METHOD AND TOOL FOR FILTRATING SPECIMEN USING SPECIMEN SAMPLING CONTAINER, AND SPECIMEN SAMPLING CONTAINER

摘要

A method of filtrating specimen using a specimen sampling container for filtrating liquid specimen such as blood with a filter member by utilizing a reduction in pressure therein, capable of securely performing filtration without requiring a plug body removal operation, capable of assuring excellent safety, and less causing the mixing of foreign matter. In the specimen sampling container (1), a specimen sampling part (3) storing the filter member (4) is inserted into a specimen storage part (2) reduced in pressure therein and the specimen storage part (2) and the specimen sampling part (3) are air tightly sealed by the plug body (5). The method is characterized in that when the liquid specimen is sampled and filtrated by using the specimen sampling container (1), the liquid specimen such as blood sampled in the specimen sampling part (3) is filtrated by the filter member (4), and when the filtration is suspended, a hollow needle (12) is pierced into the plug body (5) to communicate the specimen sampling part (3) with the atmosphere so as to more increase a pressure inside the specimen sampling part (3) than the atmosphere for re-starting the filtration.
