ANAESTHETIC PREPARATION FOR LOCAL ANAESTHESIA

摘要

PROBLEM TO BE SOLVED: To improve handling quality and working efficiency by integrating plural pieces of pin material bodies by connectors in the state parallel and disposing these connectors at two points near the base ends of receiving parts and near the base ends of insertion parts. ;SOLUTION: The pin material bodies 1 are integrally provided with the receiving parts 3 at their one-side ends. The receiving parts 3 are provided with insertion holes 5 having an approximately rectangular shape and a pair of detaining parts 6 are formed within these insertion holes 5. Constricted parts 8 are formed at the based ends of the insertion parts 7 formed at the other-side ends of the pin material bodies 1. These constricted parts 8 engage with the detaining parts 6 after the insertion parts 7 pass between the detaining parts 6. The first connectors 11 are disposed along stepped parts constituting parts 9. The connectors 11 and the stepped parts constituting parts 9 are integrally connected by cuttable joint members 12. The second connectors 13 are disposed in the state parallel with the first connectors 11 on the rear surface near the top ends of the receiving parts 3.;COPYRIGHT: (C)1998,JPO
