Description

1 TARIFF A HEMOSTATIC TOURNIQUET Technical Area This invention is suitable for conflict zones, terrorist attacks, military operations, and natural disasters. In high-risk and resource-constrained situations like these, rapid and effective responses to injuries are crucial. Tactical medicine, a field aimed at effective intervention, and casualty care in tactical warfare. Under the Protocol (TCCC); and also for civilian use, traumatic injuries serious complications that occur afterwards, especially in extremities such as arms or legs. 10 with an improvement to the tourniquet structure used to stop bleeding It is related. State of the art Tactical medicine, military operations, conflict zones, terrorist attacks, and natural disasters 15 in high-risk, disorderly, and resource-limited environments, traumatic It is a specialized medical discipline aimed at providing rapid and effective treatment for injuries. The main purpose of the discipline is to identify individuals, usually non-health personnel, at the scene of an incident. The initial intervention performed by [the doctor] brought the life-threatening bleeding under control. taking, securing the airway and maintaining vital functions 20 It is to be supported. In this context, the widely implemented Tactical Warfare Casualty Care system was developed. The protocol (TCCC - Tactical Combat Casualty Care) is particularly relevant in the battlefield or Extremity bleeding occurring in tactical conditions is rapidly treated within 25 days. It prioritizes bringing the situation under control. A significant portion of the deaths in the field... part of it, which, if left untreated, can result in death within minutes. It results from arterial bleeding. Therefore, the injection applied to the extremity... An effective tourniquet device is a critical factor that directly affects survival rates. It is an intervention tool. The 30 main factors affecting preventable deaths in the field of tactical medicine. Turnstiles, one of these materials, are increasingly being used in civilian settings. 2 regulations regarding the use among first responders, such as emergency ambulances It is becoming widespread, and useful scientific publications are being produced in this field. Tourniquets are used to stop serious bleeding, especially in extremities such as arms and legs. They are mechanical pressure devices developed to control [pressure]. Their use is 5. It is quite practical and can be implemented in a short time by a trained person. TCCC In the protocol, "if the location of the bleeding cannot be seen and the bleeding is severe, directly "Applying a turnstile" is the basic approach. Commonly used turnstiles on the market (e.g., CAT, SAM XT, SOF-T) 10 It usually has a rod locking mechanism (windlass system). In this system, the pressure needed to stop the bleeding, a rod (cavalry arm) This is achieved by rotating it. However, these systems have various technical and practical aspects. It has disadvantages: 1. Multi-Stage and Complex Fixation Process After the windlass handle is turned, the user places this handle into a hook (C-hook). must pass. Then, the arm should be wrapped with a Velcro safety band. This procedure is especially suitable when it is stressful, dimly lit, or requires one-handed intervention. It is challenging in certain situations. 2. Risk of Fabric Folding and Texture Damage Because the belt is tightened at a certain point by turning the winch handle, usually Fabric folding or uneven print distribution at the bottom of the arm It emerges. 30 3 This can cause both tissue damage and effective pressure. This may lead to it being impossible to implement. 3. Part Compatibility Issues and Time Loss The hook or socket to which the windlass arm is to be attached is not always aligned; the user You may waste time installing this part. If the arm is not positioned correctly, the tourniquet may loosen or become ineffective. It may decrease. 10 4. A system prone to user errors. The user makes mistakes in the steps, especially when interfering with the situation using only one hand. or the inability to do it sequentially reduces the system's effectiveness. 15 In the Sahara region, environmental factors such as rain, mud, and blood act as fixatives. This can make using its parts even more difficult. The current European patent, numbered EP4456803B1, concerns the “styptic harness 20 The topic is a tourniquet system, defined as a "tourniquet," used to stop bleeding. It is acquired. In the invention in question, the stabilizer located on the turnstile body The aim is to quickly control bleeding with these structures. The structure; a belt-like strap, a pressure-applying element, and a securing lock It consists of mechanisms. 25 However, this technical solution has the following disadvantages: - The structure where pressure is applied is single-layered, and the strap applies pressure to the extremity. Pressure can be unevenly distributed. 30 4 - The locking mechanism requires the user to perform multiple actions. because of this, it can be applied quickly and with one hand, especially in stressful environments. It makes things more difficult. - A pressure-boosting mechanism similar to a winch handle is not integrated, which is 5 This makes it difficult to achieve effective pressure. In these respects, the structure offered by the invention is advantageous in terms of both implementation time and user experience. It does not provide sufficient technical efficiency in terms of ease of use. International patent application number WO2024076335A1 provides users with emergency The invention offers a turnstile system that can be used during interventions. within this scope, a rotating mechanism including a belt and a fastening structure. The system is described. It has a structure similar to a winch handle, and the system is manual. The process involves tightening and then locking. 15 However, the current application has some technical shortcomings: - The winch arm must be manually seated in a socket before being fixed in place. This is necessary. This process causes a loss of time during implementation. 20 It is possible. - There is a risk of the fabric folding in the turning area of ​​the belt, which can cause problems for both It increases tissue damage and also leads to pressure imbalance. - The locking mechanism is defined as an independent structure, and the system It does not offer an integrated solution. In these respects, the multi-step fastening structure, which is not user-friendly, is especially problematic for single-step applications. This creates a significant weakness in tactical situations requiring manual application. 30 South Korean patent number KR102203129B1 describes a "dial type tourniquet". a system called turnstile pressure is controlled by a dial mechanism It offers a solution that can be adjusted via a fixed strap and this structure. It includes a rotating wheel that tensions the belt. The user rotates the wheel to adjust the tension. You can tighten the tourniquet and thus control the bleeding. 5 However, there are some technical disadvantages: - Although the gear system provides precise control, it is mechanically more complex and It carries a risk of malfunction during use. 10 - In situations requiring quick and forceful intervention, the tourniquet can be operated with one hand. Not suitable for application. - After the wheel spinning process is complete, there is also a locking mechanism or a 15 A fastening process may be required, which places an additional burden on the user. This structure is more suitable for use in controlled environments, but also for tactical applications. It does not provide the necessary speed and simplicity in medical applications. The Ukrainian utility model certificate numbered UA151561U, as described above, It belongs to the same family as the European patent EP4456803B1 and has similar technical elements. This document also includes the turnstile system's belt, fastening structure, and pressure. A system has been defined in which the components used to create the system are the implementing parts. Disadvantages: - The turnstile is based on classic fastening methods and has an integrated arm. It does not offer a structure. 6 - Pressure application is limited and double pressure will ensure homogeneous distribution to the tissue. There is no belt-driven structure. - Manual intervention from the user is expected during the fastening phase, this This also negatively affects the speed of implementation. 5 This document outlines innovations that will meet today's advanced technical needs. It is not offered as a solution; it is considered a variation of the existing system. The US application (US20090062842A1) and the 10 applications based on it are included in the current technique. The registered version is US7892253B2, with a rod-shaped core (winch arm). It includes turnstile systems with a mechanism. In this system, an outer casing (outer sleeve), an inner strap that slides inside this sleeve, and this inner strap It features a windlass mechanism used for tensioning. In tourniquet application, the outer sheath is wrapped around the extremity, and the inner strap is attached to the winch handle 15 It is connected and the belt is tensioned by rotating the lever. Then the lever is positioned within the system. The area is secured with a holder or "hooked catch" to maintain pressure. Additionally... The strap is fastened using buckles with a toothed structure that supports the fastening process. It is prevented from coming loose. However, this technical solution has some disadvantages: - The turnstile's fixing mechanism is multi-stage and requires step-by-step instruction from the user. Intervention is required. The winch handle must be turned and placed in the holder, and locking, especially stressful, requiring one-handed intervention 25 In these situations, it creates a waste of time and a risk of error for the practitioner. - The pressure can turn into localized pressure because the inner belt is pressed at a specific point. They can gather and create high pressure in confined spaces. This situation affects the tissue. It can increase the risk of destruction. 30 7 - Components—outer sheath, inner strap, capstan handle, holding mechanisms— They are relatively independent of each other. This does not reduce the number of parts. It does not reduce potential losses and mechanical difficulties. - Also, one-handed application performance may be limited with this configuration; emergency 5 in these situations speed, safety and ease of implementation are fully required. It may not be possible. In these respects, although the structure in the US application describes a basic winch system, In terms of ease of application, tissue preservation and pressure uniformity, the current technique is 10. It is unable to fully meet the needs. The aim of our invention is to eliminate the disadvantages mentioned above. facilitating application, offering a more homogeneous pressure distribution, and conforming to the tissue. an advanced fastening mechanism that minimizes the damage done and these 15 The goal is to provide a winch arm structure that works integrated with the mechanism; furthermore, the winch arm What distinguishes our mechanism from other inventions is that the force applied by the user It is less. The invention, a hemostatic tourniquet, consists of a 20-inch torso strap integrated into the body. It contains a stabilizing mechanism, and through this stabilizing mechanism Thanks to the double belt system, the pressure application process is more controlled and It is performed in a balanced manner. The upper part of the fixing mechanism positioned centered on the surface and secured from the right and left corners. The windlass arm is integrated into the mechanism via connecting devices mounted on it. 25 It has been done. As the windlass handle is turned, the double belt passing through the securing mechanism simultaneously This tension is applied by attaching a belt along the entire length of the torso strap. The double strap ensures even pressure across the entire width of the turnstile. 30 Thus, the problem of the fabric folding under the winch arm, seen in classical systems, is eliminated. 8 This eliminates the pressure, thereby reducing tissue damage. It spreads evenly over a wide area, not just to a specific point. The tension created by turning the windlass handle is inside the fastening mechanism. The pressure is transmitted to the pressure-sensitive locking system designed in its structure, and here 5 The resulting pressure force causes the system to lock automatically. This structure Thanks to this, no separate locking or securing step is required when installing the turnstile. Without delay, rapid and safe hemostasis is achieved. Brief description of the invention 10 Commonly used hemostatic tourniquets in current technology are torso straps. After being wrapped around it, the strap is tightened by turning the winch handle. It withstands. During operation, after the user turns the winch handle, this handle... It must also be secured by placing it in an additional hook or slot attached to the body. This multi-stage process is particularly stressful, requires one-handed intervention, or is difficult to navigate in dimly lit environments. In brightly lit environments, this can lead to wasted time and user error. Furthermore, Because the winch arm applies direct pressure to the body strap, the fabric... This involves folding and the concentration of pressure at a single point, which It leads to both tissue damage and uneven distribution of pressure. It prevents. 20 In the hemostatic tourniquet that is the subject of this invention, these disadvantages have been eliminated. Body The strap has an integrated fastening mechanism, The double belt system, which passes through the mechanism, runs the entire length of the body belt. It is attached. At the top of the stabilizing mechanism, 25 is positioned to center the structure. The windlass arm is mounted on its right and left edges by means of connecting devices. It is found. As the user turns the windlass handle, the pair passes through the locking mechanism. The belt is simultaneously tensioned, and this tension is applied across the entire width of the body belt, 30 The pressure is distributed homogeneously. Thus, the pressure does not concentrate at a specific point. 9 Instead, it spreads evenly over a wide area; fabric folding is prevented and Tissue damage is minimized. The tension created when the windlass is turned is located in the internal structure of the locking mechanism. The pressure is transferred to the pressure-sensitive locking system located in this position, and the system uses this pressure 5 It locks automatically with force. Thanks to this structure, the current technology... Quick and safe operation without the need for the winch arm to be additionally inserted into a socket. A fixation is provided. Application Scenario and Working Principle 10 The invention, a hemostatic tourniquet, allows the user to make their own tourniquet in case of emergency bleeding. can be applied quickly and effectively by oneself or another person It is designed in this way. The practitioner tightens the body strap of the tourniquet where the bleeding occurs. By wrapping it around the affected extremity (e.g., arm or leg), pre-tightening 15 It performs its operation. During this process, the body strap, which is integrated onto it, It also positions the fixing mechanism in the relevant position. The fixing mechanism The double belt system, which passes through it, is connected to the body belt from this point onwards. It is vertically integrated along its length. The user can position the upper part of the stabilizing mechanism. located in that section and connected to the right and left edges of the structure with connecting apparatuses 20 He starts turning the windlass handle, which is mounted in a centered position. As the windlass arm is turned, the pair inside the stabilizing mechanism... The belt system is tensioned simultaneously. This tension force is mechanically transmitted to the body. It is distributed evenly across the entire width of the belt. Thus, 25 to the extremity The applied pressure is distributed homogeneously over a wide area instead of being concentrated at a local point. It spreads in this way. This pressure distribution principle minimizes pressure on tissues. By doing so, it both reduces tissue damage and increases hemostatic efficacy. Similarly In the techniques available at the time, the fabric was folded under the winch's arm. Problems such as jamming are eliminated. 30 The tensile stress created by rotating the windlass arm is transmitted through the internal stabilizing mechanism. directly to the pressure-sensitive locking system located in its structure is transmitted. A voltage force above a certain threshold triggers this system. It provides automatic locking. Thus, unlike existing turnstiles, the winch handle does not lock automatically. Additionally, it provides quick and secure fastening without the need to be placed in a socket. 5 This is achieved. The user can both tighten and lock with just a rotating motion. It saves time by completing the process in a single step and prevents application errors. It minimizes the risk. In conclusion, the subject of this invention is a hemostatic tourniquet: • Faster and easier to implement, 10 • Suitable for one-handed use,  Requires less force, • Provides homogeneous pressure distribution without damaging the tissue, • An integrated fastening solution that requires no additional parts. It offers. 15 Detailed description of the invention The turnstile system implemented to achieve the objectives of this invention is attached.
