Description

[Technical Field]

[0001] The present invention relates to a method and associated apparatus for generating respiratory data. [Background technology]

[0002] Exhalation is the voluntary release of air by relaxation of the diaphragm and contraction of the intercostal muscles. This pressure on the alveoli expels the air contained in them.

[0003] However, certain diseases, such as cystic fibrosis, chronic obstructive pulmonary disease, and asthma, can affect these muscles to the point that they cause respiratory failure, and patients who have recovered from COVID-19 have been observed to experience respiratory failure for several months after recovery.

[0004] A known training device involves subjects breathing into a tube connected to a channel containing a ball, which is then lifted by the subject's exhalation. However, this type of system can be monotonous and boring for patients. However, several studies have shown that patients with chronic diseases such as asthma have low adherence rates. Such systems pose a risk of patients not adhering correctly to treatment and achieving suboptimal results.

[0005] Patent document 1 is also known for measuring the exhaled air pressure and analyzing the athlete's breathing ability by working with a mouthpiece. The drawback of this system is that it is not suitable for non-athletes who quickly tire of repetitive exercises and do not have complete control over their breathing, especially in terms of the rhythm and reactivity of their respiratory muscles.

[0006] [Patent Document 1] International Publication No. 2018 / 011358 Summary of the Invention [Problem to be solved by the invention]

[0007] SUMMARY OF THE INVENTION Accordingly, the present invention aims to provide a method and associated device that allows a user to monitor and improve their breathing capacity. [Means for solving the problem]

[0008] According to one aspect, the present invention relates to a method for generating respiratory data for a user. The above method is generating time-stamped multimedia instructions via software in the electronic terminal and transmitting the multimedia instructions to the user via a transmission means; measuring the air pressure in a fluid expiratory chamber of the respirator that receives a volume of air exhaled and / or inhaled by the user; generating time-stamped respiration metrics as a function of the measured air pressure; Detecting interactions on a haptic interface, for example a haptic interface integrated with a respiratory system; generating time-stamped tactile metrics as a function of the detected interactions; Receiving respiratory and tactile indicators via a computer on an electronic terminal; Respiratory data is generated that quantifies the user's respiratory capacity as a function of the correlation of the tactile and respiratory indices with the multimedia commands.

[0009] One advantage of the present invention is that it generates data that allows the progress of a user's breathing to be measured, another advantage is that it encourages the user to synchronize their interactive movements with exhalation and / or inhalation.

[0010] In one embodiment, the respirometer comprises: The maximum or average pressure measured over a given time interval, and / or The time that the air pressure value remains above a given threshold is generated as a function of

[0011] In one embodiment, the tactile indication further comprises an identifier of the interaction means with which the interaction was detected, and / or the duration of the interaction, and / or the intensity of the interaction. One advantage is to distinguish between each tactile interface (or "key" of the unit). In this way, the user can obtain different effects as a function of the key the user presses, and / or the multimedia instructions can comprise tactile interaction instructions on the keys. In one embodiment, the device comprises a joystick adapted to be held in one hand of the user, and comprises said tactile interface on its surface.

[0012] In one embodiment, the time-stamped multimedia instructions include breathing instructions and / or interaction instructions.

[0013] One advantage of the presence of haptic commands is that they allow the user to focus less on breathing, resulting in results that are more representative of the user's capabilities. On the other hand, haptic commands allow for a synchronicity that the user can use to synchronize with exhalation.

[0014] In one embodiment, the breathing instructions include a start date, and the breathing data is generated as a function of the start date and a timestamp of the breathing index.

[0015] In one embodiment, the breathing command includes a value to be reached. In one embodiment, the breathing indicator includes a measured maximum or mean pressure. In one embodiment, the breathing data is generated as a function of the value to be reached and the measured maximum or mean pressure.

[0016] In one embodiment, the interaction instructions include a start date, and the respiration data is generated as a function of the start date and a timestamp of the tactile indicator.

[0017] In one embodiment, the interaction instructions include a target identifier, and the respiratory data is generated as a function of the target identifier and the identifier of the tactile indicator. One advantage is that the reaction time and / or synchronization ability of the user's respiratory muscles can be integrated into the respiratory data. The advantage is to provide an interaction instruction with a specific key and detect whether the correct key has actually been pressed.

[0018] In one embodiment, the method further includes prior physiological measurements of the user and issuing an alert if the physiological measurements are outside of a predefined range of values. One advantage of this embodiment is that it prevents the user from performing breathing exercises if conditions do not allow it or if there is a risk.

[0019] In one embodiment, the physiological measurements include heart rate and / or blood oxygen saturation, measured by a reflectance oximeter placed on the surface of the respiratory system. One advantage is that it prevents the user from using the device if their blood oxygen level is too low. In fact, respiratory activity tends to lower this value, so there is a risk if the user's heart rate is already too low before starting to exercise. Another advantage is that it monitors the user during exercise. This allows the user to continue training with confidence, knowing that an alert will be issued if the physiological measurements are too low.

[0020] In one embodiment, the method further includes determining a score as a function of the respiratory and tactile indicators, or as a function of the respiratory data. One advantage is that reproducible data is obtained, allowing a user's score to be monitored over time to determine progress. Another advantage is that it can be compared with other users.

[0021] In one embodiment, the method further includes displaying on the display an image of an interactive video game including controllable elements as a function of the respiratory indicator and the tactile indicator, or as a function of the respiratory data. One advantage is that by providing instructions in the video game, the user becomes less bored during exercise. Thus, one advantage is improving user compliance with treatment for chronic respiratory disorders.

[0022] According to another aspect, the present invention relates to an apparatus for generating respiratory data of a user, the apparatus comprising a ventilator including an air pressure sensor for measuring the air pressure exhaled and / or inhaled by the user, and at least two tactile interfaces integrated with the ventilator.

[0023] According to an alternative aspect, the present invention relates to an apparatus for generating respiratory data of a user, comprising a ventilator and at least two tactile interfaces, the ventilator including an air pressure sensor for measuring the air pressure exhaled and / or inhaled by the user, the tactile interfaces being arranged on a remote joystick.

[0024] The device according to one or more aspects also includes an electronic terminal equipped with a calculator. In one embodiment, the calculator is adapted to execute the steps of the method according to the invention. The device then includes connection means for connecting the ventilator and / or the haptic interface to the electronic terminal. One advantage is that the user can interact with the haptic interface located on the same object that they are breathing into. Thus, the user only needs to hold one object. One advantage is that it facilitates simultaneous breathing commands and haptic interaction. One advantage of a remote haptic interface on the ventilator is that it can reproduce the sensation of a joystick for the user. Another advantage is that the user does not need to raise their arm to hold the ventilator, making interaction easier.

[0025] In one embodiment, the device includes two disjointed joysticks, each including at least one haptic interface as described above. One advantage is that one joystick can be held in each hand, allowing for easier manipulation while maintaining full arm movement.

[0026] In one embodiment, the device comprises communication means connected to an electronic terminal for transmitting data to the user. One advantage is that the electronic terminal is mounted on a remote device connected to the ventilator and / or the haptic interface.

[0027] In one embodiment, the device comprises light emitting means designed to illuminate as a function of the respiratory and / or tactile indicators.

[0028] In one embodiment, the device includes a reflective oximeter on the surface of the respirator. One advantage is that the user can measure the oxygen level in their blood before or during exercise by simply pressing a portion of the respirator's surface with their finger. The user does not need to perform any specific action to perform this type of measurement, nor does the user need to carry any bulky additional equipment.

[0029] In one embodiment, the device includes a display means connected to an electronic terminal or computer. One advantage is that it can display multimedia instructions to the user while exercising. Another advantage is that it can display scores or interactive video games to the user.

[0030] In one embodiment, the ventilator further includes at least one motion sensor for measuring the tilt angle of the ventilator. The motion sensor is preferably connected to an electronic terminal. The motion sensor can provide angular motion information of the ventilator. A first advantage is that the angular displacement instructions that distract the user are integrated into the multimedia instructions so that the user can train their breathing without paying full attention to breathing.

[0031] In one embodiment, the electronic terminal is configured to determine the orientation of the ventilator from data provided by the motion sensor. The electronic terminal can include a display of a predetermined target orientation of the ventilator and the generation and display of an indicator as a function of the orientation of the ventilator relative to the predetermined target orientation. One advantage is that it guides the user in the orientation of the ventilator. For example, the device can be used for administering a therapeutic agent that requires a specific orientation of the ventilator. In another example, the device can be advantageously used to simulate the administration of a therapeutic agent.

[0032] According to another aspect, the invention relates to a computer program product comprising instructions for directing an apparatus according to the invention to perform the steps of the method according to the invention.

[0033] According to one aspect, the invention relates to a computer program product comprising instructions for causing a computer to carry out the method according to the invention when the program is executed by the computer. The computer program product may comprise instructions for causing a computer of an electronic terminal of a device according to the invention to carry out the method according to the invention when the program is executed by the computer.

One outlet is intended to be connected to a fluid outlet of a mouthpiece for receiving the subject's mouth, and the other outlet is intended to be connected to a fluid outlet of a mouthpiece for measuring atmospheric pressure when a user inserts the mouthpiece into their mouth. DETAILED DESCRIPTION OF THE INVENTION

[0037] As used herein, "inhalation" is the phase of breathing in which air enters the lungs. "Exhalation" is the phase of breathing in which air leaves the lungs.

[0038] According to a first aspect, the invention relates to an apparatus 100 for generating respiratory data. The apparatus 100 for generating respiratory data comprises a respirator 1. The apparatus 100 may also comprise an electronic terminal 10.

[0039] A first exemplary respirator 1 is shown in Figure 2A. The respirator 1 includes a fluid exhalation chamber 8 that receives air exhaled by a user.

[0040] The respirator 1 may include a mouthpiece 5 against which the user can place their lips to breathe in and out.

[0041] The mouthpiece 5 has an opening 52. The mouthpiece 5 comprises a cavity 53 that makes it possible to fluidly connect the opening 52 to the body of the respirator, in particular to the fluid exhalation chamber 8. In this respect, the mouthpiece comprises connection means 51 to additional connection means 83 of the respirator.

[0042] A "fluid chamber" refers to any structure capable of containing a volume of fluid for the purpose of measuring pressure in such structure. In this regard, a fluid chamber can include a portion of a fluid channel.

[0043] The mouthpiece 5 is preferably attached to the respirator in a removable manner.

[0044] The fluid exhalation chamber 8 includes a fluid opening 81. The fluid opening may be in fluid communication with the cavity 53 of the mouthpiece 5. Air from the user's inhalation and exhalation then passes through the fluid chamber, creating a vacuum and overpressure, respectively, that can be measured by an air pressure sensor.

[0045] One advantage is that the mouthpiece 5 can be removed and cleaned without cleaning the entire respirator. Another advantage is that the mouthpiece 5 can be replaced, allowing the mouthpiece to be adapted to the user. The respirator can then be adapted to be used by different people with different oral anatomies, particularly by changing the size of the removable mouthpiece 5. Another advantage is that the mouthpiece can be adapted to specific movements, such as exhaling with your lips pinched.

[0046] In one embodiment not shown, the fluid exhalation chamber 8 includes a membrane. The membrane is preferably airtight, allowing for a leak-tight gap between the pressure sensor 82 and the external environment. The membrane is deformable so as to transmit the air pressure experienced by the membrane to the air present in the fluid channel 87 between the membrane and the air pressure sensor 82. One advantage is that the fluid channel and the air pressure sensor are protected from contamination by dust, dirt, bacteria, or viruses.

[0047] The membrane may be disposed at the fluid opening 81 or at the fluid channel 87, or generally between the fluid opening 81 and the air pressure sensor 82. The membrane may be made from a plastic material, such as an elastomeric material.

[0048] If the fluid exhalation chamber 8 includes a membrane, the air pressure sensor can measure the air pressure exhaled and / or inhaled by the user in the fluid exhalation chamber. Indeed, the portion of the fluid chamber between the air pressure sensor and the membrane contains a pressure that varies as a function of the air pressure exhaled and / or inhaled by the user, thanks to deformation of the membrane.

[0049] The fluid expiratory chamber 8 is formed by walls 83. At least one of the walls has an air outlet hole 84, which is in fluid communication with the exterior of the respirator 1 and allows gas to escape from the fluid chamber 8. The air outlet hole 84 is preferably positioned transversely or substantially perpendicular to the direction of gas in the fluid chamber through the opening 81. The cross section of the outlet hole 84 is preferably smaller than the cross section of the opening 81 of the fluid expiratory chamber 8. This positioning allows for creating a resistance to air exit, preferably creating a measurable pressure in the fluid expiratory chamber 8 during the user's inhalation and / or exhalation. The air outlet hole 84 can also be designed to allow air in the fluid channel between the opening of the mouthpiece 52 and the sensor 82 to escape. This has the advantage of allowing the user to hold their breath for a longer period of time without creating exhalation overpressure in the fluid channel.

[0050] In one embodiment, the air outlet holes 84 are located in the mouthpiece 5 as shown in FIG.

[0051] The respirator 1 allows the air pressure in the fluid exhalation chamber 8 to be measured. The respirator 1 may include an air pressure sensor 82 in this regard.

[0052] The air pressure sensor preferably consists of or comprises a pressure sensitive element for determining the actual pressure applied to the sensor and converting this information into an output signal, which is connected to an electronic terminal and transmitted to the electronic terminal.

[0053] The pressure sensor may include a pressure sensitive element to which the pressure gauge is attached or sprayed, and the pressure sensitive element may include a diaphragm.

[0054] The air pressure sensor may also include a capacitive or piezoresistive pressure sensor, which are well known to those skilled in the art.

[0055] The air pressure sensor 82 may be positioned against a wall 83 of the fluid expiratory chamber 8. The pressure sensor 82 may be positioned in a blind channel 87 that is in fluid communication with the liquid expiratory chamber 8.

[0056] In a second example shown in FIG. 2B, the mouthpiece 5 includes a fluid exhalation chamber 8. The mouthpiece 5 has an inhalation port 52 through which the user can inhale and exhale. The mouthpiece is removable. The fluid exhaust chamber 8 includes a second fluid outlet opening 84 and a third opening 85. Preferably, the second opening 84 and the third opening 85 are located on two opposing walls 83 of the fluid exhaust chamber 8.

[0057] One advantage of locating the fluid exhalation chamber 8 in the removable mouthpiece 5 is that it makes cleaning of the chamber easier and prevents moisture buildup.

[0058] In this embodiment, the respirator 1 comprises a recess designed to receive the removable mouthpiece 5. In this case, the respirator 1 comprises means 88 for coupling with the removable mouthpiece 5. The removable mouthpiece 5 preferably comprises additional means 54 for removable attachment to the respirator 1.

[0059] The respirator 1 may include a blind (i.e., non-open) fluid channel 87 extending from the inlet 86. The fluid channel, in this case, is in fluid continuity with the fluid expiratory chamber 8. The fluid channel includes an air pressure sensor 82. The air pressure sensor 82 allows the air pressure of the air exhaled by the user to be measured. The air pressure sensor 82 allows the air pressure within the fluid expiratory chamber 8 to be measured. The inlet 86 of the fluid channel 87 is positioned to align with a third fluid outlet opening 85 of the fluid expiratory chamber of the mouthpiece when the mouthpiece is attached to the respirator 1.

[0060] One advantage of the fluid channel 87 is that it protects the air pressure sensor 82 when handling the respirator, especially when the mouthpiece is removed.

[0061] The outlet opening 84 allows exhaled air to escape from the fluid expiratory chamber 8 to the outside of the respirator 1. The user can then exhale and inhale continuously into the fluid expiratory chamber 8. The purpose of this outlet opening 84 is also to create a resistance to the air entering and leaving the fluid chamber during inhalation and exhalation, respectively. This resistance has the advantage that it can increase the pressure in the fluid expiratory chamber due to inhalation and / or exhalation.

[0062] In one embodiment, the respirator 1 includes an atmospheric fluid chamber 7. This atmospheric fluid chamber allows for the measurement of atmospheric pressure. One advantage is that it can provide an atmospheric pressure measurement that serves as a baseline for measuring the air pressure in the fluid exhalation chamber 8. The atmospheric fluid chamber 7 includes a second air pressure sensor 72 and an exit hole 71 that is in fluid communication with the external environment, optionally via a channel in the mouthpiece 5. The second air pressure sensor 72 can include a differential pressure sensor. This advantageously protects the second air pressure sensor 72. In one embodiment, shown in FIG. 8, the exit hole 71 is positioned to connect to an open fluid channel in the mouthpiece. One advantage is that the atmospheric fluid chamber 7 is enlarged, improving the accuracy of the measured atmospheric pressure.

[0063] The mouthpiece 5 may include a second opening, a second cavity, and second connection means for connecting with the hole 71 in the atmospheric fluid chamber 7 . In one embodiment, the atmospheric fluid chamber 7 also includes a membrane as described for the fluid exhalation chamber 8.

[0064] In one embodiment, the mouthpiece 5 includes a spirometer. The outlet hole 71 can be connected to the user's exhalation pressure within the spirometer. The spirometer can include a hollow cylinder through which the user's exhaled and inhaled air flows. In this embodiment, the outlet hole 71 is connected to a first surface of the cylinder, and the fluid exhaust chamber opening 81 is connected to a second surface of the cylinder that is different from the first surface. In this manner, each air pressure sensor measures the pressure versus the flow rate of exhaled and / or inhaled air at a different surface of the cylinder.

[0065] The electronic terminal may be configured to generate an index indicative of the individual's lung capacity as a function of the difference in pressure measured by the two air pressure sensors 82,72.

[0066] In one embodiment, the device 100 comprises a plurality of tactile interfaces 2. Preferentially, the tactile interfaces 2 make it possible to detect user actions. In a first embodiment, the tactile interfaces 2 comprise buttons. Figure 3 shows a cross-sectional view of a button. The buttons 2 comprise movable caps 21 that can be pressed by the user's finger. When pressed, the caps 21 move along a predetermined path, preferably in a direction substantially perpendicular to the surface 26 of the respirator 1. Moving the caps 21 can move the connecting pieces 24.

[0067] The button 2 may comprise a switch whose state is changed as a function of the movement of the connector 24. Preferably, the switch is connected to the printed circuit 6.

[0068] 3, the connector 26 can include at least one connection track 25. The connection track 25 is arranged to contact a connection track 22 of the printed circuit 6 when the connector 26 is terminated. Contact between the two connection tracks 25, 22 can be detected to detect an interaction on the user interface.

[0069] In other embodiments, the interface may include a tactile surface, a hole containing a means for detecting a user's interaction on the interface. The interface 2 may also include a pressure sensor to measure the pressure applied by the user during interaction.

[0070] In one embodiment, the haptic interface 2 is integral with the respiratory apparatus 1. In this case, the haptic interface 2 is on the same object on which the user exhales and on which the air pressure is measured. One advantage is that the user can simultaneously exhale and interact with the haptic interface.

[0071] In the examples of Figures 1 and 7, the ventilator 1 is shaped like a flute, with the tactile interfaces 2 arranged in the same way as the keys on a flute are arranged. The ventilator 1 can include four tactile interfaces 2. The four tactile interfaces can be aligned with each other and with the openings 52, 81 of the fluid exhalation chamber. In other embodiments not shown, the ventilator 1 can have the form of a saxophone or other type of musical instrument or wind instrument. In either case, the tactile interfaces 2 are arranged to be touched by the fingers in the same way as on a wind instrument.

[0072] Preferably, the tactile interface 2 is located on the surface 26 of the respirator 1 so that the user can touch each of the mouthpieces 5 with different fingers when breathing in.

[0073] In another embodiment not shown, the haptic interface is located on a surface of an object other than the respirator. For example, the haptic interface may be located on a surface of a joystick designed to be held in the user's hand. The device may include two joysticks, each with at least one haptic interface. The haptic interface may be connected to an electronic device via a wired connection or a wireless connection, such as Bluetooth, Wi-Fi, or other wireless connection known to those skilled in the art.

[0074] Each haptic interface 2 can be connected to a printed circuit 6. The device 100 is then set up to detect interactions on the haptic interfaces.

[0075] The ventilator 1 preferably comprises light emitting means 23. The light emitting means 23 may comprise a light bulb or a light emitting diode. The ventilator may be designed such that the light emitting means 23 illuminate when an interaction is detected on the interface. Preferably, each light emitting means 23 is associated with an interface, and the ventilator is configured such that each light emitting means 23 illuminates when an interaction is detected with the associated tactile interface 2. In the embodiment shown in Figure 3, the connectors 24 are transparent to light. Advantageously, the connectors 24 allow light emitted by the light emitting elements 23 to pass through. In one embodiment, the device is configured to illuminate the light emitting means to communicate information to the user, such as low battery, the status of the connection between the ventilator 1 and the electronic terminal 10, etc.

[0076] In one embodiment, the respirator 1 comprises means for measuring physiological data 3 of the user. The physiological data measuring means 3 are preferably tactile means. The measuring device 3 can be placed on the surface 26 of the respirator. The measuring device 3 is preferably integral with the surface 26 of the respirator.

[0077] Preferably, the measuring means comprises a reflectance photoplethysmograph or a reflectance colorimetric oximeter, which is used to quantify oxygen saturation of hemoglobin at the capillary level and measure the user's heart rate.

[0078] The measuring means 3 preferably comprises a light emitter and a sensor for light reflected by the user, preferably by the user's finger. Therefore, the light emitter and the sensor are located on the same surface. One advantage of capturing reflected light rather than transmitted light is that the user does not need to perform any specific actions specific to measuring oxygen saturation. The user can obtain physiological measurements by simply placing their finger on the measuring means 3. The user can advantageously use the device 100 and perform measurements while exercising, without having to perform any actions that may limit their movement and without having to restrict the freedom of their finger with a pinch device.

[0079] In the example shown in Figures 1, 2A and 2B, the respirator 1 comprises four tactile interfaces and a measuring means 3 arranged between two of the tactile interfaces.

[0080] In another example not shown, the measuring means 3 may be placed anywhere on the ventilator 1 that the user can touch with their fingers when holding the ventilator. For example, the measuring means may be placed on the side opposite to the side with the tactile interface 2. One advantage is that the user can place their thumb on the tactile interface. Thanks to the large contact area and volume, measuring physiological data with the user's thumb has the advantage of being more reliable and / or accurate.

[0081] In one embodiment, the ventilator includes a pad 4. The pad is positioned near the tactile interface 2. The pad 4 is preferably positioned to rest the user's fingers.

[0082] One advantage of the pad 4 is that the user balances the ventilator with at least one finger. Indeed, in the example of the flute-shaped ventilator, the user's two thumbs are placed under the ventilator, while the middle, index, and ring fingers are placed on top of the ventilator. The pad 4 advantageously allows the user to maintain balance on the ventilator 1 without the risk of accidentally interacting with the haptic interface 2 in particular.

[0083] The pads 4 may comprise a rough or sticky surface, such as a silicone or spur-containing surface. The respirator 1 may comprise two or more pads 4, which advantageously allows for resting fingers not used for interfacing with the tactile interface 2 and / or the measuring means 3.

[0084] The device 100 according to the invention comprises an electronic terminal 10. The electronic terminal 10 makes it possible to receive and process data from the various sensors of the measuring device, such as the air pressure sensors 82, 72, the tactile interface 2 and / or the measuring means 3.

[0085] The electronic terminal 10 may be integrated into the measuring device. In another example, shown in Figure 1, the electronic terminal 10 is embedded in a remote device. In this example, the ventilator 1 comprises a transmitter 9. The transmitter 9 is connected to the various sensors 82, 72, 3, 2 of the ventilator 1 and transmits and receives measured or detected data to the electronic terminal 10 of the remote device. In the example shown in Figures 2A and 2B, the ventilator 1 comprises a printed circuit 6 connected to the different sensors 82, 72, 2, 3, which is connected to the transmitter 9. The printed circuit 6 advantageously allows the retrieval and / or processing of the different measured values ​​and their detection for transmission to the transmitter 9 and / or the electronic terminal 10.

[0086] The electronic terminal may also be configured to receive information specific to the ventilator 1. The device may also be configured to allow the electronic terminal to receive information regarding the battery status of the ventilator or the humidity level of the fluid exhalation chamber 8.

[0087] The device 100 may also comprise communication means 11, which allow transmitting information to the user. The communication means 11 may comprise an acoustic transmitter or a display. The electronic terminal 10 is connected to said communication means 11. The communication means 11 allow transmitting to the user variables measured by the device 100 from the measurements of the air pressure sensor 82 detected by the haptic interface 2 and / or from touch interactions. In one embodiment, the communication means comprise the light emitting means 23 of the respirator 1.

[0088] The electronic terminal 10 is configured with a computer CALC. The electronic terminal 10 may include a memory, preferably a non-transitory memory. The electronic terminal 10 is advantageously capable of processing the signals it receives.

[0089] According to one embodiment, the device 100 comprises at least two different removable mouthpieces 5. The different mouthpieces differ significantly in the surface and cross-sectional shape of their openings 52. The three types of mouthpieces are described below with reference to Figure 6.

[0090] The first removable mouthpiece A includes an opening 52 of cylindrical or substantially cylindrical cross section. The first mouthpiece has the advantage of being able to maximize airflow. Indeed, such a cross section allows the user to increase the flow rate of exhaled air. One advantage is that the device can measure constants such as vital capacity, maximum expiratory volume in one second, and maximum expiratory flow rate. The cross section of the opening of the first removable mouthpiece A is 900 mm for an adult. 2 from 600mm 2 , 300mm for children 2 From 420mm 2 The cross section of the opening of the first removable mouthpiece A may include an opening having a cross section diameter comprised between 35-25 mm or 25-20 mm.

[0091] In one embodiment, the first removable mouthpiece A includes a periphery designed to receive a single-use mouthpiece head (not shown) by pushing it in. The mouthpiece head can include a cylindrical portion designed to interface with the first removable mouthpiece A. The mouthpiece head can include any shape that can interface with the removable mouthpiece 5.

[0092] The second removable mouthpiece B preferably comprises an opening of oval or substantially oval cross section. The cross section of the opening of the second mouthpiece B is 150 mm 2 Over 550mm 2 Less than or equal to 300mm 2 Over 400mm 2 It is desirable that: The second mouthpiece has the advantage that it allows the user to perform a long, deep exhalation exercise.

[0093] The third, removable mouthpiece C allows the user to perform exercises that promote the expulsion of mucus from the lungs. The third mouthpiece includes an oscillating positive airway pressure device. The oscillating positive airway pressure device creates pulses of resistance when the user exhales. This resistance builds positive pressure in the user's lungs, helping to keep the airways open. Additionally, the pulses create vibrations within the airways that help thin and loosen mucus that is too thick or viscous to be dislodged by pressure alone. The combination of pressure and vibrations moves mucus toward the central airways, from where it can be expelled by coughing.

[0094] Thus, device 100 according to one embodiment of the present invention includes at least one mouthpiece or at least two of first, second and third removable mouthpieces.

[0095] The device preferably includes a respirator and three removable mouthpieces (first, second, and third). Of course, other types of removable mouthpieces may be designed and integrated into device 100 specifically to perform certain tasks.

[0096] One advantage of the three removable mouthpieces 5 is that one respirator 1 can have three different usage functions by simply changing the removable mouthpieces 5. In this way, the respirator 1 can be used for a constant measurement function with the first removable mouthpiece A, a training function with different types of exhalation (extended exhalation, rapid exhalation) with the second removable mouthpiece B, and an expectorant assistance function (also called inhalation therapy) with the third removable mouthpiece C.

[0097] In one embodiment, the device 100 includes an identifier for the removable mouthpiece 5 connected to the respirator.

[0098] The identifier may include electronic means such as a removable mouthpiece-connected track detector.

[0099] The identifier may include magnetic detection means that, if each removable mouthpiece is provided with magnetic means whose magnetic strength and / or position differs for each mouthpiece, allow the detection of the mouthpiece connected to the respirator.

[0100] The identifier may include optical detection of a marker on the removable mouthpiece. The identifier may include mechanical detection. For example, the mouthpiece may include a specific mechanical insert designed to interface with the respirator, allowing it to be recognized or identified.

[0101] A second aspect of the present invention relates to a method for generating respiratory data S of a user. The above method preferably includes the use of an apparatus 100 according to the first aspect of the present invention.

[0102] The method aims to generate respiratory data S that quantify the user's breathing capacity. The respiratory data S is generated as a function of the measurements SI by the air pressure sensor 82 in the fluid expiratory chamber 8.

[0103] The method for generating the respiratory data S involves transmitting a multimedia command Cm to a user and measuring the user's response to the command, from which the respiratory data S is then generated. The user's response may include exhaled air, which may be measured by the air pressure sensor 82 in the fluid exhalation chamber 8.

[0104] One advantage is that it allows for the transmission of multimedia commands Cm to a user and generates respiratory data S as a function of the correlation between the multimedia commands Cm and the user's response.

[0105] In one embodiment of the present invention, the response may include an interaction SI with one or more haptic interfaces 2 of the respiratory unit 1. The user is then prompted to perform an exercise that combines an exhalation command and / or a finger movement command. One advantage is that the regularity of the breathing rhythm can be aided by, for example, a complementary or similar rhythmic beat with the fingers.

[0106] The implementation of the method according to the invention will now be described with reference to FIG. In one embodiment, the method includes a physiological measurement MES_G of the user prior to generating the respiratory data and / or prior to measuring SC the user's exhaled air pressure.

[0107] The method may include generating GEN_G and / or issuing an alert Kg if the measured physiological value is within a predefined range of values ​​or outside a predefined range of values.

[0108] The physiological measurements SL preferably include a measurement of the user's heart rate. The physiological measurements SL may also include the user's hemoglobin oxygen saturation value.

[0109] One advantage of such a pre-measurement is that it allows the user to operate the device safely. Indeed, users suffering from respiratory failure may experience a drop in blood oxygen during breathing exercises. This measurement makes it possible to detect before exercise whether the user's hemoglobin oxygen saturation is high enough for safe exercise. In this case, a warning message Kg can be issued. The warning message Kg is intended to advise the user not to start training using the device. The warning message Kg can, for example, comprise a light message via the light-emitting means 23 of the ventilator. The warning message Kg can also comprise an audible message. The warning message Kg can also comprise a message displayed on the display. The warning message Kg can also comprise a sensory message, for example, a vibration of a vibrator arranged in the ventilator 1. The warning message Kg can stop or block use of the ventilator.

[0110] The physiological measurement SL is preferably taken by the measuring means 3 of the respiratory apparatus 1 described above. One advantage is that the user can take such a measurement by simply placing their finger on the surface 26 of the measuring apparatus, thereby eliminating the need for the user to move their hand between picking up the physiological measurement and using the respiratory apparatus.

[0111] In one embodiment of the invention, the method includes stopping the method or stopping the device if the measured physiological value SL is within or outside a first predefined range of values. In one embodiment, the method includes generating respiration data S if the measured physiological value SL is within or outside a second predefined range of values.

[0112] The method for generating respiratory data includes generating multimedia instructions Cm. The generated multimedia instructions Cm are transmitted to the user. The multimedia instructions Cm can be transmitted to the user via the display 11 or in an audible manner.

[0113] The multimedia storage Cm may contain exhalation instructions. The generation CO of the multimedia command Cm is time-stamped or the transmission of the multimedia command is time-stamped. The time-stamp of the transmission of the multimedia command can advantageously allow a comparison of the transmission date of the command with the user's response. This comparison makes it possible, for example, to calculate the difference between the date on which the user performed the action (touch and / or breath) requested by the multimedia command and the target date.

[0114] The multimedia instructions Cm may optionally be generated via software in the electronic terminal 10 .

[0115] The method for generating respiratory data comprises measuring the air pressure MEP_P of the air exhaled and / or inhaled by the user. The air pressure measurement MEP_P can be measured by an air pressure sensor 82 in the expiratory chamber 8 of the respirator 1 according to the first aspect of the present invention. The measurements of the air pressure sensor 82 of the fluid exhalation chamber 8 may be recorded in a data storage device, particularly in real time.

[0116] In one embodiment of the present invention, the air pressure measurements may include measurements of air in the fluid exhalation chamber during inhalation and / or exhalation of the user.

[0117] The method of generating the respiratory data includes generating a respiratory index Kp GEN_P. The respiratory parameter Kp is generated as a function of the measured air pressure SC in the fluid expiratory chamber 8. The respiratory index Kp is time-stamped. The method can include associating a date with the respiratory index. "Date" means date and time. The purpose of this timestamp is to record the moment when the respiratory index was measured and / or generated. The respiratory index Kp can be generated as a function of the maximum pressure over a period of time and as a function of the length of exhalation.

[0118] In one embodiment, the method also includes measuring atmospheric pressure, preferably by air pressure sensor 72 in the atmospheric fluid chamber 7 of the respirator 1 according to the first aspect of the present invention. The atmospheric pressure measurement has the advantage that it can serve as a reference for the air pressure measured in the fluid expiratory chamber. The measurement of the air pressure SC in the fluid expiratory chamber is independent of atmospheric pressure.

[0119] The respiratory index Kp can be generated as a function of the air pressure SC measured in the fluid expiratory chamber and as a function of the measured atmospheric pressure.

[0120] The method for generating respiratory data may include detecting DET an interaction SI on a tactile interface of the respiratory apparatus 1. The interaction is detected when a user interacts with the at least one tactile interface 2 of the respiratory apparatus, for example by touching the at least one tactile interface 2 or pressing it with a finger.

[0121] The contact index Ki is generated from or as a function of the detection of an interaction GEN_P. For example, when a user presses a button on the ventilator, a signal SI is generated. The generated signal SI is transmitted to components on the printed circuit and / or electronic terminal. The generated signal makes it possible to detect which interface has been interacted with.

[0122] The tactile indicator Ki may include an identifier of the interface on which the interaction was detected, for example, an identifier of the button on which the user's pressure was detected. The tactile indicator Ki may include a timestamp of the detection of the interaction. The indicator may include an intensity of the interaction, for example, the amount of time the user presses the tactile interface 2 or the force with which the user presses the tactile interface 2.

[0123] The tactile index Ki and / or the respiratory index Kp are transmitted to the calculator CALC of the electronic terminal 10. As mentioned above, the electronic terminal 10 may be located in the respiratory apparatus 1 or in a remote device.

[0124] From these two time-stamped indices and the time-stamped multimedia instructions Cm, respiratory data S is generated. The respiratory data S is preferably generated by a computer CALC.

[0125] The respiratory data S is generated as a function of the correlation between the two indices Ki and Kp and the multimedia command Cm. The respiratory data S can quantify the user's breathing ability. For example, the respiratory data S may include a score of 34, whose value increases as the tactile index Ki and the respiratory index Kp comply with the multimedia command Cm.

[0126] In a first example, the multimedia instructions Cm may include breathing instructions and synchronized haptic interaction instructions. The breathing instructions may include continuous exhalation instructions on at least one specified date, preferably in a synchronized manner, e.g., at a specified tempo. The interaction instructions may include interaction instructions with a haptic interface on at least one specified date, preferably in a synchronized manner. The breathing instructions may also include dated inhalation instructions. The instructions are transmitted to the user and may include one or more target exhalation dates and one or more target haptic interaction dates and / or several target inhalation dates. The instructions may also include at least one haptic interface identifier associated with a target date for each haptic interaction. It may be desirable to synchronize the target dates to a tempo or piece of music.

[0127] The generated respiratory Kp and tactile Ki indices are then compared to the multimedia instructions Cm. In particular, the timestamps of the respiratory Kp and tactile Ki indices are compared to the target date included in the multimedia instructions Cm. Respiratory data S is generated as a function of the difference between the timestamps of the indices and the target date of the multimedia instructions. In one embodiment, an identifier for the tactile target date is compared to an identifier for the generated tactile indices K, and respiratory data is generated as a function of this comparison.

[0128] On the other hand, haptic commands allow the user to focus less on breathing, resulting in results that are more representative of the user's capabilities, whereas haptic commands allow the user to set a synchronicity that can be used to synchronize exhalation.

[0129] In a second example, the multimedia instructions Cm consist of moving a controllable element 33 of an interactive video game displayed on the display 11. The controllable element 33 can be controlled by the user's breath and / or interaction on a haptic interface. In one example shown in FIG. 4, the transmission of the multimedia instructions Cm includes displaying a controllable element 33 of the interactive video game (here, a boat). The user can control the boat by exhaling to move it forward in a straight line and by haptic interaction to make the boat jump, or vice versa. The breath bar 31 allows the user to see the fluctuations of the breathing index Kp. The breathing index Kp can then move the controllable element 33 forward. The multimedia instructions Cm can also include displaying obstacles such as seagull droppings 32 and rocks 37. The multimedia instructions Cm can then include an instruction to avoid said obstacles 32, 37 by moving forward and jumping. The multimedia instructions Cm may include instructions to interact with at least one haptic interface when the controllable element 33 is near or in contact with an obstacle, for example to pick up an object.

[0130] Respiratory data S is then generated as a function of the number of obstacles avoided and as a function of the time to complete the route and / or according to the distance traveled by the controllable element 33 in the interactive game within a given time. A score 34 and a timer 36 can be displayed.

[0131] In a third example, the multimedia instructions Cm include a route with a start and an end and a representation of a controllable element to move from the start to the end. The movement of the controllable element is actuated by a breathing indicator and the direction of the movement may be controlled by a tactile indicator or vice versa. The breathing data is then a function of the time taken to complete the route and / or the number of obstacles avoided.

[0132] In another example, the multimedia instructions Cm include breathing instructions including a target expiratory time and / or a target expiratory force that the user should reach. The respiratory indicators may include several target expiratory numbers to be reached within a predefined time. The interaction instructions may include target interactions simultaneously with the target expiratory times. Thereafter, the respiratory data S is generated as a function of the respiratory indicator Kp. The respiratory data S is generated to correspond to respiratory constants such as vital capacity, maximum expiratory volume per second, and peak expiratory flow rate.

[0133] In one embodiment, device 100 includes means for connecting to a network. Device 100 may be designed to compare the generated respiratory data S with the respiratory data of other users, either in real time or using historical usage data. In one embodiment, the device can generate and transmit multimedia instructions over the network to each user's device. Thus, each user can receive the same multimedia instructions, enabling a "multiplayer" type of use.

[0134] In one embodiment, the device 100 includes multiple ventilators 1 and an electronic terminal 10. The electronic terminal is designed to be simultaneously connected to at least two ventilators 1 and to simultaneously generate respiratory data S for each ventilator 1. One advantage is that the device can be used in multiplayer mode with friends or caregivers.

[0135] In one embodiment of the invention, the method includes a preliminary step of detecting a removable mouthpiece 5, thereby determining the type of removable mouthpiece 5 connected to the ventilator 1. The multimedia instructions Cm can be generated as a function of the detected type of removable mouthpiece 5 connected to the ventilator 1. In an alternative embodiment, the device interface allows the user to select the type of removable mouthpiece A, B, C.

[0136] The respiratory data S may be stored in the electronic terminal's memory, transmitted to a network, and / or transmitted to a third party device. One advantage is that the user's progress can be monitored as a function of rehabilitation or treatment duration. Another advantage is that the data may be transmitted to or made accessible to the user's relatives and / or caregivers involved in follow-up of the user's breathing. The respiratory data may include the user's respiratory constants. The respiratory data S may be presented in the form of a history, graph, or rolling table. Transmission to a network or third party may be initiated by the user, such as by sending an email or by direct transfer from the electronic terminal 10. The respiratory data may be encrypted or protected by a security key or password.

[0137] The electronic terminal 10 of the device 100 preferably comprises a calculator CALC adapted or designed to carry out the steps of the method for generating respiratory data according to the invention.

[0138] According to another aspect, the invention relates to a computer program product comprising instructions for directing the device 100 according to the invention to carry out the steps of the method according to the invention.

[0139] The electronic terminal 10 may also be provided with a storage device (support) for storing a computer program that can be read by a computer or a computer, which may include a non-transitory memory.

[0140] According to another aspect, the invention relates to such a medium having the computer program recorded thereon.

[0141] By using a haptic interface in addition to breathing, the device and method according to the present invention allows for more diverse interactive movements, allows the user to divert attention from breathing, and helps the user reach a target expiratory rhythm by simultaneously playing the same related rhythm or rhythms with one or more fingers. Related rhythm means a rhythm that shares the same tempo as the expiratory rhythm.

[0142] In this way, the device allows the user to address exhalation in terms of both lung capacity (expiratory volume, expiratory force) and muscle reactivity (reaction speed, ability to maintain rhythm) as a function of different multimedia commands.

[0143] According to another aspect, the ventilator includes means for making it possible to determine the orientation of the ventilator.

[0144] The ventilator may include a motion sensor in this regard. The motion sensor may consist of one or more accelerometers to calculate linear acceleration along one axis. Preferably, the motion sensor includes three accelerometers to calculate linear acceleration along three orthogonal axes. In one embodiment, the motion sensor includes one or more gyrometers to calculate rotational or angular velocity according to an angle, such as roll, pitch, or heading angle. Preferably, the motion sensor includes three gyrometers to calculate rotational or angular velocity along three orthogonal axes.

[0145] In one embodiment, the motion sensor includes an inertial unit, preferably comprising three accelerometers for calculating linear acceleration along three orthogonal axes and three gyrometers for calculating angular acceleration along three orthogonal axes, and the motion sensor is preferably integrated into the respirator of the device.

[0146] The motion sensor is connected to an electronic terminal and transmits measurement data to the electronic terminal.

[0147] The device is designed to generate an orientation of the ventilator. The device is preferably configured to generate and display an orientation indicator. The orientation indicator may be calculated as a function of the orientation of the ventilator and / or a predetermined target orientation. The display of such an indicator may be displayed on a display or may be generated by an LED on the device. The orientation means is preferably adapted to specify the angle of inclination of the ventilator relative to the horizontal plane of the Earth's baseline.

[0148] The advantages of such a mode are explained below. Ventilators are sometimes used in the context of assisting the user in taking medication to treat respiratory conditions, which may include a drug powder, a drug gas, or a drug aerosol, and which require the user to inhale the medication in a specific direction.

[0149] In one embodiment, the device is configured to send a message to the user when the orientation of the ventilator is within a predetermined target angle range.

[0150] In some cases, the user may need to inhale the medication according to a particular orientation. In one embodiment, the device is configured to send a message to the user when the inhalation force measured by the ventilator is within a predetermined target range.

[0151] The message may include an audible alert and / or a change in color of an LED and / or the generation of a vibration of the ventilator and / or a message displayed on a display.

[0152] The user is then advantageously assisted in inhaling the medication with the proper orientation and / or inhalation force.

[0153] In one embodiment, the mouthpiece may include a reservoir for receiving and storing such a therapeutic agent such that the user breathes in through an opening in the mouthpiece.

[0154] In another example, a ventilator is used to replicate the administration of such a therapeutic drug, in which case the ventilator provides a training tool for the user to simulate the administration of such a therapeutic drug, particularly training regarding the orientation of the device and the inhalation force that must be exerted to properly administer the therapeutic drug.
