Abstract

a presente invenção refere-se a uma válvula de retenção (7) para câmaras de gotejamento (1) de aparelhos médicos de infusão ou de transfusão, que têm um assento de válvula anular (15) com o qual um obturador flutuante (11), que pode ser deslocado de modo axial entre uma posição para fechamento e uma posição para abertura do assento da válvula (15), coopera. a válvula de retenção (7) compreende uma bucha de contenção (8) que tem uma parede lateral elasticamente deformável (9) dentro da qual o obturador flutuante (11) flutua de forma guiada e a parede lateral (9) da bucha de contenção (8) e o obturador flutuante (11) têm respectivas superfícies voltadas uma para a outra (14, 18) e configuradas de tal modo que uma deformação radial da bucha de contenção (8) aplica um empuxo axial ao obturador flutuante (11) na direção de afastá-lo do assento da válvula anular (15).
