Abstract: A needle cover for a needle on a syringe which can be removed through the application of a single finger force against a lever arm that is integral with the needle cover, where said force causes the needle cover to rotate laterally away from the needle sheathed within, wherein the continued application of finger force deflects the needle over from a coaxial position, therein exposing the sheathed needle, to a perpendicular position where the needle cover is well out of the way of subsequent activity, where said needle cover is comprised of a tapered tube of sufficient length and diameter to sheath the needle and the hub, and extending lengthwise is a longitudianl slit which expands to an elongated hole in a wall of the tapered tube, and opposite to the elongated hole is a partially open hole that opens toward the syringe, where these two holes create a space into which the hub can move when the tube is rotated, where the partial opening serves as a constriction which prevents the needle cover from rotating un

Abstract: A manually actuated, self-distending, self-inflating resuscitator bag that is substantially shaped like a pleated, handleless bellows where the pleats act like a spring following compression to rapidly re-inflate the bag to its fully recovered state, and that the flat sides of the bellows enable the operator to easily pump the bag with one hand or a knee as there is no tendency to roll away during the compression cycle.
