Nasal Injector Connector with Locking Interface for SPG Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for treating pain associated with headaches and facial aches are not safe or effective, particularly due to the limitations of NSAIDs, narcotics, and SPG block procedures, which often require medical supervision and can be inefficient or risky due to incorrect anatomical targeting.
Innovation Solution
A connector system with a single-use locking interface and a device design that allows for secure, fluid-patent communication to deliver medicaments directly to the sphenopalatine ganglion, enabling safe and effective SPG block without medical supervision, using a luer-lock internal connection and a tooth/notch outer connection to prevent counter-rotation, and a deformable stop bar for single-use functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional SPG block procedures are used with cotton-tipped applicators, then medical supervision is required and the procedure is complex, but the safety and effectiveness are compromised due to blind advancement and incorrect anatomical targeting
Solution Approach 1:
The device is divided into distinct functional components: an introducer with anatomical guidance features, a syringe for medicament delivery, and a connector system. This segmentation allows each component to perform its specific function optimally while simplifying the overall procedure and enabling self-administration without medical supervision
Solution Approach 2:
The introducer is pre-configured with anatomical guidance features and stop bars that automatically position the syringe tip at the correct anatomical location before medicament injection. This preliminary positioning action eliminates the need for blind advancement and ensures accurate targeting of the sphenopalatine ganglion, improving safety and effectiveness while reducing procedure complexity
2Ease of operation
If NSAIDs are used for pain management, then they are widely available and easy to use, but they cause ulcers and heart attacks and are ineffective in many patients
Solution Approach 1:
The device uses local anesthetic medicament as an intermediary substance that directly blocks nerve transmission at the sphenopalatine ganglion, providing pain relief without the systemic side effects of NSAIDs. This intermediary approach allows patients to self-administer effective pain management without exposing themselves to harmful effects like ulcers and heart attacks
3Reliability
If narcotics are used for pain relief, then they provide strong analgesic effects, but they have potentially addictive properties
Solution Approach 1:
The device employs a disposable single-use syringe and connector system that delivers a precise, limited dose of local anesthetic. This disposable approach ensures the medicament is used only once and then discarded, eliminating the risk of addiction associated with narcotics while providing reliable pain relief through localized nerve blockade rather than systemic opioid effects

AI summary
A method and device for delivering medicament such as for ameliorating pain in a patient from an injector superiorly and/or laterally and/or anteriorly towards the sphenopalatine ganglion (SPG). A device for delivering a medicament to a patient in need thereof includes (a) an injector containing a first end configured to remain outside a nasal passage of the patient and a second end configured for entry into the nasal passage of the patient; and (b) an introducer configured for engagement with a nostril of the patient and containing a passageway configured for slidably receiving the injector. The injector is moveable between a storage position preceding the engagement and an engaging position pursuant to the engagement. The device may further include a locking connection assembly that is useful in other devices.
