ABSTRACT
Object To design a mobile class 1000 laminar flow clean field surgery unit to provide a clean space to facilitate the mobile medical rescue team to execute emergency operations in the field tent, private house and etc.Methods The principle of positive pressure isolation and finite element simulation were involved in the design of two-way air intake channel on the top, flexible isolation laminar flow clean module which could be constructed rapidly, three-stage composite clean air supply module and integrated surgery module with box instrumentation.Results The field surgery unit had all its performances meet the desired requirements, of which, the ventilation rate was 24 times per hour, the relative positive atmospheric pressure value was higher than 5 Pa in the surgical unit, and the cleanness reached level 6 at the operating and surrounding areas.Conclusion The field surgical unit can be deployed rapidly, and has the key indexes accord with the desired requirements for cleanness, ventilation rate and positive pressure difference, and thus can be used for the surgery support of the mobile medical rescue team during wartime operations and emergency medical rescue.
ABSTRACT
Objective To develop a set of field tent hospital system to further enhance campaign-level medical support service. Methods The system had its service orientation, functional requirements, component unit and modular elements determined with system analysis. The technical architecture was realized with tent combined with boxes, and the system modules were designed with the method of integrated box and instruments.Results The system had its design executed from the aspects of layout,composition of grid tent,medical functional units,support unit and packaging unit,which was applied in a series of military medical support operations in foreign countries and China as well as in the construction of national medical emergency rescue forces. Conclusion The system gains advantages in modularity, integration, completing, informatization and standardization,and thus greatly enhances the military medical support ability and national emergency medical rescue ability in China.[Chinese Medical Equipment Journal,2018,39(5):1-6,16]
ABSTRACT
The application of the reverse engineering and rapid prototyping technologies in the design of respiratory masks is introduced in this paper. Practice indicates that the technologies can reduce the cost and save the time in product developments.
