METHOD AND DEVICE FOR OPERATING VENTILATORS

Description

[0001] The invention relates to an operating device for a ventilator.

[0002] Ventilators typically have separate operating and information or display elements. Operating elements are implemented, for example, as switches or rotary knobs. The settings made via these controls can then be read on separate displays. This results in complex operation for the user with unintuitive menu navigation.

[0003] US 6 158 432 A describes a ventilator with a touch-sensitive screen on which numerical values ​​can be displayed numerically and graphically.

[0004] EP 2 564 887 A2 describes a ventilator with a touch-sensitive screen on which the shape of curves of ventilation parameters can be adjusted by touching and dragging with a finger.

[0005] The online article "HTML 5 RANGE tag" provides an example of how sliders for setting numerical values ​​can be coded in HTML (Parks: "HTML 5 RANGE tag", February 10, 2014, XP055758421; URL: https: / / web.archive.org / web / 20140322022659 / https: / / www.bauer.uh.edu / parks / slider.htm [accessed December 9, 2020]).

[0006] The object of the present invention is therefore to provide a user-friendly and intuitively operable control device for a ventilator. In particular, the user should be able to quickly make important settings without having to navigate through deep, nested menu structures.

[0007] The problem is solved by the features of the main claim.

[0008] The invention relates to an operating device for a ventilator. The operating device comprises: a touch-sensitive graphic display that at least temporarily represents the value range for a ventilation parameter and displays at least individual values ​​numerically; a memory for ventilation parameter values; at least one data point associated with the value range; at least one position of the touch-sensitive graphic display logically connected to the data point; switching logic that, upon touching the position of the touch-sensitive graphic display logically assigned to the data point, causes the display of at least one numerical value assigned to the data point and / or a confirmation field for the numerical value; switching logic that, upon touching the numerical value or the confirmation field, applies this numerical value to the assigned respiratory gas parameter and writes it to the memory along with the assigned respiratory gas parameter.

[0009] According to the invention, in addition to the touch-sensitive display, only one further control element is provided. This control element is mechanically operated and thus differs from the touch areas on the display. According to the invention, the ventilator is switched on and off via this control element, so that basic, patient-specific therapy can be activated with just one button. For this purpose, the control element is logically connected to the blower motor and activates it as well as the memory to retrieve and apply stored therapy data, such as pressure values. Additionally, individual values, such as pressure values, can be adjusted via the input buttons of the touch-sensitive display. However, according to the invention, operation via the input buttons of the touchscreen is not necessary to start the therapy.

[0010] The invention relates to an operating device for a ventilator with a touch-sensitive graphic display and only one further mechanical control element, wherein the basic therapy can be started by pressing down the mechanical control element and additional settings are made via a touch-sensitive graphic display.

[0011] According to the invention, the finger position is also detected as soon as the user approaches the screen. The operating logic would be similar to that described above, but touching the screen would then, for example, confirm the set value.

[0012] The operating device is also designed so that the ventilation parameter is pressure or flow or volume or frequency or IPAP or EPAP or PEEP or FiO2.

[0013] The operating device is also designed in such a way that the control panel is in the form of a number line or bar and the entire range of values ​​is visualized on the display in the form of a number line or bar.

[0014] The operating device is also designed in such a way that the visualized number line also serves as a control panel.

[0015] The operating device is also designed so that the control panel is touch-sensitive across the entire visualized setting range.

[0016] The operating device is also designed so that the desired value can be selected with just one touch of the desired area.

[0017] The operating device is also designed so that the detected value is visualized in an additional field.

[0018] The operating device is also designed so that the detected value can additionally be accessed via the + / - symbols for fine adjustment.

[0019] The operating device is also designed in such a way that the memory stores at least the last entered and applied value as well as the chronologically preceding value, and in the event of an activation of the undo function, the memory always outputs the chronologically most recent value first.

[0020] The operating device is also designed such that at least one collection of ventilation parameters stored in the memory comprises at least three preset parameters, selected from pressure or flow or volume or frequency or I-PAP or EPAP or PEEP or FiO2, and an area is provided in the touch-sensitive graphic display for this collection of ventilation parameters, in which the collection of ventilation parameters is graphically represented, and at least one data point associated with the collection of ventilation parameters, at least one location of the touch-sensitive graphic display logically connected to the data point, a switching logic which, when the location of the touch-sensitive graphic display logically assigned to the data point is touched, causes a display of at least one collection of ventilation parameters assigned to the data point and / or a confirmation field for the collection of ventilation parameters, a switching logic,which, upon touching the numerical value or the collection of ventilation parameters, applies this collection of ventilation parameters.

[0021] The operating device is also designed so that the control unit registers changes in current, resistance, or voltage in the area of ​​the humidifier's heating element and thus detects a falling or low water level based on an increased current, resistance, or voltage value of the heating element, and this causes the control unit to display a symbol or text message in the display area that symbolizes or names a low water level.

[0022] The operating device is also designed in such a way that the operating system includes a graphical setting aid for at least one ramp gradient.

[0023] The operating device is also designed to include a graphical setting aid for trigger sensitivity.

[0024] The operating device is also designed such that at least one adjustment element is designed as a rotary knob.

[0025] The operating device is also designed in such a way that at least one circular display element is used.

[0026] The operating device is also designed to use a rotary push button.

[0027] The operating device is also designed to use a start-stop control surface.

[0028] The operating device is also designed so that the start-stop control surface is located in the area of ​​the touchscreen.

[0029] The operating device is also designed in such a way that the start-stop control surface can be generated by a device controller in different designs.

[0030] The operating device is also designed so that individual values ​​of a ventilation parameter are displayed numerically, and the selected value is also displayed numerically, and a graphical visualization of the selected ventilation parameter is also provided.

[0031] The operating device is also designed in such a way that three fixed levels are provided for the ventilation parameter and these levels can be adjusted using the + / - symbols in order to fine-tune the ventilation parameter to the individual patient.

[0032] The operating device for a ventilator comprises: a graphic display that at least temporarily represents the value range for a ventilation parameter and displays at least individual values ​​numerically; a memory for ventilation parameter values; at least one data point associated with the value range; at least one position of the graphic display logically connected to the data point; a switching logic that, when the position of the mechanical control element logically assigned to the data point is actuated, causes a display of at least one numerical value assigned to the data point and / or a confirmation field for the numerical value; a switching logic that, when the position of the mechanical control element logically assigned to the data point is actuated, applies this numerical value to the assigned respiratory gas parameter and writes it to the memory along with the assigned respiratory gas parameter.

[0033] The operating device is also designed in such a way that the change in values ​​during the setting process via the mechanical operating element and / or the selected value and / or the available value range is / are visualized on the graphic display element.

[0034] The operating device for a ventilator, preferably for a CPAP, APAP, Bilevel or home therapy ventilator, is equipped with a display for showing information and for showing control panels for the user and at least one touch-sensitive input field.

[0035] In The drawings schematically illustrate exemplary embodiments of the invention. They show: Fig. 1 a perspective view of a ventilator with breathing mask and breathing gas tube, Fig. 2 a display of an operating and information system, Fig. 3 a display to illustrate a submenu, Fig. 4 a control panel in the form of a number line, Fig. 5a, 5b control panel in the form of a graphic, Fig. 6a, 6b representation similar to in Fig. 5 To illustrate another operating state, Fig. 7a; another control panel in the form of a graphic, Fig. 7a; setting a pressure waveform, Fig. 7c; a variant of Fig. 7b Fig. 8 a schematic representation of a graphical setting aid for ramp steepness, Fig. 9 a schematic representation of a graphical setting aid for trigger sensitivity, Fig. 10 a graphical setting aid for at least one pressure, Fig. 11 a supplementary representation to the Figuren 7a, 7b , Fig. 12 an illustration to demonstrate the ratio of inspiratory time to total tidal time, Fig. 13 a schematic representation of a circular control element, Fig. 14 an alternative embodiment and Fig. 15 a mechanical control element.

[0036] Fig. 1 Figure 1 shows the basic structure of a ventilation device. Within the housing 1 of a ventilator 20, which contains a breathing gas source, a control element 2 and an operating and information system 3 are arranged. The system consists of a display 13 and a touch-sensitive input unit 15 with at least one control panel 14. A connecting hose 5 is attached via a coupling 4. An additional pressure measuring hose 6 can run along the connecting hose 5 and can be connected to the housing 1 via a pressure inlet port 7. The housing 1 has at least one interface 8 to enable data transmission. A humidifier can also be attached.

[0037] An exhalation element 9 is arranged in the area of ​​an extension of the connecting hose 5 facing away from the device housing 1. An exhalation valve can also be used.

[0038] Fig. 1 Furthermore, a patient interface designed as a ventilation mask 10, which is implemented as a nasal mask, is shown. Fixation to the patient's head can be achieved using a head hood 11. In the area of ​​its extension facing the connecting tube 5, the patient interface 10 has a coupling element 12.

[0039] Interface 8 allows for the input and / or output of data such as dead space volume. The interfaces can be wired, infrared, Bluetooth, or USB. A card slot is also preferably provided. Interface 8 can also be implemented as a LAN interface or another interface for internet connectivity. An oxygen inlet valve can be adapted to the ventilation device within the device housing. It is conceivable to further enrich the breathing gas with oxygen to improve patient care.

[0040] The interface 8, for example implemented as a card slot or USB port, allows data unrelated to therapy to be loaded into or executed by the ventilator 20 according to the invention. For example, photos or videos can be displayed on the screen 13 via the interface 8 using storage media. If the device 20 detects external storage media, the user must confirm a prompt in the control panel 14, after which the data is either stored or executed on the ventilator 20.

[0041] The ventilator 20 according to the invention is designed to be connected to a patient via a tube and a patient interface to provide ventilation. It comprises a source of respiratory gas, which is designed, for example, as an electric motor with a fan wheel, a device for determining the pressure and / or flow and / or volume of the respiratory gas, and a control unit 19, which is designed to determine a respiratory gas pressure for each respiratory cycle based on a predetermined value for the patient and / or based on measurement signals for the parameters pressure and / or flow and / or volume, and to regulate the source of respiratory gas such that the respiratory gas pressure is generated.

[0042] The control unit 19 is further designed to determine the current pressure and / or flow and / or volume of breathing gas and to display the current value via the operating and information system 3 connected to the control unit 19. The control unit 19 is also designed to determine trend changes in its calculations over time with respect to one or more parameters, whereby the trend changes can be displayed on the display 13.

[0043] Furthermore, the control unit compares 19 such parameter values, which are specified by a user, for example, upper and lower pressure limits, a maximum tolerable number of apneas per unit of time, or a maximum tolerable leakage, with the current values ​​and generates user information about deviations from the specifications. This user information is preferably visualized graphically via the operating and information system 3.

[0044] Apneas and hypopneas are detected from the measured airflow by a decrease in tidal volume (or time) lasting at least 10 seconds. Additionally, snoring is detected via pressure and flow fluctuations, and flattening is detected via the inspiratory flow contour. For each sufficiently long nightly therapy session, indices are calculated from this data, namely: AHI (number of apneas and hypopneas per artifact-free therapy duration), RDI (number of all respiratory events per artifact-free therapy duration), percentage of breaths with flattening, and percentage of breaths with snoring. Data relating to the patient's usage patterns or the duration of device use are also preferably collected. This data is collected and stored daily, weekly, or monthly. If necessary, the usage data, possibly along with a device identifier, is retrieved and transmitted via an internet or mobile network connection.

[0045] Fig. 2 Figure 3 shows the operating and information system 3 for the ventilator 20 with an illuminated or backlit display 13 for showing control panels 14 or information for the user and the touch-sensitive input unit 15 in close proximity to the displayed control panel 14. In a specific embodiment, it is a human-machine interface in the form of a so-called touchscreen, of which the skilled person knows different types, all of which are suitable as components of the operating and information system 3.

[0046] In the area of ​​display 13, at least a first control panel 14a and a second control panel 14b are shown. The control unit 19 is designed to display the menu on display 13.

[0047] A processing unit 18, which is coupled to the display 13 and the touch-sensitive input unit 15, is designed to detect operation of the control panel 14 via the input unit 15 and, depending on this, to control a function of the menu via the control unit 19. Preferably, a menu assigned to a control panel 14b, 14c, 14d, etc., is displayed on the display 13 spatially adjacent to the control panel or at the same location on the control panel. Simultaneous or sequential operation of other control panels 14b, 14c, 14d, etc., via the input unit 15 can also be detected by the processing unit 18. The processing unit 18 then causes the control unit 19 to call up the menu assigned to the selected control panel at the first level (= submenu). Preferably, a menu assigned to a control panel 14b, 14c, 14d, etc., is displayed on the display 13 in a location adjacent to the control panel or at the same location on the control panel.The associated submenu is displayed on screen 13 in a location adjacent to the control panel or menu, or at the same location on the control panel or menu.

[0048] A submenu is displayed on the screen 13 from the control unit 19. Preferably, the submenu is displayed in essentially the same location as the menu from which it originates. Further control panels 14 or information can then be displayed within the submenu. Navigation to multiple submenus is generally possible. However, preferably, the branching is limited to no more than two menu levels. To return from a submenu to the main menu, a control panel 14 is always provided in the same location. Activating this panel causes the control unit 19 to display the menu of the next higher hierarchy level on the screen 13.

[0049] The currently set ventilation pressure in mbar is displayed in the lower right corner, along with an associated control panel 14e. An information field with an associated control panel 14a is displayed in the upper right corner.

[0050] For example, if the ventilation pressure is to be changed as an operable setting function, the user simply touches the corresponding field of display 13, which shows the information about the current pressure, here the control panel 14e. The control unit 19 then initiates the display of a control panel.

[0051] In the simplest case, two control fields in the form of plus and minus symbols 14f2, 14f3 are visualized above and below or to the right and left of the selected adjustable setting function. Activation of the control fields is detected by the processing unit 18, which then prompts the control unit 19 to change the value of the adjustable setting function according to the input and visualize it in the area of ​​the display 13. The changed parameter is displayed by the control unit 19 in the corresponding field of the display 13 and simultaneously, or only after user selection, is set and applied as a new parameter to the blower of the ventilator 20 via a control signal. Preferably, the set value and the actual value are visualized first. Once the actual value equals the set value, only the actual value is displayed.

[0052] The parameters set in this way are simultaneously written by control unit 19 to a memory, which serves as a temporary storage area for the parameter values ​​currently being applied. The memory always stores at least the most recently entered and applied values. When the undo function is activated, the memory always outputs these most recent values ​​first.

[0053] Fig. 4 A control panel 14f is shown in the form of a number line or bar. Parameters can be set there with many adjustment levels, such as ventilation pressure, frequency, flow, volume or background frequency (for example from 6 to 40 rpm).

[0054] Preferably, the entire pressure range is visualized as a number line or bar on display 13 for setting the therapy pressure. This visualized number line also serves as the control panel 14f. The pressure control panel 14f is touch-sensitive across the entire visualized setting range. The user can therefore select the desired value with just a touch of the desired pressure area. The detected value is visualized in an additional field 14f1. If the detected and visualized value is correct, the user can apply it by touching the additional field 14f1. Fine adjustment in 0.5 increments is also possible using the plus and minus symbols 14f2 and 14f3.

[0055] A control panel in the form of a list selection is displayed when setting many options, such as selecting the language for the user interface or the setting parameters for ventilation. The selectable options are displayed in text or symbolic form, and the desired option is selected by touching it. The control unit 19 then sends a control signal to execute the selection or display the setting range. Fig. 5a In section 5b, all settings are visible to the user at a glance. Each value can be selected for adjustment directly by touch.

[0056] A control panel can then be in the form of a number line or bar, as in Fig. 4 It can be visualized. Parameters can be adjusted there by touching the desired area.

[0057] According to the invention, the active control panel 14 is highlighted by a more intense color, thereby alerting the user to the setting function, while inactive control panels are visualized in a paler color. The paler color indicates to the user that the panels are not active.

[0058] Fig. 5a A control panel is displayed in graphical form. It visualizes the current or stored pressure values ​​for inspiratory pressure (IPAP), expiratory pressure (EPAP), and end-expiratory pressure (EEPAP).

[0059] If the user wants to change one of these pressures, they must touch a line 14g, 14h, 14i, which represents the pressure range, and then move the pressure range to the desired level by sliding their finger across the display. The selected line moves with the movement, and the value is also displayed. When the user stops touching, the set value is applied. In this example, the user has set the IPAP (see line 14g in Fig. 5a ) reduced from 15 mbar to 13 mbar, which in Fig. 5b is shown.

[0060] The user can also use the EPAP (see line 14i in Fig. 5a ) and the EEPAP (see line 14h in Fig. 5a ) set.

[0061] Fig. 6a It also displays a control panel in graphical form. This visualizes the current or stored pressure values ​​for inspiratory pressure (IPAP), expiratory pressure (EPAP), and end-expiratory pressure (EEPAP).

[0062] If the user wants to change one of these pressures, they must touch a line 14g, 14h, 14i, which represents the pressure range, and then move the pressure range to the desired level by sliding their finger across the display. The selected line moves with the movement, and the value is also displayed. When the user stops touching, the set value is applied. In this example, the user has set the EEPAP (see line 14h in Fig. 6a ) increased from 6 mbar to 7 mbar, which in Fig. 6b is shown.

[0063] The user can also adjust the slopes of the pressure transitions and the pressure waveform.

[0064] Fig. 7a The control panel is displayed graphically. It visualizes the current or saved pressure values ​​for inspiratory pressure (IPAP), expiratory pressure (EPAP), and end-expiratory pressure (EEPAP). The pressure transition slopes and the pressure waveform are also shown. The pressure transition slope from EPAP to IPAP (see line 14k) is shown once as a solid line and once as a dashed, broken line. The dashed, broken line appears when the user touches and moves line 14k.

[0065] If the user wants to change the slope of the pressure transition from EPAP to IPAP, they must touch line 14k, which represents the slope, and then adjust it to the desired gradient by moving line 14k horizontally with their finger – preferably near the start or end points, i.e., close to the EPAP or IPAP. The selected line 14k moves as a dashed line with the movement, while the opposite anchor point of the line remains fixed. During the adjustment process, the selected line appears, for example, as a dashed line or in a different color. The slope value can also be displayed. When the user releases the touch, this set value is applied, and the line becomes solid again.

[0066] Fig. 7b This shows how to set a 14m pressure waveform. The 14m pressure waveform is an exaggeration of the IPAP (see line 14g in [reference]). Fig. 7a ), which the user can adjust. Typically, the IPAP is constant, shown here as a solid line. However, at the user's discretion, the IPAP can be set to rise slightly to a higher IPAP and fall slightly to a lower IPAP, shown here as a dashed line.

[0067] If the user wants to change the pressure waveform 14m of the IPAP, they must touch line 14g, which represents the IPAP, and then move it vertically to adjust the desired waveform. The maximum pressure of the waveform is always set in the area of ​​touch. The rising and falling edges follow passively. If the user touches line 14g in the initial area (left) and moves it vertically, the resulting waveform 14m will have a steep rise with a pressure maximum at the beginning and then fall. If the user touches line 14g in the final area (right) and moves it vertically, the resulting waveform 14m will have a gentle rise with a pressure maximum at the end and then fall sharply (see Fig. 7c ).

[0068] If the user touches line 14g in the middle and moves it vertically, the resulting waveform 14m will have a symmetrical rise and fall, with a pressure maximum in the middle.

[0069] The following also applies to the explanations for all figures: The displayed value range on the number line is scaled so that it always encompasses exactly the range between the currently possible minimum and maximum for the setting of the respective parameter. Possible presets or limit values ​​are taken into account.

[0070] Alternatively, a universal range of values ​​is always displayed, and the currently valid minimum and maximum (default settings or limits) are indicated, for example by additional lines or hatching of either the valid or the invalid range of values.

[0071] The old value, which is still active for ventilation until the new value is confirmed, is also displayed. This can be done, for example, with an additional line or a color-coded marker.

[0072] The currently selected value can be marked not only by a colored line, but also, for example, by an arrow pointing down or down the scale, or by coloring a number on the scale.

[0073] Two or more values ​​can be set simultaneously on a scale. For example, the upper and lower pressure limits. Both are clearly distinguished, for example, by different colors or hatching. Switching between the two values ​​is done either within the scale itself. For example, the parameter closest to the touch point is always adjusted. Alternatively, switching between the two parameters must be done outside the scale, for example, by activating the tiles. Another option is to allow a sensitive time window to remain after the first value has been set, enabling both values ​​to be adjusted sequentially on the displayed number line without having to navigate through menus.

[0074] In The scale doesn't always have to consist of numbers. It could also switch between different ranges described by words or a combination of words and numbers, for example "Small - Medium - Large - Very Large", or "Off - Light - Normal - Strong", "Off - 0, 1, 2, ... Max".

[0075] While setting numerical values ​​on the scale, there could be a separate visual feedback area. For example, when setting the ramp steepness for the in-extrusion ramp, a trapezoid could be displayed at another position on the screen as a simplification of a print profile, where the ramp is shown as steeper or flatter, analogous to the selection on the control panel.

[0076] Acoustic feedback is also provided. For example, a tone or sequence of tones becomes louder the larger the currently selected value on the control panel, and vice versa. Alternatively, color feedback is provided, such as a color change of the scale or the marker of the current value when it exceeds or falls below certain values.

[0077] The following parameters can also be displayed via a control panel: ramp gradients for the pressure transition from inspiration to expiration and vice versa, trigger sensitivity, duration of the pressure ramp at the start of therapy (soft start), volume of acoustic outputs, brightness of a display or additional LEDs or display units, sensitivity of a touchscreen or certain algorithm parts, target volume, target ventilation, patient characteristics such as height, age, weight, BMI or related values, humidifier level, setpoints for at least one temperature or humidity of the respiratory gas, time, date, time zone, duration of a statistical period, size of displayed information, target value for compliance in minutes or hours, and at least one subjective patient well-being indicator.

[0078] Instead of a linear display, the control panel can also be circular or oval, thus simulating, for example, a rotary dial.

[0079] According to the invention, it is also provided that a virtual and rotatable control knob or a scroll wheel is displayed.

[0080] The number scale does not have to be linear. It can also be logarithmic, for example, or have a higher resolution in the area of ​​the current value, similar to a magnifying glass, and a coarser resolution further away from it.

[0081] Alternatively, it is possible to switch between a more detailed display of a sub-area, for example around the current value, and a display of the entire area.

[0082] To tailor the pressure or flow rate to the individual patient, the rate of pressure or flow increase can be set. This determines how long it takes for the pressure to rise from the lower to the upper pressure level. The time is set in seconds, or, in the case of flow, the gas flow rate in liters per minute. At the beginning of inspiration, the air is delivered at a lower flow rate than set. The gas flow rate increases during inspiration until it reaches the set value. These settings directly affect the delivered tidal volume (VT). The pressure increase or decrease is adjustable and preferably ramped. The pressure increase can occur with a smooth, continuous ramp to the elevated pressure level, or with a variable ramp rate.The value of the increased or decreased pressure level is preferably adjustable in mbar increments or fractions of mbar. The ramp steepness for the pressure increase or decrease can be displayed graphically at another position on the screen, for example as a trapezoid to simplify a pressure profile, where the ramp is displayed as steeper or shallower, analogous to the selection on the control panel.

[0083] Fig. 8 This shows a graphical setting aid for the ramp gradient for the transition from expiratory pressure to inspiratory pressure (marked in green). The current level can be adjusted using the slider or ruler, or alternatively with the + and - buttons. The ruler, with its green marker, serves not only as an adjustment tool but also as a display element. This offers the advantage that even inexperienced users can see the value directly during the adjustment process.

[0084] In the example shown, it can be seen that the graphical setting aid provides the user with at least two (see 31, 34), preferably three (see 31, 32, 34) feedback on the setting. The operating device for a ventilator includes a touch-sensitive graphic display 3, 13, 14, 15, which at least temporarily represents the value range for a ventilation parameter 14a ... 14x, here the ramp rate 30, and numerically displays at least individual values ​​of the ramp rate (see 31). In addition, a memory for the value of the ramp rate is used for at least one data point associated with the value range and at least one digit 14a ... 14x of the touch-sensitive graphic display that is logically connected to the data point.Furthermore, the following are provided: a switching logic 18 which, when the position of the touch-sensitive graphic display assigned to the data point is touched, causes a display of at least one numerical value 32 assigned to the data point and / or a confirmation field 33 for the numerical value 32, and a switching logic 18 which, when the numerical value 32 or the activation field 33 is touched, applies this numerical value 32 to the assigned respiratory gas parameter and writes it to the memory along with the assigned respiratory gas parameter.

[0085] The control panel is designed in the form of a number line or ruler. The entire range of values ​​is visualized as a number line or bar on display 13. The visualized number line also serves as a control panel (14f). The control panel is touch-sensitive across the entire visualized setting range. The desired value can be selected with just a touch of the desired area.

[0086] A finger press or touch within the ruler is evaluated in terms of its position in such a way that it is not necessary to hit exactly one of the numbers "1", "2", or "3", but rather the finger press is assigned to the nearest number. The recognized value 32 is visualized in an additional field 14f1. The recognized value 32 can also be adjusted using the + / - symbols (see 14f2, 14f3).

[0087] Preferably, not only are individual values ​​31 of the ramp gradient numerically displayed, but also the selected value 33 of the ramp gradient is numerically displayed. A graphical visualization 34 of the selected ramp gradient is also provided.

[0088] Alternatively or additionally, as in relation to Fig. 7a, 7b , 7c During this process, the ramp from inspiratory to expiratory pressure can also be adjusted.

[0089] Fig. 9 shows analogous to Fig. 8 The trigger sensitivity setting is 40. The threshold value 41 is shown schematically as a green line. Compared to Fig. 7a, 7b , 7cIt can be seen that values ​​other than numerical values ​​can also be selected in the slider or ruler; in this case, "A" for the "Auto" level. The operating device for a ventilator comprises a touch-sensitive graphic display 3, 13, 14, 15, which at least temporarily represents the value range for a ventilation parameter 14a ... 14x, here the trigger sensitivity 40, and numerically displays at least individual values ​​42 of the trigger sensitivity, a memory for the value of the trigger sensitivity, and at least one data point connected to the value range. Also used are: at least one switching logic point 14a ...14x of the touch-sensitive graphic display and a switching logic 18 which, when the position of the touch-sensitive graphic display associated with the data point is touched, causes a display of at least one numerical value 32 associated with the data point and / or a confirmation field 33 for the numerical value. Also provided is a switching logic 18 which, when the numerical value 32 or the confirmation field 33 is touched, applies this numerical value 32 to the associated breathing gas parameter and writes it to the memory along with the associated breathing gas parameter.

[0090] The control panel is designed in the form of a number line or ruler. The entire range of values ​​is visualized as a number line or bar on display 13, and this visualized number line is also configured as control panel 14f. The control panel is touch-sensitive across the entire visualized setting range, and the desired value can be selected with a single touch of the desired area. A finger press or touch within the ruler is evaluated in such a way that it is not necessary to precisely touch one of the numbers "1", "2", or "3", but rather the finger press is assigned to the nearest number. The recognized value 32 is visualized in an additional field 14f1.

[0091] The detected value can be further adjusted using the + / - symbols. Preferably, not only are individual trigger sensitivity values ​​42 displayed numerically, but the selected trigger sensitivity value 43 is also displayed numerically. A graphical visualization 41 of the selected trigger sensitivity is also provided. Three fixed trigger levels are available. These can also be adjusted using the + / - symbols to fine-tune the trigger for individual patients. If level "A" is selected for the "Auto" level, the trigger adjusts adaptively within predefined limits, which are also visualized graphically.

[0092] In Fig. 10 The graphical setting aid for at least one inspiratory and one expiratory pressure is shown. The position of the pressure tile below the graphic clarifies the inspiratory and expiratory pressures as well as the pressure stroke PDIFF (see also 54). The colors of the tiles represent the following: Green: currently selected parameter that can be adjusted via slider or plus / minus buttons; Grey: parameter that can be selected as an alternative for adjustment; Black: parameter displayed for informational purposes, resulting from the settings.

[0093] Alternatively, the slider could display not only the value of the currently set parameter in a color, but also the values ​​of other parameters with a marker that differs in shape and / or color. The operating device for a ventilator comprises a touch-sensitive graphic display 3, 13, 14, 15, which at least temporarily represents the value range for a ventilation parameter 14a ... 14x, here the pressure values ​​50 for IPAP and / or EPAP and / or EEPAP, and numerically displays at least individual values ​​51 of the trigger sensitivity, a memory for the pressure value, at least one data point connected to the value range, and at least one switching logic point 14a ...14x of the touch-sensitive graphic display, a switching logic 18 which, when touching the position of the touch-sensitive graphic display assigned to the data point, causes a display of at least one numerical value 52 assigned to the data point and / or a confirmation field for the numerical value, a switching logic 18 which, when touching the numerical value 52 or the actuation field, applies this numerical value 52 to the assigned respiratory gas parameter and writes it to the memory along with the assigned respiratory gas parameter.

[0094] The control panel is designed in the form of a number line or ruler. The entire range of values ​​is visualized as a number line or bar on display 13, and this visualized number line is also configured as control panel 14f. The control panel is touch-sensitive across the entire visualized setting range, and the desired value can be selected with just a touch of the desired area. A finger press or touch within the ruler is evaluated in such a way that it is not necessary to precisely hit one of the numbers; rather, the finger press is assigned to the nearest number. The recognized value 52 is visualized in an additional field 14f1.

[0095] The detected value can be further adjusted using the + / - symbols. Preferably, not only are individual pressure values ​​52 displayed numerically, but the selected value is also displayed numerically. A graphical visualization 53 of the selected pressure is also provided. This can also be adjusted using the + / - symbols. Preferably, the resulting pressure stroke is also displayed as a numerical value 55 and visualized graphically for informational purposes (see 54).

[0096] In Fig. 11 is used as a supplement to Fig. 8 in combination with the current ramp gradient "1", "2" or "3" (see 31 in Fig. 8 The settings of other logically related parameters are also displayed informatively. This allows the user to select the appropriate value without having to remember the other parameters. As a consequence of the current ramp gradient and the other parameters, the currently valid ramp time in ms is displayed (see 35 in [reference missing]). Fig. 11 ) calculated and also presented informatively.

[0097] Fig. 12 Figure 60 shows a setting of the ratio "Ti / T" of inspiratory time to total tidal time in %. Additionally, a selected respiratory rate "Fmin" (see Figure 61) is displayed. As a consequence of the set respiratory rate "Fmin" and the set ratio "Ti / T", the inspiratory duration "Ti" (see Figure 62) and the expiratory duration "Te" (see Figure 63) are calculated and displayed.

[0098] In the lower half of Fig. 12 An alternative version is shown in which the inspiratory duration "Ti" is set. In combination with the selected respiratory rate "Fmin", the expiratory duration "Te" and the ratio "Ti / T" are automatically calculated. The operating device for a ventilator comprises a touch-sensitive graphic display 3, 13, 14, 15, which at least temporarily represents the value range for a ventilation parameter 14a ... 14x, here the inspiratory duration 62, and numerically displays at least individual values ​​64, a memory for the inspiratory duration, at least one data point associated with the value range, and at least one digit 14a ... logically connected to the data point.14x of the touch-sensitive graphic display, a switching logic 18 which, when touching the position of the touch-sensitive graphic display assigned to the data point, causes a display of at least one numerical value 65 assigned to the data point and / or a confirmation field for the numerical value, a switching logic 18 which, when touching the numerical value 65 or the actuation field, applies this numerical value 65 to the assigned respiratory gas parameter and writes it to the memory along with the assigned respiratory gas parameter.

[0099] The control panel is designed in the form of a number line or ruler. The entire range of values ​​is visualized as a number line or bar on display 13, and this visualized number line is also configured as control panel 14f. The control panel is touch-sensitive across the entire visualized setting range, and the desired value can be selected with just a touch of the desired area.

[0100] A finger press or touch within the ruler is evaluated in terms of its position, so that it is not necessary to hit one of the numbers exactly, but rather the finger press is assigned to the nearest number. The recognized value is visualized in an additional field. The recognized value can also be adjusted using the + / - symbols. Preferably, not only are individual values ​​displayed numerically, but also the selected value. A graphical visualization of the selected value is also provided. This can also be adjusted using the + / - symbols. Preferably, the resulting exhalation time of 63 is also displayed as a numerical value and / or graphically visualized for informational purposes.

[0101] Fig. 13 Figure 1 shows the described circular design of the control element. A rotary dial 73, which can be operated with a finger, is simulated on the touch-sensitive display 13. A similarly circular display element 72 is positioned around the control panel, which displays at least the currently set value 71, in this example 19 minutes, and preferably also the value limits or the value range, in this example 0 to 45 minutes. The display is as a number and, particularly preferably, additionally by a colored and / or thicker marker 74, which represents the current values ​​in relation to the entire value range.

[0102] The operating device for a ventilator comprises a touch-sensitive graphic display 3, 13, 14, 15, which at least temporarily represents the value range for a ventilation parameter 14a ... 14x and numerically displays at least individual values ​​71, a memory for at least one data point associated with the value range, at least one position 14a ... 14x of the touch-sensitive graphic display logically connected to the data point, a switching logic 18 which, when the position of the touch-sensitive graphic display logically assigned to the data point is touched, causes a display of at least one numerical value 71 assigned to the data point and / or a confirmation field for the numerical value, a switching logic 18 which, when the numerical value 71 or the activation field is touched, applies this numerical value 71 to the assigned respiratory gas parameter and writes it to the memory along with the assigned respiratory gas parameter.

[0103] The control panel is designed as a rotary knob 73 or dial 73. The entire value range, or a portion thereof, is visualized as a ring of numbers 72 on the display 13. The visualized ring of numbers 72 is also designed as a control panel 14f. The control panel 14f is touch-sensitive across its entire visualized setting range. The desired value can be selected with just a touch of the desired area. A finger press or touch within the ring of numbers 72 is evaluated with respect to its position in such a way that it is not necessary to press exactly one of the numbers, but rather the finger press is assigned to the nearest number.

[0104] Alternatively, swiping across the number ring 72 is recognized as a setting action, and stopping the swiping motion as a selection. The value detected when the motion stops, the detected value 71, is visualized in an additional field 14f1. The detected value can also be adjusted using the + / - symbols. Preferably, not only individual values ​​are displayed numerically, but also the selected value. A graphical visualization of the selected value is also provided. This can also be adjusted using the + / symbols.

[0105] The parameter currently being set, 75, is preferably displayed with a name and / or an internationally understood symbol and / or its unit. In the example shown, the parameter could be the ramp time of a therapy device used as a sleep aid, displayed in minutes. Alternatively, therapy pressures or power levels of a humidifier, among other things, could be displayed and adjusted.

[0106] If the user rotates the illustrated rotary dial 73 with their finger, preferably clockwise, the selected value increases, in this example from 19 to 32 minutes. A rotation in the opposite direction decreases the selected value. Once the desired value is reached, it can be accepted and applied by the device. This typically occurs either after a waiting period without further adjustment or after pressing a confirmation button or a confirmation area 76, which is marked, for example, with "Accept," "OK," "Apply," a checkmark symbol, or similar. This area is particularly preferably located in the center of the illustrated rotary dial 73.

[0107] Fig. 14 Figure 1 shows an alternative embodiment. Here, the control element "rotary wheel" and the circular display element are located side by side or one above the other. This is a preferred embodiment if no touch-sensitive display element is used, but only a graphic display element 80 with a separately implemented mechanical rotary push button 81. This embodiment offers the advantage that the mechanical rotary push button 81 can be preferably used for fine adjustments due to its haptic feedback or improved operability. The graphic visualization of the adjustment process and / or the selected value and / or the available value range, decoupled from the mechanical rotary push button 81, offers the advantage that a larger and improved display can be chosen than would be possible with a scale next to the mechanical rotary push button 81.

[0108] Confirming a selected value is preferably done by pressing the rotary push-button 81.

[0109] Otherwise, the type of presentation and setting is the same as in the example of Fig. 13 comparable, which is why the description to Fig. 13 also for the example of Fig. 14 can be used.

[0110] According to the invention, a (start / stop) control surface can be displayed 14 times on the touchscreen or a mechanical (start / stop) control element 2 can be used. Fig. 15 It is provided that the activation of which causes the operating and information system 3 to start or stop ventilation via the control unit.

[0111] According to the invention, the (start / stop) control area 14x on the touchscreen is designed differently depending on the situation. For example, if ventilation is not active but can be started, the (start / stop) control area 14x on the touchscreen is, for example, at least partially colored green or displays a start symbol and, for example, additionally the text "Ventilation Start". If ventilation is active and can be stopped, the (start / stop) control area 14x on the touchscreen is at least partially colored red or displays a stop symbol and, for example, additionally the text "Ventilation Stop".

[0112] For example, it is intended that the (start / stop) control surface will appear 14 times in the same position on the touchscreen and / or in the same size, otherwise unchanged.

[0113] When the (Start / Stop) control button is pressed 14 times on the touchscreen to stop ventilation ("Ventilation Stop"), the control unit saves current ventilation settings, such as current pressure values, and when the (Start / Stop) control button is pressed again 14 times to start ventilation, these settings are read out and activated for ventilation, especially if no changes were made to the ventilation settings during the ventilation stop.
