The operation steps of the advanced transparent gastric lavage model are mainly used for nursing and clinical skills training, which can help trainees master the entire process of gastric lavage in an intuitive environment.

Before operation, it is necessary to first check whether the model is intact, ensure that the gastric cavity and the pipeline are unobstructed, and prepare relevant items such as gastric lavage solution, gastric tube, syringe and liquid collection container.

The first step is that trainees should strictly follow aseptic operation, wear gloves and explain the purpose of the operation, and simulate to obtain the patient's cooperation.

The second step is to select the appropriate model of gastric tube, measure the length of the tube insertion, and after lubrication, slowly insert it into the esophagus of the model into the stomach through the mouth or nose. Pay attention to observing the direction of the tube in the transparent structure to ensure its accurate position.

The third step is to first inject a small amount of warm water to verify whether the gastric tube is in the gastric cavity. Then, connect a syringe or funnel to inject the gastric lavage solution in several portions, and observe the inflow and outflow of the liquid at the same time.

The fourth step is to repeatedly perform the injection and drainage operations until the liquid becomes clear or the training objective is achieved.

The fifth step is to slowly pull out the gastric tube after the operation is completed, rinse, clean and disinfect the interior of the model, and store it properly. Through standardized step-by-step practice, trainees can not only master the key points of gastric lavage operations, but also intuitively understand the flow of liquids and common mistakes, thereby enhancing their clinical skills and safety awareness.
