The S12A Anesthesia Machine

The S12A Anesthesia Machine is designed to deliver safe, precise, and reliable anesthesia care for both adult and pediatric patients. Built with a strong emphasis on stability and ease of use, it integrates advanced monitoring, intelligent safety systems, and flexible ventilation modes to support a wide range of clinical environments.

At the center of the S12A is a 12.1‑inch high‑definition color LCD screen, which provides clear, real‑time visualization of ventilation parameters, alarm messages, waveforms, and ring diagrams. The interface supports both touchscreen and physical button controls, allowing clinicians to operate the machine comfortably in any situation. A day/night display mode enhances visibility and reduces fatigue during long procedures.

To ensure continuous operation, the S12A includes an automatic power‑outage support function that switches to an internal backup power supply if mains power is interrupted. This feature helps maintain patient safety during unexpected electrical failures.

The machine supports multiple ventilation strategies, including capacity control and pressure‑limit modes, enabling clinicians to tailor anesthesia delivery to individual patient needs. The S12/S15 series metal breathing circuits include heating and bypass functions, helping maintain stable gas temperature and flow.

Additional precision is provided through temperature, flow, and pressure compensation, along with an anesthetic evaporator featuring automatic altitude compensation and zero‑position self‑locking for enhanced accuracy. A four‑ or five‑tube mechanical flow meter with an oxygen–nitrous oxide linkage system ensures oxygen concentration remains at 25% or higher, preventing hypoxic mixtures. Safety is further reinforced with an O₂ driving pressure alarm and N₂O cut‑off protection.
