摘要： An evacuation hand piece for collecting debris during dental procedures. The hand piece is adapted for attachment to evacuation apparatus and provides both intra- and extra-oral suction. A body member of the hand piece has a contoured outer gripping surface which makes the hand piece easier to grasp. A mask is disposed at one end of the hand piece to create a suction area which is larger than the cross sectional area of the body member. The mask is attached to a spherical tip of the body member to form a ball and socket-type connection which permits directional adjustment of the mask, thereby maximizing the effective extra-oral suction of the hand piece. The mask is formed from transparent material to allow viewing through the mask during dental procedures.
摘要翻译：用于在牙科手术期间收集碎屑的疏散手部件。手持件适于附接到排气装置，并提供口内和口外抽吸。手柄的身体部件具有轮廓的外部抓握表面，其使手柄更容易掌握。掩模设置在手持件的一端，以产生大于主体部件的横截面积的吸引区域。面罩附着在本体构件的球形末端上以形成允许方向调节面罩的球窝式连接，从而最大限度地提高了手持件的有效的口外抽吸力。掩模由透明材料形成，以允许在牙科手术期间通过掩模观察。

摘要： A system for treating teeth and associated tooth structure using a pressurized air propellant mixed with abrasive material includes a manifold which defines air passages leading from the pressurized air source to dispensing chambers which hold the abrasive material. The manifold further provides a convenient structure for mounting a number of the system components. The manifold simplifies assembly of the system and improves the integrity of air passages within the system. The air abrasion system also has a mixing block and continuous purge feature which eliminate crosstalk and backflow problems when switching between abrasive materials. Evacuation apparatus incorporating a cyclone separator is integrally provided with the system which requires minimal regular maintenance and maximizes suction flow through the apparatus. A boost feature of the system is provided to selectively increase the ratio of abrasive material to air in an air-abrasive material mixture, thereby increasing the rate of tooth reduction, without requiring additional air pressure.
摘要翻译：使用与研磨材料混合的加压空气推进剂来治疗牙齿和相关牙齿结构的系统包括限定从加压空气源引导到保持研磨材料的分配室的空气通道的歧管。歧管还提供了用于安装多个系统部件的方便的结构。歧管简化了系统的组装并提高了系统内空气通道的完整性。空气磨损系统还具有混合块和连续吹扫功能，可在磨料之间切换时消除串扰和回流问题。包括旋风分离器的疏散装置与系统一体地提供，其需要最少的定期维护并且使通过设备的吸入流最大化。提供了系统的增强特征，以选择性地增加研磨材料与空气研磨材料混合物中的空气的比例，从而增加齿减速率，而不需要额外的空气压力。
