The automation level of medical anesthesia machines is generally low. Therefore, this study independently developed an economical and practical fully automatic intelligent medical anesthesia machine. Based on the automatic regulation of fresh gas delivery requirements, a multi-channel switching gas path structure was designed. Through the electronic control system, intelligent fresh gas delivery and multiple mechanical ventilation modes can be achieved. The system also has an alarm function and a complete safety mechanism, and uses a touch screen for control parameter setting and patient status monitoring. The test results based on the GASMAN platform show that the system can achieve safe and effective anesthesia induction, with a maximum relative deviation of 8.86%. This design can effectively reduce the workload of anesthesiologists and the consumption of anesthetic drugs, and lay a solid foundation for more intelligent functions of anesthesia machines in the future, with significant application value.
