  • Patent number: 11219718
    Abstract: The present invention improves the feeling in use when a finger is hooked on a finger grip. This syringe is provided with a cylinder 22, a syringe needle 24, a finger grip 30, and a plunger rod 32. The finger grip 30 is provided with a cylindrical portion and a pair of finger hook portions. The finger hook portion has an inclined curved surface 70 and an end-side curved surface 72. The inclined curved surface 70 is disposed on a side, of a side surface of the finger hook portion, connected to the cylinder 22. In the inclined curved surface 70, the inclination of a base-side region with respect to the center axis of the cylindrical portion is gentler than the inclination of an end-side region with respect to the center axis of the cylindrical portion. The end-side curved surface 72 is disposed at the boundary between the end of the finger hook portion and the inclined curved surface 70. The end-side curved surface 72 extends along the boundary.

  • Patent number: 10357618
    Abstract: A injection-needle cover includes an injection needle enclosure portion, which has paired base-side wall portions, a cylinder portion, paired tip-end-side wall portions, an injection needle contact portion, a hook portion, and a needle tip end fixing portion. The injection needle contact portion is disposed at a position in a base-side axial space, which is a boundary between the base-side axial space and an intra-cylinder space. The injection needle contact portion has a force receiving portion and a connecting portion. The force receiving portion receives a force from the injection needle when the force receiving portion comes in contact with the injection needle. The force receiving portion has an easy sliding portion, which is disposed in an area adjacent to an injection needle, and slides more easily along the injection needle than a case where an edge slides along the injection needle.
