Description

Warning device and method for defibrillator

Field of the invention

The present description relates to a warning device and method for a cardiac defibrillator and, more specifically, for an automated external defibrillator (AED).

Prior art

Cardiac defibrillation is a technical gesture allowing to restore to normal the anarchic rhythm of the beating of the heart of a person affected by a ventricular tachycardia or a ventricular fibrillation causing a cardiac arrest quickly resulting in the death of the victim without gesture carried out .

Cardiac defibrillation is a technical gesture which consists in sending a biphasic electrical current through the heart in order to restore normal electrical activity. This defibrillation is necessary in certain serious arrhythmias such as ventricular fibrillation as well as ventricular tachycardia causing cardiac arrest.

In the context of cardiac arrest, if nothing is done in the first few minutes, the person's chances of survival are almost nil. Each minute lost represents a loss of 10% of the chances of survival. Cardiac arrests are the cause of approximately 12% of deaths in Europe, including 45,000 people on average per year in France, and 500 in the Grand Duchy of Luxembourg.

Defibrillation involves briefly and voluntarily passing an electric current through the person's heart using a medical device called a defibrillator. Defibrillators generally operate on batteries in order to be mobile. They are made up of at least an electric block making it possible to deliver an electric current calibrated in duration, shape and intensity, a means of transmitting this electric current to a person, for example two flat electrodes, ideally covered with a conductive gel, which is stuck on the person's chest.

Many urban and rural settings today provide for the installation of Automated External Defibrillators, or AEDs, which are generally semi-automatic or fully automatic type defibrillators. A semi-automatic AED is a defibrillator configured to deliver an electric shock when its programming identifies that such shock is needed and by manual initiation by a user upon demand from the device. A fully automatic AED delivers the electric shock directly without user intervention.

Regardless of the type of AED, it is usually configured to provide voice assistance to the AED user to guide them through the steps of using the device. Decree No. 2007-705 of May 4, 2007 relating to the use of automated external defibrillators by non-physicians and amending the public health code allows anyone, regardless of age, to use an AED .

It is estimated that in geographical areas where the installation of AEDs is widespread, the survival rate of people suffering from cardiac arrest can reach 20 to 30%.

In this context, a difficulty encountered is to shorten as much as possible the time between the moment when a person suffers from a heart disorder and the moment when an electric shock can be delivered to him using a AED, in order to maximize the person's chances of survival.

To this end, various devices and processes are known to facilitate the location, access and therefore the use of AEDs located in a given geographical area.

A first example of the prior art is provided by European patent EP 3 402 569 B1, which describes an AED monitoring system. There illustrates a corresponding system 602a configured to monitor the status and availability of a remote DAE 100a. The system includes several main components in addition to the AED 100a, in particular a monitoring device 300a equipped with a sensor 304a that can be used to detect one or more parameters coming from a warning box 122a. Sensor 304a sends a signal to processor 306a which in turn provides a status signal to wireless transmitter 604a. Wireless transmitter 604a is a standard communication device that has software configured to execute instructions and transmit AED status information on a periodic basis or as needed.

Such a system makes it possible to know the availability and the location of an AED, to then communicate this information. Upon receipt of this information, a service provider may take necessary corrective action.

A second example of the prior art is Japanese patent JP6616097 B2, which describes a system for updating position and identification information of an AED so that this information does not depend on the model or type of DAE. Patent JP6616097 B2 also describes a system and a method for searching for a box comprising an AED, this method being implemented using a mobile terminal, a server and a communication network to determine AED location and identification information.
Disadvantages of the prior art

However, the known systems, devices and methods have several disadvantages.

Indeed, a limited number of AEDs distributed in a large geographical area greatly increases the time required for a user to locate a usable AED, and then bring it to the place where a person suffering from a cardiac disorder needs rapid intervention, reducing the person's chances of survival.

In addition, when people trained or able to implement cardiac defibrillation are already near a victim of a cardiac disorder, they are not informed effectively and quickly of the exact location of an AED that can be used in their entourage, sometimes in the same street or in the same building, for example due to poor signage of it.

Under certain circumstances, the instructions for use of AEDs can also be difficult to follow, leading to loss of time to carry out an adequate cardiac defibrillation, thus reducing the chances of survival of the victims.

Finally, AEDs that are easily located on the public highway are sometimes unusable, for example due to voluntary or involuntary damage, power supply faults, and are sometimes even stolen.

There is therefore a need to improve the known systems, devices and methods. The present inventions in at least one embodiment aim to overcome the drawbacks of the state of the art and to make improvements.
Objectives of the invention

In order to respond to this or these drawbacks, it is proposed according to a first object hereof a warning device for an Automated External Defibrillator, AED, located in a predetermined geographical area, said device comprising: - a signaling module configured to emitting a signal perceptible to an individual, said signal warning of the presence of the AED; - a processor functionally connected with said signaling module and with a telecommunications module, said processor being configured to activate said signaling module upon receipt, by said telecommunications module, of an identification request sent by a server; and - said telecommunication module, configured to send a respective acknowledgment message to said server upon receipt of said identification request.

This makes it possible to improve the relationship between a victim of cardiac arrest and a person capable of intervening who is located near this victim. This also allows this person intervening to be more easily informed of the presence and location of an AED at a given distance. This connection, which can be controlled remotely, is also made faster and more efficient.

In an advantageous embodiment, the telecommunications module is a transceiver, the receiver of the telecommunications module being constantly activated in order to ensure a permanent connection to the device in all circumstances.

The transmitter of the transceiver can be activated and deactivated at will upon receipt of a corresponding command by the telecommunication module, with the advantage of being able to deactivate it in certain modes of use in order to save the energy used by the device. In this case, the processor is configured to activate the signaling module and/or the transmitter of the telecommunications module upon receipt of a manual command or an identification request sent by the server.

In one embodiment, the device comprises a casing, said casing comprising the signaling module, the processor and the telecommunications module, an outer face of the casing being provided with a two-dimensional code.

This makes it possible to provide protection for the elements that comprise the device against external conditions, for example weather conditions, theft or damage.

In one embodiment, a reading of said two-dimensional code by a geolocatable user equipment, EUG, triggers a supply, by the telecommunications module, to said EUG, of intervention information from the place of the intervention requiring the setting up of a defibrillator.

In an alternative embodiment to the previous embodiment, a reading of said two-dimensional code by a geolocatable user equipment, EUG, triggers a supply, by the server, to said EUG, of information relating to the place of intervention (time in minutes on foot and by car)

In both of the foregoing embodiments, the defibrillation response information includes a link to a website, an AED availability status, a location of a nearby AED, or a route to a response location. of defibrillation.

In the present, the website to which the link directs is for example the website of the French Association of First Responders.

In one embodiment, the exterior face also includes the recommendations in terms of defibrillator signaling.

In one embodiment, the telecommunications module is further configured to incorporate AED location, AED presence information, and/or AED activity status into the transmitted acknowledgment message.

For example, AED location, AED presence information, and/or AED activity status is stored in device memory.

This allows additional information that improves the AED's warning to be communicated by the server to an EUG.

In one embodiment, the telecommunications module is adapted to be connected to the server and/or to the EUG.

This makes it possible to provide a direct link between the device and a service provider in order to improve its warning, handling or management. This also makes it possible to provide a direct link between the device and the wearer of user equipment, for example a smartphone, and therefore to improve the exchange of information in an urgent situation.

Optionally, upon receipt of the transmitted acknowledgment message from the server, the server is configured to transmit AED location, AED presence information, and/or AED activity status embedded in the message. acknowledgment sent to geolocatable user equipment.

In one embodiment, the telecommunication module is adapted to be connected to the server and/or to the EUG, said connection is implemented by means of a wired connection, a wifi connection, a Bluetooth connection, an LTE connection, a 4G connection, a 3G connection and/or a 2G connection.

This makes it possible to provide additional connectivity, possibly requiring the EUG to subscribe to a mobile data subscription.

In one embodiment, the signaling module comprises a loudspeaker adapted to emit an audible message, a warning light, an optical sensor and/or a display device.

In one embodiment, the loudspeaker comprises an audio amplifier, for example a 10 Watt mono amplifier with a time-datable and/or adjustable sound volume between 85 dBA and 95 dBA. This facilitates the transmission of a voice sound message to a nearby user as well as the sound signaling and therefore the warning of the presence of a cardiac arrest near the defibrillator.

For example, the sound message is a pre-recorded voice message inviting anyone nearby to go to a dedicated page by flashing the QR code present or to contact an emergency number in order to retrieve the necessary information to take the DAE where needed. This message can be changed by uploading a new message.

In a particular embodiment, the warning light comprises a light-emitting diode flashing light, for example a class 1 very high luminosity R65 flashing light. AED passing close to the device.

In a particular embodiment, the optical sensor includes an optional camera module. This improves the protection of the AED by video against inappropriate use, damage or theft. Preferably, the optical sensor comprises or is connected to a memory having a storage capacity greater than 16 GB.

In a particular embodiment, the device or the optical sensor is connected to a motion sensor at the level of the defibrillator. This allows the camera to be triggered if the AED moves

In a particular embodiment, the display device is configured to show any user how to use the AED or to indicate a route to a location where use of the AED is required. Said display device is for example a touch screen or an electronic paper type screen in order to save the energy of the device during its use.

In one embodiment, a remote activation or deactivation of the signaling module or of certain of its elements is implemented remotely by the server. An update of the parameters of these elements, for example the type of sound message that can be emitted by the loudspeaker, can also be carried out remotely.

Each of these achievements improves the effectiveness of warning anyone standing near the device of a possible cardiac arrest reported in a close area.

These embodiments also make it possible to provide a system capable of effectively warning a user of an EUG that a defibrillator is required in the context of a cardiac arrest, this warning providing optimal guidance of the user towards a position where a AED usable for this purpose then to the position where this cardiac defibrillation must be implemented.

This also promotes the use of AEDs by people capable of implementing cardiac defibrillation and by people who are victims of cardiac disorders reported to a centralized server.

In one embodiment, the server is further configured so that the transmission of the availability request, and/or the provision of the trajectory to the current EUG are implemented iteratively for a predetermined time interval, until upon receipt, by the server, of a stop command by the emergency services or by the managers of the application.

In one embodiment, the stop command is triggered when a reading of the two-dimensional code by an EUG is implemented with acceptance of the intervention.

This allows blocking access to other AEDs. It is thus possible to avoid sending more than one AED to the first position, i.e. to avoid offering access and routing of several AEDs to the same place where a cardiac arrest occurs.

Thus, it is possible to alert or warn all the boxes located in a given geographical area. Furthermore, this makes it possible to provide an alert or warning process in which the acceptance of an intervention by an EUG user, by sending a positive acknowledgment to a corresponding availability request , triggers a command to stop warning other AED devices that are located in said geographical area.

In one embodiment, the server is further configured to select the optimal DAE(s) located in a predetermined geographical area for each box.

This makes it possible to define a geographical area that takes into account the distance of one or more devices or boxes from an emergency service. This allows, for example, access to AEDs located 300 meters from a cardiac arrest in urban areas and 1 kilometer in rural areas.

According to another object hereof, there is provided a warning method for an Automated External Defibrillator, AED, in a predetermined geographical area, the method comprising:
- receive, by a server, an alert message provided by a terminal;
- Upon receipt of said alert message, transmitting an identification request from the server to a telecommunications module of at least one warning device located in said predetermined geographical area;
- on receipt, by the server, from said warning device, of a respective acknowledgment message, activating, via a processor which the device comprises, a signaling module which the device comprises to emit a signal perceptible by an individual, said signal warning of a presence of the AED, said processor being functionally connected with said signaling module and with said telecommunications module.

In one embodiment, the method further comprises a step of deactivating the signaling module upon receipt, by the server, of a stop command.

In one embodiment, the stop command is sent to the server after a predetermined period of time, for example 4 or 5 minutes. The stop command can also be sent to the server by the terminal or by an EUG located near the device.

In all present, a situation "in proximity" between two elements is defined so that the distance between these two elements is of the order of a few meters, and preferably less than thirty meters.

According to yet another object hereof, there is proposed a means of storing information, removable or not, partially or totally readable by a computer or a processor comprising code instructions of a computer program for the execution of each of the steps of the method according to any one of the preceding embodiments.

According to yet another object hereof, a computer program is proposed comprising instructions for implementing the method according to one of the preceding embodiments, when said instructions are executed by a processor of a computer processing circuit.

Detailed Description of Embodiments of the Invention

The drawings and the description below contain, for the most part, certain elements. They may therefore be used to better understand this disclosure and to contribute to its definition, where applicable.

Reference is now made to the , which represents a warning system for various AEDs, including an AED 10 located in a predetermined geographical connection zone Z.

As illustrated, a geographical zone Z comprises for example three devices 100, 120 and 140, said geographical zone Z also covering the position of a terminal T. This terminal T is a standard communication device able to communicate with a server 200, this communication equipment being used by a user U to signal the need for cardiac defibrillation at a first position P1.

As an option, the geographical zone Z also covers the position of the server 200. The server 200 is for example an emergency services server. The geographical area can also cover the position of other servers, for example such a separate emergency services server from server 200.

In addition, the communication equipment can also be used to report a position of server 200 or another server. According to different options, the server 200, the terminal T and/or said other server are able to communicate with each other.

For example, the user U is an emergency service, reachable for example at the telephone number "15" or "18" in France, and which is contacted via a telephone call by a person near a victim of a stop cardiac located in the first position P1. In response to this call, the user U, for example the emergency service, triggers a rescue intervention to help the victim and, simultaneously, communicates with the server 200 to trigger a warning for the AEDs located in the area Z. The communication with the server 200 comprises a transmission of information relating to the cardiac arrest, including the first position P1.

The signaling of this cardiac arrest and the warning for said AEDs is implemented via the sending, by the terminal T, of an alert message RQ-M intended for the server 200 that the system includes. This sending is preferably preceded by the communication with the server 200 previously described.

According to a preferred alternative, the sending of the RQ-M alert message is preceded by a preliminary step of signaling a cardiac arrest to the server 200. In particular, this preliminary signaling step comprises the sending of a message signaling such a cardiac arrest and information relating to the cardiac arrest comprising information of the first position P1

An acknowledgment of receipt of this alert message is optionally transmitted to the terminal T (not shown). In the present case, and when the RQ-M alert message is sent to the server 200, three users U300, U301 and U302, respectively carrying EUGs 300, 301 and 302 such as smartphones.

Similar to device 120 located in a position P31 and device 140 located in a position P32, device 100 located in a third position P3, a signaling module 12 such as a loudspeaker configured to emit a sound powerful enough to signal its position to a person in the vicinity of the device 100, a processor 14 functionally connected with this signaling module and with a telecommunications module 16 such as an antenna or a radio frequency transceiver. Near each device is located a corresponding AED. Thus, AED 10 is located near device 100, at least one other AED (not shown) is located near device 120, and at least one other AED (not shown) is located near device 140.

In addition, the processor 14 is configured to activate the signaling module 12 upon receipt, by the antenna 16, of an identification request RQ-ID provided by the server 200 for the attention of at least one devices 100, 120 and 140 located in geographic area Z. Antenna 16 is also configured to send back an ACK-ID acknowledgment message to server 200.

Thus, when the server 200 receives the RQ-M alert message sent by the terminal T located in P1, it implements a communication with the devices 100, 120 and 140 located in the geographical area Z in order to indicate that an AED is required and/or in order to trigger a warning, by said devices in proximity to said same devices.

In particular, the triggered warning of the device 100 comprises the activation of the signaling module 12 that includes the device 100 in order to emit an audible signal or a light signal warning any user located nearby that an AED is necessary for an intervention. rescue. A warning triggering of device 120 and/or 140 is possible simultaneously or offset with the warning triggering of device 100.

Preferably, the warning triggered by the device 100 also includes the activation, by the processor 14 of the device 100, of the telecommunications module 16. In particular, the activation of the telecommunications module 16 takes place upon reception, by said telecommunication, of the RQ-ID identification request sent by a server 200. Upon receipt of the RQ-ID identification request, the telecommunications module can send an ACK-ID acknowledgment message back to the server to confirm that the warning is implemented.

According to a possible variant, a passage of the EUG 300, 301 and/or 302 close to one of the devices 100, 120 or 140 activates at least one module of said device. In particular, said at least one activated module and the signaling module 12 of the device.

According to one embodiment, a reading of a two-dimensional code of one of the devices 100, 120 or 140 by one of the EUGs 300, 301 or 302 triggers, on said EUG, the sending and/or the opening of a web page or an itinerary in the direction of an AED located in the geographical area Z. In particular, the sending and/or the opening of said itinerary can trigger the opening of a module or of an application of geolocation on the EUG. This sending and/or this opening is implemented by the telecommunications module 16 of the device.

This makes it possible, when an individual passes by the device, to suggest to an EUG that this individual is carrying to read the two-dimensional code with his EUG or to transmit to him any useful information with a view to warning of the presence or location of the device. an AED nearby, to intervene in case of cardiac arrest.

If an itinerary is provided to the EUG, this also makes it possible to provide a distance that can be covered on foot or by motorized vehicle to the AED, or even to trigger its GPS to help it get to the place of cardiac arrest.

As an option, when the server 200 receives the RQ-M alert message sent by the terminal T located at P1, it transmits an RQ-D availability request to the EUGs 300, 301 and 302. Thus, in the event of cardiac arrest signaled by the terminal T, each of the users U300, U301 and U302 is alerted and asked about their availability to possibly provide assistance to the person U.

According to different optional and compatible realizations in combination:
- the device 100 or the box 102 is provided with Class II electrical protection to also protect it from faults or electrical accidents;
- To comply with European standards in force, the housing 102 is preferably made of ABS / PC light gray color;
- the box 102 has an IP55 sealing protection index, which further protects it against dust infiltration and low-pressure water jets from any direction;
- the housing 102 has an index of mechanical resistance IK 09, which allows it to withstand an impact of 10 joules;
- The box 102 is fixed to a wall by screwing;
- The device 100 or the housing 102 has a length of between 450 and 550 millimeters, a width of between 450 and 550 millimeters and a height of between 70 and 170 millimeters;
- Preferably, the device 100 or the housing 102 has dimensions of 500 millimeters, 500 millimeters and 120 millimeters;
- An outer face of the housing 102 is provided with a two-dimensional code 104 providing a machine-readable optical format that can be viewed on the screen of a mobile device or printed on paper;
- The outer face is a front face of the case, which is marked in accordance with regulatory signage for AEDs;
- This marking is produced by printing in combination with an anti-ultraviolet treatment to improve the protection of the device when it is placed outside buildings or subjected to the rays of the sun;
- the two-dimensional code is included in this marking; and or
the two-dimensional code 104 is a QR code (“Quick Response” code, in English) readable by an EUG, the reading of the QR code triggering a supply, by the server 200 to the EUG, of intervention information of defibrillation.

In the present, a two-dimensional code is a printable code made up of black square-modules arranged in a square with a white background. In particular, a QR code allows a user equipped with a QR code reader, for example a smartphone, to easily trigger actions such as browsing to a website, for example the website of the French Association of First Responders, downloading a mobile application, indicate a geographical position on a map, watch an online video or multimedia content, connect to a Wi-Fi terminal, initiate a call to a telephone number, for example an emergency number, or send a message.

Advantageously, the reading of the two-dimensional code located on the outer face of the box triggers a connection with the server or a server configured to manage an application for connection with an emergency service, to retrieve the information necessary to take the AED where it is needed. Reading the two-dimensional code may also trigger the provision of an AED utilization status, a defibrillation intervention position, or a warning that other AEDs are being routed to that intervention position. intervention, etc.
