<p><P>PROBLEM TO BE SOLVED: To provide a novel cartridge type syringe in which content liquid can be sucked from an outside while making it possible to filling and substituting the content liquid and air can be efficiently removed during injection. <P>SOLUTION: The cartridge type syringe has a cartridge having a syringe and a piston member, a mount tool 20 for mounting the cartridge, and a plunger 30 capable of pushing the piston through the mount. The rear end part of the piston and the distal end part of the plunger are formed in a fitting shape capable of attaching and detaching each other. A sleeve 40 is rotatably held between the distal end side convex part 36 arranged in the plunger 30 and the rear end side to convex part 37, the sleeve 40 is retractably housed in the mount 20 along with the plunger 30, a rear end side convex part 37 contacts the sleeve rear end 40b so as to be able to push the sleeve 40, and an elastic member 50 which provides restoring force to the push in of the sleeve 40 is arranged between the sleeve 40 and the mount 20. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
