PLASMA COLLECTING IMPLEMENT

Japanese Patent JP3685283

B2

PROBLEM TO BE SOLVED: To make it possible to easily and surely collect the blood of the amt. necessary for analysis from a blood vessel by housing a blood filter material laminated with glass fiber filter paper and a microporous film into a holder having a blood inlet and a plasma outlet, connecting a blood taking needle to this blood inlet and providing the plasma outlet side with a plasma receiving vessel.
SOLUTION: A holder body 1 is formed to a cylindrical shape of two stages consisting of a small-diameter part and large-diameter part over the entire part. The plasma receiving vessel 12 and the juncture to the suction side are formed in the upper part of this body and a housing chamber 11 of the blood filter material including the glass fiber filter paper is formed in the lower part. A flange 13 for connection to a cap 2 is formed at the bottom end of the holder body 1 and an inlet of a plasma passage 14 is formed near the one side of the top surface of the housing chamber 11. The upper part of the outlet of the plasma passage 14 is provided with eaves 16 and the rear surface of the eaves 16 is formed to an arc shape, by which the gushing upward of the flowing out plasma is prohibited. The top end of the holder body 10 is opened as a suction port 18 to which a suction means is connected. The cap 2 is provided with a nozzle-like blood supplying port 24.
