Abstract

В данном документе описаны устройства для доставки некоторого объема лекарственного препарата, препарата плацебо или другого препарата, включающего жидкость. Устройства могут содержать цилиндр, имеющий продольную ось, область проксимального конца и область дистального конца. Область проксимального конца может содержать отверстие, и цилиндр может быть выполнен с возможностью приема в нем лекарственного препарата. Шток поршня может быть расположен, по меньшей мере частично, внутри цилиндра и выступает из отверстия. Шток поршня может содержать зубчатую рейку, имеющую множество зубьев. Устройство может дополнительно содержать шестерню, имеющую множество зубьев, выполненных с возможностью зацепления с множеством зубьев зубчатой рейки, и вращение шестерни относительно зубчатой рейки может перемещать по меньшей мере часть штока поршня вдоль продольной оси цилиндра.This document describes devices for delivering a volume of a drug, a placebo drug, or other drug that includes a liquid. The devices may comprise a cylinder having a longitudinal axis, a proximal end region, and a distal end region. The proximal end region may contain an opening and the cylinder may be configured to receive a medication therein. The piston rod may be located at least partially within the cylinder and protrude from the bore. The piston rod may comprise a rack having a plurality of teeth. The device may further comprise a gear having a plurality of teeth adapted to mesh with a plurality of teeth of the rack, and rotation of the pinion relative to the rack may move at least a portion of the piston rod along the longitudinal axis of the cylinder.
