A new design of dental cartridge syringe which incorporates a double self-aspirating mechanism has been investigated under controlled conditions in the laboratory. The new design was compared to two self-aspirating syringes which have been available for some time, namely the Astra and Aspiject syringes. The new syringe aspirated as effectively as the Astra design and was better in this respect than the Aspiject. The method used to examine the syringes involved tests which might be of value in creating standards for dental local anesthetic cartridges.
一种采用双自动回吸机制的新型牙科卡筒式注射器已在实验室的可控条件下进行了研究。将这种新设计与两种已上市一段时间的自动回吸式注射器进行了比较，即阿斯特拉（Astra）注射器和阿斯皮杰克（Aspiject）注射器。新型注射器的回吸效果与阿斯特拉设计的注射器相当，在这方面比阿斯皮杰克注射器更好。用于检测注射器的方法所涉及的测试可能对制定牙科局部麻醉药卡筒的标准具有价值。
