Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ulcer models for endoscopic procedures cannot simulate hemorrhage arrest, limiting the practice of hemorrhage arrest techniques in gastrointestinal tract models.
Innovation Solution
An ulcer model with a tubular simulated blood vessel path, a ring-shaped raised surface, and a recessed simulated ulcer surface, made from materials like aqueous polyvinyl alcohol-based or hydrocarbon-based resin, allowing for hemorrhage arrest simulation through mechanical or thermocoagulation methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple ulcer model is used for endoscopic observation, then the model structure is simple and easy to manufacture, but it cannot simulate hemorrhage arrest procedures
Solution Approach 1:
The simulated blood vessel path is nested within the model main body, with the vessel path embedded in the ulcer model structure. This allows the complex function of hemorrhage simulation to be integrated within the simple ulcer model framework, resolving the contradiction between structural simplicity and functional versatility.
Solution Approach 2:
A simulated blood vessel path acts as an intermediary element between the ulcer surface and the hemorrhage arrest procedure. This intermediary structure enables the simulation of bleeding and hemostasis without requiring complex additional components, maintaining manufacturing simplicity while achieving procedural versatility.
2Ease of manufacture
If existing ulcer models are used, then manufacturing is straightforward, but they lack the simulated blood vessel path needed for hemorrhage arrest practice
Solution Approach 1:
The simulated blood vessel path is localized within specific regions of the model main body, particularly around the ulcer surface area where hemorrhage arrest is needed. This localized approach allows straightforward manufacturing of the overall model while incorporating the necessary vascular simulation for reliable hemorrhage practice.
3Adaptability or versatility
If a complex model with hemorrhage simulation is created, then hemorrhage arrest practice is enabled, but the model structure becomes complicated and harder to manufacture
Solution Approach 1:
The model main body serves multiple functions: it provides the ulcer surface for observation, contains the simulated blood vessel path for hemorrhage simulation, and supports various hemorrhage arrest procedures. This multi-functionality reduces the need for separate complex components, enabling hemorrhage practice without excessive structural complexity.

AI summary
Disclosed is an ulcer model used to practice a procedure including hemorrhage arrest, the ulcer model including a model main body which includes upper and lower surfaces facing each other and a tubular simulated blood vessel path provided between the upper surface and the lower surface and having an inlet opening and an outlet opening. The upper surface includes a ring-shaped raised surface that rises in a thickness direction of the model main body and a simulated ulcer surface that is a recessed bottom surface surrounded by the raised surface. The simulated blood vessel path extends from a part other than the upper surface of the surfaces of the model main body to the simulated ulcer surface or an area in the vicinity of the inside thereof.
