It is connected to syringe needle 25.
In the present embodiment, blood back situation when injection is observed by setting injection pipeline 24, is injected to patient
When radio nuclide examination, radionuclide is injected into patient's vein, before injection, it is quiet that syringe needle 25 is penetrated into patient
Arteries and veins, judges whether syringe needle 25 penetrates patient's vein by having seen whether blood back, and syringe needle 25 has penetrated trouble if blood back
Person's vein can be injected at this time, cannot inject if without blood back, and existing syringe is difficult to observe whether there is blood back,
Need to twitch piston 14 backward just it can be observed that blood back situation, uses very inconvenient, novel syringe and infuse to patient
When penetrating radionuclide, if syringe needle 25 penetrates patient's vein, venous blood can flow back into injection pipeline 24, and injection pipeline 24 is in
Blood red can inject at this time, if injection pipeline 24 does not have blood red, cannot inject, novel syringe uses
It is more convenient.
In the present embodiment, by setting groove 26 and flange 27 come so that between connection male connector 21 and connection female 22
Connection it is stronger, when will connection male connector 21 be fixedly attached in connection female 22 when, groove 26 and flange 27 are mutually fitted
To match, the groove 26 and flange 27 of arc make the contact area for connecting male connector 21 and connecting between female 22 bigger, so that
The connection for connecting male connector 21 and connecting between female 22 is stronger, for comparing more existing syringe, novel syringe
