Dentists routinely inject local anesthetic solutions in their daily practice. However, it is important not to inject intravascularly. Consequently, manufacturers offer two types of dental syringes: one with a mechanical aspirating device (harpoon) and the other with a self-aspirating mechanism. We have verified the efficacy of a self-aspirating syringe as presented on the market and another self-aspirating syringe which we lightly modified.
牙医在日常工作中经常注射局部麻醉剂溶液。然而,避免血管内注射很重要。因此,制造商提供两种类型的牙科注射器:一种带有机械抽吸装置(牙钩),另一种带有自动抽吸机制。我们已经验证了市场上现有的一种自动抽吸注射器以及我们稍加改进后的另一种自动抽吸注射器的效果。
