<p>The present invention relates to a filter assembly for a syringe which is combined with a needle unit of the syringe comprising: a conical hat or a slab shaped elastic boom in which edge can be shrunk down by pressure for absorbing medicine; a circular filter which is arranged with distance from the lower side of the boom and filters foreign materials in the medicine absorbed when the edge of the boom is shrunk; and a discharging column which has a penetration hole in the middle and discharges the medicine filtered using the filter by connecting a head unit of the boom to a center unit of the filter. The present invention: filters foreign materials such as fragments of glass and rubber pieces by including the filter assembly for syringe in the syringe unit, thereby discharging medicine without foreign materials from the syringe; and makes the medicine go through the filter when being absorbed into the syringe, thereby being able to directly inject the medicine into a patient who can be directly injected and injecting the medicine through a valve installed in an IV hose after removing a syringe needle from a patient with the IV.</p> |
