Title
(EN) SYRINGE PROVIDED WITH FILTER
(FR) SERINGUE MUNIE D'UN FILTRE

Abstract
(EN)
The present invention relates to a syringe provided with a filter which, during an injection process, filters ampoule pieces introduced into the syringe via a syringe needle when the syringe is filled with an ampoule injection, thus preventing the pieces from entering a human body. The present invention provides a syringe provided with a filter which filters in a syringe needle coupling part (100) impurities included in an injection, wherein the filter (200) comprises: a body part (210) which has a rear opening (211) and is fixedly inserted into the syringe needle coupling part; a filter plate (220) which is attached to the rear opening of the body part and filters impurities included in the injection; and a gasket (230) comprising a first elastic portion (231) which is closely connected between the front end of the body part and the syringe needle coupling part and provides an injection inflow path that avoids the filter plate, while being elastically deformed inward by the inflow pressure of the injection, and a second elastic portion (232) which provides an injection discharge path in communication with the filter plate, while being elastically deformed outward by the discharge pressure of the injection.

La présente invention concerne une seringue munie d'un filtre qui, pendant un processus d'injection, filtre des morceaux d'ampoule introduits dans la seringue par l'intermédiaire d'une aiguille de seringue lorsque la seringue est remplie par un fluide provenant d'une ampoule injectable, empêchant ainsi les pièces d'entrer dans un corps humain. La présente invention concerne une seringue pourvue d'un filtre qui filtre, dans une partie de raccordement d'aiguille de seringue (100), des impuretés incluses dans un fluide d'injection, le filtre (200) comprenant : une partie de corps (210) qui est dotée d'une ouverture arrière (211) et qui est insérée de manière fixe dans la partie de raccordement d'aiguille de seringue ; une plaque de filtre (220) qui est fixée à l'ouverture arrière de la partie de corps et qui filtre des impuretés contenues dans le fluide d'injection ; et un joint d'étanchéité (230) qui comprend une première partie élastique (231) qui est étroitement reliée entre l'extrémité avant de la partie de corps et la partie de raccordement d'aiguille de seringue, et qui fournit une voie d'entrée de fluide d'injection qui évite la plaque filtrante, tout en étant élastiquement déformée vers l'intérieur par la pression d'entrée de fluide d'injection, et une seconde partie élastique (232) qui fournit une voie d'évacuation de fluide d'injection en communication avec la plaque filtrante, tout en étant élastiquement déformé vers l'extérieur par la pression d'évacuation du fluide d'injection.

본 발명은 앰플의 주사액을 주사기에 충진할 경우에 주사바늘을 통해 주사기 내부로 유입된 앰플 조각들이 주사과정에서 필터링되어 인체로 유입되지 않도록 하는 필터를 구비한 주사기에 관한 것이다. 본 발명은 주사바늘 결합부(100) 내에서 주사액에 포함된 이물질을 필터링하는 필터를 구비한 주사기에 있어서; 상기 필터(200)가 후방개구(211)를 가지며 주사바늘 결합부의 내부에 끼움 고정된 몸체부(210)와; 상기 몸체부의 후방개구에 부착되어 주사액에 포함된 이물질을 걸러주는 필터판(220)과; 상기 몸체부의 전단과 주사바늘 결합부 사이에 밀착 결합되며, 주사액 유입압력에 의해 내측으로 탄성 변형되면서 상기 필터판을 회피하는 주사액유입유로를 제공하는 제1탄성부(231)와, 주사액 배출압력에 의해 외측으로 탄성 변형되면서 상기 필터판과 연통되는 주사액배출유로를 제공하는 제2탄성부(232)를 구비한 가스켓(230)을 포함한다.
