Movably clamping type liquid collecting centrifugal tube

Abstract

The invention discloses a movably clamping type liquid collecting centrifugal tube. The movably clamping type liquid collecting centrifugal tube comprises a liquid storage tank, an upper cover, a liquid extracting tube, a lifting mechanism, a mounting block and a retractable bag, wherein the upper cover is mounted at the upper end of the liquid storage tank; one side of the liquid storage tank isprovided with a mounting groove; the lifting mechanism is composed of a support screw, a moving block, a driving plate and a connecting ring; the mounting block is a flat cylindrical structure and formed by splicing two half-cylinders, and the two half-cylinders are provided with longitudinal semicircular channels and transverse semicircular ring grooves which are corresponding in position; the middle of each longitudinal semicircular channel extends perpendicularly into the corresponding half-cylinder to form the corresponding communicated transverse semicircular ring groove; the outside of the liquid extracting tube is provided with ring-shaped teeth which are clamped and fixed by the transverse semicircular ring grooves of the half-cylinders. According to the movably clamping type liquid collecting centrifugal tube, the liquid extracting tube is firmer in connection, is limited both longitudinally and transversely and further is convenient to dismount.

Description

technical field [0001] The invention relates to a liquid-taking centrifuge tube with movable clamping tube body, in particular to a liquid-collecting tube installation structure of the liquid-taking centrifuge tube. Background technique [0002] At present, the 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. Existing centrifuge tubes generally include a liquid collection tube, a mounting plate, and a liquid storage tank; the liquid storage tank is used to store liquid, and the liquid collection tube is installed in the liquid storage tank through the mounting plate. However, there is a problem with this structure. The liquid collection tube is generally directly plugged into the mounting plate, a...

Problems solved by technology

Existing centrifuge tubes generally include a liquid collection tube, a mounting plate, and a liquid storage tank; the liquid storage tank is used to store liquid, and the liquid collection tube is installed in the liquid storage tank through the mounting plate. However, there is a problem with this structure. The liquid collection tube is generally directly plugged into the mounting plate, and the connection is not stable. Because the liquid collection tube needs to be removed at any time, the liquid collection tube and the mounting plate cannot be integrated. Fixed, so it is necessary to develop a liquid collection tube installation structure that is not only stable but also easy to disassemble; in addition, the height of the liquid collection tube cannot be adjusted, and sometimes the liquid level drops before the liquid collection tube collects enough It is out of the bottom of the liquid collection tube, so a centrifuge tube that can adjust the height of the liquid collection tube is needed
