Description

Technical Field

[0001] This utility model relates to assistive devices for the blind, and more particularly to an assistive drug identification device for the blind. Background Technology

[0002] To help consumers use medicines correctly and with low risk, and effectively avoid consuming expired medicines, existing technologies utilize medicine identification to verify authenticity and identify the expiration date and related usage information. Medicine identification technology mainly focuses on the following two aspects.

[0003] 1) Two-dimensional barcode / QR code drug identification technology: Users scan the barcode or QR code on the medicine box with their mobile phones to jump to the relevant interface, which displays information such as the drug manufacturer, drug type, and usage instructions. Disadvantages include susceptibility to physical damage; strict requirements on the shape of the medicine; excessive curvature of the medicine box can cause distortion of the QR code or two-dimensional barcode; limited information capacity, only able to store identification codes; reliance on real-time network connection to the database; limited functionality in weak network environments; and lack of proactive interactive capabilities. 2) AI batch recognition terminal: Highly dependent on the environment: Lighting conditions, shooting angle, or packaging similarity (e.g., generic drugs) can significantly reduce recognition accuracy. Computational power and latency issues; requires high-performance terminals to support real-time processing; low-end devices have slow response times and are difficult to integrate into portable devices; database updates are lagging; when new drugs are launched or packaging changes occur, the model needs frequent retraining, resulting in high maintenance costs.

[0004] For visually impaired patients, obtaining medication information via QR code scanning is very difficult, and bulk identification terminals are inconvenient to carry. A search revealed that application publication number CN118297082A discloses a medication identification system and method, specifically a medication identification vest. The vest includes a microcontroller and an NFC identification module, with the NFC module electrically connected to the microcontroller. The medicine box includes an NFC tag for identification by the NFC module. A WeChat mini-program module is used to set the medication information in the vest. The vest also includes a communication module, through which the WeChat mini-program communicates with the vest. However, this existing technology requires wearing and locating the NFC module, making it inconvenient to use.

[0005] Therefore, designing a drug identification device that is easy for blind people to use is a technical problem that needs to be solved. Utility Model Content
