Description

[0001] The present invention relates to a portable device in the form of a textile-integrated protective system according to the preamble of the first claim.

[0002] The invention is not limited to the features defined in the patent claims. Rather, further technical embodiments are described which are not claimed but are fully disclosed in order to provide alternative or supplementary embodiments.

[0003] The invention lies at the intersection of medical emergency equipment, personal protective equipment (PPE) and textile technology and is intended in particular for applications in military, governmental and civilian risk situations.

[0004] Hemostatic materials are known from the state of the 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.

[0005] For example, publication EP 1731175 B1 describes hemostatic cross-linked dextran beads used for rapid blood clotting and hemostasis. They can be administered via creams, lotions, and / or emulsions and may be contained in a matrix- or reservoir-type transdermal patch.

[0006] In publication EP 3 785 753 B1, a device for dispensing a hemostatic powder is disclosed, comprising an elongated hollow reservoir. A manual air pump is attached to the reservoir, and a discharge opening is located at the distal end of the reservoir. A porous filter is provided, which is slidably arranged in the reservoir between the air pump and the discharge opening. Furthermore, a spring is arranged in the reservoir between the air pump and the filter. The powder is located in the reservoir between the filter and the discharge opening, and the pump is in fluid communication with the discharge opening via the porous filter and the powder.

[0007] German patent application DE102016009877A1 discloses the structure of a "React Protect Package." A wound dressing is applied to the center of the package, and / or a cushion / spring padding is placed after the wound dressing to cushion the wound from pressure on sensitive and injured skin, absorb moisture (from the wound dressing), and better filter contaminated skin (from the wound dressing / filter layer). The barrier / insulating layer can be the next layer to protect the ingredients from the environment during application and to allow the ingredients to be absorbed until they dry and take effect on the open or irritated skin. Following this, the wound dressing / filling compartment can be inserted, containing the antiseptic, herbal cream mixture, and nitrogen, using the space puck or cannula-type filling / supply dressing compartment.The Space Puck can have three additional fine chambers that can release the antiseptic and / or the nitrogen and / or the herbal cream mixture. All ingredients, materials, and substances (components) mentioned in the React Protect Plaster can also be used variably, extensively, and combined in the React Protect Package.

[0008] A skin or wound dressing is also disclosed in German patent application DE 10 2017 125 281 A1. As its name suggests, it is applied to areas of the body that already have a wound. The device comprises an active ingredient and at least two chambers for storing at least two substances, which can be opened by mechanical means so that, after opening the chambers, the liquids are miscible and can be transferred into a carrier for the active ingredient.

[0009] Document EP 3 661 570 B1 also describes a wound dressing for treating a tissue lesion. This wound dressing comprises a first layer made of a fluid-impermeable material and at least partially fenestrated, and a second layer made of a fluid-impermeable material and at least partially fenestrated, wherein the second layer is coupled to the first layer to define a chamber between the first and second layers.and a third layer arranged within the chamber, the third layer comprising a distributor with a central region and a perimeter region, the perimeter region containing perforations arranged in a pattern defining a plurality of sub-regions of the perimeter region, the first layer and the second layer being detachably coupled to each other by a plurality of welds or bonds through the perimeter region of the third layer comprising the distributor near their outer edges.

[0010] These products therefore require manual application by medical personnel or first responders. Furthermore, concepts for smart textiles for controlled drug delivery or the integration of sensors have been explored, for example in the form of surgical dressings or reactive hydrogel textiles. However, these systems are not suitable for immediate hemostasis in cases of traumatic, penetrating injuries under mobile or tactical conditions.

[0011] In particular, the state of the art lacks a textile-integrated or modular system that can be effective over a large or the entire body area in the event of an injury.

[0012] The invention is based on the objective of providing a portable device that automatically releases a hemostatically active material upon penetrating injuries, thereby immediately treating the affected wound areas. The device should be fully or modularly integrable into textile structures, distributed over anatomically vulnerable body zones, enable passive pressure-differential-controlled drug redistribution, be maintenance-friendly and replaceable, and allow manual removal of the active ingredient for external application. Additionally, sensor-based penetration detection with optical or electronic feedback should be optionally integrated.

[0013] This problem is solved by the features of the first patent claim.

[0014] Advantageous embodiments result from the dependent claims.

[0015] According to the invention, a portable device in the form of a textile-integrated protective system for passive hemostasis in penetrating injuries is used, wherein the device has several chambers containing a hemostatically effective material which tear open upon mechanical perforation, so that the material from at least one chamber escapes into a wound. Internal tearability of the chambers

[0016] The chambers are designed so that they only open towards the inside of the garment, allowing for a directed release of the hemostatic material. Technically, this ensures that the material is delivered directly to the wound, minimizing losses and preventing uncontrolled leakage. This guarantees that the majority of the active ingredient remains where it is needed, significantly improving the effectiveness of hemostasis. Gel variant of the hemostatic material

[0017] The use of a pre-formed viscous gel offers the technical advantage of immediate hemostasis, as the gel adheres without delay, swells, and forms a temporary seal of the wound. This is particularly beneficial in cases of significant blood loss, as there is no waiting time for the material to activate. Furthermore, the gel formulation ensures that the material remains where it is released, as it cannot run off. Powder version of the hemostatic material

[0018] A dry, gel-forming powder offers the technical advantages of increased shelf life and improved climatic stability. The powder remains stable at high and low temperatures, is lighter than a gel, and only becomes active upon contact with blood. This improves its usability in extreme environments and simultaneously ensures that the hemostatic system functions reliably even during prolonged storage. Modularity and interchangeability of the chambers

[0019] The ability to replace the chambers modularly and without tools allows for cost-effective maintenance and a long service life for the protective system. This contributes to the system's sustainability, ensuring it is not designed as a disposable item. Furthermore, it increases operational flexibility, as chambers can be replaced or refilled on-site as needed. Microperforated connections for fluid flow

[0020] The connection of chambers via microperforated channels represents an innovative solution for the passive delivery of hemostatic material. By utilizing pressure differentials, the material can automatically flow from intact chambers into a damaged chamber. This increases safety and reliability, as the active ingredient can continue to flow into the injured area even after the initial release. Manual removal device

[0021] The manual dispensing device significantly expands functionality: In addition to self-sufficiency, the material can be selectively dispensed for the supply of third parties. This improves its applicability in both tactical and civilian settings. Defined openings such as snap closures, membrane closures, or tear-off valves ensure safe and hygienic dispensing. Sensors and display

[0022] The integration of a sensor for detecting chamber perforation represents a technological advancement over purely mechanical systems. Resistance or strain sensors allow the injury to be detected even if it is not immediately perceptible (e.g., in cases of numbness or during stressful situations). Combined with an optical display unit (e.g., LED) and wireless data transmission to a central control unit, this results in an intelligent system that immediately informs the emergency response team, thus accelerating medical care. Integration as a garment or arrangement within a garment

[0023] Designing the device as a garment, or integrating it within a garment, offers significant technical advantages. Textile integration positions the hemostatic system directly against the user's body, drastically reducing reaction time in an emergency. Unlike separately worn devices, this eliminates the risk of the device failing to function properly during an emergency.

[0024] The device is easy to handle. Furthermore, the textile embedding allows for discreet and comfortable wear, increasing acceptance in daily use – especially among safety-critical professions or in outdoor settings. Technically, this solution ensures that the protective function is always available "on the body," guaranteeing direct contact between the wound and the hemostatic material without the need for additional handling. This significantly optimizes functionality and reaction speed in the event of an injury.

[0025] Integrating the chambers into a garment with a crotch / trousers section, along with the implementation of flexible dividers, significantly improves ergonomics and comfort. The dividers allow for unrestricted movement without compromising the chambers' functionality. This ensures that the protective effect is maintained even during movement (e.g., running, squatting).

[0026] Further features of the solution according to the invention are described below: In addition to the claimed features according to claims 1 to 10, the invention includes further technical embodiments, which are described below by way of example. Flexible separation areas

[0027] The chambers can be connected by elastic or mesh-like separating zones, allowing for a particularly close fit to the body. This design helps ensure that the chambers remain stable even during intense movement, while simultaneously guaranteeing a high level of wearing comfort. The choice of materials in the separating zone ensures reliable activation of the hemostatic system. crotch area or trouser part

[0028] A crotch area or trouser section in the garment provides additional fixation and allows for the integration of further compartments to protect the lower body regions (e.g., groin, inner thigh). This solution contributes to secure positioning and prevents slippage during use. Modular arrangement of the chambers

[0029] The chambers or chamber modules, with one or more chambers, can be either permanently integrated or modularly interchangeable within the carrier material. This allows for a high degree of adaptability to individual requirements or specific applications. Selective arrangement in exposed body areas

[0030] The invention provides that the chambers can also be selectively arranged only in particularly vulnerable areas, e.g., armpits, shoulders, groin, or inner thighs. This variant allows for optimized protection with reduced material usage and weight. Pressure-controlled material release

[0031] The device can be designed so that the hemostatic material is released in a targeted manner when pressure is applied to the wound. This utilizes the injured person's natural reflex (e.g., pressing on the wound) to further optimize hemostasis. Material-related designs

[0032] The chambers or the support material can be made from modern high-performance materials, including, for example: • Elastic tissues that contract upon perforation and control the leakage of hemostatic material, • Self-healing polymers that bring about a partial closure after a perforation, • Shape memory materials, e.g. wires or fibers made of nitinol, which selectively influence the size of the opening in response to temperature or pressure changes.

[0033] These materials significantly improve the durability, reliability, and efficiency of the protection system. trouser and helmet integration

[0034] The invention can be implemented in further variations: • Trouser integration: The system is integrated into trousers or trouser-shaped undergarments to effectively protect the lower body regions. • Helmet integration: Chambers are integrated into a tactical helmet, which simultaneously provides shock absorption. This results in a dual function of mechanical protection and emergency medical care. Shock-absorbing padding materials and modular mounting

[0035] The chambers can be made of an elastic, shock-absorbing plastic that provides additional protection against impacts. Furthermore, the chambers can be equipped with a hook-and-loop fastener or patch, allowing them to be detachably attached to other materials, vehicles, or equipment that have a corresponding fastener, such as a hook-and-loop strip (e.g., with loops). This expands their range of applications beyond use on the body. Summary of the overall technical contribution:

[0036] The invention provides a highly innovative protective system that intelligently combines emergency medical care with textile protective technology. The multitude of described features results in a protective system that not only reacts autonomously to injuries, but also: • makes maintenance easier, • can be used modularly, • based on state-of-the-art material technologies, • can be integrated into existing protective equipment, • has smart features such as sensors and data transmission, and • can also be used flexibly in vehicles or on equipment parts.

[0037] This comprehensive technical base covers numerous operational scenarios, from military operations to civilian emergency situations.

[0038] According to the invention, the device comprises a portable protective textile or a portable textile module containing a plurality of separately arranged, preferably dense, chambers.

[0039] These chambers are preferably integrated into body areas that can bleed life-threateningly in the event of gunshot wounds, for example, in the groin, lower and upper abdomen, chest, under the armpits, back, especially around the kidneys, and neck. Or also in areas not covered by wearable body armor.

[0040] The chambers can either be permanently integrated into a protective textile or designed as independent, modular units that can be connected to the textile carrier without tools, for example by means of Velcro fasteners, zippers or textile insertion systems.

[0041] Each chamber contains a hemostatic material, which in a first embodiment is present as 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, anticoagulants such as calcium compounds, or bioactive substances such as curcumin or honey extracts.

[0042] Other hemostatic gels or liquids can also be used. The gel matrix is ​​designed to produce high viscosity, tissue adhesion, and temporary wound sealing upon release.

[0043] In an alternative embodiment, the chamber contains a dry, gel-forming powder that only hydrates into a gel upon contact with body fluid, particularly blood. This variant is characterized by increased storage stability, lower weight, and climatic robustness. The powder can, for example, contain micro-pulverized chitosan, dry kaolin, hydrophilic gelling agents such as carbopol or polyvinyl alcohol, or absorbent nanofibers.

[0044] The gel forms within seconds of contact with liquid. Through a capillary effect, the powder throughout the entire chamber transforms into a gel and can then be manually squeezed out.

[0045] Under normal conditions, the chambers are completely sealed. Upon mechanical perforation – for example, by a projectile or a sharp object – the chambers rupture in a controlled manner, releasing the hemostatic material into the surrounding area.

[0046] Due to the anatomical placement of the textile, the material is delivered directly into the wound. The effect can be enhanced by additional pressure, such as from body weight, clothing, or targeted manual compression.

[0047] An advantageous embodiment of the invention provides that several 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 occur. Thus, if an intact chamber is subjected to pressure—for instance, because the wounded person is lying on it—and a simultaneous pressure drop occurs in a perforated chamber, a material transfer towards the unloaded chamber is generated.

[0048] This principle allows for automatic, on-demand delivery of active ingredient to injured areas without the need for active technology or control.

[0049] Another aspect of the invention is the optional interchangeability of the chambers.

[0050] The chambers can be removed from the textile carrier without tools, refilled, or replaced as needed. This allows for removal before cleaning the clothing, as well as replacement after the expiration date or after medical use.

[0051] The chambers can be marked optically or electronically (e.g., using RFID or QR codes) to monitor maintenance cycles and operational readiness.

[0052] To further enhance operational capability, each chamber can be equipped with a manually activated dispensing unit. This allows for the targeted removal of hemostatic material, enabling the treatment of other wounded individuals who do not have their own device.

[0053] The dispensing device can, for example, be designed as a defined predetermined breaking point that can be opened with a pointed object, or as a hygienically sealable outlet, such as in the form of a snap closure, a rotary membrane, a push-through opening or a tear-off valve.

[0054] In an optional embodiment, the device is equipped with a sensor that detects mechanical perforation. The sensor can be implemented, for example, as a resistance or strain sensor and, in the event of a perforation detection, activates an optical indicator unit, in particular an LED. This allows even unnoticed injuries to be detected. Additionally, the device can have a wireless communication unit that, when activated, sends a signal to external medical devices or emergency control centers. Mechanism of action in connection with natural protective reflexes

[0055] A significant technical advantage of the device according to the invention lies in the fact that its function specifically interacts with natural human reflexes. In the case of a penetrating injury, the human body instinctively reacts with protective and defensive reactions aimed at shielding the injured area and limiting further damage. This includes, in particular, the reflex to hold the affected body part or to exert pressure on it, e.g., by the hand or by leaning the body against a firm surface.

[0056] This intuitive action has several physiological bases: 1. Pain modulation and pressure response: Mechanical stimuli, such as placing a hand on a wound, have a pain-relieving effect by weakening the transmission of pain signals via known mechanisms of pain modulation in the central nervous system. This reflex therefore often leads to sustained pressure on the wound, which not only provides subjective pain relief but is also physiologically useful in order to reduce blood flow. 2. Automatic protection response: In injury situations, the central nervous system triggers protective and Defensive reflexes are triggered, which are deeply rooted in the human motor repertoire. These include the automatic covering or holding of the affected area – a behavior that is evolutionarily designed to quickly control life-threatening bleeding. 3. Evolutionary advantage of compression: From an evolutionary perspective, the spontaneous application of pressure to a wound is a fundamental behavioral mechanism for damage control. This reflex is widespread not only in humans but also in the animal kingdom and fulfills the function of a primary "first aid" until further measures can be initiated. 4. Reaction under stress: In acute situations such as trauma, the fight-or-flight response is activated, preparing the organism for immediate damage control. A key feature of this reaction is the protection and stabilization of the injured area, which in practice almost always involves the unconscious application of pressure.

[0057] These natural reflexes are specifically utilized by the device according to the invention to maximize the efficiency of hemostasis. In particular, the design of the chambers and the hemostatic material is such that the instinctively exerted pressure of the wounded person: • the gel or powder escapes from the damaged chamber in a controlled manner, • adheres directly to the injured area and sticks to it, and • the hemostatic effect is accelerated and intensified.

[0058] The system therefore works synergistically with the body's natural protective reflexes and requires no active technical control or complex handling. A practical example is the use of one's own body weight (e.g., by lying on the affected area), which also activates the device and promotes the expulsion of the material.

[0059] The invention thus utilizes physiological and psychological protective reactions in an innovative way to improve initial medical care for penetrating injuries. This represents a significant technological contribution, as it not only provides a mechanical principle of action but also incorporates targeted integration of human behavioral patterns, making the protective system more effective.

[0060] The invention is explained in more detail below with reference to exemplary embodiments and associated drawings.

[0061] They show: Fig. 1 Protective clothing with multiple chambers in the form of a vest that can be closed at the crotch, Fig. 2 Protective clothing with multiple chambers in the form of a vest, containing chambers only in desired areas, Fig. 3 Protective clothing in the form of trousers, Fig. 4 For example, the design of chambers that can be worn under trousers, Fig. 5. A tactical helmet with integrated chambers, Fig. 6. A tactical helmet with integrated chambers, interior view, Description of Figure 1:

[0062] Fig. Figure 1 shows a preferred embodiment of the device according to the invention in the form of a wearable protective system designed as a vest. Chambers 1 containing a hemostatic gel are integrated into several areas of the vest positioned close to the body. The arrangement and size of the chambers 1 are variable and can be adapted to different body sizes or anatomical conditions.

[0063] The chambers 1 are firmly embedded in a lightweight, preferably mesh-like, support material 2, which serves as the basic structure of the garment. The opening for the wearer's head is located at the top. Alternatively or additionally, the chambers 1 can be modular, allowing them to be removed from the support material 2 and replaced as needed.

[0064] Flexible separating zones 3 are located between the individual chambers 1, serving to increase mobility and wearing comfort. These separating zones 3 are designed such that the chambers 1 remain closely spaced despite their flexibility and are reliably activated even in the event of a mechanical perforation in the area of ​​the separation. In a further embodiment, adjacent chambers can be coupled to one another by connecting elements to enable targeted transfer of the hemostatic gel in the event of pressure changes.

[0065] The mesh-like support material 2 continues into the lower part of the device and forms either a crotch area 5 or a trouser section, which serves to securely fix the vest to the body. This design ensures that the device remains stable against the body even during intense movements or when used under stress. Technical effect

[0066] The in Fig. The arrangement of chambers 1 within a mesh-like support material 2, as shown in the illustration, in combination with flexible separation areas 3, offers several technical advantages: 1. Optimal mobility with simultaneous protection: The separation zones 3 increase the garment's flexibility without compromising the protective area. Despite the freedom of movement, the chambers 1 remain closely spaced, ensuring reliable activation of the hemostatic gel even in the separation zones in the event of a penetrating injury. 2. Targeted material release: The ability to connect chambers to each other allows for gel transfer, which supports the release of hemostatic material across multiple chambers if needed, especially when pressure conditions initiate a material flow. 3. Stability and secure positioning: The crotch or trouser section 5, located in the lower area, ensures a secure fit of the device to the body. This guarantees that the protective function is reliably maintained even during movement, physical exertion, or prolonged wear, and that the chambers always remain in their intended position.

[0067] This combination of ergonomic design, modular construction and passive activation of the hemostatic system contributes significantly to the effectiveness of the device according to the invention, as it enables automatic, situation-adapted hemostasis without requiring active measures by the user. Description of Figure 2:

[0068] Fig. Figure 2 shows a further embodiment of the protective clothing according to the invention in the form of a vest-like protective system in which chambers are specifically arranged only in selected, particularly exposed areas.

[0069] The mesh-like support material serves as a flexible base structure into which the chambers 1 are integrated in defined protection zones. This differs from the area-wide variant according to... Fig. 1, in this embodiment, the chambers 1 are positioned exclusively in particularly vulnerable areas of the body.

[0070] In particular, chambers 1 are provided in the area of ​​the armpits 6, as this region is considered a typical weak point and is only inadequately covered by conventional protective vests. The arrangement of chambers 1 in this area ensures targeted protection of vital blood vessels.

[0071] Additional chambers 1 are located in the shoulder area 7. These are designed to be worn easily under conventional protective vests to provide additional protection to this particularly exposed area without restricting freedom of movement.

[0072] The mesh-like carrier material preferably lies close to the neck area 8, whereby this area can be supplemented with additional chambers if necessary to provide an optional protective function here as well.

[0073] In the lower abdomen and groin area 11, chambers 1 are integrated, which protect the body area below that of a conventional protective vest. The crotch / trouser section 10 not only reinforces the fixation of the device to the body, but can also be modularly equipped with further chambers 1 to ensure comprehensive protection down to the lower body. Technical effect of the embodiment according to Figure 2:

[0074] This targeted arrangement of chamber 1 in critical body zones offers several advantages: 1. Increased protective effect while simultaneously reducing weight and volume: By selectively placing chambers 1 only in areas that are particularly prone to injury or difficult to protect, a high level of protection is achieved without significantly impairing mobility or wearing comfort. 2. Compatibility 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, thus effectively compensating for typical weaknesses of classic protective clothing. 3. Modularity and flexibility: The preferably close-fitting neck area 8 and the crotch / trouser section allow for a needs-based extension with additional chambers 1, which enables individual adaptation to different hazard scenarios.

[0075] This embodiment thus offers an intelligent addition to existing protection systems, whereby in particular the vital vascular areas are protected by the automatic, pressure-dependent release of the hemostatic material. Description of Figure 3:

[0076] Fig. Figure 3 shows a further embodiment of the protective clothing according to the invention, in which the protective system is integrated into tactical trousers 13. These trousers 13 have internal recesses for hemostatic chambers 1, wherein a right chamber 1 and a left chamber 1 are provided, the right chamber 1 covering the right groin region 12, the inner thigh and the area extending beyond the popliteal fossa on the right side, and the left chamber 1 covering the left groin region 14, the inner thigh and the area extending beyond the popliteal fossa on the left side, and each chamber 1 can be used separately.

[0077] Chambers 1 are positioned to specifically cover the groin area, the inner thigh, and the area extending beyond the popliteal fossa. These areas are particularly vulnerable because they contain major arteries and veins, and injury to these can be life-threatening without immediate hemorrhage control.

[0078] The modular chambers can be inserted into and replaced as needed in the inner pockets of the trousers. This discreet integration preserves freedom of movement while simultaneously ensuring effective protection against penetrating injuries in these critical areas of the body. Technical effect:

[0079] This specific arrangement of chambers 1 offers the following additional advantages: 1. Enhanced protection of central vascular regions: Covering the groin area, inner thigh and popliteal region ensures that in the event of injuries in these highly vascularized areas, immediate passive hemostasis occurs through the release of the hemostatic material. 2. Protection of moving joint areas: The area behind the knee is particularly difficult to protect with many protective systems, as it requires a high degree of flexibility. The solution according to the invention, through the modular and flexible design of the chambers, enables effective protection without restricting movement. 3. Tactical adaptability: Modular integration allows emergency services to individually adapt the protective equipment to the respective hazard situation, e.g. by specifically equipping the trousers for high-risk operations. Description of Figure 4:

[0080] Fig. Figure 4 shows a further embodiment of the device according to the invention, in which a net-shaped undergarment in the form of trousers 13 is provided. A right chamber 1 and a left chamber 1 are modularly divided into sections 12 and 13 in this carrier material as in Figure 4. Fig. 3 integrated

[0081] This embodiment is specifically designed to be worn under regular trousers. The mesh-like support material, here resembling trousers 13, serves as a flexible base into which the chambers 1 can be inserted independently of the outer clothing.

[0082] This offers the advantage that the protective function is guaranteed even if the outer trousers – for example, standard or tactical trousers – do not have integrated pockets for pockets. The system can therefore be worn universally in combination with any outer garment.

[0083] Chambers 1 in areas 12 and 14 are arranged such that they – analogous to the one in Fig. The solution described in point 3 covers the groin area, the inner thigh, and the area extending beyond the popliteal fossa. The modular design allows for easy removal or replacement of the chambers, for example, after activation or for maintenance purposes. Technical effect of the embodiment according to Figure 4:

[0084] This variant offers the following technical advantages in particular: 1. Independence from special outerwear: Since the protective system is integrated into a self-contained, mesh-like undergarment (similar to trousers 13), it can be flexibly worn under any trousers 13. This significantly increases its range of applications, as no special adjustment to outer trousers is required. 2. Enhanced usability and comfort: The lightweight, breathable carrier material ensures a high level of wearing comfort and allows for discreet integration of the protective function into everyday life or tactical operations without altering the external appearance. 3. Modularity and reusability: The modular design of the chambers 1 allows the system to be quickly made ready for use or adapted to individual needs, for example by retrofitting additional chambers 1 or replacing worn elements.

[0085] This design significantly increases the flexibility of the protective clothing according to the invention and allows the protection of critical body areas even without specially adapted outerwear. Figure 5 - Description: Tactical helmet in external view with invisibly integrated chambers

[0086] Fig. Figure 5 shows an embodiment of the device according to the invention in the form of a tactical helmet 15 in an external view.

[0087] The unique design of this tactical helmet 15 lies in the integration of several chambers (not shown) containing a hemostatic material. These chambers are completely embedded within the helmet's internal structure and are not visible from the outside. Visually, the tactical helmet 15 is identical to a conventional tactical helmet 15 and exhibits no externally discernible modifications or additional modules.

[0088] The chambers, which are not visible here, serve a dual function: • On the one hand, they serve as cushioning elements for shock absorption and wearing comfort. • On the other hand, in the event of a mechanical perforation, they enable the automatic release of hemostatic material for passive hemostasis in head injuries.

[0089] The discreet integration of the chambers protects them from external influences while ensuring that the tactical helmet 15 retains its classic protective effect.

[0090] Technical effect of Fig. 5: 1. Discreet additional medical function: The chambers are invisibly integrated, meaning that the tactical helmet 15 visually and functionally corresponds to a conventional model, but provides a life-saving additional function. 2. Space and weight savings: The combination of padding and medical protective function allows for efficient use of the installation space. 3. Protection of critical head regions: The chambers are arranged in such a way that they cover, in particular, the forehead, temples, back of the head and sides of the head. 4. Modularity: Once activated, the chambers can be easily replaced. Figure 6 - Description: Tactical helmet with integrated chambers

[0091] Fig. Figure 6 shows an embodiment of the device according to the invention, in which a tactical helmet 15 is equipped with several integrated chambers 1. The illustration shows an internal view.

[0092] The chambers 16 are arranged inside the tactical helmet 15 in such a way that they perform several functions simultaneously: 1. Cushioning effect: The chambers 1 are designed to take over the classic damping and cushioning function, as provided in conventional operational helmets 15 by separate padding elements. This allows existing padding to be replaced completely or partially, resulting in weight reduction and more efficient use of space inside the helmet. 2. Medical protective function: Additionally, chamber 1 contains a hemostatic material that is released upon mechanical perforation or direct impact. In the event of a penetrating injury to the head area, the material is automatically released and aids in immediate hemostasis without requiring any active intervention from the wearer.

[0093] The chambers 16 are preferably modular in design and can be easily replaced after activation in order to quickly make the tactical helmet 15 ready for use again.

[0094] The arrangement of chambers 1 is specifically targeted in particularly vulnerable areas of the head, such as the forehead, temples, sides of the head and back of the head, to ensure comprehensive protection of the most sensitive regions. Technical effect of Figure 6:

[0095] The integration of chambers 1 into the tactical helmet 15 offers the following key technical advantages: • Dual functionality: Chamber 1 simultaneously fulfills the mechanical protection function (padding / shock absorption) and the medical emergency function (passive hemorrhage control). This reduces the space requirement and weight of the tactical helmet 15 compared to solutions with separate elements. • Immediate response in case of injury: In the event of a perforation of the tactical helmet or direct contact with chamber 1, the hemostatic material is automatically released, thereby providing immediate care for critical head injuries. • Maintaining comfort and protection: The chambers are integrated in such a way that the wearing comfort and the external protective effect of the tactical helmet 15 are not compromised. The modular design allows for quick replacement of the chambers after use. • Optimized protection of critical head regions: Targeted positioning in injury-prone areas increases safety, especially during tactical operations, military use, or Extreme sports.

[0096] The solution according to the invention provides, for the first time, a garment which preferably contains several chambers 1 distributed throughout, filled with hemostatic material, which are automatically activated upon mechanical perforation. Preferably, the garment reacts passively to pressure conditions. The chambers can also be modularly interchangeable.

[0097] Furthermore, instead of a single chamber 1, a chamber module containing several chambers 1 can be used.

[0098] A chamber module can consist of one or more chambers to adapt to the anatomical conditions.

[0099] It is still possible that chambers 1 can be opened to supply third parties.

[0100] Furthermore, an undetected penetration can optionally be detected by sensors.

[0101] The chambers or chamber modules filled with a hemostatic gel can be made of an elastic, yet tear-resistant and mechanically stable plastic or a highly resistant film. This choice of material allows the chambers to not only serve as containers for the hemostatic material but also to provide shock-absorbing cushioning. This can reduce the risk of further injuries, particularly in the event of falls or blunt force trauma.

[0102] A large hook-and-loop fastener (adhesive part) can be applied to the outer surface of chamber 1 or chamber modules, facing away from the body. This allows the chambers or chamber modules to be detachably attached to various materials or garments, such as trousers, shirts, or backpacks. For this purpose, a hook-and-loop fastener with loops (loop part) and an adhesive backing can be glued or sewn onto the inside of the garment. This allows the chambers to be quickly attached and removed as needed, without tools or special accessories. This modular attachment option also allows for space-saving installation of the chambers in vehicles, especially near the driver's seat, on motorcycles, boats, or in armored vehicles where injuries are a constant possibility.The device can also be installed in workrooms, workshops or medical stations to enable immediate treatment of severe bleeding in case of emergency.

[0103] In particular, the invention relates for the first time to a textile-integrated protective system with several modularly constructed or permanently integrated chambers that automatically open upon perforation and release a hemostatic material towards the body.

[0104] The solution according to the invention makes it possible to passively treat a penetrating injury of a person by releasing a hemostatically effective material in gel or powder form from at least one chamber of a garment.

[0105] For example, absorbable hemostatic particles in the form of spherical or ellipsoidal microporous microspheres can be used. These should exhibit good biocompatibility and be able to absorb and encapsulate fluids such as blood by several times their own weight. Furthermore, the coagulation mechanism is advantageously triggered, thereby accelerating natural blood clotting. Additionally, pressure is exerted on the peripheral vessels, which also stops bleeding and promotes hemostasis.

[0106] The solution according to the invention provides, for the first time, a garment that preferably contains several chambers 1 or chamber modules with multiple chambers 1 containing hemostatically active material, which are automatically activated upon mechanical perforation. Preferably, the garment reacts passively to pressure conditions. The chambers or chamber modules can also be modularly interchangeable. Furthermore, the chambers can be opened to provide care for third parties. Optionally, an undetected penetration can be detected by sensors.

[0107] In the event of an injury, people instinctively apply pressure to the affected area, either by placing their hand on it or by deliberately pressing their body against the wound. The solution according to the invention advantageously utilizes this natural reflex, as the pressure exerted by the user causes the hemostatic gel contained in the chambers to be released from the damaged chamber to the wound in a targeted and largely controlled manner, where it can exert its hemostatic effect. Technical materials

[0108] To implement the solution according to the invention, modern materials can be used which specifically support the described effects: • Shape memory materials (Shape Memory Alloys / Polymers): These materials have the property of returning to a predetermined original shape in response to external stimuli, such as temperature changes or electrical voltage. An example of this is nitinol, a nickel-titanium alloy that contracts when heated. Such materials can help to partially seal openings after a perforation or to control the flow of hemostatic gel. • Elastic fabrics under tension: Pre-tensioned elastic fabrics allow the tissue to contract upon mechanical damage, thus reducing the size of the perforation. This helps to focus the gel flow towards the wound and minimizes unwanted leakage of the material. • Self-healing polymers: These materials are able to partially close a perforated opening through molecular interactions. The use of such polymers can extend the functionality of the chambers and increase the garment's stability. Real-world example

[0109] A well-known example of the use of such material properties can be found in outdoor and sports textiles. These textiles utilize so-called "ripstop" fabrics, which, in the event of damage, prevent the uncontrolled tearing of the fabric by causing the fabric fibers to contract in a controlled manner. Even if these types of fabric do not completely close a perforation, they contribute to limiting the opening and thus offer an additional protective mechanism that can be advantageously used within the scope of the present invention.
