Description

Technical field

The present invention relates to a medical treatment system with a connection device for the detachable fastening of peripheral components to a medical treatment device. Furthermore, the invention relates to a medical treatment device used therein and a peripheral component used therein.

State of the art

External treatment devices such as remote controls or other input devices are regularly used in treatment and analysis devices in medical or laboratory technology. These are often held or attached to the treatment or analysis device during use. Functional devices such as, for example, examination devices in the form of blood pressure measuring devices are also known, which are decoupled from the treatment device during their use, but are attached to the treatment device for the analysis of information obtained in use or, if they are not in use. Such components or functional devices which can be fastened to an outer surface of the treatment device and which, for example, also represent optional components for the treatment device, are referred to herein as peripheral components.

From the prior art, such as from the DE 10 2010 043 574 A1 or the DE 10 2009 024 448 A1 , Holding devices are known, which are set up for releasably fastening peripheral components to a treatment device. Such holding devices are usually designed for a special peripheral component and firmly connected to a housing of the treatment device, for example by means of a screw, adhesive or plug connection.

A retrofitting or retrofitting of the treatment device can accordingly result in the housing of the treatment device having to be mechanically converted, for example in that housing parts have to be replaced or drilled. Furthermore, connection points between the holding device and the housing of the treatment device have edges which are particularly susceptible to dirt due to difficult cleaning and disinfection. This fact can be undesirable especially for treatment devices in the field of medical and laboratory technology.

Presentation of the invention

Starting from the known prior art, it is an object of the present invention to propose an improved connecting device for releasably attaching peripheral components to a medical treatment device, which provides a flexible mechanical interface between the treatment device and the peripheral component that is optimized for this use.

The object is achieved by a medical treatment system with a connecting device with the features of claim 1. Advantageous further developments result from the subclaims, the present description and the figures.

Accordingly, a medical treatment system with a medical treatment device, a peripheral component and a connecting device is proposed, the connecting device being designed for releasably fastening the peripheral component to the treatment device. The connecting device comprises a first connecting element on the treatment device side and a second connecting element complementary thereto on the side of the peripheral component, the first and the second connecting element being able to be non-positively connected to one another on a coupling surface. The connecting device is characterized in that, in order to produce the non-positive connection, the first connecting element has at least two magnetic elements of opposite polarity along the coupling surface and the second connecting element has at least two magnetic elements complementary to these.

The proposed connecting device uses a force fit induced by magnetic attraction forces in order to couple a peripheral component to the treatment device. This enables simple and cost-effective attachment and detachment of peripheral components to the treatment device, in particular in comparison to screw, adhesive and plug connections known from the prior art. Accordingly, medical treatment devices equipped with such a connecting device can be converted and / or retrofitted without great effort, as a result of which their configurability is increased. In this way, a flexible mechanical interface is also provided for attaching interchangeable peripheral components to a treatment device.

Peripheral components that can be attached to the treatment device and are designed differently depending on the desired application - for example, a remote control equipped with a screen or only a keyboard - which are each equipped with a second magnetic connecting element on the component side, can alternately be attached to the magnetic connecting element on the device side ,

The use of magnetic connecting elements has the effect that magnetic attraction forces can be transmitted without contact to ensure the force-locking connection. This enables the first connection element and the second connection element to be arranged in each case within the treatment device or the peripheral component. In other words, the connecting elements can be integrated within the components to be connected, so that no edges are to be provided in the area of the coupling surface. The integration can take place, for example, by the connection element being accommodated in an already existing housing.

As a result, the housing, both of the treatment device and of the peripheral component, can (also) be smooth in the area of the coupling surface and therefore less susceptible to dirt. This is particularly advantageous for the use of the treatment device in the field of medical and laboratory technology.

For example, the magnetic elements of the first connecting element can be arranged within a housing of the treatment device, in particular at a distance from an outer surface of the treatment device. Accordingly, the magnetic elements of the second connecting element can be arranged within a housing of the peripheral component, in particular at a distance from an outer surface of the peripheral component. The outer surface of the housing of the treatment device can form the coupling surface of the first connecting element. Alternatively or additionally, the outer surface of the housing of the peripheral component can form the coupling surface of the second connecting element.

Furthermore, the coupling surface between the first and the second connecting element can be flat or curved. Such a design of the coupling surface ensures good accessibility to the entire coupling surface and thus facilitates cleaning and disinfection of the connecting device. By providing a curved coupling surface between the connecting elements, in addition to the non-positive connection, a positive connection between the components can also be provided. This contributes to a design of the connecting device that is optimized for the flow of force. In other words, a curved design of the coupling surface is suitable for solving the conflict of objectives of providing a coupling surface that is easily accessible for cleaning and disinfection and at the same time optimized for the flow of force.

As described above, the proposed connecting device of the medical treatment device is characterized in that the first connecting element has at least two magnetic elements of opposite polarity along the coupling surface. Correspondingly, the second connecting element has at least two magnetic elements complementary to the magnetic elements of the first connecting element. In other words, the second connecting element also has at least two magnetic elements of opposite polarity along the coupling surface. When the first and second connecting elements are connected to one another, they are preferably arranged such that the magnetic elements of the first and second connecting elements are aligned with one another. More precisely, in this state, oppositely polarized magnetic elements of the first and second connecting elements are preferably opposed to one another on the coupling surface.

For example, the first connecting element can comprise a first magnetic element with a north polarity facing the coupling surface and a second magnetic element with a south polarity facing the coupling surface. Complementary to this, the second connecting element can likewise comprise a first magnetic element with a north polarity facing the coupling surface and a second magnetic element with a south polarity facing the coupling surface. When the first and second connecting elements are connected to one another, they can be arranged relative to one another in such a way that magnetic elements in each case face opposite polarity on the coupling surface and thus exert a magnetic attraction force on one another.

The configuration and arrangement of the magnetic elements has the effect that a relative orientation and / or a relative position are / are fixed in the interconnected state of the connecting elements. As a result, the connecting device establishes a coupling position between the connecting elements without having to resort to a positive connection, for example in the form of mutually complementary grooves and pins. In the present case, the coupling position describes a relative position between the first and the second connecting element, in which oppositely polarized magnetic elements of the first and the second connecting element face each other on the coupling surface.

By providing the oppositely polarized magnetic elements, a rotational orientation of the peripheral component relative to the treatment device can also be determined, and depending on the pattern that the magnetic elements of the first and second connecting elements form, more than one stable rotational orientation can also be defined.

If it is provided that more than one peripheral component is alternately attached to the device-side connecting element, the device-side connecting element can also have magnetic elements in a superordinate pattern, and the different peripheral components can each have magnetic components with different partial patterns, so that the different peripheral components can be arranged in different orientations.

In other words, the connecting device is preferably designed such that the magnetic elements fix or code at least one relative coupling position between the first connecting element and the second connecting element. In the present case, “coding” of the connecting device is understood to mean at least one coupling position defined by the connecting device, in which a relative position and orientation of the connecting elements and thus also the relative position of the peripheral components in each case relative to the treatment device is defined.

The connecting device is preferably designed in such a way that, in the fixed, ie coded, coupling position, a sufficiently large holding force is provided to maintain the non-positive connection, but at the same time a simple release of the connecting elements can be ensured. Because the connecting elements in the proposed connecting device are equipped with the mutually complementary magnetic elements, a magnetic holding force is induced, the magnitude of which is influenced by the relative position of the connecting elements. This enables the connecting device to encode a predetermined coupling position on the one hand, without, however, completely blocking a relative translational movement along the coupling surface or a relative rotary movement in order to completely block a surface-normal of the coupling surface of the connecting elements, as is the case, for example, when using a coding caused by form-locking elements is. As a result, a sufficient holding force can be provided in the coupling position of the connecting elements and at the same time a simple release of the connection can be ensured. This can be achieved, for example, by rotating the connecting elements relative to one another.

Correspondingly, the connecting device can be designed such that, in a state in which the coupling surface is in contact with one another, the first connecting element and the second connecting element can be moved, in particular rotated, relative to one another between a coupling position and a removal position. As already described above, the coupling position specifies a relative position of the connecting elements, in which the magnetic elements of the first connecting element are each aligned with the complementary magnetic elements of the second connecting element. The removal position describes a relative position of the connecting elements, in which the magnetic elements of the first connecting element are arranged offset to the complementary magnetic elements of the second connecting element. The magnetic connecting force induced by the magnetic elements is correspondingly reduced in a state arranged in the removal position relative to the state of the connecting elements arranged in the coupling position. In the removal position, the connecting elements can therefore be detached from one another more easily or with less effort. For example, the connecting device can be provided such that the connecting elements for taking the removal position can be pivoted relative to one another about a surface normal of the coupling surface. In this way, the connection between the connecting elements can be released by a user using leverage.

In the connecting device proposed here, no interlocking form-locking elements are required to determine the coded coupling positions, such as in the form of pins or grooves provided on the coupling surface. Such components are usually prone to breakage. Correspondingly, the connecting device proposed here makes it possible to dispense with break-prone components for fixing at least one coded coupling position and can thus have greater operational reliability than known arrangements.

The at least two magnetic elements of the first and / or the second connecting element can each form a magnetic pattern. In other words, the at least two magnetic elements of the first and / or the second Connecting element in the form of a magnetic pattern. In the present case, a “magnetic pattern” is understood to mean an arrangement of the different magnetic elements that is defined in a plane and / or spatially, in particular along the coupling surface. A magnetic pattern preferably comprises at least two defined magnetic zones of opposite polarity, each of which can have a defined planar and / or spatial configuration. Each of the at least two magnetic zones is preferably formed by at least one of the at least two magnetic elements. The magnetic zones are preferably arranged spatially close to one another or essentially adjacent to one another. The magnetic zones can be designed differently. For example, the magnetic zones on the coupling surface can be of different sizes. The magnetic patterns formed on the coupling surfaces of the first and second connecting elements are designed to be complementary to one another. In particular, the magnetic pattern can have more than two magnetic zones on the coupling surface, for example four magnetic zones. The magnetic elements are preferably provided such that the at least two magnetic elements form a flat magnetic pattern with at least two ferromagnetic zones of opposite orientation or polarity on the coupling surface of the first and / or the second connecting element.

Such magnetic patterns can be distinguished from conventional magnet arrangements in that the magnetic zones can be spatially close to one another or essentially adjacent to one another. This has the effect that their magnetic field lines do not protrude as far and strongly into the surrounding space. In other words, the magnetic patterns described here can provide more compact and denser magnetic field lines, which is achieved in particular by magnetic zones arranged close to one another or magnetic elements of opposite polarity arranged closely next to one another. This property is particularly advantageous if electronic devices or components are to be held or fastened to the treatment device by means of the connecting device, since a distance can be reduced to avoid interference caused by magnetic field lines of the magnetic elements.

Such a configuration of the magnetic pattern enables a higher degree of freedom in the arrangement of the magnetic elements on the coupling surface of the respective connecting elements. Accordingly, complex arrangements of magnetic elements for coding coupling positions can be provided with a simultaneously compact construction of the connecting elements. This is in turn due to the property of the magnetic pattern that magnetic zones or magnetic elements of opposite polarity can be arranged particularly close to one another or adjacent to one another.

The different magnetic patterns mentioned can also be used to produce unambiguous assignments between connecting elements, for example in order to be able to attach different peripheral components only to an intended position on the treatment device, but not to another. This can be of importance if two or more peripheral components are to be fixed at predetermined positions on the treatment device and an exchange of the positions is not desired.

A certain positioning for different peripheral components can also be achieved via the different magnetic patterns - for example a first position for a first peripheral component and a second position for a second peripheral component. Different numbers of positions can also be provided for different peripheral components - for example, a first position for a first peripheral component and a position rotated by 180 ° to this, and a first position and two further positions, each 120 ° to the first position, for a second peripheral component rotated positions.

In a further development, the number of magnetic elements of the first connecting element can be different from or equal to the number of magnetic elements of the second connecting element.

For example, the first and / or the second connecting element can comprise at least three magnetic elements, it being possible for at least two of the three magnetic elements to have opposite polarity. In that more than two magnetic elements are provided on at least one of the two connecting elements, the connecting elements can be connected to one another in more than one coupling position.

The first connecting element and the second connecting element can be connectable to one another in a first coupling position and in a second coupling position, a relative orientation and / in a state arranged in the first coupling position relative to a state arranged in the second coupling position of the first and second connecting elements. or a relative position between the the first and the second connecting element, in particular between their magnetic elements, can be different. In this case, the first connecting element and the second connecting element can be movable, in particular rotatable, relative to one another between the first coupling position and the second coupling position in the state in which they are in contact with one another on the coupling surface. In addition, the connecting elements can be connectable to one another in further coupling positions, wherein a relative position or orientation of the connecting elements in each of the further coupling positions can differ from one another.

In a further development, the first and / or the second connecting element can comprise at least three magnetic elements, wherein the magnetic elements of a connecting element can be arranged along the coupling surface in such a way that in a first direction along the coupling surface at least two of the three magnetic elements next to one another or offset from one another are arranged and along a second direction along the coupling surface two of the three magnetic elements are also arranged side by side or offset from one another. The first direction and the second direction can be offset with respect to one another or perpendicular to one another along the coupling surface. In this way, a two-dimensional magnetic pattern of the first and / or the second connecting element can be spanned along the coupling surface. A two-dimensional magnetic pattern can be understood to mean, for example, a magnetic pattern in which the orientation or polarity of its ferromagnetic zones changes along a first direction and along a second direction perpendicular thereto.

Alternatively or additionally, the medical treatment system, in particular the medical treatment device or the connecting device, can comprise a sensor unit for detecting a connection between the first and the second connecting element. More precisely, the sensor unit can be set up to detect a relative alignment and / or a relative position and / or a coupling position between the first and the second connecting element. For this purpose, the sensor unit can comprise at least one Hall sensor. In particular, the Hall sensor can be set up to measure magnetic fields incident in its surroundings and, in response, detect a connection between the connecting elements. The use of at least one Hall sensor is based on the knowledge that the intensity and orientation of the magnetic field lines of the magnetic elements change in the connection device proposed here as a function of the relative position and orientation of the connection elements, in particular depending on whether they are arranged in a coupling position or not , Due to this change in the magnetic field lines, which causes a weakening or strengthening of the magnetic field lines measured by the Hall sensor, a connection state between the connecting elements can be determined.

Alternatively or additionally, the sensor unit can be set up to determine information relating to the peripheral component when the first and second connecting elements are connected to one another. For example, the transmission unit can be set up to identify a type of the peripheral component. For this purpose, the transmission unit can be encompassed by the medical treatment device, in particular the first connecting element.

Correspondingly, different magnetic patterns of different peripheral components can also serve to identify the respective type of peripheral components.

In a further development, an interface can be provided between the first connecting element and the second connecting element. The interface can be, for example, an electrical and / or an inductive and / or an optical interface. Furthermore, the interface can be set up in the interconnected state of the first and the second connecting element for data and / or energy transmission. In particular, contactless data and / or energy transmission can take place in this way.

Alternatively or additionally, the connection device can be set up to control a transmission via the interface between the connection elements as a function of the values detected by the sensor unit. More specifically, the sensor unit can be configured to control a transmission via the interface between the first and the second connection element in response to the information detected by the sensor unit regarding the connection between the first and the second connection element and / or the peripheral component.

In this way, for example, the coupling position between the first and the second connecting element detected by the sensor unit can be used to control the data and / or energy transmission via the interface and thus, for example, to control the peripheral component.

The above task is still solved by a medical Treatment device with a magnetic connecting element for detachably attaching peripheral components with the features of claim 14 and by a peripheral component for a medical treatment device with a magnetic connecting element for releasably attaching the peripheral component to the treatment device with the features of claim 16. Advantageous further developments result from the subclaims as well as the present description and the figures.

The medical treatment device and / or the peripheral component can / can be used in particular in the medical treatment system described above. The features described above in connection with the medical treatment system, in particular with regard to the connecting device, are accordingly also considered to be disclosed for the medical treatment device and the peripheral component.

Accordingly, a medical treatment device with a connecting element for releasably attaching peripheral components to the treatment device is proposed. The connecting element is designed to be non-positively connected on a coupling surface to a complementary connecting element, the further connecting element being assigned to the peripheral component. For this purpose, the connecting element comprises at least two magnetic elements of opposite polarity along the coupling surface, which are complementary to at least two magnetic elements of the further connecting element.

The connecting element of the medical treatment device can form part of the connecting device described above in connection with the medical treatment system.

In a further development, the medical treatment device, in particular the connecting element, can comprise a sensor unit for detecting a coupling to the further connecting element. As an alternative or in addition, the treatment device, in particular the connecting element, can comprise an interface element which, in a state coupled to the further connecting element, is set up for data and / or energy transmission to or from the further connecting element.

Accordingly, a peripheral component for a medical treatment device is also proposed, which is equipped with a connecting element for releasably fastening the peripheral component to the treatment device. The connecting element can be non-positively connected on a coupling surface with a complementary further treatment element on the treatment device side. Along the coupling surface, the connecting element comprises at least two magnetic elements of opposite polarity, which are complementary to at least two magnetic elements of the further connecting element.

The connecting element of the peripheral component can form part of the connecting device described above in connection with the medical treatment system.

In a further development, the peripheral component, in particular the connecting element, can comprise an interface element which, in a state coupled to the further connecting element, is set up for data and / or energy transmission to or from the further connecting element.

In all embodiments of the present medical treatment systems with a medical treatment device and a peripheral component, medical treatment devices and peripheral components, the magnetic elements or magnetic patterns of the connecting elements can be designed particularly advantageously such that when a connecting element is rotated relative to a complementary connecting element, the two connecting elements on a coupling surface are in contact, the resulting magnetic forces are always attractive. Complementary connecting elements in contact with one another on a coupling surface are thus magnetically attracted in any rotational orientation. Magnetic elements or magnetic patterns of this type ensure that there is no repulsion in any rotational position of the complementary connecting elements. This makes it possible for interconnected complementary connecting elements of a connection to be gradually rotated relative to one another without the connection of the connecting elements formed by magnetic attraction being separated. The gradation depends on the complementary magnetic patterns. In embodiments of present medical treatment systems with a medical treatment device and a peripheral component, medical treatment devices and peripheral components which have more than one coupling position in different relative rotational orientations of the connecting elements to one another, the coupling positions can be characterized in that the resulting magnetic attraction force between the connected complementary connecting elements is larger in some rotating orientations than in neighboring rotating orientations. In other words, the coupling points are distinguished by the fact that they have local maxima of the resulting magnetic attraction forces, in particular if the attraction force is plotted against rotation of the connecting elements relative to one another, for example parameterized via an angle of rotation.

Detailed description of preferred embodiments

Preferred exemplary embodiments are described below with reference to the figures. Identical, similar or equivalent elements in the different figures are provided with identical reference numerals, and a repeated description of these elements is partially omitted in order to avoid redundancies.

In 1 is schematically a medical treatment system with a medical treatment device 10 , a peripheral component 14 and a connector 12 for detachable fastening of the peripheral component 14 on the treatment device 10 shown. The treatment device is more precise therein 10 and the peripheral component 14 illustrated in an unconnected state. In other words, the peripheral component 14 not on the treatment device 10 attached.

The medical treatment device 10 can be, for example, a blood treatment device, for example a device for adsorption therapy, a dialysis device, an infusion device, or a device for plasmapheresis. The peripheral component 14 can, for example, be outside the treatment device 10 arranged external functional device, for example a blood pressure monitor. The peripheral component is corresponding 14 set up to be mechanically in use by the treatment device 10 to be decoupled to measure a patient's blood pressure. After the measurement, the peripheral component can 14 on the treatment device 10 attached and coupled to this, for example, the values measured in use for the blood pressure to the treatment device 10 to hand over and on the other hand to an energy storage of the peripheral component 14 charge.

For mechanical coupling of the peripheral components 14 with the treatment device 10 comprises the connecting device 12 a first magnetic connector 16 on the treatment device 10 and a complementary second connecting element 18 on the peripheral component 14 that on a coupling surface 20 are non-positively connectable. The first connector 16 includes along the coupling surface 20 four magnetic elements arranged side by side 22 two of which have a north polarity, as indicated by the letter "N" in 1 indicated, and two a south polarity, as indicated by the letter "S" in 1 indicated, have. The second connector 18 includes along the coupling surface 20 also four magnetic elements arranged side by side 24 which are complementary to the magnetic elements 22 of the first connecting element 16 are trained. The second connecting element accordingly comprises 18 two magnetic elements 24 with one of the coupling surfaces 20 facing north polarity and two magnetic elements 24 with one of the coupling surfaces 20 facing south polarity.

In the 1 are the respective coupling surfaces of the treatment device 10 and the peripheral component 14 book-shaped against each other shown unfolded so that the two coupling surfaces 20 point towards the viewer.

The connection device shown here 12 is a magnetic connector that connects through the magnetic elements 22 . 24 induced adhesion between the first and the second connecting element 16 . 18 uses the peripheral component 14 on the treatment device 10 to fix.

2 shows a state of the treatment device 10 in which the peripheral component 14 on the treatment device 10 by means of the connecting device 12 is attached in a first coupling position. The treatment device 10 and the peripheral component 14 are shown therein in a longitudinal sectional view. Opposite the in 1 shown representation is the peripheral component 14 in the first coupling position by 180 ° about a vertical axis relative to the treatment device 10 turned.

As in 2 shown is the first connector 16 in the treatment device 10 integrated and the second connecting element 18 is in the peripheral component 14 integrated. The magnetic elements are more precise 22 of the first connecting element 16 inside a housing 26 the treatment device 10 arranged so that it is spaced from the coupling surface 20 are arranged. The magnetic elements are corresponding 24 of the second connecting element 18 inside a housing 28 the peripheral component 14 arranged so that it is spaced from the coupling surface 20 are arranged. In this way, outer surfaces of the treatment device form 10 and the peripheral component 14 each the connecting elements 16 . 18 assigned coupling surfaces 20 ,

In the exemplary embodiment shown here, the respective coupling surfaces are 20 of the first and the second connecting element 16 . 18 just trained. In an alternative embodiment, the coupling surfaces 20 be arched.

In the in 2 The first coupling position shown are the first and the second connecting element 16 . 18 arranged to each other in such a way that oppositely polarized magnetic elements 22 . 24 on the coupling surface 20 face each other and thus exert a magnetic attraction on each other. In this coupling position there is a relative position and a relative alignment between the connecting elements 16 . 18 through the magnetic elements 22 . 24 established. In other words, the magnetic elements are in the coupling position shown 22 . 24 provided such that this has a relative position and orientation of the connecting elements 16 . 18 encode.

The first connector 16 and the second connector 18 are in the form of flat magnetic patterns with four. The magnetic patterns of the first and second connecting elements thus formed 16 . 18 are complementary to each other. The magnetic pattern of the first and second connecting elements 16 . 18 is along the coupling plane 20 provided such that in a first direction along the coupling surface 20 , as in 1 indicated by arrow A, two magnetic elements 22 or magnetic zones of opposite polarity are arranged one after the other. Furthermore, along a second direction perpendicular to the first direction along the coupling surface 20 , as in 2 indicated by arrow B, two magnetic elements 22 or magnetic zones of opposite polarity arranged one after the other.

In the exemplary embodiment shown here, the first connecting element comprises 16 the same number of magnetic elements as the second connecting element 18 , Alternatively, the number of magnetic elements 22 of the first connecting element 16 differ from the number of magnetic elements 24 of the second connecting element 18 differ. For example, the first and the second connecting element 16 . 18 more than four magnetic elements each 22 . 24 include.

In the exemplary embodiment shown here, the connecting elements 16 . 18 Are arranged regularly within a circular area, enables the connecting device 12 that the peripheral component 14 both in the first coupling position, as in 3 shown, as well as in a second coupling position, as in 4 shown, can be arranged. The peripheral component is in a state in the first coupling position relative to a state in the second coupling position 14 thereby a surface normal of the coupling surface 20 swiveled by 180 °, as if 3 and 4 evident. In other words, the first connector 16 and the second connector 18 can be connected to one another both in the first coupling position and in the second coupling position, with a relative alignment of the connecting elements 16 . 18 is different in the respective coupling positions. The magnetic elements are in the first and second coupling positions 22 of the first connecting element 16 each to the complementary magnetic elements 24 of the second connecting element 18 aligned and are thus on the coupling surface 20 across from.

As in 5 shown are the peripheral components 14 relative to the treatment device 10 and accordingly the first connecting element 16 relative to the second connector 18 can be positioned in a removal position. The magnetic elements are in the removal position 22 of the first connecting element 16 offset to the magnetic elements 24 of the second connecting element 18 staggered. In this position it is due to the magnetic elements 22 . 24 induced magnetic attraction compared to the coupling positions lower, so that a loosening of the peripheral component 14 from the treatment device 10 with less effort for a user.

As indicated by arrows C in 3 to 5 indicated, are the first connecting element 16 and the second connector 18 and thus the treatment device 10 and the peripheral component 14 in one on the coupling surface 20 adjacent state can be pivoted relative to one another between the first coupling position, the second coupling position and the removal position. In particular, the first connecting element 16 relative to the second connector 18 and thus the treatment device 10 relative to the peripheral component 14 around a surface normal of the coupling surface 20 pivotable to be moved into one of the positions.

As in 1 shown includes the connector 12 a sensor unit 30 for detecting a relative alignment, a relative position and thus a coupling position between the first connecting element 16 and the second connecting element 18 and thus between the treatment device 10 and the peripheral device 14 , For this purpose, the sensor unit comprises 30 two in the case 26 the treatment device 10 opposite to the first connecting element 16 arranged Hall sensors 32 . 34 , The Hall sensors 32 . 34 are set up depending on one on the peripheral component 14 arranged position magnets 36 a relative position between the peripheral component 14 and the treatment device 10 to determine.

If the peripheral component 14 in the second coupling position on the treatment device 10 is arranged, is the position magnet 36 opposite to the first Hall sensor shown to the left of the first connection unit in the view of FIG 32 arranged. In this case, the first Hall sensor detects 32 the magnetic field lines of the position magnet 36 and can determine that the peripheral component 14 is arranged in the second coupling position.

Is the peripheral component 14 however, arranged in the first coupling position, is the position magnet 36 opposite to the second Hall sensor 34 arranged. In this case, the second Hall sensor detects 34 the magnetic field lines of the position magnet 36 and can determine that the peripheral component 14 is arranged in the first coupling position.

Furthermore, the sensor unit 30 to be set up, the peripheral component 15 identify relevant information.
