Abstract
The utility model discloses a blood vessel used for clinical examination, comprising a syringe, a test tube, a tube stopper, a needle holder, an outer needle head and an inner needle head. The utility model is characterized in that the needle holder is arranged at the front end of the syringe; the outer needle head and the inner needle head are communicated with each other and arranged on the needle holder; a handle is arranged at the rear end of the syringe; one end of the test tube is closed, while the tube stopper is arranged on the open end; negative pressure is arranged in the test tube before use; the test tube can slide in the syringe; the test tube can be used as a blood container and a piston rod of ordinary injectors, therefore, blood collection and injection can be completed at a time, and pollution to blood sample caused by cross infection and operation process can be prevented. The utility model has the advantages of simple structure and convenient use.
Description
Technical field
This utility model belongs to a kind of medical apparatus, especially a kind of apparatus that is used to take a blood sample.
Background technology
At present, most of medical departments all adopt blood collection needle, and mostly this syringe is plastic injector glass or disposable, still must inject in advance in vitro off-the-shelf after the blood sampling.This blood sampling mode exists certain problem in operating process: the one, again blood is injected in vitro after having adopted blood, and cause cross-contamination easily; The 2nd, directly in the blood injecting tube, haemolysis takes place easily with syringe: the 3rd, medical personnel's troublesome poeration, give operation flexibly, speed, accurately bring certain difficulty; For addressing these problems, Chinese patent discloses a kind of " disposable use vacuum test tube ", this vacuum test tube is that the twice program of adopting, annotate with syringe " unites two into one ", though this hemostix does not have cross infection and pollution hidden trouble, but complex structure, operation inconvenience, inconvenience is promoted the use of in clinical.
Summary of the invention
The purpose of this utility model provides and a kind ofly will take a blood sample, annotates the blood taking tube that blood integrates, and has problem simple in structure, easy to use, as not have cross infection.
The purpose of this utility model is to realize like this, this blood taking tube comprises syringe, test tube, the test tube plug, needle stand, outer syringe needle, interior syringe needle, described syringe front end is a needle stand, the outer syringe needle that communicates is housed on the described needle stand, interior syringe needle, described back end of syringe is a handle, described test tube one end is sealing, opening is provided with a test tube plug, described is negative pressure before use in vitro, and described test tube can slide in syringe, is the position that guarantees that test tube slides in syringe, be provided with a locating snap ring at the syringe front end, when test tube advanced forward in syringe, when the test tube plug was run into locating snap ring, just in time interior syringe needle penetrated the test tube plug.
The beneficial effects of the utility model are: test tube is the Sheng blood vessel, has become the piston rod of ordinary syringe again, once finishes blood sampling, annotates two processes of blood, has prevented in cross infection and the operating process the pollution of blood sample, and is simultaneously, simple in structure, easy to use.

Cutaway view when Fig. 2 uses for this utility model
Among the figure: 1, syringe 2, test tube 3, test tube plug 4, needle stand 5, outer syringe needle 6, interior syringe needle 7, locating snap ring 8, handle
The specific embodiment
As Fig. 1, shown in Figure 2, this blood taking tube comprises syringe 1, test tube 2, test tube plug 3, needle stand 4, outer syringe needle 5, interior syringe needle 6, syringe 1 front end is a needle stand 4, the outer syringe needle 5 that communicates is housed on the needle stand 4, interior syringe needle 6, syringe 1 rear end is a handle 8, test tube 2 one ends are sealing, opening is provided with a test tube plug 3, be negative pressure before use in the test tube 2, test tube 2 can slide in syringe 1, is the position that guarantees that test tube 2 slides in syringe 1, be provided with a locating snap ring 7 at syringe 1 front end, when test tube 2 advanced forward in syringe 1, when test tube plug 3 was run into locating snap ring 7, just in time interior syringe needle 6 penetrated test tube plug 3.
During use, in the test tube 2 is negative pressure, and hand-held syringe 1 thrusts outer syringe needle 5 in the skin blood vessel, pinches handle 8 with finger then, promote test tube 2 with thumb, when test tube plug 3 was run into locating snap ring 7, at this moment, interior syringe needle 6 just in time penetrated test tube plug 3, in test tube 3 under the effect of negative pressure, blood promptly flows in vitro, treat that blood sampling finishes after, it is to be checked to extract test tube out.
Test tube is the Sheng blood vessel, has become the piston rod of ordinary syringe again, once finishes blood sampling, annotates two processes of blood, has prevented in cross infection and the operating process the pollution of blood sample, and is simultaneously, simple in structure, easy to use.
