1. A saline water cartridge for radiopharmaceuticals injection, comprising:

  • a casing defining an interior space forming saline water reservoir in which a predetermined amount of saline water is contained, the casing forming an inlet port and an outlet port sealed by needle penetrateable members, the inlet port adapted to receive a needle of a radiopharmaceuticals-carrying syringe that penetrates through the penetrateable member of the inlet port, the outlet port adapted to receive a needle of a patient injection device that penetrates through the penetrateable member of the outlet port, the reservoir forming an outlet;

    primary and secondary passages arranged inside the casing, the primary passage extending from the reservoir outlet, through which the saline water is replenished into the primary passage, to the inlet port of the casing, which allows injection of the radiopharmaceuticals contained in the syringe into the primary passage, the primary passage forming an opening communicating the secondary passage that connects to the outlet port of the casing;

    a first one-way membrane vale arranged in the opening of the primary passage to allow the saline water inside the primary passage with which the radiopharmaceuticals injected into the primary passage is mixed to flow into the secondary passage while preventing reverse flow of the mixture of the saline water and the radiopharmaceuticals;

    a second one-way membrane valve arranged in the outlet of the saline water reservoir to allow the saline water to flow from the reservoir into the primary passage, while preventing reverse flow of the saline water;

    wherein the radiopharmaceuticals contained in the syringe, after being injected into the primary passage through the inlet port of the casing, is prevented from flowing into the saline water reservoir by the second membrane valve and is only allowed to flow to the outlet port through the first membrane valve.
