The technical scheme adopted by the invention is as follows: a vacuum negative pressure blood collection tube comprises a vacuum negative pressure tube body (1), wherein a sealing plug (2) for sealing an opening part at the upper end of the vacuum negative pressure tube body (1) and a tube cover (3) which is positioned outside the sealing plug (2) and connected to the vacuum negative pressure tube body (1) are arranged at the opening part;
the upper surface of the pipe cover (3) is opened, the side surface of the pipe cover (3) is provided with an external thread, and a pipe cap (4) provided with an internal thread is connected to the pipe cover (3) in a threaded manner to form protection on the sealing plug (2);
the outer surface of the vacuum negative pressure pipe body (1) is sleeved with an anti-skidding sleeve (5);
the vacuum negative pressure pipe is characterized in that scales are arranged on the surface of the vacuum negative pressure pipe body (1), a slit is arranged in the longitudinal direction of the anti-slip sleeve (5) to expose the scale part, and the anti-slip sleeve (5) is transparent.
A plurality of annular grooves (6) are discontinuously formed in the side surface of the sealing plug (2), an annular cavity (21) is formed in the sealing plug (2) along the axial direction, and air holes matched with the annular cavity (21) are formed in the surface of the sealing plug (2).
The vacuum negative pressure pipe is characterized in that a convex clamping groove (11) is formed in the inner surface of the vacuum negative pressure pipe body (1), a convex ring (22) clamped in the clamping groove (11) is correspondingly arranged on the sealing plug (2), and the convex ring (22) is in close contact with the clamping groove (11) when the annular cavity (21) is inflated.
The invention has the advantages that: according to the invention, through the arrangement of the pipe cover and the pipe cap, when the pipe cap is not used, the pipe cap protects the sealing plug, so that the sealing plug is prevented from being polluted by impurities, dust and the like; furthermore, the anti-slip sleeve is arranged, so that the friction force between an operator and the collection blood vessel is increased during blood collection operation, and the collection blood vessel is prevented from slipping off; meanwhile, due to the arrangement of the sealing plug annular cavity, the sealing plug and the vacuum negative pressure pipe body can form tight fit when the annular cavity is arranged and inflated, so that the sealing performance is ensured, and a certain gap can be formed between the sealing plug and the vacuum negative pressure pipe body when the annular cavity is deflated, so that the sealing plug can be easily taken out from the vacuum negative pressure pipe body.

Detailed Description
A vacuum negative pressure blood collection tube comprises a vacuum negative pressure tube body 1, wherein a sealing plug 2 for sealing the upper port part of the vacuum negative pressure tube body 1 and a tube cover 3 which is positioned outside the sealing plug 2 and connected to the vacuum negative pressure tube body 1 are arranged at the upper port part of the vacuum negative pressure tube body 1;
the upper surface of the tube cover 3 is provided with an opening, the side surface of the tube cover 3 is provided with an external thread, and a tube cap 4 provided with an internal thread is connected to the tube cover 3 in a threaded manner to form protection on the sealing plug 2;
the outer surface of the vacuum negative pressure pipe body 1 is sleeved with an anti-skid sleeve 5;
the vacuum negative pressure pipe body 1 surface is provided with the scale, anti-skidding cover 5 longitudinal direction is provided with the jag will the scale part exposes, anti-skidding cover 5 is transparent.
