Abstract

Инъекционное устройство для использования со шприцом 30, содержащим канал (32), проходящий от торцевой поверхности (34), иглу (36), сообщающуюся с каналом сквозь торцевую поверхность, и дозирующий поршень (38), установленный в упомянутом канале с возможностью перемещения в направлении упомянутой торцевой поверхности для вытеснения содержимого шприца сквозь иглу, при этом инъекционное устройство содержит корпус (60) с отверстием (64) на одном торце, через которое может выдвигаться игла, упругий элемент для подпружинивания шприца и иглы в направлении внутрь корпуса, приводной элемент (66), установленный с возможностью перемещения в направлении упомянутого одного торца для выдвижения иглы шприца из отверстия с преодолением усилия упругого элемента и перемещения дозирующего поршня шприца в направлении торцевой поверхности, расцепляющий механизм (72), установленный с возможностью деблокирования шприца так, что игла перемещается внутрь корпуса, приводную муфту (40), длиной от упомянутого приводного элемента до дозирующего поршня шприца с возможностью передачи перемещения упомянутого приводного элемента на дозирующий поршень, в котором приводная муфта постепенно сокращается в длину так, что после того как приводной элемент переместит дозирующий поршень до торцевой поверхности, приводной элемент продолжает перемещать упомянутый дозирующий поршень в направлении упомянутой торцевой поверхности и продолжает перемещаться постепенно в упомянутое заданное положение, в котором упомянутый расцепляющий механизм деблокирует шприц.Международная заявка была опубликована вместе с отчетом о международном поиске.
