Description

[Technical Field]

[0001] The present invention relates to an artificial ventilator as set forth in claim 1 and a method for controlling an artificial ventilator as set forth in claim 5. [Background technology]

[0002] Ventilators are used in both static situations (e.g., in clinical or home environments) and dynamic situations (e.g., emergency services), and it is important that they operate reliably and without malfunctions.

[0003] A further requirement for this type of ventilator is ease of operation, as operator error can have disastrous consequences for the patient being ventilated using the ventilator.

[0004] The ventilator disclosed in Patent Document 1 is connected to a sensor system and a control system, and the control system is connected to a display means. The sensor system acquires measurement data and transmits it to the ventilator. Display data provided by the control system based on the acquired measurement data can be displayed on the display means as animated graphics units.

[0005] In the artificial ventilator disclosed in Patent Document 2, a graphical element shaped like a lung is displayed on a display means. The volume change that occurs in the lung during ventilation with each breath is displayed as an animated change in the size of the lung figure. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] International Publication No. WO02 / 071933 Pamphlet [Patent Document 2] European Patent No. 1984805 Summary of the Invention [Problem to be solved by the invention]

[0007] It is therefore an object of the present invention to provide a ventilator that is easy for the operator to operate and safe to use, and that allows the operator to utilize the acquired measurement data in an optimal manner, both qualitatively and quantitatively.A further object of the present invention is to provide a method for controlling such a ventilator. [Means for solving the problem]

[0008] This object is achieved by the features of the independent claims. The drawings and the dependent claims show useful further refinements.

[0009] In the following description, when the expression "or" is used to connect two words, it means "and / or." This should be understood to mean not only that the first word "or" the second word can be used literally, but also that the first word "and" the second word are included.

[0010] The ventilator of the present invention is connected to a sensor system and a control system, which may be an integral part of the ventilator.

[0011] The sensor system can also be a component of the ventilator and is configured to acquire at least two measurements and transmit the acquired measurements to the ventilator or its control logic module.

[0012] In one embodiment, the sensor system includes at least two measurement sensors, each acquiring measurement data from one source, and the sensors are advantageously configured in different ways to acquire different measurement data. In another embodiment, the sensor system includes only one measurement sensor, thereby acquiring at least two items of measurement data from multiple sources.

[0013] The control system is linked to a display means comprising a configurable screen. The term "configurable screen" in this context means a screen on which not only the individual depicted elements can be seen, but also the totality of all depicted elements and their arrangement. In this configuration, the configurable screen can acquire measurement data autonomously or by means of a graphic logic module or a control logic module, convert them into geometric elements and then display them. Furthermore, the configurable screen can change existing elements (geometric and / or graphical) in the graphics unit and convert modifications in the graphics unit into parameters that can be used to control the control system.

[0014] The control system may be suitably configured to provide display data based on the acquired measurement data for display on a first graphics unit of the at least one display means, advantageously the first graphics unit being a pictorial representation of the lungs or other organs affected by the ventilator, and more advantageously the first graphics unit comprising an animated representation.

[0015] Its unique configuration and elemental integration provide the operator with a ventilator that is easy to operate and reliable. The configurable screen significantly improves operator visibility compared to known ventilators. This ensures that the operator always has a qualitative and quantitative understanding of the ventilator.

[0016] Preferably, the control unit is provided with a control logic module or a graphics logic module, and the acquired measurement data is processed by either the control logic module or the graphics logic module, or by both the control logic module and the graphics logic module. Furthermore, the control logic module and the graphics logic module may form a common unit, for example integrated within the ventilator, and the ventilator may be controlled by at least the control logic module.

[0017] All of the above features in themselves ensure stable operation of the ventilator, thereby providing high reliability in use.

[0018] Advantageously, the control logic module and the graphics logic module each have an information processing unit, so that the acquired data can be processed in each module for further use.

[0019] Preferably, the configurable screen is a touch-sensitive screen, so that it can serve not only as a display data output but also as an input means. Such touch-sensitive screens are also known as touchscreens. Further non-limiting examples of such touch-sensitive screens include touchpads, smartphones, and smartwatches, which are connected to the ventilator or its components directly or indirectly via a wireless connection such as Bluetooth, WLAN, etc.

[0020] Preferably, a sensor is provided which captures at least one area of ​​the at least one display means, making it possible to easily detect any unexpected changes in the display and, if necessary, to initiate corresponding measures such as an alarm, an internal device test, etc. For example, if the display means fails, a message can be sent to the user, for example on his / her pager or mobile phone, so that immediate action can be taken.

[0021] Additionally, the sensor can monitor a visual indication, providing an additional independent monitoring unit in addition to monitoring through the control system, further enhancing the safety of the ventilator.

[0022] Advantageously, the sensor may be placed facing, or more advantageously directly adjacent to, the at least one display means, thereby achieving a simple structural arrangement, and may be a component of the sensor system linked to the ventilator.

[0023] The method according to the invention controls the above-mentioned ventilator and is characterized by the following steps:

[0024] At least two items of measurement data are acquired by the sensor system (step a)), and then the acquired measurement data are transmitted from the sensor system to the ventilator or its control system (step b)).

[0025] Thereafter, at least one of the acquired items of measurement data is received by the ventilator or its control system (step c).

[0026] More advantageously, the individual items of acquired measurement data are then processed by the ventilator or its control system.

[0027] Thereafter, display data created based on the received measurement data of at least the individual items is provided (step d)).

[0028] Then, the display data of at least the individual items is displayed on a first graphics unit of the at least one display means in a first animated representation of the respiratory gas (step e)), so that the display data can be visually and intuitively recognized by the operator.

[0029] This provides a reliable method of controlling a ventilator, whereby the operator of the ventilator (especially a medical professional) is informed, at least visually, of changes in respiratory parameters in the ventilator and can take action to prevent injury to a patient being ventilated by the ventilator.

[0030] The individual display data may include acquired, received, or processed measurement data, or any combination of acquired, received, and processed measurement data. The term "processed measurement data" includes any mathematical or logical modification of acquired measurement data. The acquired measurement data is obtained by the sensor system. Alternatively or additionally, the acquired measurement data is entered by the ventilator operator on an input means.

[0031] Advantageously, representing the display data of the at least individual items by at least individual geometric elements provides additional visibility for the operator, making the operator visually sensitive to the display data of the at least individual items.

[0032] In this way, advantageously, each of the display data for an individual item describing the same respiratory parameter is displayed using geometric elements with the same geometric properties, and each of the display data for an individual item describing a different respiratory parameter is displayed using geometric elements with different geometric properties.

[0033] The term "geometric properties" of a geometric element should be understood to mean the shape, color and size of the element, where element shape should be understood to mean a two-dimensional shape (circle, triangle, ellipse, polygon, etc.) or a three-dimensional shape (sphere, pyramid, cone, cube, etc.).

[0034] Advantageously, providing the display data in step d) by the control system can facilitate providing the display data, for example by the control logic module.

[0035] Alternatively or additionally, the display data may be provided by a graphic logic module, which provides a simplified representation of the display data in addition to a graphical representation of the display data, thereby enabling an operator to quickly detect and quickly address any malfunctions in the ventilator.

[0036] Advantageously, having the graphic logic module be an integral part of the display means ensures that the ventilator is of a simple construction.

[0037] Advantageously, the metrology data received by the control logic module of the control system (step c)) can be transmitted to the graphics logic module to facilitate a graphical display of the metrology data on the at least one display means.

[0038] Advantageously, the graphic logic module can process at least the individual items of transmitted measurement data to provide display data, which feature reduces the amount of measurement data to be processed.

[0039] Advantageously, in step c) the received measurement data can be classified in the control system according to measurement data categories, so that measurement data for at least individual items belonging to at least one measurement data category are transmitted to the graphic logic module, thereby reducing the amount of measurement data that the graphic logic means has to process.

[0040] Advantageously, sending all metrology data belonging to said at least one metrology data category to said graphic logic module ensures improved statistics on the amount of metrology data subsequently processed.

[0041] Alternatively or additionally, by transmitting measurement data of at least individual items belonging to a certain measurement data category to the at least one display means, for example, it is possible to prevent inaccurate display of the displayed data.

[0042] Advantageously, by transmitting all measurement data belonging to said certain measurement data category to said at least one display means, statistics in the visualized display data can be reliably improved.

[0043] Preferably, by displaying at least individual items of display data on the at least one display means in an additional representation that can be animated, an improvement in the visual acceptance of the ventilator operator with respect to a particular respiratory parameter on the display means can be ensured, and thus he / she can more easily make the necessary, and in particular the correct, decision. In this case, in addition to the first graphics unit, additional animated representations can be rendered, which can be easily visually recognized by the operator.

[0044] Advantageously, displaying the display data of at least the individual items in the at least one display means in the further animatable representation with at least further individual geometric elements can facilitate visual differentiation by the operator of the ventilator of the display data of the individual items, and thus of the individual respiratory parameters.

[0045] Advantageously, by modifying at least one of the geometric properties of the individual geometric elements in one of the animatable representations, the operator of the ventilator can observe the time-dependent variation of the displayed data of the individual items, and thus of the individual respiratory parameters, allowing the operator of the ventilator to quickly and easily address modifications, which in turn can improve the reliability of the ventilator.

[0046] Preferably, the display data of said at least individual items is displayed on said further animatable representation in a first graphics unit of said at least one display means, thereby further improving the visual distinguishability of the display data of said individual items by the ventilator operator.

[0047] Preferably, at least one information processing unit in the control logic module or the graphic logic module calculates at least one distribution of the respiratory gas using the measurement data of the received individual items, thereby statistically eliminating inaccurate measurement data and thus generating an improved measurement data set.

[0048] Alternatively or additionally, in conjunction with the respiratory gas distribution calculation, the measurement data of the received individual items can be used to calculate the location of the respiratory gas, and in conjunction with a statistical evaluation of the measurement data, the location of the respiratory gas, which is known to the operator of the ventilator, can also be calculated.

[0049] Preferably, the distribution of the respiratory gas is displayed in at least a first animatable representation of the respiratory gas, so that an operator of the ventilator can quickly perceive an interruption in the breathing procedure or a malfunction of the ventilator.

[0050] Alternatively or additionally, the location of the respiratory gas may be displayed in at least a first animatable representation of the respiratory gas, so that a malfunction of the ventilator may be readily apparent to an operator of the ventilator.

[0051] Advantageously, the animatable representation of the respiratory gas can be displayed using the at least one geometric element so that it can be quickly addressed by an operator of the ventilator who is trained in the individual geometric elements.

[0052] Preferably, said at least a first graphics unit of said at least one display means can be modified at least in an area so that for example an operator can actively interact with said graphics unit.

[0053] More advantageously, modifications to at least one region of the first graphics unit generate control values ​​that are then transmitted to the control system. This feature ensures that the operator of the ventilator has direct access to the control system via the at least one graphics unit, thereby simplifying and increasing reliability of operation of the ventilator.

[0054] Preferably, rendering said at least one first animatable representation of a respiratory gas on said at least one first graphics unit of said display means causes said at least one first animatable representation of said respiratory gas to be represented using at least individual items of display data, thereby ensuring improved visual sensitivity of the ventilator operator to said display data.

[0055] Preferably, the at least one respiratory parameter is described by the at least individual display geometric elements, which represent at least individual items of display data, allowing an operator to be visually trained on each individual geometric element and to assign the at least one respiratory parameter to that geometric element.

[0056] Advantageously, said at least individual display geometric elements describe at least one of the respiratory parameters belonging to the set consisting of an oxygen parameter, a carbon dioxide parameter and a pulmonary pressure parameter and are represented by at least one set of characteristic geometric properties, which means that said respiratory parameters can be visually displayed on said at least one display means.

[0057] Preferably, the at least one first animatable representation of the respiratory gas shows an exhausted component of the respiratory gas separated from a fresh component of the respiratory gas by displaying the individual components of the respiratory gas with different and distinct geometric properties, thereby allowing an operator of the ventilator to have a quick overview and quickly address any malfunctions in the ventilator.

[0058] Preferably, the measured data of the individual respiratory parameters are displayed in an animated manner to allow the operator to easily address any malfunctions in the ventilator.

[0059] Alternatively or additionally, differential values ​​relating to measurement data derived from various respiratory parameters may be displayed in an animated manner, making it possible to vary various respiratory parameters on the ventilator.

[0060] Preferably, at least one further animatable representation is presented on the display means, consisting of at least a portion of the first graphics unit and highlighting said at least a portion of the first graphics unit together with its geometrical characteristics, thereby sensitizing the visual perception of the ventilator operator to specifically important respiratory parameters.

[0061] Beneficially, the at least a portion of the first graphics unit can be highlighted in a region along with their geometric characteristics to indicate to the ventilator operator areas of importance in the at least a portion of the graphics unit.

[0062] Preferably, said at least one display means comprises a further graphics unit with graphical elements, for example a chart with lines, which graphical elements represent the time variation of at least the displayed data, which represent at least one respiratory parameter, so that the time variation of the respiratory parameter can be monitored retrospectively.

[0063] Beneficially, matching the graphical elements in the chart with at least one geometric characteristic of a corresponding geometric element in one of the animatable representations can improve the orientation of the ventilator operator relative to the at least one display means.

[0064] Preferably, the further graphics unit comprises a bar chart of an animatable representation of the ventilator parameters, so that the most relevant parameters are presented to the operator in a graphical manner.

[0065] In particular, the upper and lower limits of the bar chart may typically represent the maximum and minimum acceptable values ​​for the parameter, thereby delineating to the operator the risk zone for that parameter.

[0066] Preferably, the ventilator is linked to a further display means which takes individual display data from the ventilator, and more advantageously the at least one display means and the further display means are spaced apart from each other, allowing the operator of the ventilator to obtain information about the ventilator from various sources and to react quickly even from a distance.

[0067] Preferably, the ventilator is connected to a tomographic measurement device, which transmits at least individual measurement data from the tomographic measurement device to the control system, which receives them and takes them into account in one of the animatable representations in the first graphics unit, thereby improving the calculation of the distribution or location of the respiratory gas in the first graphics unit.

[0068] Advantageously, the tomographic measurement device being an electrical impedance tomographic measurement device allows for particularly accurate measurement data discrimination to be performed on the ventilator and for particularly accurate calculation of the distribution or location of the respiratory gas in the first graphics unit.

[0069] Further advantages, features and details of the present invention will become apparent from the following description of exemplary embodiments of the invention, which refers to the drawings.

[0073] The ventilator 15 shown in Figure 1 has a housing 17 with connection means 20 arranged on the housing wall 18. A first display means 35 is arranged on the housing front face 19. The control system has a control logic module 25 with an information processing unit 26 (e.g., a processor) and storage means 27 arranged in the housing 17 of the ventilator 15, together with a graphics logic module 36 with an information processing unit 37 (e.g., a processor). The control logic module 25 and the graphics logic module 36 are electrically interconnected by means of data lines 28. The connection means 20 comprises a source connection 21 (e.g., power supply, internet connection, gateway connection, etc.), as well as a ventilation tube connection 22 and a number of sensor connections 23. Measurement data 31 are acquired from an external sensor system 30 by means of the sensor connection 23 and the ventilation tube connection 22 and transmitted to the control logic module 25 using a conventional data connection 32 (cable, WLAN, Bluetooth, etc.) and, for example, an A / D converter (not shown). In the control logic module 25, the acquired measurement data 31 are directly processed and / or transmitted to a graphics logic module 36, at least a part of which is stored in storage means 27. The control logic module 25 is connected via a data line 28 to a first display means 35, on which a sensor 34 is provided, by means of which an area 38 of the display means 35 is captured. The first display means 35 comprises a configurable screen 33, which is associated with a first graphics unit 29 and a second graphics unit 39. The first graphics unit 20 comprises an animatable representation 40 of respiratory gas 41 in the lungs 42. The second graphics unit 39 displays a chart 60 (yt chart) which shows the time variation of one of the items of the display data 65 and the numerical details of the individual items of the display data 62 .The respiratory parameters 16 may be displayed directly on the first display means 35 using display data 62, 65, or may be initially processed in the information processing unit 26 of the control logic module 25 and then displayed as display data 65 on the first display means 35 and / or in its first graphics unit 29 together with the distribution (uniform or non-uniform, Gaussian, exponential, etc.) applicable to the respiratory gas 41. The front housing 19 also has input means 70, which are electrically connected to the control logic module 25 using data lines 28, so that an operator 90 (e.g., a medical professional) of the ventilator 15 can input the individual respiratory parameters 16 and patient parameters 80.

[0074] For example, the ventilator 15 may be connected to a tomographic measurement device (not shown), which transmits measurement data 31 to the control logic module 25. These measurement data 31 are used in processing the respiratory parameters 16 and can be used by the information processing unit 26 of the control logic module 25 to calculate, for example, the distribution of respiratory gases 43 in the lungs 42, which can then be included in an animatable representation 40 of the respiratory gases 41. An electrical impedance tomographic measurement device appears to be a suitable tomographic measurement device.

[0075] 2-11 show various embodiments of animatable representations 40, 50 of respiratory gases 41 in lungs 42 in the first graphics unit 29, the lungs 42 being composed of two lung segments or lobes 44, 45 linked together by a trachea 48 and respective bronchi 46. The constituent components of the respiratory gases 41 (e.g., oxygen, nitrogen, noble gases, carbon dioxide, etc.) are displayed on the first display means 35 using various respiratory parameters 16 or display data 62, 65 and are represented by distinct geometric elements 43, which may be two-dimensional (e.g., circles, dashed lines, triangles, etc.) or three-dimensional (e.g., spheres, rods, pyramids, etc.). The geometric elements 43 making up the animatable representation 40 may be displayed in various ways and with various element sizes, shapes, and colors depending on the embodiment of the ventilator 15 according to the present invention.

[0076] As an example, all breathing parameters 16 or display data 62, 65 are displayed in the animatable representation 40 as circles with different diameters.

[0077] In a healthy state, when the lungs 42 are filled, the geometric elements 43 are uniformly and completely distributed within the animatable representation 40, starting from the trachea 48, through the bronchi 46, and into the two lung segments 44, 45 (FIGS. 2 and 3). The oxygen concentration parameter determined by the control logic module 25 using the inspired oxygen measurement (FiO2_mess), the inspired oxygen fraction definition (FiO2_set), and the oxygen saturation measurement (SpO2), the carbon dioxide parameter measured using the CO2 sensor, and the pulmonary overpressure parameter determined by the control logic module 25 using the proximal and tracheal pressure measurements can each be characterized within the animatable representation 40 by the same geometric elements 43 but with different element colors and / or element sizes (FIG. 3).

[0078] 4 shows an animatable representation 40 of respiratory gas 41 in a lung 42, in which the respiratory gas 41 is concentrated in the lower lung regions 47 of lung segments 43, 44 in a hyperinflatory lung 42. By continuously measuring a continuous positive expiratory pressure parameter (continuous PEEP) using a suitable sensor system 30, an increase in the measured value of the continuous PEEP is evaluated by the control logic module 25 and depicted in the animatable representation 40. To this end, in the animatable representation 40, the expelled respiratory gas component (e.g., the saturated carbon dioxide component or the expelled oxygen component) and the fresh respiratory gas component (newly supplied respiratory gas 41) are depicted in different shades of gray on the same geometric element 43.

[0079] During PEEP measurement, those lung regions 47 (e.g., alveoli) that still contain residual respiratory gas 41 can be visualized using an animatable representation 40 of the respiratory gas 41. The alveoli on the bronchi 46 are visualized using geometric elements 43 (circles) (Fig. 5).

[0080] 6, the restriction in the trachea 48 can be animated using a further representation 50, where the tracheal walls 51 and bronchial walls 52 are shown in bold and in a different color than that of a healthy lung. Additionally, the respiratory gases 41 in the animated representation 40 are arranged so that the geometric elements can be positioned one behind the other in a linear fashion.

[0081] 7 shows a lung 42 with increased lung compliance, determined by control logic module 25 using the compliance as a respiratory parameter 16, in combination with a first animatable representation 40 of respiratory gases 41 showing the spatially restricted distribution of geometric elements 43 in lung segments 44, 45, and a further animatable representation 50 highlighted by colored highlighting of lung lobar walls 53, where the degree of lobar compliance is represented by the width of the colored highlight of lung lobar walls 53. Additionally, the diaphragm 55 is shown in a different color, and when measuring the patient's spontaneous breathing, that color is processed by control logic module 25 and shown in the further animatable representation 50.

[0082] 8 and 9 show an animatable representation 50 of esophageal pressure measurements in the lungs 42, with conclusions drawn from the esophageal pressure measurements being displayed using geometric elements 43 in the form of measurement bars outside the lungs 42. In this case, the control logic module 25 processes measurement data 31 relating to pulmonary and intrapleural pressure measurements in the lungs 42, determining, for example, difference values ​​relating to the measurement data 31, which are then displayed as display data 62, 65 in the animatable representation 50 in the form of measurement bars of different colors.

[0083] 10 and 11 show a representation of the ratio of PEEP to the PEEP-inspiratory pressure (PINSP) difference, as processed by control logic module 25 and visualized within the lungs using an animatable representation 40. As the ratio increases, the element color of geometric elements 43 changes and is highlighted in color within lungs 42 using a measuring bar. According to a preferred embodiment, a method for controlling a ventilator 15 in accordance with the present invention comprises the following steps:

[0084] After the measurement data 31 are acquired by the sensor system 30, they are sent to the ventilator 15 and its control system 24 and processed by the ventilator 15 by storing the measurement data 31 in the storage means 27 and / or processing in the control system 24, where the measurement data 31 are combined with data from the storage means 27 or processed in such a way that they are displayed as display data 62, 65. In the processing process, the information processing unit 26 of the control logic module 25 or the information processing unit 37 of the graphics logic module 36 quantitatively and qualitatively combines the measurement data 31 (and optionally previous measurement data) with the incoming respiratory parameters 16. After combining the respiratory parameters 16, the control logic module 25 assigns the respiratory parameters 16 shown in one of the animatable representations 40, 50 of the respiratory gas 41 to geometric elements 43 and displays them in the first graphics unit 29 with the corresponding element shape, element color, and element size. At the same time, control logic module 25 or graphics logic module 36 identifies variations over time of those same respiratory parameters 16 and causes them to be displayed in the same color or with the same shape or element size in chart 60. At the same time, display parameters 62 are displayed on the second graphics unit.

[0085] As an example, the opening of lung contraction zones (lung recruitment) can be animated. In this case, in a first step, a controllable respiratory pressure (e.g., PEEP) is slowly increased so that its variation over time in chart 60 and the associated geometric element 43 are displayed in the same color in animatable representation 40. Next, ventilation is stopped, and the respiratory pressure (e.g., PEEP) is slowly decreased again, so that its variation over time is displayed in chart 60 and the associated geometric element 43 is displayed in the same color in animatable representation 40, but in a different color from the first step. These two steps are repeated until a maximum difference (hysteresis) between the two steps is determined. The respiratory pressure (e.g., PEEP) thus determined is then passed from control logic module 25 to control system 24 and used as the new control value for ventilator 15. In the event of a change (perhaps an unexpected malfunction), the operator 90 can directly interact with the control system on the ventilator 15 by changing one of the items of display data 62, 65 in the first graphics unit 29, which generates a control value that is sent to the control system 40. The geometric elements 43 described above, representing the individual respiratory parameters 16 or display parameters 65 in the lungs 42, can differ in shape, size and color depending on the embodiment.

[0086] FIG. 12 shows an animatable representation of a parameter 66 in a bar chart 61, which is a second graphics unit 39 on the configurable screen 33. The bar chart 61 has an upper limit 64 and a lower limit 65. For example, the bar chart 61 represents a particular pertinent ventilator parameter 66, such as its ventilation performance, overall performance, or transpulmonary performance. The upper limit 64 or lower limit 65 indicates the maximum or minimum permissible value for the parameter 66, thereby indicating a risk zone for the parameter 66 to the operator 90. At the same time, more important display data 62, 65, such as dead volume or respiratory rate, can be displayed above the upper limit 64 and lower limit 65. The upper limit 64 and lower limit 65 can be determined based on the ventilated patient 75, and the parameter 66 can be animated accordingly.
