First Claim
Patent Images
1. A radiopharmaceutical pig assembly for shielding a syringe containing radioactive material during transport and discharge of the syringe, the syringe having a flanged body with a needle and an opposing plunger extending therefrom, the radiopharmaceutical pig assembly comprising:
- a radiation-dense lower body portion having a threaded upper end, and an interior surface defining a first internal cavity with an opening in the upper end sized to accept the needle of the syringe therein;
a radiation-dense mid body portion having a upper end, a lower end and an interior surface extending therebetween to define a passageway between openings in the upper and lower ends of the mid body portion, the passage sized to accept the body of the syringe therein, the lower end of the mid body portion being threaded to releasably engage the threads on the lower body portion, the passage in the mid body portion located in alignment with the cavity in the lower body portion upon their engagement;
a locknut threadedly engaging the upper end of the mid body portion; and
a radiation-dense upper body portion having a lower end and an interior surface defining a second internal cavity with an opening in the lower end of the upper body portion, the opening and cavity being sized to accept the plunger of the syringe therein, the lower end being threaded to releasably engage the locknut such that the passageway in the mid body portion is located in alignment with the cavity in the upper body portion.

11. A method of transporting and discharging a syringe containing radioactive material utilizing a dual purpose radiopharmaceutical pig having removable upper and lower body portions, the syringe having a body with a needle and an opposing plunger extending from the body, the method comprising:
-
receiving the radiopharmaceutical pig holding the syringe containing the radioactive material; removing the upper and lower body portions of the radiopharmaceutical pig to expose the needle and the plunger of the syringe and retain a portion of the radiopharmaceutical pig to shield the body of the syringe; positioning the remaining portion of the radiopharmaceutical pig containing the syringe such that the needle of the syringe is in a predetermined location for discharge; and pushing the plunger of the syringe downward to force radioactive material out of the syringe. - View Dependent Claims (12)
