Medical Device Provisioning via RFID Storage Medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for technology that enables initial provisioning and refilling of medical devices, such as non-invasive electrical stimulation devices, but such technology does not currently exist.
Innovation Solution
A system comprising a medical device with a reader and processor, and a storage medium that allows the device to switch from a deactivated mode to an activated mode based on content read from the storage medium, with the option to refill the device by switching it back to the activated mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the medical device is activated for continuous use, then the treatment duration is extended, but the device cannot be controlled to deliver a defined number of doses or time period
Solution Approach 1:
The patent applies preliminary action by pre-programming the storage medium with a specific number of doses or time period before the device is activated. The processor reads this predetermined information from the storage medium and automatically controls the device to deactivate after the specified duration or dose count, eliminating the need for manual tracking while ensuring controlled use.
2Reliability
If the storage medium is linked to a unique medical device, then the provisioning is secure, but the storage medium cannot be reused with other devices
Solution Approach 1:
The patent extracts the unique device identification requirement by allowing the storage medium to be used with multiple devices. Instead of linking the storage medium to a specific device ID, the system verifies the presence of valid content on the storage medium itself, enabling the same storage medium to provision multiple devices while maintaining security through content validation rather than device-specific binding.
3Ease of operation
If the medical device requires manual activation and deactivation, then the device can be controlled, but the process is complex and requires user intervention
Solution Approach 1:
The patent applies self-service by enabling the medical device to automatically manage its own activation and deactivation states. The processor monitors the dose count or time period from the storage medium and autonomously transitions the device between active and deactivated states without requiring user intervention, simplifying operation while maintaining controlled delivery.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows for controlled use of medical devices by patients, ensuring they receive a defined number of doses or time period of treatment, and can be refilled as needed, providing a convenient and controlled treatment delivery method.
Implementation Method 1
the storage medium is card-shaped and the reader is configured to read the content from the storage medium via an RFID technique
Data Source
AI summary
A system is provided that includes a medical device comprising a power supply, a signal generator and an electrode. The signal generator is configured to apply one or more electrical impulses to the electrode for a period of time defined as a single dose. The system further comprises a downloadable software application coupled to the medical device. The software application is configured to switch the medical device from an activated mode to a deactivated mode after a specific number of single doses have been applied by the signal generator.
