An infusion model for clinical nursing teaching

technical field

The utility model relates to the technical field of medical models, in particular to an infusion model for clinical nursing teaching.

Background technique

The teaching model is a medical-related model that simulates a certain part of the human body for teaching. Most of the models are made of PVC material. The teaching model vividly shows the functions and characteristics of certain parts of the human body. At present, intravenous infusion It is the most commonly used clinical treatment method, and it is also the core technical ability that nurses must have. Therefore, medical schools usually use model teaching or real practice to teach this skill. The traditional infusion model is simple in structure and lacks in simulation, and cannot correct the wrong needle insertion technique of the students during use. For this reason, we propose an infusion model for clinical nursing teaching.

The Chinese patent application No. 201721384812.6 discloses an intravenous infusion model for clinical nursing teaching.
