MEDIZINISCHES, INSBESONDERE ZAHNMEDIZINISCHES BEHANDLUNGSINSTRUMENT ZUR ABGABE EINES ABRASIVEN STRÖMUNGSMEDIUMS

摘要

The invention relates to a medical, in particular dental-medical treatment instrument which is adapted for delivery of an abrasive flow medium. The treatment instrument includes a handpiece, an arranged on the handpiece reservoir (1) for an abrasive treatment medium, a feed line (2) for compressed air, which opens into the reservoir (1) and from the reservoir (1) to an outlet opening for the abrasive flow medium extending derivative (4). In this case, (2) air deflection means (6) in an end portion of the supply line are arranged which are adapted to substantially dispense regardless of the orientation of the handpiece, the compressed air in a lower region of the reservoir (1) in these. In this way can cause the air pressure is in the course of treatment particularly long in close or virtually direct contact with the treatment agent and thus the treatment agent is particularly effective long swirled. As a result can be achieved that can be achieved with the treatment instrument removal rate remains constant over a long period of time within narrow limits.
