The equipment for local anesthesia is described in this article. Practical recommendations for the selection of the injection needle length, size, bevel type is given. Using dental needle for local anesthesia should be guided by the "one injection - one needle" rule, as a needle tends to deform by even the slightest contact with jawbone. Some of the shortcomings of carpule quality may be detected before use: signs of cup corrosion, the presence of sediment, air bubbles, rubber plunger disposition. In the case of such defects being identified all the package should not be used. The use of such carpule in clinical practice is unsafe.
本文介绍了局部麻醉设备。给出了选择注射针长度、尺寸、斜面类型的实用建议。使用牙科针进行局部麻醉应遵循“一针一用”原则，因为针哪怕与颌骨有最轻微的接触也容易变形。在使用前可检测到卡氏瓶质量的一些缺点：卡瓶腐蚀迹象、沉淀物、气泡、橡胶柱塞位置。如果发现此类缺陷，则不应使用整包产品。在临床实践中使用这种卡氏瓶是不安全的。
