An injection needle 8 is attached to the end part 10 of the base 2. The injection needle 8 may be integrated with the distal end 12 of the base 2 by molding, or may be attached to the distal end 12 after a safety device is removed from a molding. A base end part 14 of the base 2 is designed to have a cavity. The cavity is engaged with a syringe or other liquid storage devices. A lure connector 16 is formed in the base 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
