This utility model is set to further: the outfan of described syringe is provided with the catch ring for limiting connecting cylinder activity.
By adopting technique scheme, when core bar pull-out, when making piston slide to the tube port position of the outfan of syringe, connecting cylinder can be limited in catch ring, prevents piston movable, conveniently revolves core bar and disassemble from connecting cylinder.
This utility model is set to further: on described core bar, one end that is relative and piston head is provided with force dish, and the bottom surface of force dish is provided with some anti-skidding projections.
By adopting technique scheme, the beneficial effects of the utility model:
1. be connected with piston thread by one end of core bar, to make core bar can rotate core bar after having taken out blood, core bar rotated and takes out, make piston serve as bottom syringe, be directly used as test tube and use, also centrifugal blood on centrifuge.Before drawing blood, core bar draws toward the tube port position of syringe, piston is made to be stuck in bottom syringe, rotate core bar, make to produce vacuum in syringe, also become disposal vacuum blood taking tube and use, other operational approach is identical with vacuum test tube, do not affect by weather environment, atmospheric pressure, height above sea level like this, thus ensure that blood test mass effect.
2., by annular protrusion and the syringe contact internal walls of piston cylinder, greatly reduce the contact area of piston and syringe inwall, decrease frictional force, facilitate core bar push-and-pull in syringe.
3., by the input of butyl rubber bung sealing syringe, substantially increase the sealing of syringe, achieve the effect of vacuum hemospasia.
