Wearable Opioid Overdose Detection and Automated Antidote Injection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable systems for monitoring vital signs fail to promptly administer an opioid antidote during an overdose, resulting in delayed emergency response and potential loss of life due to the time gap between overdose detection and antidote administration.
Innovation Solution
A wearable system that combines a monitor unit for detecting opioid overdose symptoms with a solenoid-actuated injector unit, which automatically injects a prescribed dosage of opioid antidote upon detecting depressed heart rate, respiration rate, and elevated blood CO2 levels, transmitting distress messages with GPS coordinates to emergency responders and activating a solenoid to insert and retract a hypodermic needle for antidote delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a wearable GPS device monitors vital signs to detect opioid overdose, then overdose detection capability is improved, but response time is too long for emergency responders to reach the subject
Solution Approach 1:
The system performs preliminary action by automatically injecting the opioid antidote upon detection of overdose conditions, before emergency responders can arrive. The wearable device detects depressed respiratory and heart rates indicative of overdose, then immediately activates the injection mechanism, eliminating the dangerous delay between detection and treatment.
Solution Approach 2:
The system enables self-service by allowing the wearer to receive automated antidote injection without human intervention. The wearable device autonomously monitors vital signs, detects overdose conditions, and administers treatment through an automated injection mechanism, making the system self-sufficient for emergency response.
2Speed
If a wearable system combines monitor unit with automated injector unit, then response speed is improved, but device complexity increases
Solution Approach 1:
The system merges the monitor unit and injector unit into a single integrated wearable device. The monitor unit tracks vital signs while the injector unit contains the antidote and injection mechanism; both units communicate and coordinate within the same device housing, enabling seamless automated response while consolidating components.
Solution Approach 2:
The wearable device performs multiple functions within a single system: continuous vital sign monitoring, overdose detection algorithm execution, automated antidote injection, and GPS tracking. This multi-functionality allows the device to serve as both a health monitor and an emergency response system, improving response speed while sharing common components.
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
Enables rapid and automated administration of an opioid antidote, potentially saving lives by reducing the time gap between overdose detection and treatment, as the system quickly injects the antidote into the wearer's body upon detecting life-threatening vital sign deviations.
Implementation Method 1
the system energizes a solenoid. Upon activation, the armature of the solenoid retracts into the solenoid coil
Implementation Method 2
it opens a latch to release a spring-loaded plunger within a syringe assembly containing a syringe loaded with a prescribed dosage of an opioid antidote. The plunger springs contract, depressing the syringe plunger so as to force the antidote
Implementation Method 3
causing the return spring to extract the armature from the solenoid coil. The extracted armature pulls the needle carriage back, so as to withdraw the needle from the wearer's body
Data Source
AI summary
A wearable system detects an opioid overdose and transmits a distress message with the wearer's GPS coordinates to one or more emergency response contacts. Concurrently, the system signals a switch which energizes a solenoid injector, causing a prescribed dosage of an opioid antidote to be injected by a syringe into the wearer's body. Detection of an opioid overdose is based on one or more symptomatic biometrics, which are measured by a wearable monitor. The monitor unit and the injector units can be separate, or they can be combined in a single unit.
