摘要

Assembly for the practice of clinical testing, comprising a plunger stopper elastic hollow, provided with a closed by a pierceable septum bore and slidable in a container as a test tube containing the liquid under analysis, by the action a coupled to said plunger stopper to effect the transfer of liquid from the container to the tubular member tubular element simultaneously acting as a plug and as plunger, wherein the plunger stopper has a configuration as a sleeve provided with peripheral annular ribs which defines a cylindrical housing bore and incorporates an intermediate pierceable septum; that the coupling end of the tubular element to the plunger stopper has a configuration corresponding to that of the drill housing that at the free end of the tubular element a tubular cap provided with a partition wall defining an end fitting for coupling engages the free end delelemento tubular and a reservoir for containment of excess fluid filling the tubular member forming said partition a conical seat in which a ball allows passage of liquid from the tubular member to the reservoir to carry the mark of said element bears, and makes automatic closure which container is closed with a perforated cap in that the container has at its bottom a complementary conical projection stopper piston for maximum use of the amount of liquid in question, and that is completed by a support plate- slightly elastic material provided with a plurality of ta Ladros where respective containers are nestable by its bottom, being held to elastic pressure and held in position allowing a multiple determination of the VSG, previously subjecting the plurality of containers to the conventional stirring in the support itself, manually or mechanically.
