PROBLEM TO BE SOLVED: To guarantee the firm frictional fixing of an injection member to an injection holder before using. SOLUTION: An injector includes a hollow barrel part 12 with opposed open tip parts and a manually operable plunger within one tip of the part 12. An injection holder 26 is fixed to the other tip of the barrel part 12. Injection members such as a percutaneous injection needle assembly 28 and an intraveneous access device are fixed detachably to the holder 26. A cover 24 houses the injection members and can be housed detachably to the holder 26. The cover 24 can be moved concerning the holder 26 from a first position of holding the cover in the injection holder to a second position of detaching the cover from the holder. The moving of the cover 24 from the first position to the second position guarantees the detachable fixing of an injection member 27 to the injection holder 26 of the injection member 27. |
