Abstract

Безыгольный инъектор (10) предназначен для введения дозы раствора внутримышечно, внутрикожно или под кожу животного или человека. Инъектор содержит внутренний корпус (12) с противоположными концами. На одном конце внутреннего корпуса расположен шприц (18) с отверстием (40) для выхода медикаментозного раствора. Шприц содержит подвижный поршень (38). Внутренний корпус содержит подпружиненный ударник (44). Ударник взаимодействует с поршнем, который выталкивает раствор через выходное отверстие. Между вторым концом внутреннего корпуса и ударником расположена сжатая инъекционная пружина (36), которая приводит в действие ударник. Внутренний корпус расположен во внешнем корпусе и может перемещаться вдоль него. Между внутренним и внешним корпусами расположена пружина (30) для натяжения кожи, прижимающая выходное отверстие шприца к коже животного или человека. Внешний корпус содержит пусковой механизм (32), который взаимодействует с ударником, освобождая инъекционную пружину, при этом вводимая доза и тип инъекции - внутримышечная, внутрикожная или под кожу - определяются размером инъекционной пружины и длиной ударника.
