However, the blood cells are at the bottom of the serum separation tube. If a sampling needle is used to pass through the serum and the separation gel to reach the blood cells, the sampling needle will inevitably bring a small amount of serum and separation gel molecules into the blood cells, which will undoubtedly affect the blood cell test. the accuracy of

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] The serum separation tube with selective extraction function is composed of a conduit sealing plug 1 , a splash cap 2 , a rubber plug 3 , a conduit 4 , a main pipe 5 and a bottom plug 6 . Wherein, the main pipe 5 is a glass tube with an open upper end and a closed lower end. A cylindrical bottom plug 6 is bonded to the center of the inner bottom surface of the main pipe 5, and the bottom plug 6 is coaxial with the main pipe 5.

[0018] The upper port of the main pipe 5 is plugged with a rubber plug 3, and the middle part of the rubber plug 3 has a vertical through hole. The conduit 4 is a straight pipe, the upper end of the conduit 4 is in the vertical through hole of the rubber plug 3, and the outer wall of the upper end of the conduit 4 is bonded as a whole with the inner wall of the vertical through hole. The lower end of the conduit 4 is sle...

Abstract

The invention relates to the technical field of vacuum blood collection, in particular to a serum separating tube with a selective sucking function. The serum separating tube with the selective sucking function consists of a conduit sealing plug, a splash-proof cap, a rubber plug, a conduit, a main tube and a bottom plug, wherein the cylindrical bottom plug is adhered at the center of the inner bottom of the main tube; the rubber plug is plugged into an upper end opening of the main tube; a vertical through hole is formed in the middle part of the rubber plug; the upper end of the conduit is positioned inside the vertical through hole of the rubber plug; and the lower end of the conduit is sleeved at the upper end of the bottom plug and is in interference fit with the bottom plug. The serum separating tube with the selective sucking function can directly sample serum and blood cells; and compared with the conventional ordinary separating tube, the serum separating tube with the selective sucking function has dual functions and brings conveniences for sampling.

Description

technical field [0001] The invention relates to the technical field of vacuum blood collection, in particular to a serum separation tube with selective extraction function. Background technique [0002] In the existing serum separation tube, after the blood sample is drawn and separated by a centrifuge, the blood sample and the separation gel are sequentially divided into three layers of serum, separation gel and blood cells in the tube from top to bottom. In the course of the test, sometimes it is necessary to take serum, and sometimes it is necessary to take blood cells for analysis. Since the serum is in the first layer, the sampling needle can be directly inserted into it for extraction. However, the blood cells are at the bottom of the serum separation tube. If a sampling needle is used to pass through the serum and the separation gel to reach the blood cells, the sampling needle will inevitably bring a small amount of molecules of serum and separation gel into the blo...
