Syringe serving also as an ampule and associated equipment

A syringe device comprising:

• a piston;
• a cylinder portion for accepting said piston therein, said cylinder portion having a tip end;
• said tip end having a frangible seal film and a threaded portion;
• a bellows portion sealingly interconnecting said cylinder portion and said piston in a sealed manner such that said piston is insertable into said cylinder portion and the bellows portion, the piston, and the cylinder portion together form an ampule container for containing a medicinal liquid;
• a needle portion having a needle and accepting said threaded portion of the tip portion;
• and
• said needle portion having an inside projection for breaking said frangible seal film and thereby communicating said needle with said ampule container for passing medicinal liquid therethrough.

A syringe comprising:

• a piston;
• a cylinder portion for accepting said piston therein, said cylinder portion having a tip end with a channel communicating with an interior of said cylinder portion;
• a bellows portion sealingly interconnecting said cylinder portion and said piston in a sealed manner such that said piston is movable into and out of the interior of said cylinder portion, and the bellows portion, the piston, and the cylinder portion together form a container for receiving a liquid through said channel of said tip end upon withdrawal of said piston from the interior of said cylinder portion;
• at least one cylinder wing portion extending from said cylinder portion and defining an aperture;
• and
• said piston having at least one piston wing portion with a projection for engaging said aperture of said at least one cylinder wing portion to hold said piston at a position within the interior of said cylinder portion.

A syringe comprising:

• a piston;
• a cylinder portion for accepting said piston therein, said cylinder portion having a tip end with a channel for communicating with an interior of said cylinder portion;
• a seal occluding said channel;
• a bellows portion sealingly interconnecting said cylinder portion and said piston in a sealed manner such that said piston is movable into and out of the interior of said cylinder portion, and the bellows portion, the piston, and the cylinder portion together form a container for receiving a liquid therein;
• a threaded portion provided on said tip end;
• a needle portion having a needle and accepting said threaded portion of the tip portion;
• and
• said needle portion having an inside projection for breaking said seal and thereby communicating said needle with said container via said channel for passing liquid therethrough.
