Description

Title of the invention: Device for protecting an epileptic patient

[0001] The present invention relates to a protection device for protecting an epileptic patient.

[0002] The invention relates to the field of manufacturing devices designed to ensure the protection of an epileptic patient, more particularly the head (in particular the face), or even the neck of such an epileptic patient, in the event of a fall during an epileptic seizure.

[0003] Such devices for protecting an epileptic patient are already known.

[0004] Such a device usually includes a helmet and a chin strap to secure this helmet under the chin. Such a device is rudimentary, unattractive and stigmatizing for the patient. In addition, although the chin strap may include a chin guard to protect the lower jaw in the event of a fall, this device does not protect the entire face of the patient who, in the event of a fall, may fracture the bones or cartilage of the face.

[0005] One solution has been to develop a device that includes a helmet and at least one face shield that extends from the helmet and to the front of the patient's face. Such a device may also include a collar that surrounds the neck and is secured to said helmet and / or the face shield. Such a device is even less aesthetic and even more stigmatizing.

[0006] The present invention aims to remedy the drawbacks of the protection devices of the state of the art.

[0007] To this end, the invention relates to a protection device for protecting an epileptic patient in the event of an epileptic seizure. This protection device comprises, on the one hand, at least one physiological parameter sensor configured to record at least one physiological parameter of the epileptic patient, on the other hand, at least one helmet which comprises at least one inflatable cushion which is configured to deploy at least in front of at least one part of the face of the epileptic patient as well as at least one means for inflating said at least one inflatable cushion, and, on the other hand, at least one control means which is configured to control said at least one inflation means, this when said at least one physiological parameter sensor records an appearance or a modification of such a physiological parameter which is characteristic of an epileptic seizure.

[0008] According to another characteristic, said at least one physiological parameter sensor comprises at least one sensor configured to detect perspiration and / or at least a sensor configured to detect an odor and / or at least one sensor configured to detect muscular activity and / or at least one sensor configured to detect cardiac activity and / or at least one sensor configured to detect cerebral activity and / or at least one sensor configured to detect ventilatory or respiratory activity and / or at least one sensor configured to detect ocular activity and / or at least one sensor configured to detect body temperature.

[0009] Additionally, the protection device may further comprise at least one movement sensor configured to detect at least one movement of the epileptic patient.

[0010] Another characteristic concerns the fact that the helmet comprises at least one housing inside which is housed said at least one inflatable cushion and / or said at least one inflation means and / or said at least one control means.

[0011] Yet another feature relates to the fact that said at least one inflation means comprises, on the one hand, at least one compressed gas reservoir and, on the other hand, at least one release means which is configured to release the compressed gas contained in said at least one compressed gas reservoir.

[0012] Thus, the protection device according to the invention comprises, on the one hand, at least one physiological parameter sensor configured to record at least one physiological parameter of the epileptic patient and, on the other hand, at least one means for controlling at least one means for inflating at least one inflation cushion, this when said at least one physiological parameter sensor records an appearance or a modification of such a physiological parameter which is characteristic of an epileptic seizure.

[0013] The protection device therefore advantageously ensures the protection of the epileptic patient (more particularly of the face of this patient) in the event of an epileptic seizure, this on the basis of at least one reading of at least one physiological parameter specific to this patient and characteristic of an epileptic seizure.

[0014] Furthermore, basing the protection of the patient on the reading of at least one physiological parameter sensor of this patient advantageously makes it possible to detect an epileptic seizure or the imminence of such an epileptic seizure well before the patient falls and / or well before a movement sensor (in particular of the accelerometer type) can detect a fall which results from such an epileptic seizure. The protection device according to the invention then advantageously makes it possible to implement said at least one inflatable cushion to protect the patient, in a particularly early, or even anticipated, manner, and before this patient falls, or even before a movement sensor detects such a fall.

[0015] The helmet of the protective device comprises at least one housing inside which is housed said at least one inflatable cushion and / or said at least one means of inflation and / or said at least one control means.

[0016] This advantageously allows the epileptic patient to wear a helmet which, on the one hand and outside of an epileptic seizure, can be aesthetic and little (or not) traumatic and, on the other hand and in the event of an epileptic seizure, ensures protection in the event of a fall. In addition, such a helmet advantageously allows such an epileptic patient to avoid having to permanently wear an unsightly and traumatic helmet.

[0017] Furthermore, after an epileptic seizure and after deployment of said at least one airbag, the characteristics of the device (in particular said at least one housing, said at least one airbag, said at least one inflation means) advantageously allow, easily and quickly, folding of said at least one airbag inside said at least one housing, replacement of at least a part of said at least one inflation means in such a housing and / or filling of said at least one inflation means, this to allow quickly and easily a new use of the device.

[0018] Other aims and advantages of the present invention will appear during the description which follows relating to embodiments which are given only as indicative and non-limiting examples.

[0019] Understanding of this description will be facilitated by referring to the attached drawings in which:

[0020] [Fig. 1] represents a schematic and perspective view of a protection device, which is in accordance with the invention, and which comprises at least one inflatable cushion which is folded inside at least one housing which the helmet of this protection device comprises.

[0021] [Fig.2] is a view similar to [Fig.l] and shows the protective device illustrated [Fig.l] in which said at least one airbag is inflated and deployed outside the helmet of the protective device, this at least in front of at least part of the face of the epileptic patient.

[0022] The present invention relates to the field of manufacturing devices designed to ensure the protection of an epileptic patient, more particularly the protection of the head (in particular the face), or even the neck of such an epileptic patient, in the event of a fall during an epileptic seizure.

[0023] This protection device 1 comprises, on the one hand, at least one physiological parameter sensor 2 which is configured to record at least one physiological parameter of the epileptic patient. In fact and according to a particular embodiment of the invention, the protection device 1 comprises a plurality of physiological parameter sensors 2 which are each configured to record at least one physiological parameter of the epileptic patient.

[0024] In this regard, the physiological parameter of the epileptic patient is understood to mean any parameter relating to normal functions and reactions of the body of this epileptic patient.

[0025] Said at least one physiological parameter sensor 2 may then comprise at least one sensor configured to detect perspiration, more particularly to detect perspiration which is characteristic of an epileptic seizure. Such a physiological parameter sensor 2 may then comprise a humidity sensor and / or be in contact with the patient's skin.

[0026] Alternatively, said at least one physiological parameter sensor 2 may comprise at least one sensor configured to detect an odor, more particularly to detect an odor which is characteristic of an epileptic seizure. Such a physiological parameter sensor 2 may then comprise an olfactory sensor configured to detect or detect at least one particular odorant molecule.

[0027] Said at least one physiological parameter sensor 2 may also comprise at least one sensor configured to detect muscular activity (in particular muscular tension or muscular contraction), more particularly to detect muscular activity (in particular muscular tension or muscular contraction) which is characteristic of an epileptic seizure. Such a physiological parameter sensor 2 may then comprise a myoelectric sensor and / or a sensor configured to detect an electrical signal originating from the muscular activity of the epileptic patient.

[0028] Another embodiment consists in that said at least one physiological parameter sensor 2 may comprise at least one sensor configured to detect cardiac activity, more particularly to detect cardiac activity which is characteristic of an epileptic seizure. Such a physiological parameter sensor 2 may then comprise a sensor for detecting the heart rate and / or be in contact with the patient's skin.

[0029] Yet another embodiment consists in that said at least one physiological parameter sensor 2 comprises at least one sensor configured to detect cerebral activity (more particularly a sensor making it possible to establish an electroencephalogram), more particularly to detect cerebral activity which is characteristic of an epileptic seizure. In this regard, it will be observed that the protection device 1 preferably comprises a plurality of physiological parameter sensors 2 which each comprise such a sensor configured to detect cerebral activity.

[0030] Said at least one physiological parameter sensor 2 may also comprise at least one sensor configured to detect a ventilatory or respiratory activity, more particularly to detect a ventilatory or respiratory activity which is characteristic of an epileptic seizure. Such a physiological parameter sensor 2 may, then, include a ventilation noise sensor and / or be in contact with the patient's skin.

[0031] Said at least one physiological parameter sensor 2 may also comprise at least one sensor configured to detect ocular activity, more particularly to detect ocular activity which is characteristic of an epileptic seizure.

[0032] Finally, said at least one physiological parameter sensor 2 may also comprise at least one sensor configured to record a body temperature, more particularly to record a body temperature which is characteristic of an epileptic seizure. Here again, such a physiological parameter sensor 2 may be in contact with the patient's skin.

[0033] According to a particular embodiment of the invention, the protection device 1 comprises a plurality of physiological parameter sensors 2 which comprise at least one sensor configured to detect perspiration and / or at least one sensor configured to detect an odor and / or at least one sensor configured to detect muscular activity and / or at least one sensor configured to detect cardiac activity and / or at least one sensor configured to detect cerebral activity and / or at least one sensor configured to detect ventilatory or respiratory activity and / or at least one sensor configured to detect ocular activity and / or at least one sensor configured to detect body temperature.

[0034] Additionally, this protection device 1 may also comprise at least one movement sensor configured to detect at least one movement of the epileptic patient (in particular a fall of this patient), more particularly to detect at least one movement which is characteristic of an epileptic seizure (in particular a fall due to such an epileptic seizure). Such a movement sensor may then comprise an accelerometer or the like.

[0035] Another characteristic concerns the fact that the protection device 1 may comprise at least one support which comprises said at least one physiological parameter sensor 2 (or even a plurality of these physiological parameter sensors 2) and / or said at least one movement sensor (or even a plurality of these movement sensors).

[0036] In particular, such a support may then comprise said at least one physiological parameter sensor 2 configured to detect perspiration and / or said at least one physiological parameter sensor 2 configured to detect an odor and / or said at least one physiological parameter sensor 2 configured to detect muscular activity and / or said at least one physiological parameter sensor 2 configured to detect cardiac activity and / or said at least one physiological parameter sensor 2 configured to detect ventilatory or respiratory activity and / or said at least one physiological parameter sensor 2 configured to recording a body temperature and / or said at least one movement sensor configured to record at least one movement of the epileptic patient.

[0037] Such a support may take the form of a belt (in particular intended to be positioned around the arm, around the thorax or around the shoulders of the epileptic patient) or a collar (in particular intended to be positioned around the neck of the epileptic patient).

[0038] On the other hand, said protection device 1 comprises at least one helmet 3 which comprises at least one inflatable cushion (4, 4a, 4b) which is configured to deploy at least in front of at least one part of the face of the epileptic patient.

[0039] This helmet 3 then also comprises at least one means 5 for inflating said at least one inflatable cushion (4, 4a, 4b).

[0040] According to a particular embodiment of the invention, this helmet 3 may also comprise said at least one physiological parameter sensor 2 (more particularly said at least one physiological parameter sensor 2 which comprises at least one sensor configured to detect cerebral activity) and / or said at least one movement sensor.

[0041] On the other hand, the protection device 1 (more particularly the helmet 3 that this protection device 1 comprises) comprises at least one control means 6 which is configured to control said at least one inflation means 5, this when said at least one physiological parameter sensor 2 (configured to record at least one physiological parameter of the epileptic patient) records an appearance or a modification of such a physiological parameter which is characteristic of an epileptic seizure.

[0042] In this regard, it will be observed that said at least one control means 6 can be configured to control said at least one inflation means 5, this when said at least one physiological parameter sensor 2 detects the appearance of perspiration and / or an odor which is characteristic of an epileptic seizure.

[0043] Alternatively or additionally, said at least one control means 6 may be configured to control said at least one inflation means 5, when said at least one physiological parameter sensor 2 detects a modification, as the case may be, of the muscular activity (more particularly a muscular tension or contraction) and / or of the cardiac activity and / or of the cerebral activity and / or of the ventilatory activity or of the respiratory activity and / or of the ocular activity and / or of the body temperature which is characteristic of an epileptic seizure.

[0044] Additionally, said at least one control means 6 may also be configured to control said at least one inflation means 5, this when said at least one movement sensor (configured to detect at least one movement of the epileptic patient, more particularly configured to detect at least one movement which is characteristic of an epileptic seizure) reveals such a movement (in particular a fall of this patient), more particularly reveals at least one movement which is characteristic of an epileptic seizure (in particular a fall due to such an epileptic seizure).

[0045] Another characteristic of the protection device 1 consists in that the helmet 3 comprises at least one housing (30, 31, 32, 33, 34).

[0046] It is, more particularly, inside such a housing (30, 31, 32, 33, 34) that said at least one inflation means 5 and / or said at least one control means 6 and / or said at least one inflatable cushion (4, 4a, 4b) is housed in the deflated state.

[0047] Furthermore, and according to a particular embodiment, it is, more particularly, inside such a housing (30, 31, 32, 33, 34) that said at least one physiological parameter sensor 2 (more particularly the sensor(s) configured to detect cerebral activity) and / or said at least one movement sensor is housed.

[0048] Another characteristic concerns the fact that said helmet 3 comprises a front part 35, which is intended to extend in front of and / or above the forehead of the epileptic patient, and which comprises at least one front housing 30, which comprises said at least one housing (30, 31, 32, 33, 34), and inside which is housed, in the deflated state, at least a part of at least one frontal inflatable face cushion 4, which comprises said at least one inflatable cushion (4, 4a, 4b), and which is intended to extend in front of the forehead and / or in front of a part of the face of the epileptic patient.

[0049] Yet another feature concerns the fact that said helmet 3 comprises at least one temporal portion 36, which is intended to extend laterally relative to one of the temples of the epileptic patient, and which comprises at least one temporal housing 31, which comprises said at least one housing (30, 31, 32, 33, 34), and inside which is housed, in the deflated state, at least one part of at least one temporal inflatable face cushion 4a, which comprises said at least one inflatable cushion (4, 4a, 4b), and which is intended to extend in front of a temple of the epileptic patient and / or in front of a part of the face of the epileptic patient.

[0050] According to a particular embodiment, said helmet 3 may comprise a facial housing which comprises said at least one frontal housing 30 as well as said at least one temporal housing 31.

[0051] It will be observed that said at least one frontal face airbag 4 (which is housed inside said at least one frontal housing 30) may be distinct from said at least one temporal face airbag 4a (which is housed inside said at least one temporal housing 31), as illustrated [Fig.l].

[0052] Alternatively, said at least one inflatable cushion (4, 4a, 4b) may comprise, on the one hand, said at least one frontal inflatable face cushion 4 (which is housed inside said at least one frontal housing 30) and, on the other hand, said at least a temporal face airbag 4a (which is housed inside said at least one temporal housing 31). In particular, such an airbag (4, 4a, 4b) may be constituted partly by such a frontal face airbag 4 and partly by such a temporal face airbag 4a.

[0053] In any event, said at least one frontal inflatable face cushion 4 and said at least one temporal inflatable face cushion 4a are configured so that, in the deployed position outside their frontal 30 and temporal 31 housing, they provide protection for the face of the epileptic patient while allowing this epileptic patient to breathe.

[0054] Another characteristic concerns the fact that the helmet 3 comprises a cervical part 37, which is intended to extend behind the cervical vertebrae of the epileptic patient, and which comprises at least one cervical housing 32 which comprises said at least one housing (30, 31, 32, 33, 34).

[0055] Said at least one inflatable cushion (4, 4a, 4b) then comprises at least one part of at least one inflatable neck cushion 4b, which is intended to extend at least partly around the neck of the epileptic patient, and which is housed in the deflated state inside said at least one cervical housing 32.

[0056] Alternatively or additionally, this helmet 3 may comprise an occipital part 38, which is intended to extend to the rear of the occiput of the epileptic patient, and which comprises at least one occipital housing 33, which comprises said at least one housing (30, 31, 32, 33, 34).

[0057] It is, more particularly, inside said at least one occipital housing 33 that at least one part of said at least one inflation means 5 (solution not shown) and / or at least one part of said at least one control means 6 (as visible in figures 1 and 2) and / or at least one part of said at least one inflatable neck cushion 4b is housed, as described above and in the deflated state (solution not shown).

[0058] Additionally, the helmet 3 may comprise a parietal portion 39, which is intended to extend to the rear and / or above the skull of the epileptic patient, and which comprises at least one parietal housing (34) which comprises said at least one housing (30, 31, 32, 33, 34).

[0059] It is, more particularly, inside said at least one parietal housing 39 that at least one part of said at least one inflation means 5 is housed (as visible in figures 1 and 2) and / or at least one part of said at least one control means 6 (solution not shown).

[0060] As regards said at least one inflation means 5, the latter 5 comprises, on the one hand, at least one compressed gas reservoir 50 which may comprise at least one compressed gas cartridge 51. This compressed gas may be compressed air, a compressed neutral gas, compressed inert gas, compressed CO2 or other.

[0061] On the other hand, said at least one inflation means 5 comprises at least one release means 52 which is configured to release the compressed gas contained in said at least one compressed gas reservoir 50, this with a view to inflating said at least one inflatable cushion (4, 4a, 4b).

[0062] In this regard, it will be observed that such a release means 52 may comprise at least one solenoid valve, which completes said at least one compressed gas reservoir 50, and which is controlled by said at least one control means 6.

[0063] According to another embodiment, such a release means 52 may comprise at least one striker 53, which is configured to strike a cover which closes said at least one compressed gas reservoir 50, and which is controlled by said at least one control means 6, this to release the compressed gas contained in said at least one compressed gas reservoir 50. Such a striker may be of the pyrotechnic and / or electromagnetic type.

[0064] With regard to said at least one control means 6, the latter 6 communicates with said at least one physiological parameter sensor 2 and / or with said at least one movement sensor, this via a wired or wireless connection, in particular radio.

[0065] Additionally, said at least one control means 6 communicates with said at least one inflation means 5, more particularly with said at least one release means 52 (which such an inflation means 5 comprises), in particular via a wired connection.

[0066] According to another characteristic, the protection device 1 (more particularly said at least one control means 6) may also comprise analysis means which are configured to analyze at least one reading taken by said at least one physiological parameter sensor 2 and / or which are configured to analyze at least one reading taken by said at least one movement sensor.

[0067] These analysis means may, in particular, be configured to detect a value of such a reading (in particular a humidity level, an odorant molecule concentration, a heart rate, a ventilation noise, a temperature, an acceleration) which is greater than or less than a determined threshold value which corresponds, more particularly, to the imminence, the appearance or the presence of an epileptic seizure.

[0068] Alternatively or (and preferably) additionally, these analysis means can be configured to detect a form of the signal of such a reading (in particular an electroencephalogram, an electrical signal originating from muscular activity, an electrical signal originating from cardiac activity) which is either different from a determined form (in particular which corresponds to an absence of seizure of epilepsy), either similar or identical to a specific form (in particular which corresponds to the imminence, the appearance or the presence of an epileptic seizure).

[0069] Said at least one control means 6 can then be configured to control said at least one inflation means 5 as a function of the results of analysis, by the analysis means, of said at least one reading taken.

[0070] In particular, said at least one control means 6 may be configured to control said at least one inflation means 5 when the analysis means detect that the value of such a reading (in particular a humidity level, an odorant molecule concentration, a heart rate, a ventilation noise, a temperature, an acceleration) is greater than or less than a determined threshold value (in particular which corresponds to the imminence, the appearance or the presence of an epileptic seizure) and / or that the shape of the signal of such a reading (in particular an electroencephalogram, an electrical signal originating from muscular or cardiac activity) is either different from a determined shape (in particular which corresponds to an absence of an epileptic seizure), or similar or identical to a determined shape (in particular which corresponds to the imminence, the appearance or the presence of an epileptic seizure).

[0071] The analysis means may also be configured to analyze at least one reading taken by said at least one physiological parameter sensor 2, with regard to at least one other reading taken by at least one other physiological parameter sensor 2 and / or by said at least one movement sensor.

[0072] These analysis means can, then and with regard to such another reading (carried out by said at least one other physiological parameter sensor 2 and / or by said at least one movement sensor), be configured to detect an erroneous reading (carried out by said at least one physiological parameter sensor 2) which corresponds, for example, to an artifact or a reading error or to a reading carried out under inappropriate conditions or to a failure of said at least one physiological parameter sensor 2.

[0073] Said at least one control means 6 (which is configured to control said at least one inflation means 5 as a function of the results of analysis, by the analysis means, of said at least one reading taken) can then be configured to prevent the control of said at least one inflation means 5 in the event of detection of an erroneous reading.

[0074] According to a particular embodiment, these analysis means can be configured, on the one hand, to analyze at least one reading taken by at least one physiological parameter sensor 2 which comprises at least one sensor configured to record cerebral activity, this with regard to at least one other reading taken by at least one movement sensor and, on the other hand, to detect an erroneous reading (taken by said ... taken by said at least one physiological parameter sensor 2 which comprises at least one sensor configured to record cerebral activity, this with regard to at least one other reading taken by at least one movement sensor and, on the other hand, to detect an erroneous reading taken by said at least one physiological parameter sensor 2 which comprises at least one sensor configured to record cere at least one sensor configured to detect brain activity) with regard to such another reading (carried out by said at least one movement sensor). Said at least one control means 6 can then be configured to prevent the control of said at least one inflation means 5 in the event of detection of an erroneous reading (carried out by said at least one physiological parameter sensor 2 which comprises at least one sensor configured to detect brain activity) which corresponds to a reading carried out under inappropriate conditions, in particular due to a movement (detected by said at least one movement sensor) of said at least one physiological parameter sensor 2 relative to the head of the epileptic patient.

[0075] Another characteristic concerns the fact that the protection device 1 (more particularly said at least one control means 6) further comprises modification means which are configured to modify said at least one control means 6 (more particularly to modify a means for managing the operation of the device 1 which said at least one control means 6 comprises), this depending on the results of analysis, by the analysis means, of said at least one reading carried out by said at least one physiological parameter sensor 2 and / or by said at least one movement sensor.

[0076] The presence of these modification means makes it possible, advantageously and for an epileptic patient who is equipped with a protection device 1 according to the invention, to improve the accuracy and precision of the detection of an epileptic seizure or the approach of such a seizure, this on the basis of readings, which are specific to this epileptic patient, and which are carried out by said at least one physiological parameter sensor 2 of this patient and / or by said at least one movement sensor of this patient. These modification means then make it possible to improve the protection of this patient.

[0077] Yet another characteristic concerns the fact that the protection device 1 (more particularly said at least one control means 6) comprises at least recording means for recording at least one reading taken by said at least one physiological parameter sensor 2 and / or at least one reading taken by said at least one movement sensor.

[0078] The analysis means (mentioned above) can then also be configured to analyze said at least one reading which is carried out by said at least one physiological parameter sensor 2 and which is recorded by these recording means and / or to analyze said at least one reading which is carried out by said at least one movement sensor and which is recorded by these recording means, this to control said at least one inflation means 5 (in the event of detection of a value or a signal form which corresponds to the imminence, the appearance or the presence of an epileptic seizure, this as described above) and / or to prevent the control of said at least one inflation means 5 in the event of detection of an erroneous reading (this as described above) and / or to modify said at least one control means 6 by the modification means (this as described above).

[0079] It will be observed that it is, more particularly, said at least one control means 6 which comprises said analysis means and / or said modification means and / or said recording means and / or said means for managing the operation of the protection device 1.

[0080] Said at least one control means 6 and / or said analysis means and / or said modification means and / or said means for managing the operation of the protection device 1 may, at least in part, be constituted by software.

[0081] Said at least one control means 6 comprises at least one electronic card 60 which comprises said recording means and / or said analysis means and / or said modification means and / or said means for managing the operation of the protection device 1. This electronic card 60 communicates (wired or wireless, in particular radio) with said at least one physiological parameter sensor 2 and / or with said at least one movement sensor and / or with said at least one inflation means 5.

[0082] Finally, it is, more particularly, the helmet 3 which comprises at least one part of said at least one control means 6, this 6 being, preferably, housed inside said at least one housing (30, 31, 32, 33, 34) which said helmet 3 comprises.
