Abstract
A full viewing shielding holder for radionuclid disposable plastic syringes is disclosed. Maximum light gathering for illumination of the syringe scale and clear visibility of that scale in any relatively rotated position of the holder and of the syringe therein are afforded by the improved holder comprising a tubular body of radiation shielding glass translucent and optically polished substantially throughout its circumference and length and having a quickly engageable and disengageable syringe gripping means fitted on one end thereof. In one disclosed embodiment the releasable gripping means comprises a rubber 'O'-ring compressible against the syringe body by a clamping means to hold the syringe in place by friction. In a second embodiment the releasable gripping means comprises an internally threaded fitting cooperating with an element on the syringe. When the syringe is inserted into the holder, a slightly tapered annular flange on the end of the syringe enters the fitting snugly, whereupon turning of the syringe with insertion pressure continued causes self-threading of the fitting in the soft flange material to hold the syringe releasably.
