Abstract

"CONJUNTO DE VáLVULA PARA USO COM UMA SERINGA E A QUAL PREVINE O CONTRAFLUXO". O conjunto de uma válvula de uso único pode ser fixado na extremidade de uma seringa para permitir que o fluído flua da seringa para dentro de uma cavidade corporal mas prevenindo contrafluxo. O conjunto de válvula é aberta pela inserção de ponta luer de seringa no conjunto de entrada. A válvula possui um membro elástico interno que forma um compartimento interno de volume variável. Este compartimento expande sobre a inserção da ponta luer na entrada e encolhe quando a ponta luer é removida a partir da unidade. A ação de encolhimento cria uma pressão positiva na unidade de válvula para prevenir que o contrafluxo.
