摘要：
The invention relates to a medical device, and especially relates to a device used for collecting a body fluid. The device is a fluid sampling member for a closed body fluid storage device, and comprises an annular sidewall A and an annular sidewall B； a flow guiding channel is formed by the annular sidewall A, and an air discharge channel is formed by the annular sidewall B； the upper portion of the annular sidewall B is not connected with the annular sidewall A, the minimum sectional area of the flow guiding channel is more than or equal to 3 mm<；2>； and less than or equal to 15 mm<；2>；； and the minimum sectional area of the air discharge channel is more than or equal to 3 mm<；2>； and less than or equal to 15 mm<；2>；. The device has the advantages of simplicity in processing, production cost reduction, high production efficiency, and prevention of backflow.本創作一種密閉體液留置器用取液件，包括環形側壁甲和環形側壁乙；環形側壁甲圍合形成導流通道，環形側壁乙圍合形成排氣通道；所述環形側壁乙的上部與所述環形側壁甲不相連，導流通道截面積最小處大於等於3mm2且小於等於15mm2；排氣通道截面積最小處大於等於3mm2且小於等於15mm2。本創作具有加工簡單、生產成本低、生產效率高且可防止回流的優點。
