Abstract
válvula rolha para um dispositivo de injeção médica e dispositivo de injeção médica para injetar pelo menos uma composição. a invenção diz respeito a uma válvula rolha (1) configurada para ser posicionada dentro de um cilindro (101) de um dispositivo de injeção (100) para injetar pelo menos uma composição através de uma extremidade distal (104) do cilindro, a dita válvula rolha (1) compreendendo: uma membrana (2) compreendendo uma face proximal (6) e uma face distal (7), a membrana sendo configurada para separar uma primeira câmara (distal) (108) do cilindro de uma segunda câmara (proximal) (109) do cilindro, uma parede lateral (3) se estendendo distalmente, ou tanto distalmente quanto proximalmente, da membrana (2) para definir pelo menos uma cavidade distal (4), a parede lateral (3) compreendendo uma superfície de vedação circunferencial (8) configurada para encaixar de modo vedado com a superfície interna (102) do cilindro, caracterizada em que a face proximal (6) da membrana (2) apresenta uma forma côncava e a membrana (2) compreende uma fenda (10, 20) se estendendo através de pelo menos uma parte da espessura da membrana (2) entre a face proximal (6) e a face distal (7), a fenda (10, 20) sendo configurada para criar seletivamente um caminho de fluido (30) através da membrana (2) da face proximal (6) para a face distal (7) dependendo da pressão exercida por uma composição sobre a face proximal (6) da membrana (2) para transferir fluido somente da segunda câmara (109) para a primeira câmara (108).
