A teaching-grade intelligent suctioning model

Abstract

This utility model discloses an intelligent suctioning model for teaching purposes, relating to the field of medical teaching equipment technology. It includes a human body model with a positioning tube at the trachea position in the neck. An insertion tube is located inside the positioning tube, with one end extending into the human body model. A laser ranging sensor is located inside the human body model, on the side furthest from the positioning tube and corresponding to its position. An LED tri-color indicator light is located inside the human body model on the side closest to the positioning tube, and an alarm is also installed inside the model. The LED tri-color indicator light provides real-time feedback on the insertion tube length: orange for too short, green for a suitable length, and red for too long. This allows medical personnel to intuitively understand whether the insertion tube length is appropriate, adjust the operation promptly, and help standardize the insertion procedure, avoiding poor suctioning effects or potential harm to the patient due to an excessively short or long insertion tube.
