Adhesive Patch and Applicator Wireless Verification for Injection Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients requiring regular subcutaneous injections, such as diabetics or those with HIV or arthritis, face challenges in adhering to proper medication administration guidelines without the assistance of a healthcare professional, which can lead to errors in timing and dosage due to the lack of automated systems for self-administration.
Innovation Solution
A system comprising an adhesive patch with designated injection sites and a subcutaneous medication delivery applicator (SMDA) that uses short-range wireless communication to verify association and authorize medication delivery, ensuring proper timing and dosage adherence through safety interlocks and sensors for skin contact detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a system with automated verification and control logic is implemented, then medication administration accuracy and patient safety are improved, but device complexity increases
Solution Approach 1:
The adhesive patch acts as an intermediary device that simplifies the verification process. It contains control logic and wireless communication interfaces that automatically verify medication authorization and timing, eliminating the need for complex manual verification procedures while maintaining high reliability
Solution Approach 2:
The system performs self-verification through automated control logic embedded in the adhesive patch and SMDA. The devices automatically check authorization, verify timing intervals, and control safety interlocks without requiring external monitoring, reducing overall system complexity while improving reliability
2Reliability
If wireless communication interfaces and control logic are added to verify authorization, then unauthorized use is prevented, but the ease of operation is reduced
Solution Approach 1:
The adhesive patch and SMDA automatically perform authorization verification through embedded control logic and wireless communication. The system self-checks timing intervals and authorization status without requiring patient intervention, maintaining ease of operation while ensuring reliable authorization verification
Solution Approach 2:
The system performs preliminary verification of authorization and timing intervals before allowing medication delivery. The control logic checks all conditions in advance and only permits operation when fully authorized, preventing unauthorized use while keeping the actual injection process simple
3Measurement precision
If multiple safety interlocks and verification mechanisms are implemented, then medication timing and dosage accuracy are improved, but the device complexity increases
Solution Approach 1:
The adhesive patch serves as an intermediary that consolidates multiple safety functions. It contains control logic, wireless communication interfaces, and timing verification mechanisms that work together to ensure precise dosage and timing while presenting a simple interface to the user
Solution Approach 2:
Multiple safety functions including timing verification, authorization checks, and dosage control are merged into the adhesive patch and SMDA system. The control logic integrates these functions to achieve precise medication delivery without requiring separate complex devices for each function

AI summary
Described herein are subcutaneous medication delivery applicators and adhesive patches with one or more openings in the patches that designate one or more desired injection sites for subcutaneous injection of a medication. The medication delivery applicator and the adhesive patch may both include circuitry and wireless short-range communications interfaces that allow for the two devices to communicate with one another in order to determine if they are pre-associated in some manner, such as would be the case if both devices were packaged in the same injection kit. The medication delivery applicator may have some form of safety interlock that is only disengaged by the circuitry upon verifying that the two devices are pre-associated in some manner. Various other implementations are described as well.
