Syringe Stabilizing Element for Multi-Use Disposable Set Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-fluid delivery systems face challenges in maintaining the stable positioning of syringes within the injector system, leading to potential fluid leakage, breakage, or damage due to applied forces during injection procedures.
Innovation Solution
A multi-use disposable set and syringe configuration with a stabilizing element on the distal end, featuring a support surface extending perpendicular to the longitudinal axis, which includes a ring, sleeve, or planar portions with webs, to prevent off-center or angled positioning and ensure secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If force is applied to the syringe during fluid delivery or engagement, then fluid delivery function is achieved, but the syringe may be pushed or dislodge into an off-center, tilted, or angled position causing fluid leakage, breakage, or damage
Solution Approach 1:
The stabilizing element is pre-configured on the syringe body before insertion into the fluid injector. This preliminary structural arrangement ensures that when force is applied during fluid delivery or engagement, the syringe is already positioned to resist off-center or tilted positioning, preventing fluid leakage, breakage, or damage before these harmful effects can occur.
Solution Approach 2:
The stabilizing element acts as an intermediary component between the syringe body and the fluid injector. It mediates the interaction by providing a support surface that distributes applied forces evenly, preventing direct transmission of destabilizing forces to the syringe contents and preventing harmful effects like fluid leakage or breakage.
2Ease of operation
If the syringe is positioned off-center, tilted, or angled within the fluid delivery system, then insertion may be easier, but fluid leakage around the plunger, breakage of the syringe, or damage to the fluid injector assembly occurs
Solution Approach 1:
The stabilizing element on the syringe body provides self-alignment capabilities during insertion into the fluid injector. The support surface automatically guides the syringe into the correct centered position without requiring external alignment tools or complex insertion mechanisms, making the insertion process easy while simultaneously ensuring proper positioning to prevent fluid leakage and breakage.
3Reliability
If a stabilizing element with support surface is added to the syringe, then syringe alignment and positioning stability are improved, but device complexity increases
Solution Approach 1:
The stabilizing element is merged with the syringe body as an integrated component rather than a separate attachment. This combining of functions reduces the number of discrete parts, simplifies assembly, and lowers device complexity while still providing the necessary alignment and positioning stability to prevent fluid leakage and breakage.
Solution Approach 2:
The stabilizing element serves multiple functions simultaneously: it provides structural support, ensures proper alignment, distributes applied forces, and prevents off-center positioning. This multi-functionality means that a single component addresses multiple positioning challenges without requiring additional separate elements, thereby avoiding increased device complexity.
