Improved extractor syringe, characterized in that it is constituted by a tubular body or sleeve in whose interior of its extreme end in beak it has established or incorporated a unidirectional valve structure that only allows for the extractor action of the syringe for which the consequent displacement of the plunger in such a case sense causes the release of the lower inlet mouth of the liquid withdrawn by direct action of the liquid itself on a closure element to plug or close said mouth by the fall of the closure element in conjunction with the pressure of the liquid already extracted and lodged inside that body or shirt.
