Abstract
The utility model relates to a special blood-drawing injector whose piston body is a hollow body with a cavity, and the tail end of the piston body is a semi-sphere. When the utility model is used for blood drawing, after the blood sample is sucked into the injector, the injector is erected, the blood can be fully filled into the cavity in the piston body, and the piston can be used as a test tube. Because the piston body of the utility model can be used for replacing a test tube, the possibility of hemolysis and blood polluting can be reduced.
Description
This utility model relates to a treatment and uses syringe, a kind of specific purpose tool of gathering blood of definitely saying so.
At present each hospital's blood sample collection all is to use syringe to finish, and the blood sample of extraction reinjects in the test tube, and this method is easy to increase the probability of blood contamination because many one formality and vessel (test tube), perhaps destroys hemocyte, even causes appearance blood.
The purpose of this utility model provides a kind of specific purpose tool of blood sample collection, and it is melted into a whole hemostix and test tube, reduces the blood contamination rate.
The technical solution of the utility model is achieved in that the blood sampling syringe has the piston body 4 of a hollow, and the afterbody of piston body is a hemisphere, and promptly piston handle 6, and the two connecting place is a axis of the piston 5.
Using this utility model can directly take a blood sample the blood suction in the cavity of syringe piston body 4, then piston body 4 is extracted, directly put into test tube rack, thereby avoided the secondary injecting tube and scrubbed the pollution that test tube brings, guaranteed the reliability that blood sample collection is chemically examined.
This utility model concrete structure is provided by following embodiment and accompanying drawing ().
The special-purpose blood sampling of figure (one) disposable test tubular type syringe partly cut open figure.
Below in conjunction with accompanying drawing (one), describe details and working condition in detail according to the concrete device that the utility model proposes.
Comprise as figure (one) this utility model: syringe needle 1, nipple 2, empty tube 3, piston body 4, the axis of the piston 5, piston handle 6.
Syringe needle 1 is installed on the nipple 2, and nipple 2 is an one with empty tube 3, is ducted bodies at empty tube 3 intracavity piston bodies 4, and it is piston handle 6 that the afterbody of piston body 4 has a hemisphere, and the two connecting place is a axis of the piston 5.After during blood drawing the hemostix that installs being thrust blood vessel, be pulled outwardly piston body 4, blood promptly is drawn in the cavity of empty tube 3, and blood sampling finishes and piston body 4 is extracted, erects and extracted out to syringe its piston handle 6 is inserted in the test tube rack down.
Claims (2)
1, a kind of blood sampling syringe of medical blood sample collection, it is made up of syringe needle 1, nipple 2, empty tube 3, piston body 4, and it is characterized in that: the piston body is a ducted body.
2, according to the special-purpose blood sampling of the described disposable test tubular type of claim one syringe, it is characterized in that: the tail end of piston body 4 is that a hemisphere is a piston handle 6, is the axis of the piston 5 between the two.
