Abstract: A shieldable swab assembly comprising an elongated shaft, a collector tip, and a slidable cover assembly. The slidable cover assembly may comprise a hollow cover and a plurality of strings extending through a central duct of the elongated shaft. The elongated shaft may pass through proximal and distal apertures of the hollow cover. The hollow cover may be capable of moving along a longitudinal axis of the elongated shaft. Each respective string of the plurality of strings may comprise a distal end that may extend outwardly from a distal opening of the elongated shaft and may be attached to an outer surface of a distal end of the hollow cover. The each respective string of the plurality of strings may further comprise a proximal end that may extend outwardly from a proximal opening of the elongated shaft. Proximal ends of the plurality of strings may be tied to one another.

Abstract: A dropper syringe apparatus includes a cylindrical barrel, a plunger assembly, and a needle. The cylindrical barrel storing the fluid includes a flanged first opening and a second opening. The plunger assembly, inserted into the cylindrical barrel, includes a plunger shaft and a flexible hollow bulb. The plunger shaft includes a flanged upper end, a lower end, and a central lumen. The plunger shaft moves in an upward and a downward direction within the cylindrical barrel. The central lumen extends from the lower to the flanged upper end of the plunger shaft for accommodating the fluid. The flexible hollow bulb is fixedly attached to the flanged upper end and in fluid communication with the central lumen. An external force exerted on the flexible hollow bulb exerts a pressure on the fluid accommodated within the lumen. The needle draws or dispenses the fluid from or to the external body.
