The disposable syringe, for the injection of a medication or for taking a blood sample, has a hollow body composed of two sections (1a,1b) hermetically bonded to each other using chemically inert materials. The first section (1a) has a hollow zone for a reservoir (3) and a sealed seating (5) for a hypodermic needle (6). A protective shrouding (7) covers the projecting needle with an end wall (11) around the needle point. A membrane (13) forms a sealed barrier between the needle seating and the reservoir. The second section (1b) has a wall (8) to cover the reservoir, and a second distorting wall (9) attached to a piercing unit (9a) to penetrate the membrane. An intermediate wall forms a passage (14) between the reservoir and the needle seating. A lateral closure (10) clamps the needle seating. |
