Precautions for the advanced sputum aspiration practice model

When using the advanced sputum aspiration practice model for teaching and operation training, the operation norms should be strictly followed to ensure the safety and effectiveness of the training. First of all, before use, carefully check whether the airway system, respiratory duct and suction port of the model are unobstructed, and confirm that there is no blockage or leakage. Secondly, before operation, one should be familiar with the structure and function of the model, understand the setting methods of the simulated airway, throat and secretion system, and avoid model damage caused by improper operation.

During the sputum aspiration training process, the insertion depth and Angle of the sputum aspiration tube should be standardized to avoid excessive insertion which may cause damage to the internal structure of the model. At the same time, the aseptic principle in real operation should be simulated to keep the sputum aspiration tube and its accessories clean and hygienic. The suction pressure and time should be controlled within a reasonable range to prevent the model's service life from being affected due to excessive negative pressure or excessively long operation time.

After the operation is completed, the residual liquid or secretions inside the model should be cleaned up in time, and all components should be washed with clean water or neutral detergent, and kept dry for storage. In addition, it is necessary to regularly check whether all connection parts of the model and the electronic control system (if any) are normal to prevent aging or damage. Proper maintenance and standardized operation can not only extend the service life of the model, but also enhance the realism and teaching quality of sputum aspiration skills training
