Abstract

A HYPODERMIC SYRINGE COMPRISES A BARREL (10) HAVING AT LEAST ONE CATCHING PIECE (13) DISPOSED AT THE END; AN OUTER SLEEVE (20) FITTED ROTATABLY WITH THE BARREL TO TURN TO LOCATE AT THE FIRST POSITION (271) AND THE SECOND POSITION (272) AND PROVIDED AT LEAST ESCAPE HOLE (26); A NEEDLE HOLDER (30) HAVING A CYLINDER COOPERATING PORTION (11) DISPOSED SLIDABLY IN THE RECEIVING HOLE (12) OF THE BARREL (10), A RETAINING CIRCULAR GROOVE (37) DISPOSED IN THE OUTER PERIPHERY OF THE NEEDLE HOLDER (30) FOR RETAINING THE CATCHING PIECE OF THE BARREL; A PLUNGER (40) HAVING A ROD BODY (41) CAPABLE OF PULLING BACK THE NEEDLE HOLDER (30). AS THE OUTER SLEEVE (20) IS TURNED TO THE FIRST POSITION, EACH CATCHING PIECE (13) OF THE BARREL RETAINS THE RETAINING TOOTH (131) OF THE BARREL. THE NEEDLE HOLDER (30) IS UNABLE TO DISPLACE. AS THE OUTER SLEEVE (20) IS TURNED TO THE SECOND POSITION, THE ESCAPE HOLE (26) IS CORRESPONDING TO THE CATCHING PIECE (13) OF THE BARREL TO EJECT OUTWARD. THE NEEDLE HOLDER (30) IS NOT CONFINED SO AS TO BE PULLED BACK BY THE PLUNGER (40). (FIG. 1)
