Abstract: An assembly mountable to an injector, such as an injection pen, to hide the needle of the injector from view. The assembly includes a retractable cover that is slidably mounted on a base sleeve that is releaseably connected to the injector. A spring between the cover and the base sleeve biases the cover toward a forward position at which it surrounds and hides the axially fixed needle from view.

Abstract: A device for reading the labeled contents of an insulin container and then providing an audible message informing the user of the labeled contents. The device includes a recessed surface, such as a cylindrical well, into which an insulin container is insertable by a vision impaired person. An optical scanner or reader reads a code furnished as part of the labeling on the inserted insulin container. A microcomputer compares the read code to known code patterns and a speech output is generated as to the type of insulin within the container. The speech output is broadcast over a speaker so as to be audible to a listener. The device may be integrated into a blood glucose sensor, or furnished in a unit that may assemble to an existing blood glucose sensor.
