Solution Overview
Problem
Conventional bronchoscopy simulators fail to reproduce the bleeding phenomenon occurring during actual bronchoscopy procedures, limiting the training of inexperienced doctors in realistic conditions.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bronchoscopy simulators are used, then the structure is simple and easy to operate, but the bleeding phenomenon cannot be reproduced
Solution Approach 1:
The simulator is divided into independent functional modules: a blood reservoir unit, a blood delivery system with conduits, a control unit with valves, and a main body part. This segmentation allows each component to be optimized independently while maintaining overall system functionality, enabling realistic bleeding simulation without excessive complexity.
Solution Approach 2:
Artificial blood is introduced as an intermediary substance to simulate real bleeding conditions. The artificial blood flows through controlled conduits and exits at specific locations in the main body part, creating a realistic training environment without using actual biological blood, thus maintaining safety while improving training realism.
2Adaptability or versatility
If a bleeding simulation system is added, then realistic training scenarios are achieved, but the device complexity increases
Solution Approach 1:
The control unit is designed with multiple valves that can be independently controlled to create various bleeding scenarios. The same basic infrastructure (blood reservoir, conduits, control unit) supports multiple training situations by simply adjusting valve configurations, enabling one system to serve multiple training purposes without requiring separate specialized equipment for each scenario.
Solution Approach 2:
The system incorporates dynamically controllable elements through the valve mechanism, allowing the bleeding rate, pressure, and flow characteristics to be adjusted in real-time. This dynamic control enables the simulator to adapt to different training requirements, from slow oozing to rapid bleeding, without changing the physical structure of the device.

AI summary
A bronchoscopy simulator includes: a main body part which is formed to be similar to the bronchial tree of the human body; and a bleeding producing part which is provided on the main body part to create a situation where bleeding occurs bronchial tree inside the main body part, thereby enabling practice of a response process for bleeding situations occurring during bronchoscopy. A control method for the bronchoscope simulator, includes: a bleeding occurrence step in which bleeding occurs inside a main body part by a bleeding simulation part; and a bleeding stop step, after hemostasis responding to the bleeding is performed, in which the bleeding is stopped by the bleeding simulation part.
