By adopting technique scheme, the all size disposable needle or single use venoclysis needle that blood device matches is store with blood sampling, carrying out in the process of drawing blood, core bar draws toward the tube port position of syringe, after making the annular groove of the catch ring on pin head and syringe tube port position stuck, core bar just can not back be promoted, and ensure that the blood in syringe can not be extruded outside syringe.
This utility model is set to further: described core bar is provided with the kink facilitating core bar to fracture, and kink is the opening of molding on core bar.
By adopting technique scheme, after the annular groove of the catch ring on pin head and syringe tube port position is stuck, core bar can not slide in syringe again, fracture core bar, use pin head to serve as bottom syringe, be directly used as test tube and use, also centrifugal blood on centrifuge.
This utility model is set to further: on described pin head also cover have the packed-piston cover inconsistent with syringe inwall, packed-piston cover outer wall be provided with cannelure, described cannelure both sides are configured with two annular protrusions, annular protrusion and syringe inwall inconsistent.
The packed-piston cover inconsistent with syringe inwall is had by pin head also overlaps, by packed-piston cover is set to quality of rubber materials, can avoid occurring because different the expanding with heat and contract with cold of southern and northern temperature difference causes sealing poor, the heat-resisting cold resistance of rubber can be utilized, ensure that sealing, and be provided with cannelure by packed-piston cover outer wall, described cannelure both sides form two annular protrusions and syringe inwall inconsistent, when extruding, annular protrusion can crimp, thus overallly improve sealing.
This utility model is set to further: be provided with the sealing ring be parallel to each other with cap inwall in described cap.
By being provided with the sealing ring be parallel to each other with cap inner body wall in cap body, when cap body is threaded with syringe time, the syringe of blood taking syringe can be placed between sealing ring and cap inner body wall, by carrying out crush seal to syringe between cap inner body wall and sealing ring, add and be threaded, make sealing effectiveness more.
This utility model is set to further: described sealing ring outer wall is provided with protuberance.
By adopting technique scheme, utilize sealing ring outer wall to be provided with protuberance, by when connection, the syringe inwall of blood taking syringe can be inconsistent with the protuberance of projection, and make when fixing, sealing effectiveness is better.
This utility model is set to further: be provided with the annular groove be placed between sealing ring and cap inwall in described cap body.
By adopting technique scheme, the annular groove be placed between sealing ring and cap inwall is provided with in cap, by the design of annular groove, when rotation, the termination of the syringe of blood taking syringe can be embedded in annular groove, making the syringe termination of blood taking syringe can be inconsistent with the bottom land of annular groove, by rotating sealing of conflicting, sealing effectiveness being further enhanced.

Detailed description of the invention
With reference to Fig. 1-Fig. 2, embodiment of the present utility model is described further.
A kind of disposable blood sampling storage blood device, comprise syringe 1, stretch into the core bar 2 be slidably connected with syringe 1 in syringe 1 and the pin head 3 be placed in syringe 1, the threaded one end of syringe 1 is connected with cap 10, described core bar 2 is one-body molded with pin head 3, pin head 3 is provided with catch ring 31, and the tube port position of syringe 1 offers the annular groove 30 with catch ring 31 adaptation.
The all size disposable needle or single use venoclysis needle that blood device matches is store with blood sampling, carrying out in the process of drawing blood, core bar 2 draws toward the tube port position of syringe 1, after making the catch ring 31 on pin head and the annular groove 30 of syringe 1 tube port position stuck, core bar 2 just can not back be promoted, and ensure that the blood in syringe 1 can not be extruded outside syringe 1.
Core bar 2 is provided with the kink 2a facilitating core bar 2 to fracture, and kink 2a is the opening of molding on core bar 2.
After the catch ring 31 on pin head 3 and the annular groove 30 of syringe tube port position are stuck, core bar 3 can not slide in syringe 1 again, and fracture core bar 2, uses pin head 3 to serve as bottom syringe 1, is directly used as test tube and uses, also centrifugal blood on centrifuge.
