Abstract

Приведено описание средства регулирования втягивания иглы в безопасном шприце с автоматически втягиваемой иглой для сведения к минимуму забрызгивания или разбрызгивания. Конец полого штока (11) закрыт уплотнительным элементом (14), который при втягивании смещается с обеспечением вхождения узла иглы и уплотнения в полый шток. Приведено описание трех способов регулирования автоматического втягивания иглы. Во-первых, предлагается выполнение сужения внутри полого штока, которое создает переменное сопротивление для перемещения уплотнительного элемента. Во-вторых, предлагается выполнение выпускного отверстия (15) в верхнем конце полого штока, с помощью которого обеспечивается выпуск воздуха. В-третьих, предлагается создание по меньшей мере одного паза (16) по периферии уплотнения штока с обеспечением выпуска воздуха для уменьшения давления в штоке и, соответственно, возможности забрызгивания.
