Description

“Mobile application for first aid maneuvers”

Description Field of the invention.

The present invention operates in the field of first aid health care. In particular, the proposed invention relates to a software application for mobile devices that allows to practice major first aid maneuvers and to guide the user step by step in the execution of said maneuvers in cases of real emergency.

Prior art

In the current state of the art, a great number of mobile applications for smartphones and tablets are available that offer multimedia contents (videos, slideshows, interactive documents) directed at learning or reviewing first aid procedures such as cardiopulmonary resuscitation and airway obstruction removal maneuvers. At the same time, with advances in technology and the possibility of miniaturizing electrical circuitry and electronic components, a whole series of devices has become widely used for facilitating the practical teaching of first aid maneuvers both to personnel working in the sector, and to ordinary persons. Familiarization with these emergency procedures, by non-specialized personnel, would represent an enormous advantage in case of a health and medical emergency, because it would considerably increase the probabilities, for the person in need, of receiving first aid while awaiting the arrival of medical personnel. It appears clear that the higher these probabilities the more persons are able to perform first aid maneuvers. In this context, the very widespread use of cellular phones and movable devices in general offers the - unprecedented - opportunity to reach a very high number of individuals and to provided audiovisual contents that reproduce on the screen the main life-saving medical procedures as a guide. As specified above, very many applications for mobile devices are available that allow to view step-by-step guides for the execution of first aid maneuvers, however recent studies confirm that the occurrence of administration of first aid by onlookers in case of emergency remains low, in spite of the very ample availability of information material. The main reason for this infrequency, according to the same studies, is the lack of practicality: in the vast majority of the cases, cardiopulmonary compression and airway obstruction removal maneuvers are taught with lectures or practical demonstrations by specialized personnel. In both cases, without specific preparation, the necessary actual practice of the procedures is insufficient or absent altogether.

On the other hand, specific teaching devices, designed to serve as aids for practical learning, are not commonly available to everyone, are often difficult to handle and uneconomical; lastly, to be effectively used, they need particular supports, capabilities and knowledge of the sector. The potential of the hardware of the mobile devices, which nowadays are provided with advanced sensors and geolocalization capabilities as well as access to high performance data networks, is not fully exploited.

An additional deficiency, in the examined field, is the unavailability of a functionality that allows not only to facilitate the execution of first aid maneuvers, but also to provide assistance in real time, to contact paramedic personnel rapidly while providing a general description of the situation, including the exact position, and showing the conditions of the ill person, taking into account any language barriers.

Although a plurality of patents pertaining to this subject are available internationally, for example the United States patent US2017172844A1 which proposes an automatic system for a device for determining the correctness of the cardiopulmonary resuscitation or patent WO2017175922A1 that relates to a method for training of first aid maneuvers by means of a manikin and an electronic device, it is clear that neither of them exhaustively addresses the illustrated problems.

Description of the invention

According to the present invention, a mobile application (app) is realized that effectively solves the problems described above, allowing to use common portable electronic devices such as smartphones, tablets, PDA or smart watches, to learn, exercise and be guided in the execution of some basic first aid maneuvers. The application exploits the potential of the hardware of the mobile devices in order to use them as teaching aids available to everyone: in particular, it proposes to use the accelerometer sensor to measure and record the movements carried out by the user during the execution of the maneuvers. The software allows to perform practice sessions on first aid maneuvers using household objects as if they were common training manikins, currently used during first aid courses, and to receive negative or positive feedback on the correct execution of the aforesaid maneuvers, assisting the user as a“virtual instructor” during the practice sessions.

Also provided is an emergency utilization mode that assists the user in providing first aid, administering audiovisual contents and putting him/her in touch with the local medical units. The software will advantageously be cross-platform, downloadable and installable on the most widely used mobile devices and compatible with different operating systems, such as Android, IOS, Windows Mobile, tec. In addition, a proprietary, customized realization is provided on hardware designed ad hoc , dedicated exclusively to the utilization of the application. The user interface is conceived to be simple to use and to stress immediacy and accessibility.

The choice to use mobile devices, which are small sized and lightweight, entails the advantage of being able to use the application anywhere and it is an essential requirement for the emergency operation mode. Moreover, the application, to the widespread use of cell phones and, lately, of smart watches makes it possible always to have available a first aid instrument that increases the probabilities of intervening rapidly and, in many cases, to contribute to save human lives. To maximize mobile utilization, the application will be developed in such a way as to be able to continue to operate - albeit in a limited manner - even in the absence of connection to the data network: the multimedia contents that guide the learning and execution of the maneuver will be permanently stored in the internal memory. In the presence of a connection to the data network (both through telephone operator, and by means of WiFi), the application will offer full functionality, taking advantage of the availability of continuous updates, video-call capability and access to online services.

The application is advantageously organized in two parts: a practice mode and an emergency mode (selectable from a menu); in the most common implementation, there are two first aid maneuvers: the Heimlich maneuver (airway obstruction removal) and cardiac massage. However, it is possible to instruct the software to include additional life-saving procedures or variations of the present procedures. The graphic interface will allow selecting the maneuver to be executed on a case by case basis.

In the practice mode, the app advantageously uses an innovative algorithm that exploits the accelerometer sensor of the mobile device to detect the movements of the user. The detected movements are subsequently stored in the form of a time track and compared with a standard model using correlation and proximity functions in order to determine the correctness of the maneuver being performed. Through a guided procedure, with audiovisual illustrative sequences and sound signals, the application will show the user how to perform each procedure, using the desired level of detail. Advantageously, a special training mode defined “virtual coaching” will be available, in which a virtual assistant will dictate to the user each step to carry out, verifying its correctness in real time. Both practice sessions require the user to utilize either a specific support (for example an anatomical manikin) or, in the most common case, they suggest easily found objects such as a pillow (anti-suffocation maneuver) or a mattress (for cardiopulmonary resuscitation). Before performing the maneuver, the application will show an illustrative video with the purpose of referencing the essential steps. At the end of the video sequence, the practice session starts, with help screens that guide the user in the various steps and in the correct positioning of the hands and of the body.

In the Heimlich maneuver, the application will suggest - in the absence of a manikin - using a pillow. After the illustrative video is played, the following steps will be carried out:

- the user, after having a pillow adhere to his/her chest, so that the upper base is at the same height as the base of the neck, brings the dominant hand, closed in a fist, to the center of the pillow;

if the application is installed on a mobile device of the smartphone or tablet type, with the contralateral hand the user lays it in horizontal position on the free base of the dominant hand;

if the application is installed on a smart watch worn on one of the two wrists, the user winds the fist of the dominant hand with the palm of the contralateral hand;

- the user then pushes the fist of the dominant hand into the pillow proceeding in anteroposterior direction and, rotating simultaneously the wrist in caudocranial direction, the device - laid down between the contralateral hand and the fist or fastened to the wrist - will follow the entire movement, measuring its characteristics;

- the measurements will then be compared with a reference model to verify the correct execution of the maneuver;

- the correctness of the movement will be indicated by sound signals or flashing of the screen.

In the cardiac massage procedure, in the absence of a manikin, use of a mattress or of a similar flat structure will appropriately be suggested. In this case, too, as soon as the user starts the practice session, an illustrative video will be played, at the end of which:

- the user places the dominant hand on the mattress, without exerting pressure thereon;

- the user lays the smartphone down in horizontal position on the back of the dominant hand and with the contralateral hand (s)he locks the smartphone on the dominant hand;

if the application is installed on a smart watch worn on one of the two wrists, the user sets the fist of the contralateral hand down on the back of the dominant hand, crossing his/her fingers;

- the user will be invited to perform the movements downwards, creating lunges into the mattress;

- the software of the application verifies the conformity of the movements performed with the reference model - stressing their correctness with sound and light signals - and will indicate the positive or negative outcome of the practice session.

Lastly, the application allows to keep a virtual diary of the practice sessions. The measurements of the accelerometers will be stored in an internal database on the device, supplemented with geotemporal information, outcome and score and any comments by the user. It will be possible, advantageously, to share the entries of the diary with other users on the Internet, using the most common social networks to raise users’ interest and to provide additional encouragement to practice daily.

In the emergency mode, the device - smartphone, tablet, PDA or smart watch - is not used as an instrument for the maneuver, but solely as a visual and audio aid. For each maneuver available in the software, at the time the emergency mode is initiated, the screen will be divided in two parts: in the top part, a sequence of images (slide show) will be reproduced, while the bottom part will be dedicated exclusively to the commands to manage the emergency. The sequence of images will advantageously be enunciated by audio messages reproduced at the highest output volume of the speakers. The idea is to be able to lay the device down in a suitable place to carry out the maneuver, with the aid of the messages of the application, even when unable to look at the screen.

In the case of the anti-suffocation maneuver:

- the display will show the maneuver, performed by an experienced rescuer, in the top part;

- the sequence of images will be repeated cyclically until the user’s manual intervention;

- the bottom part of the screen will show an“emergency call” push button; when it is activated, the application will autonomously contact emergency services, requesting their intervention and, if the device is provided with voice call capabilities, initiating a voice call;

on devices provided with data connection and suitable hardware, the activation of the “emergency call” push button will give rise to a video call with a healthcare worker. In the case of the CPR (Cardiopulmonary Resuscitation) maneuver, the application will show a very similar screen:

in the top part, a sequence of images, accompanied by audio messages, will illustrate to the user the correct step by step procedure;

- the sequence will be repeated following the intrinsically cyclical nature of the maneuver, with alternation of compressions and mouth-to-mouth breathing;

- the bottom part of the screen will show an“emergency call” push button with identical purposes and functionalities to those described in relation to the anti- suffocation maneuver;

- there will also be a second push button called“massage rhythm”, which will activate the voice guide to the maneuver. The guide will mark the rhythm of the compression with a sound signal and it will advise of the need to alternate thoracic compressions with mouth to mouth breathing.

The“emergency call” push button will always be present, regardless of the type of maneuver selected, and it may automatically send the GPS position to emergency services. To speed up alerting the emergency services, the application will keep - in an internal database - a list of the emergency numbers sorted by priority and divided by Country/Geographic Area. Therefore, the software will be able to association the position to a certain subset of emergency numbers and may make repeated calls, scrolling through all available numbers, until finding an available operator. An additional functionality that can be activated, after setting up the emergency call, is a simultaneous translation service that will make communication easier, advantageously allowing the user to rapidly convey all necessary information, without incurring the risk of running into the obstacles of language barriers. The simultaneous translation service will be available with online functionality for devices provided with connection to the mobile network.

The application, designed specifically for mobile use, may be installed on any portable electronic device provided with suitable operating system, computing power and memory. However, the following will be essential:

a sufficiently large screen, or with sufficiently high resolution, for the reproduction of multimedia contents;

a system of speakers and microphone; connectivity to the mobile network (direct or through associated device, as in the case of smart watches);

accelerometer sensor;

Dimensions and weight will be no higher than those of a common cell phone or tablet. Optionally, the application of the user may have access to additional functionality using a device provided with:

- touch screen;

connectivity to the mobile data network and WiFi;

- Bluetooth connectivity;

photo camera;

high-intensity LED;

additional internal or external memory.

Advantageously, a possible embodiment will be provided with dedicated customized mobile device, provided with all suitable functionalities and hardware characteristics for utilization of the application at its maximum potential. Said device will also have functional ergonomic characteristics for the purposes of the app, for example allowing its correct grip during practice sessions.

Lastly, an appropriate tool is advantageously provided for loading and developing models of maneuvers to be inserted in the library of first aid maneuvers of the application. The tool will allow to download on the device first aid procedures, additional multimedia contents and updates to the stored procedures based on the most recent health and medical prescriptions. The development of maneuver models takes place through the activation of a“recording” mode, through which an expert will be able to perform the maneuver using the device, allowing the software to memorize its movements with an accelerometer. The track thus obtained will then be cataloged as a reference model for the new maneuver and used - in practice session mode - to train the user.

The advantages offered by the present invention are readily apparent in light of the description provided hitherto and they will be still clearer thanks to the accompanying figures and the related detailed description.

When the practice session is activated, the screen relating to the maneuver 130 is shown with the illustrative video 131 and the time track of the values produced by the accelerometer 132. For the emergency model, the screen of the cardiac massage 150 is shown with the top area dedicated to the slide show 151, as well as the push button that activates the marking of the rhythm 152 and the push button that activates the emergency call 153. For the anti -suffocation maneuver 160, only the slides 151 and the emergency push button 153 are present. Detailed description of the invention

The present invention will now be illustrated purely by way of non-limiting or binding example, referring to the figures which illustrate some embodiment in relation to the present inventive concept.

With reference to FIG. 1, a possible configuration is presented of the mobile application 100 for practicing with first aid maneuvers that uses a common smartphone 200 as a mobile device. The device will have to possess determined features, including a sufficient operating system, computation power and internal memory to run the application 100. Also included will be a series of components and sensors necessary for the implementation of all functionalities provided by the application, and listed below:

- an accelerometer sensor, essential for sensing the movements made by the user;

a touch screen display 201 that will allow the user’s interaction with the interface of the application software;

a system of speakers 203 and microphone 206, which may give rise to hands-off communications;

- connectivity to the mobile phone network (TACS/GSM/UMTS/LTE);

connectivity to the mobile data network and WiFi;

a high resolution front photo camera 205 for making video calls;

GPS antenna 204 for user georeferencing; a high-intensity LED 202 to be used for light signals, such as the rhythm of thoracic compressions in cardiac massage;

internal storage device (SD Card).

The configuration described above will allow the application 100 to operate both in online mode, and in offline mode. Connection with the data network will allow updates to the contents, which will be permanently stored on the device, so as to be usable in the absence of a signal.

The application 100 is divided in two macro-areas:

a practice mode, which exploits the accelerometer of the device 200 and the stored video sequences to guide the user in the execution of first aid maneuvers;

an emergency mode that assists the user showing on the screen 201 the correct procedure to be followed by sequences of images, sound and light indications.

With reference to FIGS. 2, 3 and 4, the practice operating mode will be detailed below. Said mode is based on an innovative system for sensing the movements made by the user by means of the accelerometer of the device, storing them and obtaining therefrom a time pattern that will be available for comparison with a reference model 501. The reference model - pre-loaded in the memory - is in turn obtained recording the movements made according to best practices by a specialist in the first aid maneuver. The flow chart 500 of the basic algorithm is shown in FIG. 4.

Once the practice mode is selected, through the graphic interface, the system will allow the selection of the maneuver to be performed: Heimlich maneuver (anti-suffocation) or cardiopulmonary resuscitation. For each maneuver, the following are present in the system: illustrative multimedia contents, video guides and the possibility to display the outcome of the practice session. The actual practice session starts at the end of the video sequence. In the case of the Heimlich maneuver:

- the application will suggest using a pillow 312 in the absence of a manikin;

- the correct position to be taken for each maneuver will be displayed, in front view 310 and side view 311, with the position of the smartphone 200 clearly indicated; - the correct positions of the hands and of the mobile device are shown in detail, enunciated by a guiding voice-over;

- the user will be invited to position the closed dominant hand at the center of the pillow 313;

- the user will be invited to position the mobile device horizontally on the dominant hand 314;

- the maneuver 315 will be started, plunging the dominant hand into the pillow;

concurrently, the application will sense and record the movements using the signals coming from the accelerometer;

- at the end of the practice session, the application will compare the time track of the recorded signals with the reference model, providing a score and an outcome.

In the practice session on the cardiac massage, the request will similarly be made to use an anatomical manikin or, in its absence, a suitable support such as a mattress 321 or similar structure. Once the practice session is started and the demonstration video is completed, the application will:

display a sequence of images starting from the correct position which the user will have to assume 320;

show the position of the dominant hand on the support 322;

highlight the correct positioning of the smart phone 200 on the back of the dominant hand 323 for the reading to be valid;

show how to lock the dominant hand with the contralateral hand 324 and the resulting position of the mobile device;

give the signal for the maneuver to start, showing how to execute the plunges 325 on the mattress 321;

- mark the timing of the compressions with sound signals and guiding voice-over, while sensing and recording the movements made by the user.

At the end of the procedure, the movements made by the user will be compared with the pre- loaded model and an outcome and a score will follow. In both cases (Heimlich maneuver and cardiopulmonary resuscitation), the application may recommend repeating the maneuver in case of insufficient score, highlighting the mistakes made.

In the emergency procedure, the smart phone 200 is used as an audiovisual aid and as an instrument for rapidly alerting rescue services for each of the maneuvers present. The mode can be activated with a dedicated button of the main menu and allows to select the maneuver to be executed. The screen will then be divided in two parts: a top part dedicated to the illustrations pertaining to the selected maneuver; a bottom part dedicated to the interface of the controls, specific for each maneuver. Supporting the illustrations, presented as a slide show, there will be a guiding voice-over that will enunciate the moves to be executed. The software will allow to activate a hands-off mode.

Specifically:

for the Heimlich maneuver the slides will show the maneuver executed by a specialist in cyclic manner;

for the cardiac massage, the slides will show the procedure following its cyclic nature and a button called“massage rhythm” will be present, which will allow to activate and deactivate the voice-over guide.

For both maneuvers, an area in the bottom part of the screen will be dedicated to an “emergency call” button which, once activated, will command the application 100 to contact rescue services immediately, requesting their intervention and initiating a video call to receive assistance. The GPS position, determined by the device, will automatically be communicated to the rescue services.

The logic flow and the sequence of screens of the application 100 are shown in FIG. 5. The graphic interface is conceived to maximize usability and greatly emphasizes simplicity of use. The main menu 110 will present the user with the choice between the two modes (practice and emergency). Selecting the practice mode, the available maneuvers 120 or the option to return to the main menu will then be shown. To each maneuver will correspond a dedicated screen 130 that will contain the illustrative video 131 and a preview of the track 132 produced starting from the data of the accelerometer during the practice session. Selecting the emergency mode, similarly, the user will be presented with the choice of the maneuver 140, upon completion of which the application will go to the guidance/assistance mode, showing the correct sequence to be carried out 151 and the buttons in the bottom part of the screen. For cardiopulmonary resuscitation, a“rhythm” button 152 will be active. The “emergency call” button 153 instead is always present, irrespective of the selected maneuver. Lastly, the proposed embodiment provides an appropriate tool for loading and developing maneuver models. The tool, which will be displayed as an additional functionality in the main menu, will enable users to:

insert on the device, by downloading, further first aid procedures in the form of pre- compiled reference models;

downloading updates of the stored procedures and additional multimedia contents; develop reference models of new maneuvers through the activation of a special “recording” mode, through which the device will be able to store the movements executed by an expert.

The additional reference model, both pre-compiled, and developed anew, may then be used - in practice mode - to train the user.

Lastly, it is clear that the invention described hitherto can be subject to modifications, additions or variants which are obvious for a person skilled in the art, without thereby departing from the scope of protection that is provided by the claims.
