Abstract

An apparatus for filling a medical instrument with a radioactive substance, said apparatus including a housing designed to receive a syringe and at least part of a medical instrument and to shield against radioactive radiation, further including a means to take up a receptacle for a radioactive substance.

Claims

1-17. -17. (canceled)

18. An apparatus for filling a medical instrument with a radioactive substance, comprising:

a housing, wherein the housing is adapted to receive a syringe and at least a part of a medical instrument and shield against radioactive radiation;

a shielding device, wherein the shielding device is adapted to shield an end of an injection plunger projecting from the syringe; and

a means to take up a receptacle for a radioactive substance arranged at the housing, wherein the housing comprises;

a lid, wherein the lid covers or closes the apparatus and the receptacle for a radioactive substance arranged at the housing; and

a first opening, wherein the first opening allows actuation of the injection plunger of the syringe arranged in the apparatus.

19. The apparatus as claimed in claim 18, wherein the means to take up the receptacle is adapted for the receptacle to be arranged and fastened outside of the housing, wherein the housing further comprises a second opening, wherein the second opening allows a connection to be made to the receptacle for a radioactive substance into the housing.

20. The apparatus as claimed in claim 18, wherein the housing further comprises a means for manipulating a valve disposed inside the housing, wherein the means for manipulating the valve is actuatable from outside the housing.

21. The apparatus as claimed in claim 18, wherein the housing is made of a material that shields radioactive radiation.

22. The apparatus as claimed in claim 18, wherein the housing is made of tungsten.

23. The apparatus as claimed in claim 18, wherein the housing comprises a window.

24. The apparatus as claimed in claim 18, wherein the housing comprises a flap, wherein the flap is adapted to close the window.

25. The apparatus as claimed in claim 18, wherein the housing is adapted for securing the syringe and the at least a part of the medical instrument, wherein the housing is adapted for receiving and securing one or more valves and connecting lines.

26. The apparatus as claimed in claim 18, wherein the housing comprises a third opening, wherein the third opening allows passage of the medical instrument.

27. The apparatus as claimed in claim 18, further comprising:

a support, wherein the support is connected to the housing in such a way that the apparatus and the syringe arranged inside the housing are inclined with respect to a base surface.

28. The apparatus as claimed in claim 18, wherein the medical instrument is a catheter.

29. A system for filling a medical instrument with a radioactive substance, comprising:

an apparatus, wherein the apparatus comprises;

a housing, wherein the housing is adapted to receive a syringe and at least a part of a medical instrument and shield against radioactive radiation;

a shielding device, wherein the shielding device is adapted to shield an end of an injection plunger projecting from the syringe; and

a means to take up a receptacle for a radioactive substance arranged at the housing, wherein the housing comprises;

a lid, wherein the lid covers or closes the apparatus and the receptacle for a radioactive substance arranged at the housing; and

a first opening, wherein the first opening allows actuation of the injection plunger of the syringe arranged in the apparatus;

a receptacle for a radioactive substance; and

a syringe.

30. The system as claimed in claim 29, further comprising:

a valve disposed in the apparatus;

the medical instrument arranged at least partly in the apparatus; and

hose sections for connecting the syringe, the valve, the receptacle for a radioactive substance, and the medical instrument.

31. The system as claimed in claim 29, wherein the receptacle for a radioactive substance is removably attachable to the apparatus.

32. A method for filling a medical instrument with a radioactive substance, comprising:

introducing a syringe into an apparatus, wherein the apparatus comprises;

a housing, wherein the housing is adapted to receive a syringe and at least a part of a medical instrument and shield against radioactive radiation;

a shielding device, wherein the shielding device is adapted to shield an end of an injection plunger projecting from the syringe; and

a means to take up a receptacle for a radioactive substance arranged at the housing, wherein the housing comprises;

a lid, wherein the lid covers or closes the apparatus and the receptacle for a radioactive substance arranged at the housing; and

a first opening, wherein the first opening allows actuation of the injection plunger of the syringe arranged in the apparatus; and

drawing the radioactive substance into the syringe while using the shielding device to shield the end of the injection plunger.

33. The method as claimed in claim 32, further comprising:

arranging at least a part of the medical instrument in the apparatus; and

filling the medical instrument with the radioactive substance from the syringe.

34. The method as claimed in claim 32, further comprising:

returning the radioactive substance from the medical instrument into the syringe.

35. The method as claimed in claim 32, further comprising:

returning the radioactive substance from the medical instrument into the receptacle.
