Multi-Interface Syringe for Cement Mixing and Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for mixing and delivering cement to treat bone or hard tissue are cumbersome, expose practitioners to unpleasant odors, and require significant force, especially when dealing with high-viscosity cements, which can obscure imaging sites and expose practitioners to radiation.
Innovation Solution
A multi-interface syringe system that allows for the aspiration and delivery of cement from a mixing vessel to a hard tissue using a pressure delivery device, incorporating a high-pressure syringe with an internal mixing apparatus to mix cement within the syringe, reducing exposure and facilitating distant delivery through a swivel elbow and flexible tubing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mixing and delivery methods are used, then cement can be delivered to treat bone or hard tissue, but the process is cumbersome and requires significant force especially for high-viscosity cements
Solution Approach 1:
The system divides the cement delivery process into separate functional components: a mixing vessel for preparation, a syringe for storage and delivery, and a pressure delivery device for injection. This segmentation allows each component to be optimized independently, with the syringe designed to handle high-viscosity materials through controlled pressure application rather than manual force.
Solution Approach 2:
The pressure delivery device utilizes pneumatic or hydraulic principles to generate controlled pressure that forces the high-viscosity cement through the syringe and delivery catheter. This mechanical advantage reduces the effort required by the practitioner compared to direct manual injection, allowing smooth delivery of thick cement materials.
2Measurement precision
If practitioner is positioned close to imaging site for delivery, then delivery precision is improved, but radiation exposure to practitioner increases
Solution Approach 1:
The flexible tubing acts as an intermediary element that decouples the practitioner's position from the imaging site. The practitioner can operate the pressure delivery device at a safe distance while the cement is delivered through the flexible tubing to the target area, maintaining delivery precision while reducing radiation exposure through spatial separation.
3Manufacturing precision
If cement is mixed in a separate vessel and then transferred, then mixing quality is improved, but the process becomes more complex and time-consuming
Solution Approach 1:
The system merges the mixing and delivery functions into an integrated workflow where the mixing vessel is directly coupled to the syringe. This eliminates the need for separate transfer steps while maintaining mixing quality, as the cement can be directly aspirated from the mixing vessel into the syringe through a connected interface, reducing overall process complexity.
4Ease of operation
If practitioner handles cement directly, then delivery control is improved, but exposure to unpleasant odors increases
Solution Approach 1:
The syringe serves as an intermediary that contains the cement throughout the delivery process. The cement remains enclosed within the sealed syringe barrel, preventing odor release to the practitioner while allowing controlled delivery through the plunger mechanism. This isolation maintains delivery control without exposing the practitioner to unpleasant odors.

AI summary
The present disclosure relates to systems and methods for mixing and injecting fluid treatment, such as cement to treat bone or hard tissue. In some embodiments, a mixing apparatus may facilitate mixing within a syringe. Additionally, the syringe may be configured to extract bone cement from a cement mixer. A syringe for mixing and injecting cement may include a detachable handle that may be detached after extracting bone cement from a mixer to facilitate coupling to a high-pressure syringe for injection.
