Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Catheters with built-in optical fibers require easy light intensity confirmation operations while maintaining cleanliness, especially during storage and transportation.
Innovation Solution
A catheter kit design with a hoop that includes a closing part and a transmission window, allowing light intensity confirmation without removing the catheter from the hoop, and a position adjustment mechanism to align the catheter tip end with the hoop tip end for precise measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the catheter is stored in the hoop until immediately before use to maintain cleanliness, then the cleanliness of the catheter is maintained, but the light intensity confirmation operation cannot be performed without removing the catheter from the hoop
Solution Approach 1:
The closing part is divided into a protective section and a transmission window section. The transmission window allows light to pass through while maintaining the closed protective structure of the hoop, enabling light intensity measurement without removing the catheter.
Solution Approach 2:
The transmission window acts as an intermediary element that allows optical signals to pass through the closed hoop structure. It mediates between the need for protection (closed hoop) and the need for light transmission (measurement), enabling both functions simultaneously.
2Ease of operation
If the catheter tip end is exposed for light intensity measurement, then the light intensity confirmation operation can be performed, but the cleanliness of the catheter may be compromised
Solution Approach 1:
The closing part segments the hoop into protected and measurement zones. The transmission window creates a controlled opening that allows light measurement while the rest of the hoop remains closed and protective.
Solution Approach 2:
The closing part has different properties at different locations: it is opaque and protective in most areas, but transparent and open at the transmission window location where light measurement is needed. This local differentiation allows simultaneous protection and measurement.
3Ease of operation
If the catheter is removed from the hoop for light intensity measurement, then the light intensity confirmation operation can be performed, but the risk of contamination increases
Solution Approach 1:
The transmission window serves as an intermediary that enables light measurement without requiring removal of the catheter from the protective hoop. It provides a controlled interface between the sterile catheter environment and the external measurement device.
Solution Approach 2:
The light measurement function is extracted from the catheter itself and performed through the transmission window of the closing part. This allows measurement to be conducted on the catheter while it remains in its protected state within the hoop.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Maintains catheter cleanliness and simplifies light intensity confirmation operations by enabling measurement within the hoop, reducing the risk of contamination and ensuring accurate light intensity readings.
Implementation Method 1
the transmission window is provided at the closing part. Therefore, the light provided from the optical fiber can be obtained in a state in which the catheter is accommodated in the hoop
