A polymerization regulating liquid extraction centrifuge tube

Abstract

The present invention discloses a polymerization-regulated liquid-collecting centrifugal tube, comprising an external tube sleeve, an installation cover, a liquid collection tube, and a polymerization-regulating component. After collecting stratified liquid through the liquid collection tube, the present invention drives the movable ring body to move downward by rotating the external driving sleeve, and then drives the floating cone ring to move downward by the connecting cross bar, so that the flexible telescopic tube is compressed downward, and the floating cone ring moves downward to reduce the horizontal area of ​​the liquid surface of the stratified liquid, thereby causing the stratified liquid to polymerize, increasing the height of the stratified liquid, making it more convenient for the liquid collection tube to perform secondary collection, and achieving the purpose of fully collecting the stratified liquid.

Description

Technical Field

[0001] The invention relates to a polymerization regulating type liquid taking centrifugal tube. Background Art

[0002] At present, a liquid collection centrifuge tube is a commonly used medical device, which is mainly used for the detection of some liquid specimens. The liquid in the liquid collection centrifuge tube will be separated into several layers after the centrifugation of the centrifuge. After the centrifugation is completed, the liquid in different layers needs to be taken out separately. The existing centrifuge tube generally includes a liquid collection tube, a mounting cover, and a liquid storage tube. The liquid storage tube is used to store the liquid, and the upper end of the liquid storage tube is connected to the mounting cover, and the liquid collection tube is passed through the mounting cover. After the liquid is layered, it is collected through the liquid collection tube. However, after the layered liquid is aspirated, the height of the liquid surface is small due to the large dispersion area of ​​the liquid surface, so that part of the layered liquid is not aspirated, resulting in insufficient aspiration of the layered liquid, and even insufficient aspiration of the liquid collection tube. Summary of the Invention
