Title: DROPPER SYRINGE APPARATUS
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.
