Abstract

Предложена система поршневого штока для шприцев. Система содержит, по меньшей мере, поршень или связанный с ним шток для приложения усилия к поршню. Шток содержит конец с резьбовым элементом, содержащим резьбу определенной геометрии, которая позволяет легко вставлять шток в поршень при обеспечении сопротивления извлекающим силам, которые могут быть приложены при вытягивании или извлечении штока или поршня из цилиндра.
