Abstract

The utility model provides a make things convenient for centrifuging tube of serum separating operation, including the centrifuging tube body, still including hugging closely the spacer ring that centrifuging tube body inner wall set up, the upper surface of spacer ring is greater than the conical surface of lower extreme bore for the upper end bore. When the blood serum separation gel is used, the blood serum separation gel is arranged below the spacing ring, the spacing ring is not only beneficial to the downward movement of red blood cells during centrifugation, but also can prevent the upward drift of the blood serum separation gel, and the blood serum separation gel is prevented from being mixed with blood serum to influence the blood serum separation effect. The utility model discloses simple structure, design science, low in production cost help improving the serum separation effect, are worth popularizing and applying.

Description

Make things convenient for centrifuging tube of serum separation operation

Technical Field

The utility model relates to a biomedical detects consumptive material technical field, especially relates to a make things convenient for centrifuging tube of serum separating operation.

Background

The serum separation gel is a material with good physiological inertia, sealing property and thixotropy, is an isolation medium in a blood collection tube for serum biochemical or plasma biochemical test, can completely separate serum (or plasma) from red blood cells to obtain high-quality serum (or plasma), and effectively ensures the accuracy of blood test. After blood collection, blood is subjected to procoagulant or anticoagulation and then is centrifuged by a centrifuge under certain conditions, and because the specific gravity of the serum separation gel is between serum (or blood plasma) and red blood cells, the serum separation gel moves and reverses to between the two components during centrifugation to form a complete and compact inert isolation layer; after centrifugation is finished, serum (or plasma) is positioned above the serum separation gel, and red blood cells are positioned below the serum separation gel. At present serum separation glue is arranged in vacuum test tube more, and this vacuum test tube is mostly the smooth plastics centrifuging tube in surface, and its pipe wall is smooth, and if centrifugal speed is too fast during the centrifugation, serum separation glue can drift to higher position and serum mixture, influences the effect of serum separation, is unfavorable for the transfer and the detection of the serum in later stage. Therefore, the structure of the centrifugal tube is in urgent need to be improved.

SUMMERY OF THE UTILITY MODEL

For solving the defects of the prior art, the utility model provides a centrifuge tube which is convenient for serum separation operation.

The utility model discloses a realize through following technical scheme:

the utility model provides a make things convenient for centrifuging tube of serum separation operation, includes the centrifuging tube body, still includes the spacer ring of hugging closely centrifuging tube body inner wall setting, and the upper surface of spacer ring is greater than the circular conical surface of lower extreme bore for the upper end bore, and the spacer ring of structure helps red blood cell to move downwards as above, can prevent again that serum seperating glue from upwards drifting to influence the separation effect. The spacer ring is arranged at the middle lower part of the centrifuge tube body, and the specific height is flexibly determined according to the volume of the serum separation gel and the volume of the centrifuge tube body. For convenience of use, the centrifuge tube body is preferably a vacuum centrifuge tube body, and serum separation gel is filled below the spacer ring, so that the vacuum blood collection tube capable of directly collecting blood and performing centrifugal separation is formed.

Preferably, a plurality of archs of equipartition on the inner wall of the centrifuging tube body of spacer ring top, the arch of spacer ring top can improve the stirring effect to blood sample to improve separation efficiency. The protrusions can be hemispherical protrusions or columnar protrusions with different lengths, and the columnar protrusions with different lengths are preferred, so that the structure is favorable for achieving a better stirring effect.

More preferably, the spacer ring is a circular ring, and the width of the circular ring is 0.3-1.0 mm.

Further preferably, the width of the ring is 0.5 mm.

More preferred, centrifuging tube body, spacer ring, arch be integral structure, whole structure integrated into one piece.

Most preferred, centrifuging tube body and protruding integrated structure that is, the spacer ring is an independent structure, and spacer ring detachably sets up in the centrifuging tube body.

Compared with the prior art, the utility model discloses simple structure, design science, low in production cost, serum separation glue arrange the spacer ring below in, and the red blood cell moves down when the spacer ring had both helped the centrifugation, can prevent again that serum separation glue from upwards drifting, avoids it to mix with the serum in order to influence serum separation effect, is worth popularizing and applying.
