摘要:
Method for maintaining and cleaning the conduits (2a, 3a) of a dental polisher (1), of the type that includes the pressurized spraying of a polishing powder (7) onto a tooth surface. The method includes an operational phase comprising the pressurized injection of a solution (9), in which the powder (7) is soluble, into at least some of the conduits (2a, 3a) through which the powder (7) passes.
摘要:
The invention concerns a dynamometric key designed in particular for fixing an insert (22) on a handpiece (23). Said dynamometric key is characterized in that it consists of a grip element (3), and a securing element (5), said two elements being linked in frictional rotation via a spring (1) whereof the end coils have been assembled, so as to provide it with a globally toroidal shape.
摘要:
A microfiche reader provided with a keyboard of the type comprising a radiation emitter such as an infrared radiation emitter, each key being associated with an emitter modulation code and the modulated signal being detected by a photoreceiver. A microcomputer serves to decode the signal delivered by the photodetector and to generate suitable electrical signals for controlling drive motors which initiate the displacements of a microfiche support plate.
摘要:
A power cord (5) for a medical handpiece includes at least one longitudinal auxiliary housing (13) which is equipped with a radial slit (15) which communicates the auxiliary housing (13) with the exterior. The power card is equipped with a mechanism for positioning the flexible conduit inside the auxiliary housing, the mechanism including: elements (24) for positioning same on the cord (5), means for positioning the flexible conduit (17) at the inlet of the slit (15) of the cord (5), and applicator elements for pushing the conduit (17) into the auxiliary housing (13) through the slit (15) when the mechanism is moved along the length of the cord (5).
摘要:
A switching device for an irrigation line includes two flexible supply tubes (4a, 4b), each of the tubes connecting a flask containing an irrigation fluid to a handpiece via a peristaltic pump. The device includes at least one compression element (34a, 34b) and control members (32) which can apply the compression element alternatively to each of the flexible supply tubes (4a, 4b) in such a way as to squeeze and block the tube. The control members (32) are designed such that, when one of the tubes is being squeezed in order to block the passage of the fluid through same, the other tube is not being squeezed so that the fluid can flow through the other tube.
