Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices for health monitoring lack integrated mechanisms to actively challenge user responsiveness during opioid-induced respiratory depression (OIRD) and administer antidotes promptly, especially in remote or unmonitored locations, increasing the risk of severe injury or death.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional health monitoring wearables are used, then basic physiological monitoring is provided, but they lack integrated mechanisms to actively challenge user responsiveness and administer antidotes promptly
Solution Approach 1:
The patent combines multiple previously separate functions into a single integrated wearable device: physiological monitoring sensors, challenge-response system (speaker, microphone, processor), stimulus delivery mechanisms (vibrator, speaker for acoustic stimulation), and automated antidote injection system. This merging enables the device to autonomously detect opioid-induced respiratory depression through challenge-response protocols and immediately administer naloxone without requiring external intervention, thereby improving reliability while managing complexity through integration.
Solution Approach 2:
The wearable device is designed with multi-functionality to serve various purposes: continuous physiological monitoring (oximetry, heart rate, respiratory rate), active challenge-response testing to assess responsiveness, physical stimulus delivery for arousal attempts, and automated antidote administration. This universal design allows a single device to handle the entire overdose response workflow from detection to treatment, addressing the limitation of traditional single-function wearables.
2Measurement precision
If automated challenge-response systems are implemented, then early OIRD detection is improved, but response time for antidote administration must be reduced
Solution Approach 1:
The device performs preliminary actions by continuously monitoring physiological parameters and actively challenging user responsiveness through structured protocols before actual overdose symptoms fully manifest. The challenge-response system periodically tests user awareness and responsiveness, allowing the device to detect early signs of opioid-induced respiratory depression and initiate antidote administration before the condition deteriorates, thereby reducing the critical time loss for treatment.
Solution Approach 2:
The system implements continuous feedback loops where physiological sensors monitor vital signs, challenge-response protocols assess neurological status, and the processor analyzes this data in real-time to determine overdose likelihood. This feedback mechanism enables precise early detection of OIRD and triggers automated naloxone injection immediately when thresholds are exceeded, minimizing the time between detection and treatment by eliminating manual assessment delays.
3Reliability
If the device operates autonomously in remote locations, then survival rates improve, but communication reliability becomes challenging
Solution Approach 1:
The wearable device is designed to operate autonomously without requiring external communication infrastructure or human intervention. It self-monitors physiological parameters, self-assesses user responsiveness through challenge protocols, self-administers antidote injection, and self-manages emergency notifications to pre-configured contacts. This self-service capability ensures the device can reliably improve survival rates in remote locations where communication networks may be unavailable or unreliable, as the critical treatment function does not depend on external communication.

AI summary
A novel and useful respiratory monitoring system and related methods that can interact with an opioid user and initiate a lifesaving drug injection process to mitigate opioid induced respiratory depression in an opioid user when detected. The system employs a progressive challenge-response system to detect unresponsiveness, deliver physical stimuli, administer one or more doses of an antidote, and transmit notifications, thereby improving survival rates in overdose situations. The system and methods include a wearable device that acquires physiological information from an opioid user during an opioid use session, analyzes the information to detect respiratory depression in the opioid user, and initiates a lifesaving drug injection process when the presence of opioid induced respiratory depression is detected. Several methods are disclosed including self-monitoring and remote monitoring schemes that present a challenge to the opioid user with post injection stimulation of the opioid user and notification of caregivers and medical personnel.
