    Abstract: A medical device has a base having an internally tapered wall mounted to a neck of a tube holder that has a reverse taper, so that rotation of the base relative to the neck may be effected with a controlled drag to provide a smooth and secure relative rotation. The base may be rotated relative to the holder by rotationally moving a needle protection housing hingedly attached to the base. The housing may be rotated to any orientation relative to the tube holder so long as a torsional force greater than the predetermined friction between the tapered surfaces is applied thereto. The base is designed to have a ring at its base that biases against the base of the neck in a self-adjustable manner. Other devices may also be fitted with reverse tapered complementary connection fittings to securely couple to each other.

    Abstract: This document discusses, among other things, an apparatus comprising a pump configured to deliver insulin, a processor, and a user interface including a bistable display. A display element of the bistable display is placed in one of two stable orientations upon application of a biasing voltage and stays in the stable orientation when the biasing voltage is removed. The processor includes a display module configured to display a non-blank reversion display screen on the bistable display when no input is received at the user interface after a specified time duration, and to recurrently change the reversion display screen until input is received at the user interface.
