Description

[0001] The present invention relates to a medical device comprising a base unit and a cover that is removable from the base unit and pivotable to open relative to the base unit.

[0002] Covers for medical devices can serve to conceal cable and / or hose interfaces and / or other functional elements of the medical device when closed and to make them accessible to a user (clinician, service technician) when open or removed.

[0003] From DE 10 2018 005 280 B3 and EP 3 675 942 B1, a ventilator is known as an example of a medical device, which has a base unit with a cover, namely a design cover. The cover can be opened or removed by the user to provide access to cable and hose connections as well as other functional elements. DE 10 2018 005 280 B3 and EP 3 675 942 B1 describe three different ways of connecting the cover and the base unit. In a first possibility, the cover is designed as a one-way hinged door with a vertical axis. In a second possibility, the cover is designed as a one-way hinged door with a horizontal axis located near an upper edge. In a third possibility, the cover can be released and thus removed by unlocking a locking element and sliding it downwards and thus out of a positive fit formed by sectionally formed tongue and groove elements.

[0004] A disadvantage of the medical device known from DE 10 2018 005 280 B3 and EP 3 675 942 B1 is that the cover is either hinged but not removable, or removable but not hinged. This limits the user's ability to operate the cover to access components behind it. The accessibility of this medical device is therefore adversely restricted.

[0005] It is also known from the prior art to provide a cover designed as a two-part, double-hinged door. It is also known from the prior art to provide a two-part, single-hinged cover with the possibility of convex folding in the middle.

[0006] It is an object of the present invention to provide a medical device in which a cover can be actuated in a flexible manner.

[0007] These and other problems are solved by the subject matter of claim 1. The dependent claims, the description and the figures provide advantageous embodiments of the invention.

[0008] According to the invention, a medical device is provided, comprising a base unit and a cover that is removable from the base unit and pivotable relative to the base unit, wherein the cover is optionally pivotable about a first axis and / or about a second axis for opening, wherein the second axis is different from the first axis, and wherein the cover is detachable from the base unit from the first axis and from the second axis for removal.

[0009] In this way, a medical device can be provided with a cover that can be opened by pivoting it around a first axis, a second axis, or both. Additionally or alternatively, and thus optionally, the cover can be removed (detached) from the base unit. This provides the user, for example, a service technician or clinician, with several needs-based options for accessing components of the medical device behind the cover, such as cable and / or tube interfaces and / or other functional elements. Access can be gained either by opening or removing the cover, as the cover offers both possibilities. When closed, the cover can, for example, conceal an interface area of ​​the base unit. This interface area is then easily accessible by opening and / or removing the cover.to connect or remove cables and / or hoses in the interface area.

[0010] The cover can fulfill various functions, for example some or all of the following: providing a smooth and therefore easy-to-clean surface for the base unit, providing dust protection and mechanical protection for the interface area, providing a desired aesthetic design for the medical device with closed surfaces on all sides of the device.

[0011] A cover that can be detached from the first and second axes means that the cover can be detached by manual operation, i.e., without tools.

[0012] The medical device can be designed, for example, as a ventilator or as an anesthesia machine and may have corresponding assemblies and interfaces.

[0013] The base unit can serve to house electrical, electronic, mechanical, and / or pneumatic components of the medical device. The base unit can be designed as a device chassis or comprise a device chassis and other assemblies, such as attachments. If the base unit is designed as a device chassis, the cover, when closed, can, for example, conceal one side of the device chassis, such as the back. Some or all of the other sides of the device chassis can be covered by additional covers, which may be similar or different in design to the main cover.

[0014] The basic unit can essentially be cuboid in shape, for example with a square cross-section or floor plan.

[0015] For example, if the medical device is designed as a ventilator or anesthesia machine, it may have a blower for controlling and / or regulating the flow rate and / or pressure of a gas or gas mixture intended for ventilation. Furthermore, the medical device may have a gas connection for supplying ambient air and / or compressed air and / or oxygen and / or one or more other gases. The medical device may also have one or more patient interfaces, such as an inspiratory line and / or an expiratory line. The medical device may also have a control unit and / or a power supply assembly (e.g., mains connection and / or battery and / or accumulator). The medical device, particularly if designed as a ventilator or anesthesia machine, may include other pneumatic components such as lines and valves, e.g.,Proportional valves, check valves, solenoid valves and the like for influencing the gas flow from the medical device to the patient and from the patient to the environment and / or to the medical device.

[0016] The interface area can, for example, include one or more gas inlets, a power cable, a network cable, and / or one or more sensor cables. The interface area can also serve as storage space for excess cable length. For this purpose, a cable reel can be provided in the interface area.

[0017] In or on the interface area, one or more slots for one or more batteries may be provided, for example, partially or completely covered by the cover. These slots may be configured to supply the medical device with electrical power when it is disconnected from the mains. The cover can protect the slot(s) and / or the battery(ies) from unauthorized access.

[0018] The medical device may have a user interface, either as an integral component or as a component connectable to it, for inputting information by a user and / or for outputting information. For example, the user interface may include a display such as a screen to present information. For inputting information, the user interface may include an operating unit, such as input elements like knobs, buttons, rotary switches, and / or a display, in particular a touchscreen.

[0019] Preferably, the cover is designed in two parts, comprising a first cover part and a second cover part, wherein, for partial opening of the cover, the first cover part is optionally pivotable about a third axis arranged between the first axis and the second axis, and the second cover part is pivotable about the third axis.

[0020] In other words, in this preferred embodiment, the cover is not only (fully) openable and removable, but also partially openable by selectively pivoting either the first or the second cover part about the third axis, thus exposing the area of ​​the base unit located behind the respective cover part (in particular the interface area). The cover selectively provides both options for partial opening.

[0021] In this way, it is possible to open the cover only partially, depending on the requirements (optionally).

[0022] When the invention refers to "opening," it means complete opening. When the invention refers to "partial opening," it means partial opening.

[0023] Preferably, to (fully) open the cover, the first cover part is optionally pivotable about the third axis in a first step to pivot the first cover part towards the second cover part, wherein the second cover part is pivotable about the second axis in this state (i.e., in the partially open state) in a further step. Furthermore, to (fully) open the cover, the second cover part is optionally pivotable about the third axis in a first step to pivot the second cover part towards the first cover part, wherein the first cover part is pivotable about the first axis in this state (i.e., in the partially open state) in a further step.

[0024] This can improve the flexibility in handling the cover for opening and partial opening.

[0025] In other words, it is preferably possible to first pivot the first cover part towards the second cover part, thus partially opening the cover in a first step, and then pivot both cover parts together around the second axis to fully open the cover in a second step. Preferably, the first cover part locks onto the second cover part in the fully pivoted state, thus providing a particularly easy-to-handle unit.

[0026] Conversely, it is equally possible to first pivot the second cover part towards the first cover part, thus partially opening the cover in a first step, and then pivot both cover parts together around the first axis to fully open the cover in a second step. Preferably, the second cover part locks onto the first cover part in the fully pivoted position, thus providing a particularly easy-to-handle unit.

[0027] Preferably, the first axis is provided by a cover-side first coupling structure and a corresponding base unit-side first coupling structure, wherein in a connected state of cover-side first coupling structure and base unit-side first coupling structure, it is optionally possible to pivot the cover or only the first part of the cover about the first axis, wherein by releasing the cover-side first coupling structure from the base unit-side first coupling structure, it is possible to remove the cover.

[0028] This represents a particularly advantageous design of the first axis, as it allows both the pivoting function for opening and the detachability for removal to be provided by the same structure. This reduces the complexity of the medical device.

[0029] Preferably, the second axis is designed accordingly. In other words, it is preferred that the second axis is provided by a cover-side second coupling structure and a corresponding base unit-side second coupling structure, wherein, in a connected state of the cover-side second coupling structure and the base unit-side second coupling structure, it is possible to pivot the cover about the second axis, and wherein, by releasing the cover-side second coupling structure from the base unit-side second coupling structure, it is possible to remove the cover.

[0030] Preferably, the medical device further comprises a number of locking elements, wherein the number of locking elements is arranged to lock the first cover part and the second cover part together in the partially open state of the cover.

[0031] In this way, the first cover part, after pivoting around the third axis, can lock onto the second cover part and either remain secured in this position, thus providing a defined partially open state, or be pivoted around the second axis together with the second cover part as an easy-to-handle unit for (complete) opening. The same applies to the second cover part.

[0032] The number of locking elements can be singular or plural. Each locking element can, for example, be designed as a magnet.

[0033] Preferably, the first cover part and the second cover part are arranged to rest on each other in the partially open state, with the third axis being provided by a hinge opening at an angle of 180°, such as a film hinge.

[0034] Preferably, the base unit-side first coupling structure and the cover-side first coupling structure are designed to automatically lock into place when the base unit-side first coupling structure is connected to the cover-side first coupling structure.

[0035] This simplifies the handling process when inserting the cover into or onto the base unit from the state where the cover has been removed from the base unit.

[0036] Preferably, the second coupling structure on the base unit side and the second coupling structure on the cover side, if present, are configured to automatically lock into place when the second coupling structure on the base unit side is connected to the second coupling structure on the cover side.

[0037] Preferably, automatic locking is enabled by designing the first coupling structure on the base unit side and / or the second coupling structure on the base unit side as a number of spring-loaded pins by means of a spring arrangement, so that the number of spring-loaded pins can be displaced in a restoring manner in the direction of the first axis and / or the second axis.

[0038] Preferably, the medical device further comprises a handle element for opening and / or partially opening the cover, wherein the handle element for opening and / or partially opening the cover is movable from a closed state to an open state, and wherein the handle element is designed to automatically return to its original position.

[0039] This can improve the handling of the medical device.

[0040] Preferably, the cover has a retaining structure in the area of ​​the third axis which can be brought into engagement with a retaining contour of the base unit in such a way that when the first cover part and / or the second cover part is partially opened, a positive locking connection is formed between the retaining structure and the retaining contour, which causes the first cover part and / or the second cover part to lock onto the base unit.

[0041] In this way, a defined behavior can be achieved when partially opening, and a captive position of the cover can be provided when both cover parts, i.e., both the first cover part and the second cover part, are opened simultaneously.

[0042] Preferably, the first cover part and the second cover part can be of essentially the same size, with the third axis being arranged essentially centrally between the first axis and the second axis.

[0043] This allows the first cover part and the second cover part to be partially opened without the cover protruding laterally from the base unit.

[0044] Preferably, the medical device further comprises a locking mechanism that connects the base unit and the cover, wherein the locking mechanism is dimensionally stable, and wherein the locking mechanism has a hinged section, and / or wherein the locking mechanism has a spring-elastic deformable section.

[0045] When the cover is removed from the base unit, the tethering mechanism ensures that the cover remains attached. Its rigid design allows for shock absorption should the cover accidentally fall off while removed. The hinged section prevents the tethering mechanism from twisting. The spring-loaded section further enhances shock absorption, thus reducing the dynamic stress on the tethering mechanism and / or its connection to the base unit should the cover accidentally fall off.

[0046] Preferably, the first axis, the second axis, and—if present—the third axis are arranged vertically in the intended state of the medical device. Alternatively, but less preferably, the first axis, the second axis, and—if present—the third axis can be arranged horizontally in the intended state of the medical device.

[0047] Particularly preferred in a combined embodiment is a two-part cover, accessible from two sides and preferably divided vertically in the middle, which can initially be opened from both sides by approximately 180° to allow easy access to the elements of the interface area arranged on the respective side. In a second step, in this embodiment, the cover, folded to approximately 180° and thus forming a double layer, can be opened further, preferably beyond 90°, for example by approximately 130°, until the entire interface area is exposed.

Locking elements 9Ra, 9La, 9Rb, 9Lb, 10La, 10Ra, 10Lb, 10Rb can furthermore be arranged such that when a cover part 2L or 2R is opened, only this cover part 2L or 2R opens initially and the other cover part 2R or 2L initially remains in the closed position.

[0064] Some or all of the locking elements 9Rc, 9Lc can be arranged such that the two cover parts 2L, 2R are in the 180° or doubled position (see Fig. 3b, Fig. 3D Fig. 5b, Fig. 9a, Fig. 9c, Fig. 12b) to lock up.

[0065] It is in all embodiments according to Fig. 3a - 13f and 14c - 16c possible and in Fig. 9a, Fig. 9b, Fig. 9c, Fig. Figure 9d shows particularly well that, after, for example, the second cover part 2R has been opened as described, it can be moved 180° against the first cover part 2L using the central hinge 8 and locked onto it by means of the holding magnets 9Lc, 9Rc, so that the side of the interface area 3 previously covered by the second cover part 2R becomes freely accessible. In this state, it is preferred that the holding magnets 9La, 9Lb of the first cover part 2La, 9Lb are still adhered to the holding magnets 10La, 10Lb. If the entire interface area 3 is to be made accessible, the combined assembly of the first cover part 2L and the right cover part 2R can be opened further, e.g., by approximately 130°, around the first axis AL in a second step. To actuate the opening process against the force of the holding magnet pairs 9La / 10La and 9Lb / 10Lb, a handle tab 2Rd molded onto the second cover part 2R can be used.The same process is also possible from the first side; in this case, the first cover part 2L is opened as described above, so that initially only the corresponding side of the cutting area 3 is accessible. Using an optionally molded-on handle 2Ld on the first cover part 2L, the assembly of cover parts 2L and 2R can then be opened further, e.g., by approximately 130° around the second axis AR, so that the entire cutting area 3 becomes accessible again.

[0066] It is possible in all embodiments and in Fig. 6b, Fig. 7b, Fig. Figure 7c shows particularly clearly that the first axis AL and / or the second axis AR can be formed from two concentrically arranged opposing pins 11a, 11b, which can be connected to the base unit 1 and preferably have a distance between them of approximately one-third of the total height of the cover 2, 2L, 2R. In each embodiment, the cover 2, 2L, 2R can have complementary bores 2Lb, 2La, 2Ra, 2Rb into which the pins 11a, 11b can engage.

[0067] The pins 11a, 11b can be spring-mounted in the base unit 1 so that they can perform an at least approximately perpendicular movement against a corresponding spring force. In the illustrated embodiments, two pins 11a, 11b are integrated into a component via a detent element 11 mounted in the base unit 1. This component can rotate about a rotation axis C1, C2 at two bearing points 11c, 11d in the base unit 1. A spring element 12, e.g., a metallic leaf spring 12, supports a recoil effect of a spring 11e arranged centrally on the detent element 11. This mechanism causes the pairings of pins 11a, 11b and bores 2Ra, 2Rb or 2La, 2Lb to engage automatically when the cover 2, 2L, 2R is pressed against the base unit 1. Optional insertion chamfers 11a1, 11a2 may be provided on the pins 11a, 11b and / or in front of the bores 2Ra1, 2Rb1 to simplify the snap-in process.Bores 2Ra, 2Rb, 2La, 2Lb and / or pins 11a, 11b may be conical to improve the reliability of the snap-in and centering, and to allow automatic release without damage to components when disturbing forces act on the cover 2, 2L, 2R.

[0068] Opening or partially opening cover 2, 2L, 2R can cause, which is in Fig. 7d, Fig. 7e, Fig. 8a, Fig. 8b, Fig. As is particularly evident in Figure 8c, this is possible in all embodiments by a user reaching into a pocket 1aR on the base unit 1 with their hand and pulling on a handle 7 in the opening direction of the cover 2 or the respective cover part 2L, 2R. The corresponding handle 7 can be rotatably mounted on the cover 2, 2L, 2R about a handle pivot axis DR and can consequently rotate by a certain angular amount. This allows an elastic ejection element 13, which is arranged in a cavity between the inside of the handle part 7 and a sliding surface 2Rc of the cover part 2R, to be compressed and thus lengthened due to a lever geometry 13a, whereby two pins 13b, 13c on the ejection element 13 are pushed through the bores 2Ra, 2Rb and thus push the pins 11a, 11b out of the bores 2Ra, 2Rb until they no longer overlap with them, so that the cover 2 or 2Rb is opened.The respective cover part 2R can be opened.

[0069] It is possible in all embodiments and in Fig. 10, Fig. Figure 11 clearly shows that, with identical locking geometry on the left and right sides, it is theoretically possible to incorrectly position the cover 2, 2L, 2R laterally offset on the base unit 1 and still lock it into place. To prevent this incorrect operation, the pins 11a, 11b and the corresponding bores 2La, 2Lb, 2Ra, 2Rb can be made at least partially of different sizes. The pairings of pins 11a, 11b and bores 2La, 2Lb, 2Ra, 2Rb can be dimensioned such that the larger pin 11a, 11b does not fit into the smaller bore 2La, 2Lb, 2Ra, 2Rb, so that, in the event of incorrect positioning, locking occurs only at either the upper or the lower pairing of pins 11a, 11b and bore 2La, 2Lb, 2Ra, 2Rb. This means that if the cover 2, 2L, 2R is incorrectly positioned, it does not lock completely and can therefore be easily removed again. At the in Fig. 10, Fig. At the 11 points marked with an X, the locking mechanism is prevented as described in this case.

[0070] It is possible in all embodiments and in Fig. 12a, Fig. Figure 12b shows particularly clearly that the cover 2, 2L, 2R can have ventilation openings 2Le, 2Re. If the cover 2, 2L, 2R is designed in two parts, it is preferred that each cover part 2L, 2R has at least one ventilation opening 2Le, 2Re. The ventilation openings 2Le, 2Re can serve to provide a cooling air inlet for a device fan with fan housing 3f, optionally installed behind it in the interface area 3. It is preferred that identical ventilation openings 2Le, 2Re are provided in a mirror-image arrangement on the two cover parts 2L, 2R, so that in the partially open state, where both cover parts 2L, 2R lie directly on top of each other, an airflow LS can pass through both cover parts 2L, 2R unhindered.

[0071] It is in all embodiments according to Fig. 3a - 13f and 14c - 16c possible and in Fig. Figures 13a-13f clearly show that the medical device 100 can be designed such that when the handle(s) 7 are actuated to open both sides simultaneously, the holding magnet pairs 9La / 10La, 9Ra / 10Ra, 9Lb / 10Lb, 9Rb / 10Rb hold the cover parts 2L, 2R in the middle area, causing them to fold around the central hinge 8. Initially, only the force of the holding magnet pairs 9La / 10La, 9Ra / 10Ra, 9Lb / 10Lb, 9Rb / 10Rb is effective, so that the cover parts 2R, 2L are in a semi-open position, as shown in Figure 13a-13f. Fig. As shown in 13a, the magnetic force can be removed. In the example shown, this is possible up to a closing angle α of approximately 90° (see 13a). Fig. 13c). The cover parts 2R, 2L can also remain attached to the base unit 1 and be folded further. To ensure that they are firmly attached to the base unit 1 in this position and cannot fall off, a retaining contour 1b can be attached to the base unit 1 at the level of the holding magnets 10La, 10Ra (section plane of the Fig. 13c) and a holding contour 1c at the level of the holding magnets 10Lb, 10Rb (section plane of the Fig. 13d) in conjunction with retaining lugs 2Lf, 2Rf, 2Lg, 2Rg, which may be integrally formed with the cover parts 2L, 2R, are designed for a positive-locking connection from a closing angle α of approximately 90°. Once the central position is reached, the outer holding magnets 9Lc, 9Rc can hold the two cover parts 2L, 2R together, possibly supported by the holding magnet pairs 9La, 9Ra and 9Lb, 9Rb, thus creating a stable connection. The fixed central position thus achieved can be useful, for example, to open the base unit 1 during servicing without having to completely remove the cover 2L, 2R from the base unit 1. For this purpose, screw points 1e could be used, which are covered when the cover 2L, 2R is closed, but freely accessible in the central position. Such an assembly concept is described in DE 10 2024 103 650.8.

[0072] It is possible in all embodiments and in Fig. Figures 14a-14c clearly show that the medical device 100 may have a locking device 14 which connects the base unit 1 and the cover 2, 2L, 2R, wherein the locking device 14 is dimensionally stable, and wherein the locking device 14 has a hinged, in particular gimbal-type, section 14c, 14a1, 14d, and / or wherein the locking device 14 has a spring-elastic deformable section. The locking device 14 may comprise a U-shaped, pre-formed, semi-rigid retaining strap 14a, which may, for example, be made of plastic. The connection of the retaining strap 14a to the cover 2, 2L, 2R may be effected by a torsion spring 14b.If the cover 2, 2L, 2R is made in two parts, it is preferred that the torsion spring 14b is pivotally mounted on both cover parts 2L, 2R via a respective spring axis EL, ER, so that the central region 14b1 of the torsion spring is arranged symmetrically to the cover parts 2L, 2R at every closing angle α.

[0073] The articulated section 14c, 14a1, 14d may include a cardan joint. The cardan joint may comprise an eyelet with bearing pin 14c encompassing the central region 14b1 of the torsion spring 14 and a cardan connector 14d, which may be connected to the torsion spring 14 and thus to the cover 2L, 2R via a fork-shaped joint connection 14a1.

[0074] The retaining strap 14a can be pivotally mounted on the base device 1 about a pivot axis F. In a preferred embodiment, when the cover 2L, 2R is fully opened to the left or right, the retaining strap 14a stretches elastically into an approximately straight shape by means of a U-shaped section 14a2 of the retaining strap 14a deforming under spring elasticity. The length of the retaining strap 14a can be such that it is fully extended when the cover 2, 2L, 2R is fully opened, thus preventing further opening. As a further function of the retaining strap 14a, this prevents overloading of the hinge mechanism described above by excessively wide opening of the cover 2, 2L, 2R.

[0075] The dimensionally stable design of the retaining strap 14a ensures that the retaining strap 14a can move back into a defined position in the interface area 3 when closing and thus cannot come into conflict with cables, hoses or ventilation openings.

[0076] Due to its dimensionally stable design, the retaining strap 14a allows the cover 2, 2L, 2R to hang down from the base unit 1. This position can be intentionally set or accidentally, for example, if the cover 2, 2L, 2R is dropped during removal. In the latter case, in addition to the U-shaped section 14a2, an optionally angled section 14a3 and / or a cranked section 14a4 can be provided to dampen the kinetic energy of the cover 2, 2L, 2R as it falls and to influence the direction of fall of the cover 14, thereby reducing dynamic tensile stress.

[0077] The dimensionally stable design of the retaining strap 14a also allows the cover 2, 2L, 2R to be placed on top of the medical device 100. A torsional deformation of the U-shaped section 14a2 and the angular mobility between the leg spring 14b and the eyelet with bearing pin 14c, in conjunction with the gimbal connection 14c, 14d, 14a1, allow for virtually any desired position to be selected.

[0078] The cover 2, 2L, 2R of each embodiment can be mounted without tools and without additional connecting elements, as shown in particular from Fig. As can be seen in Figure 15. The locking elements 9La, 9Ra, 9Lb, 9Rb can be inserted into receptacles, e.g., pockets, of the cover 2, 2L, 2R. The central hinge 8, designed, for example, as a film hinge, can be inserted and locked into the cover parts 2L, 2R, e.g., by means of molded locking hooks 8a, e.g., by inserting it laterally into corresponding grooves, thereby fixing the locking elements 9La, 9Ra, 9Lb, 9Rb in the receptacles. The ejection elements 13 can be inserted from the inside through the bores 2Ra1, 2Rb1 or 2La1, 2Lb1 and locked to the cover parts 2L or 2R. The locking elements 9Lc or 9Rc can be inserted into the cover parts 2L, 2R. The handle part(s) 7 can be locked to the cover parts 2L or 2R from the outside, thereby holding, i.e. fixing, the ejection elements 13 and the locking elements 9Lc or 9Rc.The optional torsion spring 14b of the optional retention device 14 can be bent open and inserted vertically from above or below into corresponding vertical bores on the cover parts 2L, 2R, thus providing movement about the described spring axes EL and ER. The eyelet with bearing pin 14c can, for example, be split horizontally in the middle and, with slight bending, one half can be threaded through the middle section of the torsion spring 14b1. The cardan connector 14d can be inserted into the fork-shaped joint 14a1 of the retaining strap 14a and then locked into place with the eyelet. Finally, an optional holding magnet 15a can be snapped into a corresponding receptacle in the retaining strap 14a from below. This results in a stable connection of all retaining strap parts 14a-14d, 15a. This is possible in all embodiments and in . Fig. Figures 16a - 16c show that the cover 2, 2L, 2R can have auxiliary graphics 2Lj, 2Rj, 2Lk, 2Rk, 2Lm, 2Rm, 2Ld1, 2Rd1.

[0079] The auxiliary graphics 2Lj, 2Rj, 2Lk, 2Rk, 2Lm, 2Rm, 2Ld1, 2Rd1 can be arranged on the outside and / or inside of the cover 2, 2L, 2R and provide instructions for operating the cover 2, 2L, 2R and / or instructions for elements of the interface area 3.

[0080] In the exemplary embodiment according to Fig.Figures 16a-16c depict graphics 2Lj and 2Rj on the outer surface (i.e., the side facing outwards when closed) of the cover parts 2L and 2R, respectively. These graphics illustrate the operation for opening the first and second cover parts 2L and 2R. Below these graphics may be symbolic representations 2Lk and 2Rk of interface elements located under the respective cover part 2L or 2R. Thus, it is immediately apparent from the outside which cover part 2L or 2R must be opened to access the desired interface element. In the exemplary embodiment, the sensor connections, USB connection, network connection, and a first battery are symbolized in the figure 2Lk, while the O2 and AIR gas connections and a second battery are symbolized in the figure 2Rk. If a cover part 2L or 2R, for example,When the second 2R is opened 180°, a color marking 2Rd1 on the then visible handle 2Rd and a further marking 2Rm can guide the complete opening process. Corresponding elements 2Ld1, 2Lm can become visible on the first cover part 2L when it is opened accordingly.
