The present invention relates to a synthetic resin airing cap for a syringe which is used by being combined with a disposable syringe used in medical field and, specifically, to a synthetic resin airing cap for a syringe which smooths injection and absorption of an injection by being combined with the syringe when injecting or absorbing the injection inside vial and flowing through external vial and air without generating sound pressure inside the vial. The synthetic resin airing cap for a syringe comprises: a pipe shaped housing which is formed with synthetic resin material, and in which the inside which makes body is penetrated, and front and back are opened; a hub fixing unit which is formed as the inside is penetrated in order for the hub of the syringe is inserted into the rear side of the housing in order to be closely fixed; a middle part which is extended to be connected to the hub fixing unit; a vial insertion unit which is formed to be inserted into the vial while being extended to be connected to the middle part; a syringe needle insertion path which is formed by being penetrated in order for the syringe needle to be closely inserted into the inside the vial insertion unit; a front ventilation tool which is formed in an opened hole form in order for the external housing and the internal housing to be connected in front part of the vial insertion unit; a ventilation path which is formed by being penetrated inside the vial insertion unit and is connected to the front ventilation tool; and a hole shaped rear ventilation tool which is formed for the external and internal housing to be connected by being connected to the ventilation path in the rear part of the housing. |
