Abstract:
1. A storage arrangement for an oxygen sensitive device including provision for indicating the presence of oxygen within the storage arrangement comprising: a. a sealable container that isolates contents of the sealable container from ambient atmosphere when sealed; b. an oxygen sensitive device located within the sealable container, the oxygen sensitive device having the form of a product or apparatus such that the oxygen sensitive device is configured for use in a procedure other than the sensing of oxygen, for example as a medical device useful in a medical procedure; and, c. an oxygen sensor having an oxygen-sensitive material of a polycarbonate mixture, the polycarbonate mixture designed for color stability when exposed to radiation, located within the sealable container separate from the oxygen device, the oxygen-sensitive material being inactive prior to exposure to radiation and activatible by exposure to radiation, the activation of the oxygen-sensitive material causing the oxygen-sensitive material to become sensitive to oxygen exposure only after activation and to remain sensitive to oxygen exposure after completion of radiation exposure and to undergo a visual change in response to subsequent contact with oxygen, the oxygen sensor having a configuration such that the only utility of the oxygen sensor is as a sensor, the oxygen sensor being located within the sealable container separate from the oxygen sensitive device such that the oxygen sensor is not part of said oxygen sensitive device nor any other device that may be included within said sealable container.
