Description

Description Title: Inflatable system configured to fit into a support (Technical field. [1] The present invention relates to an inflatable system configured to be inserted into a support, preferably a baby mattress. The invention also relates to a mattress comprising such an inflatable system, and a method of operating said system. [2] The invention relates to the technical field of systems for calming an individual, in particular babies (children, infants, preferably under 3 years old), in particular systems installed in a baby's bed or cradle. State of the art. [3] During rest and sleep phases, the baby benefits from the presence of a parent, which results in a calming of the baby, a calming manifested by a reduction in its respiratory rate and heart rate. Parental presence is expressed through speech, smells, body heat, but also by the transmission of the parent's respiratory movements and heart rate ("kangaroo care" in English). [4] In many of our societies, close contact between the baby and the parent is limited in time, frequently leaving the infant in the care of a third party (nursery, childminder). This can be impactful when the baby is hospitalized in a situation of physical and / or psychological suffering. It could therefore be interesting to be able to actively reproduce certain markers of parental presence in order to contribute to the comfort of the baby. [5] It is also important to note that infant breathing is characterized by the fact that it is primarily abdominal because the main respiratory muscle is the diaphragm while the intercostal muscles are ineffective because they are too underdeveloped. [6] Thus, any mobilization of an infant during sleep phases must be carried out safely, that is to say without lateral mobilization risking causing the baby to tip over. Indeed, the alteration of respiratory function is clearly involved in the pathophysiology of "sudden infant death syndrome". The alteration of respiratory function in infants is caused in particular by the alteration of the freedom of the upper airways which can be a consequence of lateral positioning or ventral decubitus following a turning of the infant. [7] Currently known is document CN 109757923 B. This document describes a mattress configured to monitor parameters (physical, physiological or biometric) of babies comprising several inflatable zones supporting the baby's head and body (also called "airbags" or "air cushions"). The information collected (such as heart and respiratory rates) is that of the baby, so as to check its state of health. The inflation of the air cushions in the different zones allows for adequate repositioning of the baby and limits the risks of apnea. [8] On the other hand, such a system does not allow babies to be calmed, only to be monitored (commonly called "monitoring") to check their state of health. Finally, if this system stabilizes the baby's head, it does not stabilize its body, especially when the inflatable cushion positioned under the body is functional. [9] Also known in the state of the art is document CN 113208353 A. This document describes a baby cradle comprising two inflatable cushions controlled by an electronic card. These two inflatable cushions are inflated and deflated according to a respiratory rate collected from other babies and pre-recorded in the electronic card.

[0010] In practice, this system has limited effectiveness in calming babies. Furthermore, the bed is not specifically adapted to the baby's head and body, which limits its support. Finally, the safety conditions regarding the mobilization of the baby's body are not described, with a potential risk of mobilization on the sides likely to cause respiratory problems by obstructing the upper airway.

[0011] The prior art also includes document CN 110585556 A. This document discloses an inflatable mattress for calming babies. This mattress comprises two zones: a sleeping zone for the body and an inflatable cushion placed at the level of the baby's head, and which inflates and / or deflates according to a respiratory rate deduced, in a relatively complex manner, from the mother's heart rate.

[0012] However, there is only one inflatable cushion located under the baby's head, which in itself represents a danger for the baby because it is likely to move his head and risk hindering his breathing. The baby's body is not held on the mattress at all, which can also represent a danger.

[0013] Document CN 107468000A is also part of the prior art. This document describes a cushion configured to calm the baby. This cushion comprises a layer composed of three inflatable cushions positioned side by side and each simulating a part of the mother's body. Thus, the inflation and deflation of each inflatable cushion will simulate the breathing of an individual. The inflatable cushions are inflated by at least two inflatable units, such as pumps or compressors, controlled by an electronic card.

[0014] First, the data simulating breathing is parameterized and pre-recorded, and is determined arbitrarily. Finally, inflating an airbag under a baby's body is likely to mobilize the body and cause breathing difficulties.

[0015] The invention aims to overcome at least one of the drawbacks of the aforementioned state of the art. More particularly, the invention aims to improve the systems of the aforementioned prior art, such as the calming effect of said system or the safety of the system for the baby.

[0016] The invention also makes it possible to develop an inflatable system adaptable to a bed, a mattress and / or a seat, more particularly to a motor vehicle seat, the bed, mattress or seat being particularly suitable for supporting the baby, and optimizing its positioning. Presentation of the invention.

[0017] In general, the invention is particularly suitable for a young subject (i.e., whose age is preferably less than three years) which may be a human or an animal, such as a baby or, more preferably, an infant. The inflatable system according to the invention comprises inflatable zones making it possible to reproduce the breathing and heartbeat of a third subject, preferably a relative of the baby, such as its father or mother.

[0018] This invention is intended to provide comfort firstly for the baby, preferably an infant, by the perception of a respiratory rate and / or a heart rate which is known to him, such as, for example, those of one of his two parents. Said respiratory and / or heart rates are captured in an original way and control the inflatable system by a specific electronic pilot.

[0019] The invention relates to the field of active comfort care by applying an inflation technique preferably integrated into a physical support, such as a cradle, a bed, a cushion, and preferably being a mattress. Furthermore, the present invention allows a specific evaluation of the baby's state of comfort thanks to measurements of biometric, physical or physiological data, said measurements being made possible thanks to the specific ergonomics of the system, in particular thanks to measurement sensors for example. The specific evaluation is ensured by comparing reference biometric, physical or physiological measurements of the baby with the biometric, physical or physiological measurements of the baby obtained during and / or after application of the reproduction of the respiratory and / or cardiac frequencies of the parent.

[0020] Finally, the present invention ensures the safety of the baby when reproducing the parent's breathing. The specific ergonomics of the invention prevents any lateral mobilization of the baby, preferably an infant, during the inflation and / or deflation phases of the system. The specific inflation structure and electronic control include an alert mode when detecting respiratory and / or cardiac abnormalities of the baby, preferably the infant.

[0021] So, according to one scenario, the baby can benefit from reproducing the respiratory and heart rates of one of its parents during its period of sleep with an original vertical mobilization of his mattress without movements likely to endanger his breathing. According to this same scenario, a person can analyze the effectiveness of this reproduction by analyzing the induced changes in the baby's respiratory and / or heart rates.

[0022] The solution proposed by the invention is an inflatable system configured to be inserted into a support and comprising at least: a first inflatable zone configured to receive the head of a baby, a second inflatable zone configured to receive the body of the baby, a control and inflation module is configured to simultaneously: alternately inflate and deflate the first inflatable zone according to a first frequency, and alternately inflate and deflate the second inflatable zone according to a second predefined frequency distinct from said first frequency, the first frequency corresponding to a measured heart rate of a parent of the baby and the second frequency corresponding to a measured respiratory rate of said parent, which heart and respiratory rates are prerecorded and stored in a memory area accessible to said module.

[0023] The inflatable system according to the invention can be designed from known airbags for the protection of passengers in a motor vehicle. Generally, the inflatable system can be inflated from any type of fluid, more particularly a heat transfer fluid, such as water, air or a pressurized gas for example. The support of the inflatable system has an elongated shape, and can be oval or round, and more preferably, parallelepiped in shape.

[0024] The first and second inflatable zones, supporting the baby's head or body respectively, may have, for example, a parallelepiped, round or oval shape.

[0025] The control and inflation module of the inflatable system makes it possible in particular to control the inflation and / or deflation of said system, and comprises at least one electronic component, such as an analysis and control unit, which will determine the inflation and deflation frequency of said system. These first and second frequencies are predefined by the unit analysis, and more particularly in the memory area of ​​said unit, that is to say that these frequencies are pre-recorded and chosen by the user of the inflatable system.

[0026] The pre-recorded respiratory and heart rates of one of the parents are preferably resting respiratory and heart rates. Using both types of heart and respiratory rates of one of the parents for inflation and / or deflation of the inflatable system enhances the calming effect of said system on the baby.

[0027] By "baby" we mean a young subject, preferably a child under three years of age, such as, in particular, an infant. The term "baby" will be used in the remainder of the application and may refer, indiscriminately, to any child under three years of age, or an infant.

[0028] By "parent of the baby" we generally mean a third party who is preferably in regular contact with the baby, and who is used, for example, to helping him fall asleep. This is more preferably the father or mother of the baby.

[0029] Other advantageous features of the system that is the subject of the invention are listed below. Each of these features can be considered alone or in combination with the remarkable features defined above. Each of these features contributes, where appropriate, to the resolution of specific technical problems defined further in the description and in which the remarkable features defined above do not necessarily contribute. The latter may be the subject, where appropriate, of one or more divisional patent applications.

[0030] According to a preferred embodiment, the second inflatable zone comprises two lateral inflatable elements extending longitudinally on each side of the first inflatable zone, said lateral inflatable elements forming obstacles capable of limiting the movement of the baby during inflation and / or deflation of said first zone and / or said second zone.

[0031] Each side inflatable element extends over or into approximately half of the inflatable system support, with both elements positioned symmetrically with respect to the first zone. This makes it easier to control the inflation and / or deflation of each element, since the size of each inflatable element is smaller.

[0032] The specific positioning of the lateral inflatable elements improves the baby's position on the system, preventing any lateral mobilization of the baby, preferably the infant, during the inflation and / or deflation phases of the system.

[0033] Throughout the text, the first lateral inflatable chamber may be referred to, for the sake of simplification, as "first chamber" or "lateral chamber". Similarly, throughout the text, the second medial inflatable chamber may be referred to, for the sake of simplification, as "second chamber" or "medial chamber".

[0034] According to a preferred embodiment, each lateral inflatable element comprises a first lateral inflatable chamber and a second medial inflatable chamber fluidly connected to said first chamber, the volume of the first chamber being greater than the volume of the second chamber.

[0035] The second medial inflatable chambers of the lateral inflatable elements are shorter than the corresponding first lateral inflatable chambers, which explains the lower volume of the medial chambers compared to the volume of the lateral chambers. This design feature is notably due to the presence of the first zone configured to receive the baby's head at one of the ends of the support. In addition, the average diameter of the medial chambers is advantageously smaller than the average diameter of the lateral chambers, in particular during maximum inflation of said chambers, so as to facilitate maintaining the baby in an adequate position within the system during its operation. This maintenance in position is also facilitated by the differences in volumes between the medial and lateral chambers.

[0036] According to a preferred embodiment, at least one conduit provides fluid communication between the first chamber and the second chamber.

[0037] The conduit is advantageously positioned at an opposite end of the conduits allowing the entry and exit of fluids from the lateral inflatable element, so as to have optimal circulation of the fluid within said element, and so that the fluid can diffuse throughout all the chambers.

[0038] According to a preferred embodiment, when inflating a lateral inflatable element, the inflation fluid is introduced from an inflation orifice opening into the first chamber, so that said first chamber inflates before the second chamber.

[0039] The successive inflation of the first chamber and then the second chamber of each side inflation element means that the first chambers are always more inflated than the second chambers during operation of the system, thus allowing the baby to be kept within said system during its operation.

[0040] According to a preferred embodiment, the inflation port is connected to a pump controlled by the module.

[0041] The term "pump" means any device that can inflate and / or deflate the inflatable system. Such a pump may be replaced by a compressor.

[0042] According to a preferred embodiment, when deflating a lateral inflatable element, the inflation fluid is extracted from a deflation orifice opening into the second chamber, so that the first chamber deflates after said second chamber.

[0043] Deflation of the medial chambers prior to deflation of the lateral chambers of the side inflatable elements allows the baby to be held within the system during the inflation and / or deflation phases, thus limiting the risk of the baby rolling over.

[0044] According to a preferred embodiment, the deflation port is connected to a pump controlled by the module.

[0045] Using a pump improves the efficiency of deflating the elements.

[0046] According to a preferred embodiment, the deflation orifice is connected to a solenoid valve controlled by the module, which solenoid valve has an open position exposing said orifice to the open air during deflation.

[0047] Advantageously, the solenoid valve can be replaced by any inflation or deflation valve known to those skilled in the art.

[0048] According to a preferred embodiment, the first inflation zone comprises at least one inflatable element, during inflation of said inflatable element, the inflation fluid is introduced into said inflatable element from an inflation conduit opening into said inflatable element, during deflation of said inflatable element, the inflation fluid is extracted from said inflatable element from a deflation conduit opening into said inflatable element, which deflation conduit is separate from the inflation conduit.

[0049] Alternatively, the inflation duct and deflation duct may be one duct.

[0050] The inflatable element of said first zone may have, for example, a parallelepiped, round or oval shape, the inflatable element being able to extend over all or part of the first inflatable zone. Alternatively, said element may form, for example, a partially closed chamber, extending longitudinally so as to form a profile and partially surround the baby's head.

[0051] According to a preferred embodiment, the inflation conduit is connected to a pump controlled by the module.

[0052] According to a preferred embodiment, the deflation conduit is connected to a pump controlled by the module.

[0053] Alternatively, the inflation and deflation lines of the first inflatable zone can be connected by a single pump.

[0054] According to a preferred embodiment, the deflation conduit is connected to a solenoid valve controlled by the module, which solenoid valve has an open position exposing said conduit to the open air during deflation.

[0055] The solenoid valve allows the deflation duct to open, leading to the passive extraction of fluid from the inflatable element.

[0056] According to a preferred embodiment, it further comprises pressure sensors positioned in the middle position between the first inflatable chamber and the second medial inflatable chamber of each lateral inflatable element, so as to be able to measure the respiratory rate of the baby when said baby is installed on the support, the respiratory rate of the baby being analyzed by the module, said module being configured to exercise feedback on the inflation and / or deflation of the inflatable system in the event of a change in said rate.

[0057] The specific positioning of the pressure sensors on the system makes it possible to know the baby's breathing, in particular its respiratory rate. This makes it possible to determine whether the baby has breathing disorders such as apnea. By "pressure sensors", we mean that at least one, preferably two pressure sensors are mounted on each lateral inflatable element, in particular between the lateral and medial chambers of each element. These sensors measure the pressure variations caused by the baby. Due to their medial position, and more particularly thanks to their lateral positioning at the level of the baby's abdomen, they will be particularly well located to capture the baby's ventral breathing, and will be able to verify whether this breathing is normal or altered. Other sensors, such as stretch sensors, or measuring other physical, physiological or biometric parameters of the baby, may possibly be used.

[0058] The measurements of the baby's respiratory and heart rates and their analysis by the microprocessor make it possible to evaluate the effectiveness of the reproduction of breathing (by studying, for example, the respiratory frequency and amplitude of one of the parents) and / or the heart rate of one of the parents by studying the variations induced on the evolution of the baby's respiratory and heart rates.

[0059] Advantageously, the module comprises at least one pressure analyzer and / or one stretch analyzer translating the baby's respiratory cycle. These analyzers respectively study the pressure variations and / or the stretch variations induced by the baby's breathing on the chambers. The control and inflation module also comprises a mode for detecting the baby's heart rate, which may be a pressure sensor and / or a sound analyzer equipped, for example, with a microphone. All the data concerning the baby, measured and stored by the module, will eventually allow for feedback on the system's operation. Thus, if the baby's breathing rate is increased, the system could consider that the baby is waking up, and a reactivation of the system, so as to inflate and / or deflate the system according to the breathing and heart rates of one of the parents, could be considered in order to calm the baby.

[0060] Thanks to the system according to the invention, the baby's comfort will be improved thanks to a verification of the physical, biometric and physiological modifications thus induced, said modifications being represented in particular by the baby's respiratory and / or cardiac frequency measured by pressure and / or stretch sensors integrated into said elements.

[0061] According to a preferred embodiment, the control and inflation module is configured to alternately inflate and deflate the second inflatable zone such that the volume variations of the first and second inflatable chambers reproduce the measured variable amplitude of the parent's respiratory movements, which amplitude is pre-recorded and stored in the memory area.

[0062] By "variable amplitude" we mean that variations in parental breathing are reproduced by the middle chambers, which makes the system more efficient.

[0063] According to a preferred embodiment, the second medial inflatable chambers are configured so that their vertical inflation amplitude is between 1 cm and 5 cm.

[0064] The inflation amplitude of the medial chambers is, particularly advantageously, less than the inflation amplitude of the lateral chambers, due to the volume and the smaller diameter of said chambers and in order to allow the baby to be maintained within the system during the inflation and / or deflation phases of said system. Thus, the preferred inflation amplitude of the medial chambers is between 1 cm and 5 cm.

[0065] According to a preferred embodiment, the vertical inflation amplitude of the side chambers of the side inflatable elements is between 1 cm and 15 cm, so as to limit the movement of the baby.

[0066] The inflation amplitude of the side chambers corresponds to the height of said chambers, and to their variation according to their state of inflation, between a minimum position, close to 0 and corresponding substantially to the thickness of the fabric forming the inflatable element, to an amplitude between 1 cm and 15 cm. By "fabric", we mean a material capable of hermetically and tightly containing a fluid, to prevent the passage of the fluid into the external environment, whatever the fluid chosen. For example, the inflatable elements can be made of plastic or polymer materials.

[0067] The 15cm amplitude of the side chambers corresponds to the maximum amplitude of inflation of the side chambers. This amplitude is important so that the baby is effectively held on the inflatable system, regardless of the state of inflation of said chambers. This improves the lateral stability of the baby, in order to limit any risk of rolling over. The maximum inflation of the side chambers allows the system to be used to move the baby, in particular when traveling in a motor vehicle. In this case, the baby's pram is advantageously positioned transversely to the seat. Also, the inflation of the side chambers allows the baby to be held within the system, even during sudden braking.

[0068] According to a preferred embodiment, a respiratory rate threshold value is recorded in the memory area, the pumps and / or solenoid valves of said system operate according to a first pressure and / or a first flow rate, so as to inflate said system according to the heart and respiratory rates of one of the parents, and the pumps and / or solenoid valves of said system are activated simultaneously, so as to cause inflation of said system according to a second pressure and / or a second flow rate higher than said first pressure and / or first flow rate, in the event that the module detects that the baby's respiratory rate exceeds said threshold value recorded in the memory area.

[0069] The first pressure and / or flow rate with which the module activates the pumps and / or solenoid valves are “normal” pressure and / or flow rate conditions, insofar as they will allow the inflation and / or deflation of the inflatable elements constituting the system, when the heart and / or respiratory rates of the parents are used. The second pressure and / or flow rate are considered, particularly advantageously, as pressures and / or flow rates, preferably maximum, produced by the module, so as to cause inflation of said system as quickly as possible (particularly advantageously, inflation must be carried out for a duration of less than 1 second). Thus, the inflation elements pass from a deflated state to an inflated state, according to a preferably maximum inflation amplitude.This primarily stimulates the baby by giving it a "shock," potentially causing a positive response in the baby's respiratory rate. One of the goals of such stimulation would be to potentially bring the baby's respiratory rate back below threshold values.

[0070] Advantageously, the unit for analyzing and controlling the inflation and / or deflation phases of the inflatable system consists of at least one microprocessor (also called a “central computing unit” whose acronym is “UCC”; or in English “central processing unit”, whose acronym is “CPU”), said microprocessor preferably being integrated into an electronic card. This microprocessor can be replaced by a device with an equivalent function known to those skilled in the art.

[0071] More specifically, the microprocessor is connected to the inflatable units and valves, which are controlled by the microprocessor, so that it controls the inflation and / or deflation cycles of the inflatable elements, their inflation volumes according to the respiratory and heart rates, and according to the respiratory amplitudes of one of the parents.

[0072] Advantageously, the memory area of ​​the analysis and control unit allows the storage of pre-recorded data, it is also mounted on the electronic card. These data can be respiratory data (frequency, amplitude) and cardiac data of one of the parents, as well as data (respiratory and heart rates, breathing amplitude) of the baby recorded using the inflatable system. This data can be compared with data recorded on the memory area, and possibly allow for feedback on the system's operation. The memory area can be any device capable of recording data, such as a memory card or hard drives for example.

[0073] Advantageously, the control and inflation module may also comprise an input / output interface, which may also be mounted on the electronic card, this interface being able to comprise a wireless exchange system, using for example, Wi-Fi or Bluetooth™, or a wired exchange system. These different systems are known to those skilled in the art.

[0074] Advantageously, the control and inflation module may optionally include a clock or an equivalent device so as to measure time and enable the module to operate.

[0075] Advantageously, the control and inflation module further comprises a device for powering the inflatable system, this device enabling the electrical power supply to the system and enabling its operation. This device may comprise a power cable for powering said system via an electrical circuit. In a particularly preferred manner, the power device may comprise a main battery configured to take over in the event of a power failure, when the inflatable system is being moved, for example. Alternatively, the battery may be the preferred operating mode, the power cable then only enabling the battery to be recharged.In a particularly preferred manner, a backup battery may also be present in the control and inflation module, said battery being configured to take over and power the module in the event of the main battery being empty, if the inflatable system is autonomous for a long period, for example.

[0076] Advantageously, the control and inflation module of the inflatable system may comprise a thermal management device, which measures and controls the temperature of the fluid circulating in the inflatable system. Thus, this device may comprise thermistors, heating means such as a radiator, a resistor or other means performing a function identical or similar to said heating means and known to those skilled in the art. This device may also include a component for measuring the temperature of the fluid, controlling it so that it is adapted according to the baby's needs. This device could also include cooling means, in the event that the fluid is too hot.

[0077] Advantageously, the module may also comprise a fluid reservoir, preferably a heat transfer fluid, such as a liquid or a gas. This reservoir may not be present, in particular when the fluid is ambient air.

[0078] Thus, the electronic card of the control and inflation module: a. Ensures the storage of the respiratory and heart rates of the parents and the baby, as well as the variations in the respiratory amplitudes of the parent(s). b. Includes a program for analyzing the changes induced by the parental parameters on the respiratory and / or heart rates of the baby. c. Includes a program for controlling the inflation and / or deflation of the various inflatable elements. d. Includes a program for activating the alert mode ensuring emergency inflation upon detection of predefined physical, physiological and / or biometric parameters of the baby. e. Also includes a module for receiving and / or transmitting the data collected, in order to transmit said data wirelessly to a remote display mode (on a dedicated application, a terminal, a smartphone, or a computer for example).

[0079] Thanks to these characteristics, it is possible to program a reproduction of the respiratory and / or cardiac cycles of any person or animal, preferably one of the parents, by means of the invention. Advantageously, the programming can concern one or more of the parents, or even another person.

[0080] According to an alternative embodiment of the invention, the inflatable system may comprise, in the second zone, a single inflatable element having an extended shape with inflatable zones physically separated or linked together so as to be able, or not, to allow the movement of fluid from one zone to another. The inflatable element also comprises solid zones positioned between the inflatable zones. Thus, two lateral inflatable zones are advantageously provided on each side of the baby's body so as to surround, at least partially, the baby's body. At least one medial inflation zone, configured to be positioned under the baby's body, is also provided, and can be inflated and / or deflated to a lesser extent than the lateral inflatable zones.

[0081] According to another embodiment of the invention, each lateral and medial chamber of each lateral inflatable element can be mounted individually on the control and inflation module, and therefore be controlled individually. By individual mounting, it is meant that the lateral and medial chambers of each lateral inflatable element are not in communication with each other. Optionally, the chambers can be attached to the module by means of two conduits. Alternatively, each chamber can have a single conduit with a two-way valve, allowing both the inflation and / or deflation of the corresponding chamber, and a pump allowing this inflation and / or deflation. In fact, successive inflation of the lateral chambers and then the medial chambers can be carried out by the module, so as to be able to ensure the support of the baby during the inflation and / or deflation phases of the system.The volume and diameter of the lateral chambers are also greater than the volumes and diameters of the medial chambers, for the same reasons of baby support as mentioned previously.

[0082] Advantageously, the inflatable system may also comprise one or more microphones configured to broadcast a pre-recorded sound, the microphone(s) (also called pickups) being advantageously installed at the first inflatable zone. The actuation of the microphones may be complementary or alternative to the inflation system, for example following measured data from the baby's respiratory and heart rates.

[0083] This sound may for example be music or the pre-recorded voice of one of the parents interpreting a read text or a song. In a particularly preferred manner, the pre-recorded voice is that of the parent whose heart rate and / or respiratory rate is used to operate the inflatable system. It is advantageously recorded in the memory area to which the control and inflation module of the inflatable system has access. The use of a parent's voice makes it possible to improve the soothing of the baby, in particular when the sensors, and more specifically, the pressure sensors located on the inflatable system record an acceleration of the heart rate and / or the respiratory rate of the baby. The broadcasting of the parent's voice by the microphones, coupled with the inflation of the first and second zones of the inflatable system according to the heart and respiratory rates of said parent, allows a synergistic calming action on the baby.

[0084] The invention also relates to a mattress configured to be positioned in a baby bed and / or on a seat, said mattress comprises an inflatable system according to the invention, said system comprising side chambers whose vertical inflation amplitude is between 1cm and 15cm.

[0085] The mattress according to the invention has the particularity of being able to be positioned in a baby's bed, a cradle or even a seat, such as a car seat. The side chambers will therefore play an important role in keeping the baby on its mattress, while it is moving. Thus, the baby is held in such a way as to ensure its lateral stability.

[0086] The invention also relates to a method for helping a baby to sleep or fall asleep, comprising the following steps: measuring the heart rate of a parent of the baby; measuring the respiratory rate of said parent; and when the baby is installed on a support: installing a first inflatable zone under the baby's head, installing a second inflatable zone under the baby's body, alternately inflating and deflating the first inflatable zone according to a first frequency corresponding to the measured heart rate, and simultaneously alternately inflating and deflating the second inflatable zone according to a second frequency corresponding to the measured respiratory rate.

[0087] This method, preferably using the aforementioned systems and / or mattresses, makes it possible to improve the effects of such a system, in particular the calming effect on babies.

[0088] Thanks to the inflatable system according to the invention, the safety of the baby will be ensured on the one hand, by the specific ergonomics of the first and second inflatable zones, on the other hand by the monitoring of the physical, physiological and / or biometric modifications of the baby, and finally by the capacity of the inflatable system to be able to possibly generate an urgent stimulation mode in vertical inflation (also called alert mode).

[0089] Advantageously, the programming of the system can be applied during periods of rest, sleep or any other periods chosen for the benefit of the baby. Thanks to these characteristics, said reproduction is carried out under safe conditions, said conditions including the absence of lateral tilting mobilization of the baby's body and an alert mode initiated according to one or more predefined critical parameter(s) (respiratory arrest, bradypnea, tachypnea, cardiac arrest, bradycardia, tachycardia). The measurements of the baby's respiratory and heart rates make it possible to trigger this system alert mode when predefined thresholds are exceeded, concerning the baby's heart rate and / or respiratory rate, predefined thresholds consisting of bradycardia, tachycardia, bradypnea, tachypnea thresholds.The alert mode consists of a maximum and sudden inflation of all the inflatable elements, therefore a sudden vertical mobilization, in order to stimulate the baby.

[0090] Advantageously, the microprocessor includes a permanent inflation mode ensuring the physical stability (head, thorax and abdomen) of the baby during periods of transport.

[0091] Advantageously, the hospitalized baby, therefore far from his parents, can benefit from reproducing the respiratory and heart rate of one of his parents during his sleep period with an original vertical mobilization of his mattress without movements likely to endanger his breathing. According to this same scenario, a person can analyze the effectiveness of this reproduction by analyzing the induced changes in the baby's respiratory and / or heart rate.

[0092] Advantageously, the invention also relates to a therapeutic method for treating babies using an inflatable system according to the invention, said method comprising a first step of measuring physical, biometric and / or physiological parameters of the baby by measuring sensors, a second step of comparing these parameters with parameters pre-recorded in the memory area of ​​the module, a third step of determining a difference between the recorded parameters and the measured parameters, a fourth step of determining the pathological phenomenon of the baby (bradycardia, tachycardia, bradypnea, tachypnea), and a fifth step of activating the alert mode of said system, resulting in rapid and maximum inflation of the inflatable elements in order to apply stimuli to the baby, or sudden vertical mobilization of the baby.

[0093] Possibly, a sixth step of measuring the physical, biometric and / or physiological parameters of the baby, in order to determine if the pathological phenomenon has been resolved.

[0094] Possibly, a seventh stage of alert of sound, vibration, or by receiving a notification on a computer or smartphone for example, so that the parents and / or available medical personnel can take care of the baby if the pathological phenomenon has not been resolved.

Description of the embodiments.

[0096] As used herein, and unless otherwise indicated, the use of the ordinal adjectives "first", "second", etc., to describe an object merely indicates that different occurrences of similar objects are referred to and does not imply that the objects so described must be in any given sequence, whether in time, space, ordering, etc. "X and / or Y" means: X alone or Y alone or X+Y. Generally speaking, it will be appreciated that in the various accompanying drawings, the objects are arbitrarily drawn to facilitate their reading. The adverbs "upstream" and "downstream" are used in relation to the flow of fluid in the valve and / or the fluid circuit in which the valve is installed.

[0097] The main longitudinal axis of the support is the longest axis of the support, depending on the direction in which the baby is positioned. The support may be, for example, parallelepiped, oval or circular in shape.

[0098] Figure 1 is a diagram of an inflatable system according to the invention, adapted to be inserted into a support.

[0099] More specifically, in this figure, an inflatable system 1 according to the invention is shown as being inserted into a support M for a baby, and being able to be used on a motor vehicle seat, a bed, or a cradle for example. Preferably, the support M is a mattress M having a substantially parallelepiped shape, or, alternatively, a substantially oval or round shape. Thus, it is possible to adapt the shape of the mattress M, and more generally, the shape of the support M, to the shape of the object in which it is to be installed. An oval or round shape can be particularly interesting when this mattress M is to be integrated into a cradle for example. “substantially” means that the M mattress has a shape that is close to the shape described, with possible variations due in particular to manufacturing hazards.

[0100] Such a mattress M may also comprise the usual padding materials known to those skilled in the art. Alternatively, the support M may also be in the form of a cushion, such as cushions intended for breastfeeding, and may therefore be adapted accordingly. Variations in the design of the inflatable system according to the invention are also possible. The inflatable system 1 may be permanently integrated into the mattress M, but, alternatively, the inflatable system 1 may be manufactured separately from its support.

[0101] In a particularly advantageous manner, the mattress M has a main longitudinal axis Ap, this axis Ap determining the particularly preferred positioning of the different components of the mattress M according to the positioning of the baby's body on said mattress M. Thus, this mattress M preferably has a first end Mi at which the baby's head will be positioned, and a second end M2 towards which the baby's body will be oriented, the two ends (Mi, M2) being opposite each other.

[0102] Thus, the inflatable system 1 extends preferentially along the main longitudinal axis Ap of the mattress M. The inflatable system 1 can be inflated and / or deflated according to a predefined frequency, using a fluid. This fluid is preferentially a heat transfer fluid which can also retain and transmit heat. warmth to the baby. This fluid can be, for example, air, a pressurized gas, or water.

[0103] The inflatable system 1 according to the invention therefore comprises a first inflatable zone 3 configured to receive the baby's head, therefore oriented towards the first end Mi of the mattress M. This first zone 3 comprises at least one inflatable element 3A configured to be able to inflate and / or deflate alternately according to a predefined frequency. Alternatively, the first zone 3 may comprise several inflatable elements which may, for example, surround the baby's head and whose inflation, carried out on a smaller scale, will be faster and will more effectively hold the baby's head in position. For example, these elements may form a semicircle with an open portion oriented towards the baby's body, this variant not being shown in these figures.Other variant embodiments, not mentioned, are also possible, in order to limit significant movement of the baby's head during the inflation and / or deflation phases of said inflatable element(s).

[0104] The inflatable element 3A can be inflated and / or deflated using at least one conduit (3B, 3C). Preferably, the inflatable element 3A is supplied by two conduits (3B, 3C), a first inflation conduit 3B opening into the inflatable element 3A and through which the inflation fluid is introduced into the inflatable element 3A, and a second deflation conduit 3C opening into the inflatable element 3A and from which the inflation fluid is extracted from said element 3A, each conduit (3B, 3C) therefore allowing either the entry of the fluid into the element 3A, or the exit of fluid.

[0105] The inflatable system 1 further comprises a second inflatable zone 5 particularly suitable for receiving the baby's body. This second zone 5 extends between the first end Mi and the second end M2 of the mattress M.

[0106] The second zone 5 of the inflatable system 1 comprises at least one inflatable element, preferably at least two lateral inflatable elements (5A, 5A') positioned symmetrically to each other, on each side of the mattress M and on either side of the conduits (3B, 3C) of the first zone 3. In all cases, the lateral inflatable elements (5A, 5A') extend longitudinally between the first and second ends (Mi, M2) of the mattress M, and more particularly on each side of the first zone 3. In this way, even when the inflatable element 3A of the first zone 3 is operating and / or when the inflatable elements (5A, 5A) of said second zone 5 are operating, the baby will be limited in its movements by the inflatable elements (5A, 5A) of the second zone 5, said lateral inflatable elements (5A, 5A) forming obstacles. The risk of the baby rolling over, or its lateral mobilization, is thus limited.

[0107] In a particularly preferred embodiment of the invention, each lateral inflatable element (5A, 5A) comprises a first lateral inflatable chamber (5A.1, 5A.1) which extends longitudinally between the first and second ends (Mi, M2) of the mattress M, and on an edge M3 of said mattress M. Preferably, this lateral chamber (5A.1, 5A'.1) has a profile shape with a continuous diameter along the entire length of said chamber (5A.1, 5A.1). Alternatively, certain sections of the first lateral inflatable chamber (5A.1, 5A.1) may be narrowed.

[0108] Each lateral inflatable element (5A, 5A) further comprises a second medial inflatable chamber (5A.2, 5A'.2) which extends longitudinally between the first and second ends (Mi, M2) of the mattress M, and centrally to the lateral chambers (5A.1, 5A'.1) so that the baby's body is positioned on said second chambers (5A.2, 5A'.2). In a particularly preferred manner, the volume of the first lateral inflatable chambers (5A.1, 5A.1) is greater than the volumes of the second medial inflatable chambers (5A.2, 5A'.2), thus ensuring the stability of the baby, in particular during operation of the inflatable system 1. This volume variation is controlled by the module 7. In particular, the volume variation of the lateral and medial chambers (5A.1, 5A.1, 5A.2, 5A.2) reproduces the measured variable amplitude of the parent's respiratory movements, the amplitude being pre-recorded and stored in a memory area of ​​the module 7 (said area being shown in Figure 2). Advantageously, the vertical amplitude of inflation of the medial chambers (5A.2, 5A.2) is between 1cm and 5cm. In addition, the vertical amplitude of inflation of the lateral chambers (5A.1, 5A.1) is. preferably between 1cm and 15cm, and intended to limit the baby's movement on the system.

[0109] Preferably, the medial chamber (5A.2, 5A'.2) also has a profile shape with a continuous diameter along the entire length of said chamber (5A.2, 5A.2). Alternatively, certain sections of said chamber (5A.2, 5A.2) may be narrowed.

[0110] In a particularly preferred manner, the lateral (5A.1, 5A.1) and medial (5A.2, 5A'.2) inflatable chambers of each lateral inflatable element (5A, 5A') will be fluidically connected by a conduit (5A.3, 5A.3) preferably positioned near the first end Mi of the mattress M and which will allow the passage of the fluid, therefore the fluidic communication, from the lateral chambers (5A.1, 5A'.1) to the medial chambers (5A.2, 5A.2).

[0111] Preferably, each inflatable element (3A, 5A, 5A') comprises at least one conduit allowing the entry or evacuation of the fluid from said element. More particularly, each lateral inflatable element (5A, 5A) comprises two conduits (5A.4, 5A.4; 5A.5, 5A.5). A first conduit (5A.4, 5A.4) is used for introducing the fluid into the corresponding lateral inflatable element (5A, 5A) from an inflation orifice opening into the lateral chamber (5A.1, 5A'.1), said conduit (5A.4, 5A'.4) being positioned at said orifice. A second conduit (5A.5, 5A.5) is used for extracting the fluid from said inflatable elements (5A, 5A'), from a deflation orifice opening into the medial chamber (5A.2, 5A.2). Said conduit (5A.5, 5A'.5) is therefore positioned at the level of the medial chamber (5A.2, 5A.2) of the corresponding lateral inflatable element (5A, 5A'). Thus, in a particularly preferred manner, each lateral chamber (5A.1, 5A.1) and medial chamber (5A.2, 5A.2) lateral inflatable elements (5A, 5A) comprise at least one conduit (5A.4, 5A'.4; 5A.5, 5A'.5) each.

[0112] The inflatable system 1 further comprises a control and inflation module 7 positioned at the second end M2 of the mattress M. This module 7 performs several functions within the inflatable system 1: it makes it possible to measure and control the state of inflation and / or deflation of the different inflatable elements (3A, 5A, 5A'), and possibly to measure and monitor physical, biometric or physiological parameters of the baby installed on said mattress M. Thus, the module 7 can simultaneously inflate and deflate, alternately, the first inflatable zone 3 according to a first frequency, and simultaneously inflate and deflate the second inflatable zone 5 according to a second frequency distinct from said first frequency. This control and inflation module 7 of the inflatable system 1 will be described in more detail in the next figure.

[0113] In a first variant embodiment of the invention not shown in these figures, the second zone comprises only a single inflatable element, which extends substantially over the entire surface of the support in or on which it is to be inserted. Thus, certain longitudinal zones of said element can, for example, be inflated or deflated, the rest of the element being able to form a structure closed by plastic welds, for example.

[0114] Figure 2 shows an enlargement of a possible variant embodiment of the control and inflation module according to the invention.

[0115] This module 7 is attached to the various inflatable elements (3A, 5A, 5' A) by the conduits (3B, 3C, 5A.4, 5A'.4, 5A.5, 5A.5), so as to be able to exert an inflation and / or deflation action on the various elements (3A, 5A, 5' A).

[0116] This module 7 firstly includes one or more 7A pumps. By "pump" means a device capable of alternately inflating and / or deflating an inflatable element using a fluid. Thus, a pump 7A, within the scope of the invention, can also be a compressor. In this figure, three pumps 7A are shown, one for each inflatable element (3A, 5A, 5A). Each pump 7A is connected either to the inflation port of the corresponding inflatable element (5A, 5A'), or to the corresponding inflation conduit 3B, the pumps 7A being controlled by the module 7. Alternatively, a single pump 7A can control the supply and output of fluid from the different elements (3A, 5A, 5A'). Alternatively, a first pump 7A can control the fluid flow (in and out) of the inflatable element 3A, and a second pump 7A serves to control the fluid flow (in and out) of the side inflatable elements (5A, 5A) of the second zone.

[0117] These pumps 7A are also connected to a fluid circuit 7B by the inflation orifice, which allows the introduction of the fluid into the different inflatable elements (3A, 5A, 5A'). In the variant embodiment of the invention shown in this figure, the fluid circuit 7B comprises fluid inlet pipes 7B.1 which connect the external environment to the pump 7A of said element (3A, 5A, 5A), said pipes 7B.1 allowing the supply of the corresponding element (3A, 5A, 5A') with fluid. Thus, in Figure 2, the number of inlet pipes 7B.1 is three. The pump 7A is advantageously positioned, in this variant, upstream of the lateral chamber (5A.1, 5A'.1) of the corresponding inflatable element (5A, 5A), at the level of the inflation conduit 3B of the inflatable element 3A.

[0118] The fluid circuit 7B also comprises fluid outlet pipes 7B.2, which will allow the fluid to be evacuated from the corresponding inflatable element (3A, 5A, 5A'). In the case of the inflatable element 3A of the first zone, the outlet pipe 7B.2 extends from the deflation pipe 3C to the control and inflation module 7. In the case of the lateral inflatable elements (5A, 5A), an outlet pipe 7B.2 extends from the second pipe (5A.5, 5A.5) of the medial chamber (5A.2, 5A.2) of each element (5A, 5A), the three pipes 7B.2 preferably joining together so that the system 1 has only one fluid evacuation orifice 7B.3, thus simplifying the system 1.

[0119] When the fluid is ambient air, as shown in Figures 1 and 2, the inlet pipes 7B.1 each have a fluid inlet orifice 7B.4 providing communication between said pipes 7B.1 of the inflatable system 1 and the external environment. The fluid outlet orifice 7B.3 allows communication between all the outlet pipes 7B.2 of the fluid circuit 7B, and the external environment. On the other hand, when the fluid is a pressurized gas, or a fluid such as water requiring, for its introduction into the inflatable system 1, to be maintained in a reservoir, the fluid circuit 7B can be designed differently, with, for example, only one inlet pipe outside the inflatable system 1 so as to limit the number of pipes and simplify the system 1. Alternatively, the reservoir can simply be Tl mounted at the end of the mattress where the control and inflation module 7 is located, at the three inlet lines, and only one outlet line may be required, constructed so as to close the circuit 7B by returning the fluid to the reservoir.

[0120] The control and inflation module 7 further comprises valves 7C positioned at the junction between the first and second conduits (3B, 5A.4, 5A'.4, 3C, 5A.5, 5A.5) and the control and inflation module 7. These valves 7C may preferably be mechanical valves 7C or solenoid valves 7C, the particularly preferred embodiment using solenoid valves 7C. These valves 7C may be unidirectional, that is to say allow the passage of the fluid in only one direction, leading either to the inflation or to the deflation of the inflatable elements (3A, 5A, 5A'). In the embodiment shown in Figure 2, the valves 7C positioned at the first conduits (5A.4, 5A.4) of the side chambers (5A.1, 5A'.1) and the first conduit 3B of the inflatable element 3A are preferably unidirectional valves 7C, allowing the passage of fluid from the pump 7A to the corresponding inflatable element (3A, 5A, 5A').Likewise, the valves 7C positioned at the level of the second conduits (5A.5, 5A'.5) of the medial chambers (5A.2, 5A.2) and of the second conduit 3C of the inflatable element 3A are preferably unidirectional valves 7C, allowing the passage of fluid from the inflatable element (3A, 5A, 5A) to the outside.

[0121] When the inflatable element 3A is supplied by only one conduit, a two-way valve can be provided, which will then allow the passage of the fluid in both directions, and will therefore allow, in an undifferentiated manner, the inflatable elements (3A, 5A, 5A') to be inflated or deflated alternately. This embodiment is not shown in this figure.

[0122] In order to control the inflatable units 7A and / or the valves 7C, an analysis and control unit 7D may be included in the module 7. In a particularly preferred manner, said analysis unit 7D comprises an electronic card on which a microprocessor 7D is mounted.1.

[0123] The 7D.1 microprocessor is used to execute computer programs contained in a 7D.2 memory area allowing data storage. Examples of memory areas 7D.2 that can be used in the context of the invention are a memory card, an external hard drive, etc.

[0124] This memory area 7D.2 may comprise different computer programs, such as a program for analyzing the physiological, biometric and / or physical parameters of the baby, before, during or after operation of the inflatable system 1, a program for controlling the inflatable elements (3A, 5A, 5A') and / or a safety program, allowing emergency inflation of the inflatable elements (3A, 5A, 5A), in response for example to deleterious physical, biometric or physiological parameters of the baby. The memory area 7D.2 may also record and store different frequencies, such as the first and second frequencies used to inflate and deflate the first and second inflatable zones. Preferably, said frequencies will be used to alternately inflate and / or deflate the inflatable elements (3A, 5A, 5A'), the memory area 7D.2 being accessible to said module 7.

[0125] These frequencies are preferably the heart and / or respiratory rates of a third party, preferably a relative of the baby, such as the father or mother, or a third party with whom the baby will be used to staying. The heart and respiratory rates of the mother can be particularly effective in an infant. These frequencies are preferably recorded using measuring devices known to those skilled in the art, preferably in a third party at rest. It would also be appropriate to record the variations in respiratory amplitudes of the third party or parent.

[0126] By "breathing amplitude" we mean the amount of movement of the rib cage when the third party breathes, i.e. the height to which the rib cage rises in relation to its resting position. This breathing amplitude, also applied to the inflation and / or deflation of the inflatable elements (3A, 5A, 5A'), will better imitate the presence of the selected third party, and improve the baby's impression of being in the arms of said third party.

[0127] The 7D analysis and control unit further comprises a 7D.3 input / output interface which allows the information received by the inflatable system 1 in particular, but also to transfer the information received by the various sensors analyzing the physical, biometric and / or physiological parameters of the baby. The analysis and control unit 7D may also include a clock 7D.4 which helps to determine said frequencies in real time.

[0128] The inflatable system 1 further comprises one or more power supply devices 9 for said system 1, this device 9 making it possible to supply the inflatable system 1 with electrical energy. The device 9 may comprise one or more power supply cables 9A for connection to an electrical circuit, in particular to enable the recharging of one or more batteries (9B, 9C). This power supply cable 9A may directly power the inflatable system 1 in order to enable its operation, or, alternatively, recharge the batteries (9B, 9C), said batteries (9B, 9C) then enabling the operation of the system 1. In a particularly preferred manner, the power supply device 9 comprises a main battery 9B which currently powers the system 1, when there is a stoppage of the electrical power supply or a movement of the inflatable system 1, for example.

[0129] Particularly preferably, a backup battery 9C may also be part of the power supply device 9, which is able to take over and power the inflatable system 1 when the main battery 9B is empty.

[0130] The inflatable system 1 may also comprise a thermal management device 11 which makes it possible to measure and control the temperature of the fluid circulating in the inflatable system 1. Thus, this device 11 may comprise thermistors, heating means such as a radiator, a resistor or other means performing an identical or similar function which are known to those skilled in the art. This device 11 may also comprise a component allowing the temperature to be measured and controlled so that it is adapted to the needs of the baby. This device 11 could also comprise cooling means, in the event that the fluid is too hot.

[0131] Finally, the inflatable system 1 may comprise at least one analyzer 13 of the physical, biometric and / or physiological parameters of the baby installed on said system 1. This analyzer 13 will study the data brought by the different sensors 15 installed on said system 1, and convert this data into physical, biometric and / or physiological parameters of the baby to determine its state of health. For example, the system 1 may comprise pressure sensors 15 preferentially positioned between the medial (5A.2, 5A'.2) and lateral (5A.1, 5A.1) chambers of each lateral inflatable element (5A, 5A). Due to their position median to said inflatable elements (5A, 5A'), these sensors 15 will measure a pressure difference generated by the breathing (essentially ventral) of the baby, therefore measure the baby's respiratory rate. Advantageously, the module 7 will then analyze the data obtained by the sensors 15.The module 7 is advantageously configured to be able to exercise feedback on the inflation and / or deflation of the inflatable system, in the event of a change in the baby's respiratory rate. In a complementary and / or alternative manner, stretch sensors can also be installed on the system 1, and can perform the same function by measuring the stretching of the chambers (5A.1, 5A'.1, 5A.2, 5A'.2). Other sensors, not mentioned, could also be used to determine physical, biometric and / or physiological parameters of said baby (skin humidity, etc.).

[0132] Figure 3 is a view showing the circulation of the fluid in the lateral inflatable elements of the second zone, during an inflation phase.

[0133] In this figure, only a part of the inflatable system 1 for a mattress M is shown, more particularly the lateral (5A.1, 5A.1) and medial (5A.2, 5A.2) chambers of the two lateral inflatable elements (5A, 5A) of the second zone 5. Each chamber (5A.1, 5A.1, 5A.2, 5A.2) is attached to the control and inflation module 7 which controls the inflation and / or deflation of said chambers (5A.1, 5A'.1, 5A.2, 5A.2).

[0134] Particularly advantageously, the inflation of the lateral inflatable elements (5A, 5A) of the second zone 5 is carried out as follows. a. First of all, there is opening of the valve 7C positioned at the level of the first conduit (5A.4, 5A.4) of the lateral chamber (5A.1, 5A'.1), and closing of the valve 7C positioned at the level of the second conduit (5A.5, 5A'.5) of the medial chamber (5A.2, 5A'.2). The opening and closing of the valves 7C is controlled by the module 7, and more particularly by the microprocessor. b. Then, there is actuation of the pump (not shown in this figure) positioned upstream of the first conduit (5A.4, 5A.4). This actuation is carried out by the microprocessor, and leads to the introduction of inflation fluid from an inflation orifice into the first lateral chamber (5A.1, 5A.1) of each lateral inflatable element (5A, 5A). c. The fluid flows from the lateral chamber (5A.1, 5A.1) to the medial chamber (5A.2, 5A.2), thanks to the presence of the conduit (5A.3, 5A.3) positioned at the opposite end of said chambers (5A.1, 5A'.1, 5A.2, 5A'.2) of the first and second conduits (5A.4, 5A.4, 5A.5, 5A'.5). Thus, the lateral chambers (5A.1, 5A.1) will be partially inflated when the inflation of the medial chambers (5A.2, 5A.2) of the lateral inflatable elements (5A, 5A) begins.The inflation of the lateral chambers (5A.1, 5A.1) is therefore carried out before the inflation of the medial chambers (5A.2, 5A.2). Closing the valve 7C positioned at the end of the second conduit (5A.5, 5A.5) of the medial chambers (5A.2, 5A.2) prevents said chambers (5A.1, 5A.1, 5A.2, 5A'.2) from deflating prematurely.

[0135] Figure 4 is a diagram showing the circulation of fluid in the lateral inflatable elements, during a deflation phase of the inflatable system.

[0136] In this figure, only a part of the inflatable system 1 for the mattress M is shown, and more particularly, the lateral (5A.1, 5A.1) and medial (5A.2, 5A'.2) chambers of the two lateral inflatable elements (5A, 5A') of the second zone 5. Each chamber (5A.1, 5A.1, 5A.2, 5A.2) is attached to the control and inflation module 7 of the inflatable system 1, said module 7 controlling the inflation and / or deflation of said chambers (5A.1, 5A'.1, 5A.2, 5A'.2).

[0137] Particularly advantageously, the deflation of the lateral inflatable elements (5A, 5A') is carried out as follows. a. First, there is closing of the valve 7C positioned at the first conduit (5A.4, 5A.4) of the lateral chamber (5A.1, 5A'.1), and opening of the valve 7C positioned at the outlet of the second conduit (5A.5, 5A.5) of the medial chamber (5A.2, 5A'.2). The valve 7C, positioned at the outlet of the second conduit (5A.5, 5A.5), is preferably a solenoid valve 7C connected to the deflation orifice and controlled by the module 7. This valve has an open position exposing said orifice to the open air during deflation. The opening and closing of the valves 7C are controlled by the control and inflation module 7, and more particularly by the microprocessor of said module 7 (the microprocessor not being shown in these figures). b.Then, the pump can be actuated (said pump not being shown in this figure), when the pump is also located downstream of the lateral inflatable element (5A, 5A). In this case, the deflation port is connected to the pump. Deflation is then carried out actively by said pump controlled by the module 7. Alternatively, the deflation of the lateral inflatable elements (5A, 5A') is carried out passively, by simply opening the valves 7C positioned at the outlet of the second conduits (5A.5, 5A'.5). The fluid is extracted from the deflation port located on the second chamber (5A.2, 5A.2) then evacuated through the outlet conduits mentioned in figure 2 and not shown in this figure. c. The fluid is therefore evacuated from the medial chamber (5A.2, 5A.2) by the valve 7C of the second conduit (5A.5, 5A.5). The fluid, which always flows from the lateral chamber (5A.1, 5A'.1) to the medial chamber (5A.2, 5A.2) thanks to the presence of the conduit (5A.3, 5A.3), will be sucked in by the evacuation of fluid from the medial chamber (5A.2, 5A'.2). Thus, the medial chamber (5A.2, 5A'.2) will be partially deflated when the deflation of the lateral chamber begins. (5A.1, 5A'.1). Deflation of the lateral chambers (5A.1, 5A.1) is therefore carried out after deflation of the medial chambers (5A.2, 5A'.2), first by emptying the medial chambers (5A.2, 5A'.2) then by emptying the lateral chambers (5A.1, 5A'.1). Closing the valve 7C positioned at the inlet of the first conduit (5A.4, 5A.4) of the lateral chambers (5A.1, 5A.1) prevents said chambers (5A.1, 5A.1, 5A.2, 5A'.2) from inflating again.

[0138] The inflation and deflation of the lateral inflatable elements (5A, 5A') shown in Figures 3 and 4 is advantageously carried out at the second frequency, said frequency advantageously being a measured respiratory frequency of one of the parents. Preferably, the respiratory frequency is coupled with the use of the respiratory amplitude of said parent, in order to improve the efficiency of said system.

[0139] In the inflation and deflation of the lateral inflatable elements (5A, 5A') described in figures 3 and 4, the direction of inflation and deflation of the different chambers is important to allow the baby to be held within the inflatable system, and to avoid its displacement, or poor positioning which could be harmful to the baby's health.

[0140] Thus, two embodiment variants are possible for the inflation and / or deflation of the inflatable system. The pump is either only attached to the first conduit, and only allows the entry of fluid into the lateral inflatable element (embodiment variant shown in Figure 2), or, alternatively, the pump is attached to both conduits and allows both the entry and exit of fluid from the corresponding lateral inflatable element. In the first case, the pump will be positioned only upstream of the corresponding lateral inflatable element. In the second case, the pump must be positioned both upstream and downstream of the corresponding lateral inflatable element, so as to carry out the two activities of inflation and deflation of said element. This therefore requires a different design of the fluid circuit than that mentioned in Figure 2, with an inlet and outlet of the fluid circuit from the pump.

[0141] Figures 5 and 6 are sectional diagrams of the inflatable system according to the invention, on which the baby is positioned.

[0142] In these figures, the mattress M is shown with only a part of the inflatable system according to the invention, more precisely with the lateral (5A.1, 5A'.1) and medial (5A.2, 5A.2) inflatable chambers of the lateral inflatable elements of said system. These views make it possible in particular to see the technical effect provided by the difference in volume and diameter of the lateral chambers (5A.1, 5A'.1) compared to the medial chambers (5A.2, 5A'.2). A baby B is also shown in this figure, as positioned longitudinally to said lateral (5A.1, 5A.1) and medial (5A.2, 5A'.2) chambers.

[0143] Particularly advantageously, the M mattress may have an additional layer of IV protection. This IV layer serves to isolate the baby from the inflatable elements, and it is either manufactured separately from the M mattress or, alternatively, integrated into said M mattress.

[0144] In Figure 5, the inflatable chambers (5A.1, 5A'.1, 5A.2, 5A.2) are shown in the deflated state. Thus, the system is slightly raised on the edges M3 of said mattress M, so that the baby B is held in position, limiting the risks of lateral mobilization, therefore of turning over, of said baby B.

[0145] In Figure 6, the inflatable chambers (5A.1, 5A'.1, 5A.2, 5A.2) are shown in the inflated state. Thus, the system is greatly raised on the edges M3 of said mattress M. Indeed, the inflation amplitude of the lateral chambers (5A.1, 5A.1) can be up to 15cm, while the maximum amplitude of the medial chambers (5A.2, 5A.2) can be up to 5cm. In addition, the inflation volume of said lateral chambers (5A.1, 5A.1) is greater than the inflation volume of the medial chambers (5A.2, 5A'.2). Thus, the mattress M forms a "cocoon" around the baby B, almost entirely surrounding it.

[0146] This allows the baby to be held in position within the system. This support is particularly advantageous during operation of the inflatable system, i.e. during the inflation and / or deflation phases of said system. The addition of the difference in volume and amplitude of the lateral chambers compared to the medial chambers, as well as the successive inflation of said lateral chambers then of the medial chambers, improves the stability of the baby and its maintenance within the system.

[0147] Another advantage exists when transporting the baby. In fact, the inflation of the side chambers (5A.1, 5A'.1) alone (which can be provided, in particular, by programming the inflatable system specifically for transport in a motor vehicle, for example), allows for an additional obstacle of approximately 15 cm high around the baby, which promotes its protection and limits the risk of falling, or of the baby being overturned, in particular in the event of an accident. Additional protections, such as harnesses or straps, can also be provided to reinforce the protection of the baby when moving.

[0148] Figures 7 and 8 are diagrams showing the inflation and deflation of the inflatable element of the first zone according to the invention.

[0149] In these figures, only part of the inflatable system 1 is shown in the mattress M, comprising only the inflatable element 3A of the first zone 3. This inflatable element 3A is attached to the control and inflation module 7 by means of the inflation conduit 3B and the deflation conduit 3C, which respectively allow the entry and exit of fluid into or from said element 3A.

[0150] The inflation of the inflatable element 3A (figure 7) is carried out as follows. a. First of all, this inflation involves the opening of the valve 7C positioned at the inlet of the inflation conduit 3B, and the closing of the valve 7C positioned at the outlet of the deflation conduit 3C. The control of the valves 7C is advantageously carried out by the control and inflation module 7, and, more preferably, by the microprocessor included in said module 7 (this microprocessor not being shown in figure 7). The closing of the valve 7C positioned at the outlet of the deflation conduit 3C makes it possible to prevent leakage of the fluid towards the outside of the inflatable element 3A, and therefore allows it to inflate properly. b. Then, activation of the pump is necessary to allow fluid to enter the inflatable element 3A. This pump, not shown in this figure, is preferably positioned upstream of the inflation conduit 3B.

[0151] The deflation of the inflatable element 3A (figure 8) is carried out as follows. a. First of all, this deflation involves the closing of the valve 7C positioned at the inlet of the inflation conduit 3B, and the opening of the valve 7C connected to the outlet of the deflation conduit 3C. The control of the valves 7C is advantageously carried out by the control and inflation module 7, and, even more preferably, by the microprocessor included in said module 7 (the microprocessor not being shown in figure 8). The valve 7C, located at the deflation conduit 3C, therefore has an open position putting said conduit in the open air during deflation. The closing of the valve 7C positioned at the inlet of the inflation conduit 3B makes it possible to prevent the entry of fluid into the inflatable element 3A. b. Then, two variant embodiments are possible. In a first variant, activation of the pump allows fluid to exit from the inflatable element 3A.This pump, not shown in this figure, is in this case preferably positioned both upstream of the inflation duct 3B and downstream of the deflation duct 3C. Preferably, the pump is connected to the deflation duct and is controlled by the module. The pump allows active deflation of the inflatable element 3A. It is also possible for two separate pumps to be used, to inflate or to deflate said element 3A. In a second variant, the deflation of the inflatable element 3A is done passively, that is to say that no pump is activated to carry out the deflation. In this variant, the simple opening of the valve 7C positioned at the level of the deflation duct 3C will allow. the outlet of the fluid from the inflatable element 3A, the fluid then being eliminated into the fluid circuit.

[0152] Advantageously, the inflation and deflation of the first zone 3 shown in Figures 7 and 8 are carried out at the first frequency, said frequency advantageously being the measured heart rate of one of the baby's parents. Advantageously, the heart and respiratory rates, as well as the respiratory amplitude of the same parent are used, for greater efficiency.

[0153] In an alternative embodiment not shown in these figures, each lateral inflatable element comprises a lateral chamber and a medial chamber, said chambers being separate, therefore do not have a conduit allowing fluid communication between them. Each chamber is connected to the control and inflation module by at least one conduit. More preferably, only one conduit connects the module to the corresponding chamber. Thus, a pump is connected to said conduit, with a valve that opens and closes on command from the microprocessor. The valve is in this case bidirectional, and will allow both the entry and exit of fluid from the chamber. In addition, the operation of the valves and pumps can be carried out according to a frequency determined by the microprocessor.In order to limit the risk of the baby rolling over, and possible incorrect positioning of the baby on the mattress, the inflation of the lateral and medial chambers of the inflatable system can be carried out sequentially, that is to say that the microprocessor will first open the valve of the lateral chambers of the inflatable elements, and activate the pumps to allow their inflation. Then, the microprocessor will open the valve of the medial chambers, and activate the pumps, so as to inflate said chambers. In the same way, the deflation of the chambers can be carried out sequentially, first the medial chambers then the lateral chambers. In this way, the baby is kept on the mattress during the operation of the inflatable system.Alternatively, each chamber may have two conduits, one for fluid inlet and one for fluid outlet, whereby this embodiment may operate similarly to the embodiments described in Figures 3, 4, 7 and 8. Alternatively, a. A single pump can inflate the chambers of the same side inflatable element.

[0154] Similarly, the inflatable element of the first zone can also be connected to the control module and inflatable by a single conduit. The presence of a pump and a two-way valve will allow the said element to be inflated and / or deflated according to the frequency determined by the microprocessor.

[0155] Advantageously, the inflatable system may include a feedback function based on the information received by the sensors and transmitted to the module. Indeed, the baby generally has a defined respiratory rate, recorded in the memory area of ​​the module. When this rate exceeds certain predetermined threshold values, the baby may in particular present pathological phenomena, such as bradycardia, tachycardia, bradypnea, tachypnea, etc. These different threshold values ​​of the baby's respiratory rates are also recorded in the memory area of ​​the module.

[0156] Normally, the pumps and / or solenoid valves of the inflatable system operate according to a first pressure and / or a first flow rate. The first pressure is a pressure at which the fluid is introduced into the inflatable elements, the first flow rate is the flow rate at which the fluid is introduced into said elements. This pressure or flow rate makes it possible to inflate said system according to the heart and respiratory rates of one of the parents. More specifically, the inflation of the first zone is carried out according to the heart rate of one of the parents, and the inflation of the second zone is carried out according to the respiratory rate of the same parent. Thus, the selected pressure and / or flow rate will be optimal values ​​for carrying out the inflation and / or deflation of said system, reproducing the parental frequencies.

[0157] However, in the event that the module detects that the baby's respiratory rate exceeds said threshold value(s) recorded in the memory area, the pumps and / or solenoid valves of the inflatable system are activated simultaneously. They will cause said system to inflate according to a second pressure and / or a second flow rate higher than said first pressure and / or first flow rate. These second pressures and / or second flow rates are preferably maximum pressures or flow rates, allowing a massive influx of fluid into the inflatable elements to lead to rapid inflation (for a duration preferably less than 1 second) of said elements. This inflation aims to stimulate the baby, by causing a shock.

[0158] The invention also relates to a mattress configured to be positioned on a bed and / or a seat, in particular a motor vehicle seat, said mattress comprising an inflatable system according to the invention, with side chambers whose vertical inflation amplitude is between 1cm and 15cm.

[0159] The invention also relates to a use of the inflatable system according to the invention for stimulating the baby. This embodiment requires the use of the various sensors previously described, making it possible to verify the physical, biometric and physiological parameters of the baby installed on the inflatable system. These sensors will in particular be used to determine the heart and / or respiratory rates of the baby. These frequencies are subsequently analyzed, preferably by a microprocessor, which will be able to determine the state of health of the baby, in particular if variations in said frequencies compared to a value pre-recorded in the memory zone are noted.

[0160] When a change in said frequencies compared to the value is noted, and more particularly, when these changes reach threshold values, these values ​​will be "recognized" by the microprocessor as potentially dangerous for the baby, and may result in the activation of an alert mode. This alert mode is characterized by the rapid, maximum and sudden inflation of the inflatable elements, which will stimulate the baby. This stimulation is intended to limit the risks of apnea and / or sudden infant death syndrome, by causing brief and effective stimulation of the baby. This should allow a restoration of the baby's heart rate and / or respiratory rate. In particular, the stimulation could be activated in the event of bradycardia, tachycardia, bradypnea or tachypnea of ​​the baby for example.

[0161] The invention also relates to a use of the inflatable system according to the invention for data analysis, in particular to know the evolution of physical, biometric and / or physiological parameters of the baby, such as the baby's heart and / or respiratory rates. It may be interesting to know the evolution of said parameters following the use of one and / or other of the pre-recorded frequencies, to know which frequencies are particularly effective, and in particular to know whether, after using the alert mode, the baby's heart and respiratory rates have returned to normal, or whether other measures must be taken. In particular, in the case of a pathological event in the baby (bradycardia, tachycardia, bradypnea or tachypnea), especially if this event has not been resolved, it may be interesting to have an alert, to one or other of the parents, to a third party (in particular if the baby is in the hospital), of an audible or vibratory type, or by receiving a notification on a computer or smartphone for example, so that the parents and / or the available medical staff can take care of the baby presenting particular symptoms.

[0162] The invention also relates to a method of helping a baby to sleep or fall asleep, comprising the following steps.

[0163] First, a step of measuring the heart rate of a parent of the baby, followed by a step of measuring the respiratory rate of said parent.

[0164] Then, when the baby is installed on a support, a step of installing the first inflatable zone under the baby's head, then installing the second inflatable zone under the baby's body.

[0165] Finally, a final step of alternately inflating and deflating the first inflatable zone according to a first frequency corresponding to the measured heart rate, and simultaneously alternately inflating and deflating the second inflatable zone according to a second frequency corresponding to the measured respiratory rate.

[0166] Even more advantageously, the breathing amplitudes of the parents can also be known, and used to allow the inflation and deflation of the elements according to the breathing amplitude corresponding to that of the parent for which the heart and respiratory rates have been selected. To this can also be added the warming of the fluid used in the inflatable elements, which should also improve the baby's perception of the presence of the selected parent.

[0167] The arrangement of the various elements and / or means and / or steps of the invention, in the embodiments described above, should not be understood as requiring such an arrangement in all implementations. In any event, it will be understood that various modifications may be made to these elements and / or means and / or steps, without departing from the spirit and scope of the invention.

[0168] Further, one or more features disclosed only in one embodiment may be combined with one or more other features disclosed only in another embodiment. Similarly, one or more features disclosed only in one embodiment may be generalized to other embodiments, even if that or those features are described only in combination with other features.

[0169] The use of the verb "comprise", "comprise" or "include" and its conjugated forms does not exclude the presence of other elements or other steps than those set out in a claim.
