Solution Overview

Problem

Patients with stomas created due to conditions like diverticulitis, rectal cancer, or inflammatory bowel diseases face challenges with interrupted intestinal function, inadequate nutrient absorption, and increased suffering due to the need for parenteral nutrition, as well as complications from long-term hospitalization and reduced quality of life.

Innovation Solution

A device comprising pump forming means with entry and exit openings, connected to stomas via watertight connections, allowing food bolus to circulate between two stomas outside the body, eliminating the need for surgical implantation and reducing infection risks, and enabling better nutrient absorption by preserving intestinal functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a device is surgically implanted to circulate food bolus, then intestinal function can be restored, but infection risk increases and surgical complications occur

Engineering Contradiction:
Improveintestinal function restorationVSAvoidinfection risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses an external pump device as an intermediary between the two stomas, connected via waterproof connectors that interface with the stoma openings. This mediator enables food bolus circulation without requiring internal surgical implantation, thus restoring intestinal function while avoiding the infection risks and complications associated with implanted devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If parenteral nutrition is used for long term, then nutrient absorption is maintained, but hospitalization costs increase and quality of life decreases

Engineering Contradiction:
Improvenutrient absorptionVSAvoidhospitalization requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The external pump device enables patients to autonomously circulate food bolus between stomas at home without requiring hospitalization or parenteral nutrition support. The device allows natural digestion and absorption processes to continue, empowering patients to manage their own nutrition independently, thereby reducing healthcare costs and improving quality of life.

Inventive Principle:
Principle #25Self-service

3Reliability

If stomas are created to treat bowel conditions, then life-saving treatment is achieved, but quality of life and digestive function are compromised

Engineering Contradiction:
Improvelife-saving treatmentVSAvoidquality of life
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a dynamic external pump system that can be activated and deactivated as needed, allowing flexible control over food bolus circulation. This dynamic approach enables patients to maintain normal digestive function when the pump is operating while preserving the life-saving stoma configuration, thus improving quality of life without compromising the essential treatment.

Inventive Principle:
Principle #15Dynamics

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

The device improves the quality of life for patients by allowing food bolus circulation without surgical intervention, reducing the need for parenteral nutrition, and maintaining intestinal function, while being portable and non-restrictive, thus enhancing convalescence and reducing hospitalization costs.

AI summary

A device enabling food bolus flow between two stomas, said device having a pump forming means (3), said pump forming means (3) having an entry opening and an exit opening and being suitable for sucking food bolus through said entry opening and releasing it through said exit opening. The device further includes: —first watertight connection means (11) suitable for connecting said entry opening to a upstream stoma (S1) located on a patient's abdominal wall; —second watertight connection means (1) suitable for connecting said exit opening to a downstream stoma (S2), located on said patient's abdominal wall; said pump forming means being able to be activated by a user and suitable for being mounted on a patient's body, particularly on said patient's abdomen, in such a manner that once said device is mounted onto said patient's abdomen, food bolus flow can circulate from said upstream stoma (S1) to said downstream stoma (S2) outside of said patient's abdomen.
