Description

[0001] Wearable system to stop the bleeding

[0002] *****

[0003] The present invention relates to the arrest of hemorrhages caused by traumatic injuries, in particular a system that can be worn and integrated into military uniforms or integrated into other uniforms, which allows, in a rapid and safe manner, the arrest of hemorrhages in the limbs or torso resulting from traumatic injuries. Field of invention

[0004] More specifically, the invention concerns a system that comprises a wearable device, designed and manufactured, in particular, to be integrated into clothing, for example in a military uniform, or that of public safety operators, but which can be used for any application in which it is necessary to have immediate control of blood flow occlusion systems in order to counteract a hemorrhage.

[0005] In the following, the description will be addressed to a wearable system integrated into a bulletproof vest, but it is clear that the same should not be considered limited to this specific use.

[0006] Prior art

[0007] A first known type of hemorrhage arrest device solution consists of a ring and four separate clamps with rubber pads. Each clamp has two knee pads for movement relative to the ring. The ring has two guide openings for each clamp and corresponding adjustment screws.

[0008] A disadvantage of this solution is that the device must necessarily be applied to the wound by another person.

[0009] Therefore, a subject is unable to use such a device without the help of other subjects.

[0010] An additional disadvantage is that this device is specifically configured for limb hemorrhages and is not capable of intervening on torso hemorrhages, nor does it have the flexibility to adapt to the torso as well.

[0011] A second known solution is a device for controlling the compression of a hemorrhage. This solution comprises a portable, belt-like device of small dimensions that contains multiple inflatable air chambers. The inflatable air chambers are positioned and inflated selectively on the bleeding vessels, thereby applying pressure to stop the hemorrhage. The device can also be used to provide supplemental perfusion in low-flow pathological states such as hemorrhagic shock and cardiac arrest. A disadvantage of this solution is that this device must also necessarily be applied to the wound by another person.

[0012] Therefore, even in this case, an injured subject is unable to use this device without the help of other subjects.

[0013] As is well known, tourniquets are devices capable of stopping a hemorrhage in a limb.

[0014] Also known is a tourniquet comprising a flat, non-elastic band with a Velcro closure. This tourniquet comprises reinforcing straps in the internal cavity of the flat, non-elastic band on both sides of the band. One end of the flat band is attached to a locking strap, under which an elastic pad is attached, while the other end of the flat band is connected to a locking tab provided with an elastic band.

[0015] A disadvantage of this solution is once again that the described device must necessarily be applied to the wound by another person.

[0016] Therefore, even in this case, an injured person is not able to use such a device, but rather needs to be helped by other people.

[0017] An additional disadvantage is that this system cannot intervene on torso hemorrhages.

[0018] Another known solution is a hemostatic apparatus having the function of automatically controlling the hemostatic pressure. Said hemostatic apparatus for hemostasis of a bleeding area includes a cuff that is worn around a part of the body near the bleeding area and expands with injected air to generate hemostatic pressure. Such apparatus includes a pressure sensor that detects the 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.

[0019] A disadvantage of this known solution is that the device must necessarily be applied to the wound by another person, and that it prevents a subject from using it independently.

[0020] An additional disadvantage is that this device is not configured to stop truncal hemorrhages.

[0021] Furthermore, this apparatus requires a control system that inflates the cuffs, which must be operated by an external pump. Therefore, this device requires power supply, making the device itself not flexible and in fact preventing its portability.

[0022] Furthermore, other known solutions have the disadvantage of using substances, such as coagulants, which must be applied to the injured area. Also known are mechanical devices that require the presence of another person to apply them to the injured subject, and / or devices essentially based on medical technologies such as electrocoagulation, which require specialized technical training and are only available to medical personnel in specific environments.

[0023] It is apparent 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 in which it is vital to proceed with the arrest of the hemorrhage in emergency conditions.

[0024] Equally evident is the need to provide a solution capable of remedying a plurality of lesions in the shortest possible time.

[0025] Purpose of the invention

[0026] In light of the above, it is therefore the aim of the present invention to overcome said disadvantages by providing a solution for the control of bleeding in the limbs and the torso following traumatic injuries.

[0027] A further purpose of the present invention is to provide a device that can be worn and integrated into clothing, for example into a military uniform.

[0028] A further object of the present invention is to provide a device for the control of hemorrhages capable of operating without the need for external power sources, being activated autonomously by the person himself or remotely, for example from dedicated control centers.

[0029] Object of the invention

[0030] These and other results are achieved according to the invention with a wearable system for stopping hemorrhages.

[0031] The specific object of the present invention is therefore a wearable system capable of modifying its configuration to counteract a hemorrhage in a subject wearing said system. In particular, a hemorrhage control system comprising a bulletproof vest having an internal face that, when in use, faces a subject wearing the bulletproof vest, having one or more pockets formed in said internal face.

[0032] When the system is in use, the pockets are arranged in proximity to the shoulders and / or hips of a subject wearing said bulletproof vest, which comprises at least one wearable passive safety device, in contact with said internal face, wherein said passive safety device is capable of expanding upon impact and / or external control, in such a way as to counteract a hemorrhage of a subject wearing said system. Furthermore, the bulletproof vest comprises at least one hemostatic cuff operatively connected to said bulletproof vest and configured to envelop a portion of a limb of the subject, and to occlude blood flow to said limb following impact and / or external control. Said passive safety device and said at least one hemostatic cuff are arranged, when not in use, inside said one or more deformable pockets, and said one or more deformable pockets comprise a means of correspondingly inflating and activating said passive safety device and said at least one hemostatic cuff.

[0033] Still according to the invention, the specific object of the present invention is a computer program comprising instructions for controlling the operation of said system.

[0034] The specific object of the present invention is therefore a wearable system for stopping hemorrhages as defined in claim 1 .

[0035] Preferred embodiments are defined in the dependent claims.

[0036] Brief description of the figures

[0037] The present invention will be now described, for illustrative but not limitative purposes, according to its preferred embodiments, with particular reference to the figures of the enclosed drawings, wherein: figure 1 shows, in front view, an embodiment of a wearable system for stopping 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 corresponding to the torso of said subject; figure 2 shows, in a lateral view, a wearable system for hemorrhage arrest, object of the present invention; figure 3 shows, in a lateral view, the system of figure 2, worn by a subject, and activated; figure 4 shows, in a perspective view, a bulletproof vest comprised in the system of the present invention; and figure 5 shows a flowchart of the operation of one embodiment of a wearable bleeding arrest system, which is the subject of the present invention.

[0038] Detailed description

[0039] In the various figures, similar parts will be indicated with the same numerical references.

[0040] Referring to figure 1 , a wearable system S for hemorrhage arrest is shown.

[0041] The system S essentially comprises a support body 1 and at least one passive safety device 3 capable of expanding.

[0042] With reference to figures 1 and 2, the system S comprises a support body 1 , a pair of passive safety devices 31 , 32, and a plurality of hemostatic cuffs 2. Although both figures show this embodiment, other embodiments of the system S are provided. In particular, the system S may or may not be equipped with one or more hemostatic cuffs.

[0043] As can be seen from figure 1 , the plurality of hemostatic cuffs 2 comprises four hemostatic cuffs 21 , 22, 23, 24 each arranged in such a way as to wrap around the root of a corresponding limb of the subject wearing the system S.

[0044] Furthermore, said at least one passive safety device 3 capable of expansion is preferably an airbag of small dimensions, which is positioned between said support body 1 and the torso of the subject, for example in contact with an internal face 11 of said support body 1 .

[0045] Said passive safety device 3, in particular, is able to expand as a result of an impact and / or an external command, in such a way as to counteract a hemorrhage of a subject wearing said system S.

[0046] Such impact may be an impact suffered by the subject wearing the system S, such as a weapon, a sharp object, a bullet, or other type of trauma that causes bleeding.

[0047] This external command can be activated by the same person wearing the system S, in a controlled, autonomous manner.

[0048] In some embodiments, as described below, said command may be automated.

[0049] Said internal face 11 is preferably rigid, so as to define the area in which said at least one passive safety device 3 can expand.

[0050] With reference to figures 1 and 2, the wearable support body 1 is a central body that covers the torso of a subject wearing the system S, the latter equipped with an upper passive safety device, or upper airbag, 31 arranged in correspondence with an upper portion of said support body 1 , and a lower passive safety device, or lower airbag, 32 arranged in correspondence with a lower portion of said support body 1 .

[0051] Said upper airbag 31 is configured to inflate and compress an upper portion of the torso 3, while the lower airbag 32 is configured to inflate and compress a lower portion of the torso and abdomen. Referring to figures 2 and 3, a third airbag 3 is positioned between the upper airbag 31 and the lower airbag 32, in order to ensure greater action on the entire torso of the subject wearing the system S.

[0052] Referring to Figure 1 , the system S comprises a wearable bulletproof vest, equipped with a bulletproof plate 12.

[0053] Said bulletproof plate 12 is preferably rectangular in shape and has a size such as to cover the chest and abdomen of a subject wearing it.

[0054] Preferably, the bulletproof vest 1 comprises a bulletproof plate 12 made of ultra-high molecular weight polyethylene, also called UHMWPE, or steel. Ultra-high molecular weight polyethylene, as is known, has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million u.m.a. (or Daltons). The bulletproof plate 12 may include additional materials capable of combining lightness and protection of the wearer.

[0055] The plate preferably has a thickness between 20 mm and 30 mm, so as to protect the subject from a bullet or an attack with bladed weapons.

[0056] With reference to figure 1 , an embodiment of the system S is shown that can be integrated, for example, into a soldier’s combat uniform.

[0057] This solution involves the creation, inside the uniform, of pockets 5 specifically shaped to house the cuffs 2 and / or at least one airbag 3.

[0058] In some embodiments, said pockets 5 are sized to house devices or means for inflating and activating each cuff 2, 21 , 22, 23, 24, and each passive safety device 3 capable of expansion, respectively. Such pockets 5 are made in such a way as to keep the devices in the area in which they are to be active, so that inflation allows compression to be achieved in the desired areas, without each cuff 2, or airbag 3 moving away from the area of interest.

[0059] Said means of inflating and activating said passive safety device and said at least one hemostatic cuff may comprise a latch 4’, a switch, a trigger, or the like to instantaneously activate, for example, one or more compressed air containers and / or battery-powered micro-pumps, so as to inflate the passive safety device 3 and at least one hemostatic cuff 2.

[0060] The plurality of hemostatic cuffs 2 is intended for the control of bleeding of 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 very root. The presence of these pockets allows the insertion or removal of each cap 21 , 22, 23, 24 where necessary, for example, to wash the uniform or change a specific cap.

[0061] Preferably, the plurality of hemostatic cuffs 2 are sized appropriately to the size of the uniform, to ensure, once inflated, that the limb is subjected to a pressure of 140 mm Hg, sufficient to stop the flow of blood in the limb.

[0062] Examples of the said system S include hemostatic cuffs 2 placed at the height of the upper limbs, for example, 20 mm high and 300 mm long, and additional hemostatic cuffs 2 dedicated to the lower limbs, 20 mm high and 550 mm long. Once inflated, these cuffs can reach a volume of approximately 60 cm3respectively, for the upper limbs and 110 cm3for the lower limbs, to ensure that the limb is subjected to sufficient pressure to stop the blood flow, approximately between 140 mm Hg and 160 mm Hg.

[0063] The system S may comprise a pressure sensor and a pressure modulation mechanism, so that at least one cuff 21 , 22, 23, 24 may be connected to the pressure sensor to operate the pressure modulation mechanism applied to the limb.

[0064] Where hemorrhages cause a drop in blood pressure due to a decrease in circulating volume, this modulation mechanism can be modified, for example a pressure threshold value of 140 mm Hg, or a different one, can be set.

[0065] In this way, the system S, by blocking bleeding in the limbs, can maintain blood flow to vital organs, such as the torso or the brain.

[0066] Therefore, the system S can be an aid in prolonging the maintenance of the injured person’s vital functions, or in extreme situations.

[0067] The system S, being wearable and integrable with a bulletproof plate 12, is easy to use for law enforcement and / or military forces, as it is part of the equipment of combat uniforms, a bulletproof plate. In this context, the use of the system S does not cause additional bulk compared to a standard bulletproof plate.

[0068] The system S may feature additional pockets 5 sized to accommodate airbags 31 , 32 for the upper and lower torso respectively.

[0069] These pockets 5 can be sewn or heat-sealed to a uniform, for example in correspondence with areas covered by the bulletproof plate 12 to ensure that they remain intact, protected from possible breakages until the moment in which they should be activated.

[0070] According to some embodiments, the shape of each airbag 31 , 32 and the corresponding pocket ensures that, in case of an injury to the upper part of the torso or abdomen, i.e. , areas not covered by the bulletproof plate 12, each airbag 31 , 32, by inflating, can exert a pressure on the body, suitable to contain the loss of blood.

[0071] The system S preferably comprises means for the automatic activation of the cuffs 2 and / or the airbags 3. In particular, the automatic activation occurs by means of a container of compressed air or other compressed gas, which may have the form of a micro-cylinder or micro-pump, or by means of a device, which activates the flow of air or gas inside each cuff 21 , 22, 23, 24 and / or each airbag 31 , 32 to ensure their inflation.

[0072] The compressed air container is preferably made of expanded polytetrafluoroethylene ePTFE or comprises other small reservoirs of soft material that inflate the strategically placed 3 airbags to achieve effective hemostasis. In fact, expanded polytetrafluoroethylene is a highly resistant and biocompatible material, often used in medical and industrial devices for its controlled porosity and air permeability. Its porous structure makes it suitable for applications such as filtration, ventilation and waterproof barriers.

[0073] The presence of internal pockets provides greater protection for the airbags 3 from possible breaks. The arrangement of the compressed air container in the pockets makes the system S more stable and more comfortable to carry than systems equipped with high-pressure cylinders. Therefore, it has the dual advantage of being lighter and does not present the risk of explosion to which high- pressure cylinders are subject.

[0074] The system S may also comprise the presence of a controller 4, for example a remote control to manage the activation of each cuff 21 , 22, 23, 24, and / or each airbag 31 , 32.

[0075] In some examples, the activation of the inflation device can occur via a command that can be operated by the soldier, for example via said controller 4.

[0076] The controller 4 may be provided with a protection circuit that excludes involuntary or remote activation, for example, by actuators connected to the soldier’s communication devices.

[0077] In some embodiments, the system S comprises one or more sensors that detect some parameters of the subject wearing the system S, for example sensors that detect vital parameters of the subject.

[0078] Such sensors may comprise a plurality of pressure sensors to determine blood pressure in multiple areas of the subject’s body, or one or more inertial sensors, or one or more accelerometers.

[0079] According to some embodiments, the inflation device can be controlled so as to simultaneously activate the plurality of cuffs 2 and the airbags 31 , 32 when certain conditions happen, such as a drop in the soldier’s blood pressure recorded in real time by the sensors, or by a monitoring device inserted in the uniform, or in a combat suit.

[0080] Other conditions that activate the inflation of cuffs 2 and airbags 3 may comprise the detection of a prolonged lying position of the soldier, detected by an inertial measurement unit, capable of recording complete immobility of the body for a predefined period of time.

[0081] Additionally, in some embodiments an accelerometer, or other inertial acceleration sensor, may detect an acceleration that is intended or associated with the subject’s receipt of a projectile.

[0082] Preferably, the system S, for example at the level of the controller 4, provides a trigger or a button for activating the occlusion of a cuff 21 , 22, 23, 24 and / or for the expansion of one or both of said airbags 31 , 32.

[0083] This trigger may be a button, or a push-button that allows manual activation of the system S, so that the subject can independently activate the inflation following a hemorrhage, without the need for support from other subjects.

[0084] A preferred embodiment provides for the presence of a plurality of pressure sensors, remotely connected to the controller 4, which autonomously activates when certain conditions occur, for example when there is a quick drop in pressure and / or a drop in pressure below a minimum acceptable pressure.

[0085] Similarly, the system may comprise a remote connection module with a remote control center that receives data from the pressure sensors and / or inertial sensors, compares the received data with certain threshold values and produces a response. Such response may be keeping the cuffs 2 and the airbags 3 inactive if the received data satisfy certain conditions, for example if they are lower than the respective threshold values, or to send an alarm signal if the received data satisfy certain conditions and sends a command or instructions to activate the inflation of one or more cuffs 2, and / or of at least one airbag 31 , 32.

[0086] The alarm signal can be an audible, visual, or other type of signal, even remote, which is sent to the remote control center. The reference number 14 indicates a pair of load straps, or braces with which said system S can be worn under or over a uniform.

[0087] Referring to figures 2, 3, and 4, an abdominal strap 15 and a chest strap 16 of the bulletproof vest shown in figure 4 are shown, which allow the weight, although limited, of the system S to be distributed.

[0088] The operation of the system S described above is as follows.

[0089] When a subject is hit by a bullet in an area not protected by a bulletproof plate, such as a limb, the upper part of the torso near the head, or at the abdominal level, the subject wearing the system S can activate the system S by means of an external command.

[0090] In some embodiments, the external control is given by a small lever, or by a pull cord placed in a position accessible to the subject himself.

[0091] In some examples, the system S provides a lever or cable for each cuff and each airbag.

[0092] In some embodiments, the external control is performed by a controller 4, for example a remote control, or an application that remotely manages, for example by means of wireless transmission technology, each cuff 21 , 22, 23, 24, and / or each airbag 31 , 32.

[0093] Referring to figure 5, the operation of an embodiment of the system S is shown, wherein said system S is equipped with a plurality of sensors.

[0094] The system receives, from at least one sensor, one or more parameters of a subject wearing the system S. The reception of the parameters can be programmed in order to record and send data at regular time intervals. The data are sent to a controller 4 or to a remote control center, or command center that manages the system S.

[0095] At this point, the controller 4 compares the received data, for example related to the subject’s vital parameters, or related to the integrity of the cuffs 2 and the airbags 3, with predetermined threshold values. In this way, the controller 4 verifies whether the parameters satisfy predetermined conditions.

[0096] In particular, when the parameters satisfy predetermined conditions, for example they fall within acceptable values of vital parameters, and / or the data relating to cuffs 2 and airbag 3 do not show any faults, the controller 4 maintains the same control instructions for said at least one passive safety device 3 and / or at least one hemostatic cuff 2. If, based on the comparison, there is a difference such as to highlight a risk to the subject’s health, an alarm is automatically generated, in order to alert any subjects in the vicinity, to inform a remote control center, or a reference station.

[0097] At the same time, the controller 4, or the remote control center updates the instructions to control an expansion of at least one passive safety device 3 and / or an occlusion of at least one hemostatic cuff 2. If the hemorrhage is localized and of moderate quantity, the controller 4 will tend to activate the hemostatic cuff 2 and / or the airbag 3 closest to the hemorrhage. In more serious cases, determined by the detection of multiple sensors, the controller 4 is expected to activate multiple cuffs and / or airbags simultaneously.

[0098] Advantages

[0099] Advantageously, the invention allows to stop or stem bleeding due to wounds to the limbs or body, being activated manually by the injured operator himself or remotely from a command center, or automatically when certain conditions occur.

[0100] An advantage of the present invention is to provide a system having a bulletproof plate vest equipped, inside it, with an apparatus capable of operating without the need for external power sources. In fact, the system can be activated autonomously by the person wearing it, or by a rescuer present on site, or by a remote control center.

[0101] An additional advantage is that it allows for the survival of a soldier, even if seriously injured, to be prolonged, as well as to carry out such an action without the intervention of other people, which may not be immediately feasible due to hostile operating conditions.

[0102] Another advantage is having more time to plan and carry out a medical evacuation intervention.

[0103] While obviously beneficial to military personnel, this invention may also be usefully employed to support other people engaged in other dangerous activities in which they may sustain serious injuries resulting in blood loss.

[0104] The present invention has been described for illustrative but not limitative purposes, according to its preferred embodiments, but it is to be understood that modifications and / or changes can be introduced by those skilled in the art without departing from the relevant scope as defined in the enclosed claims.
