Description

Technical Field

[0001] The utility model relates to the technical field of emergency medical supplies, and more specifically to a hemostatic bandage. Background Art

[0002] With the acceleration of urbanization, accidental injuries caused by falls, falls, road traffic, transportation accidents and other situations are frequent, and the need to stop bleeding from wounds is increasing. At present, first aid to stop bleeding usually uses a tourniquet or a conventional bandage. The use of a tourniquet to apply pressure to stop bleeding is quick and simple to operate, but its pressure is unstable, the force-bearing area is small, the time required to stop bleeding is long, the wound heals slowly and may cause adverse reactions. For wounds close to the proximal end of the limbs, such as the neck, groin or pelvis, it is difficult to form good pressure on the wound with a tourniquet, and manual pressure is required to assist in stopping bleeding.

[0003] Using conventional bandages for bandaging takes a long time. When applied to head trauma, it has the disadvantages of being easy to fall off and being unable to apply local pressure. When applied to wounds at large joints of the limbs, it is inconvenient to unwrap the wound repeatedly, and long-term bandaging can easily lead to blood circulation disorders in the affected limbs. When applied to waist and abdominal trauma, since the wound is often deep and the space is large, this area lacks the support and protection of the bone structure, and the bandage is difficult to achieve a good compression and hemostasis effect. Utility Model Content

[0004] The purpose of the utility model is to provide a hemostatic bandage that can bandage wounds in multiple parts of the human body stably and form a good compression and hemostasis effect on wounds in multiple parts, in view of the problem that tourniquets or conventional bandages in the related art are difficult to bandage wounds in multiple parts of the human body and there is also a problem that it is difficult to form effective compression and hemostasis for wounds in some parts.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A hemostatic bandage comprises: a main body, which is provided with an air chamber and an air port connected to the air chamber to control the expansion volume of the main body, along the length direction of the main body, one end of the main body is provided with a first connecting part, and the other end of the main body is provided with a second connecting part, and the first connecting part and the second connecting part can be connected and fixed to each other; a strap, one end of which is fixed to one end of the main body close to the first connecting part, and the other end can be fixed to the second connecting part; a tablet fixed to the main body for covering a wound.

[0007] Through the design of the air chamber, after the hemostatic bandage is simply wound around the wound, it can form a good tight compression on the wound based on inflation pressure, avoiding the need to wind multiple circles like a conventional bandage to achieve the corresponding dressing tightness. At the same time, by operating the air inlet and outlet for inflation and deflation, it is easy to flexibly adjust the dressing tightness, facilitating the avoidance of the problem of long-term ischemia of the limbs and improving the dressing comfort of the patient;

[0008] Combined with the design of the strap, the hemostatic bandage can well accommodate wounds on multiple parts of the human body. That is, the length of the body can be designed to fit parts with a smaller dressing circumference such as the head, neck or limbs. When dressing, the body does not need to be repeatedly wound around, avoiding the formation of a multi-loop structure that is prone to slipping, ensuring the stability of dressing these parts. At this time, the strap can be used to further wind the body, thereby strengthening the stability of the body dressing; when dressing parts with a larger dressing circumference such as the waist, abdomen or groin, the length of the body only needs to cover the wound area, and the corresponding extension effect of the strap is used to form a complete surrounding dressing.

[0009] The hemostatic bandage provided by the present utility model, through the combined design of the air chamber of the body and the strap, can accommodate wounds on multiple parts of the human body for dressing, and can form a stable dressing structure and achieve a good hemostatic effect on the wound. Compared with the existing tourniquets or conventional bandages, the hemostatic bandage has a larger scope of application and a better hemostatic effect. Especially for parts prone to bleeding such as the head, neck, large joints of the limbs, waist and abdomen, it can be used in a universal manner, and the practicability is significantly improved.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0039] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0040] Embodiment

[0041] As Figures 1-11 shown, a hemostatic bandage 100 of the present utility model includes: a main body 110, which is provided with an air chamber inside and is provided with an air port 111 communicating with the air chamber to control the expansion volume of the main body 110. Along the length direction of the main body 110, one end of the main body 110 is provided with a first connection part 112, and the other end of the main body 110 is provided with a second connection part 113. The first connection part 112 and the second connection part 113 can be connected and fixed to each other; a binding band 120, one end of which is fixed to one end of the main body 110 close to the first connection part 112, and the other end of which can be fixed to the second connection part 113; and a tablet 130, which is fixed to the main body 110 and is used to cover the wound.

[0042] The main body 110, as the main structure for the hemostatic bandage 100 to bandage the wound, through the cooperation of the first connection part 112 and the second connection part 113, the main body 110 itself can achieve the bandaging effect by surrounding one circle. The binding band 120, as an extension of the main body 110, can also be connected and fixed to the second connection part 113, and then can jointly form a larger loop structure with the main body 110 for bandaging.

[0043] Through the design of the air chamber, after the hemostatic bandage 100 is simply wound around the wound, it can form a good and tight compression on the wound based on its own expansion and pressurization, which can avoid the need to wind multiple circles like a conventional bandage to achieve the corresponding bandaging tightness. At the same time, by operating the air port 111 for inflation and deflation, it is easy to flexibly adjust the bandaging tightness, which is convenient for avoiding the problem of long-term ischemia of the limbs and can also improve the bandaging comfort of the patient;

[0044] Combined with the design of the strap 120, the hemostatic bandage 100 can well accommodate wounds on multiple parts of the human body. That is, the length of the main body 110 can be designed to fit parts with a smaller bandaging circumference, such as the head, neck, or limbs. When bandaging, the main body 110 does not need to be repeatedly wound around, avoiding the formation of a multi-loop structure that is prone to slipping, ensuring the stability of bandaging these parts. At this time, the strap 120 can be used to further wind around the main body 110, thereby strengthening the stability of the main body 110 during bandaging. When it is necessary to bandage parts with a larger bandaging circumference, such as the waist, abdomen, or groin, the length of the main body 110 only needs to cover the wound area, and the corresponding extended effect of the strap 120 is used to form a complete surrounding bandage.

[0045] For the hemostatic bandage 100 of the present utility model, through the combined design of the air chamber of the main body 110 and the strap 120, it can accommodate wounds on multiple parts of the human body for bandaging, and can form a stable bandaging structure and achieve a good hemostatic effect by compressing the wound. Compared with existing tourniquets or conventional bandages, the hemostatic bandage 100 has a larger scope of application and a better hemostatic effect. In particular, it can be commonly used for easily bleeding parts such as the head, neck, large joints of the limbs, waist, and abdomen, and the practicability is significantly improved.

[0046] In some alternative embodiments, the main body includes a pressing area and a wrapping area arranged side by side, and both the pressing area and the wrapping area extend along the length direction of the main body, and the air chamber is located in the pressing area.

[0047] The design of the pressing area and the wrapping area extending along the length direction of the main body 110 enables the hemostatic bandage 100 to be flexibly turned upside down for bandaging during first aid, thereby forming different pressurization methods to better adapt to different bleeding conditions and improve the hemostatic effect of the hemostatic bandage 100. For example, if the wound is arterial bleeding in the leg, when using the hemostatic bandage 100 for bandaging, the pressing area can be selected to be located above the leg, and the air chamber is inflated for pressurization, while the wrapping area located below the leg forms a binding state, thereby forming different pressure differences on both sides of the wound, making the compressive force at the proximal end of the wound significantly greater than that at the distal end of the wound, so as to achieve a reasonable hemostatic effect on the wound specifically. Similarly, for example, if the leg is venous bleeding, only the pressing area is selected to be located below the leg, and the air chamber is inflated for pressurization, so that sufficient compressive force can be formed at the distal end of the wound, achieving a good hemostatic effect on the wound, and avoiding simultaneous pressurization on both ends of the wound, causing unnecessary regional compression to the patient.

[0048] When manufacturing the hemostatic bandage 100 product including a pressing area and a wrapping area, in order to enable patients to accurately distinguish between arterial bleeding and venous bleeding for bandaging, on the outer package of the product, it can be clearly marked in prominent font and color: "The blood at the wound is dark red, place the pressing area at the distal end; the blood at the wound is bright red, place the pressing area at the proximal end", that is, when a vein is injured and bleeding, the side of the wound away from the heart corresponds to the pressing area of the hemostatic bandage 100, and when an artery is injured and bleeding, the side of the wound close to the heart corresponds to the pressing area of the hemostatic bandage 100.

[0049] In some alternative embodiments, the body 110 is provided with two air chambers side by side, and the two air chambers extend along the length direction of the body 110, and each air chamber has a corresponding air port 111 communicated therewith.

[0050] Design two air chambers extending along the length direction of the body 110, so that the hemostatic bandage 100 can be inflated and expanded selectively during first aid use, thereby forming different pressurization methods to better adapt to different bleeding conditions and improve the hemostatic effect of the hemostatic bandage 100. For example, if the wound is arterial bleeding in the leg, then when using the hemostatic bandage 100 for bandaging, only the air chamber located above the leg can be selected for inflation and pressurization, and the air chamber located below the leg does not need to be inflated or is inflated slightly, so that the bandage body 110 below the leg forms an appropriate bundling state, and then different pressure differences are formed on both sides of the wound to achieve a reasonable wound pressing effect. Similarly, for example, if the leg is venous bleeding, only the air chamber located below the leg can be selected for inflation and pressurization.

[0051] In some alternative embodiments, the first connecting portion 112 and the second connecting portion 113 adopt a Velcro connection method, and the strap 120 and the second connecting portion 113 also adopt a Velcro connection method.

[0052] The connection methods of the first connecting portion 112 and the second connecting portion 113, and the connection method of the strap 120 and the second connecting portion 113 can be various, such as the method of pressing buttons, the method of button threading through holes, the method of hanging rings and buckles, etc. Further preferably, it is the bonding method of Velcro, which not only has simple connection and fixing operations, but also has a large range of connection options, is easy to adjust the size of the loop formed by bandaging, and can be adapted to more human body parts for bandaging.

[0053] In some alternative embodiments, the back surface of the tablet 130 is detachably fixed to the body 110, and the front surface of the tablet 130 is coated with a traditional Chinese medicine dressing in which the total iridoid glycoside active component in Lamiophlomis rotata and medical activated carbon fibers are organically combined.

[0054] The tablet 130 and the main body 110 can be fixedly connected in a detachable manner. For example, a magic tape can be used to form a paste connection. The detachable design facilitates the replacement of tablets 130 of different sizes for wounds of different areas, further improving the scope of application of the hemostatic bandage 100 and ensuring the hemostatic effect.

[0055] The traditional Chinese medicine dressing coated on the tablet 130 can exert the synergistic effects of the two components, having beneficial effects on the wound such as hemostasis, promoting wound healing, having few adverse reactions, and not causing thermal damage, providing a safer and more natural hemostasis method and enhancing the safety of first aid.

[0056] In some alternative embodiments, an airbag 140 is further provided between the main body 110 and the tablet 130. The back surface of the airbag 140 is detachably fixed to the main body 110, and the front surface of the airbag 140 is detachably fixed to the tablet 130.

[0057] The main body 110 is equipped with an airbag 140 in the area of the tablet 130. Thus, the airbag 140 with an expandable volume can form local pressure on the wound. Compared with the overall pressure applied by the main body 110 to the entire dressing area, the local pressure applied by the airbag 140 is more targeted. Cooperating with the pressure applied by the main body 110, it can further improve the hemostatic performance of the hemostatic bandage 100, enhance the applicability to various types of wounds, and is especially suitable for wound areas lacking bony structure support such as the waist and abdomen.

[0058] In some alternative embodiments, the airbag 140 is a rectangular structural member and is provided with an air nozzle 141 for controlling the expandable volume of the airbag 140.

[0059] Compared with circular or irregular airbags 140, the rectangular airbag 140 has the characteristics of large contact area, firm adhesion, uniform pressure distribution, not easy to displace, and simple production. The design of the air nozzle 141 enables the adjustable expandable volume of the airbag 140, facilitating the flexible adjustment of the local compression force of the airbag 140.

[0060] In some alternative embodiments, the main body 110 is a rectangular structural member or a semi-circular structural member.

[0061] When the main body 110 is a rectangular structure, it is easy to process, has a regular shape after dressing, and the dressing operation is simple and reliable. When the main body 110 is a semi-circular structure, when performing circumferential dressing, if the two paste-fixing ends of the main body 110 are horizontally aligned, the formed dressing structure has the characteristic of being narrower at the top and wider at the bottom, which is especially suitable for firmly dressing the head or the root of the thigh area. If a dressing structure with a comparable upper and lower perimeter is required, the semi-circular main body 110 can also be achieved by the misaligned docking of the two paste-fixing ends, further improving the versatility of the hemostatic bandage 100 and the dressing stability of some parts.

[0062] In some alternative embodiments, along the width direction of the main body 110, a head net 150 is detachably connected to one side of the main body 110, and a fixing strap 160 is detachably connected to the other opposite side of the main body 110. The head net 150 is used to cover the skull, and the fixing strap 160 is used to press against the mandible.

[0063] The mutual cooperation of the head net 150 and the fixing strap 160 is used to prevent the hemostatic bandage 100 for head dressing from falling off, which can further strengthen the stability of the hemostatic bandage 100 for dressing the head wound, and at the same time avoid compressing the facial artery and thus affecting the blood supply of the face.

[0064] In some alternative embodiments, the head net 150 includes a plurality of intersecting cord bands. Buckles 170 are connected to both ends of the cord bands, and the main body 110 is provided with mounting holes 114 adapted to the buckles 170.

[0065] The head net 150 is formed by the intersecting cord bands, which has a simple structure and is easy to carry. And in cooperation with the buckles 170, it can quickly form a connection relationship with the mounting holes 114 of the main body 110, is convenient for disassembly and assembly, and has strong practicability.

[0066] In some alternative embodiments, the length of the main body 110 is 45 - 55 cm, and the length of the strap 120 is 20 - 50 cm.

[0067] Both the main body 110 and the strap 120 are strip-shaped structural members. The length range of the main body 110 can be suitable for the circumferential dressing of the necks, heads and large joints of the limbs of most human bodies. As an extension of the main body 110, the selection of the length range of the strap 120 enables the hemostatic bandage 100 to be effectively suitable for the dressing of most human trunk parts, such as circumferentially dressing the wounds on the waist and abdomen.

[0068] In some alternative embodiments, a hook and loop 180 is provided at one end of the main body 110 close to the second connection portion 113. The hook and loop 180 is used for reverse dressing of the main body 110 or the strap 120.

[0069] Reverse dressing means that the first connection portion 112 of the main body 110 or the strap 120 can pass through the hook and loop 180 in a certain direction to form a surrounding structure required for dressing, and then surround and fix it to the second connection portion 113 of the main body 110 in the opposite direction. Through the design of the hook and loop 180, the first connection portion 112 can be on the same side of the main body 110 as the second connection portion 113, so as to form a surrounding fixation, avoiding the first connection portion 112 or the second connection portion 113 being on the side of the main body 110 in contact with the human body, improving the use experience of the hemostatic bandage 100, and at the same time increasing the maximum coverage range of the tablet 130.

[0070] In some alternative embodiments, an air inlet 111 is connected to an air pumping device 190, and the air pumping device 190 includes an air pumping balloon 191 and an inflation nozzle 192.

[0071] The air pumping device 190 is a simple manual device, which is light and easy to carry. Through the cooperation of the air pumping balloon 191 and the inflation nozzle 192, it is convenient to inflate and deflate the main body 110. Repeatedly squeezing the air pumping balloon 191 can control the main body 110 to gradually increase in volume, and opening the inflation nozzle 192 can release the pressure in the air chamber to control the main body 110 to decrease in volume.

[0072] In some alternative embodiments, the air pumping device 190 further includes a pressure detection gauge 193, which is used to monitor the pressure in the air chamber so as to control the inflation degree of the main body 110 in real time, further improving the safety of product use.

[0073] In some alternative embodiments, a sterile pad is pasted on the side of the fixing tablet 130 of the main body 110. The sterile pad can be detachably fixed to the main body 110 through a magic tape, and the sterile pad is provided with an avoidance hole to expose the tablet 130, thereby forming a disposable replacement component, which can be replaced for different patients, improving the hygiene of the hemostatic bandage 100.

[0074] In some alternative embodiments, the main body 110 is made of soft fabric and vinyl.

[0075] Based on the material selection of the main body 110, the air chamber can be directly formed by the hollow structure of the main body 110, that is, the main body 110 is a single-layer structure, or it can be formed by embedding an inner capsule layer in the hollow structure of the main body 110, that is, the main body 110 is a double-layer structure. Further preferably, the main body 110 is composed of two materials, soft fabric and vinyl, that is, a double-layer structure is selected to form the air chamber, which can have appropriate elasticity and skin-friendly properties, be environmentally friendly, non-toxic, odorless, soft, reusable, and easy to disinfect, improving the practicality of the product.

[0076] Based on the convenience of production and processing and the requirements of specific working conditions, certain selections and combinations are made among various alternative embodiments. Specifically, soft fabric and vinyl are used as the constituent materials of the main body 110, which have certain elasticity and good sealing performance. As Figure 1 and Figure 2 shown, the main body 110 is a rectangular strip with a length of 52 cm and a width of 15 cm, and the main body 110 is a hollow structure with an air chamber formed inside. An air inlet 111 communicating with the internal air chamber is also provided on the back of the main body 110. The air inlet 111 is connected to an air pumping device 1.90 through a trachea. The air pumping device 190 includes an air pumping balloon 191, an inflation nozzle 192, and a pressure detection gauge 193.

[0077] As Figure 1As shown in the figure, on the back of the main body 110, the first connecting part 112 and the second connecting part 113 are respectively provided at the left and right ends of the main body 110. The first connecting part 112 is the hook surface of the Velcro, and the second connecting part 113 is the loop surface of the Velcro.

[0078] At the head end of the main body 110 close to the first connecting part 112, a strap 120 with a length of 45 cm is fixed to the main body 110. The end of the strap 120 is provided with the hook surface of the Velcro. At the end of the main body 110 close to the second connecting part 113, a hook-and-loop 180 is fixed to the main body 110 for the first connecting part 112 or the strap 120 to pass through and then be reversely pasted to the second connecting part 113.

[0079] As Figure 2 shown in the figure, a tablet 130 is pasted on the front of the main body 110. The main body 110 has the loop surface of the Velcro, and the area of the loop surface can be flexibly set. The back of the tablet 130 is the hook surface of the Velcro. The front of the tablet 1.30 is coated with a traditional Chinese medicine dressing in which the total iridoid glycoside active component in Duyiwei and medical activated carbon fibers are organically combined. The material of the tablet 130 can be a sterile cotton sheet, which can be vacuum-packed alone after high-pressure sterilization and disassembled and pasted onto the main body 110 only when in use.

[0080] As Figure 3 shown in the figure, on the loop surface on the front of the main body 110, an airbag 140 can also be installed between the main body 110 and the tablet 1.30. The airbag 140 is a rectangular hollow bag. As Figure 4 shown in the figure, the back of the airbag 140 has an adhesive surface 142, which is the hook surface of the Velcro, so as to be easily pasted onto the loop surface on the front of the main body 110. The expansion volume of the airbag 140 can be a fixed value made at the factory. Multiple airbags 140 with different expansion volumes can be prepared for direct selection on-site, improving the dressing efficiency and reducing the operation time. An air nozzle 141 can also be opened on the back of the airbag 140. The air nozzle 141 can be separately connected to a set of inflation devices 190 through a trachea, so as to easily control the occupied space of the airbag 140 and facilitate carrying. As Figure 5 shown in the figure, the front of the airbag 140 has an adhesive surface 143, which is the loop surface of the Velcro, so as to be easily pasted with tablets 130 of different sizes.

[0081] As Figure 6 shown in the figure, a plurality of mounting holes 114 can be opened on the longer side of the main body 110. Furthermore, a head net 150 and a fixing strap 160 can be installed on the main body 110. The head net 150 can be composed of six cord straps intersecting each other, and the fixing strap 160 can also be composed of a cord strap with an adjustable length. As Figure 7As shown, the cord is made of nylon rope, and buckle rings 170 can be fixed at both ends of the nylon rope. The head net 150 and the fixing band 160 are both detachably connected to the main body 110 by snapping the buckle rings 170 into the mounting holes 114. In addition, the head net 150 can also be made of other elastic materials. To improve the wearing comfort, multiple relatively wide cords can be further used to cross-compose the head net 150, or a fine mesh cap structure can be directly formed by elastic cords. The edges around the head net 150 are all connected to the mounting holes 114 through the buckle rings 170. When it is necessary to bandage a head wound, the addition of the head net 150 and the fixing band 160 can further improve the bandaging stability of the hemostatic bandage 100.

[0082] Through the adhesion of the first connecting portion 112 and the second connecting portion 113, the main body 110 forms a ring structure that can be widely applied to bandage parts of the human body such as the head, neck, and thigh joints. When applied to a neck wound, since the nerves and blood vessels in this area are dense, when bandaging, the main body 110 does not need to be inflated, but an air bag 140 can be added at the wound for local pressing, which can avoid compression and damage to the blood vessels and nerves outside the wound area.

[0083] The extended length of the strap 120 can cooperate with the main body 110 to bandage most parts of the human body such as the waist, abdomen, or groin. When applied to a waist and abdomen wound, not only can an air bag 140 be added to form a more stable and effective hemostatic compression, but it can also be used in conjunction with a tension reducer. Place the traditional Chinese medicine dressing on the surface of the wound, and then stick the tension reducer on the surrounding skin surface for use, which helps to close the abdominal wall defect and avoid peritoneal recovery caused by abdominal cavity infection and continuous opening of the abdominal wall defect.

[0084] In some embodiments, the main body 110 can also adopt a double-row truncated seam process, where two rows of stitches are compacted in the middle part along the length direction of the main body 110, dividing the main body into a pressing area and a wrapping area. The air chamber is only arranged in the pressing area. Thus, when bandaging, the pressing area and the wrapping area can respectively adapt to the proximal end area and the distal end area of the wound, forming targeted unilateral pressing of the wound, making the wound compression more scientific and reasonable.

[0085] In addition, as Figure 8 shown, two independent air chambers can also be respectively set for the pressing area and the wrapping area of the main body 110. Air ports 111 are opened on the upper and lower sides of the main body 110, and the two air ports 111 respectively correspond to and communicate with the upper and lower air chambers, and both of the two air ports 111 are respectively connected with an inflation device 190.

[0086] In some embodiments, the main body 110 can also be designed as a semi-circular structure, as Figure 9As shown, the upper and lower sides of the body 110 are arc-shaped, and the length of the lower side is greater than that of the upper side. Other connecting structures such as the strap 120, the first connecting portion 112, and the air inlet 111 are similar to the rectangular hemostatic bandage 100. In this way, when bandaging, the pasting method can be flexibly selected to adapt to different wound sites, and thus a more reliable bandaging effect can be achieved for some sites. For example, when used for head bandaging, as Figure 10 shown, the two ends of the body 110 can be aligned with each other and wound to form a ring structure that is narrow at the top and wide at the bottom and adapts to the size of the head. If used for waist bandaging, as Figure 11 shown, the two ends of the body 110 can be pasted in a staggered manner to form a ring structure with equal upper and lower parts.

[0087] During use, in order to improve the hygiene of the hemostatic bandage 100, the circular plush surface exposed on the front of the body 110, that is, the area not covered by the tablet 130 or the airbag 140, can be fully utilized. An aseptic pad with a barbed surface can be pasted for isolation. The size of the aseptic pad is equivalent to that of the body 110, and corresponding avoidance holes are designed according to the sizes of the tablet 130 or the airbag 140, and can be replaced for different patients.

[0088] The hemostatic bandage 100 provided by the present utility model can provide a certain pressure while stopping bleeding, effectively prevent the bleeding opening from rupturing again, enhance the hemostatic effect, and at the same time promote blood coagulation by using traditional Chinese medicine ingredients to reduce bleeding. This rapid and effective hemostatic method can meet the first-aid hemostasis needs in special environments and is of great significance for rescue; it can take into account the wounds of multiple parts of the human body for bandaging, and the general-purpose portable setting can be applied to a variety of first-aid scenarios, such as in outdoor sports, traffic accidents or other emergencies, with a wide audience; finally, it expands the application field of traditional Chinese medicine, solves some deficiencies of the existing first-aid methods, especially in terms of bleeding control, and also improves the self-help and mutual rescue capabilities of individuals in emergency situations.
