Field of invention More specifically, the invention concerns a system that includes a wearable device, studied and created in particular to be integrated into a garment, such as a military uniform, or public safety operators, but which can be used for any application, which is necessary have immediate control of occlusion systems of blood flow to be able to counteract a hemorrhage. In the following the description will be addressed to a wearable system integrated into a vest bulletproof, but it is quite clear that the same is not should be considered limited to this use specific. Known technique A first known type solution of a device to stop bleeding involves a ring and four Separate clamps with rubber pads. Each clamp It is equipped with two knee pads for movement with respect to to the ring. The ring has two guide openings for each clamp and corresponding adjustment screws. One disadvantage of this solution is that the AT / GLP [A591521] device must necessarily be applied on the injured by another person. Therefore, a subject is unable from using this device without it being helped by other subjects. An additional disadvantage is that such a device is specifically configured for bleeding in the extremities and it is not able to intervene on hemorrhages of the trunk, nor does it have the flexibility to adapt to the trunk. A second solution of a known type concerns a compression control device a hemorrhage. This solution includes a device portable, belt-like device of small size which contains multiple inflatable air chambers. The chambers inflatable air balloons are positioned and inflated selectively on the bled blood vessels, thus applying pressure to stop the bleeding. The device can also be used to provide supplemental perfusion in low-risk pathological states flow such as hemorrhagic shock and cardiac arrest. One disadvantage of this solution is that this too device must necessarily be applied on the injured by another person. Therefore, even in this case, an injured subject is unable to use this device without being helped by other subjects. As is well known, tourniquets are devices capable of stopping a hemorrhage from a limb. Also known is a tourniquet comprising AT / GLP [A591521] a flat, non-elastic band with a closure Velcro. This tourniquet includes straps reinforcement in the internal cavity of the flat band not elastic on both sides of the same. One end of the flat band is fixed to a strap of block under which an elastic pad is fixed, while the other end of the flat band is connected to a locking tab equipped with an elastic band. A disadvantage of this solution is once again that the device described must necessarily be applied to the wound by another person. Therefore, even in this case, an injured subject is unable to use such device without be helped by other people. An additional disadvantage is that this system is not in able to intervene on trunk hemorrhages. Another solution of a known type is an apparatus haemostatic device with automatic control function hemostatic pressure. This hemostatic apparatus is used for hemostasis of a bleeding area includes a cuff that is worn around a nearby part of the body to the bleeding area and expands with injected air to generate hemostatic pressure. This device includes a pressure sensor that detects hemostatic pressure and a pressure pump connected to the cuff through a pneumatic line, which is operated according to a control signal to inject air into the cuff. One disadvantage of this known type of solution is that the device must necessarily be applied on the wound from another person, and which prevents a AT / GLP [A591521] subject can use it without help from others. An additional disadvantage is that this device is not configured to stop truncal bleeding. Furthermore, this device requires a system of control that inflates the headphones, which must be powered by a pump. Therefore, this apparatus requires power supply, making the device itself not very flexible and in fact preventing its portability. In addition, further solutions of known type have the disadvantage of using substances, for example example anticoagulants, which must be applied on the injured area. Also known are mechanical devices that require the presence of another person who applies them on the injured subject, and / or essentially devices based on medical technologies such as electrocoagulation, which require specialized technical preparation and are available only to medical personnel in specific environments. It is evident that this procedure is expensive. in terms of time and safety, especially for those exploratory missions in which a subject is isolated or for events where it is vital to proceed to stop the bleeding. Also evident is the need to provide a solution capable of meeting a plurality of injuries as quickly as possible. Purpose of the invention In light of the above, it is, therefore, the purpose of the The present invention overcomes said disadvantages by providing AT / GLP [A591521] a solution for the control of bleeding limbs and trunk following traumatic injuries. A further object of the present invention is to provide a wearable device that can be integrated into clothing, for example in a soldier's uniform. A further object of the present invention is provide a device for bleeding control able to function without the need for power sources external power supplies, being activated autonomously by the person themselves or remotely, for example from centers dedicated control. Subject of the invention These and other results are obtained according to the invention with a wearable system for arresting hemorrhages. It is therefore the specific subject of this invention of a wearable system capable of modifying the own configuration to counteract a hemorrhage of a subject wearing said system.

It is therefore the specific subject of this invention of a wearable system for arresting hemorrhages as defined in claim 1. Preferred embodiments are defined in the dependent claims. Brief description of the figures The present invention will now be described by way of example. AT / GLP [A591521] illustrative but not limiting, according to your preferences embodiments, with particular reference to figures of the attached drawings, in which: Figure 1 shows, in front view, a form of realization of a wearable system for the arrest of hemorrhages, object of the present invention, equipped with a plurality of hemostatic cuffs arranged at the root of the limbs of a subject wearing the system, and equipped with a pair of airbags in the trunk of the said subject; Figure 2 shows, in side view, the system wearable of figure 1; and Figure 3 shows a flowchart of the operation of an embodiment of a system wearable device for stopping bleeding, subject of the present invention. Detailed description In the various figures the similar parts will be indicated with the same numerical references. Referring to figure 1, a Wearable S-System for stopping bleeding. The S system essentially comprises a body of support 1 and at least one passive safety device 3 able to expand. Referring to figures 1 and 2, the system S comprises a support body 1, a pair of devices passive safety 31, 32, and a variety of headphones hemostatic 2. Although, both figures show this embodiment, other forms of implementation of the S system is foreseen. In AT / GLP [A591521] in particular, the S system may or may not be equipped with one or more hemostatic cuffs. As can be seen from figure 1, the plurality of Hemostatic Cuffs 2 includes four cuffs hemostatic 21, 22, 23, 24 each arranged in a such as to wrap around the root of a corresponding limb of the subject wearing the S system. Also said at least one safety device passive 3 able to expand is preferably a small airbag, which is placed between the said supporting body 1 and the subject's trunk, for example in contact with an internal face 11 of said body of support 1. Said passive safety device 3, in particular, it is able to expand as a result of a impact and / or an external command, so as to to counteract a hemorrhage of a subject wearing called S system. This impact can be an impact suffered by the subject wearing the S system, for example undergoing against a weapon, a sharp object, a projectile, or another type of trauma that causes bleeding. This external command can be operated by the same subject wearing the S system, so controlled, autonomous. In some embodiments, as described In the following, this command can be automated. Said internal face 11 is preferably rigid in so as to define the area in which said at least one passive safety device 3 can expand. AT / GLP [A591521] With reference to figures 1 and 2, the body of Wearable support 1 is a central body that covers the torso of a subject wearing the S system, the latter equipped with a safety device upper passive, or upper airbag, 31 arranged in correspondence of an upper portion of said body support 1 and a passive safety device lower, or lower airbag, 32 arranged in correspondence of a lower portion of said body support 1. Said upper airbag 31 is configured to swell and compress an upper portion of the trunk 3, while the lower airbag 32 is configured to inflate and compress a lower portion of the trunk and the abdomen. Referring to figure 1, the system S includes a wearable bulletproof vest, equipped with a bulletproof plate 12. Said bulletproof plate 12 is preferably rectangular in shape and has a size such as to cover the chest and abdomen of a subject who wears. Referring to figure 1, a embodiment of the integrable S system, ad for example, in a soldier's combat uniform. This solution includes the creation, inside the uniform, specifically pockets shaped to accommodate 2 headphones and / or at least one airbag 3. In some embodiments, said pockets are AT / GLP [A591521] sized to accommodate inflation devices and activation of each headphone 2, 21, respectively 22, 23, 24, and of each passive safety device 3 capable of expansion. These pockets are made so as to keep the devices in the area in the which must be active, so that the inflation allows for compression to be achieved in the desired areas, without each cuff 2, or airbag 3 deviates from the area of ​​interest. The plurality of hemostatic cuffs 2 is intended to control bleeding in the limbs due to wounds, and can be integrated into special pockets made inside the uniform, preferably at the root of the limbs. This allows compression to be performed efficiently, reducing blood flow to the root itself. The presence of these pockets allows the insertion or the removal of each cap 21, 22, 23, 24 where applicable necessary, for example, to wash the uniform or change a specific headset. Preferably, the plurality of hemostatic cuffs 2 has dimensions appropriate to the size of the uniform in such a way as to ensure, once inflated, that the limb is subjected to a pressure equal to 140 mm Hg, enough to stop the flow of blood in the limb. The S system may include a pressure sensor and a pressure modulation mechanism itself, so that at least one headset 21, 22, 23, 24 can be connected to the pressure sensor to operate the applied pressure modulation mechanism AT / GLP [A591521] to the limb. Where bleeding causes a drop in blood flow blood pressure due to decreased volume circulating, said modulation mechanism can be modified, for example a value of can be set pressure threshold equal to 140 mm Hg, or different. In this way, the S system, by blocking the bleeding in the limbs, can maintain blood flow in favor of vital organs, for example, the trunk, or the brain. Therefore, the S system can be an aid for the prolongation of the maintenance of vital functions of the injured, or in extreme situations. The S system, being wearable and integrable to a bulletproof plate 12, it is easy to use for law enforcement and / or military, as it is part of the equipment of the combat uniforms, a bulletproof plate. In this context, the use of the S system does not cause additional bulk compared to a standard bulletproof plate. The S system may feature additional pockets sized to accommodate airbags 31, 32 respectively for the upper and lower part of the trunk. These pockets can be sewn or heat sealed to a uniform, for example in correspondence with zones covered by bulletproof plate 12 to make sure that they remain intact, protected from possible breakages until they are supposed to activate. In some embodiments, the shape of each airbag 31, 32 and the corresponding pocket AT / GLP [A591521] ensures that in the event of an injury to the upper part of the trunk or abdomen, that is, areas not covered by the bulletproof plate 12, each airbag 31, 32, by swelling, it can exert pressure on the body, adequate to contain blood loss. The S system preferably includes means for automatic activation of the headphones 2 and / or the airbags 3. In particular, automatic activation occurs using a container of compressed air or other gas compressed which can have the shape of a micro-cylinder or micro-pump, or by means of a device that operates the flow of air or gas inside each cuff 21, 22, 23, 24 and / or each airbag 31, 32 to ensure their inflation. The S system can also include the presence of a controller 4, such as a remote control to manage the activation of each headphone 21, 22, 23, 24, e / p of each airbag 31, 32. In some examples, the activation of the device inflation can be done via a control that can be operated by part of the military, for example through the said controller 4. Controller 4 can be provided with a circuit protection that prevents involuntary activation or remotely, for example, via actuators connected to the military communication devices. In some embodiments, the S system includes one or more sensors that detect certain parameters of the subject wearing the S-system, for example sensors which detect the subject's vital parameters. AT / GLP [A591521] Such sensors may comprise a plurality of pressure sensors to determine pressure arterial in multiple areas of the subject's body, or one or multiple inertial sensors, or one or more accelerometers. In some embodiments, the inflation device can be controlled in a such as to simultaneously activate the plurality of headphones 2 and airbags 31, 32 in the event of certain conditions such as a drop in soldier's blood pressure recorded on time real from sensors, or from a monitoring device inserted into the uniform, or into a combat suit. Other conditions that trigger inflation of the headphones 2 and airbags 3 may include the detection of a prone position of the soldier maintained over a long period of time and detected by an inertial measurement unit capable of recording, a complete immobility of the body for a period of time default. Furthermore, in some embodiments a accelerometer, or other acceleration sensor inertial, can detect an acceleration such as to be intended or associated with the receipt of a projectile from part of the subject. Preferably, the S system, for example at controller level 4, provides a trigger or a button to activate the occlusion of a headphone 21, 22, 23, 24 and / or for the expansion of one or both called airbags 31, 32. This trigger can be a button, or a pushbutton. AT / GLP [A591521] which allows manual activation of the S system, so that the subject can independently activate the swelling following a haemorrhage, without the need supporting other subjects. A preferred embodiment includes the presence of a plurality of pressure sensors, remotely connected to controller 4, which is activates autonomously when certain conditions occur, for example when there is a rapid drop in pressure and / or a drop in pressure below a pressure minimum acceptable. Similarly, the system may include a module of remote connection with a remote control center that receives data from pressure sensors and / or inertial sensors, compares the received data with certain threshold values ​​and produces a response. This answer can be to keep the headphones 2 and the airbag 3, inactive, if the data received meets certain conditions, for example, are lower than their respective threshold values, or send an alarm signal if the received data meets certain conditions and sends a command or instructions to activate the inflation of a or more headphones 2, and / or at least one airbag 31, 32. The alarm signal can be an audible signal, visual, or another type of signal, even remote, that is sent to the remote control center. The numerical reference 14 indicates a pair of load straps, or braces with which said S system can be worn underneath or over of a uniform. AT / GLP [A591521] Referring to figure 2, a abdominal strap 15 to a chest strap 16 which they allow the weight to be distributed, even if limited, of the S system. The operation of the S system described above is It works as follows. When a subject is hit by a bullet in an area not protected by a bulletproof plate, for example to a limb, in the upper part of the trunk near the head, or at the abdominal level, the subject wearing the S system can activate the system S by means of an external command. In some embodiments, the command external is given by a small lever, or by a cable from pull placed in a position accessible to the subject same. In some examples, the S system provides a lever or cable for each headset and each airbag. In some embodiments, the command external is performed by a controller 4, such as for example a remote control, or an application that manages remotely, for example through a technology wireless transmission, each headphone 21, 22, 23, 24, and / or each airbag 31, 32. Referring to figure 3, it is shown the operation of an embodiment of the system S, wherein said system S is equipped with a plurality of sensors. The system receives, from at least one sensor, one or more parameters of a subject wearing the system AT / GLP [A591521] S. The reception of parameters can be programmed in way to record and send data at intervals of regular time. The data is sent to a controller 4 or to a remote control center, or command center, which manages the S system. At this point, controller 4 compares the data received, for example linked to vital signs of the subject, or relating to the integrity of the headphones 2 and the airbag 3, with predetermined threshold values. In this way, controller 4 checks whether the parameters satisfy predetermined conditions. Especially when the parameters meet predetermined conditions, for example they fall within acceptable values ​​of vital signs, and / or data relating to headphones 2 and airbag 3 do not show any faults, controller 4 maintains the same instructions as control of said at least one safety device passive 3 and / or at least one hemostatic cuff 2. If, on the basis of the comparison, there is a difference sufficient to highlight a health risk of the subject, an alarm is automatically generated, in so as to alert any subjects in the vicinity, to inform a remote control center, or a reference station. At the same time, controller 4, or the center of remote control update instructions to control an expansion of at least one safety device passive 3 and / or an occlusion of at least one cuff hemostatic 2. If the bleeding is localized and of large quantity moderate, controller 4 will tend to activate the headset AT / GLP [A591521] hemostatic 2 and / or airbag 3 closest to the bleeding. In more severe cases, determined by the detection of more sensors, it is expected that the controller 4 activates more headphones and / or airbags at the same time. Advantages Advantageously, the invention allows to stop or stem bleeding from wounds to the limbs or body, being manually activated by the same injured operator or at a distance from a center of command, or automatically when certain events occur conditions. An additional advantage is that it allows you to extend the survival of a soldier, even seriously injured, as well as to carry out such action without the intervention of other people, which may not be not immediately feasible due to conditions hostile operations. Another advantage is having more time for the planning and implementation of an intervention of medical evacuation. Although of obvious benefit in the case of operators military, this invention can be usefully employed also in support of other people engaged in other dangerous activities in which they might go sustaining serious injuries resulting in loss of blood. The present invention has been described by way of example. illustrative, but not limiting, according to its forms preferred to be made, but it is to be understood that changes and / or modifications may be made by the AT / GLP [A591521] experts in the field without however departing from the relevant scope of protection, as defined by the claims attached.
