Description

Technical Field

[0001] The present invention relates to a method and related device for generating respiratory data. Background Art

[0002] Exhalation refers to the active expulsion of air by the relaxation of the diaphragm and the contraction of the intercostal muscles. The pressure exerted on the alveoli releases the air contained in the alveoli.

[0003] However, certain diseases such as cystic fibrosis, chronic obstructive pulmonary disease, and asthma can affect these muscles, even to the extent of causing respiratory failure. It has also been observed that patients cured of Covid19 may experience respiratory failure within a few months after recovery.

[0004] A training device is known in which a subject inhales into a tube connected to a channel in which a ball is placed, and the ball will be lifted by the subject's exhalation. However, this type of system is monotonous and may become boring for patients. Even some studies have shown that the observation rate for patients with chronic diseases such as asthma is very low. Therefore, there is a risk that patients cannot follow the treatment correctly and thus cannot obtain the best results.

[0005] The known document WO2018 / 011358 enables athletes to perform measurement work through a mouthpiece and analyze their respiratory ability, enabling the measurement of the exhaled air pressure and the analysis of this pressure. One drawback of this system is that it is not suitable for non-athletes who quickly get bored with repetitive movements and cannot fully control their breathing, especially in terms of the rhythm and reactivity of the respiratory muscles.

[0006] Therefore, the present invention aims to provide a method and related device that allow users to monitor and improve their respiratory performance. Summary of the Invention

[0007] According to one aspect, the present invention relates to a method for generating user respiratory data.

[0008] The method includes:

[0009] · Generating a multimedia instruction with a timestamp through software of an electronic terminal and transmitting the multimedia instruction to the user through a transmission device;

[0010] · Measuring the air pressure in the fluid exhalation chamber of a respiratory unit for receiving the amount of air exhaled and / or inhaled by the user;

[0011] · Generating a respiratory instruction with a timestamp based on the measured air pressure;

[0012] · Detecting an interaction on a tactile interface (for example, a tactile interface integrated with the respiratory unit);

[0013] ·Generate a haptic indication with a timestamp based on the detected interaction;

[0014] ·Receive a breathing indication and a haptic indication by a calculator of the electronic terminal;

[0015] ·Generate breathing data quantifying the user's breathing performance based on the relevance of the haptic indication and the breathing indication to the multimedia instruction.

[0016] One advantage of the present invention is to generate data that makes it possible to measure the user's breathing progress. Another advantage is to encourage the user to synchronize his interaction movements with his exhalation and / or inhalation.

[0017] In one embodiment, the breathing indication is generated based on:

[0018] ·The maximum or average air pressure value measured within a predetermined time interval, and / or

[0019] ·The time when the air pressure value is higher than a predetermined threshold.

[0020] In one embodiment, the haptic indication further includes the identification of the interaction device where the interaction has been detected; and / or the duration of the interaction; and / or the intensity of the interaction. One advantage is that each haptic interface (or "key" on the unit) can be distinguished. In this way, the user can obtain different effects according to the key he presses, and / or the multimedia instruction may include haptic interaction instructions on the key. In one embodiment, the device includes a joystick adapted to be held in one hand of the user and includes the haptic interface on its surface.

[0021] In one embodiment, the multimedia instruction with a timestamp includes a breathing instruction and / or an interaction instruction.

[0022] One advantage of the presence of the haptic instruction is that it allows the user to pay less attention to his breathing, thus obtaining results that are more representative of the user's ability. On the other hand, the haptic instruction allows the user to set the synchrony that can be used to synchronize his exhalation.

[0023] In one embodiment, the breathing instruction includes a start date, and the breathing data is generated based on the start date and the timestamp of the breathing indication.

[0024] In one embodiment, the breathing instruction includes a value to be achieved. In one embodiment, the breathing indication includes the measured maximum or average pressure. In one embodiment, the breathing data is generated based on the value to be achieved and the measured maximum or average pressure.

[0025] In one embodiment, the interaction instruction includes a start date, and the breathing data is generated based on the start date and the timestamp of the haptic indication.

[0026] In one embodiment, the interaction instruction includes a target identifier, and the breathing data is generated based on the target identifier and the identifier indicated by the haptic. One advantage is the ability to integrate the reaction time and / or synchronization ability of the user's breathing muscles in the breathing data. This advantage is to give an interaction instruction for a specific key and detect whether the correct key is actually pressed.

[0027] In one embodiment, the method further includes a prior physiological measurement of the user, and includes issuing an alarm if the physiological measurement exceeds a predetermined value range. One advantage of this embodiment is to prevent the user from performing breathing exercises if the condition does not permit or there is a risk.

[0028] In one embodiment, the physiological measurement includes the heart rate and / or blood oxygen saturation measured by a reflective oximeter provided on the surface of the breathing unit. One advantage is to prevent the user from using the device when his blood oxygen level is too low. In fact, breathing movements tend to lower this value, so there is a risk if the user's ratio is already too low before the start of the exercise. Another advantage is to monitor the user during the breathing exercise. Then, the user can continue training with confidence because he knows that an alarm will be issued if his physiological measurement value is too low.

[0029] In one embodiment, the method further includes determining a score based on the breathing instruction and the haptic instruction or based on the breathing data. One advantage is to obtain reproducible data so that the user's score can be monitored over a long period of time to see his progress. Another benefit is that it can be compared with other users.

[0030] In one embodiment, the method further includes displaying an image of an interactive video game on a display, the interactive video game including controllable elements based on the breathing instruction and the haptic instruction or based on the breathing data. One advantage is the ability to convert the instruction into a video game, making the user less bored when doing the exercise. Therefore, one advantage is to improve the user's compliance in treating his chronic respiratory disease.

[0031] According to another aspect, the present invention relates to a device for generating user breathing data, including a breathing unit. The breathing unit includes an air pressure sensor for measuring the air pressure of the user's exhalation and / or inhalation, and at least two haptic interfaces integrated with the breathing unit.

[0032] According to an alternative aspect, the present invention relates to a device for generating user breathing data, including a breathing unit and at least two haptic interfaces. The breathing unit includes an air pressure sensor for measuring the air pressure of the user's exhalation and / or inhalation. The haptic interface can be provided on a remote joystick.

[0033] According to one or another aspect, the device further includes an electronic terminal, and the electronic terminal includes a calculator. In one embodiment, the calculator is adapted to execute the steps of the method according to the present invention. Then the device includes connecting means for connecting the breathing unit and / or the tactile interface to the electronic terminal. An advantage is that it allows the user to interact with the tactile interface provided on the same object as he breathes. Thus, the user only has one object to hold. An advantage is that it facilitates exercises including synchronous breathing instructions and tactile interactions. The advantage of the remote tactile interface of the breathing unit is that it can reproduce the feeling of a joystick for the user. Thus, another advantage is that it is easier to interact without having to raise the arm to hold the breathing unit.

[0034] In one embodiment, the device includes two joysticks which are not integral with each other, and each joystick includes at least one tactile interface as described above. An advantage is that it is possible to hold one joystick in each hand, and thus it is easier to interact while maintaining the flexibility of the whole arm.

[0035] In one embodiment, the device includes communication means connected to the electronic terminal for transmitting data to the user. An advantage is that the electronic terminal is installed in a remote device connected to the breathing unit and / or the tactile interface.

[0036] In one embodiment, the device includes a lighting device designed to emit light according to breathing instructions and / or tactile instructions.

[0037] In one embodiment, the device includes a reflective oximeter on the surface of the breathing unit. An advantage is that it is possible to measure the oxygen content in the user's blood before or during the exercise by simply pressing a finger on a part of the surface of the breathing unit. The user does not need to perform any specific action for this type of measurement and does not need to equip himself with a bulky additional device.

[0038] In one embodiment, the device includes a display device. The display device is connected to the electronic terminal and / or the calculator. An advantage is that it is possible to display multimedia instructions to the user during the exercise. Another advantage is that it is possible to display scores or interactive video games to the user.

[0039] In one embodiment, the breathing unit further includes at least one motion sensor for measuring the tilt angle of the breathing unit. The motion sensor is preferably connected to the electronic terminal. The motion sensor makes it possible to provide angular motion information of the breathing unit. The advantage is that angular displacement instructions are integrated into the multimedia instructions to distract the user's attention, thereby training his breathing without the user having to focus all his attention on his breathing.

[0040] In one embodiment, the electronic terminal is configured to determine the orientation of the breathing unit based on data provided by a motion sensor. The electronic terminal may include a display of a predetermined target orientation of the breathing unit, and generate and display an indication based on the orientation of the breathing unit relative to the predetermined target orientation. One advantage is to guide the user to understand the orientation of the breathing unit. For example, the device can be used for administering a therapeutic agent that requires a specific orientation of the breathing unit. In another example, the device can be advantageously used to simulate the administration of a therapeutic agent.

[0051] Figure 6 These are perspective views of three different detachable mouthpieces.

[0052] Figure 7 This is a perspective view of an embodiment of a breathing unit with a mouthpiece installed.

[0053] Figure 8 This is according to Figure 7 a perspective view of a breathing unit without a mouthpiece. The breathing unit includes two outlets for cooperating with means for connecting a mouthpiece. The outlets are fluidly connected to a pressure sensor in the breathing unit. One outlet is intended to be connected to the fluid outlet of the mouthpiece for receiving the mouth of the subject, while the other outlet is intended to be connected to the fluid outlet of the mouthpiece to measure the atmospheric pressure when the user places the mouthpiece in his mouth. Detailed Description

[0054] In this description, "inhalation" is the breathing phase in which the atmosphere enters the lungs. "Exhalation" is the breathing phase in which the atmosphere is expelled from the lungs.

[0055] According to a first aspect, the present invention relates to a device 100 for generating respiratory data. The device 100 for generating respiratory data includes a breathing unit 1. The device 100 may further include an electronic terminal 10.

[0056] A first exemplary breathing unit 1 is shown in Figure 2A . The breathing unit 1 includes a fluid exhalation chamber 8 for receiving the air exhaled by the user.

[0057] The breathing unit 1 may include a mouthpiece 5 in which the user can place his lips to inhale and exhale.

[0058] The mouthpiece 5 includes an opening 52. The mouthpiece 5 includes a cavity 53 such that the opening 52 can be fluidly connected to the body of the breathing unit, in particular to the fluid exhalation chamber 8. In this regard, the mouthpiece includes a connecting device 51 connected to an additional connecting device 83 of the breathing unit.

[0059] "Fluid chamber" refers to any structure capable of containing a certain volume of fluid, which is used to measure the pressure in such a structure. In this regard, the fluid chamber may include a part of a fluid channel.

[0060] Preferably, the mouthpiece 5 is detachably attached to the breathing unit.

[0061] The fluid exhalation chamber 8 includes a fluid opening 81. The fluid opening can be in fluid communication with the cavity 53 of the mouthpiece 5. Then the air of inhalation and exhalation from the user passes through this fluid chamber, generating a vacuum and an overpressure respectively that can be measured by an air pressure sensor.

[0062] One advantage is that the mouthpiece 5 is detachable, enabling the mouthpiece to be cleaned without cleaning the entire breathing unit. Another advantage is that the mouthpiece 5 can be replaced to adapt the mouthpiece to the user. Then, the breathing unit is suitable for use by different people with different oral anatomies, especially by changing the size of the detachable mouthpiece 5. Another advantage is the ability to adapt the mouthpiece to a specific exercise, for example, in the case where the user should exhale with the lips contracted.

[0063] In an embodiment (not shown), the fluid exhalation chamber 8 includes a membrane. The membrane is preferably airtight and makes it possible to create a sealed isolation between the pressure sensor 82 and the external environment. The membrane is deformable so as to transmit the air pressure to which the membrane is subjected to the air in the fluid passage 87 existing between the membrane and the air pressure sensor 82. One advantage is that the fluid passage and the air pressure sensor are protected from contamination by dust, dirt, bacteria or viruses.

[0064] The membrane can be provided at the fluid opening 81 or at the fluid passage 87, or generally between the fluid opening 81 and the air pressure sensor 82. The membrane can be made of a plastic material, such as an elastic material.

[0065] When the fluid exhalation chamber 8 includes a membrane, the air pressure sensor makes it possible to measure the air pressure exhaled and / or inhaled by the user in the fluid exhalation chamber. In fact, due to the deformation of the membrane, the part of the fluid chamber between the air pressure sensor and the membrane includes a pressure that varies according to the air pressure exhaled and / or inhaled by the user.

[0066] The fluid exhalation chamber 8 is formed by a wall 83. At least one wall has an air outlet hole 84. The air outlet hole 84 is in fluid communication with the outside of the breathing unit 1 and allows gas to escape from the fluid chamber 8. Preferably, the air outlet hole 84 is arranged transversely or substantially perpendicular to the direction in which the gas passes through the opening 81 in the fluid chamber. Preferably, the cross-section of the outlet hole 84 is smaller than the cross-section of the opening 81 of the fluid exhalation chamber 8. This arrangement makes it possible to create a resistance to the air discharge and to generate a pressure in the fluid exhalation chamber 8 that can be measured, preferably during inhalation and / or exhalation of the user. The air outlet hole 84 can also be designed to allow the air in the fluid passage between the opening of the mouthpiece 52 and the sensor 82 to escape. This advantageously allows the user more time to breathe without generating an exhalation overpressure in the fluid passage.

[0067] In an embodiment, asFigure 7 As shown, the air outlet hole 84 is provided in the mouthpiece 5.

[0068] The breathing unit 1 enables the measurement of the air pressure in the fluid exhalation chamber 8. In this regard, the breathing unit 1 may include an air pressure sensor 82.

[0069] The air pressure sensor is preferably composed of or includes a pressure-sensitive element to determine the actual pressure applied to the sensor and convert this information into an output signal. The pressure sensor is connected to an electronic terminal such that the output signal is transmitted to the electronic terminal.

[0070] The pressure sensor may include a pressure-sensitive element to which a pressure gauge is pasted or sprayed. The pressure-sensitive element may include a diaphragm.

[0071] The air pressure sensor may also include a capacitive pressure sensor or a piezoresistive pressure sensor well-known to those skilled in the art.

[0072] The air pressure sensor 82 may be provided against the wall 83 of the fluid exhalation chamber 8. The pressure sensor 82 may be provided in a blind channel 87 that is in fluid communication with the fluid exhalation chamber 8.

[0073] In Figure 2B In the second example shown, the mouthpiece 5 includes the fluid exhalation chamber 8. The mouthpiece 5 has an inlet 52 through which the user can inhale and exhale. The mouthpiece is detachable. The fluid exhalation 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 provided on two opposite walls 83 of the fluid exhalation chamber 8.

[0074] The advantage of placing the fluid exhalation chamber 8 in the detachable mouthpiece 5 is that it facilitates the cleaning of the chamber and prevents the accumulation of moisture.

[0075] In this embodiment, the breathing unit 1 includes a recess designed to receive the detachable mouthpiece 5. In this case, the breathing unit 1 includes a device 88 that mates with the detachable mouthpiece 5. Preferably, the detachable mouthpiece 5 includes additional mating means 54 for detachably attaching to the breathing unit 1.

[0076] The breathing unit 1 may include a blind (i.e., non-open) fluid channel 87 that extends from the inlet 86. In this case, the fluid channel is in fluid communication with the fluid exhalation chamber 8. The fluid channel includes an air pressure sensor 82. The air pressure sensor 82 enables the measurement of the air pressure exhaled by the user. The air pressure sensor 82 enables the measurement of the air pressure in the fluid exhalation chamber 8. When the mouthpiece is mounted on the breathing unit 1, the inlet 86 of the fluid channel 87 is arranged to mate with the third fluid outlet opening 85 of the fluid exhalation chamber of the mouthpiece.

[0077] One advantage of the fluid passage 87 is that it protects the air pressure sensor 82, especially when handling the breathing unit during removal of the mouthpiece.

[0078] The outlet opening 84 allows the exhaled air to escape from the fluid exhalation chamber 8 to the outside of the unit 1. Then, the user can continuously exhale or inhale into the fluid exhalation chamber 8. The purpose of this outlet opening 84 is also to create a resistance to air entering and leaving the fluid chamber during inhalation and exhalation, respectively. This resistance advantageously makes it possible to increase the pressure caused by inhalation and / or exhalation in the fluid exhalation chamber.

[0079] In one embodiment, the breathing unit 1 includes an atmospheric fluid chamber 7. Such an atmospheric fluid chamber makes it possible to measure the atmospheric pressure. One advantage is the ability to provide a measured value of the atmospheric pressure as a baseline for the air pressure measurement in the fluid exhalation chamber 8. The atmospheric fluid chamber 7 includes a second air pressure sensor 72 and an air outlet hole 71 that is in fluid communication with the external environment, optionally through the passage of the mouthpiece 5. The second air pressure sensor 72 can include a differential pressure sensor. The second air pressure sensor 72 is thus advantageously protected. In Figure 8 In one embodiment shown, the air outlet hole 71 is arranged to be connected to the open fluid passage of the mouthpiece. One advantage is that the atmospheric fluid chamber 7 is enlarged to improve the accuracy of the measured atmospheric pressure.

[0080] The mouthpiece 5 can include a second opening, a second cavity, and second connecting means for connection to the hole 71 of the atmospheric fluid chamber 7.

[0081] In one embodiment, the atmospheric fluid chamber 7 also includes a membrane, such as the membrane described for the fluid exhalation chamber 8.

[0082] In one embodiment, the mouthpiece 5 includes a spirometer. The air outlet hole 71 can be connected to the exhalation pressure of the user in the spirometer. The spirometer can include a hollow cylinder through which the airflow exhaled or inhaled by the user passes. In this embodiment, the air outlet hole 71 is connected to the first part of the cylinder, and the opening 81 of the fluid exhalation chamber is connected to a second part different from the first part of the cylinder. Thus, each air pressure sensor measures the pressure relative to the air flow rate exhaled and / or inhaled in different parts of the cylinder.

[0083] The electronic terminal can be configured to generate an indication showing the individual vital capacity based on the pressure difference measured by the two air pressure sensors 82, 72.

[0084] In one embodiment, the device 100 includes a plurality of tactile interfaces 2. Preferably, the tactile interfaces 2 make it possible to detect user interaction. In a first embodiment, the tactile interface 2 includes keys. In Figure 3A key is shown in the cross-sectional view. The key 2 includes a movable lid 21 that can be pressed by a user's finger. When pressed, the lid 21 moves along a predetermined path, preferably in a direction substantially perpendicular to the surface 26 of the breathing unit 1. Moving the lid 21 causes the connecting member 24 to move.

[0085] The key 2 may include a switch whose state changes according to the movement of the connecting member 24. Preferably, the switch is connected to the printed circuit 6.

[0086] As Figure 3 shown, the connector 26 may include at least one connection track 25. When the connector 26 is at the end of its travel, the connection track 25 is arranged to contact the connection track 22 of the printed circuit 6. Detecting the contact between the two connection tracks 25, 22 allows detection of the interaction on the user interface.

[0087] In other embodiments, the interface may include a tactile surface, and the hole includes means for detecting user interaction on the interface. The interface 2 may also include a pressure sensor to measure the pressure applied by the user during the interaction.

[0088] In one embodiment, the tactile interface 2 is integrated with the breathing unit 1. In this case, the tactile interface 2 is located on the same object where the user exhales and the air pressure is measured. One advantage is that it allows the user to exhale and interact with the tactile interface simultaneously.

[0089] In Figure 1 and 7 the example shown, the breathing unit 1 has a flute shape, and the tactile interfaces 2 are arranged in the same way as the keys of a flute. The breathing unit 1 may include four tactile interfaces 2. The four tactile interfaces may be aligned with each other and with the openings 52, 81 of the fluid exhalation chamber. In other embodiments not shown, the breathing unit 1 may have the form of a saxophone or any other type of musical instrument or wind instrument. In all cases, the tactile interfaces 2 are arranged such that they can be touched by the user's fingers in the same way as a wind instrument.

[0090] Preferably, the tactile interface 2 is located on the surface 26 of the breathing unit 1 such that when the user breathes into the mouthpiece 5, different fingers of the user can contact each tactile interface.

[0091] In an alternative embodiment (not shown), the haptic interface is provided on the surface of an object different from the breathing unit. For example, the haptic interface can be provided on the surface of a joystick designed to be held by the user's hand. The device can include two joysticks, each joystick including at least one haptic interface. The haptic interface can be connected to the electronic terminal via a wired or wireless connection, such as Bluetooth, Wi-Fi, or any other wireless connection known to those skilled in the art.

[0092] Each haptic interface 2 can be connected to a printed circuit 6. Then the device 100 is configured to detect interactions on the haptic interface.

[0093] Preferably, the breathing unit 1 can include a lighting device 23. The lighting device 23 can include a light bulb or a light-emitting diode. The breathing unit can be designed such that the lighting device 23 emits light when an interaction is detected on the interface. Preferably, each lighting device 23 is associated with an interface, and the unit is configured such that each lighting device 23 emits light when an interaction is detected on the associated haptic interface 2. In Figure 3 the embodiment shown, the connecting member 24 is light-transmissive. The connecting member 24 advantageously allows the light emitted by the lighting device 23 to pass through. In one embodiment, the device is configured to cause the lighting device to emit light to transmit information to the user, such as low battery level, connection status between the breathing unit 1 and the electronic terminal 10.

[0094] In one embodiment, the breathing unit 1 includes a device 3 for measuring the user's physiological data. Preferably, the physiological data measuring device 3 is a haptic device. The measuring device 3 can be provided on the surface 26 of the breathing unit. The measuring device 3 is preferably integrated with the surface 26 of the breathing unit.

[0095] The measuring device preferably includes a reflectance photoplethysmograph or a reflectance colorimetric oximeter. A photoplethysmograph or a colorimetric oximeter can be used on the capillary layer to quantify the oxygen saturation of hemoglobin and measure the user's heart rate.

[0096] Preferably, the measuring device 3 includes a light emitter and a sensor that receives light reflected by the user, preferably reflected by the user's finger. Thus, the emitter and the sensor are located on the same surface. One advantage of capturing reflected light instead of transmitted light is that the user does not have to perform any specific actions specific to oxygen saturation measurement. The user simply places his finger on the measuring device 3 to obtain physiological measurements. Advantageously, the user can use the device 100 to make measurements during exercise without having to perform operations that may limit exercise or impede the freedom of his finger by clamping the device.

[0097] In Figure 1 、 2AIn the examples shown in FIGS. 2A and 2B, the breathing unit 1 includes four tactile interfaces and includes a measuring device 3 disposed between two of the tactile interfaces.

[0098] In another example, not shown, the measuring device 3 can be placed at any position on the breathing unit 1 that can be touched by the user's finger when the user holds the breathing unit. For example, the measuring device can be provided on one side, opposite to the side including the tactile interface 2. An advantage is that the user can place their thumb on the tactile interface. Advantageously, due to its larger contact area and larger volume, physiological data measurements made by the user's thumb are more reliable and / or accurate.

[0099] In one embodiment, the breathing unit includes a pad 4. The pad is provided near the tactile interface 2. The pad 4 is preferably arranged to receive the user's finger.

[0100] One advantage of the pad 4 is that it can hold the breathing unit in a balanced manner by at least one finger of the user. In fact, in the example of a flute-shaped breathing unit, the two thumbs of the user are placed under the unit. The middle finger, index finger, and ring finger are placed on top of the breathing unit. The pad 4 advantageously allows the user to hold the breathing unit 1 in balance, especially without the risk of incorrect interaction with the tactile interface 2.

[0101] The pad 4 can include a rough or adhesive surface, such as a surface including silicone or a spiked surface. The breathing unit 1 can include two or more pads 4, which advantageously allows for the placement of fingers that are not used for interacting with the tactile interface 2 and / or the measuring device 3.

[0102] The device 100 according to the invention includes an electronic terminal 10. The electronic terminal 10 can receive and process data from various sensors of the measuring unit, such as air pressure sensors 82, 72, the tactile interface 2, and / or the measuring device 3.

[0103] The electronic terminal 10 can be integrated into the measuring unit. In Figure 1 In another example shown, the electronic terminal 10 is embedded in a remote device. In this example, the breathing unit 1 includes a transmitter 9. The transmitter 9 is connected to the various sensors 82, 72, 3, 2 of the breathing unit 1 to receive and send the measured or detected data to the electronic terminal 10 of the remote device. In Figure 2A and 2B In the example shown, the breathing unit 1 includes a printed circuit 6 connected to different sensors 82, 72, 2, 3, and the printed circuit 6 is connected to the transmitter 9. Advantageously, the printed circuit 6 is capable of retrieving and / or processing different measurement and detection data for transmission to the transmitter 9 and / or the electronic terminal 10.

[0104] The electronic terminal can also be configured to receive information specific to the breathing unit 1. The device can be configured such that the electronic terminal can receive information about the battery status of the breathing unit or about the humidity level in the fluid exhalation chamber 8.

[0105] The device 100 can also include a communication device 11. The communication device 11 makes it possible to transmit information to the user. The communication device 11 can include a sound transmitter or a display. The electronic terminal 10 is connected to the communication device 11. The communication device 11 makes it possible to transmit to the user the variables measured by the device 100 from the measurements of the air pressure sensor 82 and / or from the touch interaction data detected by the tactile interface 2. In one embodiment, the communication device includes the lighting device 23 of the breathing unit 1.

[0106] The electronic terminal 10 includes a calculator CALC.

[0107] The electronic terminal 10 can include a memory, preferably a non-transitory memory.

[0108] The electronic terminal 10 advantageously enables the received signals to be processed.

[0109] According to one embodiment, the device 100 includes at least two different detachable mouthpieces 5. The different mouthpieces are significantly different in the surface and shape of the cross-section of their openings 52. The following refers to Figure 6 Three types of mouthpieces are described.

[0110] The first detachable mouthpiece A includes an opening 52 with a cylindrical or substantially cylindrical cross-section. The first mouthpiece advantageously makes it possible to maximize the air flow. In fact, such a section makes it possible to increase the air flow exhaled by the user. One advantage is that constants such as vital capacity, maximum expiratory volume per second, and maximum expiratory flow can be measured by the device. Preferably, when used for adults, the cross-sectional size of the opening of the first detachable mouthpiece A is between 900 mm 2 and 600 mm 2 or, when used for children, the cross-sectional size is between 300 mm 2 and 420 mm 2 between. The opening part of the first detachable mouthpiece A can include an opening, and the diameter of the opening part is between 35 - 25 mm or between 25 - 20 mm.

[0111] In one embodiment, the first detachable mouthpiece A includes an edge designed to receive by pressing the head (not shown) of a disposable mouthpiece. The head of the mouthpiece can include a cylindrical part designed to cooperate with the first detachable mouthpiece A. The head of the mouthpiece can include any shape that allows it to cooperate with the detachable mouthpiece 5.

[0112] The second detachable mouthpiece B includes an opening with a preferably oval or substantially oval cross-section. Preferably, the cross-section of the opening of the second mouthpiece B is between 150 mm 2 and 550 mm 2 or between 300 mm 2 and 400 mm 2 . The second mouthpiece advantageously allows the user to perform long and deep exhalation exercises.

[0113] The third detachable mouthpiece C allows the user to perform exercises to promote the excretion of mucus from the user's lungs. The third mouthpiece includes an oscillating expiratory positive pressure device. When the user exhales, the oscillating expiratory positive pressure device generates resistance pulses. This resistance forms a positive pressure in the user's lungs, helping to keep the respiratory tract unobstructed. In addition, the pulses create vibrations within the respiratory tract, helping to dilute and remove mucus that is too thick or too sticky to be removed solely by pressure. The combined action of the pressure and vibration causes the mucus to move towards the central respiratory tract and then be expelled from here by coughing.

[0114] Thus, the device 100 according to an embodiment of the present invention includes at least one or at least two of the first detachable mouthpiece, the second detachable mouthpiece, and the third detachable mouthpiece.

[0115] Preferably, the device includes a breathing unit and three detachable mouthpieces: a first mouthpiece, a second mouthpiece, and a third mouthpiece. Of course, other types of detachable mouthpieces can be designed and integrated into the device 100, especially for performing specific exercises.

[0116] The advantage of these three detachable mouthpieces 5 is that three usage functions can be obtained by using a single breathing unit 1 by simply replacing the detachable mouthpiece 5. Thus, the breathing unit 1 can be used for a constant measurement function with the first detachable mouthpiece A, a training function with different types of exhalation (prolonged exhalation, rapid exhalation) with the second detachable mouthpiece B, and an expectoration assistance function (also known as salt inhalation therapy) with the third detachable mouthpiece C.

[0117] In one embodiment, the device 100 includes an identifier for the detachable mouthpiece 5 connected to the breathing unit.

[0118] The identifier may include an electronic device, such as a detachable mouthpiece connection track detector.

[0119] The identifier may include magnetic detection means. When each detachable mouthpiece includes a magnetic device, these magnetic detection means enable the detection of the mouthpiece connected to the breathing unit, the magnetic field strength and / or position of which varies depending on the mouthpiece.

[0120] The recognizer may include a light detection device for marking a detachable mouthpiece. The recognizer may include a mechanical detection device. For example, the mouthpiece may include a specific mechanical insert designed to cooperate with the breathing unit so that it can be recognized or identified.

[0121] A second aspect of the invention relates to a method for generating user breathing data S.

[0122] The method preferably includes using the device 100 according to the first aspect of the invention.

[0123] The method is intended to generate breathing data S that quantifies the user's breathing performance. The breathing data S is generated based on the measurement SI made by the air pressure sensor 82 of the fluid exhalation chamber 8.

[0124] The method for generating breathing data S is intended to send a multimedia instruction Cm to the user and measure the user's response to the instruction. Then, the breathing data S is generated from the response. The user's response may include an exhalation that can be measured by the air pressure sensor 82 of the fluid exhalation chamber 8.

[0125] An advantage is that it allows the transmission of the multimedia instruction Cm to the user and the generation of the breathing data S based on the correlation between the multimedia instruction Cm and the user response.

[0126] In one embodiment of the invention, the response may include an interaction SI with one or more tactile interfaces 2 of the breathing unit 1. Then, the user is prompted to perform an exercise that combines exhalation and / or finger movement commands. An advantage is that, for example, the regularity of the breathing rhythm can be assisted by complementary or similar rhythm beats of the fingers.

[0127] The following refers to Figure 5 Describe a method for performing the method according to the invention.

[0128] In one embodiment, the method includes a physiological measurement MES_G of the user before generating the breathing data and / or before measuring the air pressure SC exhaled by the user.

[0129] The method may include generating GEN_G and / or issuing a warning message Kg when the measured physiological value is within or outside a predetermined value range.

[0130] The physiological measurement SL preferably includes a measurement of the user's heart rate. The physiological measurement SL may also include the user's hemoglobin oxygen saturation value.

[0131] One advantage of this pre - measurement is that it allows the user to operate the device safely. In fact, a user suffering from respiratory failure may experience a drop in oxygen in the blood during breathing exercises. Thus, this measurement makes it possible to detect before the exercise whether the oxygen saturation level in the user's hemoglobin is high enough to enable 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 with the device. The warning message Kg can include a visual message, for example, via the lighting device 23 of the breathing unit. The warning message Kg can include an audible message. The warning message Kg can include a message displayed on the display. The warning message Kg can include a sensory message, such as the vibration of a vibrator provided in the breathing unit 1. The warning message Kg can cause the breathing device to stop or prevent its use.

[0132] The physiological measurement SL is preferably measured with the measuring device 3 of the above - mentioned breathing unit 1. One advantage is that it allows the user to perform this measurement simply by placing a finger on the surface 26 of the measuring unit. Then, the user does not have to move his hand between performing the physiological measurement and using the breathing unit.

[0133] In one embodiment of the present invention, the method includes stopping the method or the device when the measured physiological value SL is within or outside a first predetermined value range. In one embodiment, the method includes generating respiratory data S when the measured physiological value is within or outside a second predetermined value range.

[0134] The method for generating respiratory data includes generating a CO multimedia instruction Cm. The generated multimedia instruction Cm is transmitted to the user. The multimedia instruction Cm can be transmitted to the user via the display 11 or in an audible manner.

[0135] The multimedia instruction Cm can include an exhalation instruction.

[0136] The generation CO of the multimedia instruction Cm is timestamped, or the transmission of the multimedia instruction is timestamped. Timestamping the transmission of the multimedia instruction advantageously allows comparison of the transmission date of the instruction and the user's response. For example, such a comparison makes it possible to calculate the difference between the target date and the date when the user performs the action (tactile and / or breathing) requested by the multimedia instruction.

[0137] Optionally, the multimedia instruction Cm can be generated by the software of the electronic terminal 10.

[0138] The method for generating respiratory data includes measuring the air pressure SC of the air exhaled and / or inhaled by the user MEP_P. The measurement MEP_P of the air pressure can be measured by the air pressure sensor 82 of the exhalation chamber 8 of the breathing unit 1 according to the first aspect of the present invention.

[0139] Measurements of the air pressure sensor 82 of the fluid exhalation chamber 8 can be recorded on a data storage medium, especially in real time.

[0140] In one embodiment of the invention, the measurement of the air pressure can include measuring the air in the fluid exhalation chamber during inhalation and / or exhalation of the user.

[0141] The method for generating respiratory data includes generating a GEN_P respiratory indication Kp.

[0142] The respiratory indication Kp is generated based on the measured air pressure SC in the fluid exhalation chamber 8.

[0143] The respiratory indication Kp is timestamped. The method can include the step of associating the respiratory indication with a date. This "date" refers to the date and time. The purpose of the timestamp is to record the moment when the measurement and / or generation of the respiratory indication is performed.

[0144] The respiratory indication Kp can be generated based on the exhalation length and can be generated based on the maximum pressure within a given time period.

[0145] In one embodiment, the method further includes measuring the atmospheric pressure. This measurement is preferably performed by the air pressure sensor 72 of the atmospheric fluid chamber 7 of the breathing unit 1 according to the first aspect of the invention. Measuring the atmospheric pressure advantageously makes it possible to use it as a reference for the air pressure measured in the fluid exhalation chamber. The measurement of the air pressure SC in the fluid exhalation chamber is independent of the atmospheric pressure.

[0146] The respiratory indication Kp can be generated based on the air pressure SC measured in the fluid exhalation chamber and based on the measured atmospheric pressure.

[0147] The method for generating respiratory data can include detecting DET an interaction SI on the tactile interface of the breathing unit 1. The interaction is detected when the user interacts with at least one tactile interface 2 of the breathing unit, for example, by touching or pressing at least one tactile interface 2 with a finger.

[0148] The tactile indication Ki is generated GEN_P by or based on the detection of the interaction. For example, when the user presses a button on the breathing unit, 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 undergone the interaction.

[0149] The tactile indication Ki can include the identification of the interface where the interaction is detected, such as the identification of the button where the user's pressure is detected. The tactile indication Ki includes a timestamp of the detection of the interaction. The indication can include the 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.

[0150] The tactile indication Ki and / or the breathing indication Kp are transmitted to the calculator CALC of the electronic terminal 10. As previously mentioned, the electronic terminal 10 can be arranged in the breathing unit 1 or in a remote device.

[0151] From these two timestamped indications and the timestamped multimedia instruction Cm, breathing data S is generated. The breathing data S is preferably generated by the calculator CALC.

[0152] The breathing data S is generated based on the correlation of the two metrics Ki, Kp with the multimedia instruction Cm. The breathing data S makes it possible to quantify the user's breathing performance. For example, the breathing data S can include a score 34, the value of which increases when the tactile indication Ki and the breathing indication Kp match the multimedia instruction Cm.

[0153] In a first example, the multimedia instruction Cm can include a breathing instruction and a synchronized tactile interaction instruction. The breathing instruction includes a continuous exhalation instruction at least on a given date, and preferably in a synchronized manner, for example at a given rhythm. The interaction instruction includes instructions for interacting with the tactile interface on at least one given date, preferably in a synchronized manner. The breathing instruction can also include a dated inhalation instruction. The instructions can be transmitted to the user and include one or more target exhalation dates and one or more target tactile interaction dates and / or multiple target inhalation dates. The instructions can also include at least one tactile interface identifier associated with each target tactile interaction date. Preferably, the target dates are synchronized in order to follow a rhythm or a piece of music.

[0154] The generated breathing indication Kp and tactile indication Ki are then compared with the multimedia instruction Cm. Notably, the timestamps of the breathing indication Kp and the tactile indication Ki are compared with the target dates included in the multimedia instruction Cm. The breathing data S can be generated based on the difference between the timestamps of the above-mentioned indications and the target dates of the multimedia instruction. In one embodiment, the identifier of the tactile target date is compared with the identifier of the generated tactile indication Ki, and the breathing data is generated based on this comparison.

[0155] On the one hand, the presence of the tactile instruction enables the user to pay less attention to his breathing, thus obtaining results that are more representative of the user's capabilities. On the other hand, the tactile instruction allows the user to set the synchronization for synchronizing his exhalation.

[0156] In a second example, the multimedia instruction Cm can include moving a controllable element of an interactive video game displayed on the display 11. The controllable element 33 can be controlled by the user's exhalation and / or interaction on the tactile interface. In Figure 4In one example shown, the transmission of the multimedia instruction Cm includes the display of the controllable element 33 of the interactive video game (here a boat). The boat can be controlled to move straight forward by the user's exhalation, and to jump by tactile interaction, and vice versa. The exhalation bar 31 allows the user to observe the change of the breathing indication Kp. The breathing indication Kp makes it possible to propel the controllable element 33. The multimedia instruction Cm can also include the display of obstacles, such as seagull droppings 32 and rocks 37. Then the multimedia instruction Cm can include instructions to avoid the obstacles 32, 37 by moving forward and jumping. The multimedia instruction Cm can include instructions to interact with at least one tactile interface when the controllable element 33 approaches or touches an obstacle, such as picking up an object.

[0157] Then, breathing data S is generated according to the number of obstacles avoided, the time to complete the route, and / or the distance traveled by the controllable element 33 in the interactive game within a given time. The score 34 and the timer 36 can be displayed.

[0158] In a third example, the multimedia instruction Cm includes the display of a route including a starting point and an ending point and a controllable element moving from the starting point to the ending point. The movement of the controllable element is activated by the breathing indication, and the direction of movement can be controlled by the tactile indication, or vice versa. Thus, the breathing data depends on the time taken to complete the route and / or the number of obstacles avoided.

[0159] In another example, the multimedia instruction Cm includes a breathing instruction that includes the target exhalation time and / or the target exhalation force that the user is to achieve. The breathing instruction can include a plurality of target exhalation times to be achieved within a predetermined time. The interaction instruction can include a target interaction simultaneous with the target exhalation. Then, the breathing data S can be generated according to the breathing indication Kp. The breathing data S can be generated to correspond to a breathing constant, such as vital capacity, maximum exhalation volume per second, or peak expiratory flow rate.

[0160] In one embodiment, the device 100 includes a device connected to a network. The device 100 can be designed to compare the generated breathing data with the breathing data of other users in real time or using historical usage data. In one embodiment, the device can generate multimedia instructions and transmit them to the devices of each user via the network. Thus, each user can receive the same multimedia instructions, allowing for a "multiplayer" type of use.

[0161] In one embodiment, the device 100 includes a plurality of breathing units 1 and an electronic terminal 10. The electronic terminal is designed to be connected to at least two breathing units 1 simultaneously to generate breathing data S for each breathing unit 1 simultaneously. One advantage is that the device can be used with friends or caregivers in a multi - person mode.

[0162] In one embodiment of the present invention, the method includes a prior step of detecting the detachable mouthpiece 5. Thus, the type of the detachable mouthpiece 5 connected to the breathing unit 1 can be determined. A multimedia instruction Cm can be generated according to the type of the detachable mouthpiece 5 that has been detected as connected to the breathing unit 1. In an alternative embodiment, the device interface allows the user to select the types A, B, and C of the detachable mouthpiece.

[0163] The breathing data S can be stored in the memory of the electronic terminal, transmitted to the network and / or transmitted to a third-party device. Thus, one advantage is the ability to monitor the user's progress according to the recovery period or treatment period. Another advantage is to transmit the data to the user's relatives and / or caregivers involved in the user's breathing tracking or to make the data accessible to them. The breathing data can include the user's breathing constants. The breathing data S can be presented in the form of historical data, charts, or scrolling tables. The transmission to the network or a third party can be performed by the user's activation, for example, by sending an email from the electronic terminal 10 or by direct transmission. The breathing data can be encrypted or protected with a security key or password.

[0164] Preferably, the electronic terminal 10 of the device 100 includes a calculator CALC, which is adapted or designed to perform the steps of the method for generating breathing data according to the present invention.

[0165] According to another aspect, the present invention relates to a computer program product, including instructions that cause the device 100 according to the present invention to perform the steps of the method according to the present invention.

[0166] The electronic terminal 10 can include a carrier readable by the calculator CALC or a computer, and the computer program is stored on the carrier. The carrier can include a non-transitory memory.

[0167] According to another aspect, the present invention relates to a medium having recorded thereon the computer program.

[0168] By using a tactile interface other than breathing, the device and method according to the present invention allow for more types of interactive exercises, thus making it possible to divert the user's attention from his breathing and help the user achieve the target exhalation rhythm by playing the same rhythm simultaneously or a rhythm associated with one or more fingers. The associated rhythm refers to a rhythm having the same beat as the exhalation rhythm.

[0169] Therefore, the device is capable of causing the user to perform exhalation training in terms of vital capacity (amount of exhaled air, exhalation power) and muscle reactivity (reaction speed, ability to maintain rhythm) according to different multimedia instructions.

[0170] According to another aspect, the breathing unit includes means capable of determining the orientation of the breathing unit.

[0171] In this regard, the breathing unit may include a motion sensor. The motion sensor may consist of one or more accelerometers to calculate the linear acceleration along one axis. Preferably, the motion sensor includes three accelerometers to calculate the linear acceleration along three orthogonal axes. In one embodiment, the motion sensor includes one or more gyroscopes to calculate the rotational speed or angular velocity based on angles such as roll angle, pitch angle, or yaw angle. Preferably, the motion sensor includes three gyroscopes to calculate the rotational angle or angular velocity along three orthogonal axes.

[0172] In one embodiment, the motion sensor includes an inertial unit. The inertial unit preferably includes three accelerometers to calculate the linear acceleration along three orthogonal axes, and three gyroscopes to calculate the angular acceleration along three orthogonal axes. The motion sensor is preferably integrated in the breathing unit of the device.

[0173] The motion sensor is connected to an electronic terminal to transmit the measured data to the electronic terminal.

[0174] The device is designed to generate the orientation of the breathing unit. The device is preferably configured to generate and display an orientation indication. The orientation indication can be calculated based on the orientation of the breathing unit and / or a predetermined target orientation. Such an indication can be displayed on a display or can be displayed by an LED device. A directional device is preferably used to specify the tilt angle of the breathing unit relative to the earth's baseline horizontal plane.

[0175] The advantages of this mode are described below.

[0176] The breathing unit can be used in support of taking a medicament for the treatment of a respiratory disease. The medicament may include a drug powder, a drug gas, or a drug atomized solution. The user must inhale the medicament according to a specific orientation.

[0177] In one embodiment, the device is configured to send a message to the user when the orientation of the breathing unit is within a predetermined target angle range.

[0178] In some cases, the user must inhale the medicament according to a specific orientation. In one embodiment, the device is configured to send a message to the user when the inhalation force measured by the breathing unit is within a predetermined target range.

[0179] The message may include an audible alarm and / or a color change of the LED and / or generating a vibration of the breathing unit and / or displaying a message on a display.

[0180] Then, it advantageously helps the user to perform the inhalation of the medicament in an appropriate orientation and / or inhalation force.

[0181] In one embodiment, the mouthpiece may include a container for receiving or storing such a therapeutic agent to be inhaled by a user breathing through the opening of the mouthpiece.

[0182] In another example, the breathing unit is used to reproduce the taking of such a therapeutic agent. In this case, the breathing unit provides the user with a training means for simulating the taking of such a therapeutic agent, in particular providing training on the orientation of the device and the inhalation force applied for correct administration of the therapeutic agent.
