Pain Management System with Sleep State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pain management systems rely heavily on patient feedback, which is subjective and time-consuming, making it difficult to optimize pain suppression therapies as they are affected by varying physical, physiological, and mental states, especially during sleep, where physiological conditions differ significantly from wakefulness.
Innovation Solution
A system that includes a sleep monitoring circuit to determine the patient's sleep state using various sensors and a control circuit to adjust pain relief therapy parameters based on the sleep state, ensuring timely and optimized pain management by integrating sleep monitoring with pain relief delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If patient feedback is used for pain management assessment, then subjective pain information can be obtained, but the treatment optimization is delayed and inefficient
Solution Approach 1:
The patent replaces the manual patient feedback mechanism with an automated physiological signal monitoring system. Sensors continuously collect objective physiological data (heart rate, respiration, muscle activity) and algorithmically determine pain levels, eliminating the time delay inherent in patient self-reporting and enabling real-time treatment optimization.
Solution Approach 2:
The system enables self-monitoring of pain states through automated physiological signal analysis. The device continuously assesses pain levels without requiring active patient participation or feedback provision, allowing the treatment system to autonomously detect pain changes and adjust therapy parameters in real-time.
2Reliability
If pain management therapy is continuously delivered, then pain suppression is maintained, but energy consumption increases
Solution Approach 1:
The patent implements dynamic therapy delivery that adapts to real-time pain states. The system continuously monitors physiological signals, detects actual pain levels, and adjusts or pauses therapy delivery accordingly. This dynamic approach maintains effective pain suppression only when needed, significantly reducing energy consumption compared to continuous therapy delivery.
Solution Approach 2:
The system employs closed-loop feedback control where physiological signals provide real-time information about pain states. This feedback enables the therapy delivery mechanism to respond appropriately - delivering therapy when pain is detected and reducing or stopping therapy when pain is absent, thereby optimizing the balance between effectiveness and energy consumption.
3Adaptability or versatility
If sleep monitoring is integrated with pain management, then therapy optimization during sleep is achieved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single unified system. The same physiological sensors and processing circuits serve both sleep monitoring and pain management functions. By making the system multi-functional, the patent achieves therapy optimization during sleep without proportionally increasing device complexity, as the infrastructure is shared across functions.
Solution Approach 2:
The patent merges sleep monitoring and pain management systems into an integrated platform. The physiological signal acquisition, processing, and analysis components are combined, allowing the system to simultaneously or alternatively perform sleep stage detection and pain level assessment using the same hardware and software resources, thereby minimizing overall system complexity.

The one or more sleep signals may include one or more physiological signals corresponding to the sleep state of the patient. The pain relief device may be configured to deliver one or more pain relief therapies. The control circuit may be configured to control the delivery of the one or more pain relief therapies using therapy parameters and to adjust the therapy parameters based on the determined sleep state.
