Abstract
A safety structure for a needle of a syringe including an external bushing connected with a base, and a barrier structure on the base contacts with the needle, which has an extended bushing on a base frame. At the front end of the bushing there is an extended cannula with an outer edge through which a needle is inserted. The external bushing is made of soft materia. A trocar boring on a front end of the base is connected with the trocar-admitting part. Moving the barrier structure away from the needle and pushing the base back, the trocar boring of the base covers outside of the outer edge of the needle. The base is fixed on the needle by friction between a wall of the trocar boring and the outer edge of the cannula.
