Abstract

"MECANISMO DE ACIONAMENTO PARA UM DISPOSITIVO DE INJEçãO". Dispositivos de injeção são conhecidos para a auto-administração de medicamentos por pacientes, onde o medicamento está tipicamente contido dentro de um cartucho localizado no interior do dispositivo de injeção. Constitui um problema o fato de que os dispositivos de injeção devem ser bastante pequenos para caberem em bolso de paletó ou em uma bolsa de mão sem dificuldade. Também, o dispositivo de injeção tem de ser de um tamanho que habilite um êmbolo ou similar usado para acionar o batoque de um cartucho no interior do cartucho a ser deslocado tanto para uma posição de administração máxima no interior do cartucho como para ser completamente extraído do cartucho para permitir a substituição do cartucho. Um mecanismo de acionamento para um dispositivo de injeção é exposto no qual um segundo êmbolo (42) é sucessivamente movido em relação a uma primeira extremidade de um cartucho de medicamento (8) contendo um medicamento seletivamente para acionar um batoque (10) no interior do cartucho de deslocamento (8), o mecanismo de acionamento compreendendo um dispositivo (36) definindo uma passagem (38), um primeiro êmbolo (40) e o segundo êmbolo (42), no qual a passagem (38) tem uma primeira extremidade e uma segunda extremidade, o primeiro êmbolo (40) fechando a primeira extremidade da passagem (38) e uma primeira extremidade do segundo êmbolo (42) fechando a segunda extremidade da passagem (38) para definir uma câmara na passagem (38), um meio não compressível sendo contido no interior da câmara de tal modo que um primeiro deslocamento recíproco em uma primeira direção na primeira extremidade da passagem (38) resulta em um segundo deslocamento recíproco numa direção oposta à primeira direção na segunda extremidade da passagem (38).
