Case study: medical motors for anaesthesia machines
The rapid advancement of medical motor technology in recent years means that certain medical procedures like surgery under general anaesthetic and undergoing ventilation procedures are significantly safer and more comfortable now than in the past. Precisely engineered drive solutions play a vital role in enhancing the efficiency of these complex systems.
The Zeus Infinity Empowered (IE) anaesthesia machine by Dräger seamlessly encompasses a wide range of functions, spanning advanced ventilation therapy, comprehensive monitoring, integration of infusion technology and automation of sub-functions, all within a single, unified system.
Interchangeable and sterilisable turbine unit
Equipped with a turbine ventilator, this device can function as a closed anaesthesia system with complete rebreathing capabilities. Precise control over the anaesthesia gas within the closed system minimises gas consumption and anaesthetic exposure.
The turbine-based ventilation enables patients to maintain spontaneous breathing throughout the entire anaesthesia process. The turbine unit, also known as a blower unit, can be effortlessly replaced when needed and is autoclavable, ensuring sterilisation through intensive treatment with 134°C steam.
Nonetheless, stringent requirements are imposed on the system’s components as they must tolerate exposure to hot steam. All components within the turbine unit must be constructed exclusively from biocompatible materials, as they come into direct contact with the patient's breathing air. Additionally, compact dimensions and a high-power density are essential to seamlessly integrate the unit into the anaesthesia machine and facilitate easy replacement and cleaning procedures.
