Abstract

Предложено медицинское устройство для доставки для продвижения поршня в емкости для лекарственного препарата с целью выталкивания лекарственного препарата. Опорная конструкция поддерживает емкость и узел привода, который продвигает поршень. Узел привода содержит приводную ленту, которая может быть втянута и выдвинута. Втянутая лента образует плоскую спираль, и выдвинутая лента образует цилиндрическую спираль. Приводная лента выполнена с возможностью перемещения с дискретным приращением между втянутой плоской спиральной конфигурацией и выдвинутой цилиндрической спиральной конфигурацией. Механический привод вращает приводную ленту для выборочного выдвижения и втягивания ленты. Упорный элемент, имеющий цилиндрическую спиральную наклонную секцию, взаимодействует с проксимальным краем приводной ленты на участке, на котором она перемещается между плоской спиралью и цилиндрической спиралью. Опорный элемент, расположенный в дистальном конце приводной ленты, прикладывает осевую силу к поршню, когда лента выдвинута.
