Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intravenous fluid delivery systems lack the capability for secure, controlled delivery of multiple fluids directly into an IV line, leading to potential medication errors and diversion, and do not allow for compact administration of bolus doses without manual syringe use.
Innovation Solution
An intravenous fluid delivery apparatus with replaceable fluid chambers and a user interface that securely connects to an IV line, featuring a unidirectional bacteriostatic valve and a locking mechanism requiring a passcode for removal, ensuring controlled and precise delivery of multiple fluids while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a syringe pump is used to administer bolus doses, then precise delivery control is achieved, but device length increases substantially due to the plunger requirement
Solution Approach 1:
The patent removes the plunger component from the syringe pump design and replaces it with a roller mechanism that acts on the fluid directly. This extraction of the plunger element eliminates the need for the long syringe barrel while maintaining precise delivery control through the roller's engagement with the fluid reservoir.
Solution Approach 2:
The patent employs a disposable fluid reservoir with an integrated roller mechanism instead of a reusable syringe pump. This disposable approach eliminates the need for a permanent, lengthy plunger structure while providing precise delivery control for the duration of use, after which the entire assembly is discarded.
2Device complexity
If manual syringe administration is used, then device complexity is reduced, but medication errors and diversion risks increase
Solution Approach 1:
The patent implements a self-service system where the fluid reservoir automatically feeds fluid to the roller mechanism, which in turn delivers the fluid through the IV line. This automated self-service loop eliminates manual syringe operations while reducing medication errors through integrated control and monitoring features.
Solution Approach 2:
The patent incorporates feedback mechanisms including flow sensors and control electronics that monitor fluid delivery in real-time. This feedback system detects abnormalities, prevents diversion, and reduces medication errors by ensuring accurate delivery, while the overall system remains relatively simple in design.
3Adaptability or versatility
If multiple fluid chambers are integrated into a single system, then controlled delivery of multiple fluids is achieved, but device complexity increases
Solution Approach 1:
The patent divides the fluid delivery system into separate, modular chambers, each containing a specific fluid. Each chamber has its own roller mechanism and can be independently controlled. This segmentation allows for versatile multi-fluid delivery while keeping each individual module relatively simple and manageable.
Solution Approach 2:
The patent creates a universal platform that can accommodate multiple different fluid chambers using the same basic roller mechanism and control architecture. This multi-functional design enables the system to deliver various fluids through standardized interfaces, reducing overall system complexity despite the ability to handle multiple fluid types.
4Reliability
If secure containment and locking mechanisms are added to prevent diversion, then reliability improves, but device complexity and ease of operation decrease
Solution Approach 1:
The patent implements preliminary security measures where chambers are pre-locked in their receptacles upon insertion. The locking mechanism automatically engages, and the chamber cannot be removed without authorization. This preliminary securing action prevents diversion while maintaining ease of operation during normal use, as the chamber remains securely locked throughout the procedure.
Solution Approach 2:
The patent introduces a passcode or key as an intermediary element between the user and the locking mechanism. This intermediary allows authorized users to easily access chambers when needed while maintaining security against unauthorized removal. The passcode acts as a mediator that simplifies the authentication process without compromising the locking mechanism's effectiveness.
