Claims

[Scope of Claim for Utility Model Registration] (1) A container containing a medical radiochemical solution is held in an inverted state by the container holding means, and a syringe with a needle facing upward is raised from below the container to remove the needle. A syringe gripping device for a radiopharmaceutical liquid dispensing device for dispensing a required amount of medical solution by inserting the syringe into the opening of the container, the syringe gripping device having a pair of syringe clamping members each holding the top and bottom of a syringe equipped with a shield. Each pair of clamping members has portions facing each other formed in a substantially dogleg shape to clamp the syringe, and is provided with a mechanism that expands and contracts the distance between them in accordance with syringes of different diameters, and the expansion and contraction mechanism In this case, racks fixed to each pair of clamping members are arranged above and below, and the upper and lower racks engage gears arranged between them from both sides and can move in opposite directions. A syringe gripping device for a radiopharmaceutical liquid dispensing device, comprising bearings on the upper and lower sides for guiding movement, and a spring biasing the clamping members in a direction that reduces the gap between them. (2) The syringe gripping device according to claim (1),
A detecting means is provided which detects the grasping of the syringe and identifies the size of the syringe by inserting a shielded syringe into the grasping device and pushing the tip of the detection rod with the syringe, and the detection means is configured to move the detection rod to which it is fixed. a spring member, one end of which contacts the movable member and the other end of which pushes the actuator of the first microswitch, and a second microswitch with which the movable member pushes the actuator. When a small-diameter syringe is gripped, a small movement of the movable member activates the first microswitch via the spring member, and when a large-diameter syringe is gripped, a large movement of the movable member activates the first microswitch. A syringe gripping device for a radiopharmaceutical liquid dispensing device, characterized in that a first microswitch is operated via a spring member, and a second microswitch is operated via the moving member.
