Dispensing and injection system for radiopharmaceuticals
First Claim
1. A radiation-shielded dispensing and injection system for radiopharmaceuticals, comprising:
- a radiation-shielded hermetic chamber, forming a closed, radiation-shielded interior space, the radiation-shielded hermetic chamber also forming at least one injection needle insertion hole;
a vial containing radiopharmaceuticals therein;
at least one saline water cartridge arranged inside the hermetic chamber at an injection position adjacent to the injection needle insertion hole, the saline water cartridge forming an internal passage, a radiopharmaceuticals discharge, and a radiopharmaceuticals injection end;
at least one disposable syringe; and
a movable dispensing and injection mechanism for controlling radiopharmaceuticals dispensing operation of the syringe, and controlling movement of the syringe between a radiopharmaceuticals dispensing position and the injection position;
wherein when the movable dispensing and injection mechanism moves the syringe to the radiopharmaceuticals dispensing position, the syringe withdraws a predetermined amount of radiopharmaceuticals from the vial and when moved to the injection position, the syringe injects the withdrawn radiopharmaceuticals into the radiopharmaceuticals injection end of the saline water cartridge.

Abstract
Disclosed is a dispensing and injection system for radiopharmaceuticals, wherein a dosage calibrator is arranged inside a radiation-shielded hermetic chamber for detecting the radioactivity of radiopharmaceuticals contained in a vial. At least one saline water cartridge is arranged inside the casing and includes an internal passage, radiopharmaceuticals discharge end, a radiopharmaceuticals injection end, a and saline water reservoir outlet end. The saline water cartridge forms a saline water reservoir. A movable dispensing and injection mechanism controls radiopharmaceuticals dispensing operation of a syringe and controls movement of the syringe between a radiopharmaceuticals dispensing position and an injection position. When the movable dispensing and injection mechanism moves the syringe to the radiopharmaceuticals dispensing position, the syringe withdraws a predetermined amount of radiopharmaceuticals from the vial. When moved to the injection position, the syringe injects the withdrawn radiopharmaceuticals into the radiopharmaceuticals injection end of the saline water cartridge. After the radiopharmaceuticals is injected into a patient, the saline water stored in the saline water reservoir of the saline water cartridge is withdrawn for effecting flushing process.
