The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.
Referring to figs. 1 through Fig. 3, preferred embodiment of the present utility model provides a kind of blood taking tube, comprises test tube 4, plug 3 and compound tube lid 10, and compound tube lid 10 cooperates for sealing test tube 4 with plug 3.Particularly, compound tube lid 10 comprises that pipe cover 1 and diaphragm seal 2, and pipe cover 1 top and is provided with hole 12, and diaphragm seal 2 covers 1 and is connected to seal to be positioned at and manages the hole of covering on 1 12 with managing.Plug 3 is positioned at pipe and cover 1, and plug 3 is provided with and is beneficial to the concave part 21 that pierces through and concave part 21 and to manage the hole 12 of covering 1 top corresponding, and preferably, hole 12 is positioned to manage covers 1 center of top.Cover 1 diaphragm seal that is connected 2 with pipe and will manage the hole covered on 1 12 and seal, thereby having avoided being arranged in manages the concave part 31 that covers on 1 the plug 3 and be directly exposed to air, the concave part 31 of having eliminated plug 3 is vulnerable to pollute the situation that causes the generation of blood sampling accident.
Preferably, diaphragm seal 2 covers on 1 by welding or be bonded in pipe, will be positioned at hole 12 sealings that pipe covers 1 top.
With reference to Fig. 2, manually tear diaphragm seal 2 in use for convenience, diaphragm seal 2 also is provided with the protuberance of being convenient to grip 21.
With reference to Fig. 1 and Fig. 3, pipe covers 1 and comprises pipe tegmental wall 11, and the inside of pipe tegmental wall 11 is provided with boss 111 is positioned at pipe tegmental wall 11 inner and upper with formation upper chamber 13.Boss 111 can be along the inwall circumference of pipe tegmental wall 11 and extends internally, and also can be the salient point that extends internally along the inwall of pipe tegmental wall 11.Formed step surface 111a between the inwall of boss 111 and pipe tegmental wall 11.Plug 3 comprises tight plug hat 33 of filling upper chamber 13, and plug hat 33 is extended with the plug neck 32 that diameter diminishes downwards, makes that filling in the space 111b and the test tube 4 that form between neck 32 and the boss 111 can closely cooperate.Plug hat 33 is filled in to cooperate in the upper chamber 13 and with the step surface 111a of boss 111 and has guaranteed sealing effectiveness.For the ease of blood sampling, state generally is evacuated in the test tube 4.
