Abstract:
An injection device consisting of:a needle,a housing/needle holder, andan injection-container,wherein the injection container is made in a form of a bellows, an open end of which is connected with the housing/needle holder, while a bottom of the bellows and a part of the housing/needle holder enveloped by the bellows are provided by locking elements forming a permanent connection preventing extension of the bellows upon completion of an injection, the locking elements made in a form of pairwise interacting elastically deformable hooks with a beveled catch and a female part in a form of a hole with a ledge; andwherein the bottom of the bellows has a partition separating the bellows from external atmosphere, a center of the partition is on a geometric axis of the needle, and a proximal part of the needle is sharpened and protrudes from the housing/needle holder towards the partition, so that the proximal part of the needle pierces the partition upon completion of an injection.
