Devices in which components of medical kits are carried are identifiable by means other than by the naked eye. The means for identification is attached to or integral with the device and may comprise raised and lowered surfaces that can be read by touch serrations disposed on an edge or surface a fluorescent coating viewable under infrared or ultraviolet light or a pattern that is viewable using a thermal imaging device such as night vision goggles. A package for retaining a medical item includes an identifying element of a material that is selectively viewable in response to light attributes of the material. A device for the visual identification of a package containing a medical item includes an identifying element comprising a material that is visually discernible in reduced-light environments via the use of night vision devices.
