Problem
Conventional external infusion pumps face concerns regarding the security and accuracy of wireless communications, as RF transmissions can be susceptible to interception or manipulation, potentially leading to harmful changes in medication delivery.
Innovation Solution
A disease management system that includes a medical device and a remote controller, utilizing RFID tags with unique codes for faster pairing and verification of accurate signal exchange, ensuring correct device pairing and preventing malicious or corrupted signals by requiring proximity for information exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RF communication is used for remote controller and infusion pump communication, then wireless control capability is improved, but security against interception and manipulation deteriorates
Solution Approach 1:
The system performs preliminary pairing and verification actions before actual medication delivery control. The remote controller and infusion pump establish a trusted relationship through identification exchange and verification in advance, so that when RF communication is used for control, the security risk is already mitigated by the pre-established trust relationship.
Solution Approach 2:
The patent introduces an intermediary verification mechanism where identification information is exchanged and verified between the remote controller and infusion pump. This intermediary step acts as a security layer between the RF communication channels, ensuring that only authenticated devices can communicate medication delivery instructions.
2Adaptability or versatility
If traditional pairing methods are used, then device connectivity is achieved, but risk of incorrect pairing increases
Solution Approach 1:
The system implements feedback mechanisms where the infusion pump displays the remote controller's identification information and the remote controller displays the infusion pump's identification information. This visual feedback allows users to verify that the correct devices are paired before medication delivery control is enabled, preventing incorrect pairing risks.
3Ease of operation
If RF transmission is used for communication, then remote control functionality is improved, but susceptibility to corrupted or malicious signals increases
Solution Approach 1:
The system applies preliminary anti-action by requiring identification verification and pairing confirmation before allowing RF transmission of medication delivery instructions. This pre-emptive measure counteracts potential corrupted or malicious signals by establishing authentication requirements that would prevent unauthorized or erroneous control commands.
