[0012] Preferably, the diameter of the rubber stopper is larger than the diameter of the through opening.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, by arranging the tube cap, the sleeve ring and the shielding plate to cooperate with each other, the two shielding plates are spliced ​​together, so that the rubber plug in the tube cap can be shielded by the two spliced ​​shielding plates, and then the sleeve ring is pushed up to limit the spliced ​​shielding plates, so as to prevent the shielding plates from moving and exposing the rubber plug. In this way, the rubber plug will not be contaminated during the placement of the vacuum test tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 The vacuum blood collection tube seal shown in the figure comprises a tube cap 1, a rubber plug 4 and a collar 2. The collar 2 is movably sleeved on the surface of the tube cap 1, shielding plates 3 are movably installed on the upper surface of the tube cap 1 and on both sides, and a rubber plug 4 is embedded in the tube cap 1.

[0022] The upper surface of the pipe cap 1 is provided with a limit slide groove 101 at the front and rear, and a through opening 103 is provided on the upper surface of the pipe cap 1. The two side surfaces of the pipe cap 1 are provided with a movable groove 102 near the top. The cooperation between the limit slide groove 101 and the limit slider 302 can assist the smooth movement of the shielding plate 3; the inner two side surfaces of the collar 2 are provided with a movable block 201 fixedly installed at the bottom, and the movable block 201 is embedded in the movable groove 102. The cooperation between the movable block 201 and the movable groove 102 can assist the vertical lifting of the collar 2; the shielding plate 3 It is semicircular, and a tapered opening 301 is fixedly installed on the upper surface of the baffle plate 3 at the center of the circle, and a limiting slider 302 is fixedly installed on the lower surface of the baffle plate 3 near both sides; the diameter of the baffle plate 3 is smaller than the inner diameter of the collar 2, and the collar 2 is movably connected to the pipe cap 1 through the moving block 201; the limiting slider 302 is embedded in the limiting slide groove 101, and the baffle plate 3 is movably connected to the pipe cap 1 through the limiting slider 302, and the baffle plate 3 can block the rubber plug 4 to prevent foreign matter from contacting the rubber plug 4; the diameter of the rubber plug 4 is larger than the diameter of the through opening 103.

[0023] It should be noted that the utility model is a vacuum blood collection tube seal. When in use, the two shielding plates 3 are spliced ​​together, so that the rubber plug 4 in the tube cap 1 can be shielded by the two spliced ​​shielding plates 3, and then the ring 2 is pushed up to limit the spliced ​​shielding plates 3 to prevent the shielding plates 3 from moving and exposing the rubber plug 4. In this way, the rubber plug 4 will not be contaminated during the placement of the vacuum test tube. When blood collection is required, the ring 2 is pressed to make the ring 2 drop, and then the bleeding end of the needle is inserted into the tapered mouth 301 of the shielding plate 3. As the bleeding end of the needle is continuously inserted, the two shielding plates 3 will be pushed open until the bleeding end of the needle passes through the rubber plug 4 and is inserted into the tube body.
