The transparent gastric lavage mechanism model with warning is a teaching device for gastric lavage operation specially designed for clinical nursing and emergency training. Its notable features are the transparent structure and warning feedback system. The transparent gastric body and esophageal passage enable trainees to clearly observe the path, direction and depth of the catheter insertion, which is helpful for understanding the key steps and potential risk points in the gastric lavage process.

The model is equipped with a built-in "position warning mechanism". When the catheter is placed in the wrong position, inserted too deeply or operated improperly, it will emit sound or light alerts to help trainees make timely adjustments and reduce the occurrence of dangers such as accidentally entering the airway or perforation during actual operations.

This model is widely used in nursing colleges, emergency departments of hospitals, gastroenterology departments and skills training centers to teach the complete process of gastric lavage tube insertion, fluid perfusion, negative pressure aspiration and observation of effluent. Through repeated practice, trainees can master standardized operations proficiently in a risk-free environment and enhance their ability to respond to clinical situations such as acute poisoning and gastric contents clearance.

Overall, this model has advantages such as being intuitive, visual, safe, and providing timely feedback, making it an important tool for conducting gastric lavage skills training.
