Capacitive Eye Drop Storage Unit for Compliance Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elderly patients with eye complications, such as glaucoma, face difficulties in adhering to complex eye drop medication regimes due to challenges in understanding and administering medications, leading to non-adherence and potential blindness, exacerbated by the need for multiple eye drop medications with different dispenser shapes and sizes.
Innovation Solution
An eye drop bottle storage unit equipped with sensors and a processor that tracks the administration of eye drops by measuring liquid levels using capacitive sensors, computes compliance factors, and alerts patients and healthcare professionals to ensure adherence to medication regimens, with features like audio signals, indicator lights, and automatic reordering of medications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elderly patients are provided with multiple eye drop medications with different dispenser shapes and sizes, then the treatment effectiveness for eye complications can be improved, but the ease of operation deteriorates due to difficulties in understanding and remembering which medication to administer
Solution Approach 1:
The system segments the medication administration process into distinct components: each eye drop bottle is individually tracked with unique identifiers, and the storage unit provides separate designated locations for each bottle type. This segmentation helps elderly patients distinguish between different medications and their administration schedules without confusion.
Solution Approach 2:
The system incorporates feedback mechanisms including sensors that detect when bottles are removed or returned to the storage unit, and a user interface that provides real-time confirmation of correct medication selection and administration timing. This feedback loop guides patients through the complex regimen and confirms proper compliance.
2Measurement precision
If complex monitoring systems are implemented to track medication administration, then compliance monitoring accuracy is improved, but the device complexity increases
Solution Approach 1:
The storage unit serves multiple functions: it stores multiple eye drop bottles, tracks their removal and return, monitors compliance, provides user guidance, and communicates with healthcare providers. By consolidating these functions into a single device, the system achieves high monitoring accuracy without proportionally increasing overall system complexity.
Solution Approach 2:
The system automatically tracks medication administration through sensors that detect bottle removal and return without requiring manual input from patients. The compliance calculation and alert generation occur automatically, reducing the operational complexity for users while maintaining high monitoring precision.
3Ease of operation
If manual tracking of eye drop administration is used, then the ease of operation is maintained, but the loss of information increases due to patient inability to remember and recall medication regimens
Solution Approach 1:
The storage unit acts as an intermediary between the patient and the medication regimen information. It automatically records all interactions with the bottles and calculates compliance, eliminating the need for patients to manually track or remember administration details while preserving complete information about actual compliance behavior.
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 significantly improves patient compliance with eye drop administration, reducing the risk of blindness and medication wastage by ensuring accurate and timely administration of eye drops, while also providing real-time monitoring and alerts for adherence.
Implementation Method 1
The one or plurality of sensors include capacitive sensors placed at predefined positions along the length of each eye drop bottle in each eye drop bottle pod, and where the processor is configured to determine whether the subject administered eye drops from each eye drop bottle by computing a height of a liquid in each eye drop bottle using capacitance measurements computed from the signals received from the capacitive ring sensors.
Data Source
AI summary
An eye drop bottle storage unit for eye drop administration compliance includes a memory, a processor, and one or a plurality of eye drop bottle pods, where each eye drop bottle pod of the one or said plurality of eye drop bottle pods is configured to hold an eye drop bottle, and comprises one or a plurality of sensors. The memory is configured to store data of an eye drop administration regime of a subject. The processor is configured to receive signals from the one or said plurality of sensors of each eye drop bottle pod, and to determine from the received signals whether the subject administered eye drops into eyes of the subject from each eye drop bottle respectively held in each eye drop bottle pod of the one or said plurality of eye drop bottle pods in accordance with the eye drop administration regime data.
