のＡ−Ａ部から見た正面図である。 Conventional dental needle bases have been made to fit either lock-fixed or screw-fixed syringe barrels. The present invention provides a dental injection needle that can be used with a single needle base for lock-fixed type or screw-fixed type syringe barrels. Next, the present invention will be explained in detail with reference to the drawings of one embodiment. FIG. 1 is a side sectional view of a conventional embodiment. Figure A shows a case where the needle base 2a of the injection needle 2 is connected to the lock portion 1a of the syringe barrel 1.
Figure B shows the needle base 4 of the syringe needle 4 attached to the threaded part 3a of the syringe barrel 3.
This is the case where a is screwed together. 5 is a cartridge containing an injection solution. The former has a convex part 2b on the needle base 2a of the injection needle 2 so as to fit into the lock part 1a of the syringe barrel 1, and the latter has a convex part 2b on the needle base 2a of the injection needle 4 so as to fit into the lock part 3a of the syringe barrel 3. A threaded portion 4b is provided on the needle base 4a. FIG. 2 is a side sectional view of one embodiment of the present invention. An injection needle 7 is connected to a needle base 6, and the needle base 6 is provided with a convex portion 6a on its outer circumferential surface that is compatible with a locking system, and a vertically elongated convex rib 6b on its inner surface. In use, the needle base 6 fits into the syringe barrel 1 of the locking type shown in FIG. 6b. Especially the vertically long convex rib 6b
is screwed in and fixed by the threaded portion 3a of the syringe barrel 3 while being tapped. FIG. 3 is a front view taken from section AA in FIG. 2.
