Detailed Description
The present invention will be further described with reference to fig. 1 to 4.
The first embodiment is as follows:
the utility model relates to a blood sampling tube, it includes the pipe body, and the external diameter of pipe body is the same with conventional blood sampling tube external diameter, has blood sampling chamber 11 and filling part in this body of pipe, and filling part is arranged in the space except blood sampling chamber in the filling tube body. The blood collection cavity 11 is a vacuum cavity, the blood collection cavity 11 is positioned at the middle upper part in the tube body, and the filling part is additionally arranged to increase the side wall thickness and the bottom thickness of the tube body so that the volume of the blood collection cavity 11 is smaller than that of the tube body.
The middle part of the blood collecting cavity 11 is provided with separating gel, after blood collection, serum is remained at the upper part of the blood collecting cavity 11, and substances such as blood cells, red blood cells and the like are separated to the lower part of the blood collecting cavity 11.
The filling part comprises a first part 12 and a second part 13, the filling part is a vacuum cavity, and then the filling part and the blood sampling cavity are separated by a glass wall, or the filling part is designed into a solid structure. The first part 12 is positioned below the blood collection cavity 11, and the first part 12 is additionally arranged, so that the depth of the blood collection cavity 11 is smaller than the height of the tube body. The second portion 13 is disposed around the blood collection chamber 11, and the second portion 13 is added so that the inner diameter of the blood collection chamber 11 is smaller than the outer diameter of the tube body.
The opening of the pipe body is provided with a cover body, the cover body comprises a first cover body 14 and a second cover body 15,
the first cover 14 is located in the second cover 15, the first cover 14 is a rubber member, the lower portion of the first cover 14 is inserted into the blood collection chamber 11, and the inner wall of the second cover 15 contacts with the outer wall of the tube body. The first cover 14 is used to seal the pipe body, and the second cover 15 is used to fix the first cover 14 to prevent it from falling off.
A second supporting portion 16 is formed on the upper portion of the inner wall of the second cover 15, the second supporting portion 16 is a hole shoulder structure, a first limiting portion is formed on the upper portion of the outer wall of the first cover 14, and the first limiting portion is a ring of protruding structure formed around the outer wall of the first cover 14.
