Abstract: A cannulator (100) can include a compound needle (104) and a compound cannula (102). The compound needle can include a needle (110), a dilator (108), and a needle hub (106). The dilator can be disposed over the needle with at least a tip of the needle extending beyond a distal end of the dilator. The needle hub can be around a proximal-end portion of the dilator. The compound cannula can include a cannula (140) and a cannula hub (142) around a proximal- end portion of the cannula. The cannulator can have a mated state of the compound needle and the compound cannula for at least cannulation with the cannulator. The mated state of the cannulator can include the dilator disposed in the cannula with a proximal-end portion of the cannula hub coupled to a distal-end portion of the needle hub.

Abstract: A light-emitting beaded necklace for ornamental decoration having a plurality of ornamental beads that each define opposed slots for receiving the beads on an elongate thread. At least one light source is enclosed within one of the beads. The elongate thread extends through the opposed slots of the beads in sequence and distal ends connect together to define a looped article of wearing apparel. The necklace has pendent with a circuit for generating an electrical signal for illuminating the light source to provide a lighted ornamental effect for the beaded necklace. A method of assembling a light-emitting beaded necklace is disclosed.
