Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ostomy appliances lack personalization, leading to issues such as peristomal skin breakdown, hernias, and prolapse due to inefficiencies in fitting and design, which are not tailored to individual patient needs or anatomical variations.
Innovation Solution
The use of 3D scanning, computer-aided design modeling, and subtractive manufacturing techniques to create customized ostomy baseplates that fit each patient's unique anatomy, allowing for improved fit and reduced leakage through personalized ostomy systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If standard baseplates are used for all patients, then manufacturing cost and device simplicity are reduced, but fit accuracy and patient comfort deteriorate
Solution Approach 1:
The patent applies preliminary action by creating a 3D digital model of the patient's ostomy site before manufacturing the baseplate. This pre-planning allows for precise customization of the baseplate geometry to match the patient's unique anatomy, ensuring optimal fit accuracy while streamlining the subsequent manufacturing process through computer-aided design and subtractive manufacturing.
2Reliability
If standard baseplates are used, then ease of manufacture is improved, but reliability and prevention of complications worsen
Solution Approach 1:
The patent applies parameter changes by varying the geometric parameters of the baseplate based on the patient's specific anatomical measurements obtained from 3D scanning. This allows customization of baseplate shape, size, and opening dimensions to match individual patient needs, thereby improving reliability and preventing complications such as skin breakdown and hernias while maintaining manufacturability through automated subtractive manufacturing processes.
3Manufacturing precision
If scissors cutting is used to customize baseplates, then adaptability is improved, but manufacturing precision and fit quality worsen
Solution Approach 1:
The patent replaces the manual mechanical cutting process with automated subtractive manufacturing technology. This substitution enables precise cutting of the baseplate according to the patient's 3D anatomical model, achieving high manufacturing precision and customization capability simultaneously through computer-controlled manufacturing processes rather than manual scissors cutting.
4Adaptability or versatility
If binary convex/concave options are provided, then device complexity is reduced, but adaptability to different anatomies worsens
Solution Approach 1:
The patent applies local quality by customizing specific regions of the baseplate to match the patient's local anatomical characteristics. Rather than offering only binary convex or concave options, the 3D scanning and customization process allows different parts of the baseplate to have different geometries tailored to the patient's specific ostomy site morphology, providing superior anatomical adaptability while using automated manufacturing to control complexity.

AI summary
A personalized ostomy appliance, including a baseplate, leveraging three-dimensional (“3D”) scanning, computer-aided design modeling, and 3D printing technology, to empower patients to improve quality of life and decrease ostomy complications. In embodiments, the process uses 3D scanning technology to create a raw peristomal mesh. In embodiments, this mesh is filtered using a smoothing and splicing algorithm with patient-specified preference variables. In embodiments, this personalized filtered mesh is then used in a subtractive manufacturing process, including applying a laser cutter or blade press, to alter an ostomy baseplate. The personalized filtered mesh can also used to 3D print a personalized ostomy template that improves fit of the baseplate using a retraction method. This process can be applied to wound care with negative pressure vacuum therapy and fistula management systems wherein a vacuum or pouch baseplate is generated for improved fit and healing.
