摘要

A description is given of a medical respirator based on the technology of closed cycle life support systems. Four prototype units were designed, fabricated and delivered to the National Naval Medical Center, Bethesda, Maryland for laboratory and clinical evaluation. System performance requirements were selected to meet the needs of military use and the overall design was bounded by the requirement for portability and extended autonomous operation. An eleven month program starting in June, 1969, translated these requirements to prototype hardware which underwent comprehensive performance testing at the component, sub-system and system levels prior to delivery. This testing amply demonstrated the capability of the prototype systems to satisfy the performance requirements. This report summarizes the design and development efforts addressed to defining the prototype configuration and presents a complete physical description of the system. In addition, system calibration and test procedures, along with typical results, are presented. (Author)
