Description

Technical Field

[0001] This invention belongs to the technical field of cross-application of hospital information management and intelligent identification technology, and also involves the deep integration of medical compliance supervision and biometric identification. Specifically, it is an integrated system and method for pharmacy window operations based on intelligent traceability and identification technology, mainly applied to the drug dispensing management of medical institution pharmacies. Background Technology

[0002] Currently, the mainstream solution for hospital dispensing relies on the integration of distributed devices (such as barcode scanners, document scanners, and facial recognition terminals for special medications) with the hospital's HIS system to meet drug management needs. However, existing technologies generally suffer from the following problems:

[0003] 1. Dispersed hardware and redundant operation: Traditional dispensing window equipment such as high-speed scanners, card readers, barcode scanners, and facial recognition terminals for special-managed drugs are deployed independently. Pharmacists need to operate across systems (such as switching to the HIS system and the traceability code management system), which results in a single prescription dispensing verification taking more than 20 seconds, resulting in low efficiency and serious underutilization of window space.

[0004] 2. Insufficient Intelligent Traceability Management: The existing system lacks an intelligent early warning mechanism for expiration dates, relying on manual judgment to intercept expired drugs and substandard batches. This management loophole may lead to expired drugs and substandard batches being used in clinical practice, thereby increasing public health and safety risks, medical disputes, and exacerbating the waste of medical resources.

[0005] 3. Exploration of the Application of Biometric Technology in the Medical Field: Biometric technologies (such as facial recognition and finger vein recognition) have been initially applied in the medical field. Currently, drug traceability systems only support verification of drug information via traceability codes and cannot automatically link the identity of the person receiving the medication. For the distribution of specially managed drugs, it is necessary to complete traceability code scanning + facial verification + ID card reading. The existing equipment operates in a decentralized manner, resulting in a lengthy process that takes more than 50 seconds in total. There is an urgent need for an integrated terminal to reduce congestion at the dispensing window. Summary of the Invention

[0006] To address the problems existing in current technologies, this invention provides an integrated system and method for pharmacy window operations based on intelligent traceability and identification technology. This technology integrates functions such as automatic identification of drug traceability codes, optimization of pharmacy business processes, multi-system data collaboration, and intelligent early warning. Furthermore, it integrates biometric technology (such as facial recognition systems) for the dispensing of specially managed drugs (such as narcotic drugs and psychotropic drugs). The main objective is to achieve high efficiency, intelligence, and compliance in pharmacy window operations by constructing a full-process traceability system that combines "hardware integration and software intelligence." The core focus is on improving dispensing efficiency, enhancing traceability accuracy, and integrating biometric technology to meet drug traceability requirements and special drug regulatory requirements.

[0007] The technical solution of this invention is: an integrated pharmacy window business system based on intelligent traceability and identification technology, comprising an integrated hardware architecture and intelligent software system modules;

[0008] The integrated hardware architecture includes a pharmacist operating terminal and a patient operating terminal that are fixedly connected back to back.

[0009] The pharmacist operating terminal is equipped with a pharmacist operating screen, a pharmacist operating terminal storage platform, and a visual deep learning barcode scanning module. The visual deep learning barcode scanning module uses an industrial-grade high-definition camera and supports barcode recognition within 0.3 seconds. The pharmacist operating screen is located at the center of the front of the pharmacist operating terminal. The pharmacist operating terminal storage platform is located below the pharmacist operating screen and can hold a medicine basket. The industrial-grade high-definition camera is located directly above the pharmacist operating terminal storage platform.

[0010] The patient operating terminal is equipped with a patient interaction screen and a biometric terminal; the biometric terminal integrates an infrared liveness detection face recognition module with a recognition speed of ≤0.5 seconds and an ID card and medical insurance card reader; the infrared liveness detection face recognition module uses a face recognition camera; the patient interaction screen is located at the top of the patient operating terminal, the face recognition camera is located at the top of the patient interaction screen, and the ID card and medical insurance card reader is located inside the bottom plate of the patient operating terminal, and the bottom plate of the patient operating terminal is marked with an ID card and medical insurance card reading area;

[0011] The intelligent software system module includes an intelligent identity recognition module, a traceability code verification module, a multi-system data collaboration module, and an HIS system interface component for connecting to the HIS system. The intelligent identity recognition module performs identity verification based on the biometric terminal, comparing the ID card number corresponding to the face identified by the infrared liveness detection face recognition module with the ID card number identified by the ID card or medical insurance card, supporting an accuracy rate of ≥99.5% for identity verification, ensuring consistency between the person and the identification document.

[0012] The traceability code verification module parses the first 7 digits of the drug's traceability code, automatically matches the drug's basic information, connects to the code-based security interface to obtain drug information, verifies batch number compliance in real time, and automatically locks the drug inventory if an unqualified batch number is detected.

[0013] The multi-system data collaboration module connects to the HIS system based on the HIS system interface component, enabling abnormal behavior monitoring and triggering early warnings for abnormal situations.

[0014] Furthermore, the intelligent software system module also includes an expiration date warning module. This module sets an expiration date warning threshold of N months from the expiration date, where N is greater than or equal to 3. The system automatically highlights drugs nearing their expiration date and intercepts expired drugs from leaving the warehouse. N is preferably 6.

[0015] Furthermore, the abnormal situations include the same patient receiving special medications multiple times in a single day, and medications being dispensed outside of working hours. The special medications include anesthetic drugs and psychotropic drugs.

[0016] Furthermore, the multi-system data collaboration module can systematically collect and analyze patient feedback, forming a closed-loop service cycle of medication dispensing, evaluation, and improvement. This enhances pharmacy service quality and patient satisfaction.

[0017] Furthermore, the multi-system data collaboration module is capable of prescription reception: real-time acquisition of the HIS prescription queue; prescription confirmation: synchronously updating the HIS prescription status to "prescription issued"; traceability feedback: transmitting the prescription time, operator, and traceability code information back to the medical insurance traceability platform management backend module; and traceability data reports: automatically generating monthly traceability code collection rate reports and expiration date warning processing records.

[0018] Furthermore, the patient interaction screen is tilted upwards by 30° to adapt to the operating angle, making it easy for the patient to observe the screen while standing.

[0019] Furthermore, the intelligent identity recognition module uses a CNN neural network algorithm to perform liveness detection on 68 key points of facial feature points to prevent photo and video forgery, and outputs a confidence score for identity verification. A score of ≥80 is considered passing.

[0020] Furthermore, the recognition accuracy of the industrial-grade high-definition camera is ≥99.99%.

[0021] This invention also provides a dispensing method implemented by a pharmacy window service integrated system based on intelligent traceability and identification technology, the specific steps of which are as follows:

[0022] Step 1: The pharmacist scans the drug traceability code using the visual deep learning scanning module, and the system automatically links it to the HIS prescription information, taking ≤1 second;

[0023] Step 2: For special drugs, trigger the facial recognition module. The patient or agent scans their face using the infrared liveness detection facial recognition module to read their ID card number. The system automatically compares the identity information and binds the traceability code, taking ≤2 seconds.

[0024] Step 3: The pharmacist's operating screen and the patient's interactive screen simultaneously display drug information, patient identity, and expiration date warnings. Drugs nearing their expiration date are automatically highlighted in red. After the pharmacist confirms, they click to dispense the medication, which takes ≤2 seconds.

[0025] The beneficial effects of this invention are:

[0026] 1. Significant Improvement in Dispensing Efficiency and Process Optimization: Through integrated hardware and software process refactoring, the single prescription dispensing verification time has been reduced from over 20 seconds in the traditional model to within 5 seconds, with an estimated efficiency improvement of over 60%. Hardware integration consolidates scattered devices such as document scanners and barcode scanners into intelligent workstations, reducing cross-system operation steps for pharmacists. Furthermore, in the special drug dispensing process, the automated linkage of facial recognition and traceability code verification reduces manual verification time and effectively alleviates window congestion.

[0027] 2. Enhanced accuracy and safety management of drug traceability: The system uses an intelligent expiration date warning module (with a 6-month warning threshold) to verify non-compliant batch numbers in real time, automatically intercepting expired drugs and problematic batch numbers. This improves the interception rate by 99% compared to traditional manual judgment, solving the problem of expiration date errors, reducing medical disputes, and ensuring patient medication safety.

[0028] 3. Dual guarantee of compliance and operational safety in special drug supervision: The integrated facial recognition system uses biometric technology and ID card reading to achieve real-time binding of "person-drug-prescription" information, reducing the risk of fraudulent claims and meeting the "technical prevention" requirements of Shanghai's 2019 special drug supervision plan.

[0029] 4. Data-driven support for patient satisfaction and management decisions: The satisfaction assessment module collects patient feedback in real time through an interactive screen. Keyword analysis automatically categorizes high-frequency issues and optimizes processes based on dispensing efficiency data. The satisfaction trend charts and reports generated in the management backend provide data support for pharmacy performance evaluation and equipment allocation, improving service improvement efficiency by 50% compared to experience-based management models.

Detailed Implementation

[0035] The present invention will now be further described with reference to the accompanying drawings.

[0036] The technical solution proposed in this application aims to solve three core technical problems existing in the current hospital drug dispensing process:

[0037] 1. Dispersed hardware and redundant operations: In traditional dispensing windows, devices such as high-speed scanners, card readers, barcode scanners, and facial recognition terminals for special drugs are deployed independently, resulting in cumbersome cross-system operations for pharmacists. The dispensing and verification of a single prescription takes more than 20 seconds, and the dispensing of specially managed drugs takes more than 50 seconds, which is inefficient.

[0038] 2. Insufficient intelligence in traceability management: The existing system lacks an intelligent early warning mechanism for expiration dates, and the interception of expired drugs and unqualified batches relies on manual judgment, which poses public health and safety hazards and the risk of medical disputes.

[0039] 3. Insufficient integration of biometric technology: In the management of special drugs, the face verification terminal has no data interaction with the HIS and traceability system, and it is necessary to manually complete the "traceability code scanning + face verification + ID card reading", which is a lengthy process and causes congestion at the window.

[0040] To address the aforementioned issues, this embodiment provides an integrated system and method for pharmacy window operations based on intelligent traceability and identification technology. This technology integrates functions such as automatic identification of drug traceability codes, optimization of pharmacy business processes, multi-system data collaboration, and intelligent early warning. Furthermore, it integrates biometric technology (such as facial recognition systems) for the dispensing of specially managed drugs (such as narcotic drugs and psychotropic drugs). The main objective is to achieve high efficiency, intelligence, and compliance in pharmacy window operations by constructing a full-process traceability system that combines "hardware integration and software intelligence." The core focus is on improving dispensing efficiency, enhancing traceability accuracy, and integrating biometric technology to meet drug traceability requirements and special drug regulatory requirements.

[0041] (I) Hardware Integrated Platform Design

[0042] Integrated hardware architecture: Design an intelligent workstation that integrates the following modules:

[0043] Dual-screen display system: pharmacist operation screen 1 (14-inch touch screen) and patient interaction screen 5 (10-inch LCD screen). The tilt angle of the patient interaction screen is optimized to tilt upwards by 30° to adapt to the operating angle, so that patients can see the screen when they are standing.

[0044] Visual deep learning barcode scanning module: Employs an industrial-grade high-definition camera 4, which is positioned above the pharmacist's operating platform 2 on the pharmacist's operating terminal 3. The camera is encased in sheet metal. It supports barcode recognition within 0.3 seconds with a recognition accuracy rate ≥99.99%.

[0045] Biometric terminal: Integrates an infrared liveness detection facial recognition module (recognition speed ≤ 0.5 seconds) with an ID card and medical insurance card reader. The facial recognition camera 6 of the infrared liveness detection facial recognition module is located at the top of the patient interaction screen on the patient operating terminal for facial recognition. An ID card and medical insurance card reading area 7 is located on the bottom plate of the patient operating terminal for recognizing ID cards and medical insurance cards. It supports an accuracy rate of ≥ 99.5% for identity verification. The identity verification involves comparing the ID card number corresponding to the face recognized by the infrared liveness detection facial recognition module with the ID card number recognized by the ID card or medical insurance card to ensure consistency between the person and the document.

[0046] Hardware Collaboration Workflow

[0047] The dispensing process is as follows: The pharmacist scans the drug traceability code using a visual deep learning scanning module. The system automatically links the prescription information to the HIS (Hospital Information System, a comprehensive hospital management platform including modules for billing, outpatient services, emergency services, and inpatient services) (time ≤ 1 second). For special drugs, the facial recognition module is triggered. The patient or their representative scans their ID card number using an infrared liveness detection facial recognition module. The system automatically compares the identity information with the ID card and binds the traceability code (time ≤ 2 seconds). The dual-screen display system simultaneously shows the drug information, patient identity, and expiration date warning (drugs nearing their expiration date are automatically highlighted in red). After the pharmacist confirms, they click to dispense the drug (time ≤ 2 seconds).

[0048] (II) Construction of Intelligent Software Systems

[0049] Core functional modules

[0050] Intelligent identity recognition module:

[0051] The CNN neural network algorithm is used to perform liveness detection on facial feature points (68 key points) to prevent photo and video forgery, and output the confidence score of the identity verification (a score ≥80 is considered passing).

[0052] Traceability code verification and expiration date warning module:

[0053] The first 7 digits of the traceability code are analyzed to automatically match the basic drug information (manufacturer, approval number, etc.).

[0054] The expiration date warning threshold is set at 6 months from the expiration date. The system automatically highlights drugs nearing their expiration date in red and blocks expired drugs from leaving the warehouse. It connects to the "Code for Assurance" interface to verify the compliance of batch numbers in real time. If an unqualified batch number is found, the drug inventory is automatically locked.

[0055] Multi-system data collaboration module:

[0056] Develop an HIS system interface component (based on WebServices interface) to achieve the following data interaction:

[0057] Prescription Receipt: Real-time acquisition of the HIS prescription queue for medications to be dispensed;

[0058] Medication dispensing confirmation: The HIS prescription status is updated to "Dispensed" simultaneously;

[0059] Traceability and Feedback: The medication dispensing time, operator, and traceability code information are fed back to the medical insurance traceability platform management backend module.

[0060] Workload statistics: Statistics on the number of medications dispensed and the number of special drug verifications by pharmacist, window, and time period;

[0061] Traceability data reports: Automatically generate monthly traceability code collection rate reports (≥99%) and expiration date warning processing records;

[0062] Abnormal behavior monitoring: triggers alerts for abnormal situations such as the same patient receiving special medications multiple times in a single day or dispensing medications outside of working hours;

[0063] Satisfaction assessment: Systematically collect and analyze patient feedback to form a service loop of "dispensing-evaluation-improvement" and improve pharmacy service quality and patient satisfaction.

[0064] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
