Needle Cap Ejector for Radiation Shielded Syringe
First Claim
1. A radiation shielding assembly comprising:
- a syringe comprising;
a barrel for containing a radioactive substance; and
a needle located at one end of the barrel;
a radiation shielding body having a cavity defined therein for receiving at least a portion of the barrel of the syringe, the body having at least one opening into the cavity defined therein for delivery of a radiopharmaceutical in the barrel of the syringe exterior of the cavity through the opening; and
a needle cap ejector supported by the radiation shielding body, the needle cap ejector being operable to detach the needle cap from the syringe upon manual application of a detachment force to the needle cap ejector.

Abstract
The invention relates to a radiation shielded syringe assembly that includes a radiopharmaceutical syringe and a radiation shield (101) disposed about at least a portion of the syringe. The radiation shield may include a needle cap ejector (155) to assist a user in removing a needle cap (125) from a needle of the syringe (e.g., to perform an injection). For instance, in some embodiments, the user may press/push the needle cap ejector to detach the needle cap from the needle of the syringe. The radiation shield and needle cap ejector may be designed such that the needle cap may be removed from the needle of the syringe while the user is shielded from undesired exposure to radiation emitted from the radiopharmaceutical within the syringe.
