Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infusion sets face challenges such as leakage during priming, contamination risks, complexity in procedural discharge, misidentification of infusion containers, and accidents due to twisting or movement of the IV stand, leading to patient discomfort and increased stress for medical personnel.
Innovation Solution
An infusion set design that allows for separate priming of primary and secondary tubing without contamination, featuring hydrophobic filters and clip-equipped caps to prevent leakage, and color-coded three-way stopcocks to simplify administration order recognition, along with packaging illustrations to aid in procedure standardization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional infusion sets are used for priming operations, then priming can be performed, but leakage of infusion liquid may occur from the needle tip during priming
Solution Approach 1:
The infusion set is divided into multiple independent priming flow paths (first priming flow path and second priming flow path) with separate control mechanisms. This segmentation allows selective priming of different pathways, enabling the system to perform priming operations while controlling liquid flow to prevent leakage from the needle tip.
Solution Approach 2:
A shutoff clamp is introduced as an intermediary control device positioned below the drip chamber. This clamp acts as a mediator to regulate and stop liquid flow at a critical point in the system, preventing uncontrolled leakage during priming operations while allowing normal infusion when opened.
2Ease of operation
If the infusion set structure allows terminal portions to be open for priming, then priming can be performed, but contamination of hospital environment may occur
Solution Approach 1:
The priming system is segmented into multiple controlled flow paths with dedicated shutoff clamps. This segmentation creates isolated priming zones that can be sealed off from the external environment, allowing priming to be performed without exposing open terminals that could contaminate the hospital room.
Solution Approach 2:
The harmful aspect of open terminals is addressed by extracting the priming function into separate, controlled flow paths. The system separates the priming operation from the main infusion pathway, confining potential contamination risks to isolated segments that can be controlled and sealed independently.
3Reliability
If multiple priming steps are required with flow path switching, then complete priming can be achieved, but procedural complexity increases
Solution Approach 1:
The priming procedure is segmented into distinct flow paths with dedicated control clamps for each path. This segmentation simplifies the overall procedure by allowing systematic priming of each segment independently, reducing the complexity of coordinating multiple switching operations while ensuring complete priming coverage.
Solution Approach 2:
Each priming flow path is equipped with its own shutoff clamp and control mechanism, enabling self-contained priming operations. This self-service design allows operators to prime each path independently without complex coordination, reducing procedural complexity while maintaining reliability.
4Ease of operation
If physiological saline solution is discharged during priming, then priming can be completed, but damage to equipment and contamination may occur
Solution Approach 1:
Shutoff clamps are positioned as intermediary control devices at strategic locations below the drip chamber. These clamps serve as mediators to intercept and control liquid flow, preventing uncontrolled discharge of physiological saline solution that could damage equipment or cause contamination while allowing necessary liquid flow for priming.
Solution Approach 2:
The shutoff clamps are pre-positioned in the system to provide preliminary control over liquid flow before discharge can occur. This preliminary anti-action mechanism prevents harmful liquid discharge by establishing control points that can stop flow in advance, protecting equipment and environment from potential damage.

AI summary
The present invention provides a novel infusion set which is an infusion set comprising first member(s) constituting primary tubing and second member(s) constituting instant tubing, and at which there is covering by a cap, arranged at which there is an opening configured so as to not allow passage therethrough of solid or liquid but so as to allow passage therethrough of gas at the interior of the cap, a hydrophobic filter being arranged at a location inward from where the tip of a connector for connection with a three-way stopcock or a connector for connection with an intravenous drip needle is inserted at the interior of the cap by way of an insertion port, and a lid at the exterior of said opening for closing said opening, as a result of which it is possible to carry out priming by means of a simple operation without leakage of liquid; and in which ease of operations is improved due to the fact that first member(s) and second member(s) can be connected as desired by three-way stopcock(s) 5; coloring optionally being applied thereto; and it is possible to maintain stability of the infusion set and IV stand, to prevent bodily pain to patients and leakage of liquid at locations where intravenous needles are inserted, and to prevent occurrence of accidents due to human error with regard to administration procedures, and which makes it possible to easily establish standard procedures for use.
