As preferably, the edge of described concave structure also offers several U-type groove holes uniformly, the rounding diameter in described U-type groove hole is 0.8mm ~ 1.2mm, and the opening in several U-type groove holes all outwardly, the number in described U-type groove hole is three, when when carrying out separation of lymphocytes, the blood sample above plug-in unit and lymph parting liquid is facilitated to carry out exchange of substance.
As preferably, the bottom of described cylindrical structure offers several arcuate sockets uniformly, and the arc degree of depth of described arcuate socket is 1mm, and width is 4mm, and the number of arcuate socket is three, the setting of arcuate socket is used for the sample of centrifuge tube when centrifugal above lymphocyte separation medium and plug-in unit and exchanges.
As preferably, the diameter 1mm larger than the diameter of cylindrical structure of described concave structure, and the inwall of body is close at the edge of concave structure, by larger than the diameter of cylindrical structure for the diameter design of concave structure 1mm, its effect is, also form aperture between such U-type groove hole and body, in centrifugal, lymphocyte separation medium can be split into above plug-in unit by these apertures.
As preferably, the opening in described U-type groove hole contacts with cylindrical structure, and forms a waist-shaped hole.
As preferably, be provided with several stiffening webs in described plug-in unit, the setting of stiffening web serves effect that is stable and that reinforce.
The beneficial effects of the utility model: lymphocyte separation medium is added below plug-in unit and then adds sample more than plug-in unit, can directly make the layering of target lymphocyte above plug-in unit through centrifugal, by magazins' layout below plug-in unit, take lymphocyte directly just can pour out, can not spill below plug-in unit.Its operation is simpler, and minimizing rifle head draws the impurity that time error causes, purer than common separation.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of novel separation of lymphocytes pipe, comprise body 1, described body 1 is tubular, and the bottom of tubular is centrum shape, is positioned at body 1 and is provided with a plug-in unit 2, described plug-in unit 2 is by a cylindrical structure 3 and a concave structure 4 is one-body molded forms, described concave structure 4 is positioned at the top of cylindrical structure 3, the bottom hollow out of cylindrical structure 3; Be positioned on described plug-in unit 2 and be also provided with several for separating of lymphocytic cavernous structure.
The center being positioned at described concave structure 4 is provided with a center sorting hole 5, the diameter of described center sorting hole 5 is 1.8mm ~ 2.3mm, the preferred 2mm of the present embodiment, as long as again can within the scope of this, lymphocyte separation medium is positioned at the below of plug-in unit 2, the pyramidal portion of body 1, plug-in unit 2 is blood above, blood is gone down by center sorting hole 5 in centrifugal process, meanwhile, lymphocyte separation medium is expressed to above plug-in unit 2 from the cavernous structure of plug-in unit 2, is so just easy to separation of lymphocytes to come.
The edge of described concave structure 4 also offers several U-type groove holes 6 uniformly, described U-type groove hole, the rounding diameter of 6 is 0.8mm ~ 1.2mm, preferred 1mm in the present embodiment, as long as certainly within the scope of this, can, and the opening in several U-type groove holes 6 all outwardly, the number in described U-type groove hole 6 is three, when when carrying out separation of lymphocytes, facilitates the blood sample on plug-in unit 2 and lymphocyte separation medium to carry out exchange of substance.
The bottom of described cylindrical structure 3 offers several arcuate sockets 7 uniformly, the arc degree of depth of described arcuate socket 7 is 1mm, width is 4mm, and the number of arcuate socket 7 is three, and the setting of arcuate socket 7 is used for the sample of centrifuge tube when centrifugal above parting liquid and plug-in unit 2 and exchanges.
The diameter 1mm larger than the diameter of cylindrical structure 3 of described concave structure 4, and the inwall of body is close at the edge of concave structure 4, like this, shifting phenomena would not be there is easily in plug-in unit 2 in body 1, by larger than the diameter of cylindrical structure 3 for the diameter design of concave structure 4 1mm, its effect also forms aperture between such U-type groove hole 6 and body 1, in centrifugal, lymphocyte separation medium can be split into above plug-in unit by these apertures.
The opening in described U-type groove hole 6 contacts with cylindrical structure 3, and forms a waist-shaped hole.
Be provided with several stiffening webs 8 in described plug-in unit 2, the setting of stiffening web 8 serves effect that is stable and that reinforce.
The beneficial effects of the utility model: lymphocyte separation medium is added below plug-in unit and then adds sample more than plug-in unit, can directly make the layering of target lymphocyte above plug-in unit through centrifugal, by magazins' layout below plug-in unit, take lymphocyte directly just can pour out just can, can not spill below plug-in unit.Its operation is simpler, and minimizing rifle head draws the impurity that time error causes, purer than common separation, is separated quicker, centrifugal 10 minutes; And without the need to closing whizzer brake.
Its centrifugal method is:
(1), when using, lymphocyte separation medium is joined below plug-in unit 2 by center sorting hole, the pyramidal portion of body 1;
(2) then, add blood sample from the edge of body 1, blood sample is positioned at the top of plug-in unit 2;
(3) then carry out centrifugal, centrifugal rear lymphocyte layering is above plug-in unit 2, and magazins' layout is below plug-in unit 2;
(4) when sampling by separator tube conversely, center sorting hole is just on the lofty perch of plug-in unit 2, and add that the liquid in the plug-in unit 2 of capillary effect the inside cannot be poured out, target substance is above poured out.So just can well by separation of lymphocytes out!
