Abstract

The invention consists of a non-reusable syringe (1) that includes a rod (2) that is capable of reciprocating forward and backward relative to a container (3) whose one end (31) consists of, or can interact with, a needle (11), and whose opposite end (32) is open; a piston (12) that can interact with the end of the rod that protrudes into the container; a means (13) for connecting and disconnecting the piston from the end of the rod; at least two guide and glide surfaces (22a, 22b) that have a longitudinal orientation along the edges of the rod. Said means (13) for connecting and disconnecting the piston from the rod is made up of an abutment (21) on the end of the rod that extends towards the needle, which abutment belongs to the support and/or glide surfaces that are arranged to interact with corresponding support and glide surfaces on the piston (12). Rotation of said rod (2) is prevented by a means of control (4) in the container. Said means of control (4) is made up of at least two embossments in an external surface of said container's jacket. Each embossment forms a guide and glide surface in the inner surface of said container's jacket. The guide and glide surfaces of said rod are arranged to run towards, or adjacent and relative to, the guide and glide surfaces of said container.
