The present invention is a filter syringe.Especially...A equipment is upgraded from a syringe, which is equipped with a filter device for filtering foreign substances such as glass bottle fragments.Therefore, the opening or closing of one-way valve medium is controlled according to whether the plug is separated or not.Moreover, the design of the filter medium can also make it larger in the transverse region, so that the liquid drug can be absorbed lightly with less intensity. The filter syringe includes a No. 10 syringe consisting of a No. 11 syringe and a No. 12 syringe.There is also a No. 20 cylinder No. 10 butt joint.Best of allThe 12th cube of injector 10 consists of 12D annular space with 12A area of inner wall.Surface of exterior wall 12B and surface below 12CThe lower 12C surface is composed of 12E passage port connected with No. 20 cylinder.A one-way 300 valve medium made of elastic material is provided on the inner wall surface of 12A by its cylindrical part 360 and part 370.The corner of 370 wing has elastic contact with the surface of 12B exterior wall.A filter medium 200 is installed between the one-way 300 valve and the 12E aisle in the 12D annular range.The filter needle also includes a 100 plug consisting of a hollow body with a sharp point inside and sealed with the outer surface of cube 12.There are 400 opening/closing media around needle No. 11 in plug No. 100. The filter syringe is configured to allow liquid drugs to be filtered and inhaled through a filter medium in its area.Maximum cross section, even if the minimum force is automatically closed in the assembled plug state and unidirectional valve medium for injection of liquid drugs in a separate plug stateThis will maximize the convenience and TradeAbility of syringe users.La presente invención se refiere a una jeringa con filtro, y más particularmente, a un aparato obtenido mejorando una jeringa provista de un medio filtrante para filtrar sustancias extrañas tales como fragmentos de vidrio de
