<P>PROBLEM TO BE SOLVED: To provide a passive safety system relating to an injector pen needle for protecting a patient and/or a medical expert using a pen needle from unexpected puncture, retracting the pen needle into a device for safety. <P>SOLUTION: A retracting safety injector pen needle has the needle mounted on a carrier which is movable with respect to the hub, so that the non-patient end of an injection pen needle device is retracted into a hub after an injection for safety. When an injection is given, the needle is retracted into the needle part, so that the non-injection end of the needle is automatically shielded, so it is passive. <P>COPYRIGHT: (C)2009,JPO&INPIT |
