Section: claims

1. In a device for protection of gonads in x-ray diagnosis comprising a retaining frame for fastening to the collimator of an x-ray diagnosis instrument by means of insert strips, said retaining frame having means for receiving a movable support strip of material that is permeable to x-rays and which supports a member of material that is impermeable to x-rays, the improvement comprising said retaining frame being provided with a plurality of insert strips for fastening said retaining frame to said collimator, said insert strips being disposed on the retaining frame so as to be movable with respect to each other so that the protective device can be fastened to different x-ray diagnosis instruments, wherein said plurality of insert strips includes a pair of parallel insert strips,  wherein said pair of parallel insert strips are disposed on the retaining frame along a pair of parallel slots, said pair of insert strips being movable with respect to each other along said slots,  wherein portions of said pair of parallel insert strips adjacent said retaining frame are provided with prismatic guide tips which engage in said slots, and  wherein set screws are provided for securing said pair of parallel insert strips to said retaining frame, the shanks of said set screws projecting through said slots and engaging in threads provided in said pair of parallel insert strips. 2. The device for protection of gonads according to claim 1, wherein the means for receiving a movable support strip in said retaining frame includes two opposed retaining slots for receiving the movable strip and wherein two parallel retaining bridge members are provided on the retaining frame between said slots so that the support strip can be selectively inserted crosswise. 3. The device for protection of gonads according to claim 1, wherein said member is a plate having a configuration adapted to the female or male gonads to be protected. 4. A device for protection of gonads in x-ray diagnosis comprising a retaining frame for fastening to the collimator of an x-ray diagnosis instrument by means of insert strips, said retaining frame having means for receiving a movable support strip of material that is permeable to x-rays and which supports a member of material that is impermeable to x-rays, a plurality of insert strips for fastening said retaining frame to said collimator and means disposing said insert strips on said frame so that the relative position of said insert strips with respect to each other can be adjusted whereby the protective device can be fastened to different x-ray diagnosis instruments. 5. The device according to claim 4, wherein said plurality of insert strips includes a pair of parallel insert strips and said retaining frame includes a pair of parallel slots, said pair of insert strips being adjustably positioned with respect to each other along said slots by said means disposing the insert strips on the frame. 6. The device according to claim 5, wherein portions of said pair of parallel insert strips adjacent said retaining frame are provided with prismatric guide tips which engage in said slots. 7. The device according to claim 4, wherein the means for receiving a movable support strip in said retaining frame includes two opposed retaining slots for receiving the movable strip and wherein two parallel retaining bridge members are provided on the retaining frame between said slots so that the support strip can be selectively inserted crosswise.
