| 摘要 |
The present invention is a device for capturing abrasive particles expelled from air-abrasive apparatus and permitting their facile removal without the aid of a vacuum source, while facilitating an unobstructed view of the working area during use. One embodiment disclosed is a capture and removal device ( 1 ) of abrasive material ( 70 ) expelled by a gas abrasive dental apparatus ( 25 ) by generating a water curtain ( 50 ) from a water steam ( 45 ) delivered substantially tangential to concave surface ( 20 ) of a curved sheet ( 10 ). A method is disclosed for using water curtain ( 50 ) generated by capture and removal device ( 1 ) to capture and remove abrasive material ( 70 ) from the vicinity of an air-abrasive procedure. Certain other embodiments of the device can be used for non-dental applications.
