Abstract

The present disclosure relates to a device (1) for sampling and/or injection of a radioactive solution (S) in a vial (2), wherein the vial (2) comprises an opening closed by a puncturable closure member (3).

The device (1) comprises a container (7) adapted to receive said vial (2) and a vial adaptor (4), said vial adaptor (4) having a longitudinal axis (L1), provided at a first end (41) with a hollow spike (42) adapted to pierce said puncturable closure member (3) when the vial adaptor (4) is mounted on the vial (2), and at a second end (43) with connection means (5) adapted for its removable connection to a syringe (6),
the container (7) comprising:

• • a container body (71) adapted to receive said vial (2), the container body (71) having an opening (711), and
  • a vial adaptor support structure (72) configured for being mounted onto the opening (711) of the container body (71), and comprising retention means configured for enabling releasable retention of said vial adaptor (4) within said vial adaptor support structure (72), and
  • wherein the vial adaptor support structure (72) and the container body (71) are made at least partially of a radioprotective material for providing protection against ionizing radiation.

Claims

1. A device useful for sampling and/or injection of a radioactive solution in a vial, wherein the vial has an opening closed by a puncturable closure member, the device comprising:

a container adapted to receive said vial and a vial adaptor, said vial adaptor having a longitudinal axis, provided at a first end with a hollow spike adapted to pierce said puncturable closure member when the vial adaptor is mounted on the vial and at a second end with connection means adapted for its removable connection to a syringe adaptor,

the container comprising;

a container body adapted to receive said vial, the container body having an opening, and

a vial adaptor support structure configured for being mounted onto the opening of the container body, and comprising retention means configured for enabling releasable retention of said vial adaptor within said vial adaptor support structure,

wherein the vial adaptor support structure and the container body are made at least partially of a radioprotective material for providing protection against ionizing radiation;

wherein the vial adaptor support structure further comprises transfer means for imparting to said vial adaptor a degree of freedom in longitudinal translation along its longitudinal axis;

wherein the vial adaptor support structure is generally tubular with a longitudinal axis and comprises;

a tubular sleeve having a first end provided with attachment means configured for enabling mounting of the vial adaptor support structure onto the opening of the container body,

a support ring, received in said tubular sleeve, coaxial with the tubular sleeve, and defining an internal space for the reception of said vial adaptor,

wherein the transfer means are further configured for imparting to said support ring a degree of freedom in longitudinal translation along said longitudinal axis with respect to said tubular sleeve, and

the retention means are further configured for enabling connection of said vial adaptor with said support ring.

2. The device according to claim 1, characterized in that the vial adaptor support structure comprises a jacket for operating said support ring according to said degree of freedom in translation, said jacket at least partially surrounding said tubular sleeve and including fastening means configured to fasten said jacket with said support ring.

3. The device according to claim 2, characterized in that said fastening means are in the form of at least two assembly lugs connecting said jacket and said support ring and which pass through oblong holes in said tubular sleeve.

4. The device according to claim 3, characterized in that said retention means comprise a radial bearing pin secured with said jacket and/or said support ring, wherein said bearing pin has an outer end accessible on an outer periphery of said jacket, provided with an operating member, and an inner end forming a bearing head, and wherein said bearing pin is movable radially between:

an active position in which said bearing head extends into said internal space of said support ring and is adapted to abut against said vial adaptor in order to assemble said vial adaptor with said support ring and/or said jacket, and

an inactive position in which said bearing head does not abut against said vial adaptor.

5. The device according to claim 4, characterized in that said bearing pin is also one of said assembly lugs.

6. The device according to claim 1, characterized in that the device further includes indexing means to at least one position, of the assembly comprising the vial adaptor, the support ring and the jacket, relative to said tubular sleeve.

7. The device according to claim 6, characterized in that said indexing means comprise at least one retractable ball lock mounted on one of the tubular sleeve or the jacket cooperating with a recess provided on the other of the tubular sleeve or the jacket.

8. The device according to claim 1, characterized in that said support ring comprises first positioning means configured for blocking said vial adaptor in a direction along its longitudinal axis, and second positioning means adapted to prevent rotation of said vial adaptor about said longitudinal axis.

9. The device according to claim 1, further comprising:

a syringe comprising a syringe body, a piston and a syringe adaptor configured for connection to said vial adaptor, and

a protection device shaped as a shield made of radioprotective material providing protection against ionizing radiation, wherein said protection device covers at least partially said syringe body and said syringe adaptor.
