Bone Cement Fluid Reservoir for Staggered Syringe Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone cement preparation methods require mixing two components just before use, leading to time constraints and inconsistent rheological properties across multiple syringes, limiting surgical flexibility and increasing waste.
Innovation Solution
A device and system for providing bone cement paste from two starting components, allowing for staggered mixing and use of multiple syringes from a single container, ensuring consistent properties and extended working time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large quantity of bone cement is supplied in a single container to fill multiple syringes, then the quantity of substance is improved, but the processing time begins simultaneously for all syringes placing the surgeon under time pressure and limiting flexibility
Solution Approach 1:
The single container of bone cement is divided into multiple separate containers, each sufficient to fill one syringe. This segmentation allows each syringe to be prepared independently with its own processing time window, eliminating the time pressure that would result from preparing all syringes simultaneously from a single mixed batch.
2Quantity of substance
If bone cement paste is prepared for multiple syringes simultaneously, then the quantity of substance is improved, but the rheological properties differ across syringes complicating the procedure
Solution Approach 1:
The bone cement is supplied in multiple separate containers rather than one large mixed batch. This ensures that each syringe receives freshly mixed paste with consistent rheological properties, as each container represents a separate mixing event that occurs closer to the time of use.
Solution Approach 2:
Multiple containers of bone cement are prepared in advance, each ready to fill one syringe. This preliminary preparation of multiple identical units ensures that when syringes are filled, they all receive paste with the same rheological properties, eliminating variability that would arise from a single large batch that sits while other syringes are used.
3Duration of action of moving object
If fast-setting bone cement is used to reduce processing time, then the duration of action is improved, but the surgeon has even less time to complete the procedure
Solution Approach 1:
The bone cement is divided into multiple separate containers, each capable of filling one syringe. This allows the surgeon to work with one syringe at a time, using fast-setting cement efficiently for each individual procedure without the pressure of having to use multiple syringes simultaneously before the cement hardens.
