[0006] A supplies outbound management module, when executing an outbound operation, the supplies outbound management module will record the information currently acquired by the mobile scanning terminal and the operations performed;

[0007] The information of the supplies storage management module is interoperable with the hospital's patient data system and stored in the same database. When the supplies storage management module generates a record, a record is inserted into the current database synchronously to map the ID of the RFID tag or the barcode or the QR code with the patient data system:

[0008] INSERT INTO rfid_mapping(rfid_id,hospital_id)VALUES('RFID123456','ID78910').

[0009] Preferably, it also includes:

[0010] The intelligent replenishment control module generates a replenishment list based on the current inventory situation, and predicts demand in the future based on historical supplies consumption data. It revises the replenishment list based on the prediction results and gives the final replenishment order.

[0011] The visual management module provides real-time visual display of incoming, outgoing and inventory data, making it easier for operators to follow up on current data in real time;

[0027] GeneralMedical supplies refer to medicines, medical devices and medical auxiliary supplies used to treat human diseases. However, in this application document, it mainly refers to portable and removable supplies. Generally speaking, taking medicines as an example, after the purchase and acceptance of medicines, the following will be carried out:

[0028] Drug Storage: Drugs are properly stored in the drug warehouse or pharmacy to ensure their safety and effectiveness.

[0029] Clinical use: Doctors prescribe drugs based on patient needs, and pharmacies distribute drugs based on the prescriptions. The process from drug delivery from the pharmacy to patient use may involve drug returns or drug recycling, which will be returned to the warehouse after confirmation by the pharmacist and reported to the procurement center and the financial center for record.

[0030] Consumption reconciliation: After the use of drugs, consumption reconciliation is required, which can be daily reconciliation or monthly reconciliation. Daily reconciliation is to check the consumption and return documents every day, while monthly reconciliation is done once a month.

[0031] In particular, some medicines need to be dispensed through a distribution center, and the distribution center needs to reconcile and match data with the pharmacy. The distribution center also needs to match data with the inpatient system.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] Hospitals generally have a hospital management information system HIS, which is the core component of hospital information construction. In terms of current system architecture design, HIS systems usually adopt a layered architecture, including presentation layer, business logic layer and data access layer. The presentation layer is responsible for the display of the user interface, the business logic layer handles various business logics, and the data access layer is responsible for interaction with the database. This layered architecture design can achieve decoupling between layers and improve the flexibility and maintainability of the system. The architecture development of the new generation of HIS tends to be both integrated and open, and intelligent and extensible. This includes building an integrated HIS and electronic medical record system to achieve functional integration and data integration, as well as improve the openness and extensibility of the system. That is, HIS generally integrates an electronic medical record system. Taking the distribution center as an example, the current distribution center is manually distributed, and the liquid preparation is done manually and delivered to the ward. The distribution center spends a lot of time on various checks. To this end, our company has developed a control system and corresponding methods for the addition of supplies to the warehouse, the outbound delivery of supplies, and the automatic replenishment of supplies in the medical field.

[0034] Example 1

[0035] This embodiment provides a control system for adding supplies to a warehouse, taking supplies out of a warehouse, and automatically replenishing supplies in the medical field, specifically including the following modules:

[0036] Supplies warehousing management module:

[0037] This module includes two core components: the identification generation unit and the data collection terminal. The identification generation unit is responsible for automatically generating unique identification such as RFID tags, barcodes or QR codes for newly stored medical supplies. The data collection terminal is used by staff to record detailed information such as storage time, quantity, batch, expiration date, etc. by scanning the identification, and upload the data to the backend system.

[0038] Taking the distribution liquid and medicine of the distribution center as an example, in general, the electronic medical record will follow the "Health Information Data Meta Directory" standard to set the data metadata, and the entire background will receive the electronic medical record information that needs to be dispensed. This electronic medical record information is in the form of electronic medical record data tables that can store information in a structured form, which is convenient for data retrieval and analysis. For example, data can be stored in HTML5, JSON or XML format. For example, the electronic medical record contains patient ID information, patient location information (how many rooms, how many beds, etc.), and what liquids and medicines are included in the dispensed medicines. An automatic verification module is set in the user warehousing management module. In addition, the system automatically generates a record when an electronic medical record is received, and the record ID corresponds one-to-one with the electronic medical record ID hospital patient identity code.

[0039] Considering that the liquid preparation of patients in electronic medical records ID hospitals can have multiple parallel processing steps, for this reason, in the medical supplies management system of the distribution center, a processing node is set for each parallel liquid preparation and mapped to the hash value space, thereby forming a hash ring: the consistent hashing algorithm maps the entire hash value space into a virtual ring, and the value range of the entire hash space is 2-3000. This ring is continuous, starting from 0, ending at 3000, and then returning to 0, forming a closed loop. The data request sent by the processing process involved in each liquid preparation process is calculated using the hash algorithm to calculate the corresponding hash value, and then the calculated hash value is mapped to the hash ring. The data request will be assigned to the nearest processing node according to its hash value. If the hash value happens to be the same as the hash value of a processing node, then the data request will be assigned to the processing node. If it is different, the data request will be assigned to the next processing node in the clockwise direction. In this way, every process data involved in liquid preparation can be stored and the data consistency can be maintained.

[0040] Of course, you can also use components such as Canal to monitor MySQL data changes in real time, connect with Canal Client through a unified "message distribution service", distribute messages to different MQ clusters in a unified format, and consume messages through a unified "message consumption service" and call back the business interface to achieve data synchronization.

[0041] In this module, an important technical point needs to be explained: that is, to establish a mapping connection between the unique identifiers such as RFID tags, barcodes or QR codes in the supplies storage management module and the hospital patient identity code. The process of establishing the mapping is as follows:

[0042] The first stage is data preparation

[0043] Collect information related to the hospital identification code: Ensure the uniqueness and accuracy of the hospital identification code, which may contain key data such as the patient's basic information and medical record number.

[0044] Prepare RFID tags: Each RFID tag has its own unique identification number (UID).

[0045] Next is the mapping phase.

[0046] Select database: You can use the hospital's existing information management system database or establish a database specifically for storing mapping relationships.

[0047] If using an existing system, its compatibility and scalability need to be evaluated.

[0048] When creating a new database, you need to design a reasonable table structure, such as including the RFID tag UID field and the hospital identification code field.

[0049] Then comes data entry:

[0050] Manual entry: For small amounts of data, the UID of the RFID tag and the corresponding hospital identification code can be manually entered into the database one by one.

[0051] Automated data entry: When the amount of data is large, automated equipment and software can be used to scan RFID tags and read hospital identity code information, automatically linking the two and storing them in the database.

[0052] Establishing indexes: To improve data retrieval efficiency, indexes are established in the database for the RFID tag UID and hospital identity code fields.

[0053] Finally, the verification and maintenance phase

[0054] Verify the mapping relationship:

[0055] A portion of the mapping data was randomly selected for verification to check whether the RFID tag and the hospital identification code corresponded correctly.

[0056] The accuracy of the mapping can be tested by simulating actual usage scenarios, such as registration, medical consultation, and examination in a hospital.

[0057] Maintain the mapping relationship:

[0058] When new patient information is entered or the RFID tag is replaced, the mapping relationship in the database is updated in a timely manner.

[0059] Regularly check the completeness and accuracy of data and deal with any problems found in a timely manner.

[0060] In the above process, it is also necessary to ensure the security of the mapping relationship between the RFID tag and the hospital identity code. In terms of data storage, the mapping relationship data stored in the database can be encrypted, including the RFID tag information and the hospital identity code. For example, symmetric encryption algorithms (such as AES) or asymmetric encryption algorithms (such as RSA) can be used. Access control: Set strict database access rights so that only authorized personnel can read and modify the mapping relationship data. Different permission levels are assigned according to the responsibilities of different personnel, such as doctors, nurses, administrators, etc.

[0061] In terms of data transmission, secure transmission protocols can be used: when transmitting mapping relationship data, use secure transmission protocols, such as HTTPS instead of HTTP, to ensure the security of data transmission in the network and prevent data from being stolen or tampered with. Data integrity verification: Use data verification technology, such as hash functions (such as SHA-256) to perform integrity verification on the transmitted data, so that the receiver can verify whether the data has been tampered with during the transmission process.

[0062] At the tag level, tag encryption can be used: encrypting the RFID tag itself so that the information in the tag can only be read through a specific decryption algorithm, increasing the difficulty of illegal reading of tag data. Anti-cloning technology: using RFID tags with anti-cloning functions, such as using physical unclonable function (PUF) technology, so that each tag has unique and non-copyable physical characteristics.

[0063] In terms of system management, security audit can be used: establish a security audit mechanism to record operations involving mapping relationship data, including information such as the operator, operation time, and operation content. This allows for tracing and investigation when security issues arise. Regular security assessment: regularly assess the security of the entire system, including software, hardware, and network, to promptly discover and repair potential security vulnerabilities.

[0064] Supplies outbound management module:

[0065] The module automatically obtains the specific storage location information of medical supplies and displays navigation tips for quick access to operators through mobile terminals. The mobile terminal will capture the information of supplies when they are shipped out in real time, including type, quantity, etc., and synchronize the shipping records to the backend system.

[0066] Intelligent replenishment control module:

[0067] This module consists of two parts: the inventory record submodule and the data analysis submodule. The inventory record submodule will track the inventory quantity and historical outbound status of various medical supplies in real time. The data analysis submodule will perform statistical analysis on the historical outbound data and use time series prediction, machine learning and other methods to predict the demand in the future. The system automatically generates the best replenishment plan and order based on the current inventory status and predicted demand.

[0068] Visual management module:

[0069] This module displays the real-time operation of key indicators such as inventory, warehousing, and replenishment through a visual dashboard. The system also monitors and issues prompts including low inventory and expiration warnings in real time based on predefined exception rules. Managers can export various custom reports, such as category analysis and top product reports, to support further in-depth analysis.

[0070] Traceability query module:

[0071] This module provides full life cycle traceability based on single product identification codes and batch information. Single product traceability can query the specific operation records of a medical supply at each node, including warehousing, outbound delivery, replenishment, etc. Batch traceability can view the relevant detailed flow information for a batch of supplies.

[0072] In this embodiment, the supplies storage management module is implemented through RFID technology, barcode / two-dimensional code (QR code) technology and data collection terminal.

[0073] RFID technology uses high-frequency or ultra-high-frequency RFID technology to generate a unique label for each medical supply. RFID tags contain product information, such as key attributes such as item code, batch number, and expiration date. Equipped with RFID reading and writing equipment, including fixed RFID access control, handheld RFID scanners, etc., to achieve automatic identification and data collection of medical supplies. RFID reading and writing equipment transmits the collected data to the backend system database in real time through wireless communication protocols (such as WiFi, 4G, etc.).

[0074] For medical supplies that cannot be attached with RFID tags, barcodes or QR codes are used for identification. Use a professional printer to print a unique barcode or QR code on the medical supply packaging. Equipped with a handheld barcode / QR code scanner, the product information is automatically obtained and uploaded to the system after scanning the barcode / QR code. The barcode / QR code data is also transmitted to the background database through the wireless network and integrated with the RFID data for management.

[0075] The data collection terminal uses mobile devices such as smartphones and tablets as data collection terminals, equipped with RFID reading and writing modules and barcode / QR code scanners. The terminal device uses Android or iOS operating system and installs a dedicated supplies management APP. The APP can collect various attribute information of incoming / outgoing goods in real time and synchronize it to the background system through 3G / 4G / WiFi network. The terminal device can also interact with supporting equipment such as smart shelves and indicator lights through technologies such as Bluetooth and NFC to guide staff to quickly locate the location of goods.

[0076] The system uses distributed database technology to achieve efficient storage and query of massive RFID / barcode data. It applies big data analysis technology to conduct in-depth mining of the collected data on the in and out of the warehouse and discover hidden business rules. The system can also combine external data sources (such as ERP, OA and other systems) for data fusion analysis to enhance decision support capabilities.

[0077] When implementing intelligent replenishment, the demand forecasting model is first established. The system background will collect historical outbound data of various medical supplies, including quantity, time and other information. Data mining technologies such as time series analysis and machine learning are used to establish demand forecasting models for different supplies. The forecasting model will consider the impact of seasonal factors, holiday factors and other factors on the demand for supplies to improve the accuracy of the forecast. The system will automatically run the forecasting model regularly (such as weekly) to generate a forecast of supply demand within a certain period of time in the future (such as one week). In order to determine the inventory optimization algorithm, the system monitors the current inventory level of various medical supplies in real time and compares and analyzes it with the predicted demand. Applying intelligent optimization algorithms, according to factors such as supply characteristics, procurement cycle, safety stock, etc., an economical and efficient replenishment plan is automatically generated. The optimization algorithm will consider a variety of constraints, such as budget constraints, supplier delivery dates, etc., and output the optimal replenishment quantity and time. The system will also implement a special priority replenishment strategy for expiring products to reduce the risk of expiration. Then, automatic ordering and execution are carried out. According to the optimized replenishment plan, the system automatically generates a purchase order and sends it to the corresponding supplier. The order contains key information such as product code, quantity, delivery time, etc., and the supplier can directly connect and execute. The system will track the execution of orders in real time. Once a delay or other abnormal situation is found, it will issue a warning and adjust the replenishment plan in time. After the supplier completes the delivery, the system will automatically update the inventory data to ensure the timeliness and accuracy of the information. Finally, the intelligent scheduling and distribution system can intelligently schedule and distribute replenishment goods based on the actual usage of each department of the hospital. The path optimization algorithm is used, combined with the transportation resources within the hospital, to plan the optimal delivery route and time. During the distribution process, the system will monitor the location and status of the transport vehicle in real time to ensure that the goods arrive at the destination on time. For urgently needed supplies, the system can also command manual rapid dispatch to ensure that the department gets the required supplies in time.

[0078] Visual management includes:

[0079] (1) Data Visualization

[0080] The system background collects and integrates comprehensive data on inventory, warehousing, replenishment, etc. of various medical supplies. Using business intelligence (BI) technology, these key business data are visualized on the management dashboard on the Web. The dashboard displays indicators such as inventory levels, usage trends, replenishment status, etc. of various medical consumables in real time in the form of charts and meters. Managers can flexibly switch data views of different dimensions through interactive operations to gain in-depth insights into business operations.

[0081] (2) Early warning monitoring

[0082] The system will automatically monitor the inventory dynamics of various medical supplies according to the preset warning rules. Once abnormal situations such as low inventory and expiration warning are found, the system will actively push warning information through emails, text messages, etc. Managers can view the detailed information of various warning events in real time on the dashboard and take corresponding measures.

[0083] (3) Customized reports

[0084] The system provides flexible report customization functions, and managers can design various inventory analysis reports according to actual needs. The reports cover dimensions such as category summary, batch analysis, and department usage, providing a basis for hospitals to optimize procurement and inventory decisions. The reports support functions such as chart display and data export, which facilitates further in-depth analysis.

[0085] During the traceability query, the entire process of medical supplies is recorded. Based on unique identification such as RFID / barcode, the system records the flow information of each medical supply from storage, outbound to replenishment throughout its life cycle, including detailed flow records such as product information, operation time, and operator, forming a complete traceability data chain.

[0086] Batch tracing and quick query can also be performed. During batch tracing, the system can query the flow trajectory of all related medical supplies in a batch based on the batch number information. Once a quality problem is found, the management personnel can quickly locate the problem batch and make subsequent disposal.

[0087] When doing a quick query: managers can use the web interface to enter keywords such as product codes and batch numbers to quickly query related traceability records. The system will intuitively display the query results in the form of timelines, lists, etc., so that managers can quickly locate the problem.

[0088] Through the application of the above-mentioned visual management and traceability query technology, the transparency and controllability of hospital medical supplies management have been effectively improved, providing strong support for refined management.

[0089] In use: A tertiary comprehensive hospital deployed the medical supplies in-and-out warehouse management and automatic replenishment system of the present invention. The materials department delivers the newly purchased medical supplies to the central warehouse. The warehouse staff uses an RFID printer to generate a unique RFID tag for each medical supply. By scanning the RFID tag with a mobile terminal, the system automatically records the storage time, quantity, batch number, expiration date and other information, and synchronizes it to the background database. Nurses in each department use a handheld mobile terminal to scan the RFID tag of the required medical supplies. The system automatically locates the specific storage location of the supplies according to the RFID tag information, and guides the nurses to the access path through voice prompts, indicator lights, etc. The mobile terminal records the variety, quantity and other data of the outbound in real time, and uploads it to the background system to complete the outbound registration. The system background monitors the inventory of various medical supplies in real time, and combines historical outbound records to perform demand forecasting and analysis. The forecasting model takes into account seasonal factors, holiday factors, etc., and can accurately predict the demand for supplies in the next week. The system automatically generates an optimized replenishment plan based on the predicted demand and the existing inventory level, and issues a purchase order to the supplier. The hospital's material management department can access the visual management module of the system through the Web terminal. The dashboard displays key indicators such as inventory levels, warehousing and outbound situations, and replenishment status of various medical supplies in real time. The system will also proactively issue reminders such as low inventory and expiration warnings based on preset warning rules. Managers can customize and generate various inventory analysis reports to provide a basis for optimizing procurement and inventory decisions. Material managers can query the full process operation records of a certain medical supply in the warehousing, outbound, replenishment and other links based on RFID tag information. At the same time, they can also view the flow information of all related supplies in a batch to ensure that product quality is traceable.

[0105] Based on implementation 2, this implementation further applies the system in implementation 1 to the application process from ward department to bed. First, a map is constructed for the trolley in implementation 2: a map of each ward of the hospital is constructed for the smart trolley, and the specific coordinates of the channels, ward locations and each bed are marked for the navigation of the trolley. Then, according to the distribution plan, the drugs are loaded onto the trolley, that is, the drugs are "entered into storage". During the operation, the drug entry management module will map the unique identifiers such as RFID tags, barcodes or QR codes in the drugs to the hospital patient identity code, so that the trolley automatically navigates to each ward according to the built-in map and the preset path planning algorithm. During the driving process, it can sense the surrounding environment in real time through sensors (such as laser radar, cameras, etc.) and avoid obstacles. After arriving at the target ward, the trolley finds the corresponding position according to the bed information. The trolley stops in front of each bed and notifies the medical staff or patients that the drugs have been delivered through prompts (such as voice, lights, etc.). The medical staff checks the drugs according to the information displayed by the trolley and takes out the drugs after confirming that they are correct. After the drug distribution is completed, the car will feed back the distribution status information (such as distribution time, recipient, etc.) to the hospital's drug management system to achieve traceability of drug distribution. When all drugs are distributed, the car returns to the drug loading point or charging area according to the preset path. If the car is low on power, it can automatically go to the charging station for charging during driving to ensure the smooth execution of the next task.

[0106] In this embodiment, multiple sensors are combined, such as laser radar, visual sensor, wheel encoder, etc. The laser radar can accurately measure the distance information of the surrounding environment; the visual sensor can identify environmental features; the wheel encoder can calculate the driving distance according to the rotation of the wheel. By fusing the data of these sensors, the positioning accuracy can be improved. High-precision sensors, such as high-resolution laser radar and high-quality visual cameras, are selected to obtain more accurate environmental information. Filtering algorithms, such as Kalman filtering and particle filtering, are used to process sensor data. These algorithms can reduce noise interference and improve data accuracy, thereby enhancing positioning accuracy. Simultaneous positioning and mapping (SLAM) algorithm optimization: Continuously optimize the SLAM algorithm so that it can more accurately build maps and locate the car. For example, improve feature extraction and matching algorithms to improve the accuracy of map construction. The positioning algorithm of the car needs to adapt to the dynamic environment in the hospital, such as people walking, beds moving, etc. By monitoring environmental changes in real time, the positioning algorithm is dynamically adjusted. The sensors are calibrated regularly to ensure the accuracy of their measurement data. For example, the distance measurement of the laser radar is calibrated, and the focal length and distortion of the visual camera are corrected.
