Abstract

resumo patente de invenção: "mecanismo de retrocesso para caneta wind-up". a presente invenção refere-se a um dispositivo de injeção conduzido por uma mola de torção que tem um mecanismo de retrocesso para retroceder um tamanho de dose selecionado. a mola de torção (2) é tensionada ao definir uma dose girando um botão de ajuste de dose (30) localizado proximalmente em relação à carcaça em uma primeira direção e liberado do tensionamento ao girar o mesmo botão de ajuste de dose (30) em uma segunda direção contrária à primeira direção. com o objetivo de segurar a mola de torção (2) na sua posição tensionada, um mecanismo de catraca unidirecional é fornecido. esse mecanismo de catraca unidirecional é composto por um elemento de fixação (1) acoplado à carcaça e tendo uma parte de dentes (6) e um elemento de catraca (20) tendo pelo menos um braço de catraca (22) que envolve o elemento de fixação (1) e cujo elemento de catraca (20) é operacionalmente acoplado ao botão de ajuste de dose (30). o botão de ajuste de dose (30) envolve diretamente o pelo menos um braço de catraca (22) quando o botão de ajuste de dose (30) é girado no segundo sentido, o que libera o pelo menos um braço de catraca (22) da parte de dentes (6) do elemento de fixação (1) e permite que o elemento de catraca (20) possa girar em relação ao elemento de fixação (1) na segunda direção sob a influência da mola de torção (2).
