Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stoma systems often lead to spillage, odor escape, and excessive inflammation due to poor fit and compatibility between the stoma and ostomy pouch.
Innovation Solution
A customizable stoma insert is manufactured using 3D scanning and additive manufacturing to create a custom mold mirroring the stoma and surrounding skin, ensuring a snug fit and incorporating antimicrobial, anti-inflammatory, and deodorant compounds to reduce irritation and odor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stoma systems are used, then the basic function of drainage is achieved, but spillage and odor escape occur due to poor fit
Solution Approach 1:
The stoma insert is customized to match the specific local geometry of each patient's stoma and surrounding skin area. The 3D scanning and additive manufacturing process creates a unique insert with varying thickness and contour characteristics tailored to the individual patient's anatomy, ensuring optimal fit and preventing spillage and odor escape.
Solution Approach 2:
The invention changes the geometric parameters of the stoma insert by creating customized versions for each patient based on their specific stoma morphology. The insert thickness, diameter, and surface contour are all optimized parameters that are adjusted to match the patient's unique anatomy, improving seal quality and preventing harmful effects.
2Reliability
If conventional stoma systems are used, then drainage function is provided, but excessive inflammation occurs due to poor compatibility
Solution Approach 1:
The insert incorporates different material properties in different regions to address local skin conditions. The varying thickness and material composition are tailored to specific areas around the stoma, providing enhanced comfort and reducing inflammation in sensitive regions while maintaining effective drainage function.
3Manufacturing precision
If custom molds are created using additive manufacturing, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The invention utilizes additive manufacturing technology to precisely control and vary the geometric parameters of the stoma insert. By digitally modeling the insert based on 3D scans and then manufacturing it layer-by-layer, the process achieves high contour accuracy while managing complexity through automated digital workflows rather than manual fabrication.

AI summary
The disclosure relates to a method of manufacturing a custom stoma insert for a patient having a stoma, as well as to a stoma made using the method of the disclosure. The method comprises the steps of scanning the stoma and surrounding skin area to generate a three-dimensional scan of the area for which the stoma insert is to be manufactured; manipulating scan data obtained from the three-dimensional scan to render a three-dimensional model of the stoma and surrounding skin contours, such that the scan data is suitable for use in an additive manufacturing environment; creating a custom mold for the stoma insert using additive manufacturing such that the mold provides a complementary surface closely mirroring the contours of the stoma and surrounding skin area; and producing the stoma insert by casting a physiologically acceptable moldable material into the custom mold.
