ABSTRACT:
A blood collecting tube comprises a tubular member made of synthetic resin which has an open end and a closed bottom, and a closure member which is for closing the open end of the tubular member and allows a puncture needle to pierce therethrough, the interior of said blood collecting tube being kept under reduced pressure, said tubular member being essentially made of a polyester resin mixture of a polyester resin mainly based on a ethylene glycol and terephthalic acid and a polyester resin mainly based on ethylene glycol and isopthalic acid. The tubular member of this blood collecting tube can be suitably made by injection molding and has high gas barrier properties so that the capability of collecting blood decreases little with time.
