that the multi-chamber encapsulation mold is provided with multiple encapsulation chambers to simultaneously complete the encapsulation operations of multiple mRNA-LNP preparations. The aseptic docking head and the sealing mechanism can connect the preparation container with the encapsulation unit without destroying the aseptic environment, preventing external microorganisms from entering. The high-precision injection pump can accurately control the injection dose to ensure the accurate preparation dose in each encapsulation chamber. The multi-chamber encapsulation mold allows simultaneous encapsulation of multiple preparations, improving production efficiency.

[0032] The quality inspection module is used to perform quality inspection on the encapsulated preparation. The quality inspection module is set in the aseptic operation chamber and is located behind the encapsulation module. The quality inspection module includes an appearance inspection unit, a sealing inspection unit, and a content inspection unit. The appearance inspection unit checks the appearance of the mRNA-LNP preparation through a high-resolution camera, and the inspection result is transmitted to the control system module.

[0033] The sealing inspection unit detects the sealing performance of the encapsulation container through pressure changes. The content inspection unit uses fluorescence spectroscopy analysis technology to detect the mRNA content in the preparation. After the encapsulation module completes the encapsulation operation, the quality inspection module can timely feedback the inspection result to the control system module. The control system module adjusts the operating parameters of the encapsulation module according to the feedback result. The quality inspection module performs multi-dimensional inspection on the preparation, and the inspection result is feedback to the control system module. The control system module adjusts the encapsulation parameters according to the result to form a closed-loop control;

[0034] The high-resolution camera can capture the appearance details of the preparation, such as whether there are cracks, foreign objects, etc. The sealing performance is detected by filling a certain pressure of gas into the encapsulation container and then monitoring the pressure change. If the pressure drops, it indicates poor sealing performance. Fluorescence spectroscopy analysis technology can quickly and accurately detect the mRNA content in the preparation to ensure that it meets the quality standards. Performing multi-dimensional quality inspection on the encapsulated preparation ensures that the product quality meets the standards, timely discovers and corrects problems in the production process, and improves production efficiency and product quality.

[0035] The control system module is used to control the operation of each module and monitor the parameters of the entire encapsulation process. The control system module is electrically connected to the automated conveying module, the encapsulation module, and the quality inspection module through a data bus. The control system module includes a data processing unit, a processing unit, and an execution unit. The data processing unit collects parameters during the encapsulation process, such as temperature, humidity, pressure, injection dose, etc. The processing unit receives the collected data sent by the data processing unit for analysis and processing to determine whether it meets the preset standards. The execution unit controls the operation of the system according to the control instructions sent by the processing unit, such as adjusting the conveying speed, injection dose, pausing production, etc., to uniformly control and manage the operation of the entire encapsulation system, ensure the coordinated work of each module, and monitor and adjust the parameters in the production process in real time to ensure the smooth progress of production and the stability of product quality.

[0036] Furthermore, in order to prevent the waste liquid generated during production from affecting the environment, the system is also equipped with a waste liquid treatment module. The waste liquid treatment module includes a filtration unit, an adsorption unit, and an inactivation unit. The filtration unit usually contains filter membranes or filters with different pore sizes to remove particulate matter in the waste liquid. The adsorption unit is used to adsorb organic substances in the waste liquid. The adsorption material in the adsorption unit has a large number of micropores and a large surface area, which can adsorb organic molecule. The inactivation unit is used to inactivate the bioactive substances in the waste liquid. The inactivation unit selects a suitable inactivation method according to the characteristics of the waste liquid and the type of bioactive substances to ensure that the waste liquid discharge meets the environmental protection standards. The filtration unit, the adsorption unit, and the inactivation unit are connected in sequence through pipelines. The waste liquid is discharged after passing through the filtration unit, the adsorption unit, and the inactivation unit in sequence to treat the waste liquid generated during the encapsulation process, remove the pollutants and bioactive substances in it, prevent environmental pollution, and at the same time avoid the pollution of the aseptic operation cabin by the microorganisms in the waste liquid.

[0037] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of the present invention.
