Abstract

A radio-pharmaceutical pig for transporting a syringe containing a radio-pharmaceutical includes a first cylindrical member having a first tungsten body defining a first cavity therein A second cylindrical member has a second tungsten body defining a second cavity therethrough and is capable of engagement with the first cylindrical member so that the first cavity is in substantial alignment with the second cavity. A third cylindrical member includes a third tungsten body defining a third cavity and is capable of engagement with the second cylindrical member so that the third cavity is in substantial alignment with the second cavity. The first cavity, the second cavity and the third cavity are shaped so as to be complimentary in shape of the syringe.

Claims

1. A radio-pharmaceutical pig, for transporting a syringe containing a radio-pharmaceutical, comprising:

a. a first cylindrical member, including a first tungsten body defining a first cavity therein opening to a first end;

b. a second cylindrical member, including a second tungsten body defining a second cavity therethrough, including a proximal end and an opposite distal end, the proximal end capable of engagement with the first end of the first cylindrical member so that the first cavity is in substantial alignment with the second cavity, an anti-roll structure extending outwardly from a portion of the second cylindrical member, the second cylindrical member also including an external stainless steel sleeve covering a portion of the second cylindrical member with a gripping surface cut into the second external stainless steel sleeve;

c. a third cylindrical member, including a third tungsten body defining a third cavity opening to a primary end, the primary end capable of engagement with the distal end of the second cylindrical member so that the third cavity is in substantial alignment with the second cavity,

wherein the first cavity, the second cavity and the third cavity are shaped so as to be complimentary in shape of the syringe.

2. The radio-pharmaceutical transport system of claim 1, wherein the second cylinder member may be disengaged from the first cylinder member and the third cylinder member and wherein the second cylinder member has dimensions that allow the second cylinder member to be used to shield the syringe while the syringe is being used to deliver the radio-pharmaceutical to a receptacle.

3. The radio-pharmaceutical transport system of claim 1, wherein the gripping surface comprises a diamond patterned scoring.

4. The radio-pharmaceutical transport system of claim 1, wherein the first anti-roll member and the second anti-roll member each comprise a block that extends outwardly from the tungsten cylinder, the block having at least three substantially flat sides.

5. The radio-pharmaceutical transport system of claim 4, wherein the block has four substantially flat sides.

6. A radio-pharmaceutical pig, for transporting a syringe containing a radio-pharmaceutical, comprising:

a. a first cylindrical member, including a first tungsten body defining a first cavity therein opening to a first end, a first anti-roll structure extending outwardly from a portion of the first cylindrical member, the first cylindrical member also including a first external stainless steel sleeve covering a portion of the first cylindrical member with a gripping surface cut into the first external stainless steel sleeve;

b. a second cylindrical member, including a second tungsten body defining a second cavity therethrough, including a proximal end and an opposite distal end, the proximal end capable of engagement with the first end of the first cylindrical member so that the first cavity is in substantial alignment with the second cavity, a second anti-roll structure extending outwardly from a portion of the second cylindrical member, the second cylindrical member also including a second external stainless steel sleeve covering a portion of the second cylindrical member with a gripping surface cut into the second external stainless steel sleeve;

c. a third cylindrical member, including a third tungsten body defining a third cavity opening to a primary end, the primary end capable of engagement with the distal end of the second cylindrical member so that the third cavity is in substantial alignment with the second cavity, a third anti-roll structure extending outwardly from a portion of the third cylindrical member, the third cylindrical member also including a third external stainless steel sleeve covering a portion of the third cylindrical member with a gripping surface cut into the third external stainless steel sleeve,

wherein the first cavity, the second cavity and the third cavity are shaped so as to be complimentary in shape of the syringe.

7. The radio-pharmaceutical transport system of claim 6, wherein the second cylinder member may be disengaged from the first cylinder member and the third cylinder member and wherein the second cylinder member has dimensions that allow the second cylinder member to be used to shield the syringe while the syringe is being used to deliver the radio-pharmaceutical to a receptacle.

8. The radio-pharmaceutical transport system of claim 6, wherein the gripping surface comprises a diamond patterned scoring.

9. The radio-pharmaceutical transport system of claim 6, wherein the first anti-roll member and the second anti-roll member each comprise a block that extends outwardly from the tungsten cylinder, the block having at least three substantially flat sides.

10. The radio-pharmaceutical transport system of claim 6, wherein the block has four substantially flat sides.

11. A method for using a three section pig, including a first member, a second member and a third member, into which a radio-pharmaceutical filled syringe, having a needle extending therefrom, has been placed, comprising the steps of:

a. disengaging the second member from the first member and the third member;

b. gripping the second member, with the syringe disposed therein so that the needle extends from one end of the second member, and

c. injecting at least a portion of the radio-pharmaceutical into a receptacle.
