Description

Title of the invention: PACIFIER FOR MONITORING A CHILD Technical field of the invention

[0001] The present invention relates to a pacifier for monitoring a child. It aims at the cardio-ventilatory monitoring of the child. It applies, in particular, to the prevention of accidents during sleep such as apneas or hypopneas (respectively interruption or reduction of the ventilatory flow). State of the art

[0002] Monitoring of children, particularly newborns, is often desired by parents to reassure them about their child's safety, health and well-being. This monitoring is usually implemented by means of remote monitoring with a video stream and an audio stream or an audio stream only. This type of monitoring provides only superficial information about the child's health and well-being.

[0003] The implementation of a pacifier equipped with a thermometer is known from the prior art. The information provided by this type of device is however unreliable, because the pacifier is likely to fall or be poorly positioned in the child's mouth.

[0004] No device can provide reliable and rich information on the health and well-being of the child and relay it effectively to parents or a health professional. Statement of the invention

[0005] The present invention aims to remedy all or part of these drawbacks.

[0006] To this end, according to a first aspect, the present invention aims at a pacifier for monitoring the well-being of a child, which comprises: - a nipple shield, - a collar, - a sensor for estimating the value of at least one physiological quantity of the child, - a means of transmitting a signal representative of a physiological quantity of the child and - anchoring means restricting the position of the pacifier in the child's mouth.

[0007] Thanks to these provisions, estimates of physiological quantities concerning the child can be made and transmitted to the parents as part of parental monitoring of the child's well-being. This same information can be transmitted to a remote server or to a terminal accessible to a medical professional as part of monitoring the child's health or as part of treating a pathology.

[0008] By way of example, the pacifier which is the subject of the invention is useful in the context of the non-invasive and early identification or monitoring of Sleep-related Obstructive Respiratory Disorders (abbreviated "SRD") such as Obstructive Sleep Apnea / Hypopnea Syndromes (abbreviated "OSAHS"), associated with a craniofacial anomaly of the mandibular hypoplasia type.

[0009] The pacifier which is the subject of the invention is particularly suitable for monitoring newborns, infants and very young children up to three years of age. It may, however, be adapted to suit older children without departing from the scope of the invention.

[0010] The pacifier which is the subject of the invention comprises anchoring means constraining its position in the child's mouth, thus ensuring quality and continuity of data collected by the sensors. This anchoring has the effect of preventing the risk of the monitoring pacifier being lost by the child or the risk of it ending up in a position unsuitable for the measurement of physiological data by a sensor.

[0011] In embodiments, the anchoring means comprise a notch cut into the collar, constraining the oriented positioning of the notched side of the collar towards the child's nose.

[0012] Thanks to these arrangements, the monitoring pacifier is always oriented in the same way in the child's mouth. So that a sensor can be systematically positioned optimally on the upper part of the pacifier, oriented towards the child's nose and palate, or on its lower part, oriented towards the child's chin and tongue.

[0013] In embodiments, the anchoring means comprise two cords fixed on either side of the collar, each forming a loop configured to be passed around the child's ear.

[0014] Thanks to these provisions, the hold of the monitoring pacifier in the child's mouth is improved. In particular, the cords prevent the risk of losing the monitoring pacifier.

[0015] In embodiments, the pacifier comprises at least one tab, provided with one end secured to the pacifier and another end at the level of the child's nose, configured to facilitate the interaction between the air flow circulating through the child's nostrils and a sensor of at least one physiological quantity of the child.

[0016] Thanks to these provisions, the quality of the measurements made by at least one sensor of at least one physiological quantity of the child is improved.

[0017] In an exemplary embodiment, at least one leg has a sensor on its end close to the child's nose. Preferably, this end is placed at the level of the child's nostril.

[0018] In an exemplary embodiment, at least one tab is at least partly hollow and makes it possible to guide the circulation of the air flow towards a sensor of at least one physiological quantity of the child located on the pacifier or in said tab.

[0019] In embodiments, the pacifier comprises at least one sensor positioned on the nipple and configured to estimate body temperature.

[0020] Thanks to these provisions, the child's body temperature can be estimated. For example, in order to identify a fever. The positioning of the sensor on the teat allows for reliable temperature measurement in the oral cavity.

[0021] In embodiments, the pacifier comprises at least one sensor configured to estimate the presence or absence of the pacifier in the child's mouth.

[0022] Thanks to these provisions, the presence or absence of the pacifier in the child's mouth can be estimated. Preferably, an alert is issued in the event of detection of an absence of a pacifier in the child's mouth to allow a parent or a health professional to replace it.

[0023] In embodiments, the pacifier comprises an oximeter.

[0024] Thanks to these provisions, the physiological data relating to the saturation of oxygen or carbon dioxide in the child's blood can be measured.

[0025] In embodiments, the pacifier comprises at least one sensor configured to estimate the ventilation flow rate.

[0026] Thanks to these provisions, the physiological data relating to the quantity of air exhaled or the quantity of air inspired by the child can be estimated. One or more such sensors also make it possible to measure the number, duration and amplitude of the expiration and inspiration phases.

[0027] In embodiments, the pacifier comprises at least one sensor configured to estimate the temperature of the ventilation flow.

[0028] Thanks to these provisions, the temperature variations, measured in the air inspired and expired by the child, make it possible to identify the expiration and inspiration phases.

[0029] In embodiments, the pacifier comprises at least one sensor configured to estimate the ventilation rate.

[0030] In embodiments, the pacifier comprises at least one sensor configured to estimate the heart rate.

[0031] Thanks to these provisions, the physiological data relating to the child's heart rate can be estimated, for example with a view to identifying a heart rhythm disorder.

[0032] In embodiments, the pacifier comprises at least one sensor configured to estimate oral pH.

[0033] Thanks to these provisions, the physiological data relating to oral acidity of the child may be assessed, for example to identify gastroesophageal reflux disease (abbreviated as "GERD").

[0034] In embodiments, the pacifier comprises at least one sensor for estimating the activity of the lingual muscles or at least one sensor for estimating the activity of the labial or perioral muscles.

[0035] Thanks to these provisions, the physiological data relating to the activation of the perioral muscles can be verified and quantified, for example with a view to producing an electromyogram and / or an actimeter. These characteristics allow the measurement of the amplitude of the movements of the tongue and lips and the measurement of their frequency, in particular with the aim of distinguishing between sucking movements and swallowing movements.

[0036] In embodiments, the pacifier comprises at least one sensor for estimating the movements of the pacifier.

[0037] Thanks to these arrangements, the movements of the pacifier resulting from the overall activation of the perioral muscles can be monitored and quantified.

[0038] In embodiments, the pacifier comprises a vibrator controlled based on the estimation of the activity of the lingual muscles or the labial muscles or based on the movements of the pacifier.

[0039] Thanks to these provisions, the pacifier can be made to vibrate in the case in particular where no activity of the perioral muscles has been detected for a certain period of time, to stimulate their activation, as part of a rehabilitation treatment. In addition, the vibration of the pacifier can promote a better hold of the pacifier in the child's mouth by promoting a sucking movement of the teat.

[0040] According to a second aspect, the invention relates to a system for monitoring the well-being of a child which comprises: - at least one pacifier according to the invention, comprising a means for transmitting a signal representative of a physiological quantity of the child, - a portable communicating terminal comprising means for receiving the signal representative of a physiological quantity of the child, display means and means for transmitting an alert when the physiological quantity received exceeds a predetermined threshold.

[0041] Thanks to these provisions, the physiological quantities estimated by the pacifier which is the subject of the invention can be disseminated to the attention of parents or to the attention of a health professional. These provisions also allow a user to order the pacifier which is the subject of the invention, to consult the technical data and to record the estimated physiological quantities, on a local or remote server.

[0042] Certain aims, advantages and particular characteristics of the system which is the subject of the present invention being similar to those of the pacifier which is the subject of the present invention, they are not recalled here. Brief description of the figures

[0049] The present description is given without limitation, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

[0050] It should be noted, from now on, that the figures are not to scale.

[0051] In [Fig.l], which is not to scale, we see a schematic view of a mode of realization of the monitoring pacifier 100 which is the subject of the present invention. In [Fig.2], which is not to scale, we see a schematic sectional view of the monitoring pacifier 100.

[0052] The pacifier 100 comprises a teat 30 which, in normal use, is positioned in the mouth of a child 11, a collar 31 is positioned outside the mouth against the lips of the child 11. A body 32 configured to house electronic components is secured to the collar 31. The pacifier 100 comprises at least one sensor, 76, 78, 81, 82, 83, 84, 86, 88 or 89, for estimating physiological data of the child 11. The pacifier 100 comprises a means for transmitting a signal representative of a physiological quantity of the child, for example a data transmission cable. Preferably, the means of transmitting a signal representative of a physical quantity of the child is a wireless transmitter-receiver, for example an antenna 94. The pacifier 100 further comprises anchoring means 25, 20 and / or 21 constraining the position of the pacifier 100 in the mouth of the child 11.

[0053] In embodiments, the anchoring means constraining the position of the pacifier in the child's mouth comprise: - a notch 25 cut into the collar 31, constraining the oriented positioning of the notched side of the collar 31 towards the nose 14 of the child 11, and / or - two cords, 20 and 21, fixed on either side of the collar 31 and each forming a loop configured to be passed around an ear flap, respectively 12 and 13, of the child 11.

[0054] In embodiments (not shown), the collar 31 includes a cutout of an adjustable size to the dimensions of the child's nose 14.

[0055] In embodiments, at least one cord, 20 or 21, comprises an elastic material allowing a better fit around the ear, 12 or 13.

[0056] In embodiments, illustrated in [Fig.4], the anchoring means constraining the position of the pacifier in the child's mouth comprise a flattened shape of the nipple.

[0057] In embodiments (not shown), the pacifier 100 comprises anchoring means connecting the pacifier to the head of the child 11 and the anchoring means are configured to leave a clearance, of a length less than or equal to the length of the teat 30, between the lips of the child and the body 32 of the pacifier 100. Thus, the anchoring means retain the pacifier 100 when the child 11 drops it by opening the mouth and keep it at a distance short enough for the child to be able to grasp the pacifier 100 with the mouth.

[0058] In embodiments, the pacifier comprises at least one tab, 27 or 28, provided with one end secured to the pacifier 100 and another end at the nose 14 of the child 11. The tabs, 27 and 28, are configured to facilitate the interaction between the air flow circulating through the nostrils of the child 11 and a sensor of at least one physiological quantity of the child.

[0059] In an exemplary embodiment, at least one leg comprises a sensor of at least one physiological quantity on its end at the level of the nose 14 of the child 11. Preferably, this end is placed in direct proximity to the nostril of the child 11.

[0060] In an exemplary embodiment, at least one leg, 27 or 28, is hollow at least in part and configured to guide the circulation of the air flow towards at least one sensor of at least one physiological quantity of the child.

[0061] In embodiments, the tabs, 27 and 28, attached to the pacifier 100 comprise a flexible shape memory material that can be twisted to be placed at the level of the child's nostrils 11 and maintain their position once placed.

[0062] In embodiments, the pacifier 100 comprises a sensor 89 for estimating the intraoral temperature of the child 11, positioned on the nipple 30.

[0063] In embodiments, the pacifier 100 comprises an oximeter 83. For example, the oximeter 83 comprises an infrared radiation emitter oriented towards the pulsatile blood flow and a sensor for measuring the absorption of this radiation.

[0064] The upper part 301 of the teat 30 is defined as the half of the teat oriented towards the nose and palate of the child 11, during normal use of the teat 100. The lower part 302 of the teat 30 is defined as the half of the teat oriented towards the chin and tongue of the child 11, during normal use of the teat 100.

[0065] Preferably, the oximeter 83 is placed on the part of the pacifier 100 closest to the child's tongue, during normal use of the pacifier 100. For example, the oximeter 83 is placed on the lower part 302 of the pacifier 30.

[0066] In embodiments, the pacifier 100 comprises a sensor 84 for estimating the child's ventilation rate or flow. For example, the respiratory rate is estimated from measured data of speed and pressure at the entrance to the nostrils.

[0067] For example, the respiratory flow, that is to say the detection of an inspiration, or an expiration, is estimated as a function of a temperature measured at the nostrils. For example, the sensor 84 is a thermistor positioned on the notch 25 of the collar 31, close to the nostrils of the child 11. For example, the sensor 84 is a thermistor positioned on the tab 27.

[0068] In embodiments, the pacifier 100 comprises a sensor 86 for estimating the ventilation rate of the child 11.

[0069] For example, the sensor 86 for estimating the ventilation rate of the child 11 is a pressure sensor positioned in the leg 28.

[0070] In embodiments, the pacifier 100 comprises a sensor 88 for estimating the heart rate of the child 11. For example, the sensor 88 is an infrared sensor positioned on the pacifier 30. Preferably, the heart rate of the child is extrapolated from the estimated heart rate.

[0071] In embodiments, the pacifier 100 comprises a sensor 81 for estimating the oral pH of the child 11. For example, the sensor 81 is a pH meter positioned on the pacifier 30.

[0072] In embodiments, the pacifier 100 comprises a sensor 82 for estimating the presence or absence of the pacifier 100 in the child's mouth. Preferably, the sensor 82 is one of the sensors already described previously, the measurement of which is used to estimate the presence or absence of the pacifier in the child's mouth. For example, when no respiratory flow, no heart rate or no respiratory flow is detected, an alert is sent to the portable terminal com communicating with the probable reason being the positioning of the pacifier outside the child's mouth.

[0073] In embodiments, the pacifier 100 comprises at least one sensor for estimating the activity of the lingual muscles or the labial muscles.

[0074] For example, the sensor for estimating the activity of the lingual muscles comprises a pair of electrodes 76 placed on the teat 30, in contact with the child's tongue, during normal use of the pacifier 100. In other embodiments, the sensor for estimating the activity of the lingual muscles comprises a pressure sensor placed on the teat 30.

[0075] For example, at least one sensor for estimating the activity of the labial muscles comprises a pair of electrodes 78 placed on the collar 31, in contact with the child's lips, during normal use of the pacifier 100. In other embodiments, the sensor for estimating the activity of the labial muscles comprises a pressure sensor placed on the nipple 30.

[0076] In embodiments, the pacifier 100 also comprises at least one sensor for estimating the movements of the pacifier 100 to identify activation of the perioral muscles. This may be an accelerometer integrated into the collar 31.

[0077] In embodiments, the pacifier 100 comprises a vibrator 95 and a means for controlling the activation of the vibrator 95 based on the estimation of the activity of the lingual muscles or the labial muscles or based on the estimation of the overall movements of the pacifier. For example, the vibrator 95 is an eccentric mass driven in rotation by an electric micromotor and the control means is a microprocessor 91.

[0078] In embodiments, the strength and frequency of the vibrations of the vibrator 95 are controlled by a communicating portable terminal, based on the estimation of the activity of the muscles or the movements of the pacifier or independently of the estimation of these data.

[0079] In embodiments, the operation of the sensors 81, 82, 83, 84, 86, 88, 89, 76 and 78 is controlled by the microprocessor 91. The microprocessor 91 can also implement a means for determining physiological quantities which are not directly measured, but extrapolated from measured data. For example, the determination means is a calculation algorithm. The determination means can also be transferred to a local or remote server.

[0080] In embodiments, the pacifier 100 comprises a memory 92 configured to store at least part of the measured data or any other information useful for the operation of the pacifier 100. The memory can also be transferred to a local or remote server.

[0081] The memory 92 is used in particular to store the data recorded when the connection, WiFi or Bluetooth, is unavailable or lost.

[0082] The pacifier 100 comprises a means for transmitting a signal representative of a physiological quantity of the child. Preferably, the means for transmitting a signal representative of a physiological quantity of the child is a wireless transmitter. For example, the wireless transmitter is an antenna 94 configured to transmit a signal representative of a quantity estimated by one of the sensors of the pacifier 100 or to transmit a signal representative of information relating to the pacifier 100, for example its battery level. Preferably, the wireless transmitter is a transceiver also configured to receive a signal representative of a command in order to transfer it to the microprocessor 91 or to another electronic component of the pacifier 100.

[0083] In embodiments, the wireless transmitter is an antenna 94 operating according to the IEEE 802.11 standard known as “Wi-Fi” or configured to transmit or receive information according to Bluetooth technology (registered trademark) or according to a radio frequency identification (RFID) communication protocol. Preferably, the antenna 94 exchanges information with a Wi-Fi network, or with a smart portable terminal.

[0084] Wi-Fi, Bluetooth and RFID antennas are widely detailed both in the prior art and in reference works in the field, their implementation or operation details are therefore not repeated here.

[0085] In embodiments, the pacifier 100 further comprises an electrical power source 93, for example a battery. In other embodiments, the electrical power source 93 is a rechargeable battery. In other embodiments, the pacifier 100 is connected to an external power source by an electrical cable.

[0086] In [Fig.3], we observe a system 500 for monitoring the well-being of the child which comprises at least one monitoring pacifier according to the invention. The system 500 comprises a wireless transmitter configured to emit a signal representative of a physiological quantity of the child.

[0087] The pacifier 100 is configured to send the signal representative of physiological data of the child to a communicating portable terminal, for example to a tablet 51 or to a smartphone 52. The communicating portable terminal, 51 or 52, comprises a display means.

[0088] The pacifier 100 and / or the communicating portable terminal, 51 or 52, comprise means for transmitting an alert when the physiological quantity received exceeds a predetermined threshold. In embodiments, during an alert, the pacifier 100 and / or the communicating portable terminal, 51 or 52, emit a visual, audible or silent alarm, or display a predetermined physiological data on the means display.

[0089] For example, the alarm takes the form of a ringing tone emitted by the communicating portable terminal, 51 or 52, a vibration, a notification or a written message simply displayed or transmitted by a messaging service.

[0090] The estimates of the physiological magnitudes of the child are recorded locally in the memory of the pacifier 100 or accessible in a memory of the communicating portable terminal, 51 or 52, connected by a wireless communication protocol, for example Bluetooth or Wi-Fi (registered trademarks).

[0091] In embodiments, these same recordings can be copied to a remote computer server 55, connected to the communicating portable terminal via a wired link or via a data network of the Internet or cellular network type.

[0092] The remote server 55 comprises means for receiving the signal representative of at least one physiological quantity of the child.

[0093] In embodiments, the monitoring system 500 comprises a terminal 57 accessible to a healthcare professional connected to a remote computer server 55, or to the communicating portable terminal, 51 or 52, via a wired link or via a data network of the internet or cellular network type.

[0094] Preferably, the data displayed on the terminal 57 accessible to a healthcare professional will be more detailed, with a history of the evolution of the recorded physiological parameters.

[0095] [Fig. 4], which is not to scale, shows a schematic view of a particular embodiment of the pacifier 200, the subject of the present invention. The pacifier 200 is shown in a top view, in the mouth of a child whose lip 18 and the dental arch in formation 15 are shown.

[0096] In [Fig.5], which is not to scale, we see a schematic cross-sectional view of the pacifier 200, in position in the mouth of a child 11. The cross-sectional plane shown in [Fig.4] corresponds to a median sagittal plane of the skull of the child 11, perpendicular to that of the previous figure.

[0097] The pacifier 200 comprises a teat 230. A collar 231 is positioned outside the mouth and abuts against the lips 18 of the child to prevent the risk of ingestion of the pacifier 200. The teat 230 is secured to a pacifier body 232. A weight 235 is removably attached to the body of the pacifier 232.

[0098] The child 11 grips the teat 230 using his lingual and labial muscles and in particular by compressing the teat 230 between his tongue 16 and his palate 17.

[0099] The force of sucking linked to the pressure of the tongue 16, against the palate 17 and the pressure of the lips 18 on the narrow part of the teat 200 as well as the contraction of the elevator muscles of the mandible will allow the teat 200 to be held in the mouth. of the child.

[0100] Observed along a horizontal section plane, as illustrated in [Fig.4], the teat 230 comprises an isthmus 237, that is to say an elongated part of smaller dimension, at the passage of the lips 18 and a part 238 flared to occupy the space formed between the palate 17 and the tongue 16.

[0101] Preferably, the surface area of ​​the part 238 of the teat 230 is greater than or equal to two thirds of the surface area of ​​the palate 17.

[0102] Preferably, at least one dimension of the teat 230, according to the horizontal section plane of the teat, is complementary to a dimension of the dental arch in formation 15 or of the palate 17 of the child 11 wearing the teat.

[0103] In embodiments, the portion 238 of the teat has a general shape of a solid and concave "U" whose concave face is oriented towards the tongue 16 and the convex face is oriented towards the palate 17.

[0104] It is clearly understood, by consulting [Fig.4], that the teat 230, observed along a vertical section plane, is not very thick. The profile of the teat is preferably thin and does not have a significant bulge.

[0105] For the purposes of the invention, the vertical plane of the pacifier 200 is the plane corresponding to the median sagittal section plane of the head of the child 11, when the pacifier 200 is positioned in the mouth of the child 11, during normal use.

[0106] In embodiments, the length ratio between the thickest portion and the thinnest portion of the teat 230, measured on any vertical sectional plane of the teat 200, is between 1 and 5. In embodiments, this ratio is between 1 and 3.

[0107] The flattened shape of the teat 230 described above is an anchoring means, which improves the hold of the teat 200 in the mouth of the child 11, whatever the position of the child 11. In particular, the shape of the teat 230 ensures the correct positioning of the teat in the mouth.

[0108] The flattened shape of the teat 230 causes increased pressure of the tongue 16 of the child 11, against its palate 17. Thus, the quality of the measurements taken by certain sensors, in particular those positioned on the teat 230 is improved.

[0109] Due to this shape of the teat 230, the pressure of the lips 18 on the narrow part of the teat 200 as well as the contraction of the elevator muscles will be increased, contributing to better maintenance of the teat 200 in the child's mouth.
