Background technology
Nuclear Medicine Dept's nephro-dynamic imaging inspection is relied on to internal injection radiopharmaceutical and provides developing function.Existing behaviour
As program it is：The first step：Set up venous channel.It is that patient injects physiology salt with the syringe connection scalp acupuncture equipped with physiological saline
Water；Second step：Injection of radioactive substances.After puncturing success, change syringe and radiopharmaceutical fast injection will be penetrated in vivo；The
Three steps：Bullet rushes residual drug in syringe.Syringe injecting normal saline is changed immediately, for guaranteeing radiopharmaceutical most short most
Reach in the patient in the fast time, need Quick-pressing to inject, reach bullet and rush effect.
There are four drawbacks in above operation sequence：One easily causes pollution when being and changing repeatedly syringe；Two is that pressurization is pushed away
Note is easily caused syringe and is disengaged with syringe needle junction；Three is that complex operation easily causes medicine decay；Four is that plastic injection quality is operated
Person's proficiency and stability affect larger.

The course of work：
In two inclined tubes 2 of closing of slide switch valve 3, of right side, 6 action of second piston in the second cavity 7, pass through
Flexible pipe syringe needle 9 sucks radiopharmaceutical；5 action of first piston of the first cavity 4, sucks physiological saline by syringe needle 1, enters the
In one cavity 4.During injection, first piston 5 is first promoted, physiological saline is squeezed into an Ink vessel transfusing part, then adjust slide switch
Valve 3, cuts out the first cavity 4；Rapid radiopharmaceutical is squeezed into the pressurization of second piston 6, then adjust slide switch valve 3, close the
Two cavitys 7, promote first piston 5, saline injection again.
Advantage of the present utility model：
Radiopharmaceutical injection device described in the utility model, theory structure are simple, easy to operate, effectively prevent anti-
The problem polluted when changing syringe again；Operation does not result in rapidly medicine decay, is easy to be precisely controlled, and notes beneficial to improving
