摘要:
A method and corresponding system for operating a dental handpiece, wherein the handpiece comprises a motor for driving a tool. the method comprises (a) sequentially capturing values of a physical parameter, which—at least approximately—represent the power or energy fed to the motor, (b) forming an integration value by integrating the values captured in (a), and (c) automatically reducing a power or energy fed to the motor if the integration value formed in (b) exceeds an upper threshold value. The integration value formed in (b) represents a measure of the power integrated over time and can thus be used at least approximately as a measure of the temperature of the instrument. The automatic reduction in the power or energy fed to the motor performed in (c) can therefore effectively act against a further increase in temperature or allow cooling if the temperature of the instrument exceeds an upper threshold value. In this manner, the risk of damage due to excessive temperature of the instrument can be effectively reduced.
摘要:
A motor-driven handpiece, which has a grip sleeve with a head area for mounting a tool, in particular for the preparation of tooth substance and/or bone substance, in which the head area is at least partially surrounded or encapsulated by a thermoplastic material which, compared to the material of the rest of the grip sleeve, has a lower thermal conduction value.
摘要:
A device for disinfecting, sterilizing and/or maintaining medical, particularly dental, instruments comprises connecting units for connecting supply containers for media used by the device, in particular cleaning or care products, wherein the connecting units comprise control and/or identification means, which enable an identification of the supply container.
摘要:
In a medicinal or dental hand instrument (1) comprising a hand piece (2) and a handle (6) arranged on the hand piece (2), an outlet opening (5), arranged on the front side of the handle (6), for the outlet of an abrasive therapeutic agent and a transport fluid, and a coupling terminal (4) for coupling the hand instrument (1) to a supply line for at least one transport fluid, in particular water and/or air, wherein the coupling terminal (4) is a coupling component (14b) of a coupling (13), the coupling component (14b) is arranged on an insert piece (20) which can be plugged into a plug-in socket or plug-in recess (19) and in its end zone, facing away from the flow, has one or more coaxially or paraxially disposed, sealed pipe socket couplings (10), which each connect a feed line (9, 11) for the transport fluid to an ongoing feed line (21, 22).

摘要:
An assembly for removing a medium from a pressurized container, the assembly having a cut-off valve that is located on an outlet line for the container and a sensor for detecting the pressure prevailing in the container. The assembly is also provided with a control unit that controls the cut-off valve on the basis of the pressure determined by the sensor in order to remove the desired quantity of medium.
摘要:
The invention relates to a medical or dental-medical instrument (2) having a memory element (10p) for identification and/or operational parameter data. IN order to extend the range of possible applications of the instrument, the memory element (10p) is constituted for the overwriting of the data by other data.
摘要:
A conditioning device for disinfecting, sterilizing and/or maintaining medical, especially dental, instruments comprises a distributor unit for supplying cleaning or maintenance media to the instruments, said distributor unit having respective inlets for every medium, said inlet being connected to a support for an instrument via a valve. Every valve comprises a sealing element which can be brought into a valve-opening position by means of the actuating element of the distributor unit which can be selectively positioned.
