Problems solved by technology

Even if the liquid taking part is equipped with an exhaust channel, during the liquid guiding process, the liquid will still flow to the exhaust port to block the exhaust port, resulting in liquid retention
In addition, the liquid extraction part is equipped with an exhaust channel, but the production and processing are more complicated, the cost is high, the production efficiency is low, and the speed of diversion is not fast enough

Abstract

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.

Description

Technical field [0001] The present invention relates to medical equipment, in particular to a device for collecting body fluids. Background technique [0002] The liquid taking part for a closed body fluid retainer in the prior art has only a diversion channel and no exhaust channel, especially when liquid is poured into a small-caliber container. When the liquid taking part and the connection part of the container are sealed and fitted, liquid retention often occurs. Even if the liquid taking part is provided with an exhaust channel, in the process of liquid guiding, there is still a phenomenon that the liquid will flow to the exhaust port and block the exhaust port, resulting in liquid retention. In addition, the liquid taking part is provided with an exhaust channel, but the production and processing are complicated, the cost is high, the production efficiency is low, and the flow diversion speed is not fast enough. Summary of the invention [0003] The purpose of the presen...
