[0020] In contrast, the object of the present invention is to improve the use of respiratory therapy devices and, in particular, to make their use and operation more comfortable even in confined spaces. Specifically, the use of two respiratory therapy devices, for example for ventilation and cough support, is also to be made more convenient.

[0021] This problem is solved according to the invention with the respiratory therapy device of claim 1, as well as with the system of claim 23 and with the system of claim 24. Further developments and advantageous embodiments are the subject of the dependent claims. Further advantages and features will become apparent from the general description and the description of the exemplary embodiments.

[0022] The respiratory therapy device according to the invention serves to generate a flow of air for the purpose of respiratory therapy. The respiratory therapy device comprises at least one housing for enclosing device components. This housing comprises at least two mounting surfaces. This allows the respiratory therapy device to be set up and preferably operated in at least two positions as intended. In particular, the respiratory therapy device is operated as intended in these at least two mounting positions. The respiratory therapy device according to the invention offers many advantages. A significant advantage is the housing with its mounting surfaces, which allows the respiratory therapy device to be set up and operated in different positions. This enables the selection of the optimal mounting position depending on the available space and environmental conditions.For example, a different setup position can be implemented quickly and easily for a person lying down compared to a person standing.

[0023] Preferably, the housing assembly comprises at least one first mounting surface for at least one first mounting position. Preferably, the housing assembly comprises at least one second mounting surface for at least one second mounting position. In particular, at least one mounting surface is provided for each mounting position. The first mounting surface is preferably suitable and designed for a horizontal mounting position. The second mounting surface is preferably suitable and designed for a vertical mounting position. In the horizontal mounting position, the respiratory therapy device rests, in particular, on the first mounting surface. In the vertical mounting position, the respiratory therapy device stands, in particular, on the second mounting surface.

[0024] Such designs allow for a particularly easy and convenient switch between using the respiratory therapy device in a lying and standing position. Depending on accessibility requirements, the device's location, and the user's position, it can be used either upright or lying down. To change positions, the device simply needs to be repositioned, for example, by tilting it from a standing to a lying position or vice versa. This allows the user to easily adapt the device to their needs by adjusting its position by raising or tilting it.

[0025] In the horizontal position, the height of the respiratory therapy device is typically less than the length and / or width of the first surface it is placed on. In the vertical position, the height of the respiratory therapy device is typically greater than the length and / or width of the second surface it is placed on. This allows for optimal adjustment of the device's accessibility and space requirements by selecting the appropriate position.

[0026] In the horizontal position, the installation height corresponds in particular to the length and / or width of the second installation surface. In the vertical position, the installation height corresponds in particular to the length and / or width of the first installation surface. In particular, the first installation surface is longer and / or wider than the second installation surface. In particular, the first and second installation surfaces are of the same width. It is also possible that the first and second installation surfaces are of the same length. In particular, the installation surfaces correspond to the footprint of the respiratory therapy device in the installation position on the respective installation surface.

[0027] The horizontal position is defined in particular by the fact that the maximum and / or mean height of the respiratory therapy device, especially its housing, is less than the maximum and / or mean length and / or maximum and / or mean width of the respiratory therapy device, especially its housing. In the horizontal position, the maximum and / or mean height of the respiratory therapy device, especially its housing, is less than the maximum and / or mean length and / or maximum and / or mean width of the first surface on which the respiratory therapy device is placed in the horizontal position.

[0028] The upright position is defined in particular by the fact that the maximum and / or mean height of the respiratory therapy device, especially its housing, is greater than the maximum and / or mean length and / or maximum and / or mean width of the respiratory therapy device, especially its housing. In the upright position, the maximum and / or mean height of the respiratory therapy device, especially its housing, is greater than the maximum and / or mean length and / or maximum and / or mean width of the second surface on which the respiratory therapy device is placed.

[0029] In particular, the mounting surfaces are arranged at an angle of at least 65° and at most 115°, and preferably at an angle of at least 80° and at most 100°, and especially preferably at an angle of 90° + / -5° to each other.

[0030] It is also preferred that the mounting surfaces are arranged at right angles to each other. In particular, the first mounting surface is arranged at one of the previously described angles to the second mounting surface. In such a configuration, the advantages of the different mounting positions are particularly well utilized. Other angles between the mounting surfaces are also possible.

[0031] According to the invention, the center of gravity of the respiratory therapy device is arranged in a lower half of the device, preferably in a lower quarter, and particularly preferably in a lower eighth, at least in the one of the at least two setup positions as described above in which the respiratory therapy device has a greater height. In particular, the center of gravity is arranged in this way at least in the upright setup position. Specifically, the center of gravity is arranged in this way in the setup position that has a smaller footprint than the other setup position. It is also possible that the center of gravity is arranged in this way in all intended setup positions. In particular, the center of gravity is arranged closer to the second footprint than to an upper end of the device, at least in the upright setup position.This reliably prevents the device from accidentally tipping over.

[0032] According to the invention, the device's center of gravity is provided at least by the arrangement of at least one battery unit for powering the respiratory therapy device and / or by the arrangement of at least one fan unit for generating a respiratory gas flow. The device's center of gravity can also be provided by the arrangement of at least one other heavy device component. Such configurations favor a low center of gravity, particularly in the upright position. The battery unit serves in particular to provide power during ventilation and / or a coughing maneuver and specifically provides the energy for respiratory therapy.

[0033] The respiratory therapy device includes, in particular, at least one interface for connecting hoses for respiratory gas flow and, for example, a breathing tube and / or cough tube. The respiratory therapy device also includes, in particular, at least one cable connection for an electrical power supply and / or for network connection or the like. The interface and / or cable connection may also be designed for connecting accessories suitable for the respiratory therapy device. The interface and / or cable connection are preferably located in at least one of the at least two installation positions in a lower half of the device in which the respiratory therapy device has a greater height. In particular, the interface and / or cable connection are located in a lower quarter and, more preferably, in a lower eighth of the device.Such an arrangement of the interface and / or cable connection is provided, in particular, in the upright position. Such an arrangement of the interface and / or cable connection may also be provided in both upright positions. Specifically, at least in the upright position, the interface and / or cable connection are located closer to the second support surface than to an upper end of the device. This reliably prevents excessive torque from being generated in the event of accidental pulling on a hose or cable, which could cause the device to tip over.

[0034] The interface and / or cable connection are preferably located laterally on the housing in all intended installation positions. In particular, the interface and cable connection are positioned laterally to the installation surfaces in all intended installation positions, preferably at least in the upright position. This effectively prevents the housing from tipping over due to accidental pulling.

[0035] The respiratory therapy device includes, in particular, at least one handle. The handle is used, in particular, for carrying and / or changing the device's position. Specifically, the handle is arranged such that, in a horizontal position, it is located on the front of the housing, and in an upright position, it is located on the top of the housing. This ensures that the handle is accessible to a person standing in front of the respiratory therapy device in both positions. Specifically, the handle is accessible from the same user position in both positions. In particular, the handle is positioned at a distance from the surface on which the respiratory therapy device is placed in both positions. This allows the handle to be gripped or grasped in all positions.The handle is designed to be easily gripped and / or at least graspable in all intended installation positions.

[0036] The handle is preferably recessed on the housing. This means the handle does not protrude from the contour of the housing. In particular, the handle is integrated into the housing, for example, by being recessed. This ensures the handle does not obstruct any installation position. Alternatively, the handle can be attached to the housing in a protruding position.

[0037] The handle is preferably fixed to the housing. In particular, the handle is rigidly designed. This design has the advantage that the device can be moved and its position changed without having to first position the handle and, for example, fold it out. Furthermore, such a handle allows for easy and ergonomic carrying of the device as well as quick changes from a horizontal to a vertical position and vice versa. However, it is also possible for the handle to be foldable, extendable, tiltable, swiveling, or movable.

[0038] The housing assembly includes, in particular, at least one housing edge, which is designed as a tilting edge or includes at least one such edge. The housing assembly is tilted, in particular, via the tilting edge to change between the installation positions. The tilting edge is preferably flexible and / or reinforced, and in particular abrasion-resistant and / or rounded. It is also possible that the tilting edge is replaceable and / or hardened. It is possible that the tilting edge includes at least one protective element. The protective element is in particular soft and / or elastic and / or flexible, or also hardened and / or replaceable. Such a design has the advantage that the device can be tilted without having to be completely lifted. In addition, such a tilting edge allows the tilting process to be carried out more easily.The device can be moved without causing scratches to the device or the surface it's placed on, or without the user having to worry about such damage. The tipping edge extends specifically between the two surfaces. In particular, the two surfaces converge or meet at the tipping edge.

[0039] Such designs can also be provided for the installation surfaces, at least in certain areas, to prevent wear and tear or damage. It is possible that the installation surfaces are at least partially flexible and / or reinforced, and in particular abrasion-resistant and / or equipped with at least one protective element.

[0040] In particular, the handle is positioned opposite the tipping edge. This creates a sufficiently large lever, making it especially easy to tilt the device to change its position.

[0041] The mounting surfaces are provided, in particular, by at least one side surface of the housing. Specifically, the mounting surfaces are provided by an entire side surface. This offers particularly large mounting surfaces, resulting in exceptionally reliable tilt stability. It is also possible that the mounting surfaces comprise at least 75%, and in particular at least 85%, and preferably at least 90%, and most preferably at least 95% of the respective side surface. The side surface is, in particular, an outer surface. A side surface is understood to be, in particular, a front, top, bottom, back, right side, and / or left side.

[0042] The respiratory therapy device is particularly preferably designed and configured to be moved between positions simply by setting up and preferably tilting the housing, and especially without any further measures. In particular, no adjustments to the housing and / or the handle are necessary. Specifically, no coupling, adjustment, or modification of components on the respiratory therapy device is required to move it between positions. Specifically, no hoses, cables, or the like need to be reconnected. Specifically, the respiratory therapy device can be moved between positions without having to lift the entire device. Specifically, the respiratory therapy device can be moved between positions simply by tilting or pivoting, especially over the tilting edge.This offers a particularly convenient adjustment of the setup position.

[0043] It may be designed so that respiratory therapy during operation, such as ventilation and / or cough support, can be transferred between setup positions without further measures. In particular, the therapy does not need to be interrupted. It is also possible that a therapy pause is set automatically or manually for the transfer between setup positions.

[0044] In a particularly advantageous embodiment, the respiratory therapy device is suitable and configured to automatically detect its current position by means of at least one control unit. Specifically, the respiratory therapy device is suitable and configured to modify and / or monitor at least one device setting based on its position, using the control unit. It is possible that the control unit for detecting the position is associated with at least one sensor. Additionally or alternatively, the control unit can output at least one user message based on the position, for example, a message indicating a necessary manual adjustment of a device setting. The device setting can include device components of the respiratory therapy device and / or therapy settings for ventilation or cough therapy.

[0045] The respiratory therapy device is particularly preferably designed and configured to automatically adjust at least one display mode and / or at least one function assignment of an operating device, depending on its position, via the control unit. This automatic adjustment of the display or operation further enhances the device's flexibility in terms of placement.

[0047] The display and / or control unit is preferably arranged on at least one side surface of the housing and, in particular, integrated. This side surface is preferably the largest side surface of the housing. It is also possible and preferred that the display and / or control unit is arranged on at least one side surface of the housing that has a larger area than the individual surfaces of the mounting bases. This allows the information on the display to be read particularly well and presented clearly.

[0072] Further advantages and features of the present invention will become apparent from the description of the exemplary embodiments, which are explained below with reference to the accompanying figures.

[0073] The figures show: Fig. 1 a purely schematic representation of a system according to the invention with a coupling device with two respiratory therapy devices according to the invention in a perspective view; Fig. 2 the system of Fig. 1 in a rear view; Fig. 3 a respiratory therapy device according to the invention in a perspective view; Fig. 4 a coupling device in a perspective view; Fig. 5 the coupling device of the Fig. 4 in a view from a low angle; Fig. 6 a perspective detail view of the coupling device of the Fig. 4 in a view from an oblique top view; Fig. 7 another perspective detail view of the coupling device of the Fig. 4 in a view from an oblique angle above; and Fig. 8 a perspective detail view of the coupling device of the Fig. 4 in a view from a low angle.

[0074] The Figure 1Figure 1 shows two respiratory therapy devices 1 according to the invention, which are coupled here via a coupling device 200 according to the invention to form a system 300. Such a system 300 offers a particularly user-friendly and space-saving arrangement of two respiratory therapy devices 1. The respiratory therapy devices 1 can also be used individually or stand-alone without the coupling device 200. A single respiratory therapy device 1 according to the invention is in the Figure 8 shown.

[0075] One respiratory therapy device 1 is configured here as a ventilator 20 and the other as a cough device 10. The ventilator 20 includes a fan 102, which is not visible inside, to generate an airflow for ventilating the patient. The cough device 10 serves to specifically support the clearing of secretions from the patient's airways and uses the fan 102 for insufflation and exsufflation.

[0076] The internal components of the respiratory therapy device 1 are enclosed by a housing 2. The housing 2 comprises several surfaces: a front 32, a top 42, a bottom 52, a back 62, and two side panels 72 and 82. The device 1 is a portable respiratory therapy device with a maximum weight of 6 kg.

[0077] Furthermore, the respiratory therapy device 1 comprises a display unit 7 and a control unit 17. Part of the control unit 17 is provided by a touch-sensitive surface of the display unit 7. The control unit 17 also includes various hard keys, such as buttons and switches.

[0078] The respiratory therapy device 1 can be set up and operated in two different positions 3 and 4. The lower respiratory therapy device 1 of the system 300 is shown here in a horizontal position 3, and the upper respiratory therapy device 1 in a vertical position 4. To enable these positions 3 and 4, the housing 2 includes two support surfaces 12 and 22. A first support surface 12 is for the horizontal position 3, and a second support surface 22 is for the vertical position 4.

[0079] For the horizontal device 1, the first support surface corresponds to the underside 52 and the second support surface 22 to the rear 62. For the vertical device 1, the first support surface 12 corresponds to the rear 62 and the second support surface 22 to the underside 52.

[0080] To move the individual respiratory therapy device 1 from the horizontal to the vertical position 3, 4, or vice versa, without the coupling device 200, it simply needs to be tilted. Changing between positions 3, 4 is possible without any further measures, such as coupling or folding elements. This is achieved, among other things, by the sufficiently large footprints 12, 22 and the fact that the device's center of gravity is sufficiently low, even in the vertical position. Furthermore, no reconnecting of hoses or cables is necessary for changing the position. The respiratory therapy device 1 can also provide the required airflow for the respective therapy regardless of the position 3, 4. In addition, the air intake openings are arranged in such a way that reliable air intake is ensured in all positions 3, 4, and there is no risk of blockage.The openings necessary for suction, as well as all other openings of the housing assembly 2, correspond to protection class IP22.

[0081] The device's center of gravity is located in the lower half of the device in the upright position 4. A battery unit 101 for power supply and a fan unit 102 are also located in this lower half. Furthermore, the interface 103 for connecting ventilation tubing and the cable connections 104 are located in the lower half of the device. This ensures that the device 1 remains stable in the corresponding upright position 3 even if a tube or cable is accidentally pulled. 4. The interfaces 103 and the cable connections 104 were also arranged so that they are located laterally on the housing unit 2 in all installation positions 3, 4.

[0082] To facilitate the simplest and most comfortable transition between the two positions 3 and 4, an integrated handle 5 is provided, recessed into the housing 2. This ensures that the handle 5 does not protrude from the contour of the housing 2. Furthermore, the handle is designed and positioned so that it can be gripped in both positions 3 and 4. The handle 5 is also rigid and therefore does not need to be folded or extended before changing the position 3 or 4. Thus, the handle 5 allows for easy and ergonomic carrying of the device 1 as well as quick changes from the horizontal to the vertical position 3 or 4, and vice versa. Additionally, the handle 5 is easily accessible to a user standing in front of the respiratory therapy device 1 in both positions 3 and 4.

[0083] To further simplify the setup and placement of the device 1, the housing 2 is equipped with a tilting edge 6. This allows the device 1 to be tilted over its lower or rear edge for repositioning without the user having to fully move the device 1. The tilting edge 6 is preferably provided with suitable protective, soft, or flexible support elements on the two support surfaces 12 and 22. These elements allow the tilting and repositioning process to occur without causing scratches to the device or the support surfaces 12 and 22, or without the user having to worry about such scratches.

[0084] The respiratory therapy device 1 includes a control unit 105, which automatically detects the respective setup position 3, 4, for example by means of a sensor device and e.g.This then changes a device setting. For example, depending on the setup position 3, 4, the orientation of the touchscreen is rotated or mirrored accordingly.

[0085] The display unit 7 has a display area that essentially covers the entire surface of the largest side of the device 1. In the horizontal position 3, this corresponds to the top 42, and in the vertical position 4, to the front 32. The viewing angle of the display unit 7 is optimized for a standing person in the horizontal position 3. In the vertical position 4, the viewing angle is optimized accordingly for a lying or sitting person. The respiratory therapy devices 1 shown here can also be set up and operated in a back-to-back arrangement without the coupling device 2. For this purpose, both devices 1 are set up in the vertical position 4 so that they rest on the second support surfaces 22. The first support surfaces 12, i.e., the rear sides 62, then touch each other, so that the devices can always support each other or in the event of a collision.

[0086] The coupling device 200 enables a mechanical and reliable connection of the two respiratory therapy devices. 1. For this purpose, the lying respiratory therapy device 1 is connected to a coupling element via a first coupling unit 201, and the standing respiratory therapy device 1 is connected to a coupling element via a second coupling unit 202. The coupling element 205 is designed here as a tubular element and, for example, as a square tube.

[0087] In one embodiment, a chassis 207, shown here in a highly schematic form, can be mounted to the coupling element 205. This allows the entire system 300 to be moved particularly easily and handled flexibly. For gripping the system 300, an additional handle 206 is provided, which in the embodiment shown here is located in the area of ​​the reclining respiratory therapy device 1.

[0088] The coupling device 200 or the system 300 are described below with reference to the Figure 1and the detailed representations of the Figures 2 to 7 described.

[0089] The coupling units 201 and 202 each comprise a coupling blade 203 and a coupling plate 204. The coupling blades 203 are attached to the coupling element 205. The connection between the coupling blade 203 and the coupling plate 204 is shown in the Figure 2 This connection for the upper device 1 is particularly easy to see in a rear view of the system 300. The coupling plates 204 are attached here as accessories to the first mounting surfaces 12 of the housing assemblies 2 of the respective respiratory therapy devices 1. The devices 1 are attached to the coupling element 205 by inserting the coupling blade 203 into the coupling plate 204. Tool-free release and attachment are preferably provided. A locking mechanism, for example a latch, can also be provided. Here, for example, a locking element 208 is provided, which is located in the Figure 7which is particularly easy to see.

[0090] The coupling blade 203 for the lower or horizontal device 1 is attached here to a projection 215 extending from one longitudinal side of the coupling element. The projection 215 is in the Figures 3 and 4 This is particularly evident in those where the coupling device 300 is shown without respiratory therapy devices 1.

[0091] The belt buckle 203 for the upper device 1 is, as in the Figure 2 This is particularly easy to see, mounted on the coupling element 205. The coupling blade for the lower device 1 is, as shown in the Figure 3 Particularly easy to see, it is arranged on a mounting plate 213. The coupling blade 203 is then mounted on the extension 215 via the mounting plate 213.

[0092] In the Figures 5 to 7 The mounting plate 213 with the coupling blade 203 and the additional handle 206 of the coupling device 200 is shown from various views. The mounting plate 213 of the Figure 6in the Figure 7 equipped with a coupling plate 204, so that the connection between coupling blade 203 and coupling plate 204 is particularly easy to see. The coupling plate 204 can be part of the coupling device 200 or an accessory or fixed part of the housing 2 of the respiratory therapy device 1. For example, the coupling plate 204 can be screwed into the housing 2. Alternatively, the coupling plate 204 can also be designed as a corresponding recess in the housing 2 into which the coupling blade 203 can be inserted. Corresponding designs are also available for the [unclear - possibly "devices" or "components"]. Figure 2 The coupling plate 204 shown is provided for the upper respiratory therapy device 1.

[0093] In the Figure 7The underside of the mounting plate 213 is shown, so that a connecting device 217 is particularly easy to see. The connecting device 217 can be used to connect coupling plate 204 and coupling blade 203, or it can be used to connect to a chassis 207.

[0094] The Figure 8 Figure 1 shows a single respiratory therapy device 1 in a horizontal position 3. The device 1 is still equipped with a coupling plate and an additional handle 206, which, however, belong to the previously described coupling device 200 and are not part of the respiratory therapy device 1 shown here. The device 1 shown here can be easily and conveniently transferred to the upright position 4 by tilting it around the tilting edge 6.

[0095] In one embodiment, the coupling device 200 can have a mounting plate 213 for a respiratory therapy device 1, wherein the coupling device 200 and the mounting plate 213 are mounted on a chassis 207. The mounting plate 213 has at least one connecting device 217, which can be configured as a (paired) rail system, wherein the connecting device 217 is designed and configured to interact with a corresponding receptacle on the respiratory therapy device 1 in a force-fit or form-fit manner. The respiratory therapy device has receptacles in the area of ​​its mounting surface that interact with the rail system in a force-fit or form-fit manner.The respiratory therapy device can be placed on the mounting plate with its base and slid into a setup position on the mounting plate, whereby the respiratory therapy device moves at least section by section along the rails until the rails interact with the receptacles (force-fit or form-fit). A locking element 208 in the area of ​​the mounting plate serves to secure the respiratory therapy device 1 to the mounting plate in the setup position. The mounting plate is preferably arranged horizontally on a chassis, the chassis being able to extend vertically relative to the mounting plate. The mounting plate has the rails as its left and right boundaries, in the form of a raised section, and a further rail or edge or a section of the chassis as its rear boundary.The front area of ​​the mounting plate has no limit and serves to place the respiratory therapy device 1 here and slide it onto the mounting plate.

[0096] The connecting device 217 and the corresponding receptacle on the respiratory therapy device 1 are preferably designed and configured such that both align with each other or slide along each other when the respiratory therapy device is placed on the mounting plate with its base and slid into a standing position on the mounting plate. For this purpose, the rails are preferably arranged in a funnel shape on the horizontally arranged mounting plate, with the opening of the funnel at the front and the funnel narrowing towards the rear. The respiratory therapy device can then be locked onto the mounting plate by means of a locking element 208. Reference symbol list:
