    • Provided is an easy-to-handle prefilled type nasal drip appliance which can spray medical solution surely into the nostril while holding down the production cost. A syringe barrel has a spray hole and a latching portion of a center stopper on one side, with a conduction portion of medical solution being provided at the latching portion, and has a portion protruding inward of the inner circumferential surface formed on the other end side. A plunger has a portion protruding outward of the outer circumferential surface formed substantially in the axial center wherein both protrusions engage with each other. When the plunger is moved in the spray direction of the syringe barrel to get over the plunger side protrusion and disengaged, the medical solution moves the center stopper in the spray direction to form a medical solution inflow groove between the conduction portion formed at the center stopper latching portion and the center stopper. Consequently, a medical solution storage portion and the spray hole are interconnected and the medical solution can be sprayed.
    • 提供了一种易于处理的预充型鼻滴式器具,可以将药液固定在鼻孔内,同时降低生产成本。 注射器筒在一侧具有喷孔和中心止动器的闩锁部分,药液的导电部分设置在闩锁部分处,并且具有从形成在另一端侧的内周面向内突出的部分 。 柱塞具有大致在轴向中心形成的外周面向外突出的部分,其中两个突起彼此接合。 当柱塞在注射器筒的喷射方向上移动以越过柱塞侧突起并脱开时,医用溶液沿着喷射方向移动中心止动件,以在形成在中心塞的传导部分之间形成药液流入槽 闩锁部分和中心止动器。 因此,药液存储部和喷孔相互连接,能够喷射医用溶液。
