Development of maintenance learning machine of ventilator for teaching / 中国医学装备

ABSTRACT

Objective: To design a new type of maintenance learning machine of ventilator for teaching and experiment combined with electronic technology course of higher vocational education. Methods: ACM804 ventilator was chosen as prototype machine and the electronic technology course of higher vocational education was chosen as theory basis. The designs of internal circuit and gas circuit of prototype machine were improved, besides, some test points and failure points were designed for teaching in classroom. Results: This machine not only could realize all functions of prototype machine, but also could carry forward test teaching and contribute students to maintain common failure in accordance with course content. Conclusion: Through the design of teaching experiment and using of learning machine, the new machine has achieved better teaching effect for students to grasp machine theory and operate actual circuit.
