Threadless Syringe Spray Delivery for Sinus Biomaterials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-component biomaterial systems for sinusitis treatment face challenges with rapid reaction times, leading to erratic performance and the need for a spray application that forms a gel or solid quickly, while also requiring single-handed operation and unthreaded syringe engagement for ease of use.
Innovation Solution
A spray delivery system comprising a body with syringe-receiving and finger grip portions, an actuating member for simultaneous syringe content delivery, a manifold for liquid content reception, and a spray head, allowing for unthreaded syringe engagement and easy assembly, enabling the delivery of separate components that mix just before application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-component biomaterial systems are used for sinusitis treatment, then the treatment effectiveness is improved, but the reaction time becomes too rapid causing erratic performance
Solution Approach 1:
The system divides the biomaterial into separate components stored in individual syringes, which are delivered separately through the delivery device and only mixed at the point of application. This segmentation prevents premature reaction while enabling controlled mixing when needed for treatment.
Solution Approach 2:
The delivery device acts as an intermediary system that maintains component separation during storage and transport, then facilitates controlled mixing at the application site. The device includes separate channels for each component and a mixing chamber where they combine just before delivery to the sinus cavity.
2Speed
If components are mixed rapidly for quick gel formation, then the spray application speed is improved, but the performance becomes erratic and unreliable
Solution Approach 1:
The system prepares components separately in advance during storage and transport, maintaining them in a ready-to-deliver state without premature mixing. The components are pre-loaded into the delivery device and can be delivered immediately when needed, achieving both speed and reliability.
Solution Approach 2:
The system skips the mixing step during storage and transport phases, rushing only the delivery phase. Components are delivered quickly through separate channels and mixed only at the critical moment of application, ensuring both rapid deployment and consistent performance.
3Reliability
If threaded engagement is used for syringe connection, then the connection reliability is improved, but the assembly complexity and time increase
Solution Approach 1:
The system replaces complex threaded mechanical connections with a simpler bayonet-style quick-connect mechanism. This substitution maintains secure, reliable connections while dramatically reducing assembly complexity and time, allowing single-handed operation.
Solution Approach 2:
The connection mechanism changes the engagement parameters from rotational threading to a click-style bayonet connection with defined engagement positions. This parameter change maintains connection reliability through positive locking while simplifying the assembly process to require minimal motion and force.
4Strength
If traditional packing techniques are used for post-operative care, then the sinus passage support is improved, but the patient comfort and ease of removal deteriorate
Solution Approach 1:
The system uses biomaterials that undergo phase transition from liquid to gel or solid form after delivery. The material is delivered as a liquid through spray application, then transforms into a gel or solid that provides sinus passage support, eliminating the need for traditional gauze packing and associated discomfort.
