Self-Administered Migraine Medication Applicator with Safety Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for administering local anesthetics, such as lidocaine, to the sphenopalatine ganglion for migraine relief require the assistance of a trained medical professional and are typically done while the patient is in a supine position.
Innovation Solution
A device designed for self-administration of medication, which includes a medication applicator that dispenses a medication as an aerosol mist directly to the sphenopalatine ganglion, an activator for releasing the medication in two doses, and a safety interlock to prevent premature dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cotton swab applicator with viscous local anesthetic is used, then the medication can be applied to the sphenopalatine ganglion, but the procedure requires assistance or supervision of a trained medical professional
Solution Approach 1:
The device enables self-service by allowing patients to administer the medication themselves through a self-contained applicator system with pre-loaded medication reservoir and automated delivery mechanism, eliminating the need for medical professional assistance
Solution Approach 2:
The invention replaces the manual mechanical application method (cotton swab) with an automated mechanical system that includes a motorized pump, controlled dispensing mechanism, and integrated applicator, ensuring precise and safe dosing without requiring medical training
2Ease of operation
If the patient lies in a supine position during administration, then the medication can be effectively applied, but the procedure becomes more complex and time-consuming
Solution Approach 1:
The device incorporates dynamic positioning capabilities with an adjustable applicator arm and flexible delivery mechanism that can adapt to different patient positions, allowing effective medication delivery whether the patient is supine, sitting, or standing
3Device complexity
If a single-dose applicator is used, then the device is simpler, but it cannot provide controlled sequential dosing
Solution Approach 1:
The medication delivery system is segmented into multiple discrete dosing units within a single applicator, with each unit capable of independent activation, allowing controlled sequential dosing while maintaining a unified device structure
Solution Approach 2:
The device implements periodic action through timed intervals between dose dispensing, with automated control mechanisms that regulate the timing and sequence of multiple doses to optimize therapeutic effect while preventing premature administration
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 self-administration of medication in an upright position, allowing for more convenient and independent management of migraine pain while ensuring safe and controlled dosing.
Implementation Method 1
The medication applicator may store a medication and may dispense the medication as an aerosol mist

AI summary
The device for dispensing medication for migraine treatment may comprise a medication applicator, an activator, and a safety interlock. The medication applicator may store a medication and may dispense the medication as an aerosol mist. The medication applicator may be adapted to dispense the medication through a nostril of a user directed at a sphenopalatine ganglion. The activator may be operable to release the medication in two doses—a first dose may be dispensed upon the activation of a first button and a second dose may be dispensed upon the activation of a second button. The safety interlock may prevent premature dispensing of the medication and may constrain dispensing such that the first dose must be dispensed before the second dose. The invention may be adapted for the user to self-administer the medication while the user is upright.
