INTERVENTION REQUESTS

DESCRIPTION

Field of the invention

The present invention refers to an electronic system of and transmission of requests of intervention in rescue.

The present invention refers furthermore to a method of management and transmission of requests of intervention in rescue.

Background art

Many of the rescue interventions to injured persons have a positive result in accordance to the immediate rescue of the injured person, and more in general to the time lapsed between the accident and the first rescue intervention.

This concept is widely explained in a specific acceptation called "golden hour", that refers to the period of time that goes from some minutes to a many hours after the traumatic injury caused by an accident, during which there is the highest probability that an immediate medical treatment can avoid the death. In order to save human lives, the most immediate intervention on the injured person is therefore necessary.

Observing more in detail the time that lapses between the moment of the wounding (accident) and the take in charge of the injured patient by the hospital, it can be observed as the most critical time and anyway the time with less surveillance is given by those instants of time that separate the wounding from the intervention of a first responder.

Said first responder, that not necessarily is a medical practitioner, can be for example a volunteer with potential training for emergency resuscitation by means defibrillating devices (trained BLS responder). Typically the Applicant has observed that for what deals with the intervention of the first responder, most of the waiting time is - traditionally - due to the waiting time of a rescue vehicle as of an ambulance is an example.

Said waiting time, therefore, directly derives from the geographic proximity between a rescue vehicle and the injured person.

There are localization systems for rescue vehicles, that allow by means of the transceiving of radio signals between the rescue vehicle and an operations center, to know immediately the real position of rescue vehicles. Said system is commonly employed for selecting the vehicle which is closest to the injured person, and for manually alerting it - preferably but in a non-limiting extent by means of one selective radio call - thereby providing to the driver the most possible precise indication for the location of the injured person.

If the rescue vehicle is far, in contrast, traditionally the injured person requires more time for receiving the first BLS treatment. Said time can lead to an unfavorable exit solution for the injured person.

It is known as well that in densely populated areas, but not only, there is a great amount of qualified responders, volunteers or not, or doctors that could be readily alerted and rescue the injured person.

The scope of the present invention is therefore to describe an electronic system of management and transmission of requests of intervention in rescue, that allows for reducing the time of intervention of first rescue on an injured person, not only in accordance to the position of the rescue vehicles that are present on the territory in proximity of the injured person.

Summary of the invention

According to the present invention it is therefore realized an electronic system of management and transmission of requests of intervention in rescue, which allows to intervene on the injured person verifying, in the modalities better described hereinafter, when a qualified first responder can intervene on the injured person before the arrival of the rescue vehicle, and if, in affirmative case, can electronically alert said first responder to the end that the time necessary for letting the injured person receive a first rescue by the qualified personnel is reduced to the minimum possible.

In detail, according to the present invention is realized an electronic system of management and transmission of requests of intervention in rescue, said system comprising electronic means of reception of a rescue intervention request, wherein said rescue intervention request takes place by means of the transmission of a signal of rescue intervention request, an electronic computer comprising at least one memory in which is stored an intervention file, associated to said rescue intervention request, wherein in said memory is stored a plurality of telephone numbers or codification indexes univocally associated to a plurality of users previously selected as responders, said system comprising furthermore electronic means of transmission of alerting, configured for transmitting said rescue intervention request towards remote electronic devices associated to responders by means of an alerting signal, selecting at least one part of said telephone numbers or codification indexes, and for receiving one signal of acceptance of rescue intervention by one or more of said remote electronic devices, wherein said signal of intervention acceptance comprises one data of position of the remote electronic device by which said signal of intervention acceptance comes from, and intervention authorization confirmation means, electronically computing one first estimated trip time between a position of an user to be rescued and said position of said remote electronic device from which said signal of intervention acceptance comes.

According to a first aspect of the present invention, said system is characterized in that said intervention authorization confirmation means furthermore calculate a second estimated time for the intervention of a rescue vehicle receiving a datum relating to its position up to the position of said user to be rescued, and transmit to at least part of said remote electronic devices said second estimated time for the intervention of said rescue vehicle.

Furthermore, said intervention authorization confirmation means electronically calculate said first estimated trip time between said position of said user to be rescued and said position of said remote electronic device by which said signal of intervention acceptance comes.

According to a further aspect of the present invention said intervention authorization confirmation means are configured for sending one electronic signal of confirmation of rescue intervention in case said second estimated trip time exceeds with respect to said first estimated trip time.

In a further aspect of the present invention, said second estimated trip timeis computed according to an electronic estimation of the time necessary to said rescue vehicle to arrive to the position of said user to be rescued in accordance to cartographic data stored in advance and/or electronically calculated by said electronic computer.

Advantageously, in said memory are pre-emptively stored georeferenced positions of a plurality of rescue devices, and wherein said alerting signal, comprises data relating to said georeferenced positions of said plurality of rescue devices close to the zone wherein said user to be rescued is present. Advantageously, in said system there are means defining a maximum number of responders simultaneously confirming said signal of acceptance of a rescue intervention.

More in detail, said means are configured for transmitting one denial of rescue intervention to the remote electronic device of the responder which has sent said signal of acceptance of said rescue intervention when said maximum number of responders has been exceeded. In a preferred and non-limiting aspect of the present invention, said means are configured for transmitting one confirmation of rescue intervention towards the remote electronic device of the responder which has sent said signal of acceptance of said rescue intervention when said maximum number of responders has been exceeded if said position of said responder is closer to the position of said user to be rescued with respect to the position all the other users that have already transmitted said acceptance of said rescue intervention.

Alternatively or in combination, said means are configured for authorizing always the confirmation of rescue intervention towards the remote electronic device of the responder having sent said signal of acceptance of said rescue intervention when said maximum number to responders has been exceeded, if said position of said responder is below a predetermined distance with respect to the position of said user to be rescued.

According to the present invention it is further described a method of management and transmission of requests of intervention in rescue, said method being characterized in that it comprises:

- one step of receiving a rescue intervention request from electronic means of a system of management and transmission of requests of intervention of rescue, wherein in said step of receiving there is a transmission of a signal of rescue intervention request directed towards said system,

- step of storage of an intervention file, associated to said rescue intervention request, in a memory of an electronic computer,

- a preventive step of storage of a plurality of telephone numbers or codification indexes univocally associated to a plurality of users previously selected as responders

- one step of transmission of said rescue request by means of electronic means of transmission of alerting, and wherein said step of transmission of said rescue request comprises transmitting said rescue intervention request towards remote electronic devices associated to responders by means of an alerting singal, and comprises one step of electronic selection by said electronic computer of at least one part of said telephone numbers or codification indexes

- one step of receiving one signal of acceptance of rescue intervention by or more of said remote electronic devices, wherein said signal of intervention acceptance comprises one data of position of a remote electronic device by which said signal of intervention acceptance comes from,

- one step of electronic calculation, by intervention authorization confirmation means of said system, of a first estimated trip time between a position of an user to be rescued, and said position of said remote electronic device by which said signal of intervention acceptance comes.

In one aspect of the present invention, in said method said intervention authorization confirmation means perform a step of electronic calculation of said first estimated trip time between said position of said user to be rescued and said position of said remote electronic device by which said signal of intervention acceptance comes, and a step of electronic calculation of a second estimated trip time for the intervention of a rescue vehicle by an its predefined position with respect to the position of said user to be rescued.

In one further aspect of the present invention, said intervention authorization confirmation means performs a sending of a signal of confirmation of rescue intervention in case said second estimated trip time exceeds with respect to said first estimated trip time.

In detail, said second estimated trip time is computed on the basis of an electronic estimation of the time necessary to said rescue vehicle to arrive to the position of said user to be rescued in accordance to cartographic data in advance stored and/or electronically calculated by said electronic computer.

In said memory are pre-emptively stored georeferenced positions of a plurality of rescue devices, and wherein said signal of signal of rescue intervention request, comprises data relating to said georeferenced positions of said plurality of rescue devices close to the zone wherein said user to be rescued is present.

In one aspect of the present invention, said method comprises furthermore one step of preventive storage on said electronic computer or of electronic retrieval by said electronic computer of a plurality of data of position of a plurality of medical devices or rescue devices present on the territory, and wherein said step of transmission of said alerting signal comprises or is followed by a step of transmission of said data of position of said plurality of medical devices towards said remote electronic devices of said responders.

Advantageously, said method furthermore comprises a step of electronic navigation of a responder towards one of said medical devices or rescue devices present on the territory, said step of electronic navigation following a preventive step of electronic selection of one between said rescue devices present on said remote electronic device of said rescuer following said transmission of said data of position.

Advantageously, said method furthermore comprises a step of transmission of a rate of cardiac massage by a software application installed or anyway electronically run on said remote electronic device by means of visual and/or auditory means.

In the method according to the present invention, electronic means of transmission of alerting receive from the remote electronic devices of the responders a certain number of signals of acceptance of rescue intervention and in case said limit of acceptance is exceeded, no more accept signals of acceptance of rescue intervention from electronic devices of further responders.

In detail, when the limit or maximum number of signals of acceptance of rescue intervention received by the electronic means of transmission of alerting is exceeded: - if the new responder that sends one signal of acceptance of rescue intervention finds himself closer than other responders that already have confirmed their acceptance to the rescue intervention with respect to the position of the user to be rescued, to said new responder is confirmed the authorization to proceed with the rescue;

- if the new responder that sends one signal of acceptance of rescue intervention is in a position farther than at least one of the other responders that already have confirmed the their acceptance to the rescue intervention with respect to the position of the user to be rescued, to this new responder is denied the authorization to proceed with said rescue.

Detailed description of the invention Referring to the annexed figures, with the reference numeral 10 in its complex is shown an electronic system of management and transmission of requests of intervention in rescue.

The system 10 object of the present invention presents one electronic computer 120 that preferably but in a non-limiting extent is one personal computer and/or one system server, connected by means of known technique to electronic means of reception of a rescue intervention request 110, that in an exemplificative way, in figure 1 are represented by an antenna. Said representation shall not be intended in a limiting extent, since said electronic means of reception of a rescue intervention request 110 could also be or further comprise a modem connected in Internet or with a cellular telephone network. In this way said means can receive a rescue call for example by a cellular telephone or by an user close to a user to be rescued 400, or injured person.

The electronic computer 120 presents one memory 121 within the quale are stored at least:

- a plurality of telephone numbers or coding identifier of a plurality of responders 180, each one provided with one respective electronic device 171, 172.

Said electronic device for said responders 180 is alternatively and preferably a cellular telephone 171 or a radio or pager 172. In both the cases said electronic devices are characterized by a univocal identification number or code, precisely represented by said telephone number or indicator of selective call or other known system.

The responders 180, for the purposes of the present invention, are common people and not necessarily doctors or professionals engaged in rescue, that for any reason could be in proximity of the user to be rescued 400. The responders 180 are part of a plurality of people 150 already authorized or anyway allowed to perform first rescue, preferably but in a non-limiting extent BLS-type maneuvers, on a user to be rescued. The plurality of people 150 that is allowed or authorized to operate as a rescuer is stored in advance in the electronic computer 120.

The electronic computer 120 presents furthermore electronic means of transmission of alerting 160, preferably but in a non-limiting extent comprising a system of telephonic transmission for executing calls towards fixed and/or mobile telephone number and/or a radio system for sending radio signals towards said electronic devices. Both said telephonic and radio transceiving systems can advantageously be simultaneously present, in case in an integrated structure, and send and receive electronic signals of alerting from and towards the computer on the basis of a command of rescue intervention request that arrives thereto from said electronic computer 120 according to the operative features of the system object of the present invention that better will be described in the following part of the present description.

In detail, said electronic means of transmission of alerting 160 perform a sending of an alerting signal towards said remote electronic devices 171, 172 of the responders, preferably selecting at least one part of these last.

Preferably even though in a non-limiting extent, each rescuer 180 can configure his mobile phone 171 or radio or pager 172 in such a way that appropriate alerting signals like a sound or visual signal emitted by the cellular telephone 171 or radio or pager 172 can be heard only if the coordinates of intervention and in particular the position 300 of the user 400 to be rescued, transmitted as electronic data of position, lays within a predetermined radius with respect to the position of said cellular telephone 171 or radio or pager 172. Specifically, in this case, the cellular telephone 171 or the radio or pager 172 are provided with an own satellite receiver configured for allowing the positioning and, subsequently, the electronic comparison with respect to the position 300 of the user 400. The electronic means of transmission of alerting 160 receive from the remote electronic devices 171, 172 a returning signal that represents a signal of acceptance of rescue intervention 190.

In detail, the signal of acceptance of rescue intervention 190 is transmitted when the remote electronic device 171, 172 of the responder 180 can be reached; this means that if for example a responder 180 has the cellphone switched off or has the radio or pager out of range, said signal of acceptance of rescue intervention 190 is not transmitted.

The signal of intervention acceptance which is transmitted by the remote electronic devices 171, 172 comprises preferably but in a non-limiting extent a data of position of the remote electronic device from which it comes from. This means that the remote electronic device 171, 172 shall have means of positioning - preferably electronic - which for example and in a non-limiting extent a GPS or similar global positioning system, or yet have user interface means from which it can retrieve a data of position introduced in input by a user and retransmit said datum together with a signal of intervention acceptance of rescue 190.

Therefore, at the moment it receives the signal of acceptance of rescue intervention 190 the electronic computer 120 receives a preventive confirmation of availability of one or more responders 180 in advance stored and a position thereof.

Inside the electronic computer 120, intervention authorization confirmation means 200, realized by means of a separate electronic unit or as a software algorithm operating within said electronic computer, calculate an estimated interval of time that represents a first estimated travel time 210 between a position 300 of the user to be rescued 400 and the position of said remote electronic device 171, 172 that has already transmitted the signal of acceptance of rescue intervention 190. Figure 2 visually shows a case wherein a responder 180 provided with an own radio 172 is in a predetermined position in an urban environment, cartographically represented on a monitor of an operations center of management of rescue to which the system object of the present invention refers to. The first estimated time 210 is the time t ₂ (thick dashed line).

The position 300 of the user to be rescued 400 can be preferably electronically calculated starting from the incoming call with the rescue intervention request, or less preferably but still possibly be received via voice by who calls the rescue structure.

In one preferred and non-limiting embodiment of the present invention, the electronic computer 120 further calculates second estimated time 220 for the intervention of a rescue vehicle 500 from a predefined position thereof up to the position 300 of the user to be rescued 400. Always referring to figure 2, the second estimated time is indicated with ti (thinner dashed line).

For the purposes of the present invention, as rescue vehicle shall be intended a vehicle provided with medical devices and/or doctors or paramedics on board, preferably provided with visual or acoustic/visual signaling means, suitable for loading the injured person on board for transporting him to an hospital. For the purposes of the present invention said rescue vehicle can be a road vehicle, like an ambulance, or an air rescue vehicle, like a helicopter aeroambulance or still be a boat and/or an off-road vehicle.

When said calculation of the second estimated time 220 is performed, immediately the electronic computer 120 calculates a difference between the first and the second estimated time 210, 220.

When the first estimated time 210 is lower than the second estimated time 220, this means that the responder 180 can reach the user to be rescued 400 before the arrival of the rescue vehicle 500. When the second estimated time 220 is lower than the first estimated time 21, this means that the responder 180 cannot reach the user to be rescued 400 in a time lower than the time necessary for the arrival of the rescue vehicle 500; this last arrives quicker.

Advantageously this electronically calculated difference allows for confirming the intervention only in case the responders 180 can actually arrive before the rescue vehicle, and therefore represents an important management of the rescue resources that are present in the area.

Alternatively, independently of the difference between the first and the second estimated time 210, 220, the responder 180 can in any case receive confirmation of the access to the intervention also in case the time he needs to arrive on the position 300 of the user to be rescued is higher than the time necessary for the vehicle 500 for coming on the position 300 itself.

The rescue vehicles 500 are typically provided with global positioning means that allow to operations centers to learn their real-time position.

When the second estimated time 220 is calculated, through the electronic means of transmission of alerting 160 is also sent a signal of request of position towards the rescue vehicles 500 in case present in the territory, which respond to the request of transmission of a signal of position that is then represented in the operation center on user interface means of a known type, preferably but in a non-limiting extent comprising a monitor, in a cartographic form.

On the basis of a pre-existing cartography and anyway electronically stored and electronically retrieved by the electronic computer 120, in the system object of the present invention is calculated electronically which is the time necessary to the rescue vehicle 500 for coming to the position 300 of the user to be rescued 400 according to the roads actually present.

Preferably, also the first estimated time 210 is calculated in the same way. This advantageously allows having an estimation of the intervention times respectively of the responders 180 and of the rescue vehicle 500 very precise, since it would be wrong supposing that both can "jump" buildings or pass straight through them joining the point of their position with the point of the user to be rescued 400.

In one preferred and non-limiting embodiment of the system 10 object of the present invention, in the electronic computer 120 are optionally stored also georeferenced positions 820 on the territory of a plurality of rescue devices 821 (for example and in a non-limiting extent, automatic defibrillators of anyway kits of advanced sanitary intervention) that advantageously allow to the rescuer 180 to intervene on the patient far more effectively. In said case, during the transmission of the alerting signal, said signal comprises the transmission also of said georeferenced positions 820 of the plurality of rescue devices close to the zone wherein the user to be rescued 400 is present.

In detail said rescue device 821, symbolically represented in figure 2 by the acronym AED (Automated External Defibrillator) can either be on the path travelled by the responder 180 for coming on the user 400 to be rescued, as in case of figure 2, or farther or beyond with respect to the position of the user 400 to be rescued. It is not important if also this condition takes place, since in any case the responder 180 is advantageously guided or anyway electronically instructed through the transmission towards its electronic device of with a specific signal both towards the position of the user 400 to be rescued and towards the position of said rescue device 821.

To this regards, therefore, before transmitting the alerting signal, the electronic computer 120 first recalls from the memory the positions of said rescue devices 821, then compares electronically their positions with that of the user to be rescued 400 and then, on the basis of a radius that was previously defined and store, electronically calculates if the positions of said rescue devices 821 lay within a predefined radius from the position of the user to be rescued 400 and in affirmative case, provides for sending the data relating to these last positions to the alerting signal.

In other words, through the system object of the present invention data coming from three floors or "layers" are combined and calculated in real time, these layers are electronic layers of position:

- a first layer representing a map of the area wherein there is the user 400 to be rescued and representing a plurality of positions of rescue devices 821 to which the responders 180 can refer to in order to optimize the procedure of resuscitation on the user 400,

- a second layer representing the position of the responders 180; and

- a third layer representing the position of the rescue vehicle 500.

Specifically, while the first layer represents time-invariant data, since the position of the user to be rescued 400 and of the rescue devices 821 is defined and fixed when the intervention is considered, the second and third layer manage electronic layers of positioning whose data are time-variant.

Figure 3 shows a schematic diagram of the times during a request of intervention towards a user to be rescued 400. Following a call that represents the signal of rescue intervention request 125, that is received by the service of medical emergency the electronic computer 120 receives a signal of request of opening of an intervention file 123 and sends to a plurality of users or responders 180 an alerting signal 181 to which some responders whose electronic device 171, 172 is active or reachable, sends one signal of acceptance of intervention 190. Together with said signal are also sent coordinates of the position 310 of the responder 180.

Then, according to the fact that the first estimated time is lower than the second estimated time (t2<tl) or vice versa (t2<tl),

- if the first estimated time 210 is lower than the second estimated time, a signal of confirmation of authorization to the intervention 200 is sent towards the electronic device of the selected responder user 180, and an electronic real time tracking 900 thereof is followed. Said tracking takes place by means of continuous and/or repeated transmission of data of position of said electronic device 171, 172 of said user towards the electronic computer 120.

If the first estimated time 210 is greater than the second estimated time, to the electronic device 171, 172 associated to said responder 180 is sent a signal of denial of authorization to the intervention 201.

Figures 4 and 5 show respective schemes of commands in the management of the system object of the present invention.

In the system object of the present invention there is a plurality of functional elements which are one external system 1000, an API 1001 and one mission control 1002.

At the moment of creation of the mission request 1003, transmitted by the external system 1000 to the API 1001, a mission file 123 is created and is requested to the API towards the mission control 1002 an input of a mission 1004. Immediately after, the API 1001 transmits towards the external system the creation of a response 1005.

By the external system 1000 there are requests of update (update) of the mission request 1006 that come to the API 1001 and are then transmitted with a mission update 1008 towards the mission control 1002.

In case the external system 1000 requires an information on the rescue mission, this system generates a signal of request of information on the mission 1009 and transmits it towards the API 1001 which retransmits it (arrow 1010 in figure 4) to the mission control 1002.

Here the API itself transmits the information on the required mission 1011 towards the external system 1000.

Preferably, but in a non-limiting extent, the mission information comprises the following fields: - univocal identification code of the mission;

- name;

- telephone number and coordinates of the responder 180.

The external system 1000 can further send a cancel of the mission request 1012 towards the API 1001, which performs the sending of a command of update of the status of the mission 1014 transmitted towards the mission control 1002. The API itself sends then towards the external system 1000 a deletion of the response 1013.

As further illustrated in figure 4, the system object of the present invention further comprises an event broker 1032 that in turn interfaces with a publication interface 1030 (publisher) and a subscription interface 1031. In turn, the event broker communicates in cascade with an event topic.

Operatively, the publication interface 1030 can send a command of register 1015 towards the event broker 1032, which performs an add publisher 1016 command following which the publication interface 1030 sends a command of publication 1017 towards the event broker. This last at this moment sends a command of creation (create) 1018 towards the event topic.

The external system that represents the subscriber 1031 then sends to the event broker 1032 a command of registration 1019 following which this last performs an action of addition of a subscriber 1020. Then, the external system that represents the subscriber 1031 transmits towards the event broker 1032 a request of registration for the event that brings a parameter containing at least the name of the event itself. The event broker 1032 transmits towards the event topic an addHandler 1022 command.

By the publication interface 1030 a plurality of commands of cancellation of the intervention 1023 (Fireevent) can depart directly towards the event broker 1032 starting from which a GetHandlers 1024 command is sent towards the event topic. The event broker 1032 then sends a call subscriber 1025 request towards the external system.

In particular, in case the user of the system object of the present invention communicated with a remote electronic device 172 in the form of a cellular telephone, it its possible to use on said device a software application that allows the automatic login of the responder 180 on the system object of the present invention so that allowing to have the possibility of a prompt receipt of the alerting signal.

Through the software application it is possible to access the map stored anyway retrieved on the electronic computer 120, for visualizing the list of the rescue devices in proximity of the responder itself. Therefore the software application provides for visualizing on the screen of the electronic device 172 provided to the rescuer a map from which he can retrieve both its own position 310 as well as the position of the rescue devices, thereby having the possibility of rapidly visualizing the best strategy for performing the rescue.

Furthermore, on the map he can also interact, through for example the touch of the position corresponding to the identified rescue device; with said interaction can be obtained a request of transmission of data concerning said rescue device towards the electronic computer 120, which responds transmitting towards the requesting electronic device said data that preferably but in a non-limiting extent comprising for example an image of said rescue device.

The software application further advantageously comprises also a function of navigation, that if activated by a rescuer 180, guides this last towards the position of the predefined rescue device. Said function of the application software is totally autonomously and independently from the system 10.

A further function of the application software object of the present invention consists furthermore in the possibility of managing a function of rate of cardiac massage. Through this function, the software application causes the emission of a sound signal at the rate which is necessary for performing a cardiac massage. In this way, it is possible to obtain a greater efficiency in the cardiac massage itself, since this is performed with an audible guidance at the right rate, and it is avoided that the responder, for any reason, can depart from the most appropriate massage rate. The rate imposed by means of the audible signal can be further imposed by means of visual signaling means, which for example a flashing of the screen of the electronic device provided to the rescuer.

Specifically, the software application object of the present invention, when receives said alerting signal, makes the electronic device emit an audible signal. The responding user 180 then provides for accessing to an "Emergency" section of said software application wherein there are one or more active emergencies. The responder 180 selects one of said emergencies and the software application causes the opening of a visualization with minimal details concerning the intervention. The confirmation of the availability of the responder 180 takes place by means of a command which is transmitted by said responder specifically through the application and only when the timings of intervention are verified as above described, then the system object of the present invention transmits towards the electronic device of the responder 180 the complete data of the intervention.

In one further embodiment, the system 10 object of the present invention is configured for allowing the communication between an operations center and the responder 180. Technically this is realized by selecting one of the remote electronic devices 171, 172 of one of the responders 180 directly through the electronic computer 120, and sending to this last alternatively:

- a command of request of opening of a session of telephonic communication (incoming call towards the remote electronic device 171, that as said is a cellular phone) or VoIP according to a known technique; - a sending of a radio signal of request of selective calling towards the remote electronic device 172, that as said is a radio or a pager.

The creation of a call between the central and the responder allows this last to have clearer indications on the rescue to be performed, and in case interact with people present in the operations center in case the rescue presents any issues not foreseen in advance.

The applicant considers that the instauration of a call between the central and the responder can take place in any operative phase of the system 10 object of the present invention, and therefore not only after the sending of the alerting singal 160 or of the signal of acceptance of the rescue intervention 190, but also before the electronic sending of said signals.

With the instauration of the call, a video data flow can be optionally transmitted by a remote electronic device 171, 172 towards the computer 120. This transmission of the video data flow takes place according to a known technique, and advantageously allows to acquire more conscience of the situation of intervention to the persons in the operations center wherein there is the electronic computer 120 or that anyway operates through it.

Furthermore the system object of the present invention can be further integrated with external systems, expanding operativity and applications thereof.

The applicant has finally found that in the procedure of acceptance of the calls of responders 180 or first responders it is possible to have a limit of acceptance per category or not.

In case there is a limit of acceptance per category, the electronic means of transmission of alerting 160 receive from the remote electronic devices 171, 172 of the responders a certain number of signals of acceptance of rescue intervention 190 and in case said limit of acceptance is exceeded, do not accept more new signals of acceptance of rescue intervention 190 by electronic devices of further responders. This has from one side brings to more efficiency in the management of the rescue intervention, since it limits the number of people that can be alerted, containing the employment of human resources and then costs.

Anyway the use of a limit to the number of acceptances of the rescue intervention 190 for an "hard" type, as it is the one described, do not keep into account the proximity of new responders 180 that could be closer than those that have already confirmed the acceptance of the rescue intervention, but that have simply - for any reason - took more time to respond to said rescue request.

In any case, the use of a limit of acceptances of rescue intervention 190 of a "hard" type causes an inefficiency in the management of the rescue itself. In other words, using a "hard" limit imposes a careful selection of the number of responders that can be authorized, and often said number shall be manually adapted or varied from time to time in accordance to the type of requested intervention.

The applicant has found therefore the need of creating a soft-type algorithm of rescue, which allows to overcome the overall efficiency of the "hard"-type algorithm.

In a "soft"-type algorithm:

- the electronic computer 120 always contain stored a maximum number of signals of acceptance of rescue intervention 190 by respective responders;

- when the limit or maximum number of signals of acceptance of rescue intervention 190 received by the electronic means of transmission of alerting 160 is exceeded:

- if the new responder 180 that sends a signal of acceptance of rescue intervention 190 is closer than other responders 180 that already have confirmed the their acceptance to the rescue intervention 190 with respect to the position 300 of the user to be rescued 400, to this new responder is confirmed the authorization to proceed with the rescue; - if the new responder 180 that sends one signal of acceptance of rescue intervention 190 is in a position farther than at least one of the other responders 180 that already have confirmed the their acceptance to the rescue intervention 190 with respect to the position of the user to be rescued 400, to this new responder the authorization to proceed with said rescue is denied.

In one preferred embodiment, furthermore, the algorithm of acceptance and confirmation of the rescue intervention towards the responders, is configured so that the electronic means of transmission of alerting 160, when they receive a signal of acceptance of rescue intervention 190 from a responder, also beyond the numeric limit imposed before, and when said responder 190, following the calculation as before described shows that he is at a distance closer than 500m with respect to the position 300 of the user to be rescued 400, said responder 190 is in any case authorized to proceed with the rescue and therefore can be electronically authorized to proceed with the intervention as described above.

Said feature advantageously allows of having a sort of bypass that always allows the quickest possible intervention on the patient.

A further development of the present algorithm up to here described, consists in verifying, following the acceptance of the rescue intervention 190, by means of the tracking 900, the actual approximation of the responder to the position 300 of the user to be rescued 400. In case the responder 180 does not get in average closer to the position of the user to be rescued 400, said responder 180 is excluded by the list of the actually operative responders. This implies that at electronic computer 120 level, the number of the responders that have confirmed the acceptance of the rescue intervention 190 is decremented of a unit, leaving therefore the operative place for a new responder 180 whose distance with respect to the position 300 of the user to be rescued 400 would also be greater than that of the other responders. Optionally, the remote electronic device 171 can integrate a software application for communicating with a watch provided with a display on which operative parameters of the rescue mission and/or of the status of the request and acceptance of intervention itself can be verified.

Said software application, preferably but in a non-limiting extent comprises means for allowing a visualization of the list of the missions, for example under the form of a tab, the result of the acceptance of the rescue intervention request 190, information about the active mission and mission details, eventual electronic buttons for requesting the call of an emergency number (es. 144 or 1414 Rega), the list of defibrillator devices closer to the calculated position of said remote electronic device 171, the detail of the DAE and a sound of an heartbeat for helping the responder calculate the cardiac frequency of the injured person once reached.

The applicant notices that through the opening of a radio or VoIP channel suitable to make an audio data stream flow between the remote electronic device 171, 172 and the electronic computer 120, it is therefore possible to transmit sounds concerning heartbeats of the users 400 to be rescued, that can be directly calculated by the electronic computer 120 preferably together with an electrocardiographic track that is optionally transmitted as an electronic datum together or in alternative by the remote electronic device 171, 172 towards said electronic computer 120. The electronic computer 120 has a calculation capacity such that to perform for example a filtering of an electrical noise of the electrocardiographic track and for sending it or letting it be visualized by a doctor in real time.

Optionally, the system object of the present invention can be rendered interactive with interactive glasses like Google Glass, in such a way to allow a more favorable transmission of the operative scenario. Furthermore, through the software application which is optionally installed on the remote electronic device 171 when it being a cellular phone, it is possible to transmit towards the electronic computer 120 also documents which are inherent to the rescue and a feedback of the end of the call by the responder.

The integration with external devices of the system like for example the DriveOnStreet application, allows to verify also the type of the locomotion means on which the responder moves.

The electronic computer 120 can also be optionally configured for managing a plurality of operative intervention scenarios by responders, therefore for example subdividing more responders 180 in separated groups, operating on a same of different interventions, eventually integrating a map of tracking of the various responders in real time.

Finally, in one further preferred and non-limiting embodiment of the present invention, the system comprises means of alerting and preferably automated guidance of drones.

In detail, when the position 300 of the user to be rescued 400 is established, a procedure of automatic starting of the drone is activated, from the starting place up to said position 300, following a predefined path or that can be adapted from time to time to operative situations and scenarios. The drone is equipped with a cardiac resus device like a defibrillator.

The applicant considers that the automatic starting of the drone represents an undoubtful operative advantage in particular when the accident takes place in areas wherein the sanitary resources of first care are both far away from the rescuer or the closer responders which have been alerted, and from the user to be rescued 400 itself.

The advantages of the system object of the present invention are clear in the light of the description that precedes. In detail through the system 10 object of the present invention it is possible to reduce the time which is needed in order to intervene on an injured person, since responders potentially present in the area can reach injured person to rescue him before the arrival of the rescue vehicle.

Nonetheless, through the system object of the present invention the rescue takes place in an efficient way, that is the actual engagement of personnel for rescue happens only when they - by means of electronic calculations - can actually intervene before a rescue vehicle. Therefore advantageously through the system object of the present invention the engagement of rescue personnel - especially when volunteering - is not blindly realized, but with a preventive calculation of the actual time of arrival on the injured person. Therefore, the resources of rescue personnel can advantageously be optimized.

Furthermore, through the system object of the present invention is possible monitor in real time not only the position of the rescue vehicles but also the rescue personnel itself, and also to keep advantageously statistic trace of the interventions which have been performed during the time.

Indirectly, through the system object of the present invention it is therefore possible to monitor, according to the reciprocal position between the injured person, the rescue vehicles and the rescue team, which actually are the most favourable routes to follow in case of rescue intervention.

It is finally clear that to the object of the present invention can be applied additions, modifications or variants, which are obvious for a technician skilled in the art without for this departing from the scope of protection provided by the annexed claims.
