Electrochromic Label for Medical Device Usage Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical devices, such as auto-injection devices, lack the ability to automatically indicate their usage status, making it difficult to track usage and ensure adherence to application protocols.
Innovation Solution
A labeling apparatus with an electrochromic element that changes visibility in response to an electric current, integrated with a medical device, allowing it to display a predetermined feature indicating usage, and a scan device to record and confirm the usage status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional static label is used on a medical device, then the device structure remains simple, but the label cannot automatically reflect the real-time usage status of the device
Solution Approach 1:
The patent applies electrochromic material that changes color or optical properties in response to electrical signals. The label transitions from a transparent or light state (indicating unused) to a dark or colored state (indicating used), providing automatic visual feedback of device status without adding complex mechanical components
Solution Approach 2:
The patent replaces traditional mechanical indicator systems (such as physical flags, moving parts, or complex mechanical switches) with an electrical system. A simple circuit with a power source and electrochromic material provides status indication through color change, reducing mechanical complexity while enabling automatic status reflection
2Ease of operation
If no usage indication is provided on the medical device, then the device remains simple to manufacture, but users cannot easily determine whether the device has been used
Solution Approach 1:
The label system is self-activating through the device's own power source. When the medical device is used, the power source automatically provides electrical current to the electrochromic material, causing it to change appearance and indicate usage status without requiring external intervention or complex control systems
Solution Approach 2:
The patent implements automatic feedback by connecting the electrochromic label to the device's power source through a switch mechanism. When the device transitions from unused to used state, the circuit closes and the label automatically displays the changed status, providing real-time feedback to users about device usage
3Extent of automation
If a dynamic status-indicating label is implemented on the medical device, then usage tracking is automatically enabled, but additional components (power source, switch, electrochromic material) are required
Solution Approach 1:
The patent merges the label with existing device components. The electrochromic material is integrated into the device housing or label structure, the power source utilizes the device's existing battery, and the switch mechanism leverages the device's operational movements (such as plunger insertion or cartridge ejection), thereby reducing the need for separate additional components
Solution Approach 2:
The patent makes existing device components serve multiple functions. The power source not only operates the medical device but also powers the status indicator. The switch mechanism not only controls device operation but also activates the label display. This multi-functionality reduces overall system complexity despite adding automation capabilities

Data Source
AI summary
An apparatus for presenting an application status of a medical device that has a unused state and a used state. The apparatus includes a label having an electrochromic element. The label is at least partially disposed on an exterior surface of the medical device and is configured to display a predetermined feature in response to an electric current. A power source is disposed in or on the medical device for providing the electric current. A switch is configured to selectively connect or disconnect the label and the power source to one another for controlling the application of the electric current to the electrochromic element in response to actuation of the medical device from the unused state to the used state. The label may be scanned by a scan device that may connect to a medical organization for communicating information between the scan device and the medical organization.
