Abstract

The invention discloses a nuclear medicine injection device which comprises a syringe, an injection head, an injection needle, a puncture head, a plug, a piston, a push rod, a positioning cylinder, a positioning ring and a vent valve. An injection head is formed at the front end of the injection cylinder, can be communicated with an injection needle and can also be plugged by a plug, and the injection head is detachably connected with the plug; the side wall of the syringe is communicated with a positioning cylinder, a positioning ring is installed in the positioning cylinder, the outer end face of the positioning ring is connected with the nuclear medicine storage bottle, the outer end face of the positioning ring is sunken to form an insertion hole, the normal saline storage bottle is inserted into the insertion hole, and a puncture head is fixed to the inner hole wall of the positioning ring and used for puncturing tin foil paper on the nuclear medicine storage bottle and tin foil paper on the normal saline storage bottle; a movable piston is mounted in an inner hole of the syringe, and the piston is fixed to a push rod extending to the outside; and an exhaust hole is formed in the positioning cylinder and is opened and closed by a vent valve. The nuclear medicine injection device solves the problem that in the prior art, nuclear medicine is prone to polluting a needle head in the exhaust process.

Description
