Surgical Orifice Connecting Device for Ileostomy Content Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with surgically created orifices, such as ileostomies, face challenges including fluid, electrolyte, and nutrient losses, dehydration, renal injury, and increased risk of anterior resection syndrome due to the need for stoma bags and prolonged use of ileostomies.
Innovation Solution
A connecting device that allows for the direct transfer of contents from one surgically created orifice to another without the need for a stoma bag, comprising elongate tubular members and an intermediate hollow body member with a cap to create a sealed pathway for passive content transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stoma bag is used to collect digestive contents from an ileostomy, then waste management is achieved, but fluid, electrolyte and nutrient losses occur leading to dehydration and renal injury
Solution Approach 1:
The patent introduces an intermediate hollow body member that acts as a mediator between the two surgically created orifices. This intermediate structure provides a controlled pathway for digestive contents to transfer from the first orifice to the second orifice, allowing the colon to remain in the gastrointestinal tract and continue its physiological functions of water and nutrient resorption, thereby reducing fluid and nutrient losses while still managing waste effectively.
2Reliability
If an ileostomy is maintained for extended periods (6-12 weeks) to allow healing, then surgical safety is improved, but patient quality of life deteriorates due to continuous stoma bag use and hospital resources
Solution Approach 1:
The patent extracts the stoma bag from the system by creating a direct connection between two surgically created orifices using tubular members. This eliminates the need for external waste collection devices, allowing patients to avoid continuous stoma bag use and associated hospital resources while maintaining surgical safety through controlled digestive content transfer.
3Productivity
If digestive contents bypass the colon during ileostomy, then waste evacuation is achieved, but the colon suffers from lack of nutrition leading to atrophy and anterior resection syndrome
Solution Approach 1:
The intermediate hollow body member serves as a mediator that allows digestive contents to reach the colon through the second tubular member inserted into the second orifice. This maintains the colon's position in the gastrointestinal tract and enables it to continue receiving nutritional material, preventing atrophy and anterior resection syndrome while still achieving effective waste evacuation.
4Ease of operation
If a stoma bag is used for waste collection, then waste management is achieved, but patient comfort and mobility are reduced due to the burden of wearing and managing the bag
Solution Approach 1:
The patent removes the stoma bag from the system by establishing a direct internal connection between two orifices using tubular members. This extraction eliminates the external waste collection device that causes patient discomfort and mobility restrictions, allowing patients to move freely without the burden of wearing and managing a stoma bag while still achieving effective waste management through controlled transfer of digestive contents.

AI summary
A device for connecting and transferring contents between a surgically created first orifice and a surgically created second orifice is provided. The device comprises a hollow body member and first and second tubular legs depending from the hollow body, and being adapted for insertion into the first and second surgically created orifices respectively. The device further comprises a cap for closing the hollow body and completing a sealed pathway between the tubular legs for passively conveying contents between the first and second surgically created orifices. Sealing features of the device are provided that in combination operate to keep the contents away from unwanted skin areas and/or provide an easy-to-use device.
