Abstract
(EN)
The present invention relates to a metal screen filter for separating cancer cells from blood. The metal screen filter of the present invention is formed with a plurality of filtration holes for filtering cancer cells, such that the gap between two neighboring filtration holes of the plurality of filtration holes is formed to be 45 - 65 % the diameter of a cancer cell, and is installed into a passage having blood flow containing both cancer cells and non-target cells. The diameter of a filtration hole for filtering a cancer cell is 5 - 25 ㎛. According to the present invention, cancer cells can be efficiently and easily separated and collected from large amounts of blood. Additionally, the collection rate of live cancer cells is improved by smooth emission of cancer cells out of a catheter by flow of solution.

L'invention concerne un filtre à tamis métallique pour séparer des cellules cancéreuses présentes dans du sang. Le filtre à tamis métallique selon l'invention est formé d'une pluralité d'orifices de filtration servant à filtrer des cellules cancéreuses, de sorte que l'espace séparant deux orifices de filtration adjacents soit formé pour être égal à 45 à 65% du diamètre d'une cellule cancéreuse, et est monté dans un passage présentant un flux de sang contenant à la fois des cellules cancéreuses et des cellules qui ne sont pas des cellules cibles. Le diamètre d'un orifice de filtration servant à filtrer une cellule cancéreuse est compris entre 5 et 25 ㎛. Selon l'invention, les cellules cancéreuses peuvent être séparées et collectées efficacement et facilement dans de grandes quantités de sang. En outre, le taux de collecte de cellules cancéreuses vivantes est accru par l'émission régulière de cellules cancéreuses hors d'un cathéter par écoulement de solution.

본 발명은 혈액으로부터 암세포를 분리하기 위한 금속 스크린필터를 개시한다. 본 발명의 금속 스크린필터는 암세포와 비표적세포를 포함하고 있는 혈액이 흐르는 통로에 설치되어 있으며, 암세포의 여과를 위하여 복수의 여과구멍들이 형성되어 있고, 복수의 여과구멍들 중 인접하는 두 여과구멍들 사이의 간격이 암세포의 직경에 대하여 45~65%로 형성되어 있다. 여과구멍들의 직경은 암세포의 여과를 위하여 5~25㎛으로 형성되어 있다. 본 발명에 의하면, 다량의 혈액으로부터 암세포를 간편하고 효율적으로 분리하여 채집할 수 있다. 또한, 솔루션의 흐름에 의하여 암세포를 도관 밖으로 원활하게 배출하여 살아 있는 암세포의 채집율을 향상시킬 수 있다.
