Abstract

Safety syringe, comprising a chamber configuration tubular barrel, a plunger mounted within the camera faculty of sliding along the same, and a fitting holder needle fixable to the chamber, which chamber is open at one of its bases, through overhanging the plunger and flows by aopuesta through a nozzle under section to which connects the fitting holder needle through a tubular coupling that is plugged externally on the nozzle and embraces said fitting ; whose piston is finished, outward in a driving head and the stayed at the camera end on a driving head adjustable on the inner surface of the chamber, ahead of which extends in an element connectible to fitting needle; characterized in that on the piston, behind head impulsora, at least one weakened section breakage or deformation; while the camera has interiorly in its wall near the base open, locking means of the drive piston head in its position of maximum extraction, in which section or sections deformation or breakage are located outside the camera, to cause deformation or breakage of piston to try again introduction into the chamber; and because the piston element to the fitting connectable needle cap consists of a prong recessed topped on a peripheral nerve external fitting said to act as traccionadores elements thereof; whose acople tubular available media internally and pressing for guiding claws cap fitting cited against holders needle during penetration through the nozzle, preventing its removal of said needle holder.
