Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current programming systems for implantable fluid delivery devices lack the ability to simultaneously display graphical representations of supplemental boluses and therapy schedules, making it difficult for clinicians to manage and avoid excessive drug dosages in patients.
Innovation Solution
A device and method for programming implantable fluid delivery devices that displays both a graphical representation of a supplemental bolus and a therapy schedule, allowing clinicians to visualize and manage the delivery of medications effectively, thereby preventing excessive dosages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a programming system displays only traditional therapy schedule information, then the interface remains simple, but clinicians cannot effectively manage supplemental boluses and avoid excessive dosages
Solution Approach 1:
The patent combines multiple dosing information types (therapy schedule, supplemental boluses, priming boluses, bridging phases) into a single unified graphical display. This merging allows clinicians to view all dosage information simultaneously without switching between multiple screens or interfaces, thereby preventing information loss while maintaining interface simplicity.
Solution Approach 2:
The patent introduces a temporal dimension to the display by showing dosing information across different time periods in a single graphical interface. The display can show past, present, and future dosing events simultaneously, allowing clinicians to understand the complete dosing timeline and avoid excessive dosing by visualizing the temporal relationships between different dosing components.
2Reliability
If the programming device displays detailed dosing information including supplemental boluses and therapy schedules simultaneously, then clinicians can prevent excessive dosages, but the device complexity increases
Solution Approach 1:
The patent replaces complex manual calculations and separate tracking methods with an automated computational system that automatically calculates and displays total dosing information. The processor automatically integrates supplemental boluses, priming boluses, bridging phases, and therapy schedule doses to provide real-time feedback on total dosage, thereby enhancing safety without requiring complex manual procedures.
Solution Approach 2:
The patent creates a virtual graphical representation of the dosing regimen that mirrors the actual dosing plan. This virtual model allows clinicians to review and verify the complete dosing schedule before implementation, providing a safety check without adding physical complexity to the actual drug delivery mechanism.
3Ease of operation
If clinicians use separate displays for supplemental bolus and therapy schedule, then each display remains simple, but it is difficult to manage and coordinate dosing to avoid excessive administration
Solution Approach 1:
The patent merges separate dosing information displays into a single integrated graphical interface that shows therapy schedule doses, supplemental boluses, priming boluses, and bridging phases together. This integration allows clinicians to easily coordinate dosing by viewing all components in context, eliminating the need to mentally piece together information from separate displays while maintaining operational simplicity.

AI summary
Techniques are described for displaying a representation of a supplemental bolus and a representation of programmed doses of a therapy schedule for an implantable fluid delivery device with a programmer device. In one example, a device includes a user interface to present a graphical representation of doses of fluid to be delivered to a patient via an implantable fluid delivery device and a processor that controls the user interface to simultaneously present a first graphical representation of a supplemental bolus to be delivered by the implantable fluid delivery device and a second graphical representation of programmed doses of a therapy schedule of the implantable fluid delivery device, wherein at least a portion of the programmed doses of the therapy schedule follows delivery of the supplemental bolus by the implantable fluid delivery device. A user of the device may determine whether the representations indicate an excessive dosage risk to the patient.
