Title (EN) SYRINGE FILTER STRUCTURE AND SYRINGE INCLUDING SAME
(FR) STRUCTURE DE FILTRE DE SERINGUE ET SERINGUE COMPRENANT CETTE STRUCTURE
(KO) 주사기용 필터 구조체 및 이를 구비한 주사기
Abstract:
(EN) Provided is a syringe filter structure. The syringe filter structure comprises a filter part provided between a cylinder and an injection needle and connected with the injection needle to filter an injection solution, which is introduced through the rear side of the cylinder, when discharging the injection solution through the injection needle coupled to the front side of the cylinder, wherein the filter part has a first fluid passage formed on one side thereof through which the injection solution is introduced and a second fluid passage formed on an opposite side thereof through which the injection solution is discharged from the cylinder, wherein the filter part comprises: a first check valve connected with the cylinder and selectively blocking the first fluid passage to introduce the injection solution into the cylinder through the first fluid passage; a second check valve connected with the injection needle and selectively blocking the second fluid passage to discharge the injection solution from the cylinder through the second fluid passage; a filter member provided in the second fluid passage and filtering the injection solution discharged through the first check valve; and a filter body located between the second check valve and the filter member and coupled with the second check valve on the front side thereof and with the first check valve on the rear side thereof to bring the filter member into close contact with the first check valve.
(FR) L'invention concerne une structure de filtre de seringue. Cette structure de filtre de seringue comprend une partie filtre placée entre un cylindre et une aiguille d'injection et connectée à l'aiguille d'injection pour filtrer une solution d'injection, qui est introduite par le côté arrière du cylindre, lors de l'expulsion de la solution d'injection à travers l'aiguille d'injection raccordée à la face avant du cylindre, la partie filtre présentant sur un de ses côtés un premier passage de fluide à travers lequel la solution d'injection est introduite et sur son côté opposé un second passage de fluide à travers lequel la solution d'injection est expulsée du cylindre, la partie filtre comprenant : un premier clapet anti-retour connecté au cylindre et bloquant de façon sélective le premier passage de fluide pour introduire la solution d'injection dans le cylindre à travers le premier passage de fluide; un second clapet anti-retour connecté à l'aiguille d'injection et bloquant de façon sélective le second passage de fluide pour expulser la solution d'injection du cylindre à travers le second passage de fluide; un élément filtre disposé dans le second passage de fluide et filtrant la solution d'injection expulsée à travers le premier clapet anti-retour; et un corps de filtre situé entre le second clapet anti-retour et l'élément filtre et raccordé au second clapet anti-retour sur son côté avant et au premier clapet anti-retour sur son côté arrière pour amener l'élément filtre en contact étroit avec le premier clapet anti-retour.
(KO) 주사기용 필터 구조체가 제공된다. 주사기용 필터 구조체는 실린더의 전방에 결합된 주사바늘을 통해 후방으로 유입된 주사액을 배출시킬 때 필터링하기 위해 실린더와 주사바늘 사이에 설치되고 주사바늘과 연결되며, 일측에는 주사액이 유입되는 제1 유체 경로가 형성되고, 타측에는 실린더로부터 주사액이 배출되는 제2 유체 경로가 형성된 필터부를 포함하되, 필터부는 실린더와 연결되고 제1 유체 경로를 선택적으로 막아 제1 유체 경로를 통해 실린더 내부로 주사액을 유입시키는 제1 체크밸브, 주사바늘과 연결되고, 제2 유체 경로를 선택적으로 막아 제2 유체 경로를 통해 실린더 외부로 주사액을 배출시키는 제2 체크밸브, 제2 유체 경로 상에 설치되며 제1 체크밸브를 지나 배출되는 주사액을 필터링하는 필터부재 및 제2 체크밸브와 필터부재 사이에 위치하고, 전방부는 제2 체크밸브와 결합되고, 후방부는 제1 체크밸브와 결합되어 필터부재를 제1 체크밸브에 밀착시키는 필터바디를 포함한다.
