Holder and tool for radioisotope elution system
View Patent ↗A holder for a vial containing a sterile liquid for use with a radiopharmaceutical elution system includes a holder body. The body has a top, an opposing bottom, an opening in the top and a vial chamber. The vial chamber extends from the opening in the top toward the bottom and is sized and shaped for receiving the vial therein. An access opening extends through the bottom to the vial chamber and is aligned with a septum of the elution vial when the sterile vial is received in the vial chamber. A cap is removably secured to the top of the holder body for selectively opening and closing the vial chamber. The holder body includes plastic and has a density less than the density of the cap.
1. A radiation shield for an eluant vial in combination with a radiation shielding lid for use with a radiopharmaceutical elution system, the radiation shield comprising:
a shield body having a closed top, an open bottom, and defining a cavity extending from the bottom toward the top, wherein the cavity is designed to accommodate at least a bottom portion of an eluant vial; and
a pair of shielding wings extending downward from the bottom and partially surrounding the cavity,
wherein the shield body and the shielding wings comprise at least one of depleted uranium, tungsten, and tungsten impregnated plastic;
the radiation shielding lid comprising a body having an upper surface and an opposing lower surface; a first opening defined in the body, the first opening having a lower end at the lower surface of the body and an upper end intermediate the upper and lower surfaces of the body; a pair of finger recesses defined in the body, the recesses having an upper end and a lower end, wherein at least portions of the upper ends of the recesses are located at the upper surface of the body, and wherein at least portions of the lower ends of the recesses are located at the upper end of the first opening; and first and second wings, each of which extends upward from the upper end of the first opening and only partially about a circumference of the upper end of the first opening such that gaps are defined between the first wing and the second wing.
2. The radiation shield set forth in claim 1 , wherein the body comprises at least one of depleted uranium, tungsten, tungsten impregnated plastic, and lead.
3. The radiation shield set forth in claim 1 , wherein the shielding wings of the radiation shield are receivable in the finger recesses such that the shielding wings are in opposing relationship with the gaps defined between the first and second wings of the lid and the top of the shield body covers the first and second wings.
4. The radiation shield set forth in claim 1 , wherein the finger recesses of the radiation shielding lid have a generally ellipsoidal shape, and wherein each shielding wing of the radiation shield includes an exterior surface having a curved portion sized and shaped to engage the finger recesses of the radiation shielding lid.
5. The radiation shield set forth in claim 4 , wherein each shielding wing further includes a flat bottom surface, wherein the bottom surface is substantially parallel to the bottom of the shield body.
6. The radiation shield set forth in claim 1 , wherein the finger recesses are diametrically opposed to one another with respect to the first opening, and wherein the shielding wings are diametrically opposed to one another about the cavity in the shield body.
7. The radiation shield set forth in claim 1 wherein the radiation shielding lid further comprises a second opening defined in the body, the second opening having a lower end at the lower surface of the body and an upper end at the upper surface of the body, the second opening being spaced apart and separate from the first opening.
8. The radiation shield set forth in claim 1 , wherein the shield body and the shielding wings further comprise at least one of polypropylene and polycarbonate.
9. The radiation shield set forth in claim 1 , further comprising a radiation shielding core comprising at least one of depleted uranium, tungsten, tungsten impregnated plastic, and lead, wherein the shielding body and shielding wings are at least partially constructed from an overmolded thermoplastic material.
10. The radiation shield set forth in claim 1 , wherein the cavity has a generally cylindrical shape, and the shielding wings extend circumferentially about the cavity.
11. A radiation shield for an eluant vial in combination with a radiation shielding lid for use with a radiopharmaceutical elution system, the radiation shield comprising:
a shield body having a closed top, an open bottom, and defining a cavity extending from the bottom toward the top, wherein the cavity is designed to accommodate at least a bottom portion of an eluant vial; and
a pair of shielding wings extending downward from the bottom and partially surrounding the cavity,
wherein the shield body and the shielding wings comprise at least one of depleted uranium, tungsten, and tungsten impregnated plastic;
the radiation shielding lid comprising a body having an upper surface and an opposing lower surface, wherein the body comprises at least one of depleted uranium, tungsten, tungsten impregnated plastic, and lead; a first opening defined in the body, the first opening having a lower end at the lower surface of the body and an upper end intermediate the upper and lower surfaces of the body; and a recess defined in the body, the recess having an upper end and a lower end, wherein at least a portion of the upper end of the recess is located at the upper surface of the body, and wherein at least a portion of the lower end of the recess is located at the upper end of the first opening; and first and second wings, each of which extends upward from the upper end of the first opening and only partially about a circumference of the upper end of the first opening such that gaps are defined between the first wing and the second wing.
12. The radiation shield set forth in claim 11 , wherein the body comprises at least one of depleted uranium, tungsten, tungsten impregnated plastic, and lead.
13. The radiation shield set forth in claim 11 , wherein the radiation shielding lid further comprises a second opening defined in the body, the second opening having a lower end at the lower surface of the body and an upper end at the upper surface of the body, the second opening being spaced apart and separate from the first opening.
