Multi-component Delivery System for Surgical Sealants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for mixing and dispensing surgical products, such as tissue adhesives or sealants, are cumbersome and limited in their ability to efficiently mix and deliver multiple components, often requiring tedious procedures and compromising shelf life and effectiveness due to the need for separate packaging and immediate use.
Innovation Solution
A delivery system comprising two assemblies with separate chambers and channels that can be coupled to form communication conduits between them, allowing for the mixing and dispensing of multiple components, with a method involving the movement of the assemblies to align channels for mixing and subsequent dispensing through a mixing nozzle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple components are packaged separately to maintain stability and shelf life, then product stability and shelf life are improved, but the complexity of mixing and delivery procedures increases
Solution Approach 1:
The device divides the delivery system into multiple independent assemblies, each containing specific components in separate chambers. This segmentation allows components to be stored separately for stability while providing an integrated mixing mechanism that reduces procedural complexity.
Solution Approach 2:
The patent combines multiple separate component delivery systems into a single integrated device with a common mixing mechanism. By merging the delivery and mixing functions into one unit, the device reduces the complexity of multiple separate procedures while maintaining component stability through separate packaging.
2Reliability
If components are mixed immediately before application to maintain effectiveness, then product effectiveness is improved, but the time required for mixing and application increases
Solution Approach 1:
The device prepares components for immediate mixing by pre-positioning them in separate chambers with automated delivery mechanisms. This preliminary preparation allows for rapid mixing immediately before application, maintaining product effectiveness while minimizing the time delay between preparation and application.
Solution Approach 2:
The mixing mechanism is designed to operate continuously and automatically once activated, ensuring that components are mixed immediately and consistently without interruption. This continuous action eliminates delays and ensures product effectiveness is maintained from mixing through application.
3Ease of operation
If traditional mixing methods are used to mix components from separate syringes, then component mixing is achieved, but the procedure becomes tedious and time-consuming
Solution Approach 1:
The device incorporates automated delivery mechanisms that automatically transfer components from their storage chambers to the mixing point without requiring manual manipulation. This self-service capability eliminates tedious manual mixing procedures and significantly reduces the time required to prepare the final mixture.
Solution Approach 2:
The patent replaces manual mechanical mixing operations with an automated mixing mechanism that uses controlled fluid delivery and mixing chambers. This substitution of manual mechanical operations with an automated system eliminates tedious procedures and reduces mixing time while maintaining mixing effectiveness.
