Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current negative-pressure therapy systems lack the ability to effectively monitor and adjust therapy parameters based on patient activity and environmental conditions, which can lead to suboptimal wound healing and patient compliance issues, particularly in ambulatory patients.
Innovation Solution
A system incorporating a light sensor, motion sensor, and controller that communicates with the negative-pressure source to adjust therapy parameters, including activating alerts and modifying operating modes based on ambient light and patient activity levels, promoting ambulatory therapy and reducing disruptions during sleep.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If negative-pressure therapy is applied continuously to promote wound healing, then wound healing is improved, but patient mobility and quality of life are reduced
Solution Approach 1:
The system implements periodic action by alternating between therapy delivery and patient rest/activity periods. The controller schedules negative-pressure therapy intervals followed by rest intervals, allowing patients to maintain mobility while receiving adequate wound treatment. This resolves the contradiction by making therapy delivery periodic rather than continuous.
2Reliability
If therapy parameters are adjusted based on patient activity and environmental conditions, then therapy effectiveness is improved, but system complexity increases
Solution Approach 1:
The system employs feedback mechanisms where sensors detect patient activity levels and environmental conditions (light, temperature), and the controller automatically adjusts therapy parameters based on this feedback. This allows adaptive therapy optimization without requiring complex manual intervention, resolving the contradiction between effectiveness and complexity.
Solution Approach 2:
The system performs self-service by automatically monitoring patient conditions and adjusting therapy parameters without clinician intervention. The embedded sensors and controller enable the system to autonomously optimize therapy delivery based on real-time data, reducing the need for complex external monitoring equipment.
3Loss of information
If sensors and control systems are integrated into the therapy device, then therapy monitoring and adjustment capability is improved, but device size and portability are reduced
Solution Approach 1:
The system merges multiple functions (negative-pressure delivery, sensing, processing, and control) into a single integrated device. By combining the therapy pump, sensors, processor, and user interface into one portable unit, the system achieves comprehensive monitoring capability without requiring separate bulky equipment, thus resolving the contradiction between functionality and portability.

AI summary
A system for providing therapy to a tissue site is described. The system can include a light sensor, a motion sensor, and a controller. The controller can be communicatively coupled to the source of negative pressure, the light sensor, and the motion sensor. In some embodiments, the controller can be configured to receive a first signal from the light sensor indicative of ambient light, receive a second signal from the motion sensor indicative of activity, and activate alert based on the first signal and the second signal.
