Análise de anterioridade referente ao estado da técnica acerca de dispositivos de fixação de tubo orotraqueal

Abstract

Previous research can contribute to identifying the main orotracheal tube fixation devices developed, verifying the main problems encountered and favoring the development of new, more effective devices. Descriptive, documentary study, with a quantitative approach carried out in three patent databases. A total of 29,036 registered and only 64 registered patents compatible with the endotracheal tube fixator were identified, distributed among the platforms, which revealed that there is a diversity of fixation methods used, mainly focused on the use of adhesive tapes. Need for investment in research and innovation in the area of orotracheal tube fixation as well as the development of safer methods.
