Description

TECHNICAL FIELD

[0001] The utility model relates to the field of simulation teaching model, especially a sputum suction device for simulating sputum suction operation of simulation model. BACKGROUND

[0002] The enteral nutrition teaching model is a simulation tool for teaching and training purposes, aiming to help medical students, nursing staff or other relevant professionals learn the principles, operation techniques and clinical applications of enteral nutrition support. These models usually simulate the structure and function of the human intestinal tract, and can be used to demonstrate the process of inserting an enteral nutrition catheter, the correct method of using enteral nutrition products, monitoring and managing enteral nutrition complications, etc. However, the current teaching models and methods on the market still have many defects and need to be improved.

[0003] In nursing work, patients with sleepiness, coma and other conditions, and a large amount of sputum, cannot cough out the sputum themselves and accumulate in the trachea, which may cause respiratory difficulty, hypoxia, etc. In critical situations, it may lead to acute respiratory failure, asphyxia, and increase the incidence of pulmonary infection. The trachea can be cut open and the sputum suctioned to ensure the patency of the airway. During the sputum suctioning process, the negative pressure needs to be adjusted to 0.02-0.027 MPa according to the requirements of medical care, the negative pressure at the end of the sputum suction tube is blocked, and then the sputum suction tube is inserted further, with a depth of 14-16 cm, and the sputum suction tube is rotated left and right while being pulled upward for sputum suction operation. The existing simulation models have low simulation degree, and only the operation method outside the model can be used to artificially judge whether the operation method is standard. Because the insertion depth of the sputum suction tube in the model is unknown, it is impossible to estimate whether it is inserted into the intracranial, trachea or stomach, and the simulation degree of the teaching is not high, which is not conducive to the students' later practical operation. Moreover, it is also impossible to know whether the students have performed the sputum suction operation by rotating the sputum suction tube in the simulation model, and the evaluation and scoring cannot be quantified, which is not conducive to the teacher's scoring.
