[0145] Detailed explanation of data processing for key functional modules of the distribution system of this invention:

[0146] (1) Encryption process for medication data and patient information

[0147] To ensure the security of patient identity and prescription information during transmission, storage, and retrieval, this system employs the following encryption strategies:

[0148] Standardized data encapsulation format: After the medical order information is transferred through the HIS interface, it is uniformly structured into JSON format, with fields including: patient ID (UID), drug code, dosage, medication period, contraindications, etc.

[0149] Sensitive field encryption (field-level encryption): Use ECC (elliptic curve cryptography) to encrypt the "UID, prescription number" fields; use AES-256 to perform symmetric encryption on large fields such as "medication record, diagnosis summary".

[0150] Digital signature mechanism: Generate medical order digest using SHA-256 hash digest; use the hospital's private key to sign the digest to ensure that the data has not been tampered with when downstream calls are made.

[0151] Transport layer encryption: Data is transmitted encrypted between modules via the HTTPS (TLS 1.3) protocol; including links such as the hospital HIS-medicine bag printing system and the cloud server-patient app.

[0152] Access control: The system adopts the RBAC role-based access control model to distinguish the access permissions of hospital administrators, pharmacists and patients; each access is automatically written to the log for subsequent auditing.

[0153] (2) Mechanism for detecting and recognizing the integrity of QR code printing

[0154] This system ensures that every QR code on the medicine bag can be scanned and recognized by devices and mobile phones, avoiding interruption of patient information caused by "scanning failure".

[0155] QR code content structure verification: Each QR code includes the following fields: patient UID + medicine bag number + medicine code + check digit (CheckSum); the system runs a verification algorithm before printing to ensure data integrity.

[0156] Image-level sharpness simulation recognition: After the system generates a QR code, it calls an image recognition module (such as OpenCV) to simulate recognition once and detect contrast / edge recognition.

[0157] Physical back-scan verification mechanism: After printing, the medicine bag passes through the "back-scan recognition module"; a high-speed scanning head is used for OCR recognition to confirm that the QR code can be accurately decoded.

[0158] From identification failure to exception labeling and removal: If identification fails, the medicine bag will be pushed to the exception removal channel; at the same time, the backend records the medicine bag number and error type.

[0159] (3) Precise transport and positioning process for medicine bags

[0160] To ensure accurate positioning of the medicine bag during printing and scanning, the system incorporates the following control mechanisms:

[0161] Transmission path perception initialization: After the medicine bag is placed, the sensor detects the edge of the bag; the size and initial offset of the medicine bag are identified by an infrared alignment light source.

[0162] Correction control algorithm (closed-loop control): The system uses "sensor + stepper motor" linkage; if the detected offset exceeds 0.5mm, the servo mechanism starts lateral fine adjustment; the control signal is corrected in real time based on PID algorithm.

[0163] Position confirmation and locking mechanism: After reaching the printing position, the vacuum adsorption stage is activated to fix the bag; printing can only be performed after the system feedback that the positioning status is "Ready".

[0164] Displacement encoder report and deviation warning: The transmission mechanism contains a linear encoder that records the trajectory of each medicine bag; when the deviation exceeds the standard, a "transmission deviation" alarm is triggered and the printing queue is suspended.

[0165] Scalable data processing mechanism:

[0166] Each medicine bag is assigned a unique ID (bag code) to record the printing time, personnel, and status;

[0167] Integrate with the BI statistics module to analyze print pass rate and fault distribution;

[0168] Supports exporting electronic logs for traceability by QA and regulatory authorities.

The middle roller 45 is positioned between the third rollers 44 and the fourth rollers 46. The two third rollers 44 and the two fourth rollers 46 are positioned vertically, with one end of each roller located on one side of the frame 2, and one end of each third roller 44 located on the other side of the frame 2. Figure 6 As shown, the wrapping method of the medicine bag roll can straighten the medicine bag during transport, and can also be finely adjusted by the correction motor.

[0181] The CCD image recognition device is located at the end of the double-track clamping structure and is used to compare the pre-printed mark on the medicine bag with the real-time positioning mark to ensure the accuracy of the printing position.

[0182] In some embodiments of the present invention, the medicine bag cutting and dispensing mechanism 5 includes:

[0183] Medicine bag cutting mechanism, used to cut medicine bags to specified dimensions;

[0184] The bag dispensing mechanism is used to accurately deliver the cut medicine bags to the dispensing opening, making it convenient for patients or automated terminals to pick up their medications.

[0185] In some embodiments of the present invention, the control system module 6 includes:

[0186] The touchscreen 61 is used to configure working parameters, synchronize prescription data, and view logs and error information.

[0187] The central processing unit is used to process the received instructions and provide feedback to the equipment operation.

[0188] The sending unit is used to send the device's operating status and historical print records to the maintenance personnel's mobile APP.

[0189] In this embodiment, the printing mechanism adopts a closed slide rail structure, is equipped with a piezoelectric printhead (brand not specified), and has the following key structures:

[0190] The nozzle mount can move precisely along the X-axis, and its positioning is controlled by a stepper motor and a synchronous belt.

[0191] A micro-negative pressure adsorption and leveling platform is provided in front of the nozzle to ensure that the surface of the resealable bag is tightly adhered and to avoid wrinkles.

[0192] Immediately after printing, start the UV curing lamps or hot air device simultaneously to ensure the ink dries quickly and prevents adhesion.

[0193] The printhead cavity is equipped with an internal circulation ink path structure. When the equipment is idle for more than a set time, the system automatically performs low-frequency pulse jet spraying from the nozzle. Combined with the impurity removal and drainage pipe, it removes residual impurities from the printhead cavity, effectively extending the printhead life and reducing the maintenance frequency.

[0194] Conveying and correction mechanism:

[0195] The conveying path uses a double-track clamping structure, with a built-in static elimination device to prevent the bag from floating.

[0196] The system uses a dual-side guide rail automatic correction structure with a built-in high-precision photoelectric alignment sensor to detect the bag offset in real time and make fine adjustments through a correction motor.

[0197] A CCD image recognition window is installed at the end of the conveying path to compare the pre-printed mark on the bag with the real-time positioning mark, so as to further ensure the accuracy of the printing position.

[0198] This invention can also be applied to other feeding modes, specifically including:

[0199] Single-sheet feeding method: By setting up a stacked feeding bin, sheet-separating components, and linear pushing track, the medicine bags are fed and positioned one by one.

[0200] Combined feeding method: It is equipped with a switchable feeding interface, which allows operators to switch to roll or single sheet input mode according to the needs of the site, and has high adaptability and scene compatibility.

[0201] The all-in-one machine startup and maintenance mechanism of this invention:

[0202] It supports "print upon power-on" mode, automatically completing steps such as cleaning, calibration, and liquid level detection in standby mode.

[0203] The nozzle has a self-healing function. When nozzle blockage or misalignment is detected, it automatically starts a low-frequency pulse cleaning mode and prompts maintenance personnel to check.

[0204] All actions can be remotely set via the touchscreen, and maintenance personnel can also log in via an app to view historical printing records and equipment operating status.

[0205] The above is a further detailed description of the present invention and should not be considered as a limitation on the specific implementation of the present invention. For those skilled in the art, simple deductions or substitutions without departing from the concept of the present invention are all within the protection scope of the present invention.
