Fecal Bypass Tube with Pressure Relief for Intestinal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fecal bypass apparatuses cause abdominal pain and damage to the intestinal lining due to increased intestinal pressure and peristalsis, leading to complications and a deterioration in patients' quality of life.
Innovation Solution
An auxiliary apparatus for fecal bypass with a main body part, supporting portions, and a blocking part that expands to fix to the intestine, allowing a liquid moving tube to adjust pressure and facilitate the discharge of treatment liquid, reducing abdominal pain and preventing intestinal damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the auxiliary apparatus for fecal bypass closes the inside of the intestine to bypass feces, then the anastomotic site is protected from fecal leakage, but the intra-intestinal pressure increases causing abdominal pain
Solution Approach 1:
The intestine is divided into two separate pathways: a closed segment through the auxiliary apparatus for fecal bypass that protects the anastomotic site, and an open segment through the liquid moving tube that allows pressure relief. This segmentation enables simultaneous protection and pressure management.
Solution Approach 2:
The liquid moving tube acts as an intermediary pressure relief mechanism. It provides a controlled pathway for liquid to escape, mediating between the closed intestinal segment and the pressure buildup, thereby preventing abdominal pain while maintaining anastomotic protection.
2Stability of the object's composition
If the auxiliary apparatus for fecal bypass is fixed to the intestine with a band, then the apparatus remains in position, but the inner wall of the intestine is damaged due to increased internal pressure
Solution Approach 1:
The liquid moving tube serves as a pressure relief intermediary that prevents excessive internal pressure from damaging the intestinal lining. By providing an escape route for liquid, it protects the band-apparatus-intestine system from pressure-induced damage while maintaining stable positioning.
Solution Approach 2:
The liquid moving tube provides beforehand cushioning by preparing a pressure relief pathway before damage occurs. This preventive mechanism cushions the intestinal lining against the harmful effects of increased internal pressure that would otherwise result from apparatus fixation.
3Productivity
If treatment liquid is injected into the intestinal tract to facilitate bypass, then the fecal bypass function is enhanced, but peristalsis increases causing more abdominal pain
Solution Approach 1:
The liquid moving tube extracts excess liquid and pressure from the intestinal system. By removing the harmful byproduct (excess pressure and liquid) of the treatment process, it enables continued productivity enhancement without accumulating harmful effects that cause abdominal pain.
Solution Approach 2:
The liquid moving tube converts the harmful effect of increased peristalsis and pressure into a beneficial pressure relief mechanism. The same peristalsis that causes pain is channeled through the liquid moving tube to facilitate controlled liquid discharge, transforming the harmful motion into a useful pressure equalization function.
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 apparatus reduces abdominal pain by managing intestinal pressure and prevents damage to the intestinal lining, improving patient quality of life by minimizing complications and treatment time.
Implementation Method 1
a blocking part installed inside the main body part and expanding when air or liquid is injected so as to close a space inside the main body part
Implementation Method 2
a supporting portion formed to be spaced apart at an interval of 8 mm or more to 25 mm or less along an outer periphery of the main body part and fixing the main body part to be positioned at a rectum by expanding and being in close contact with an inner surface of the intestine when air or liquid is injected thereto
Implementation Method 3
a liquid moving tube installed inside the main body part to prevent closure even if the blocking part is expanded and allowing treatment liquid injected from an outside of an anus to be injected into intestines
Implementation Method 4
The apparatus reduces abdominal pain by managing intestinal pressure and prevents damage to the intestinal lining

AI summary
Disclosed is an auxiliary apparatus for fecal bypass for bypassing and discharging feces in the intestines. Since supporting portions are connected to a single air flow tube to simultaneously expand when air is injected, and the size of the supporting portions is limited, the auxiliary apparatus for fecal bypass of the present invention does not damage the inner wall and outer wall (mucous membrane and serous membrane) of the intestines. Also, the present invention comprises a liquid moving tube allowing a therapeutic liquid being refluxed quickly and automatically when the pressure inside the intestines increases, thereby preventing abdominal pain of a patient.
