Abstract

Предложено инъекционное устройство для неограниченно варьируемого дозирования и введения жидкого препарата из инъекционного картриджа с препаратом для многократного введения, содержащего задний поршень, который может перемещаться вперед за счет поршневого штока. Продольное перемещение поршневого штока управляется двумя муфтами, расположенными вдоль него, каждая из которых способна захватывать поршневой шток блокирующим средством с возможностью освобождения. Поршневой шток имеет клинообразное поперечное сечение, каждая из муфт содержит зажимной башмак с клинообразным пазом, поперечное сечение которого подогнано к поперечному сечению поршневого штока, и рычажные средства, с помощью которых поршневой ток и каждый зажимной башмак могут зажиматься вместе с возможностью освобождения, блокируя поршневой шток в пазе зажимного башмака.
