Abstract: front page image
(EN)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.
(FR)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 d'injection est déchargée du cylindre. L'unité filtre comprend : un premier clapet de non-retour, qui est relié à l'aiguille et bloque le second passage de fluide afin de permettre l'introduction de la solution d'injection dans le cylindre par le premier passage de fluide ; un second clapet de non-retour, qui bloque le premier passage de fluide afin que la solution d'injection provenant du cylindre soit déchargée par le second passage de fluide ; un élément filtre, installé sur le second passage de fluide afin de filtrer la solution d'injection déchargée par le second clapet de non-retour ; et un corps de filtre, qui se situe entre le premier clapet de non-retour et l'élément filtre et est couplé au premier clapet de non-retour à l'avant de celui-ci, et au second clapet de non-retour à l'arrière de celui-ci pour amener l'élément filtre à proximité du second clapet de non-retour.
(KO)주사기용 필터 구조체가 제공된다. 주사기용 필터 구조체는 실린더의 전방에 결합된 주사바늘을 통해 후방으로 유입된 주사액을 배출시킬 때 필터링하기 위해 실린더 내부에 설치되어 주사바늘과 연결되며, 주사액이 유입되는 제1 유체 경로가 실린더로부터 주사액이 배출되는 제2 유체 경로와 겹치지 않도록 제2 유체 경로가 제1 유체 경로의 외주부에 형성된 필터부를 포함하되, 필터부는 주사바늘과 연결되고, 제2 유체 경로를 막아 제1 유체 경로를 통해 실린더 내부로 주사액을 유입시키는 제1 체크밸브, 제1 유체 경로를 막아 제2 유체 경로를 통해 실린더 외부로 주사액을 배출시키는 제2 체크밸브 및 제2 유체 경로 상에 설치되며 제2 체크밸브를 지나 배출되는 주사액을 필터링하는 필터부재 및 제1 체크밸브와 필터부재 사이에 위치하고, 전방부는 제1 체크밸브와 결합되고, 후방부는 제2 체크밸브와 결합되어 필터부재를 제2 체크밸브에 밀착시키는 필터바디를 포함한다,
