Abstract: A multi-function vacuum cleaner nozzle for attachment to the end of a vacuum cleaner hose. The device comprises a housing body (40), a dust brush (44), and two pivotal cleaning arms (6). Housing (40) has three ports (50), (52), and (54) extending therethrough, with port (50) and port (52) being adapted to receive a suction conduit (4). Port (52) is fitted with dust brush (44) which snaps into a recess (42) encircling said housing. Insertion of the conduit into port (52) selects the arms to receive suction air and substantially doses off port (50). Arms (6) are attached on the end of port (54) which is opposite port (52). Friction ridges (28) and (74) interact with each other, allowing several stable positions for arms (6). This makes the arms adjustable between upholstery, crevice, edge and corner tool positions. Insertion of said conduit into port (50) selects said dust brush to receive suction air and substantially closes off port (54).

Abstract: A device for protecting practitioners from inadvertent punctures with contaminated needles. The device comprises a safety shield (40), needle (51), handle (34), and a helical spring (35). Needle (40) and spring (35) are molded into handle (34) with needle tip (52) projecting forward. The opposite end of spring (35) is attached to shield (40) such that spring (35) is compressed when shield (40) is in a retracted position. Handle (34) comprises a receiving hub (28) with lock tabs (30) for securing the invention to a syringe, and a latching tube (37) with notches (38a and 38b) formed on the interior. The safety mechanism is activated by squeezing finger grips (36a) and (36b). This action increases the distance between notches (38a) and (38b), thereby releasing safety shield (40). Spring (35) is designed so that its natural length is slightly shorter than is necessary for center hole (48) to reach needle tip (52).
