The MCD0213 is a purely pneumatic dental sedation system that precisely regulates nitrous oxide (N2O, 0~70%) and oxygen (O2, 30%~100%) mixtures for rapid sedation and analgesia. It significantly reduces pain scores (VAS from 7.2 to 2.1) and is safe for hypertensive and cardiac patients with stable vital signs. Patients remain conscious with spontaneous breathing throughout the procedure, suitable for pediatric dentistry, implant surgery, and other scenarios. No specialized anesthesia certification is required, and its power-free design ensures safety in diverse environments.
