    • A dental syringe (10) has a needle (11) affixed to a carpule holder (12), which carpule holder (12) is affixed to a power drive unit (13). A harpoon (20) is provided to affix the drive unit to the carpule plunger (32). The harpoon (20) is made of stainless steel or other hard, corrosion resistant, sterilizable, material. Harpoon 20 has a unique barb geometry and hardened, knife-like, edges (21). The syringe (10) may operate to divide the delivery of anesthesia into two phases. According to the method, during the first about 10 seconds of the injection, anesthetic is delivered at an extremely slow rate to maximize patient comfort. The injection rate then automatically increases to the preprogrammed rate associated with the injection type selected.
    • 牙科注射器(10)具有固定在卡片保持器(12)上的针(11),该卡子保持器(12)固定到动力驱动单元(13)。 提供了一个鱼叉(20)以将驱动单元固定在卡头柱塞(32)上。 鱼叉(20)由不锈钢或其他硬质,耐腐蚀,可消毒的材料制成。 鱼叉20具有独特的倒钩几何形状和硬化的刀状边缘(21)。 注射器(10)可以操作以将麻醉的输送分成两个阶段。 根据该方法,在注射的第一个约10秒期间,以非常慢的速度递送麻醉剂以最大化患者舒适度。 然后,注射速率自动增加到与所选择的注射类型相关联的预编程速率。
