Description

Technical Field

[0001] The present invention relates to a medical instrument comprising a basic instrument, a housing unit connectable to the basic instrument, and a user interface connectable to the basic instrument. Background Art

[0002] Due to the possibility of combining the basic device with different user interfaces and different housing units, the medical device can be adapted to different requirements.

[0003] DE 102018005280 B3 discloses a respirator as an example of a medical device. The device comprises a base device with a cover plate, a patient connection provided on the base device, and an operating unit provided on the cover plate. The respirator is designed so that the cover plate can be positioned at various angles relative to the vertical axis on the base device. To this end, the cover plate, as part of a user interface, is connected to the base device via multiple components in a rotatable and latchable manner.

[0004] A disadvantage of the respirator known from DE 10 2018 005 280 B3 is that the operating unit can be pivoted about the height axis of the basic device but cannot be removed without disassembling it. Therefore, the accessibility of this respirator is disadvantageously limited. Summary of the Invention

[0005] The object of the present invention is therefore to provide a medical device with which the housing unit and the user interface can be reliably connected to or released from a basic device in a particularly simple manner (for example during device assembly or in the event of maintenance).

[0006] These and further objects are achieved by the medical device according to the invention.

[0007] Additional advantages and features of the present invention are illustrated by the other embodiments, the description and the accompanying drawings.

[0008] According to the present invention, a medical device is provided. The medical device comprises a base device, a housing unit connectable to the base device, a user interface connectable to the base device, a plurality of connection units for reversibly connecting the base device to the housing unit and to the user interface, and a coupling device. The coupling device is configured to move the plurality of connection units from a released state to a connected state and vice versa.

[0009] Thus, a medical device can be provided that is reversibly connected to a housing unit and a user interface via a plurality of connection units provided on the device side. This improves the modularity of the medical device. Through the coupling device provided according to the present invention, the plurality of connection units provided on the device side can be moved into a connected state to connect with the housing unit and the user interface, or moved into a released state to release from the housing unit and the user interface. This allows for simple assembly and disassembly of the housing unit and the user interface, for example, to simplify assembly and / or maintenance of the medical device.

[0010] In this regard, the subject matter of the present invention supports the concept of modular construction of medical device series, by allowing, for example, prefabricated basic devices to be equipped with different user interfaces and, if necessary, different housing units in a downstream, customer-specific production step ("customization") with minimal assembly effort. This makes it easy to offer devices in different comfort and price classes from similar basic devices by varying the user interface (e.g., in terms of its size and adjustability relative to the basic device) and, if necessary, the housing unit.

[0011] Preferably, at least some of the several connecting units are provided on the instrument side, ie are designed as components of a medical instrument, in particular as components of a basic instrument.

[0012] For example, the medical device may be designed as a respiratory device or an anesthesia device and have corresponding components and interfaces for this purpose.

[0013] For example, when the medical device is designed as a respiratory device or an anesthesia device, it may have a blower for controlling and / or regulating the volume flow and / or pressure of the gas or gas mixture determined for breathing. In addition, the medical device may, for example, have a gas connection for supplying ambient air and / or compressed air and / or oxygen to the medical device. The medical device may also, for example, have one or more patient interfaces, such as inhalation and exhalation circuits. The medical device may also, for example, have a controller and / or an energy supply (such as a power grid connection and / or a battery and / or an accumulator). In particular, when the medical device is designed as a respiratory device or an anesthesia device, it may have additional pneumatic components, such as lines and valves (such as proportional valves, check valves, magnetic valves, etc.), for influencing the air flow from the medical device to the patient and from the patient to the environment or the medical device.

[0014] The basic device is used to accommodate at least the electronic components and preferably also the pneumatic components of the medical device. The basic device can be designed as an instrument chassis or comprise an instrument chassis and other components (eg attachments).

[0015] A user interface can be designed to input and / or output information to a user of a medical device, such as a physician. For example, a user interface can include a display (e.g., a screen) for presenting information. A user interface can include an operating unit, such as an input element (e.g., a knob, button, rotary switch, and / or a display, particularly a touch screen), for inputting information.

[0016] The released state is understood to be a state in which the housing unit and / or the user interface can be removed from the medical device. Accordingly, the connected state is understood to be a state in which the housing unit and / or the user interface cannot be removed from the medical device (in other words, locked).

[0017] According to the invention, the coupling device is a coupling device of a medical instrument, in other words, the coupling device is provided on the instrument side, in other words, a component of a medical instrument, preferably a component of a basic instrument.

[0018] The housing unit, the user interface, the connecting units and the coupling device can each be designed in multiple parts or in multiple components.

[0019] Several connecting units can be designed as a single unit or multiple units.

[0020] The coupling device preferably has several actuating elements for actuating the coupling device, wherein several actuating elements are not actuable without tools.

[0021] In this way, the safety of the medical device can be improved since unintentional actuation of the actuating element can be prevented.

[0022] The medical device preferably further comprises an openable cover which is designed to cover a number of operating elements in the closed state.

[0023] In this way, medical devices can be improved with regard to hygienic design.

[0024] For example, the cover can be designed as a housing segment, for example as a component of a housing unit, which can be fastened to the basic instrument or can be fastened to the basic instrument. For example, the cover can be connected to the basic instrument detachably (i.e., removably) so that the cover can be opened by removing or taking it off, or can be connected to the basic instrument pivotably, for example, by means of a hinge or articulation so that the cover can be opened by pivoting.

[0025] Preferably, the coupling device has several locking shafts, wherein each of the several locking shafts is rotatable about a corresponding central axis, so that the coupling device can be operated.

[0026] The provision of corresponding locking axes allows them to act simultaneously on multiple coupling devices, particularly those provided on the device, as long as these coupling devices are coupled, i.e., in interaction. In this regard, preferably, each of the several locking axes can engage with multiple connection units, particularly those provided on the device. In this way, multiple connection units, particularly those provided on the device, can be influenced by actuating just one of the several operating elements. This improves the handling of the medical device by shortening the time required for disassembly / assembly of the housing unit and / or the user interface.

[0027] Preferably, a portion of the plurality of connection units is designed as a plurality of connection units provided on the device side for reversibly connecting the basic device to the housing unit and reversibly connecting the basic device to the user interface. In addition, preferably, a portion (i.e., another portion) of the plurality of connection units is designed as a plurality of connection units provided on the user interface side for reversibly connecting the user interface to the basic device, wherein the plurality of connection units provided on the user interface side for connecting the user interface to the basic device can be connected to the plurality of connection units provided on the device side in a form-fitting manner.

[0028] In this way, the user interface can be easily associated with the basic device.

[0029] Within the scope of the present invention, a connecting unit provided on the instrument side is understood to be a connecting unit which is designed as part of the medical instrument, in particular as part of a base instrument.

[0030] The number of connection units provided on the user interface side may correspond to the number of connection units provided on the device side, or may differ therefrom.

[0031] Preferably, several connecting units provided on the device side are designed to enable removal or placement of the housing unit and removal or placement of the user interface along a common axis of the basic device, preferably along a height axis, in the released state.

[0032] In this way, the operability of the medical device during assembly and / or repair may be improved.

[0033] The height axis of the basic instrument is understood to be a vertically oriented axis of the basic instrument or the medical instrument relative to the orientation of the basic instrument or the medical instrument when installed in accordance with the instructions.

[0034] Preferably, the plurality of connection units provided on the device side are designed as a plurality. Furthermore, preferably, the plurality of connection units provided on the device side are evenly, in particular rotationally symmetrically, distributed around a common axis in order to provide (preferably correspondingly) a plurality of arrangements of user interfaces and / or housing units relative to the basic device.

[0035] In this way, the arrangement of the user interface and / or the housing unit relative to the basic device can be designed flexibly. For example, in this way, the patient interface and the user interface that can be provided on the basic device can each be positioned ergonomically and optimally (e.g., the patient interface toward the patient, the user interface toward the doctor).

[0036] Preferably, each of the several connection units provided on the user interface side has at least one connection portion groove. Furthermore, preferably, each of the several locking shafts has at least one section with a shaft groove. Furthermore, preferably, each of the several locking shafts is designed so that, by rotating the locking shaft, the at least one shaft groove can be aligned with one of the several connection portion grooves to provide a released state. Furthermore, preferably, each of the several locking shafts is designed so that, by rotating the locking shaft, the shaft groove cannot be aligned with one of the several connection portion grooves to provide a connected state.

[0037] In this way, a particularly simple possibility for realizing the release state and the connection state can be provided.

[0038] A connecting portion-groove is understood to be a groove in the connecting unit.

[0039] A shaft-groove is understood to be a groove in the locking shaft.

[0040] Particularly preferably, each of the plurality of locking shafts has at least two sections with shaft grooves. Furthermore, preferably, each of the plurality of locking shafts is designed so that, by rotating the respective locking shaft, the at least two shaft grooves can be brought into alignment with two corresponding connecting portion grooves of the plurality of connecting portion grooves to provide a released state. Furthermore, preferably, each of the plurality of locking shafts is designed so that, by rotating the respective locking shaft, the at least two shaft grooves cannot be brought into alignment with two corresponding connecting portion grooves of the plurality of connecting portion grooves to provide a connected state.

[0041] It is therefore particularly easy to have the locking shaft act simultaneously on at least two connecting units provided on the instrument side. This can improve operating effort.

[0042] Preferably, at least a portion of the connecting units provided on the user interface side has a contact surface for accommodating the housing unit in a clamping manner between the user interface and the basic device. In addition, preferably, the assembly in a clamping manner can be achieved by providing a connected state due to rotating a plurality of locking shafts.

[0043] In this way, the housing unit can be accommodated in a clamping manner between the user interface and the base device, wherein the clamping assembly can advantageously be effected essentially simultaneously with the provision of the connected state, ie without additional coupling manipulations.

[0044] Preferably, at least one sealing element is arranged between the connecting units provided on the device side and some or all of the contact surfaces, said sealing element being designed to indicate preload by establishing a clamping reception.

[0045] In this way, a sealing effect can be achieved between the housing unit and the basic device.

[0046] For example, the sealing element can be designed as an elastic sealing ring or a crush rib (Quetschrippe) at the housing unit.For example, the housing unit can have a sealing flange for abutting against or accommodating the sealing element.

[0047] Preferably, the housing unit has several connecting units provided on the housing unit side for reversibly connecting the housing unit to the base device.

[0048] In this way, the connection between the housing unit and the basic device can be adapted in a targeted manner.

[0049] Preferably, several connection units provided on the housing unit side are designed to be connected in a positive fit with several connection units provided on the device side and / or to be connected in a positive fit with several connection units provided on the user interface side in a connected state.

[0050] In this way, a connection of the basic device to the housing unit and / or of the basic device to the user interface can be provided particularly simply.

[0051] The medical device preferably further comprises a locking device which is designed to lock the coupling device in the connected state.

[0052] In this way, an unintentional release of the coupling device, ie an unintentional change from the connected state to the released state, can be prevented.

[0053] Preferably, the locking device has a locking actuating unit for actuating the locking device, wherein actuation of the locking actuating unit requires an actuating action that is different from an actuating action for actuating the coupling device.

[0054] In this way, it can be ensured that the locking device cannot be accidentally actuated during actuation of the coupling device.

[0055] A locking actuation unit is understood to be a unit for actuating a locking device. An actuation action is understood to be an action required by a user or operator of the medical device to actuate elements of the medical device, in particular the locking actuation unit and the coupling device.

[0056] The medical device preferably further comprises a number of additional connecting units provided on the device side for reversibly connecting the base device to the housing unit without the user interface having to be connected to the base device.

[0057] While it is preferred that the user interface and the base device accommodate the housing unit in a force-fitting and / or form-fitting manner, this is not essential. In this regard, according to the previously described preferred design of the medical device, it is also possible to connect the base device and the housing unit to each other without having to connect the user interface to the base device to establish this connection. This makes it possible, for example, to provide a subunit comprising the base device and the housing unit, and to subsequently provide the user interface. This improves the modularity of the medical device.

[0058] Preferably, the housing unit is designed as a housing cover. Furthermore, preferably, the housing unit has additional connecting units provided on the housing element side for reversibly connecting the housing unit to the basic device.

[0059] Preferably, the additional connection units provided on the housing element side are designed as a plurality of additional connection units provided on the housing element side so that when the housing unit is placed on the basic device, the plurality of additional connection units provided on the housing element side are not simultaneously engaged with the basic device.

[0060] Preferably, the user interface has a first electrical and / or signaling interface. Furthermore, preferably, the basic device has a corresponding second electrical and / or signaling interface. Furthermore, preferably, the first and second interfaces can be connected to establish an electrical and / or signaling connection.

[0061] By connecting the previously described interfaces, it is thus possible to achieve an electrical and / or signal connection between the base device and the user interface.

[0062] Preferably, the orientation of the first interface relative to the user interface and / or the orientation of the second interface relative to the base device is variable.

[0063] In this way, the orientation of the first interface and / or the second interface can be adapted to a variable orientation of the user interface relative to the base device.

[0064] Preferably, the first interface is designed as a connector which is mounted in a floating manner in or on the user interface, wherein the connector is designed to be spring-loaded in order to provide a pressing force acting on the connector in the direction of the second interface.

[0065] In this way, a secure mechanical connection between the connector and the second interface can be achieved.

[0066] The connector can be designed here as a plug or a socket, ie as a mating male or female part of the first and second interface.

[0067] Preferably, the user interface and / or the base device and / or the housing unit have a centering device so that when the user interface is placed on the base device, the first interface and the second interface are aligned with one another in at least one direction.

Figure 1 The illustrated medical device 100 may be a part of the illustrated medical device 100 or may form a separate embodiment.

[0100] exist Figure 2 Only a portion of the coupling means 9a, 9b is shown, since in accordance with Figure 1 and Figure 2 In the embodiment shown, the coupling device 9a, 9b comprises two substantially identical components 9a, 9b, so that what is said about the part 9a also applies correspondingly to the part 9b (not shown), and vice versa.

[0101] The coupling device 9a, 9b can have several locking shafts 9a3. Figure 1 In the embodiment of the present invention, these can be two locking shafts, wherein the locking shaft 9a3 is Figure 2 Shown in detail.

[0102] Each of the several locking shafts 9a3 is rotatable about a respective center axis B, so that the coupling device 9a can be manipulated, namely by rotating the locking shaft 9a3.

[0103] Preferred and also in Figure 1 and Figure 2 It is shown that the coupling devices 9a, 9b have several operating elements 91a, 91b in order to operate the coupling devices 9a, 9b, wherein the several operating elements 91a, 91b cannot be operated without tools. Figure 2 In this respect it can be seen in FIG. 1 that the actuating element 91 a of the several actuating elements 91 a , 91 b can be actuated by means of a tool 17 , such as an externally threaded hexagonal screwdriver.

[0104] The locking shaft 9a3 can be accommodated in a rotatably supported manner in a part or all of the connecting units 8a, 8b, 8c, 8d provided on the instrument side. Figure 2 In the embodiment of the present invention, the connecting unit 8a provided on the instrument side and the connecting unit 8b provided on the instrument side have corresponding bearing elements (in Figure 2 ), so that the two connecting units 8a, 8b provided on the instrument side of the medical instrument 100 can jointly accommodate the locking shaft 9a3. However, this is not necessary.

[0105] Each locking shaft can have one or more sections with grooves, wherein each groove of the locking shaft is referred to as a shaft-groove. Figure 2 In the embodiment of the present invention, the locking shaft 9a3 has a total of three shaft grooves 9a1, 9a2. In the assembled state, two shaft grooves 9a2 are accommodated in the corresponding connecting units 8a, 8b provided on the instrument side.

[0106] As in Figure 2 As can be seen in FIG, each of the several connection units 11a, 11b, 11c, 11d provided on the user interface side can be designed as a connection pin. Each of the several connection units 11a, 11b, 11c, 11d provided on the user interface side can have a connection portion-groove 11b3 (in Figure 2No reference numerals in the figure), for example, it is designed as a hollow groove.

[0107] Figures 3a to 3c The diagram shows the assembled state and the state in which the basic device 1a, the housing unit 1b and the user interface 2 are joined. Figure 2 The detailed view of is a sectional view in the following cutting plane, Figure 2 The line III-III in FIG. 1 is located in the section plane and the center axis B is perpendicular to the section plane.

[0108] exist Figures 3a to 3c , each of the several connection units 8b provided on the device side can be fastened to the basic device 1a by means of fastening means (e.g., screws 8b3). Similarly, each of the several connection units 11b provided on the user interface side can be fastened to the user interface 2, for example, to its cover plate 2a, by means of fastening means (e.g., screws 11b1). Instead of fastening with fastening means, in both cases, it is possible to provide an integral construction with the basic device 1a or the user interface 2.

[0109] The details of the present invention are Figures 3a to 3c Only one of several connection units 8b provided on the instrument side, one of the connection units 11b provided on the user interface side, and one of the connection units 1b5 provided on the housing unit side is shown, while all other corresponding units can be designed in the same or mirrored manner, thus eliminating the need for repetition.

[0110] exist Figure 3a In FIG. 1 , although the basic device 1 a , the housing unit 1 b and the user interface 2 are united via their respective connection units 8 b , 11 b and 1 b 5 , they are not yet connected because the coupling device 9 a with the locking shaft 9 a 3 has not yet been actuated to provide the connected state.

[0111] In the illustrated example, the instrument-side connection unit 8b is embodied as a hollow body and may include a sleeve 8b2 having the previously described bearing element 8b4 molded therein or thereon. The inner side of the instrument-side connection unit 8b may also include a cone 8b1. As previously described, the bearing element 8b4 accommodates the locking shaft 9a3, such that the shaft-recess 9a2 formed in the locking shaft 9a3 is arranged in the region of the user-interface-side connection unit 11b. In the coupled state, the user-interface-side connection unit 11b is aligned with the instrument-side connection unit 8b and may be configured as a pin-shaped connection pin 11b that can engage with the instrument-side connection unit 8b in a form-fitting manner. If the instrument-side connection unit 8b includes a cone 8b1 as shown, it is preferred that the user-interface-side connection unit 11b have corresponding chamfers or edges to allow for centering contact with the cone 8b1. The connection unit 11b provided on the user interface side can have a contact surface 11b5 for clamping the housing unit 1b between the basic device 1a and the user interface 2. As shown in the figure, the housing unit 1b can have, for example, a through-hole 1b5 as a connection unit 1b5 provided on the housing unit side, through which the connection unit 11b provided on the user interface side can be guided to limit the mobility of the housing unit 1b in a direction horizontal to the viewing plane. Further and / or other (e.g., form-fitting) pairings of the housing unit 1b with the user interface 2 and / or with the basic device 1a and / or with the connection unit 8b provided on the device side are possible.

[0112] feasible and in Figures 3a to 3c It is shown in FIG. 1 that each of several locking shafts 9 a 3 can have a section with a shaft-groove 9 a 2 .

[0113] As in Figures 3a to 3c As shown in , each of the plurality of locking shafts 9a3 can be designed to coordinate the shaft-groove 9a2 with the connection portion-groove 11b3 in the plurality of connection portion-groove 11b3 by rotating the locking shaft 9a3 so as to provide a released state. Figure 3a , a correspondingly realized release state is shown in , in which the user interface 2 can be removed in a vertical direction with respect to the viewing plane, since the shaft groove 9a2 is oriented towards the connection groove 11b3 .

[0114] As in Figures 3a to 3c As shown in , each of the plurality of locking shafts 9a3 may be designed so that the shaft-groove 9a2 cannot be coordinated with the connection-groove 11b3 of the plurality of connection-grooves 11b3 by rotating the locking shaft 9a3 to provide a connected state. Figure 3b In this regard, an intermediate state is shown, which can be achieved by following the Figure 3b This is achieved by rotating the lock shaft 9a3 in the rotation direction indicated by the arrow, so that the lock shaft 9a2 is partially engaged with the connection unit 11b provided on the user interface side. Figure 3c The figure shows a connected state that can be achieved by further rotation, in which the shaft groove 9a2 is not oriented toward the connecting portion groove 11b3, so that the user interface 2 cannot be removed from the basic device 1a. By establishing the locked or connected state, during the rotation of the locking shaft 9a3, the housing unit 1b is clamped between the connecting unit 8b provided on the device side and the connecting unit 11b provided on the user interface side by means of the connecting unit 1b5 provided on the housing unit side (in the example shown, by means of the through hole 1b5).

[0115] In other words, several connection units 1b5 provided on the housing unit side are designed to be connected in a form-fitting manner with several connection units 8b provided on the instrument side in the connected state, and / or to be connected in a form-fitting manner with several connection units 11b provided on the user interface side.

[0116] Depending on the rotation direction of the locking shaft 9a3, the rotation of the locking shaft 9a3 not only causes locking, but also causes the connection unit 11b provided on the user interface side to be clamped in the connection unit 8b provided on the instrument side. This advantageous effect is achieved when using Figure 3b The direction of rotation shown in the figure appears.

[0117] According to the previously described preferred embodiment of the medical device 100 according to the invention, a virtually gap-free connection is advantageously produced.

[0118] In this regard, it is particularly preferred and Figures 3a to 3c , at least one sealing element 12 is arranged between several device-side connection units 8b and some or all of the contact surfaces 11b5. This sealing element is arranged and configured to indicate prestressing by establishing a clamping-type accommodation. For example, the sealing element 12 can be arranged between some or all of the contact surfaces 11b5 and some or all of the housing unit-side connection units 1b5. It can be seen that the sealing element 12, which is essentially unprestressed in the released state, is prestressed, i.e., elastically compressed, in the connected state by clamping the several user-interface-side connection element units 11b within the several device-side connection units 8b. This allows the medical device 100 to be particularly advantageously sealed inwardly.

[0119] If the medical device 100 is designed as described above, it is preferably possible to remove or place the housing unit 1b and the operating part 2 in the released state along a common axis A, preferably along the height axis A of the basic device 1a. The common axis A or the height axis A corresponds to the height axis A in the released state. Figure 1 The axis A is shown as an example in FIG.

[0120] exist Figure 4a It is shown in Figure 1 Several operating elements 91a, 91b of the medical device 100 according to the invention are accessible from the rear side of the medical device 100. Preferably, icons 13a, 13b indicate which operating actions can be used to operate the coupling devices 9a, 9b and which state of the operating elements 91a, 91b corresponds to the released state or the connected state.

[0121] exist Figure 4b It is shown in Figure 1 The medical device 100 preferably has an openable baffle 7, which can be set up to cover several operating elements 91a, 91b in the closed state. Figure 4b In the embodiment shown in FIG, the openable flap 7 is designed as a completely removable housing element 7 .

[0122] If several connecting units 8a, 8b, 8c, 8d and coupling devices 9a, 9b are provided on the device side (e.g. Figure 1 In the case of the medical device 100, the coupling devices 9a, 9b may need different manipulation behaviors to provide the release state or the connection state, so that the coupling devices 9a, 9b are arranged in a mirror image with respect to the vertical plane or the height plane of the medical device 100. Figure 4a The icon shown in takes this situation into account.

[0123] Preferably, according to Figure 1 The medical device 100 further comprises a locking device which can be designed to lock the coupling devices 9a, 9b in the connected state. Figure 5 A corresponding embodiment with a modified connecting shaft 9a3 is shown in a perspective view in FIG. If a plurality of locking shafts 9a3 are provided, each locking shaft 9a3, 9b3 can be designed accordingly.

[0124] The locking shaft 9a3 or the operating element 91a may have a stop projection 9a4. Furthermore, the locking shaft 9a3 may have a compression spring 9a5. Furthermore, the locking shaft 9a3 may have a pin 9a7. Furthermore, the locking shaft 9a3 may have a stop ring 9a6. This stop ring may be integrally formed with the locking shaft 9a3 as part of the locking shaft 9a3, or it may be provided as a separate component on the locking shaft 9a3. For example, the stop ring 9a6 may be supported on the locking shaft 9a3 or on a bearing element 8b4 of the connecting unit 8b provided on the instrument side. However, the stop ring 9a6 may also be completely omitted.

[0125] The locking shaft 9a3, the stop ring 9a6, the compression spring 9a5 and the locking operating unit 91a with the stop protrusion 9a4 can be as shown in FIG. Figure 5 and Figures 6a to 6f As shown in FIG, the assembly is joined together using pin 9a7 by pushing compression spring 9a6 and locking actuation unit 91a onto locking shaft 9a3 and then securing them with pin 9a7, which is pressed into the elongated transverse bore in locking actuation unit 91a and locking shaft 9a3. This holds compression spring 9a5 in the preloaded position. When the basic instrument 1a is open, the assembly is simply pushed into one of the several connecting units 8a, 8b provided on the instrument side, up to the preferably provided stop, which facilitates assembly and maintenance.

[0126] Figures 6a to 6f A side view shows a partially cutaway cross-section of the previously described modified locking shaft 9a3 in the installed state. In the installed state, the stop projection 9a4 is accommodated between the locking rib 14 of the base device 1a and the locking rib 15 of the housing unit 1b. The design of the locking ribs 14, 15 and the stop projection 9a4 limits the angular range within which the locking shaft 9a3 can rotate. For example, in the illustrated embodiment, the achievable angular range is approximately 180°. Preferably, two locking states exist, allowing the locking shaft 9a3 to be locked in both the connected and released states. This can be achieved, for example, by two recesses in which the stop projection 9a4 can be locked. The recesses can be formed by the locking ribs 14, 15. To release the locking shaft 9a3 from one or more locking portions, it is preferably necessary to actuate the locking device's lock operating unit 91a, requiring a different actuation than that used to actuate the coupling device 9a. In accordance with Figures 6a to 6f In the embodiment of , this is achieved in that the compression spring 9a5 provides a preload on the locking shaft 9a3, which requires an axial displacement of the locking actuation unit 91a on the locking shaft 9a3 along the center axis B, preferably with the aid of a tool 17, in order to release the stop projection 9a4 from its corresponding recess (i.e. from the locked position) and thus allow the locking shaft 9a3 to be rotated. Figures 6a to 6f The corresponding processes are shown in sequence.

[0127] Figure 6a and Figure 6b The coupling devices 9a, 9b are shown in the released state, in which the user interface 2 and the housing unit 1b can be removed from or placed on the basic device 1a. The locking ribs 14, 15 engage the stop projection 9a4 from above and below, thereby fixing the open angular position of the locking shaft 9a3 (i.e., locking it), and thus initially preventing rotational movement.

[0128] exist Figure 6c and Figure 6d The locking process is shown in Figure 1: When actuated with the tool 17, the lock actuating unit 91a must be pressed in against the restoring force of the compression spring 9a5 and, in doing so, is guided longitudinally on the locking shaft 9a3 so that the stop projection 9a4 can clear the locking rib 15. Only in this position is rotational movement possible. Conversely, the locking rib 14 also remains engaged in this rotational plane of the stop projection 9a4, so that rotational movement of the locking shaft 9a3 is only possible within a predetermined angular range, for example, 180°.

[0129] Figure 6e and Figure 6f The locked state and the connected state in which the user interface 2 and the housing unit 1b are connected to the basic device 1a are shown. By axially unloading the locking actuation unit 91a, it is moved back to the axial starting position due to the elastic force of the compression spring 9a5, so that the locking ribs 14, 15 again engage the stop projection 9a4 from above and below. As a result, the locking shaft 9a3 is fixed (i.e., locked) in the locked position and cannot be rotated unintentionally.

[0130] exist Figure 9 A partial cross-sectional view through a height plane or vertical plane of another embodiment of the medical device 100 is shown in FIG.

[0131] exist Figure 9 As can be seen in the figure, the medical device 100 can include several additional device-side connecting units 9a1, 9b1 for reversibly connecting the base device 1a to the housing unit 1b, without having to connect the user interface 2 to the base device 1a. In the illustrated embodiment, this is achieved by at least one of the locking shafts 9a3, 9b3 (in the illustrated embodiment, each of the locking shafts 9a3, 9b3) having an additional shaft groove 9a1, 9b1. Furthermore, the illustrated embodiment shows that the housing unit 1b can include several additional housing element-side connecting units 16 for connecting to several additional device-side connecting units 9a1, 9b1. In the illustrated embodiment, the housing unit 1b includes two additional housing element-side connecting units 16 for this purpose, but this is not essential. For example, the additional housing element-side connecting units 16 can be embodied as several hooks 16 that can positively engage with several additional device-side connecting units 9a1, 9b1. The connection between the basic instrument 1a and the housing unit 1b can be achieved by placing the housing unit 1b on the basic instrument 1a and correspondingly actuating several additional connecting units 9a1, 9b1 provided on the instrument side (in the illustrated embodiment, this can be achieved by rotating several locking shafts 9a3, 9b3). This approach offers advantages for instrument logistics.

[0132] exist Figure 1 Furthermore, the figure shows that the basic device 1a has one or more projections 18 to provide a reversible connection with the housing element 1b. To this end, the housing element 1b may have several additional connecting elements 19 provided on the housing element side. For example, one or more projections 18 may be designed as multiple latches 18. For example, the multiple additional connecting elements 19 provided on the housing element side may be substantially recessed so that when the housing element 1b is placed on the basic device 1a, the multiple additional connecting elements 19 provided on the housing element side engage with the one or more projections 18. Preferably, the one or more projections 18 and / or the multiple additional connecting elements 19 provided on the housing element side, preferably recessed, are each designed with an insertion bevel to facilitate placement. It is particularly advantageous to provide multiple protrusions 18 in the form of latches, not all of which are the same length, so that not all latches 18 engage simultaneously with the multiple additional connecting elements 19 provided on the housing element side. This facilitates assembly.

[0133] exist Figure 1 As shown in FIG, it is preferred that several of the device-side connection units 8a, 8b, 8c, 8d be designed as a plurality, wherein the plurality of device-side connection units 8a, 8b, 8c, 8d are evenly distributed about a common axis A in order to provide a plurality of arrangements of the user interface 2 and / or the housing unit 1b relative to the basic device 1a. For example, in the illustrated embodiment, four orientations of the user interface 2 relative to the basic device 1a can be achieved by correspondingly rotating the user interface 2 about the common axis A. In this regard, it is preferred that each of the several user-interface-side connection units 11a, 11b, 11c, 11d is essentially configured as a pin-shaped connection pin 11b, as previously described, and that the connection pin 11b has a plurality of connection grooves 11b3 that can engage with the corresponding locking shaft 9a3 in the manner previously described, depending on the orientation of the user interface 2. The plurality of connection portions-grooves 11b3 together with the plurality of connection units 11a, 11b, 11c, 11d provided on the user interface side determine the number of possible orientations of the user interface 2 relative to the base unit 1a. Figure 7 In the embodiment shown, it is preferred that the plurality of connection portions and grooves 11b3 are evenly distributed around the central axis of the connection pin 11b, wherein two adjacent connection portions and grooves 11b3 enclose a common predetermined angle α. For example, in the embodiment shown, the common predetermined angle α is substantially 90 degrees, but it may also deviate from this angle.

[0134] Figure 8a 、 Figure 8b 、 Figure 8cThree different embodiments of the medical device 100 according to the invention are shown, which can be realized by correspondingly different arrangements of the user interface 2 and / or the housing unit 1 b relative to the basic device 1 a .

[0135] Figure 8a The medical device 100 is shown with the user interface 2 oriented in the same direction as the patient coupling part 3 .

[0136] Figure 8b The medical device 100 is shown in which the user interface 2 is arranged on the left next to the patient connection 3 in the viewing direction.

[0137] Figure 8c The medical device 100 is shown in which the user interface 2 is arranged in the viewing plane and on the right next to the patient coupling part 3. The arrangement of the user interface 2 on the left or right side of the patient coupling part 3 provides for the operating unit 2b (if present) of the user interface 2 to be arranged in a manner similar to that of the cover plate 2a (if present) according to the embodiment of the present invention. Figure 8a The arrangement offers the possibility of connection in a lower position, which enables a more compact design.

[0138] Preferred and Figure 10a and Figure 10b It is shown that an automatic electrical and / or signal connection between the user interface 2 and the basic device 1a can be achieved when the medical device 100 is assembled. For this purpose, the user interface 2 preferably has a first electrical and / or signal connection 20, wherein the basic device 1a has a corresponding second electrical and / or signal connection 21, wherein the first interface 20 and the second interface 21 can be connected to establish the electrical and / or signal connection.

[0139] In the embodiment shown, the user interface 2 or its cover 2a has a cable base 23, wherein the first interface 20 is designed as a connector, which is supported in a floating manner in or on the user interface 2 by the cable base 23 being supported in a floating manner on the cover 2a. In the embodiment shown, the second interface 21 is firmly mounted on a printed circuit board 24, which is connected to the basic device 1a. Preferably and in Figure 10a 、 Figure 10b The user interface 2 and / or the basic device 1a and / or the housing element 1b are shown to have centering devices 23a, 24a, so that when the user interface 2 is placed on the basic device 1a, the first interface 20 and the second interface 21 are aligned with each other in at least one direction. In the embodiment shown, the printed circuit board 24 has a projection 24a for this purpose, which can engage with the latch 23a of the user interface 2.

[0140] In addition, it is preferred that Figure 10a 、 Figure 10b , the connector 20 is designed to be spring-loaded in order to provide a pressing force acting on the connector 20 in the direction of the second interface 21. In the embodiment shown, this is caused by an elastic compression element 25, which can be tensioned between the cover 2a and the cable base 23.

[0141] Furthermore, it is preferred that the orientation of the first interface 20 relative to the user interface 2 and / or the orientation of the second interface 21 relative to the basic device 1a are variable. In this way, it is possible that the first interface 20 and the second interface 21 can be connected in any possible orientation of the user interface 2 relative to the basic device 1a.
