Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the longitudinal cross-section sectional view of the utility model annular groove.
Specific implementation mode
As depicted in figs. 1 and 2, disposable vacuum blood collection tube, including liquid storage pipe 1, plasma filtering device and casing 2,
1 upper end opening lower end closed of liquid storage pipe, casing 2 is sheathed on 1 upper end of liquid storage pipe, and casing 2 is connected by screw thread and the rotation of liquid storage pipe 1
It connects, plasma filtering device includes ring holder 3, screen pipe 4 and plasmapheresis net 5, screen pipe 4 and 3 lower end of ring holder
Face is fixedly connected, and 4 upper and lower ends of screen pipe are opening setting, and the outer diameter of screen pipe 4 is less than the internal diameter of liquid storage pipe 1, annular branch
The outer diameter of support 3 is equal to the outer diameter of liquid storage pipe 1, and the internal diameter of ring holder 3 is less than the internal diameter of liquid storage pipe 1, and ring holder 3 covers
It is coaxially disposed set on 1 upper end of liquid storage pipe and with liquid storage pipe 1, and it is close that elasticity is equipped between 1 upper surface of ring holder 3 and liquid storage pipe
Seal washer 6, screen pipe 4 are located in liquid storage pipe 1, and plasmapheresis net 5 is horizontally placed in screen pipe 4；2 upper end of casing is equipped with to set
The collar stop 7 that 2 inside of pipe extends, collar stop 7 are coaxially disposed with casing 2, the outer diameter of the outer diameter and casing 2 of collar stop 7
Identical, the internal diameter of collar stop 7 is less than the internal diameter of ring holder 3, and the medial surface of collar stop 7 is equipped in collar stop 7
