Abstract

An apparatus that transports radiopharmaceuticals and protects individuals from radioactivity that includes a first body with a first hollow core open on a first edge and a second edge. The first hollow core surrounds an insert containing a hypodermic syringe. There is a second body with a second hollow core open on a first edge and closed on a second edge. The second hollow core surrounds the insert with the hypodermic syringe. A third body with a third hollow core open on a first edge has the third hollow core fixedly communicating with a hollow stem open on a second edge. The third hollow core surrounds the insert with the hypodermic syringe. A first connection means releasably communicates the first body with the second body and a second communication means releasably communicates with the first body and third body for providing protection from the radioactive agent. A third connection means releasably communicates the third body with a dose applicator for injecting and measuring the radiopharmaceutical in the hypodermic syringe. Finally, the dose applicator is for positioning the insert and the hypodermic syringe into and out of the first and third body whereby said individuals easily measure, transport and inject the radiopharmaceutical in the hypodermic syringe.

Claims

1. An apparatus that acts as a shield for radiopharmaceuticals and protects individuals from radioactivity comprising:

a first body with a first hollow core that is open on a first edge and a second edge of said first body, said first hollow core for housing an insert;

a second body with a second hollow core that is open on a first edge and closed on a second edge of said second body, said second hollow core for housing said insert;

a third body with a third hollow core that is open on first edge of said third body, said third hollow core fixedly communicates with a hollow stem, said hollow stem is open on a second edge of said third body, said third hollow core for housing said insert;

said insert housing a hypodermic syringe with a radiopharmaceutical;

a first connection means wherein said first body releasably communicates with said second body for providing protection from said radioactivity;

a second connection means that said first body releasably communicates with said third body for providing protection from said radioactivity;

a third connection means for said third body to releasably communicate a dose applicator for injection and measuring said radiopharmaceutical in said hypodermic syringe; and

said dose applicator for slideably positioning said insert, hypodermic syringe and radiopharmaceutical into and out of said first and third body when said secondary is removed whereby said individuals easily measure, transport and inject said radiopharmaceutical in said hypodermic syringe.

2. The apparatus as claimed in claim 1 wherein each of said first body, second body and third body is constructed of material selected from the group consisting of lead, tungsten, lead acrylate, lead methacrylate, tungsten-polymer compounds and tungsten alloy.

3. The apparatus as claimed in claim 1 wherein said hypodermic syringe has a capacity of up to 50 cubic centimeters.

4. The apparatus as claimed in claim 1 wherein the shape of each of said first body, said second body and said third body is selected from the group consisting of cylinder, tapered cylinder and combinations thereof.

5. The apparatus as claimed in claim 1 wherein said connection means is selected from the group consisting of threaded connection, locking nut and compression flange.

6. The apparatus as claimed in claim 1 wherein said means for slideably positioning said hypodermic syringe further comprises an applicator rod, a rod connector, a threaded connection and locking nut with an o-ring to securely fasten said applicator rod to said disposable insert and said third body.

7. The apparatus as claimed in claim 1 wherein said insert mechanically secures around said hypodermic syringe.

8. The apparatus as claimed in claim 1 wherein said insert further comprises a first section and a second section wherein said second section is detachable from said first section.

9. The apparatus as claimed in claim 8 wherein each of said first and second section is constructed of material selected from the group consisting of polyethylene terephthalate, high density polyethylene, polyvinyl chloride, polypropylene, tungsten-polymer compounds and combinations thereof.

10. The apparatus as claimed in claim 1 wherein said second body is removable from said first body allowing said radiopharmaceutical in said hypodermic syringe to be measured in a well counter.

11. The apparatus as claimed in claim 1 wherein said means for slideably positioning said insert is removable from said third body and replaceable with a cap for protecting said individual from said radiation when transporting said radiopharnaceutical.

12. The apparatus as claimed in claim 1 wherein said second and third body are removable from said first body for said individual to manipulate said hypodermic needle to inject a patient with said radiopharmaceuticals and be protected from said radiation.
