The distal blood collection tube provided in the embodiments of the present application will now be described.

Please refer to fig. 1, 3 and 4, which are schematic diagrams of the structure of the distal blood collection tube. The distal blood collection tube comprises a tube body 1 and a tube cover 2; the tube cap 2 includes: the top of the pipe cover body 3 is downwards recessed to form a containing groove 4, and a square through hole 5 is formed in the bottom of the containing groove 4; the leakage preventing plug 6 comprises a plug body 7 inserted into the accommodating groove 4, and a connecting belt 8 for connecting the plug body 7 and the pipe cover body 3. When the anti-leakage device is used, the plug body 7 of the anti-leakage plug 6 is pulled out of the accommodating groove 4, the capillary suction pipe is inserted into the pipe body 1 through the square through hole 5 for blood collection, after the collection is completed, the capillary suction pipe is pulled out, and the plug body 7 of the anti-leakage plug 6 is inserted into the accommodating groove 4, so that sealed storage is realized. The side length of the square through hole 5 is the same as the outer diameter of the matched capillary suction pipe, and four corners of the square through hole 5 are used for exhausting, so that an additional exhaust hole is not required to be processed for exhausting; simultaneously, the capillary suction tube can be well stabilized, and the posture of the capillary suction tube is stable in the collection process, so that the collection is facilitated.

In order to facilitate the extraction of the leakage preventing plug 6, in one embodiment, an extension pulling piece 9 is disposed at an end of the plug body 7 away from the connection belt 8, and the leakage preventing plug 6 can be extracted by pulling the extension pulling piece 9 upwards.

Further, in one embodiment, the outer surface of the tube cover body 3 is provided with anti-slip patterns 10 except for the portion corresponding to the extending pulling piece 9, so that a worker can conveniently hold the tube cover body 3 for rotation, and the extending pulling piece 9 is not prevented from being operated to pull out the anti-leakage plug 6.

In one embodiment, in order to better clamp the upper edge of the pipe body 1, the outer surface of the accommodating groove 4 has a structure with a narrow upper part and a wide lower part. The upper edge of the pipe body 1 enters between the accommodating groove 4 and the pipe cover body 3, so that the tightness is improved.

In order to improve the stability of the combination state of the leakage-proof plug 6 and the pipe cover body 3, an arc-shaped boss 11 is arranged at the top of the pipe cover body 3 outside the accommodating groove 4 and used for limiting the leakage-proof plug 6.

In order to ensure that the pipe cover body 3 and the pipe body 1 are firmly combined, the pipe cover body 3 is matched with the pipe body 1 in a clamping way, specifically, a plurality of protrusions 12 are circumferentially arranged on the inner wall of the pipe cover body 3, and an annular boss 13 matched with the protrusions is arranged on the outer surface of the pipe body 1.

When the pipe body 1 is connected with the pipe cover 2, the pipe cover 2 is pressed down, the annular boss 13 of the pipe body 1 firstly abuts against the second transition slope 16, then the pipe body is extruded to rise to the connecting platform 15 along with the second transition slope 16, then enters the area of the first transition slope 14, and finally is clamped on the first transition slope 14. The advantage of setting up the transition slope is, avoids because there is production error, causes annular boss 13 size to be partial big or partial little to lead to body 1 and tube cap 2 joint too tight or too loose, the blood sample of gathering easily receives the pollution.

Referring to fig. 2, 5 and 6, further, the bottom of the tube cover body 3 is provided with an annular groove 17, and the inner ring of the annular groove 17 is surrounded by a plurality of inverted triangle convex pieces 18; the outer surface of the pipe body 1 is provided with an annular convex ring 19 which is used for being inserted into the annular groove 17, and regular triangle convex pieces 20 which are distributed in a staggered way with the inverted triangle convex pieces 18 are arranged between the annular convex ring 19 and the wall of the pipe body 1. When the pipe body 1 is connected with the pipe cover 2, the inverted triangular convex parts 18 are inserted between the regular triangular convex parts 20 and matched with the bulges 12 and the annular boss 13, so that the pipe body 1 is locked, and the pipe body can be prevented from loosening even jolting in the transportation process. When the pipe cover 2 is opened, the inverted triangle convex part 18 moves upwards under the guiding action of the regular triangle convex part 20, so that the pipe cover 2 is driven to move upwards, and the pipe cover 2 can be easily separated from the pipe body 1.
