POROUS REAGENT DISCHARGING SYSTEM AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To obtain an improved system for separating a plasma or a serum from a whole blood by constituting of a matrix of a hydrophilic sintered porous substance associated with at least one type of red blood cell coagulant. SOLUTION: The system 10 comprises a housing 12 having an inlet 13 and an outlet hole 16. A device 17 is placed in the housing 12 and the device 17 contains a porous polyethylene matrix 18. The matrix contains a coagulant and is formed in a cylindrical state having a diameter of 3.5 mm and a height of 5 mm. Accurate shape and size give an influence to a retaining time and an efficiency. A paper matrix 20 is placed in the housing 12. The matrix 18 has an inlet 14 and an outlet 15 and has a liquid receiving relation to the matrix 20. The matrix 20 and the matrix 18 may contain a reagent necessary for analyzing a selected object to be analyzed for the blood.
