Definitions

  • Instrument carrier for a treatment device and treatment device with such an instrument carrier
  • the present invention relates to an instrument carrier for a treatment device, in particular a dental treatment device, and a treatment device with such an instrument carrier.
  • Such treatment devices are known, for example, from DE 10 2013 224 764 B1, EP 2 101 680 A1 or EP1 817 705 B1.
  • This is typically a central workstation and location where the patient is positioned in the dental practice for treatment.
  • This treatment facility is usually designed so that the entire range of dental services can be provided with it.
  • Almost all of the primary instruments and / or functionalities required for this are integrated in this treatment unit or are at least connected to it.
  • These are, for example, an adjustable mounting for the patient, lighting, camera system, sink, various turbine and motor connections, rinsing and / or suction devices.
  • the patient generally remains on the bed during treatment and is cared for or treated with the aid of the primary instruments that are arranged around him.
  • dental prophylaxis has become more and more important as an independent service.
  • the patient is examined in advance by a dentist and the general dental status is recorded. Then the teeth are cleaned and other prophylactic measures are taken to maintain oral health. This is usually no longer done by the dentist himself, it is taken over by a specially trained specialist, a dental hygienist.
  • Dental treatment facilities usually do not have a powder jet function, since the handling of the powder within the treatment facility is technically complex and leads to handling disadvantages.
  • powder jet devices are usually on a separate equipment cart next to the treatment unit or are placed on the shelf for dental instruments. Both have disadvantages.
  • the equipment trolley requires additional space, has to be supplied with electricity, water and compressed air, and the storage area is usually required to store dental instruments. It is therefore advantageous to provide a treatment unit that does not have these disadvantages.
  • the present invention therefore sets itself the task of improving the treatment devices known from the prior art, in particular with regard to their use for prophylaxis.
  • an instrument carrier of a treatment facility in particular a dental treatment facility, is provided, a primary instrument being provided on the treatment facility, at least part of the at least one primary instrument being an integral part of the treatment facility, characterized in that that the instrument carrier has an interface on the instrument carrier side for connecting, preferably reversible connection, a modular secondary instrument, the secondary instrument preferably being a powder jet device.

B. a mixing chamber are arranged outside of the instrument panel, so that easy maintenance and / or cleaning of the secondary instrument is possible.
  • the secondary instrument is a powder jet device for which easy access to the powder containers and / or the mixing chamber is necessary in order to enable refilling or cleaning. Accordingly, integration of the powder jet function in the treatment unit or in the instrument carrier can thus be advantageously avoided. This is particularly advantageous because in the event of a leak or defect in the powder jet line, considerable damage could occur in the treatment device. Any leaking resources can instead be easily removed from the instrument holder of the claims and / or the instrument holder, z. B. be wiped.
  • the modular secondary instrument is arranged on the outside of the instrument holder using the interface.
  • the secondary instrument is arranged on the instrument carrier.
  • the modular se- secondary instrument in the assembled state is attached to the side of the instrument carrier or is arranged.
  • a further advantage of the design of an interface on the instrument carrier is that an additional supply device or supply line or control device for the secondary instrument, that is to say formed outside of the treatment device or the instrument carrier, can be dispensed with, and this instead is in the treatment device or in Control devices of the treatment device can be integrated.
  • the modular secondary instrument is permanently connected to the instrument carrier of the treatment device.

  • the valve is arranged, viewed in the direction of flow, behind an area in which the powder and the gas are mixed to form a powder-gas mixture.
  • the valve in the secondary instrument can be be ordered, preferably in the area of an output channel or at an output of the secondary instrument, which in turn is connected to the instrument carrier via a hose, and / or in an output channel or in an output of the instrument carrier that connects the hand-held device of the secondary instrument to ver gas mixture supplied.
  • a connecting line is provided which connects the secondary instrument to the instrument holder and via which a powder-gas mixture is conveyed or routed from the secondary instrument to the instrument holder, the instrument holder in turn preferably being assigned to the secondary instrument, but particularly preferably on the instrument holder - permanent or detachable - connected or trained, hand-held device with the powder-gas mixture provides ver.

  • the secondary instrument has a base body that is larger than the extent of the primary instrument and is preferably arranged on the instrument carrier
  • the treatment device is preferably aimed at dental prophylaxis, in particular it is used exclusively for dental prophylaxis. Accordingly, in addition to a chair, lighting, a sink, a suction device, a hand-held device for emitting compressed air and / or water and a device for removing tartar using ultrasound (a so-called "scaler"), there is no further primary instrument for such a treatment device intended.
  • Further examples of primary instruments in other treatment facilities could be, for example, drilling instruments and / or grinding instruments (e.g. a contra-angle handpiece for polishing).
