Infusion Set Organizer With Electronic Drip Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of multiple infusion sets during vascular interventions leads to a messy operation table, difficulty in distinguishing between sets, and challenges in adjusting drip rates, which increases the risk of pulmonary edema and vascular embolism due to manual control and lack of clear observation.
Innovation Solution
An infusion set auxiliary device with a bottom plate and fixing seat featuring sequentially arranged fixing holes, light-transmitting holes, and electronic drip rate control, along with detectors and alarms, to organize and monitor infusion sets, ensuring clear marking, orderly arrangement, and automatic rate adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple infusion sets are used to flush catheters, then the risk of intraductal thrombosis and distal vascular embolization is reduced, but the operation table becomes messy and the infusion sets become difficult to distinguish
Solution Approach 1:
The patent divides the monitoring and control function into separate modular components: individual drip rate controllers for each infusion set, separate fixing seats for organizing multiple sets, and distinct labeling systems. This segmentation allows each infusion set to be independently managed while maintaining overall system organization.
Solution Approach 2:
The patent introduces intermediary organizing structures such as fixing seats and mounting boards that serve as mediators between the multiple infusion sets and the operator. These intermediaries provide a structured framework that holds and arranges the infusion sets, making them easier to distinguish and manage without directly altering the infusion sets themselves.
2Productivity
If multiple infusion sets are suspended on the infusion rack, then all catheters can be flushed simultaneously, but some drip pots are blocked by other infusion tubes and drip pots making observation difficult
Solution Approach 1:
The patent transitions from a two-dimensional arrangement where drip pots are stacked or closely positioned on the infusion rack to a three-dimensional configuration using vertical mounting boards and elevated fixing seats. This dimensional change spaces out the drip pots in both vertical and horizontal directions, eliminating blocking issues while maintaining simultaneous flushing capability.
Solution Approach 2:
The patent employs nested structures where fixing seats are integrated into mounting boards, and drip pots are positioned within designated slots on the mounting board. This nesting approach allows multiple infusion sets to be organized in a compact yet accessible manner, with each drip pot having its own designated space that prevents blocking by adjacent sets.
3Ease of operation
If manual drip rate control is used, then the operator can adjust the drip rate, but the drip rate is subjectively estimated and may lead to pulmonary edema or intraductal thrombosis
Solution Approach 1:
The patent replaces the purely mechanical manual adjustment system with an integrated electronic control system that includes electronic drip rate controllers, sensors for monitoring fluid flow, and automated adjustment mechanisms. This substitution maintains the ease of operation through user-friendly interfaces while dramatically improving drip rate accuracy through electronic precision control and real-time monitoring.
Solution Approach 2:
The patent incorporates feedback mechanisms where sensors continuously monitor the actual drip rate and fluid flow, and this information is fed back to the control system. The control system then automatically adjusts the drip rate to match the prescribed parameters, ensuring accurate and reliable fluid administration while allowing operators to make adjustments through simple interface interactions.

AI summary
An infusion set auxiliary device and an infusion set system for vascular intervention are provided. A fixing seat is convex on a bottom plate and has a top surface, a bottom surface and a side surface which is opposite to the bottom plate. The fixing seat includes a plurality of fixing holes arranged along a first direction, and each fixing hole is used for holding a drip pot of one infusion set. The fixing hole penetrates through the side surface, the top surface and the bottom surface to form a first opening, a second opening and a third opening respectively, the sizes of the first opening, the second opening and the third opening satisfy corresponding relationships with the outside diameter of the infusion tube and the outside diameter of the drip pot. The application can arrange multiple infusion sets neatly to facilitate differentiation.
