Catheter Light Source Positioning for Opening Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing catheter technologies lack effective methods for easily identifying the position of the catheter opening within the body, which can lead to improper placement and complications such as aspiration pneumonia.
Innovation Solution
Incorporating light sources into the catheter or guide wire, which are photographed by a unit outside the body, allowing for accurate identification of the catheter opening position through image processing and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light is introduced through a catheter or optical fiber from a light source outside the body, then light loss is large, light diffusivity is low, and the amount of light is insufficient, but introducing light sources into the catheter enables accurate identification of the catheter opening position
Solution Approach 1:
The patent uses light sources as intermediaries embedded within the catheter structure to transmit position information. These light sources act as mediators between the catheter opening and the external photographing unit, enabling accurate position identification without requiring light to travel through the entire catheter length from an external source, thereby reducing light loss and improving identification accuracy.
Solution Approach 2:
The patent replaces the conventional mechanical/electrical position identification methods (such as electrodes or magnetic sensors) with an optical system. By embedding light sources in the catheter and using a photographing unit to capture their positions, the system substitutes mechanical positioning mechanisms with an optical field-based approach, enabling more accurate and visual position identification.
2Measurement precision
If conventional position identification methods (electrodes, magnetic sensors) are used, then the catheter can be positioned, but the opening position cannot be easily identified
Solution Approach 1:
The patent extracts the position identification function from the catheter structure itself and separates it into distinct components: light sources embedded in the catheter, a photographing unit outside the body, and image processing systems. This extraction allows the catheter to maintain its primary function while enabling precise opening position identification through the external optical system, reducing the complexity of integrated positioning mechanisms.
Solution Approach 2:
The patent utilizes optical properties (light emission and detection) to identify the catheter opening position. By embedding light sources that emit visible or detectable light, the system creates optical signatures that can be captured and processed to determine position, replacing complex mechanical or electrical sensing systems with a simpler optical detection approach.
3Ease of operation
If light sources are embedded in the catheter, then the opening position can be visually identified, but the catheter structure becomes more complex
Solution Approach 1:
The patent integrates light sources into the catheter structure, enabling the catheter to serve multiple functions: its primary function for fluid introduction/removal and the additional function of position identification. By making the catheter multi-functional, the system avoids adding separate positioning devices, thereby managing complexity while improving ease of operation through visual position identification.
