Abstract

The invention discloses a centrifugal tube facilitating liquid sampling. The centrifugal tube comprises a tube body, a cap, a stop ring, a fixed disc and liquid suction tubes. The annular stop ring is fixed to the inner wall of the tube body, an internal thread is arranged on the inner wall of the tube body and located above the stop ring, the fixed disc covers the stop ring, the edge of the fixed disc is provided with an external thread matched with the internal thread, the liquid suction tubes with different lengths are fixed to the fixed disc, one end of each liquid suction tube is located below the stop ring, the other end of each liquid suction tube is located above the fixed disc, an annular flange is fixed to the edge of the top of the tube body, and an annular clamping ring is arranged at the bottom of the cap and provided with an annular clamping groove matched with the flange. Due to the fact that the liquid suction pipes with different lengths are arranged in the tube body in advance, liquid can be sampled conveniently after being centrifuged, and liquid sampling is convenient.

Description

【Technical field】 [0001] The invention relates to the technical field of medical instruments, in particular to the technical field of centrifuge tubes. 【Background technique】 [0002] A centrifuge tube is a commonly used medical device, which is mainly used for the detection of some liquid samples. The liquid in the centrifuge tube will be divided into several layers after being centrifuged by the centrifuge. After the centrifugation is completed, the liquid in different layers needs to be taken out separately. The existing centrifuge tubes take out the liquid, especially when taking out the liquid in the middle layer, the steps are cumbersome, which is not conducive to the improvement of work efficiency. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a centrifuge tube that is convenient for taking liquid, which can make the liquid that is separated by centrifugation in the centrifuge tube easy t...
