Solution Overview

Problem

Existing puncture systems face challenges in easily switching the display mode of blood vessel visualized images, as operating a switch on a blood vessel visualization device while gripping a puncture tool is cumbersome.

Innovation Solution

A puncture system with a blood vessel visualization device that acquires a marker state in a puncture tool, such as an indwelling needle, to specify the display mode of a blood vessel visualized image based on the marker's state, including size, color, brightness, or contrast, using near-infrared light emission and imaging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a switch on the blood vessel visualization device is operated to switch display mode, then the display mode can be switched, but it becomes difficult to perform the switch operation while gripping a puncture tool

Engineering Contradiction:
Improveease of switching display modeVSAvoidoperation complexity during puncture
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a marker on the puncture tool as an intermediary element. The marker's state (position, orientation, or presence) serves as a mediator to communicate the operator's intended display mode preference to the visualization device, eliminating the need for direct switch operation while holding the tool.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical switch operation with an optical/detection-based system. The marker state is detected by the visualization device through imaging or sensing mechanisms, substituting the manual mechanical switching action with an automated detection and response system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Illumination intensity

If the blood vessel visualized image is displayed during puncture, then visibility is improved, but it becomes difficult to observe skin deformation and other visual cues

Engineering Contradiction:
Improvevisibility of blood vesselVSAvoidloss of skin deformation information
Core Design Contradiction:
Illumination intensityVSLoss of information

Solution Approach 1:

The patent implements dynamic switching of the display mode based on the marker state. The system adapts between displaying the blood vessel visualized image and not displaying it, depending on the operator's needs indicated by the marker, allowing optimal visibility conditions for different procedural phases.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the display parameter (displayed or not displayed) based on the marker state. This parameter change allows the system to switch between providing enhanced blood vessel visibility and preserving natural skin observation, resolving the information loss conflict.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If manual switching of display mode is required, then display control is precise, but it increases the time and steps required for mode switching

Engineering Contradiction:
Improvedisplay mode control precisionVSAvoidtime for mode switching
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs self-service by automatically determining the appropriate display mode based on the marker state without requiring manual intervention. The visualization device autonomously adjusts its display output based on the detected marker configuration, eliminating time-consuming manual switching while maintaining reliable control.

Inventive Principle:
Principle #25Self-service
