摘要：
Provided is a filter structure for a syringe. The filter structure for a syringe comprises a filter unit installed within a cylinder and connected to a needle coupled to the front of the cylinder in order to perform filtering when an injection solution introduced into the cylinder through the rear thereof is discharged through the needle, wherein a second fluid passage is formed outside a first fluid passage so as to prevent the first fluid passage, through which the injection solution is introduced, from overlapping with the second fluid passage through which the injection solution is discharged from the cylinder, and the filter unit comprises: a first check valve that is connected with the needle and blocks the second fluid passage to introduce the injection solution into the cylinder through the first fluid passage； a second check valve that blocks the first fluid passage to discharge the injection solution from the cylinder through the second fluid passage； a filter member installed on the second fluid passage to perform filtering on the injection solution discharged through the second check valve； and a filter body located between the first check valve and the filter member and coupled to the first check valve at the front thereof and to the second check valve at the rear thereof to bring the filter member close to the second check valve.L'invention concerne une structure de filtre destinée à une seringue. La structure de filtre pour seringue comprend une unité filtre installée à l'intérieur d'un cylindre et reliée à une aiguille couplée à l'avant du cylindre pour mettre en oeuvre un filtrage lorsqu'une solution d'injection, introduite dans le cylindre par l'arrière de celui-ci, est déchargée à travers l'aiguille ； un second passage de fluide est formé à l'extérieur d'un premier passage de fluide pour empêcher que le premier passage de fluide, par lequel la solution d'injection est introduite, n'interfère avec le second passage de fluide par lequel la solution
