Solution Overview

Problem

Colonic diverticula often present multiple bleeding sites, making it difficult to specify and treat the bleeding points endoscopically, especially when large numbers are involved, and existing methods struggle to deliver medicine effectively to multiple affected areas simultaneously.

Innovation Solution

A treatment method involving a device with inflatable balloons that close a tubular organ, aspirate gas, and deliver medicine to the affected area, creating a controlled environment to suppress bleeding across multiple diverticula without needing to identify each bleeding point individually.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If endoscopic observation is used to identify bleeding points, then individual treatment can be performed, but it becomes difficult to specify bleeding points when large numbers of diverticula are present

Engineering Contradiction:
Improvebleeding point identification accuracyVSAvoidtreatment system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The treatment system segments the tubular organ into multiple isolated sections using first and second closures (balloons or clamps) to create separate closed spaces. This allows independent treatment of each segment containing diverticula, making it feasible to treat multiple affected areas without needing to identify every single bleeding point throughout the entire organ.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies partial action by treating only the specific closed space containing the diverticula rather than attempting to treat the entire tubular organ. By delivering liquid medicine (such as ethanol) into the isolated closed space, the treatment effectively addresses the affected area without requiring comprehensive identification of all potential bleeding points in the whole organ.

Inventive Principle:
Principle #16Partial or excessive action

2Productivity

If medicine is delivered to multiple affected sites simultaneously, then treatment efficiency is improved, but it is difficult to ensure effective medicine delivery to all areas without specifying each bleeding point

Engineering Contradiction:
Improvetreatment efficiencyVSAvoidmedicine delivery precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The closed space created by the first and second closures is further segmented into multiple treatment regions using additional closures or barriers. This segmentation ensures that liquid medicine delivered into the closed space is distributed to multiple affected sites simultaneously while maintaining sufficient concentration in each region, achieving both high productivity and effective medicine delivery without needing to identify every bleeding point.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system delivers liquid medicine in excess to the closed space containing multiple diverticula, ensuring that all affected sites within that space receive adequate treatment. This approach prioritizes treating the entire closed space rather than precisely targeting each individual bleeding point, thereby improving treatment efficiency while maintaining effectiveness.

Inventive Principle:
Principle #16Partial or excessive action

3Quantity of substance

If the tubular organ is closed to create a closed space for medicine delivery, then medicine can be concentrated at the affected site, but gas in the organ must be removed to create effective negative pressure

Engineering Contradiction:
Improvemedicine concentration at affected siteVSAvoidclosed space creation complexity
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The system performs preliminary action by first closing the tubular organ with the first and second closures and then removing gas from the closed space before delivering liquid medicine. This sequence creates negative pressure within the closed space, which facilitates subsequent medicine delivery and ensures concentrated distribution to the affected diverticula. The gas removal step is performed in advance to prepare the closed space for effective medicine concentration.

Inventive Principle:
Principle #10Preliminary action
