Description

The present invention relates to a portable device in the form of a textile-integrated protection system according to the preamble of the first claim.The invention is not limited to the features defined in the claims. Rather, further technical configurations are described that are not claimed, but are fully disclosed to provide alternative or supplemental embodiments.The invention lies in the field of medical emergency equipment, personal protective equipment (PSA) and textile technology and is intended in particular for applications in military, official and civil risk situations.Hemostatically active materials are known from the prior art, for example based on kaolin, chitosan, silver ions or bioactive nanostructures, which are usually available in the form of compresses, gel pads or applicators.For example, EP 1731175 B1 describes hemostatic cross-linked dextran beads which are used for rapid blood clotting and hemostasis. The administration form can be effected by means of creams, lotions and / or emulsions and can be contained in a transdermal patch of the matrix or reservoir type.In document EP 3 785 753 B1 a device for dispensing hemostatic powder is disclosed, which comprises an elongated hollow reservoir, wherein a manual air pump is attached to the reservoir and an ejection opening is arranged at the distal end of the reservoir. A porous filter is provided slidably disposed in the reservoir between the air pump and the discharge port. Further, a spring is disposed in the reservoir between the air pump and the filter, the powder in the reservoir is disposed between the filter and the discharge port, and the pump is in fluid communication with the discharge port through the porous filter and through the powder.The document DE102016009877A1 discloses the construction of a "react protect package". A wound dressing is applied in the center of the package and / or a cushion / spring cushion is placed after the wound dressing in order to be able to dampen the wound from pressing it onto the sensitive and injured skin, to capture moisture (by wound dressing) and to filter soiled skin better (by wound dressing / filter layer). The barrier layer / barrier layer may be the next following layer to protect the ingredients from the environment during use and to allow the ingredients to be drawn in until drying out and action on the open or irritable skin. Subsequently, the wound dressing / filling space with the space puck or cannula filling supply wound dressing compartments can be used, in which the ingredients, the antiseptic, herbal cream mixture and the nitrogen can be contained. The space puck may once again have three fine chambers which can first release the antiseptic and / or the nitrogen and / or the herbal cream mixture. All the ingredients, materials and substances (constituents) mentioned in the plaster (React Protect Plasticizer) can likewise be used in the React Protect Package in a variable manner, including in many ways to be expanded and combined as desired.However, these products require manual application by medical professionals or first responders. Furthermore, smart textile concepts for controlled drug delivery or sensor technology integration have been studied, for example in the form of surgical dressings or reactive hydrogel textiles. However, these systems are not suitable for immediate hemostasis in traumatic, penetrating injuries under mobile or tactic conditions.In particular, the prior art lacks a textile-integrated or modular system that can act over a large or the entire body area in the event of a injury.It is an object of the invention to provide a portable device which automatically releases a hemostatically active material which immediately provides affected wound regions upon penetrating injuries. The device should be capable of being integrated completely or in modular fashion into textile structures, be distributed over anatomicalally endangered body zones, allow passive, pressure-difference-controlled active ingredient redistribution, be replaceable in a maintenance-friendly manner and allow manual removal of the active ingredient for external use. In addition, a sensor-based shot detection with optical or electronic feedback should optionally be integratable.This object is achieved by the features of the first claim.Advantageous embodiments are evident from the dependent claims.According to the invention, a portable device in the form of a textile-integrated protective system for passive hemostasis in the event of penetrating injuries is achieved, wherein the device has a plurality of chambers which contain a hemostatically active material and tear open in the event of mechanical perforation, so that the material exits from at least one chamber into a wound.In accordance with claim 2, inner side tearability of the chambersBy the targeted configuration of the chambers, so that they tear open only toward the inside of the item of clothing, a directed release of the hemostatic material is achieved. Technically, this has the effect that the material is guided directly to the wound in a minimizing manner and does not escape to the outside in an uncontrolled manner. This ensures that most of the active ingredient remains available where needed, thereby greatly improving hemostasis efficiency.In accordance with claim 3, a gel variant of the hemostatic materialThe use of a prefabricated viscous gel offers the technical advantage of immediate hemostasis because the gel adheres without delay, swells and forms a temporary seal of the wound. This is advantageous in particular in the case of high blood loss, since there is no waiting time for the activation of the material. The gel formulation also ensures that the material remains where it is released since it cannot drain off.In accordance with claim 4, a powder variant of the hemostatic materialA dry, gel-forming powder offers the technical contribution of increased storage stability and an improvement in climatic resistance. The powder remains stable at high and low temperatures, is lighter than gel and becomes active only upon contact with blood. This improves the operability in extreme environments and at the same time ensures that the hemostatic system functions reliably even in the case of prolonged storage.In addition to dependent claim 5, modularity and exchangeability of the chambersThe possibility of modular and toolless replacement of the chambers allows cost-effective maintenance and long serviceability of the protection system. This contributes technically to the system not being designed as a disposable article, but rather constituting a lasting solution. In addition, it increases flexibility of use since chambers can be exchanged or filled on site if required.In claim 6, microperforated connections for fluid flowThe connection of chambers via microperforated channels represents an innovative solution for the passive re-delivery of hemostatic material. By utilizing pressure differences, the material can automatically flow from intact chambers into an already damaged chamber. This increases safety and reliability, since active substance can continue to flow into the injured zone even after the initial release.In addition to dependent claim 7 and 8, manual removal deviceThe manual removal device extends the functionality considerably: in addition to the self-supply, the material can be removed in a targeted manner for the supply of third persons. This improves applicability in the tactic and civilian fields. Defined openings such as snap closures, membrane closures or tear-off valves make it possible to remove them reliably and hygienically.In addition to dependent claim 9-11, sensor system and displayThe integration of a sensor for detecting a chamber perforation represents a technical advance over purely mechanical systems. The injury can also be detected by resistance or strain sensors if it is not immediately noticeable (e.g. in the case of feeling of dewiness or in stress situations). In combination with an optical display unit (e.g. LED) and a wireless data transmission to a central station, an intelligent system results which immediately informs the emergency line and thus accelerates medical care.In accordance with claim 12, an integration as a piece of clothing or arrangement in a piece of clothingThe configuration of the device as a piece of clothing or the arrangement thereof within a piece of clothing brings considerable technical advantages. As a result of the textile integration, the hemostatic system is positioned directly on the body of the user, which drastically shortens the reaction time in the event of a severity. Unlike in the case of separately worn devices, there is no risk that the device is not hand in the case of use. In addition, the textile embedding allows an imperceptible and comfortable wear, whereby the acceptance in daily use-in particular in safety-relevant occupation groups or in the outdoor area-is increased. Technically, this solution has the effect that the protective function is always available on body, whereby a direct contact between wound and hemostatic material can be ensured without additional manipulations being necessary. This substantially optimizes the functionality and reaction speed in the event of injury.In accordance with dependent claim 13The integration of the chambers into a garment with crotch / pant part as well as the implementation of flexible separating regions considerably improve the ergonomy and the wearing comfort. The separating regions ensure unrestricted mobility without the chambers losing their function. This ensures that the protective effect is maintained even during movement (e.g. running, hocking).Further features of the solution according to the invention are described below:In addition to the claimed features according to patent claims 1 to 13, the invention comprises further technical configurations which are described by way of example below.Flexible Separation RegionsThe chambers can be connected by elastic or net-shaped separation regions which allow a particularly proximal arrangement. This design contributes to the chambers remaining stable even when moved intensively and at the same time ensuring high wearing comfort. In the region of the separation, the material selection ensures that a reliable activation of the hemostatic system also takes place there.Crotch Area or Pant PartA crotch portion or pant portion in the garment serves for additional fixation and allows further compartments to be incorporated for protection of the lower body regions (e.g., splint, inner thigh). This solution contributes to secure positioning and prevents slipping during use.Modular Arrangement of ChambersThe chambers or chamber modules with one or more chambers can be arranged both fixedly integrated and in a modular replaceable manner in the carrier material. This allows a high adaptability to individual requirements or specific inserts.Selective Placement in Exposed Body RegionsThe invention provides that the chambers can also be arranged in a targeted manner only in particularly endangered areas, e.g. armpits, shoulders, ledges or inner thighs. This variant enables optimization of the protection with reduced material use and weight.Pressure Controlled Material ReleaseThe device can be designed such that the hemostatic material escapes in a targeted reinforced manner when pressure is applied to the wound. In this case, the natural reflex of the injured person (e.g. pressing on the wound) is used to further optimize hemostasis.Material Engineering EmbodimentsThe chambers or substrate may be made of modern high performance materials including, for example:• elastic fabrics which contract upon perforation and control the discharge of hemostatic material,• Self-healing polymers which, after perforation, cause a partial closure,• Shape memory materials, e.g. wires or fibres made of nitinol, which specifically influence the size of the opening in response to temperature or pressure changes.These materials significantly improve the longevity, reliability and efficiency of the protection system.Pants and Helmet IntegrationThe invention can be implemented in further variants:• Pant Integration: The system is incorporated into a pant or pant-shaped undergarment to effectively protect the lower body regions.• Helmet integration: Chambers are integrated into a tactian helmet, which simultaneously performs the shock absorbing function. This results in a dual function of mechanical protection and medical emergency supply.Shock Attenuating Cushioning Materials and Modular AttachmentThe chambers may be made of a resilient shock absorbing plastic which provides additional protection against shocks. Furthermore, the chambers can be provided with a hook and loop tape or surface, whereby they can be detachably fastened to other carrier materials, vehicles or pieces of equipment, to which a corresponding fastening means, for example a hook and loop tape (e.g. with loops), is attached. This extends the field of application beyond the use on the body.Summary of the Overall Technical Contribution:The invention provides a highly innovative protection system intelligently combining emergency medical care with textile protection technology. The plurality of features described results in a protection system which responds not only autonomously to injuries, but also:• facilitates maintenance,• modular,• is based on most advanced developments in terms of material technology,• remains integratable into existing protective equipment,• smart functions such as sensor system and data transmission, and• Flexible can also be used in vehicles or on equipment parts.This comprehensive technical basis covers numerous deployment scenarios, ranging from military deployment to civil emergency situations.According to the invention, the device comprises a portable protective textile or a portable textile module containing a plurality of mutually separated, preferably dense, chambers.These chambers are preferably integrated into body zones which can bleed in a life-threatening manner in the event of injury caused by bombardment, for example in the last region, in the lower abdomen and upper abdomen, in the chest region, under the armpits, in the back region, in particular in the region of the kidneys, and in the neck and neck region. Or also in areas which are not covered by portable protective vests.The chambers can either be permanently integrated into a protective textile or can be designed as independent units which can be used in modular fashion and can be connected to the textile carrier without tools, for example by means of hook and loop fasteners, slide fasteners or textile insertion systems.Each chamber contains a hemostatically active material which, in a first embodiment, is in the form of a ready-to-use gel. This gel is preferably based on a combination of chitosan and kaolin and may optionally contain further additives, including antibacterial components such as silver ions, coagulation-promoting additives such as calcium compounds or bioactive substances such as curcumin or honey extracts.However, other hemostatic gels or liquids may also be used. The gel matrix is designed so that it causes a high viscosity, adhesion to tissue and temporary sealing of the wound when released.In an alternative embodiment, the chamber contains a dry gel-forming powder which hydrates to form a gel only upon contact with body fluid, in particular blood. This variant is distinguished by increased storage stability, lower weight and climatic robustness. The powder can contain, for example, micropulverized chitosan, dry kaolin, hydrophilic gelling agents such as carbopol or polyvinyl alcohol or absorbent nanofibers.Gel formation occurs within a few seconds of contact with liquid. By means of a capillary effect, the powder in the entire chamber changes into gel and can be expressed manually.In the normal state, the chambers are completely closed off. When mechanically perforated, for example by a projectile or a sharp object, the chambers open in a controlled manner and release the hemostatic material into the environment.As a result of the anatomical placement of the textile, the material reaches directly into the wound. The effect can be enhanced by additional pressure, for example by body weight, clothing or targeted manual compression.An advantageous further development of the invention provides that a plurality of chambers are preferably fluidically coupled to one another via microperforated connecting channels. These connections are designed such that, in the event of a pressure difference between two chambers, a passive gel flow, for example, can take place. Thus, when an intact chamber is loaded-for example because the wound lies on it-and simultaneously a pressure reduction in a chamber through which flow takes place, a material transfer is produced in the direction of the relieved chamber.This principle allows automatic, demand-based further delivery of active substance into injured areas without the need for active technology or control.A further aspect of the invention consists in the optional exchangeability of the chambers.The chambers can optionally be removed from the textile carrier without tools if necessary and filled up or replaced. This allows both removal before cleaning of the clothing and replacement after the end of the life or after medical use.The chambers can be marked optically or electronically (e.g. by means of RFID or QR identification) in order to monitor maintenance cycles and readiness for use.To additionally increase the capacity of use, each chamber can be provided with a manually activatable removal unit. This makes it possible to remove the hemostatic material in a targeted manner and thus also to supply other wounded goods which do not carry their own device.The removal device can be designed, for example, as a defined predetermined breaking point which can be opened with a pointed object, or as a hygienically closable outlet, for example in the form of a snap closure, a rotary membrane, a push-through opening or a tear-off valve.In an optional embodiment, the device is equipped with a sensor that detects a mechanical perforation. The sensor can be implemented, for example, as a resistance or strain sensor and activates an optical display unit, in particular an LED, in the case of a shot detection. Thus, an unnoticed wounding can also be detected. In addition, the device can have a wireless communication unit which, when activated, sends a signal to external medical devices or emergency control centers.Mode of action in connection with natural protective reflexesAn important technical advantage of the device according to the invention is that its function interacts in a targeted manner with the natural reflexes of humans. In penetrating injury, the human body responds instinctively with protective and destructive reactions which aim to shield the site of injury and to limit further damage. This includes, in particular, the reflex of holding the body location concerned or applying pressure thereto, for example by hand or by leaning the body against a fixed support.This intuitive action has several physiological principles: 1. pain modulation and pressure response.Mechanical stimuli, such as placing the hand on a wound, alleviate pain by attenuating the transmission of pain signals via known mechanisms of pain modulation in the central nervous system. This reflex therefore often leads to a sustained pressure on the wound, which not only provides subjective pain relief, but is also physiologically useful in reducing blood flow.2. Automatic Protection Reaction:In injury situations, the central nervous system triggers protective and defense reflexes which are anchored deep in the motor repertoire of humans. This includes automatic coverage or maintenance of the affected region - a behavior which is designed evolutionary to quickly control life threatening bleeding.3. Involute advantage of compression:From an evolutionary perspective, spontaneous application of pressure to a wound is a basic mechanism of behavior for damage limitation. This reflection is not only common in humans, but also in the animal kingdom and performs the function of a primary "first supply" until further measures can be initiated.4. Reaction under stress:In acute situations such as trauma, the combat or escape reaction is activated, preparing the organism for immediate damage limitation. A central feature of this reaction is the protection and stabilization of the injured site, which in practice is almost always associated with an involuntary application of pressure.These natural reflexes are used specifically by the device according to the invention in order to maximize the efficiency of hemostasis. In particular, the construction of the chambers and the hemostatic material is designed such that the wounder's pressure exerted instinctively:• the gel or powder exits the damaged chamber in a targeted manner,• directly depositing itself on the injured site and remaining adherent, and• Accelerating and enhancing hemostatic effect.The system therefore synergetically works with the natural reflexes of the body and does not require active engineering control or complex handling. A practical example is the utilization of its own body weight (e.g. by lying on the affected site), whereby the device is also activated and the escape of the material is promoted.The invention thus makes use of physiological and psychological protective reactions in an innovative manner to improve the medical initial care in the case of penetrating injuries. This represents a significant technical contribution since not only is a mechanical operating principle provided, but also a targeted integration of human behavior patterns takes place, which makes the protection system more effective.The invention is explained in more detail below with reference to exemplary embodiments and associated drawings.The following are shown: FIG. 1 shows protective clothing with several compartments, such as a vest, which can be closed in the crotch, FIG. 2 shows protective clothing with several compartments, such as a vest, which contain compartments only in desired areas, FIG. 3 shows protective clothing in the manner of a pants, FIG. 4 shows, for example, the embodiment of chambers which can be worn under a pants, FIG. 5 shows a tactian insert helmet with integrated chambers, FIG. 6 shows a tactian insert helmet with integrated chambers in an internal view,Description of Figure 1:FIG. 1 shows a preferred embodiment of the device according to the invention in the form of a portable protection system which is designed as a vest. In several areas of the vest positioned close to the body, chambers 1 are integrated which contain a hemostatically active gel. The arrangement and size of the chambers 1 are variable and can be adapted to different body sizes or anatomical conditions.The chambers 1 are embedded firmly in a lightweight, preferably net-shaped, carrier material 2 which serves as the basic structure of the item of clothing. At the upper end is the opening for the head of the carrier. Alternatively or additionally, the chambers 1 can be constructed in modular fashion, so that they can be removed from the carrier material 2 and exchanged if necessary.Flexible separating regions 3 are located between the individual chambers 1, serving to increase mobility and comfort for wearing. These separation regions 3 are designed in such a way that the chambers 1 remain arranged close to one another despite the flexibility and are likewise reliably activated in the case of a mechanical perforation in the region of the separation. In a further embodiment, adjacent chambers may be coupled together by connecting elements to enable a targeted transfer of the hemostatic gel upon pressure changes.The net-shaped carrier material 2 continues in the lower region of the device and forms either a crotch region 5 or a pant part which serves for the secure fixing of the vest to the body. This design ensures that the device rests stably on the body even in the case of intensive movements or in use under load.Technical EffectThe arrangement of the chambers 1 within a net-shaped carrier material 2 in combination with flexible separation regions 3 illustrated in FIG. 1 offers several technical advantages: 1. optimum mobility with simultaneous protection:The separation regions 3 increase the flexibility of the garment without interrupting the protection area. Despite the freedom of movement, the chambers 1 remain arranged close to one another, so that reliable activation of the hemostatic gel is ensured even in the region of the separating zones in the event of a penetrating injury.2. Targeted Material Release:Due to the possibility of connecting chambers to one another, a gel transfer can take place which assists the exit of the hemostatic material if necessary also across a plurality of chambers, in particular if a material flow is initiated by pressure conditions.3. Stability and Secure Positioning:The crotch or pant part 5 provided in the lower region ensures a secure fit of the device on the body. This ensures that the protective function is reliably maintained even during movement, physical load or longer wearing periods and the chambers always remain in the intended position.This combination of ergonomic design, modular construction and passive activation of the hemostatic system contributes substantially to the effectiveness of the device according to the invention, since it enables automatic, situation-adjusted hemostasis without the need for active measures by the user.Description of Figure 2:FIG. 2 shows a further embodiment of the protective apparel according to the invention in the form of a vest-like protective system, in which chambers are arranged in a targeted manner only in selected, particularly exposed regions.The net-shaped carrier material serves as a flexible base structure, in which the chambers 1 are integrated in defined protective zones. Unlike in the surface covering variant according to FIG. 1, the chambers 1 in this embodiment are positioned exclusively in particularly endangered body regions.In particular, chambers 1 are provided in the region of the armpits 6, since this region is considered a typical weak point and is covered only insufficiently in conventional protective vests. The arrangement of the chambers 1 in this region ensures a targeted protection of vital blood vessels.Further chambers 1 are located in the shoulder region 7, which are designed such that they can be carried without problems under conventional protective vests in order to additionally secure this particularly exposed region without restricting the freedom of movement.The net-shaped carrier material is preferably closely adjacent in the neck region 8, wherein this region can be supplemented with additional chambers if necessary in order to also provide an optional protective function here.In the region of the lower leg and the last region 11, chambers 1 are integrated which protect the body region lying below a conventional protective vest. The crotch part 10 not only reinforces the fixing of the device to the body, but can also be modularally equipped with further chambers 1 in order to ensure comprehensive protection down to the lower body region.Technical effect of the embodiment according to FIG. 2 :This selective arrangement of the chambers 1 in critical body zones offers several advantages: 1. increase of the protective effect with simultaneous reduction of weight and volume:By selective placement of the chambers 1 only at particularly injury-prone or difficult-to-protect locations, a high protective effect is achieved without significantly impairing the mobility or the wearing comfort.2. Combinability with existing protective equipment:The device is designed to be worn under or in combination with conventional protective vests, particularly in the shoulder area 7 and in the armpits 6, effectively compensating for typical weakness of classical protective apparel.3. Modularity and Flexibility:The neck region 8 which preferably bears closely together and the crotch / pant part allow expansion according to requirements with additional chambers 1, which enables individual adaptation to different hazardous scenarios.This embodiment thus provides an intelligent addition to existing protection systems, wherein in particular the vital vessel areas are secured by the automatic, pressure-dependent release of the hemostatic material.Description of Figure 3:FIG. 3 shows a further embodiment of the protective clothing according to the invention, in which the protective system is integrated into a tactian pants 13. This pants 13 have internal receptacles for hemostatic chambers 1, wherein a right chamber 1 and a left chamber 1 are provided, wherein the right chamber 1 on the right side covers the right last region 12, the inner thigh and the region up to the knee throat and the left chamber 1 on the left side covers the left last region 14, the inner thigh and the region up to the knee throat and can each be inserted separately from one another.The chambers 1 are arranged to selectively cover the last region, the inner thigh and the area beyond the knee throat. These areas are particularly sensitive to protection, since central arteries and veins run there, the injury of which can be life threatening without immediate hemostasis.The modular chambers can be inserted and replaced into the inner pockets of the pants as required. The freedom of movement is maintained by the discrete integration, while at the same time an effective protection against penetrating injuries in these critical body zones is ensured.Technical effect:This specific arrangement of the chambers 1 offers the following additional advantages: 1. expanded protection of central vessel regions:Covering the inguinal region, the inner thigh and the knee throat region ensures that injury in these heavily perfused areas results in immediate passive hemostasis by the leakage of hemostatic material.2. Protection of Movable Joint Portions:In particular, the area of the knee throat is difficult to secure in many protection systems, since it requires a high degree of flexibility. The solution according to the invention makes possible effective protection without restriction of mobility due to the modular and flexible design of the chambers.3. Tacticity:Modular integration allows emergency workers to individually adapt the protective equipment to the respective hazardous position, for example by targeted placement of the pants in risk-rich uses.Description of FIG. 4 :FIG. 4 shows a further embodiment of the device according to the invention, in which a net-shaped undergarment in the form of a pants 13 is provided. A right chamber 1 and a left chamber 1 are modular integrated into the regions 12 and 13 in this carrier material, as in FIG. 3This embodiment is specifically designed to be worn under a regular pants. The net-shaped carrier material, here in the manner of a pants 13, serves as a flexible base into which the chambers 1 can be inserted independently of the outer clothing.This offers the advantage that the protective function is ensured even when the outer pants-for example a standard or tactian pants-do not have integrated receptacles for chambers. The system can thus be worn universally in combination with any desired outer apparel.The chambers 1 in the areas 12, 14 are arranged in such a way that they cover the last region, the inner thigh as well as the area beyond the knee throat, analogous to the solution described in FIG. 3. The modular construction permits simple removal or replacement of the chambers, for example after activation or for maintenance purposes.Technical effect of the embodiment according to FIG. 4 :This variant offers in particular the following technical advantages: 1. independence of special outer clothing:Since the protection system is integrated into a stand-alone net-shaped undergarment (such as a pant 13), it can be flexibly worn under any pant 13. This increases the possible uses considerably, since no special adaptation to an external pants is required.2. Enhanced Utility and Comfort:The lightweight, breathable carrier material provides high wear comfort and allows an appreciable integration of the protective function into the everyday life or tactian inserts without the external appearance being changed.3. Modularity and Re-use:Due to the modular design of the chambers 1, the system can be quickly made ready for use or adapted to individual requirements, for example by retrofitting additional chambers 1 or replacing used elements.This embodiment significantly extends the flexibility of the protective apparel according to the invention and allows critical body regions to be protected even without specially adapted outer apparel.FIG. 5 : Description of the insert helmet in an external view with chambers integrated in an invisible mannerFIG. 5 shows an embodiment of the device according to the invention in the form of a tactian insert helmet 15 in an external view.The special configuration of this insert helmet 15 lies in the integration of several chambers, not shown here, which contain a hemostatically active material. These chambers are completely embedded in the inner structure of the insert helmet 15 and are not visible from the outside. The insert helmet 15 corresponds optically to a conventional tactian insert helmet 15 and does not have any externally recognizable changes or add-on modules.The chambers, which are not visible here, assume a dual function:• On the one hand, they serve as cushioning elements for shock absorption and for wearing comfort.• On the other hand, in the case of mechanical perforation, they allow the auto-release of hemostatic material for passive hemostasis in the case of head injuries.The discrete integration of the chambers protects them from external influences and at the same time ensures that the insert helmet 15 retains its classic protective effect.Technical effect of FIG. 5 :1. Discrete Medical Accessory Function:The chambers are integrated invisible, whereby the insert helmet 15 corresponds optically and functionally to a conventional model, but provides a life-saving additional function.2. Saving in space and weight:The combination of padding and medical protection function makes efficient use of the installation space.3. Critical Head Region Protection:The chambers are arranged such that they cover, in particular, forehead, temples, occipital areas and lateral head areas.4. Modularity:After activation, the chambers can be replaced without problems.FIG. 6 : Description of Tactian Insert Helmet with Integrated ChambersFIG. 6 shows an embodiment of the device according to the invention, in which a tactian insert helmet 15 is equipped with a plurality of integrated chambers 1. The illustration is made in an internal view.The chambers 16 are arranged inside the insert helmet 15 so that they perform several functions simultaneously: 1. cushioning effect:The chambers 1 are designed in such a way that they perform the classic cushioning and cushioning function, as is provided in conventional insert helmets 15 by separate cushioning elements. As a result, existing cushions can be completely or partially replaced, which leads to a weight reduction and more efficient use of space in the interior of the helmet.2. Medical Protection Function:In addition, the chambers 1 contain a hemostatically active material which is released in the case of mechanical perforation or in the case of direct action. In the event of penetrating injury to the head region, the material automatically escapes and assists immediate hemostasis without the need for active procedures by the wearer.The chambers 16 are preferably of modular construction and can be easily replaced after activation in order to make the insert helmet 15 ready for use again quickly.The chambers 1 are arranged in a targeted manner in particularly endangered head regions, such as forehead, temples, lateral head parts and back head, in order to ensure comprehensive protection of the most sensitive regions.Technical effect of FIG. 6 :The integration of the chambers 1 into the tactian insert helmet 15 offers the following essential technical advantages:• Dual functionality:The chambers 1 simultaneously perform the mechanical protection function (cushioning / shock absorption) and the medical emergency function (passive hemostasis). This reduces the space requirement and the weight of the insert helmet 15 compared to solutions with separate elements.• Immediate Response to Injury:When the helmet is perforated or in direct contact with the chambers 1, the hemostatic material is automatically released, thereby immediately supplying critical head injuries.• Maintenance of comfort and protection:The chambers are integrated in such a way that the wearing comfort and the external protective effect of the insert helmet 15 are not impaired. The modular construction allows rapid replacement of the chambers after use.• Optimized protection of critical head regions:The targeted positioning in areas susceptible to injury increases the safety, in particular in the case of tactical uses, military use or extreme sports.With the solution according to the invention, a garment is provided for the first time, which preferably contains a plurality of compartments 1 with hemostatically active material in a distributed manner, which are activated automatically upon mechanical perforation. Preferably, the reaction is passively reregulated, and pressure conditions are used. The chambers 1 can be bulk modular.Furthermore, instead of a chamber 1, a chamber module with several chambers 1 contained therein can be used.A chamber module can consist of one or more chambers in order to adapt to the anatomical circumstances.It is also possible for the chambers 1 to be opened for supplying third parties.Furthermore, an unnoticed penetration can optionally be detected sensorially.The chambers 1 or chamber modules filled with a hemostatic gel can consist of an elastic, but at the same time tear-resistant and mechanically stable plastic or a highly resistant film. This choice of material allows the chambers to also take over a shock-absorbing cushioning effect in addition to their function as a container for the hemostatic material. In particular in the case of falls or blunt actions of force, the risk of additional injuries can be reduced as a result.On the outer side of the chambers 1 or of the chamber modules facing away from the body, a hook-and-loop tape with barbs (adhesive part) can be attached over a large surface area. This allows the chambers or chamber modules to be detachably fastened also to various carrier materials or articles of clothing, for example to pants, shirts or back bags. For this purpose, a hook-and-loop tape with loops (fluff part) with a rear-side adhesive layer can be glued or sewn onto the respective clothing on the inner side. The chambers can thus be quickly attached and removed if necessary, without tools or special accessories. This modular fastening possibility also allows space-saving attachment of the chambers in vehicles, in particular in the vicinity of the driver's seat, on motor bicycles, boats or in armour-plated vehicles, in which wounding is to be expected at any time. The device can likewise be fastened in workplaces, workshops or medical stations in order to make possible an immediate supply of strong bleeding there in the event of a severity.In particular, the invention relates for the first time to a textile-integrated protection system having a plurality of modular or permanently integrated chambers which open automatically upon perforation and release a haemostatic material in the direction of the body.With the solution according to the invention, a passive supply of a penetrating injury to a person is possible, namely by the release of a hemostatically active material in gel or powder form from at least one chamber of a garment.For example, absorbable hemostatic particles in the form of spherical or ellipsoidal microporous microspheres may be employed. These should have good biocompatibility and can absorb and contain fluids such as blood by a multiple of their weight. Furthermore, a pressure is exerted on the peripheral vessel / vessels and, as a result, the bleeding is likewise stopped and hemostasis is promoted.With the solution according to the invention, a garment is provided for the first time, which preferably contains a plurality of chambers 1 or chamber modules with a plurality of chambers 1 with hemostatically active material, which are activated automatically upon mechanical perforation. Preferably, the reaction is passively reregulated, and pressure conditions are used. The chambers or chamber modules can also be modular. It is also possible for the chambers to be opened for supplying third parties. Furthermore, an unnoticed penetration can optionally be detected sensorially.Experience has shown that in the event of an injury, the human exerts intrinsic pressure on the affected site, whether by placing the hand or by specifically pressing the body against the wound. This natural reflex is advantageously utilized by the solution according to the invention, since the pressure exerted by the user causes the hemostatic gel contained in the chambers to emerge selectively and for the most part from the damaged chamber to the wound and can develop its haemostatic effect there.Engineering MaterialsModern materials can be used to implement the solution according to the invention, which specifically support the effects described:• Shape memory alloys (Shape Memory Alloys / Polymers)These materials have the property of deforming back to a predetermined original shape in the event of external stimuli such as temperature changes or electrical voltage. An example of this is nitinol, a nickel-titanium alloy, which contracts when the temperature rises. Such materials can help partially close openings after perforation or selectively control the exit of the hemostatic gel.• Elastic fabrics under tension:Prestressed elastic fabrics can ensure that, in the event of mechanical damage, the fabric contracts and the perforation location is thus reduced. This on the one hand assists the focusing of the gel outlet to the wound and on the other hand minimizes the undesired escape of the material.• Self-healing polymers:These materials are capable of producing a partial closure of the opening after perforation by molecular interactions. The use of such polymers can extend the functionality of the compartments and increase the stability of the garment.Practical ExampleA known example of the use of such material properties can be found in outdoor and sports textiles. In this case, what are known as "ripstop" fabrics are used, which prevent uncontrolled tearing of the fabric in the event of damage, in that the fabric fibers contract in a targeted manner. Even if these types of fabric do not completely close a perforation, they contribute to the delimiting of the opening and thus offer an additional protection mechanism which can be used advantageously within the scope of the present invention.Reference Character List1 Chambers or chamber modules 2 Mesh-shaped carrier material 3 Separation region 4 Opening for the neck 5 Crotch region 6 Region of the armpits 7 Shoulder region 8 Neck region 9 Abdominal region 10 Crotch part 11 Last region 12 Right chamber 13 Tactic pants 14 Left chamber 15 Tactic insert helmetReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
