Abstract

caneta de injeção de pré-carga ajustável de múltiplas doses. caneta de injeção de pré-carga ajustável de múltiplas doses, compreendendo um corpo de caneta, uma haste de pressão de injeção (13), uma luva de haste de pressão de injeção (7), um cubo de embreagem (6), um membro limitador de extremidade (8) e um cubo de dose (14). a haste de pressão de injeção (13) está em conexão roscada com o corpo da caneta; a luva da haste de pressão (7) e a haste de pressão de injeção (13) estão em encaixe deslizante uma com a outra na direção da injeção e podem transmitir torque na direção de aparafusamento da haste de pressão de injeção (13); a luva da haste de pressão (7) e o corpo da caneta são conectados por meio de um primeiro conjunto de mecanismo de lingueta de catraca; o cubo da embreagem (6) e a luva da haste (7) estão em encaixe deslizante um com o outro na direção da injeção; o cubo de dose (14) é conectado rotativamente ao corpo da caneta por meio de roscas; a rotação entre o cubo da embreagem (6) e o cubo de dose (14) é limitado por uma estrutura de fixação capaz de ser desengatada do sentido de injeção; o membro limitador de extremidade (8) e o cubo de dose (14) são suportados por um pé de suporte (83) capaz de se deformar elasticamente na direção da injeção; o cubo de dose (14) pode ser girado para empurrar a estrutura de fixação para ser desengatado antes que o pé de suporte (83) se deforme elasticamente, resolvendo assim efetivamente o problema de que uma caneta de injeção existente é inconveniente de operar e o efeito de ajuste de dose é ruim.
