From the position of the functional approach - there are diagnostic, therapeutic (invasive, non invasive), rehabilitation, prevention, and technologies for care and maintenance functions. Regarding the use of different components, there are technologies which include drugs or blood components, also foodstuffs for special nutritional uses or medical devices. An example of medical devices may be laboratory gear used for in vitro studies. The paper presents evaluation results of technologies, which employ medical devices. Finally, there are institutional medical technologies. In this article, the authors present studies about therapeutic, prophylactic and organizational technologies.
