Stoma Device Base Plate Opening Formation Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with stomas face challenges in accurately cutting base plates for stoma devices due to shape variations and clumsiness, leading to improper fit and potential skin injuries or inflammation.
Innovation Solution
A method involving a template sheet with printed contour lines, scanned and processed to create a label with filled-in image data, which is then used to accurately cut an opening in the base plate matching the stoma shape, ensuring precise fit and minimizing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the patient cuts the base plate manually to match the stoma shape, then the patient can customize the opening shape, but the cutting accuracy deteriorates due to patient clumsiness or poor eyesight
Solution Approach 1:
The patent uses a template sheet with a hole matching the stoma shape, which is scanned to create digital image data. This digital copy is then printed on a label and transferred to the base plate, allowing the patient to cut along precise printed contours rather than freehand cutting, thus maintaining customization while improving accuracy
Solution Approach 2:
The patent introduces an intermediary process involving scanning the template sheet, processing the image data to create filled-in contour patterns, and printing these patterns on transferable labels. This intermediary digital processing step acts as a mediator between the original stoma shape and the final base plate opening, ensuring high precision
2Ease of manufacture
If the patient draws the stoma shape on cardboard and faxes it to a cutting service, then the patient can obtain a custom-shaped base plate, but the shape accuracy deteriorates due to fax distortion or line thickness
Solution Approach 1:
The patent replaces the mechanical fax transmission and manual drawing process with a digital imaging system. The template sheet with the stoma-shaped hole is scanned to create precise digital image data, which is then processed to generate filled-in contour patterns. This substitution of mechanical processes with digital imaging and processing eliminates fax distortion and line thickness issues
Solution Approach 2:
Instead of copying the stoma shape through fax transmission of a drawn cardboard, the patent creates a digital copy by scanning the template sheet. This digital copy is then processed to create filled-in image data with precise contours, which is printed on transferable labels for accurate base plate cutting
3Ease of operation
If the patient draws with a thick line on cardboard, then the drawing is easily visible, but the opening size deteriorates due to uncertainty whether to cut inside or outside the line
Solution Approach 1:
The patent creates a precise digital copy of the stoma shape through scanning the template sheet. The image processing fills in the hole area to create a solid pattern with a single, unambiguous contour line. This eliminates the thick-line problem by providing a clear, precise cutting path that is neither too thick nor ambiguous

AI summary
Providing a method for forming an opening of a shape precisely matching the stoma of a patient in a base plate of a stoma device. A method of forming an opening in a base plate of a stoma device according to the present invention comprises a step of printing on a label a filled-in-part of the same shape as a hole of a shape formed on a template sheet and matching the stoma of a patient, a step of sticking the label on which the filled-in-part has been printed on to a base plate, and a step of cutting the base plate along the contours of the filled-in-part of the label stuck to the base plate.
