Description

Technical Field

[0001] This invention relates to the field of medical devices and intelligent control technology, and in particular to an intelligent pediatric oral medication dispensing and administration system based on the child's weight. Background Technology

[0002] The accuracy and safety of pediatric medication dosages is a global medical challenge. Children are in a stage of rapid growth and development, with rapid changes in liver and kidney function, weight, and body surface area, necessitating individualized dosage calculations that typically consider multiple parameters such as weight and age. Currently, in homes and primary healthcare institutions, oral medication dosages are generally administered manually, which has the following significant drawbacks: Crude dosage calculations: Most parents and even medical staff simply calculate based on the weight per kilogram on the drug instructions, ignoring key factors such as age, body surface area, and specific pharmacokinetics of the drug, and are prone to calculation errors.

[0003] Low accuracy in dispensing medication: Breaking tablets by hand or using a simple cutter to dispense medication results in huge errors, especially for small doses of medication that require 1 / 4 or 1 / 8 of a tablet. This cannot guarantee dosage accuracy, affecting efficacy and even leading to poisoning.

[0004] Risk of dosage form misuse: Ordinary users cannot distinguish between indivisible dosage forms such as extended-release tablets, enteric-coated tablets, and capsules. Incorrectly splitting these dosage forms can damage the drug structure, leading to sudden release or drug inactivation, and causing serious adverse reactions.

[0005] Hygiene and pollution risks: The dispensing device is difficult to clean, and residual powder can easily lead to cross-contamination between different medicines and the growth of microorganisms.

[0006] Lack of traceability and supervision: The entire medication process is not recorded, and once a medication error occurs, it is impossible to trace the cause and the responsible party.

[0007] Existing automated medication dispensing equipment is limited in function, capable only of simple mechanical division. It lacks the ability to identify medications, determine dosage forms, and self-verify dispensing accuracy, thus failing to fundamentally address the aforementioned safety concerns. Therefore, there is an urgent need for a pediatric medication solution that enables intelligent, precise, and aseptic management throughout the entire process. Summary of the Invention

[0008] To overcome existing problems, this application provides an intelligent pediatric oral medication dispensing and administration system based on the child's weight.

When the dosage calculated by the central control module exceeds the safety threshold determined based on drug information and individual patient information, a medication safety warning message is pushed to the user terminal or system interface. The central control module is configured to receive individual patient information and drug identification results, and generate comprehensive instructions based on the built-in medication decision algorithm, including personalized dosage and dosage form separability judgment.

[0010] Preferably, the intelligent drug identification module includes at least one of an image recognition unit and a near-infrared spectroscopy analysis unit. The medication decision algorithm accesses a local or cloud-based drug information database, compares the identification results with the database information, and completes the dosage form separability judgment and dosage calculation rule invocation.

[0011] Preferably, the precision dispensing module includes a dispensing execution unit and a weight sensing unit; The central control module is further configured as follows: After the dispensing execution unit performs its operation, it receives real-time weight feedback data from the weight sensing unit and compares this data with the theoretical weight calculated based on the personalized dosing dosage. The dispensing accuracy is then verified or the dispensing operation is adjusted in a closed-loop control manner.

[0012] Preferably, the aseptic medication delivery module adopts a modular and detachable design and includes disposable aseptic accessories for receiving and administering medication, which are sealed in packaging before each use.

[0013] Preferably, the central control module is further configured to: when the drug intelligent identification module identifies the drug dosage form as an indivisible dosage form, generate a prohibition instruction for dispensing and lock the precision dispensing module, and at the same time issue a visual or auditory alarm through the cloud platform service module or local interface to remind the user that the drug cannot be divided for consumption.

[0014] Includes the following steps: Step 1: Obtain individual information for the child, including at least weight and age; Step 2: Intelligently identify the drugs to be repackaged and obtain their identity and dosage form information; Among them, at least one of the techniques of image recognition and near-infrared spectroscopy analysis is employed; The step of generating a comprehensive instruction that includes personalized dosage and dosage form separability determination includes: Invoke the dosage calculation rules based on multidimensional parameters of weight and age, and perform a physical and pharmacological separability judgment of the dosage form; Step 3: Based on individual and drug information, multi-source data is fused through a medication decision-making algorithm to generate a comprehensive instruction that includes personalized dosage and dosage form separability judgment; Step 4: If the dosage form can be separated, initiate the precision dispensing operation; It also includes a precision verification step: The actual weight of the medicine after dispensing is obtained by a weighing sensor, and the weight data is fed back to the decision-making process and compared with the theoretically calculated weight. If the error exceeds the allowable range, the medicine will be re-dispensed or an alarm will be triggered. Step 5: Dispense the pre-packaged medication using aseptic techniques.

[0022] By integrating multi-source information with drug identification data, a leap from experience-based estimation to personalized intelligent decision-making has been achieved. This fundamentally avoids the two core safety hazards of a single dosage calculation model and incorrect dosage form segmentation. Through closed-loop quality control of calculation, execution, weighing, and feedback, the drug dispensing process has been upgraded from open-loop execution to verifiable precision manufacturing, ensuring the extreme reliability of small-dose administration.

[0023] The modular design and disposable accessories bring hospital-grade aseptic operation into daily life, completely solving the problems of cross-contamination and cleaning. It expands the function of a single device into a fully traceable medication safety management platform, providing supervision and protection for home users through electronic logs and safety alerts.

[0024] The technical solution in this application is to solve the above problems, and the overall approach is as follows: Example

[0025] This embodiment presents an intelligent pediatric oral medication dispensing and administration system based on the child's weight, such as... Figure 1 As shown, it includes: The central control module, which embeds a medication decision-making algorithm, is responsible for coordinating the work of each module and making the final decision based on the received information. Furthermore, the central control module can integrate and process the individual information of the child and the drug identification results to generate a comprehensive instruction that includes both personalized dosage and dosage form separability judgment. Then, when the dosage form is separable, the precision dispensing module executes the dispensing according to the dosage instruction and uses the weight sensing unit to form a closed-loop control to ensure accuracy.

[0026] A multi-source information input module is used to receive individual patient information, including at least weight and age; By integrating multi-source information with drug identification data, a leap from experience-based estimation to individualized intelligent decision-making has been achieved, fundamentally avoiding the two core safety hazards of a single dosage calculation model and incorrect dosage form segmentation. Through closed-loop quality control of calculation, execution, weighing, and feedback, the drug dispensing process has been upgraded from open-loop execution to verifiable precision manufacturing, ensuring the extreme reliability of small-dose administration. The multi-source information input module includes: The drug locking unit is used to identify a target drug in a drug information database. Users can locate the target drug by scanning the drug barcode or manually entering the drug name, and the unit will then query and identify the target drug in a local or cloud-based drug information database. The attribute acquisition unit reads the dosage form, separability rules, and dosage calculation rules of the drug from the drug information database. Specifically, it reads the key attributes of the locked drug from the drug information database, including dosage form, physical separability rules, pharmacological separability rules, and dosage calculation rules for the drug. And, a dosage form safety judgment unit, which includes: The dynamic selection dosage calculation model subunit is used to intelligently select the optimal model based on drug rules and input patient information; The safety verification subunit compares the calculated dose with the safety threshold in the drug information database, and triggers a warning if the limit is exceeded. Furthermore, the multi-source information input module is used to receive individual information about the child, including at least weight and age. This module further includes: Drug locking unit: Users can scan the drug barcode or manually enter the drug name, and this unit will query and identify the target drug in a local or cloud-based drug information database.

[0027] Attribute acquisition unit: Reads key attributes of locked drugs from the drug information database, including dosage form, physical separability rules, pharmacological separability rules, and dosage calculation rules for the drug.

[0028] Dosage Form Safety Judgment Unit: Dynamically select the dosage calculation model subunit: Based on the drug dosage calculation rules and the input information such as the child's weight and age, intelligently select the most suitable mathematical model for calculation. For drugs calculated by weight, the dosage = weight × unit weight dose is directly used; for complex cases, a composite model based on age and weight may be used.

[0029] Safety verification subunit: The calculated theoretical dosage is compared with the preset minimum and maximum safe dosages for a specific age and weight range in the drug information database. If the calculation result exceeds the safety threshold, a warning is triggered immediately.

[0030] The intelligent drug identification module is used to identify the identity and dosage form information of the drugs to be packaged and output the drug identification results. The intelligent drug identification module includes at least one of an image recognition unit and a near-infrared spectroscopy analysis unit. The medication decision algorithm accesses a local or cloud-based drug information database, compares the identification results with the database information, and completes the determination of dosage form separability and the invocation of dosage calculation rules. Furthermore, the intelligent drug identification module serves as a redundancy check and security safeguard, and includes an image recognition unit and a near-infrared spectroscopy analysis unit.

[0031] Operation scenario: When the user places the medicine into the designated area, the module is activated. The image recognition unit captures the appearance, shape, color, and markings of the medicine, while the near-infrared spectroscopy analysis unit analyzes the composition spectrum of the medicine.

[0032] The identification result is cross-validated with the drug information locked in the multi-source information input module. If there is a discrepancy, the system will issue an alarm and require manual confirmation. At the same time, the identification result is directly used for subsequent dosage form separability determination.

[0033] The precision dispensing module is used to perform dispensing operations corresponding to the personalized dosage when the central control module determines that the dosage form can be dispensed. The precision dispensing module includes a dispensing execution unit and a weight sensing unit. Furthermore, after the central control module determines that the dosage form is divisible, the precision dispensing module performs the dispensing operation, which includes: Dispensing unit: Depending on the dosage form, a high-precision cutter can be used for tablets, while a quantitative powder dispenser can be used for capsules or powders.

[0034] Weight sensing unit: Employs a high-precision weighing sensor to weigh medicines before and after dispensing operations.

[0035] In addition, there is a sterile drug delivery module, which is used to output the dispensed drugs in a sterile manner; The aseptic medication delivery module features a modular and detachable design and includes disposable aseptic accessories for receiving and administering medications, which are sealed in packaging before each use. The accessories in the aseptic medication delivery module are in an independent sealed package before installation to ensure sterility for single use. The dispensed medication is directly placed into the aseptic accessory for the child to take. It also includes a cloud platform service module that communicates with the central control module; The cloud platform service module is used for: Storing and updating drug information database; Record and store an operation log for each medication dispensing operation. The operation log should include at least the medication information, the child's individual information, the calculated dosage, the actual amount of medication dispensed, and the operation timestamp. Furthermore, the cloud platform service module and the central control module are connected via encrypted network communication. This module is used for: Store and regularly update the drug information database to ensure that dosage rules and safety information are up-to-date.

[0036] Record and store an operation log for each medication dispensing operation. The log should include at least the following: medication name, batch number, child's weight and age, calculated dosage, actual dispensing weight, operation timestamp, and operator ID.

[0037] When the calculated dosage by the central control module exceeds the safety threshold, or when the intelligent drug identification module detects a mismatch, the cloud platform can push real-time medication safety warnings to the bound user terminals or system operation interfaces. These warnings can also be sent simultaneously to pre-defined medical personnel. When the dosage calculated by the central control module exceeds the safety threshold determined based on drug information and individual patient information, a medication safety warning message is pushed to the user terminal or system interface. The central control module is configured to receive individual patient information and drug identification results, and generate comprehensive instructions based on the built-in medication decision algorithm, including personalized dosage and dosage form separability judgment.

[0038] The central control module is further configured as follows: After the dispensing execution unit performs its operation, it receives real-time weight feedback data from the weight sensing unit and compares this data with the theoretical weight calculated based on the personalized dosing dosage. The dispensing accuracy is verified or the dispensing operation is adjusted in a closed-loop control manner.

[0039] The central control module is further configured to: when the drug intelligent identification module identifies the drug dosage form as indivisible, generate a prohibition instruction for dispensing and lock the precision dispensing module, and at the same time issue a visual or auditory alarm through the cloud platform service module or local interface to remind the user that the drug cannot be divided.

[0040] Furthermore, for indivisible dosage forms: when the intelligent drug identification module recognizes that the drug dosage form is an indivisible dosage form such as sustained-release tablets or enteric-coated capsules, the central control module immediately generates a dispensing prohibition command and locks the mechanical structure of the precision dispensing module via software lock to prevent accidental operation. Simultaneously, a flashing red alarm and a buzzer sound are emitted through the system interface.

[0041] Closed-loop medication dispensing accuracy control: After the dispensing execution unit operates, the central control module receives real-time weight feedback data from the weight sensor unit. This actual weight is compared with the theoretical weight calculated based on the personalized dosage and the unit weight of the medication. If the error is within a preset range, the dispensing is considered successful; if it exceeds the tolerance, the dispensing execution unit is controlled to fine-tune and supplement or remove excess medication until the weight meets the standard. This process forms a closed-loop control, ensuring medication dispensing accuracy.

[0042] Includes the following steps: Step 1: Obtain individual information of the child, including at least weight and age. The system obtains the child's individual information, including at least weight and age, through a multi-source information input module. Step 2: Intelligent identification of the drug to be packaged, obtaining its identity and dosage form information. The system uses a drug intelligent identification module to identify the drug to be packaged. Through image recognition and near-infrared spectroscopy analysis, the system identifies the name of the drug and generates the drug identification result. Among them, at least one of the techniques of image recognition and near-infrared spectroscopy analysis is employed; The steps for generating a comprehensive instruction that includes personalized dosing dosage and dosage form separability assessment include: Invoke the dosage calculation rules based on multidimensional parameters of weight and age, and perform a physical and pharmacological separability judgment of the dosage form; Step 3: Based on individual and drug information, multi-source data is fused through a medication decision-making algorithm to generate a comprehensive instruction that includes personalized dosage and dosage form separability judgment; Step 4: If the dosage form can be dispensed, start the precision dispensing operation. After precision dispensing is completed, the system prompts the user to take the disposable sterile feeding or medicine cup pre-installed in the sterile feeding module. The dispensed medicine is automatically or manually injected into the sterile accessory to complete the sterile output and prepare for feeding. It also includes a precision verification step: The actual weight of the dispensed medicine is obtained by a weighing sensor and fed back to the decision-making process. This weight is compared with the theoretically calculated weight. If the error exceeds the allowable range, a re-dispensing or alarm is triggered. Specifically, before and after dispensing, the weight sensor unit weighs the container holding the medicine, calculates the actual weight and volume of the dispensed medicine based on the weight difference, and feeds this data back to the central control module. The central control module compares the actual dispensing amount with the theoretically calculated amount. If the error is within the allowable range, the process proceeds to the next step; if it exceeds the tolerance, the system indicates abnormal dispensing accuracy, requiring a re-operation or automatic fine-tuning. Step 5: Dispense the pre-packaged medication using aseptic techniques.

[0043] It also includes safety and traceability steps: the entire process data of this medication dispensing operation is encrypted and uploaded to the cloud to generate an unalterable electronic traceability record. If the calculated dosage exceeds the safety threshold, the central control module will immediately interrupt the process and push a warning to the user's mobile APP and system interface through the cloud platform service module. If a safety risk is identified during the dosage calculation or dosage form determination process, the process will be interrupted and an alert will be issued to the user and relevant medical professionals.

[0044] Further, in the information acquisition step, the system obtains the child's individual information through a multi-source information input module, including at least weight and age.

[0045] The intelligent drug identification process involves the system using an intelligent drug identification module to identify the drugs to be packaged. Through image recognition and near-infrared spectral analysis, the system identifies the name of the drug and generates a drug identification result.

[0046] In the decision-making and instruction generation process, the central control module receives individual patient information and drug identification results.

[0047] Drug locking and attribute acquisition: The central control module calls the multi-source information input module to lock the name in the drug information database and acquire its attributes based on the identified drug name.

[0048] Dosage Calculation and Safety Verification: The dosage form safety assessment unit is activated. The dynamically selected dosage calculation model subunit calculates according to the rules: taking the median value of 30mg / kg / day, the total daily dose = 15kg × 30mg / kg = 450mg. Divided into three doses, the single dose = 450mg / 3 = 150mg. The safety verification subunit queries the single-dose safety threshold for this drug; 150mg is within the safe range, and the verification passes.

[0049] Dosage form separability determination: Based on the acquired dosage form and separability rules, the central control module determines that the dry suspension can be dispensed into liquid volumes after being brewed from the whole package, therefore the dosage form is separable.

[0050] Finally, the central control module generates a comprehensive instruction: allow dispensing of the drug, with a target single dose of 150mg of active ingredient.

[0051] Precise drug dispensing and accuracy verification steps.

[0052] If the dosage form can be separated, the precision dispensing module is activated. The user dissolves the entire package of dry suspension in a measured amount of warm water, and the dispensing unit extracts the corresponding liquid according to the instructions.

[0053] Accuracy Verification: Before and after dispensing, the weight sensor unit weighs the container holding the medicine liquid, calculates the actual weight and volume of the dispensed medicine liquid based on the weight difference, and feeds this information back to the central control module. The central control module compares the actual dispensing amount with the theoretically calculated amount. If the error is within the allowable range, proceed to the next step; if it exceeds the tolerance, the system prompts an abnormal dispensing accuracy, requesting a repeat operation or automatic fine-tuning.

[0054] After the aseptic output process is completed and the precise dispensing is finished, the system prompts the user to take the disposable aseptic feeding cup or medicine cup that has been pre-installed in the aseptic feeding module. The dispensed medicine is automatically or manually injected into the aseptic accessory to complete the aseptic output and prepare for feeding.

[0055] In the safety and traceability process, if the calculated dose exceeds the safety threshold, the central control module will immediately interrupt the process and push an alert to the user's mobile APP and system interface through the cloud platform service module.

[0056] After the entire medication dispensing process was completed, the key data from this operation was encrypted, packaged, and uploaded to the cloud platform service module.

[0057] The cloud platform generates an immutable electronic traceability record containing a unique serial number, timestamp, and hash value, which is stored in a blockchain or secure database for subsequent auditing, querying, or medical analysis.

[0058] Through the above-mentioned system and method, this invention realizes full-process automation, personalization and intelligence from drug identification, dosage calculation, dosage form judgment, precise dispensing to aseptic feeding, which significantly improves the safety, accuracy and convenience of pediatric medication.

[0059] Workflow Information input: Users input information such as the child's weight and age via a touchscreen.

[0060] Drug identification: Place the drug in the identification area, and the system will automatically identify the drug name, specifications and dosage form through image and / or spectral technology.

[0061] Intelligent decision-making: The central controller calls the dosage rules of the drug in the cloud, calculates the accurate dosage by combining the child's information, and determines whether the dosage form can be separated.

[0062] If the medication cannot be dispensed: the system locks the dispensing function, issues an audible and visual alarm, and terminates the process; if the medication can be dispensed: the system generates a dispensing instruction containing the target dose.

[0063] Precision dispensing and calibration: The dispensing actuator starts dispensing the medicine. After dispensing, the weight sensor weighs the dispensed tablets and powders. The central controller compares the measured weight with the theoretical weight. If the error is within the allowable range, the process continues. If the error exceeds the limit, the system alarms or automatically performs fine-tuning compensation.

[0064] Aseptic medication administration: The system prompts the user to install a disposable medication tube or medicine cup. The pre-packaged medication is placed directly into the tube, and the user can safely administer it after removing the tube.

[0065] Cloud-based recording and traceability: All key data from the above steps are encrypted and uploaded to the cloud platform, generating tamper-proof electronic records.

[0066] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
