Provided is a preparation syringe integrated structure, comprising a stretchable plunger (1), a syringe cylinder (2), a syringe needle (3), an exposed rubber plug (7), a sealing piece (8), a built-in rubber plug (9), a sealing rubber plug (12) and a linking rubber plug (14), wherein one end of the syringe cylinder (2) is provided with the stretchable plunger (1), and the other end thereof is provided with a clamping post (11)； the exposed rubber plug (7) is provided on one side, away from the syringe cylinder (2), of the stretchable plunger (1)； the built-in rubber plug (9) is provided inside the syringe cylinder (2)； and scale marks (10) are provided on a circumferential surface of the syringe cylinder (2). With a medicine storage bottle and a syringe being designed as an integrated structure, intermediate links can be reduced so as to reduce the waste of a liquid medicine due to insufficient suction and overflowing of the liquid medicine, and to also reduce the professional risks of medical workers and thus reduce the potential injury of a patient caused by particles formed due to repeated punctures. The stretchable plunger structure designed in a matching manner can reduce the overall length so as to facilitate the puncturing operation. Using a syringe needle with an epsilon-shaped cross section can effectively avoid the waste of the liquid medicine.L'invention concerne une structure intégrée de seringue de préparation, comprenant un piston extensible (1), un cylindre de seringue (2), une aiguille de seringue (3), un bouchon en caoutchouc exposé (7), une pièce d'étanchéité (8), un bouchon en caoutchouc intégré (9), un bouchon en caoutchouc d'étanchéité (12) et un bouchon en caoutchouc de liaison (14), une extrémité du cylindre de seringue (2) étant pourvue du piston extensible (1), et l'autre extrémité de celui-ci étant pourvue d'un montant de serrage (11)； le bouchon en caoutchouc exposé (7) est disposé sur un côté, à l'opposé du cylindre de seringue (2), du pis
