The present invention refers to an easy to use and more cost effective medication injector. The injector comprises a fluid container (1) made, preferably, of one bent, or two straight, edge heat-sealed neutral, flexible, pressure resistant and autoclavable plastic films, containing, at the discharge side, a rigid plastic tube (2) with reinforcement wings (3), in whose distal end is attached a needle (4), tightly enclosed in a plastic tube (5), closed at its distal end (6), the set being enclosed in an air-tight envelope (7) with rims (8). For large volumes infusion, the container (1) is attached to an infusion tubing (9) with a simple drip chamber (40) and an optional clamp (11) and a three-way stopcock (41) adapted to connect a syringe (42) for an initial bolus in a biphasic administration. For large volumes pressure injections, the container (1) is placed between pressing plates (14and 17) respectively attached to a lower (13) and upper (15) elements, both connected by the main link (16).

[ I claim:] [1.] A medication injector, comprising:a fluid container having a discharge end, said container formed of a folded plastic film sealed along its edges forming a fluid compartment;a rigid ring fixed at the discharge end of said container and in communication with said fluid compartment, said ring having reinforcement wings;a injection needle having proximal and distal ends, fitted at said proximal end to said rigid ring and thereby being in fluid communication with said fluid compartment;a plastic tube sealed at its distal end, tightly enclosing said injection needle, and acting to prevent leakage of liquid through said distal end of said injection needle; anda protective envelope formed around said injection needle and said plastic tube.
