The specific embodiment
As shown in Figure 1, described automatic extracting serum or blood plasma vacuum test tube, comprise a former pipe 1, be provided with pillar 3 in inner sleeve 2 and the plural former pipe in the former pipe 1, pillar 3 is supporting inner sleeve 2 in the former pipe, and the bottom of inner sleeve 2 has fluid hole 4, the bottom of inner sleeve 2 is provided with filtering material 5, the top of inner sleeve 2 is provided with additive 6, one plugs 7, is blocked in simultaneously on the mouth of pipe of former pipe 1 and inner sleeve 2.
As shown in Figure 2, the outside of described plug 7 can be provided with protective cap 8.
As shown in Figure 3, the front end of described former pipe 1 can be taper.
As shown in Figure 4, described automatic extracting serum or blood plasma vacuum test tube, comprise a former pipe 1, the bottom of former pipe 1 is former pipe thickening part 9, is provided with inner sleeve 2 in the former pipe 1, inner sleeve 2 is being supported in former pipe thickening part 9, the bottom of inner sleeve 2 has fluid hole 4, and the bottom of inner sleeve 2 is provided with filtering material 5, and the top of inner sleeve 2 is provided with additive 6, one plug 7 is blocked on the mouth of pipe of former pipe 1 and inner sleeve 2 simultaneously.
Shown in Figure 6 such as Fig. 5, described plug 7 can replace with aluminum film 10, and described aluminum film 10 is the former pipe 1 of shutoff and inner sleeve 2 (seeing Fig. 5) simultaneously, also can be the difference former pipe 1 of shutoff and inner sleeve 2 (seeing Fig. 6).
As shown in Figure 7, be provided with snap ring 11 between described filtering material 5 and the additive 6, inner sleeve 2 is provided with snap ring projection 12.The technical program only adopts fixedly the time at filtering material, and snap ring and snap ring projection can be fixed filtering material.
