Definitions
- 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.
- the invention relates to the technical field of systems making it possible to calm an individual, in particular babies (children, infants, whose age is preferably less than 3 years), in particular systems installed in the bed or the cradle of a baby.
- the baby benefits from the presence of a parent, which results in a calming of the baby, a calming manifested by a reduction in his respiratory rate and his heart rate.
- Parental presence is expressed by speech, odors, body heat but also by the transmission of respiratory movements and the parent's heart rate (“kangaroo care”, in English).
- 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.
- any mobilization of an infant during the sleep phases must be carried out safely, that is to say without lateral mobilization risking causing the baby to tip over.
- 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 result from lateral positioning or in ventral decubitus following the turning of the infant.
- Document CN 113208353 A is also known in the state of the art. This document describes a baby cradle comprising two inflatable cushions controlled by an electronic card. These two inflatable bags are inflated and deflated according to a respiratory frequency collected from other babies and pre-recorded in the electronic card.
- the state of the 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 frequency deduced, in a relatively complex manner, from the frequency mother's heart.
- Document CN 107468000A is also part of the state of the art.
- This document describes a cushion configured to calm the baby.
- This cushion includes a layer made up of three inflatable cushions positioned side by side and each simulating a part of the mother's body.
- Airbags are inflated by two or more inflatable units, such as pumps or compressors, controlled by an electronic board.
- the data simulating breathing are configured and pre-recorded, and are determined arbitrarily. Finally, the inflation of an inflatable bag under a baby's body is likely to mobilize the baby's body and cause breathing difficulties.
- 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.
- 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.
- the invention is particularly suitable for a young subject (that is to say 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 heartbeats of a third subject, preferably a parent of the baby, such as his father or mother.
- This invention is intended to primarily provide comfort for the baby, preferably an infant, through the perception of a respiratory rate and/or a heart rate 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 specific electronic control.
- the invention relates to the field of active comfort care by the application of an inflation technique preferably integrated into a physical support, such as a cradle, a bed, a cushion, and preferably being a mattress .
- a physical support such as a cradle, a bed, a cushion, and preferably being a mattress .
- 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 sensors measurement for example.
- the specific assessment is ensured by comparing the baby's biometric, physical or physiological reference measurements to the baby's biometric, physical or physiological measurements obtained during and/or after application of the reproduction of the parent's respiratory and/or heart rates.
- 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 of an infant during the inflation and/or deflation phases of the system.
- the specific inflation structure and electronic control includes an alert mode when respiratory and/or cardiac anomalies are detected in the baby, preferably the infant.
- the baby can benefit from the reproduction of the respiratory and heart rates of one of his parents during his period of sleep with an original vertical mobilization of his mattress without movements likely to endanger his breathing.
- a person can analyze the effectiveness of this reproduction by analyzing the induced modifications in the baby's respiratory and/or heart rates.
- 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 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 pre-recorded and stored in a memory area accessible to said module.
- the inflatable system according to the invention can be designed from known inflatable bags for the protection of passengers in a motor vehicle.
- the inflatable system can be inflated from any type of fluid, more particularly a heat transfer fluid, such as water, air or a gas under pressure for example.
- the support of the inflatable system has an elongated shape, and can be oval or round, and more preferably, parallelepiped in shape.
- the first and second inflatable zones, respectively supporting the head or the body of the baby may have, for example, a parallelepiped, round or oval shape.
- 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 frequency of inflation and deflation 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.
- the pre-recorded respiratory and heart rates of one of the parents are preferably resting respiratory and heart rates.
- the use of both types of heart and respiratory rates of one of the parents, for inflation and/or deflation of the inflatable system makes it possible to improve the calming effect of said system on the baby.
- baby we mean a young subject, preferably a child under three years old, such as, in particular, an infant.
- the term baby will be used in the remainder of the request and may designate, in an undifferentiated manner, any child under three years old, or infant.
- 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 to fall asleep. This is more preferably the father or mother of the baby.
- 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.
- 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.
- controlling the inflation and/or deflation of each element will be easier, since the size of each inflatable element is less important.
- first side inflatable chamber may be designated, for the sake of simplification, by the expressions “first chamber” or “side chamber”.
- second medial inflatable chamber may be designated, for the sake of simplification, by the expressions “second chamber” or “medial chamber”.
- 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.
- 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.
- the average diameter of the medial chambers is advantageously less 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.
- At least one conduit ensures fluid communication between the first chamber and the second chamber.
- 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 that the fluid can diffuse throughout all of the chambers.
- the inflation fluid when inflating a side inflatable element, is introduced from an inflation port opening into the first chamber, so that said first chamber inflates before the second chamber.
- the successive inflation of the first chamber then the second chamber of each lateral inflation element means that the first chambers are always more inflated than the second chambers during operation of the system, therefore allowing the baby to be maintained within said system during operation.
- the inflation port is connected to a pump controlled by the module.
- pump we mean any device capable of allowing the inflation and/or deflation of the inflatable system. Such a pump can in particular be replaced by a compressor.
- the inflation fluid when deflating a lateral inflatable element, is extracted from a deflation orifice opening into the second chamber, so that the first chamber deflates after said second chamber.
- the deflation port is connected to a pump controlled by the module.
- 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.
- the solenoid valve can be replaced by any inflation or deflation valve known to those skilled in the art.
- the first inflation zone comprises at least one inflatable element, when inflating 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 distinct from the inflation conduit.
- the inflation conduit and the deflation conduit may be a single conduit.
- 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.
- said element can form, for example, a partially closed chamber, extending longitudinally so as to form a profile and partially surround the baby's head.
- the inflation conduit is connected to a pump controlled by the module.
- the deflation conduit is connected to a pump controlled by the module.
- the inflation and deflation conduits of the first inflatable zone can be connected by a single pump.
- the deflation conduit is connected to a solenoid valve controlled by the module, which solenoid valve has an open position putting said conduit into the open air during deflation.
- the solenoid valve allows the opening of the deflation conduit, leading to the passive extraction of fluid from the inflatable element.
- 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 inflation and/or deflation of the inflatable system in the event of a change in said frequency.
- 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 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 check 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.
- Measurements of the baby's respiratory and heart rates and their analysis by the microprocessor make it possible to assess 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.
- the module comprises at least one pressure analyzer and/or one stretch analyzer translating the baby's breathing 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 of the data concerning the baby, measured and stored by the module, will eventually allow for feedback on the operation of the system.
- 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.
- control and inflation module is configured to alternately inflate and deflate the second inflatable zone so that variations in volume of the first and second inflatable chambers reproduce the measured variable amplitude of movements respiratory rate of the parent, which amplitude is pre-recorded and stored in the memory area.
- variable amplitude we mean that variations in parental breathing are reproduced by the middle chambers, which makes the system more efficient.
- the second medial inflatable chambers are configured such that their vertical inflation amplitude is between 1 cm and 5 cm.
- the inflation amplitude of the medial chambers is, in a particularly advantageous manner, lower 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.
- the preferred inflation amplitude of the medial chambers is between 1 cm and 5 cm.
- 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.
- 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 , at an amplitude between 1 cm and 15cm.
- fabric we mean a material capable of containing a fluid hermetically and in a sealed manner, to prevent the passage of the fluid into the external environment, whatever the fluid chosen.
- the inflatable elements can be made of plastic or polymer materials.
- the amplitude of 15cm 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 inflation state of said chambers. This improves the baby's lateral stability, in order to limit any risk of rolling over.
- Maximum inflation of the side chambers eventually allows the system to be used to move the baby, particularly 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.
- a respiratory frequency threshold value is recorded in the memory zone
- 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 greater than said first pressure and /or first flow rate, in the case where the module detects that the baby's respiratory rate crosses said threshold value recorded in the memory area.
- the first pressure and/or the first flow with which the module activates the pumps and/or the solenoid valves are “normal” pressure and/or flow conditions, insofar as they will allow inflation and/or the deflation of the inflatable elements constituting the system, when the parents' heart and/or respiratory rates are used.
- the second pressure and/or flow rate are considered, in a particularly advantageous manner, as pressures and/or flow rates, preferably maximum, produced by the module, so as to cause inflation of said system as quickly as possible (in a particularly advantageous manner, the inflation must be carried out for a period of less than 1 second).
- the inflation elements pass from a deflated state to an inflated state, according to a preferably maximum inflation amplitude. Above all, this allows you to stimulate the baby by causing a “shock”, possibly causing a positive reaction to the baby’s respiratory rate. Indeed, one of the objectives of such stimulation would be to potentially allow the baby's respiratory rate to return below threshold values.
- the unit for analyzing and controlling the inflation and/or deflation phases of the inflatable system consists of at least one microprocessor (also called “central computing unit” whose acronym is “UCC”; or in English “central processing unit”, whose acronym is “CPU”), said microprocessor being preferably integrated into an electronic card.
- This microprocessor can be replaced by a device with an equivalent function known to those skilled in the art.
- the microprocessor is connected to the inflatable units and the 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 frequencies and cardiac, and according to the respiratory amplitudes of one of the parents.
- 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, respiratory amplitude) of the baby recorded using the inflatable system.
- This data can be compared with data recorded in the memory area, and possibly allow feedback on the operation of the system.
- the memory area can be any device capable of recording data, such as a memory card or hard drives for example.
- control and inflation module can also include an input/output interface, which can also be mounted on the electronic card, this interface can include a wireless exchange system, using for example Wi -Fi or BluetoothTM, or a wired exchange system.

- the power supply device may comprise a main battery configured to take over in the event of a power supply interruption, during movement of the inflatable system, for example.
- the battery may be the preferred mode of operation, with the power cable then only allowing the battery to be recharged.
- a backup battery can also be present in the control and inflation module, said battery being configured to take over and power the module in the event of emptying of the main battery, if the inflatable system is autonomous for a long period of time, for example.
- the control and inflation module of the inflatable system may include a thermal management device, which measures and controls the temperature of the fluid circulating in the inflatable system.
- this device can include thermistors, heating means such as a radiator, a resistor or other means exercising a function identical or similar to said heating means and known to those skilled in the art.
- This device can also include a component making it possible to measure the temperature of the fluid and to control it so that it is adapted according to the needs of the baby.
- This device could also include cooling means, in the event that the fluid is too hot.
- the module can also include a fluid reservoir, preferably a heat transfer fluid, such as a liquid or a gas.
- a fluid reservoir preferably a heat transfer fluid, such as a liquid or a gas.
- This reservoir may not be present, particularly when the fluid is ambient air.
- 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 respiratory amplitudes of the parent(s). b. Includes a program for analyzing changes induced by parental parameters on the baby's respiratory and/or heart rates. vs. Includes a program for controlling the inflation and/or deflation of the various inflatable elements. d. Includes an alert mode activation program 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 recorded data, 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) .
- the programming can concern one or more of the parents, or even another person.
- 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, allow the movement of fluid from one area to another.
- the inflatable element also includes solid zones positioned between the inflatable zones.
- 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 lower amplitude of the lateral inflatable zones.
- 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.
- individual assembly we mean that the lateral and medial chambers of each lateral inflatable element are not in communication with one another.
- the rooms can be attached to the module via two conduits.
- each chamber may have a single conduit with a bidirectional valve, allowing both the inflation and/or deflation of the corresponding chamber, and a pump allowing this inflation and/or deflation.
- successive inflation of the lateral chambers 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 for holding the baby as mentioned previously.
- the inflatable system can also include one or more microphones configured to broadcast a pre-recorded sound, the microphone(s) (also called microphones) being advantageously installed at the level of the first inflatable zone.
- the activation of the microphones can be complementary or alternative to the inflation system, for example following the measured data of the baby's respiratory and heart rates.
- This sound can, for example, be music or the pre-recorded voice of one of the parents interpreting a text read or a song.
- 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.
- Using a parent's voice helps improve soothing of the baby, particularly when the sensors, and more specifically, the pressure sensors located on the inflatable system record an acceleration in the heart rate and/or the baby's respiratory rate.
- 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.

- 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.
- 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 safety conditions, said conditions including the absence of lateral tilt mobilization of the baby's body and an alert mode initiated according to one or more predefined critical parameter(s).
- s respiratory arrest, bradypnea, tachypnea, cardiac arrest, bradycardia, tachycardia).
- 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 thresholds for bradycardia, tachycardia, bradypnea, tachypnea.
- the alert mode consists of maximum and brutal inflation of all the inflatable elements, therefore in brutal vertical mobilization, so as to stimulate the baby.
- the microprocessor includes a permanent inflation mode ensuring the physical stability (head, thorax and abdomen) of the baby during periods of transport of the latter.
- the hospitalized baby therefore separated from his parents, can benefit from the reproduction of 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.
- a person can analyze the effectiveness of this reproduction by analyzing the induced modifications in the baby's respiratory and/or heart rate.

- respiratory amplitude we mean the extent of the movement of the rib cage when the third party breathes, that is to say the height to which the rib cage rises in relation to its position at rest.
- This respiratory amplitude also applied to the inflation and/or deflation of the inflatable elements (3A, 5A, 5A'), will make it even better to imitate the presence of the selected third party, and to improve the baby's impression of being in the arms of said third party.

- the inflation of the lateral inflatable elements (5A, 5A) of the second zone 5 is carried out as follows. has. First of all, there is opening of the valve 7C positioned at the level of the first conduit (5A.4, 5A.4) of the side 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 7C valves is controlled by module 7, and more particularly by the microprocessor. b. Then, the pump (not shown in this figure) positioned upstream of the first conduit (5A.4, 5A.4) is actuated.
- This actuation is carried out by the microprocessor, and leads to the introduction of inflation fluid from an inflation orifice into the first side chamber (5A.1, 5A.1) of each side inflatable element (5A, 5A).
- the fluid circulates from the lateral chamber (5A.1, 5A.1) towards the medial chamber (5A.2, 5A.2), thanks to the presence of the conduit (5A.3, 5A.3) positioned at the end opposite said chambers (5A.1, 5A'.1, 5A.2, 5A'.2) of the first and second conduits (5A.4, 5A.4, 5A.5, 5A'.5).
- 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) makes it possible to prevent said chambers (5A.1, 5A.1, 5A.2, 5A'.2) to deflate prematurely.
- Figure 4 is a diagram representing the circulation of fluid in the side inflatable elements, during a deflation phase of the inflatable system.
- 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).
- the deflation of the side inflatable elements (5A, 5A') is carried out as follows. has.
- valve 7C positioned at the level of the first conduit (5A.4, 5A.4) of the side chamber (5A.1, 5A'.1), and opening of the valve 7C positioned at the exit of the second conduit (5A.5, 5A.5) from 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 placing said orifice at open air when deflating.
- 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).
- 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).
- the deflation port is connected to the pump.
- Deflation is then carried out actively by said pump controlled by module 7.
- deflation of the lateral inflatable elements (5A, 5A') is carried out passively, by simple opening of 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 pipes mentioned in Figure 2 and not shown in this figure.
- 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 circulates from the lateral chamber (5A.1, 5A'.1) towards the medial chamber (5A.2, 5A.2) thanks to the presence of the conduit (5A.3, 5A.3), is will find itself sucked in by the evacuation of fluid from the medial chamber (5A.2, 5A'.2).
- the medial chamber (5A.2, 5A'.2) will be partially deflated when deflation of the lateral chamber begins. (5A.1, 5A'.1).
- the deflation of the lateral chambers (5A.1, 5A.1) is therefore carried out after the deflation of the medial chambers (5A.2, 5A'.2), first by emptying the medial chambers (5A.2, 5A'. 2) then by emptying the side chambers (5A.1, 5A'.1). Closing the valve 7C positioned at the entrance to the first conduit (5A.4, 5A.4) of the side chambers (5A.1, 5A.1) makes it possible to avoid said chambers (5A.1, 5A.1, 5A.2, 5A'.2) to inflate again.
- the inflation and deflation of the lateral inflatable elements (5A, 5A') presented 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.
- the respiratory frequency is coupled to the use of the respiratory amplitude of said parent, in order to improve the effectiveness of said system.
- FIG. 1 For 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 design of the fluidic circuit different from that mentioned in Figure 2, with an arrival and departure of the fluidic circuit from the pump.
- Figures 5 and 6 are sectional diagrams of the inflatable system according to the invention, on which the baby is positioned.
- the mattress M is shown with only part of the inflatable system according to the invention, more precisely with the lateral (5A.1, 5A'.1) and medial (5A.2, 5A. 2) side inflatable elements of said system.
- These views allow 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.
- the mattress M can have an additional layer of protection IV.
- This IV layer serves to isolate the baby from inflatable elements, and it is either manufactured separately from the M mattress, or, alternatively, integrated into said M mattress.
- the inflatable chambers (5A.1, 5A’.1, 5A.2, 5A.2) are shown in the inflated state.

- 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).
- mattress M forms a “cocoon” around baby B, surrounding him almost entirely.

- 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). Closing the 7C valve positioned at the outlet of the 3C deflation conduit prevents a leak from the fluid towards the outside of the inflatable element 3A, and therefore allows its proper inflation. b. Then, activation of the pump is necessary to allow the entry of fluid into the inflatable element 3A. This pump, not shown in this figure, is preferably positioned upstream of the inflation conduit 3B.
- the deflation of the inflatable element 3A ( Figure 8) is carried out as follows. has. 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 valve 7C, located at the level of the deflation conduit 3C therefore has an open position putting said conduit into the open air during deflation.
- Closing the valve 7C positioned at the inlet of the inflation conduit 3B makes it possible to avoid the entry of fluid into the inflatable element 3A.
- activation of the pump allows the outlet of fluid from the inflatable element 3A.
- This pump not shown in this figure, is in this case preferably positioned both upstream of the inflation conduit 3B and downstream of the deflation conduit 3C.
- the pump is connected to the deflation conduit and is controlled by the module. The pump allows active deflation of the inflatable element 3A. It is also possible that two separate pumps are used, to inflate or deflate said element 3A.
- the deflation of the inflatable element 3A is done passively, that is to say that no pump is activated to carry out the deflation.
- the simple opening of the valve 7C positioned at the level of the deflation conduit 3C will allow the outlet of the fluid from the inflatable element 3A, the fluid then being eliminated in the fluid circuit.
- 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.
- the heart and respiratory rates, as well as the respiratory amplitude of the same parent are used, for greater efficiency.
- 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 attached to the control and inflation module by at least one conduit. More preferably, only one conduit connects the module to the corresponding chamber.
- a pump is attached to said conduit, with a valve which opens and closes on the order of the microprocessor.
- the valve is in this case bidirectional, and will allow both the entry and exit of the fluid from the chamber.
- the operation of the valves and pumps can be carried out at a frequency determined by the microprocessor.
- the inflation of the lateral and medial chambers of the inflatable system can be carried out sequentially, that is to say that the microprocessor goes from First open the valve of the side chambers of the inflatable elements, and activate the pumps to allow them to inflate. Then, the microprocessor will open the valve of the medial chambers, and activate the pumps, so as to inflate said chambers. Similarly, deflation of the chambers can be performed sequentially, first the medial chambers then the lateral chambers. In this way, the baby is held on the mattress while the inflatable system operates.
- each chamber can have two conduits, one for the inlet and the other for the outlet of the fluid, this embodiment can therefore operate in a manner similar to the embodiments described in Figures 3, 4, 7 and 8.
- a only one pump can inflate the chambers of the same side inflatable element.
- the inflatable element of the first zone can also be connected to the control and inflatable module by a single conduit.
- the presence of a pump and a bidirectional valve will allow said element to be inflated and/or deflated according to the frequency determined by the microprocessor.
- the inflatable system can include a feedback function based on the information received by the sensors and transmitted to the module.
- the baby generally has a defined respiratory rate, recorded in the memory area of the module.
- this frequency 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 frequencies are also recorded in the memory area of the module.
- 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 makes it possible to inflate said system according to the heart and respiratory rates of one of the parents. More particularly, 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.
- the pressure and/or flow rate selected will be optimal values for inflating and/or deflating said system, reproducing the parental frequencies.
- the pumps and/or solenoid valves of the inflatable system are activated simultaneously. They will cause inflation of said system according to a second pressure and/or a second flow rate greater than said first pressure and/or first flow rate.
- These second pressure and/or second flow 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, causing a shock.
- 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 amplitude vertical inflation is between 1cm and 15cm.
- the invention also relates to a use of the inflatable system according to the invention to stimulate the baby.
- This embodiment requires the use of the various sensors previously described, making it possible to check the physical, biometric and physiological parameters of the baby installed on the inflatable system. These sensors will be used in particular to determine the baby's heart and/or respiratory rates. These frequencies are then 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 area are noted.
- 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, by causing brief and effective stimulation of the baby. This should allow the baby's heart and/or respiratory rate to recover.
- stimulation could be activated in the event of bradycardia, tachycardia, bradypnea or tachypnea of the baby for example.
- the invention also relates to a use of the inflatable system according to the invention for the analysis of data, in particular to know the revolution 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 or other of the pre-recorded frequencies, to know which frequencies are particularly effective, and in particular to know if, after using the alert, the baby's heart and respiratory rates have returned to normal, or other arrangements need to be made.
- the invention also relates to a method of helping a baby sleep or fall asleep, comprising the following steps.
- the breathing amplitudes of the parents can also be known, and be 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.
- one or more features set forth only in one embodiment may be combined with one or more other features set forth only in another embodiment.
- one or more characteristics presented only in one embodiment can be generalized to other embodiments, even if this or these characteristics are described only in combination with other characteristics.
