Description

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. In recent years, 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. Such 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.

On the basis of the prior art, 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.

The object is achieved by an instrument carrier according to claim 1 and by a treatment device according to claim 10. Further advantages and features emerge from the subclaims and the following description of preferred embodiments of the inventive subject matter with reference to the accompanying figures. Individual features of the individual embodiment can be combined with one another within the scope of the invention.

According to a first aspect of the present invention, 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.

Compared to the treatment devices known from the prior art, it is provided according to the invention that the instrument carrier has an interface for connecting the modular secondary instrument so that the modular secondary instrument can use, for example, at least one supply line, in particular a first and / or second supply line, which is provided by the treatment device, in particular the instrument carrier. It proves to be particularly advantageous that the secondary instrument has a modular design, i.e. With the exception of the first and / or the second supply line, essentially all functional elements for the prophylaxis treatment, such as. B. a mixing chamber are arranged outside of the instrument panel, so that easy maintenance and / or cleaning of the secondary instrument is possible. This is particularly advantageous if 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.

Instead of being integrated into the treatment facility, provision is therefore made for the modular secondary instrument to be arranged on the outside of the instrument holder using the interface. For example, the secondary instrument is arranged on the instrument carrier. It is also possible that 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. It is also conceivable that the modular secondary instrument is permanently connected to the instrument carrier of the treatment device.

Furthermore, it is provided that the primary instrument is provided essentially as a hand-held device, while the secondary instrument has its own hand-held device in addition to a hand-held device, which is provided in particular to emit a powder-gas mixture. The hand-held device of the secondary instrument is preferably arranged next to the primary instruments, in particular next to the primary instruments provided as hand-held devices. For example, the primary instruments and the hand-held device of the secondary instrument are suspended from or attached to a common bar or a common side section of the instrument carrier, preferably in corresponding recesses or notches, so that the user can quickly switch between the primary instruments and the hand-held device of the secondary instrument .

It is also conceivable that a valve, preferably a proportional valve and particularly preferably a pinch valve, is provided for setting an amount of a powder-gas mixture to be ejected from the powder jet device, the valve being arranged outside the instrument panel. The valve is preferably a pinch valve which comprises a hose, the cross section of which is adapted to the current requirements of the powder-gas mixture to be ejected. Furthermore, it is provided that 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.

Furthermore, 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 hand-held device assigned to the secondary instrument then ejects the powder-gas mixture when needed.

Particularly preferably, the valve is integrated in a connection element, via which, for example, the hand-held device assigned to the secondary instrument can be connected to the instru ment carrier, in particular releasably, or via which the connecting line is connected or can be connected to the secondary instrument or to the instrument carrier. This significantly simplifies access to the valve. This proves to be particularly advantageous because these valves are maintenance-intensive and, in the event of a defect, lead to a large amount of contamination from flying powder. Correspondingly, this design allows easy access to the valve, in particular without opening the instrument carrier or even the secondary instrument.

Furthermore, it is conceivable that the secondary instrument is placed or arranged in a fixed area on the instrument carrier and during operation (with the exception of a hand-held device assigned to the secondary instrument) is arranged immovably relative to the instrument carrier. For example, 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).

The primary instrument differs from the modular secondary instrument in particular in that it is an integral part or largely an integral part of the treatment device. For example, only head elements or attachments such. B. an angle piece, exchange, for example, no function-triggering effect, such. B. a motor for driving or a preparation of media for treatment have. For example, motors and / or drives are integrated into corresponding handheld devices of the primary instrument, which are a fixed or integral part of the treatment device, or are integrated into the treatment device. In contrast to this, in the modular secondary instrument, the preparation of the medium, for example the mixing of a powder with a gas to form a powder-gas mixture, is provided within the modular secondary instrument and is therefore not carried out in the instrument holder or the treatment device.

The secondary instrument is preferably a powder jet device which, for example, has a mixing chamber and / or a hand-held device or a handpiece and is provided to emit a powder-gas mixture via a jet nozzle, which is in particular surrounded by a liquid jacket. Such powder blasting devices are used for the gentle removal of impurities or biofilms that form on teeth. According to a preferred embodiment, it is provided that the instrument holder, in particular the interface on the instrument holder side, is used to connect the secondary instrument

- a mechanical fixing mechanism and / or

- At least one first connection for connecting, in particular reversible connection, a first supply line with a first coupling component of the secondary instrument and / or a second connection for connecting, in particular reversible connection, a second supply line with a second coupling component of the secondary instrument and / or

- An electrical connection for power supply and / or information exchange

having.

In particular, it is provided that the secondary instrument, i. E. the modular secondary instrument that can be positioned permanently on the instrument carrier. In addition, the instrument carrier acts positively and / or non-positively in the interface area with the powder jet device or the secondary instrument, e.g. B. with its housing together. It is for example conceivable that a latching mechanism, clip mechanism, magnetic fixation and / or a Velcro fastening system is provided with which a mechanical connection or fixation between the secondary instrument and the instrument carrier is possible.

In addition, it is provided that the secondary instrument can be connected to the first supply line and / or the second supply line via the first connection and / or the second connection, whereby the operating resources required for operation can be made available to the secondary instrument. In particular, it is provided according to one embodiment of the invention that water is provided via the first supply line, in particular water at a pressure between 0 and 5 bar, in particular between see 1 and 4 bar and / or compressed air is provided via the second connecting line, in particular compressed air with a pressure between 2 and 8 bar. In addition, it is provided, according to one embodiment of the invention, that, in the assembled state, a connection of a third connection line to a third coupling component of the powder jet device can be implemented via a third connection. Via the third supply line, for example, powder can be provided to the powder jet device at the third connection or a powder / air mixture can be discharged and fed to a handpiece on the treatment facility side. It is preferably provided that the first supply line, the second supply line and / or the third supply line run within the treatment device, in particular within the instrument carrier, and are connected, for example, to a central body of the treatment device.

Furthermore, it is provided that the interface on the instrument holder side has an electrical connection which allows the powder jet device to be supplied with energy. Alternatively or in addition, it is conceivable that an exchange of information, in particular a bidirectional data exchange, is possible between the secondary instrument and the instrument carrier or the treatment device via an electrical connection. This not only makes it possible to output control signals to the powder jet device, but it is also possible to receive information about the powder jet device. This makes it possible, for example, to detect malfunctions or an absence or presence of a certain secondary instrument. In addition, corresponding information on cleaning and maintenance, for example with regard to the times or the measures for cleaning and maintenance, can be provided via the electrical connection. It is also conceivable for the secondary instrument to be coupled to the instrument carrier automatically.

In particular, it is provided that the electrical connection in the interface area is in communication with a control unit of the treatment facility, in particular a central control unit of the treatment facility, z. B. a foot pedal. It is also conceivable, for example, that the treatment device, in particular the primary device, and at the same time the modular secondary instrument can be controlled via the control unit. In particular, the operation of the currently connected secondary instrument can be monitored or controlled via the control unit. A standardized protocol, such as a CAN bus, can be used for communication between the control unit and the secondary instrument. It is also conceivable that the communication takes place wirelessly. In a simple embodiment, the communication between the control unit and the secondary instrument can be limited to the forwarding of the activation signal of the secondary instrument.

It is particularly preferred that a device for removing tartar, in particular a piezoelectrically operated device for removing tartar, a so-called "scaler", is integrated into the treatment device as a primary instrument, or provided separately from the secondary instrument.

It is preferably provided that the first supply line and / or the second supply line and / or the third supply line has a non-return valve and / or the first and / or second and / or the third connection is designed as a plug-in mechanism and / or self-closing. In particular, the formation of a check valve in the first and second supply lines makes it possible to advantageously prevent backflowing media or operating resources from flowing into the treatment device via the interface on the instrument carrier side and contaminating it. A self-closing mechanism is preferably to be understood as such a mechanism in which one end of the first connection and / or the second connection is closed as soon as the secondary instrument is not connected. This in turn allows media or equipment to be prevented from entering the first supply line and / or the second supply line which are provided for the modular secondary instrument during operation. As an alternative, it is also conceivable that a flap is provided, which covers the instrument support side Interface terminates or covers. It is also conceivable that an insert is provided which is inserted into the interface on the instrument carrier side and fills it so that the instrument carrier without the modular secondary instrument provides a smooth surface for a doctor in charge.

In particular, a foot pedal is provided for controlling the primary instrument and / or the secondary instrument. It when the foot pedal is used to control both the primary instrument and the secondary instrument is particularly advantageous. The foot switch can in particular be a wireless foot switch that communicates via radio signals with the control device and / or the primary instrument and / or the secondary instrument to exchange information and control signals. The communication between the secondary instrument and the treatment facility can take place via a standardized protocol, e.g. via a CAN bus or Bluetooth.

In a preferred embodiment, the central control device takes over the control of the secondary instrument in that the central control device imitates the function of the foot switch and manages the secondary instrument as a further functional unit. E.g. the activation and / or control of the secondary instrument take place via the foot switch of the treatment device.

Furthermore, it is preferably provided that a fluid, in particular a liquid, which is provided to the modular secondary instrument on the instrument carrier via the first and / or second supply line, is provided by a water treatment system of the treatment device. In particular, the water treatment system of the treatment device is primarily intended for the primary instrument, in particular for the Fland instrument designed as a Fland device with a water outlet, which is provided for rinsing the oral cavity. Accordingly, the primary instrument and the secondary instrument advantageously share the water treatment system of the treatment unit. This means that the secondary instrument can also be integrated into the cleaning and disinfection programs of the treatment facility. Furthermore, it is preferably provided that the instrument carrier has a receiving area for the secondary instrument in the form of a recessed course on the outside of the instrument carrier. In particular, it is provided that the outside is shaped in such a way that the insertion or removal of the modular secondary instrument is simplified. This can be implemented, for example, in that the receding course enables an insertion or insertion, preferably a guided insertion or insertion, for the secondary instrument. Guide means can also be arranged, such as guide rails or guide pins, which make insertion or removal easier and ensure a reliable connection. Furthermore, it is preferably provided that the recessed course interacts positively and / or non-positively with the secondary instrument when the modular secondary instrument is installed, so that the modular secondary instrument is fixed to the instrument carrier. For example, the set-back course corresponds at least to a part of the housing bottom of the powder jet device. In particular, the receding course allows the secondary instrument to be inserted. It is also conceivable that the set-back course has, for example, an inclined bottom surface that favors the drainage of operating resources that may emerge from the powder jet device during operation.

In particular, it is provided that an interface on the instrument holder side and an interface on the powder blasting device side interact in the assembled state, in particular via the first connection, the second connection, the electrical connection and / or the mechanical fixing mechanism, in the sense of a key-lock mechanism. In other words: the interface on the powder blasting device side and the interface on the instrument holder side are designed to be complementary or compatible with one another, so that, for example, a first or second coupling component of the powder blasting device side can be plugged into the first connection and / or the second connection of the interface on the instrument holder side. The first connection and the second connection are correspondingly adapted to the first and / second coupling component of the powder jet device. For example, the first coupling component and the second coupling component of the powder jet device can be inserted into corresponding recesses on the instrument carrier-side interface, with a cross-section of the first coupling component and / or the second coupling component being matched in terms of dimension and geometry or designed as a function of the cross-section of a receiving area of the first and / or second connection in the area of the instrument carrier-side interface. This makes it possible to prevent the first supply line and / or the second supply line from being used for purposes that are not intended. For example, it is conceivable that the first and / or the second coupling component or the receptacle on the instrument carrier side of the first connection and the second connection have a first and / or a second filter, which are exchangeable. This makes it possible in an advantageous manner to provide filters in the interface area between the modular secondary instrument and the instrument carrier, which allow the operating resources, in particular the water and / or the compressed air, to be processed.

In a further embodiment, it is conceivable that the primary instrument or at least one of the primary instruments is designed such that the primary instrument provides the first connection and / or the second connection for connection to the first supply line and the second supply line. In other words: If the primary instrument is used, for example, for the water supply of the secondary instrument, it is conceivable that the operating medium is made available to the secondary instrument via a corresponding connecting line of the interface on the instrument carrier side. For this purpose it is necessary, for example, that the primary instrument provides the liquid or the fluid at a desired, required pressure that is suitable for the operation of the secondary instrument. The same applies to compressed air.

In a particularly preferred embodiment of the present invention it is provided that the secondary instrument has an output channel for supply of a hand-held device, the output channel being connected to the instrument carrier in the assembled state. In other words: the powder-gas mixture provided by the powder jet device and / or the liquid are fed back to the instrument carrier via the outlet channel and are made available from there to a corresponding hand-held device for emitting the powder-gas mixture. This has the advantage that all hand-held devices can be placed centrally at one point on the treatment unit, in particular on a common instrument carrier. Alternatively, it is conceivable that the hand-held device is connected directly to the secondary instrument and the corresponding output channel does not make a detour via the instrument carrier and / or the treatment unit.

It is preferably provided that the instrument carrier comprises a swivel arm and / or a displaceable trolley. It is particularly provided that the primary and secondary instrument are arranged together on an instrument carrier, or the modular secondary instrument is attached or arranged in the assembled state on its own instrument carrier and / or the primary instruments are part of a further instrument carrier. In particular, a swivel arm or a trolley allows any orientation of the instrument carrier, so that a user, in particular a treating physician, can align the instrument carrier with the secondary instrument so that optimal treatment is possible.

The swivel arm can be laterally displaceable, adjustable in height and its receiving area for the secondary instrument can also be designed to be rotatable and tiltable. The swivel arm is preferably arranged under the treatment chair.

It is preferably provided that the secondary instrument can be used independently of the treatment device. In other words: the secondary instrument is functional independently of the treatment device, provided that the corresponding operating means are made available to the secondary instrument. The treatment facility, in particular the instrument carrier, serves accordingly, in the present case only as a supply point that provides the necessary operating resources, ie liquid and gas, to the modular secondary instrument. In particular, due to the exchangeable or reversible arrangement of the secondary instrument on the instrument carrier, it is advantageously possible to simply exchange the secondary instrument and / or to separate it from the instrument carrier for maintenance work or cleaning purposes.

Another object of the present invention is a treatment device with an instrument carrier according to the invention, a powder jet device being arranged as a secondary instrument at the interface. All of the features and advantages described for the instrument wearer can be transferred analogously to the treatment facility and vice versa. The treatment device is preferably a treatment chair.

Further advantages and features emerge from the following description of preferred embodiments of the subject matter according to the invention with reference to the attached figures.

In the present example, the arrangement element 7 is arranged pivotably on the central body 8 of the treatment device 1. Furthermore, the treatment device 1 comprises an instrument holder 10 and a further instrument holder 10 '. The further instrument carrier 10 'is connected to the central body 8 via at least one joint and can be adjusted by means of the at least one joint, for example by means of a pivoting movement, into a desired position.

In particular, it is provided that the treatment device 1 comprises an instrument carrier 10, which is connected to the central body 8 via a swivel arm 15 and provides an interface for receiving a modular secondary instrument 12. In particular, it is provided in FIG. 1 that here the instrument carrier 10 is embodied separately from the further instrument carrier 10 ′ and / or preferably has a powder jet device as a modular secondary instrument 12. In particular, it is provided that the instrument carrier 10 can be pivoted via the pivot arm 15, and / or height-adjustable by means of a joint, and / or additionally rotatable about an axis of rotation R, in particular a vertically extending axis of rotation R, so that the instrument carrier 10 can be displaced in all three spatial directions with the modular secondary instrument 12 and, if necessary, can also be rotated about the axis of rotation R in order to be aligned in an optimal position for the treatment at any position next to the chair 5.

In particular, it is provided that the modular secondary instrument 12 has a hand-held device 13 with which both a powder-gas mixture and a Fluid, in particular a liquid, can be emitted via a jet nozzle. The emitted or ejected powder-gas mixture, in particular encased in a fluid flow, is then used in particular for tooth cleaning, in particular for prophylactic tooth cleaning, in which, for example, biofilms, tartar and / or the like is removed.

For this purpose, the modular secondary instrument 12 is designed as a powder jet device, which has, for example, a chamber for mixing the powder-gas mixture. In order to provide an interface for the secondary instrument 12 on the instrument carrier side, provision is made for the instrument carrier 10 to have at least one first connection and / or a second connection which ensure that the secondary instrument 12 is supplied with resources. For example, the first connection is used to connect the secondary instrument 12 to a first supply line on the instrument holder side and / or the second connection is used to connect the secondary instrument 12 to a second supply line on the instrument holder side. The first and second supply lines preferably run within the instrument holder 10 and / or the swivel arm 15 and / or the central body 8. For example, the first connection line provides compressed air, in particular for a pressure between 2 and 8 bar, and / or the second supply line provides water, in particular water with a pressure between 0 and 5 bar.

The operating means are provided to the secondary instrument 12 by the instrument carrier 10 via the first connection and the second connection. Furthermore, it is provided that the treatment device 1, in particular the instrument carrier 10, provides a further electrical connection (not shown) for the supply and / or for information exchange with the secondary instrument 12 in addition to the first connection and the second connection. For this purpose, for example, the corresponding first supply line and / or the second supply line and / or an electrical line run within the

Swivel arm 15, which is connected to the central body 8, up to the instrument carrier 10 and are there on the outside via the first connection, the second connection and / or the electrical connection to the secondary instrument 12 is provided. It is also conceivable that the primary instrument 11 is formed integrally with the further instrument carrier 11.

In Figure 2, a treatment device 1 is shown in accordance with a second embodiment of the present invention. The embodiment in FIG. 2 differs from that in FIG. 1 essentially only in that the instrument carrier 10 for the modular secondary instrument 12 is designed as a trolley 17. Such a trolley 17 has rollers 19 on its underside which allow it to be moved to any location. Via a central supply line 18, the trolley 17 is in direct connection with the central body 8, on which, for example, further primary instruments 11 are provided.

Furthermore, it is preferably provided that the treatment device 1 has a foot pedal 16, the foot pedal 16 being provided in particular for communication with the primary instrument 11 and / or the secondary instrument 12. It is conceivable, for example, that the foot pedal 16 is in wireless communication with the primary instrument 11 and / or the secondary instrument 12. Furthermore, it is provided that a control device is integrated in the instrument carrier 10 and / or the treatment device 1 with which both the primary instrument 11 and the secondary instrument 12 can be controlled. For example, a switch can be used to change the control between the primary instrument 11 and the secondary instrument 12. It is also conceivable that the instrument carrier 10 has a display, in particular a touch display, which provides the attending physician with information and / or the control of the primary instrument 11 and / or the secondary instrument 12 or communication with a central control unit the treatment facility 1 permitted.

In FIG. 3, an interface 35 on the powder blasting device side according to a preferred embodiment of the present invention is shown schematically. There FIG. 3 shows, in particular, an underside of the housing 20 of the modular secondary instrument 12.

In particular, the interface 35 on the powder blasting device side is designed as a recessed course in which a first coupling element 21 and a second coupling element 22 are provided, in particular formed on a rear wall of the recessed course in the housing 20 of the modular secondary instrument 12 recessed course for a mechanical fixation and / or coupling to the instrument carrier 10, for example to a correspondingly formed projection of the instrument carrier 10, use. In this case, it is preferably provided that a complementary interface on the instrument holder side is provided, which interacts with the interface 35 on the powder blasting device side in a form-fitting and / or force-fitting manner, in particular when the secondary instrument 12 is mounted. Furthermore, it is preferably provided that the first coupling element 21 and / or the second coupling element 22 is designed as a plug-in element, the first coupling element 21 engaging in the first connection and / or the second coupling element 22 in the second connection in the assembled state. is plugged in.

In this case, for engaging in the first connection and the second connection, these are preferably designed complementary to the first coupling element 21 and the second coupling element 22 as corresponding recesses in the interface on the instrument carrier side. In this way, a key-lock principle can be implemented in particular, which allows the modular secondary instrument 12 to be connected easily to the instrument carrier 10 and ensures that the correct secondary instrument 12 is connected to the instrument carrier 10.

FIG. 4 shows a further interface 35 on the powder blasting device side according to a second preferred embodiment of the present invention. in the The interface area on the powder blasting device side of FIG. 4 essentially corresponds to that of FIG. 3 and essentially only differs in that in the powder blasting device-side interface 35 of FIG. 4 it is additionally provided that the first coupling component 21 of a sleeve-like first filter 31 and the second coupling component 22 is encased by a sleeve sen-like second filter 32, in particular is partially encased. It is provided in particular that, in the assembled state, the first coupling component 21 and / or the second coupling component 22 reach through the first filter 31 and / or the second filter 32 accordingly. The first coupling component 21 and / or the second coupling component 22 are configured in such a way that a supply medium or operating medium, such as water and / or compressed air, enters the end face of the first coupling component 21 and / or the second coupling component 22, then performs a lateral offset in order to be passed through the first filter 31 and / or second filter 32. After flowing through the first filter 31 or the second filter 32, the operating medium is fed back into the first coupling component 21 and / or the second coupling component 22. In particular, the first filter 31 and the second filter 32 are designed to be interchangeable, so that the first filter 31 and / or the second filter 32 in the area of the first connection and the second connection or in the area of the first coupling component 21 and / or the second coupling component 22 can be easily and regularly exchanged, so that the powder jet device, ie the secondary instrument 12, permanently filtered operating media, in particular compressed air and / or liquid, can be made available.
