Example (b):
referring to fig. 1-3, the present invention provides a technical solution: an anti-pollution test tube for a clinical laboratory comprises a test tube body 1 and a sealing cover 3 sleeved on the top of the test tube body 1, wherein a liquid inlet pipe 5 is arranged on the sealing cover 3, the liquid inlet pipe 5 is used for externally acting on blood entering the test tube body 1, and the sealing cover 3 is sealed by a rubber plug;
the upper side of the outer wall of the liquid inlet pipe 5 is sleeved with a movable sleeve 6, the lower side of the front wall of the movable sleeve 6 is provided with a locking groove 7, a locking assembly 8 matched with the locking groove 7 is arranged at a corresponding position on the outer wall of the liquid inlet pipe 5, and the locking or unlocking effect of the locking groove 7 and the locking assembly 8 enables the connection between the liquid inlet pipe 5 and the movable sleeve 6 to be locked or not to be locked;
the hasp subassembly 8 includes locating pin 82 of spiro union on the outer wall of feed liquor pipe 5, has cup jointed spacing board 81 and the torsional spring 83 of turning round on locating pin 82's the outer wall, and the both ends of torsional spring 83 are connected with spacing board 81, feed liquor pipe 5 of turning round respectively, and 6 outer wall bottoms of movable sleeve are provided with and are connected with spacing retaining ring 9 with spacing board 81 looks adaptation of turning round, and the inner chamber upper end of movable sleeve 6 has supported by the support bar and has closed plate 11, and the top of movable sleeve 6 has cup jointed sample syringe needle 12.
Be connected with air pressure regulation mouth 4 on the closing cap 3, and the spiro union has end cover on the air pressure regulation mouth 4, through the setting of air pressure regulation mouth 4, when opening, conveniently business turn over blood, avoid inside high pressure to prevent the condition that advances blood, inside negative pressure prevents to bleed.
