Patent ID: 7537560

Claim:
A shielded radioactive medical apparatus for use in medical treatments requiring radioactive objects, the apparatus comprising: a single tubular housing including a closed end and an open end, a plurality of bores located proximate the open end, a plurality of pins located within the plurality of bores, and a plurality of springs engaged with the plurality of pins for outwardly biasing the plurality of pins; a quick release cap having a distal end and a proximate end, the proximate end configured for closing the open end of the tubular housing wherein the proximate end includes a receiver, and a quick release mechanism configured for engaging and holding the quick release cap on the open end of the tubular housing and quickly releasing the quick release cap when actuated by a user, the quick release mechanism including a collar movably engaged along the open end of the tubular housing, the collar including a first end and a second end, wherein the first end includes an inclined engagement surface; a biasing member engaged with the collar to bias the collar in a direction substantially away from the closed end of the tubular housing; wherein the quick release cap may be rapidly engaged with the tubular housing by inserting the proximate end of the cap within the collar so that the plurality of pins are urged inward in the plurality of bores as the pins slide along the inclined engagement surface of the first end of the collar and the plurality of pins engage with the receiver, thereby substantially locking the quick release cap onto the tubular housing; and wherein the quick release cap may be rapidly removed from the tubular housing by moving the collar toward the closed end of the tubular housing so that the plurality of pins are no longer urged into the plurality of bores and engaged with the receiver, thereby substantially freeing the quick release cap from the tubular housing.
