Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an integrated device for intelligent hemostasis and pressure fixation of emergency traumatic bleeding. Background Technology

[0002] In emergency trauma care, especially in pre-hospital emergency settings, controlling external bleeding is a crucial step in saving lives. Within the golden treatment time after trauma, the ability to quickly and effectively stop bleeding directly impacts the patient's safety. Traditional hemostasis methods mainly include direct compression, tourniquets, tamponade, and pressure bandages. While these methods are effective to some extent, they generally suffer from high operational dependence, low standardization, and difficulty in dynamic adjustment. For example, some ordinary tourniquets, if insufficiently pressurized, cannot effectively block blood flow, while excessive pressure or prolonged use can easily lead to limb ischemia, nerve damage, or even necrosis. Pressure bandages, on the other hand, are limited by the rescuer's experience, making it difficult to control the pressure and lacking guarantees of fixation stability.

[0003] Furthermore, in cases of bleeding from multiple traumas or complex anatomical sites (such as the shoulder, groin, and pelvis), existing devices may struggle to conform to the wound surface and maintain continuous, effective pressure, easily leading to hemostasis failure due to limb movement or loosening of the bandage. Simultaneously, traditional methods typically treat hemostasis and immobilization as two separate steps, requiring the use of different instruments, which not only prolongs treatment time but also increases operational complexity. Moreover, most existing hemostatic devices lack adjustable functions, failing to adjust pressure according to the actual situation at the wound site, potentially making them unsuitable for the needs of traumatic bleeding of varying severity. Additionally, the complexity of some devices in operation may delay treatment in emergency situations due to their cumbersome operation, hindering rapid intervention by non-professionals within the golden window of opportunity.

[0004] Therefore, this invention proposes an integrated intelligent hemostasis and pressure fixation device for emergency trauma bleeding. The device collects the pressure data of the wound site through a feedback mechanism, which can capture pressure changes. The adjustment mechanism adjusts the fixation force of the bladder according to the signal from the feedback mechanism, so that the hemostasis pressure can be maintained within a safe and effective range, thereby improving the convenience and efficiency of emergency treatment. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an integrated intelligent hemostasis and pressure fixation device for emergency trauma bleeding. This device collects pressure data at the wound site via a feedback mechanism, capturing pressure changes. An adjustment mechanism then adjusts the fixation force of the bladder based on the feedback signal, ensuring that the hemostasis pressure remains within a safe and effective range, thereby improving the convenience and efficiency of emergency treatment.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: an integrated device for intelligent hemostasis and pressure fixation of emergency trauma bleeding, comprising a main bladder for conforming to the wound site, a plurality of connecting bladders being fixedly connected to the main bladder circumferentially, a fixing strap being fixedly connected to the side of each connecting bladder away from the main bladder, and an adjustment mechanism for adjusting the fixing force of the device being provided inside each connecting bladder.

[0007] It also includes a feedback mechanism, which is used to obtain the contact pressure of the main capsule and connecting capsule on the wound site, and control the operation of the adjustment mechanism based on the contact pressure to change the fixation force of the main capsule and connecting capsule on the wound site.

[0008] The technical principles of the above solution are as follows:

[0009] Through the synergistic action of the main capsule and connecting capsules, intelligent compression hemostasis and stable fixation of the wound site are achieved. The main capsule covers the bleeding area, providing basic hemostatic pressure; the circumferentially distributed connecting capsules encircle the limb or torso with fixation straps, forming an overall restraint structure. The adjustment mechanism can adjust the tension of each connecting capsule according to actual needs, thereby changing the overall pressure on the wound area. The feedback mechanism collects pressure data of the main capsule and connecting capsules in contact with the skin in real time, converts the pressure data into control information and transmits it to the adjustment mechanism, driving the adjustment mechanism to contract or relax, achieving precise pressure control. This ensures sufficient pressure to achieve hemostasis and fixation while avoiding excessive pressure that could cause secondary injury, making the device adaptable to different trauma situations in emergency trauma scenarios.

[0010] The above approach has the following beneficial effects:

[0011] 1. This solution establishes a pressure regulation mechanism through the synergistic action of the main capsule and connecting capsules. A feedback mechanism collects pressure data at the wound site, capturing pressure changes. The adjustment mechanism adjusts the capsule fixation force based on the feedback signal, ensuring effective pressure for hemostasis while avoiding secondary damage such as tissue ischemia and necrosis caused by excessive pressure in traditional hemostatic devices. This coordinated control mode maintains hemostatic pressure within a safe and effective range, making it suitable for complex trauma scenarios. It provides a safer and more reliable hemostasis solution for emergency treatment, reducing the risk of complications caused by improper hemostasis procedures.

[0012] 2. The main capsule of this design can conform to the bleeding area of ​​the wound, providing targeted hemostatic pressure; the circumferentially distributed connecting capsules can flexibly wrap around different parts such as the limbs or torso through fixing straps, forming an overall restraint structure. The adjustment mechanism can independently adjust the tension of each connecting capsule, and can change the overall pressure on the wound area according to the shape of the wound site, the severity of the injury, and individual differences of the patient, improving the convenience and efficiency of emergency treatment.

[0013] 3. After initial fixation with the fixation strap, the feedback and adjustment mechanisms of the device can be activated. This reduces manual operation steps. The feedback mechanism collects pressure data in real time and transmits it to the adjustment mechanism to complete pressure regulation. This reduces the operational difficulty and workload for medical staff, enabling hemostasis and fixation to be completed in a short time, buying valuable treatment time for trauma patients, and improving the overall quality and safety of emergency care.

[0014] Furthermore, the adjustment mechanism includes several first and second links located inside the connecting bladder. The two ends of adjacent first and second links are hinged to each other, and the middle parts of the first and second links are hinged to each other. A connecting seat is fixedly connected to the connection between the connecting bladder and the main bladder. The end of the first link away from the fixing band is hinged to the connecting seat, and the end of the second link away from the fixing band is slidably engaged with the connecting seat. The end of the first link near the fixing band is slidably engaged with the inner wall of the connecting bladder, and the end of the second link near the fixing band is hinged to the inner wall of the connecting bladder.

[0015] Beneficial effects: Through multi-point hinges and sliding connections between the first and second links, a variable-form linkage structure is formed, enabling adjustment of the length and tension of the connecting sac. When the link assembly expands or contracts, it can simultaneously change the restraint force and the pressure of the sac against the wound site, resulting in rapid response and stable movement.

[0016] Furthermore, each connecting seat is equipped with a retraction assembly for driving the first and second connecting rods to move closer together; the retraction assembly includes a controller and several lead screws rotatably fitted on the connecting seat, each lead screw having a nut seat threaded onto its outer wall, and the end of the second connecting rod away from the fixing belt is hinged to the outer wall of the nut seat; each connecting seat has a driving component fixedly connected to its top, and the driving component is electrically connected to the controller; the output shaft of the driving component is fixedly connected coaxially to the lead screw.

[0017] Beneficial effects: By driving the lead screw to rotate through the controller, the nut seat moves linearly, thereby adjusting the position of the second link, so that the first link and the second link can retract or expand in coordination, thereby adjusting the fixing force, ensuring that the compression force is within a safe and effective range, and improving the intelligence level and clinical applicability of the device.

[0018] Furthermore, the connecting bladder is equipped with a delivery assembly for supplying gas to the main bladder. The delivery assembly includes several flow guide valves, all of which are electrically connected to the controller. Each connecting bladder is equipped with a buffer bladder, which is connected to the main bladder through a flow guide valve. The first connecting rod and the second connecting rod are both located above the buffer bladder.

[0019] Beneficial effects: By connecting the buffer bladder and the main bladder through a flow-directing valve, gas can flow between the two as needed, providing hemostatic pressure support to the main bladder. The buffer bladder not only serves as a gas source reserve, but the first and second connecting rods located above it generate a driving force during adjustment, causing the buffer bladder to deform and thus transferring gas to the main bladder. This combination of mechanical adjustment and gas pressure control enhances the device's adaptability to different trauma scenarios and improves hemostatic reliability.

[0020] Furthermore, the feedback mechanism includes several pressure sensors, all of which are fixedly connected to the bottom of the main bladder and the connecting bladder; the controller is used to acquire the pressure signals emitted by the pressure sensors and control the operation of the drive components and the flow guide valve based on the pressure signals.

[0021] Beneficial effects: Pressure sensors located at the bottom of the main capsule and connecting capsule acquire the pressure distribution in the wound area and transmit the data to the controller. The controller then adjusts the coordinated action of the drive mechanism and the flow-guiding valve to balance hemostatic pressure and fixation tension, ensuring that the compression force is within a safe range that effectively stops bleeding without damaging tissue.

[0022] Furthermore, each connecting seat is fixedly connected to a guide rod, and each nut seat is slidably fitted onto the guide rod.

[0023] Beneficial effects: The guide rod provides a stable linear motion trajectory for the nut seat, limiting the radial offset or wobbling generated during the rotation of the lead screw, and ensuring smooth and precise operation of the linkage mechanism.

[0024] Furthermore, a humidity sensor is fixedly connected to the bottom of the main body. The controller is used to receive humidity information emitted by the humidity sensor and control the operation of the drive components and flow guide valve based on the humidity information.

[0025] Beneficial effects: The humidity sensor can monitor humidity changes caused by wound exudate or blood, providing auxiliary information for assessing bleeding status. The controller combines humidity information with pressure signals to adjust the operating status of the drive components and flow control valve, improving the device's ability and accuracy in detecting bleeding responses and enhancing the safety and effectiveness of emergency procedures.

[0026] Furthermore, a hemostatic layer is fixedly connected to the bottom of the main capsule and the connecting capsule.

[0027] Beneficial effects: The hemostatic layer can directly contact the wound surface, which not only improves the efficiency of initial hemostasis but also reduces reliance on high pressure and lowers the risk of tissue damage caused by prolonged pressure. Simultaneously, its flexible structure conforms well to the capsule, enhancing the device's comprehensive treatment capabilities in complex trauma scenarios.

[0028] Furthermore, a buzzer is fixedly connected to the outer wall of the main capsule, and the controller is used to operate the buzzer based on pressure signals and humidity information.

[0029] Beneficial effects: The buzzer can issue audible and visual alerts based on pressure signals and humidity information, enabling proactive warnings of abnormal conditions. When the pressure is too low to effectively stop bleeding, or when the humidity is too high to indicate continuous bleeding, the buzzer will sound to remind rescuers or the injured person to intervene in time. If the pressure is too high and there is a risk of tissue damage, it can also issue a warning, improving the interactivity and safety of the device.

[0030] Furthermore, the end of the fixing strap away from the connecting bag is fixedly connected with Velcro.

[0031] Beneficial effects: Velcro allows for quick and easy wrapping, adjustment, and fixation, adapting to different limb circumferences and body shapes. It maintains a snug fit during handling or minor limb movements, preventing loosening and enhancing the device's practicality and versatility. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The following detailed description illustrates the specific implementation method:

[0040] Example 1:

[0041] As attached Figures 1-3 As shown: An integrated intelligent hemostasis and pressure fixation device for emergency trauma bleeding includes a main capsule 1 for fitting the wound site. Several connecting capsules 2 are circumferentially fixed to the main capsule 1. In this embodiment, both the main capsule 1 and the connecting capsules 2 are made of flexible material. A fixing strap 3 is fixedly bonded to the side of the connecting capsules 2 away from the main capsule 1. Each connecting capsule 2 is provided with an adjustment mechanism for adjusting the fixing force of the device.

[0042] This embodiment also includes a feedback mechanism, which is used to obtain the contact pressure of the main capsule 1 and the connecting capsule 2 on the wound site, and control the operation of the adjustment mechanism based on the contact pressure to change the fixation force of the main capsule 1 and the connecting capsule 2 on the wound site.

[0043] The adjustment mechanism includes several first connecting rods 4 and second connecting rods 5 located inside the connecting bladder 2 (such as...). Figure 3 As shown), the two ends of the adjacent first link 4 and second link 5 are hinged to each other, and the middle parts of the first link 4 and the second link 5 are hinged to each other; a connecting seat 6 is fixedly bonded to the connection between the connecting bladder 2 and the main bladder 1; the end of the first link 4 away from the fixing band 3 is hinged to the connecting seat 6, and the end of the second link 5 away from the fixing band 3 is slidably engaged with the connecting seat 6; the end of the first link 4 near the fixing band 3 is slidably engaged with the inner wall of the connecting bladder 2, and the end of the second link 5 near the fixing band 3 is hinged to the inner wall of the connecting bladder 2.

[0044] Each connecting seat 6 is equipped with a retraction assembly for driving the first connecting rod 4 and the second connecting rod 5 to move closer together; the retraction assembly includes a controller and several lead screws 7 rotatably fitted on the connecting seat 6, each lead screw 7 having a nut seat 8 threadedly fitted on its outer wall, and the end of the second connecting rod 5 away from the fixing belt 3 is hinged to the outer wall of the nut seat 8; each connecting seat 6 has a drive component 9 screwed to its top, which in this embodiment is a motor, and each drive component 9 is electrically connected to the controller; the output shaft of each drive component 9 is coaxially fixedly connected to the lead screw 7 through a coupling.

[0045] The connecting bladder 2 is also equipped with a gas delivery assembly for supplying gas to the main bladder 1. The delivery assembly includes several flow guide valves, all of which are electrically connected to the controller. Each connecting bladder 2 is equipped with a buffer bladder 10, which is connected to the main bladder 1 via flow guide valves. The first connecting rod 4 and the second connecting rod 5 are both located above the buffer bladder 10. In this embodiment, a pad is provided on the buffer bladder 10. The first connecting rod 4 and the second connecting rod 5 are both connected to the buffer bladder 10 via the pad, so that when the scissor structure moves, the pad provides a cushioning effect, which can cause the buffer bladder 10 to deform.

[0046] The feedback mechanism includes several pressure sensors, all of which are fixedly attached to the bottom of the main body 1 and the connecting body 2; the controller is used to acquire the pressure signals emitted by the pressure sensors and control the operation of the drive unit 9 and the flow guide valve based on the pressure signals.

[0047] The specific implementation process is as follows: After the device is deployed at the wound site, the pressure sensors distributed at the bottom of the main capsule 1 and the connecting capsule 2 monitor the real-time pressure during the application and transmit the real-time pressure to the controller; the controller compares the real-time pressure with the preset safe hemostatic pressure threshold; if insufficient pressure or excessive pressure is detected, the controller issues an adjustment command.

[0048] The controller drives the motor to start based on adjustment commands. The motor output shaft drives the lead screw 7 to rotate, and the nut seat 8, which is threaded with the lead screw 7, subsequently undergoes linear displacement along the axis of the lead screw 7. This displacement causes one end of the second connecting rod 5, which is hinged to it, to move. Since the second connecting rod 5 and the first connecting rod 4 are cross-hinged in the middle, and their ends respectively form sliding or hinged constraints with the connecting seat 6 and the inner wall of the connecting capsule 2, the movement of the nut seat 8 causes a continuous change in the shape of the entire scissor linkage assembly. Figure 2 and Figure 3 For example, if it is necessary to increase the contact pressure, the screw 7 drives the nut seat 8 to move downward. This action pushes the second link 5, increasing the cross angle between the first link 4 and the second link 5.

[0049] This angular change generates a coordinated action. Axially (in the direction surrounding the limb), it causes the hinge points at both ends of the first link 4 and the second link 5 to move closer together, shortening the entire link assembly and the connecting bladder 2 that encloses it, thereby tightening the fixing strap 3 and enhancing the circumferential fixing force. Radially (perpendicular to the limb), the intersection points of the links move downward, increasing the support thickness (support height direction) of the connecting bladder 2, thus supporting the connecting bladder 2 to conform to the limb surface. The combined effect of axial tightening and radial lifting creates a continuously strengthening wrapping and squeezing effect from the outside in on the central main bladder 1, thereby increasing the fitting pressure of the device.

[0050] Simultaneously, the controller opens the flow valve inside the connecting capsule 2. As the adjusting mechanism operates, the scissor linkage compresses the buffer capsule 10 below it. Under pressure, the gas inside the buffer capsule 10 is injected into the main capsule 1 through the opened flow valve. The main capsule 1 thus becomes moderately inflated, better conforming to the wound and achieving pressure application.

[0051] The mechanical tightening of the regulating mechanism and the inflation of the delivery component work in tandem to rapidly and steadily increase the pressure of the main capsule 1 on the wound site to the preset target value. When the pressure signal from the pressure sensor reaches the target value, the controller commands the motor to stop, the flow control valve to close, and the device to enter a pressure holding state. Due to the self-locking characteristic of the lead screw 7 and the nut seat 8, the scissor linkage mechanism can maintain the contracted state, ensuring that the contact pressure remains stable.

[0052] Conversely, when the feedback mechanism detects excessive pressure (such as due to limb swelling) or the need for release, the controller will command the motor to reverse, driving the nut seat 8 to move in the opposite direction and pushing the scissor linkage to extend. This will cause the connecting sac 2 to elongate axially and thin radially, simultaneously weakening the circumferential force and internal support force, thereby safely and controllably reducing the hemostatic pressure.

[0053] The entire motion process in this embodiment demonstrates the intelligence and reliability of the device. It uses pressure feedback as the basis for judgment, utilizes a single motor drive as the power source, and converts linear motion into the linkage output of the fitting components through a scissor linkage. In conjunction with air circuit compensation, it achieves adaptive adjustment of the pressure-relieving force.

[0054] Example 2:

[0055] As attached Figure 3 As shown, the difference from Embodiment 1 is that the connecting seat 6 is fixedly connected to the guide rod 11 with screws, and the nut seat 8 is slidably fitted on the guide rod 11.

[0056] The specific implementation process is as follows: The connecting seat 6 is fixedly installed on the frame or base with screws to ensure its stable position and immovability. In this embodiment, each connecting seat 6 is provided with a through hole for installing the guide rod 11. One end of the guide rod 11 is fastened to the connecting seat 6 with a screw, so that its axis is parallel to the movement direction of the equipment, thereby providing a guiding reference for subsequent moving parts.

[0057] As part of the transmission assembly, the nut seat 8 has a threaded hole that mates with the lead screw and a sliding hole that matches the guide rod 11. The nut seat 8 is fitted onto the guide rod 11 through this sliding hole, allowing it to slide freely along the axial direction of the guide rod 11, preventing rotation or displacement. This structure effectively restricts the degrees of freedom of the nut seat 8 during movement, allowing it to only perform linear reciprocating motion in a predetermined direction, thus ensuring transmission accuracy and operational stability.

[0058] When the drive motor rotates the lead screw, the nut seat 8 moves axially under the drive of the lead screw, while simultaneously achieving smooth, yaw-free linear motion under the constraint of the guide rod 11. Throughout the process, the guide rod 11 bears the lateral force and vibration load, preventing the lead screw from bearing bending moment and extending the service life of the transmission components.

[0059] Example 3:

[0060] The difference from Embodiment 2 is that a humidity sensor is also fixedly attached to the bottom of the main body 1. The controller is used to receive the humidity information emitted by the humidity sensor and control the operation of the drive component 9 and the flow guide valve based on the humidity information.

[0061] The specific implementation process is as follows: After the device is deployed at the wound site, pressure sensors located at the bottom of the main capsule 1 and connecting capsule 2 continuously monitor the contact pressure with the body surface, while a humidity sensor newly added to the bottom of the main capsule 1 simultaneously detects the status of wound exudate (such as blood) in real time. When the humidity sensor detects a significant fluid signal, combined with the initial pressure feedback from the pressure sensor indicating insufficient pressure, the controller determines that there is active bleeding and immediately triggers the coordinated pressurization mode. The controller simultaneously sends commands to the adjustment mechanism and delivery components.

[0062] Throughout the pressurization and holding period, the humidity sensor continuously monitors the humidity. If the humidity value remains high or rises again, the controller can determine that hemostasis is incomplete. Even if the pressure has reached the normal target, it can instruct a slight increase in pressure or maintain the current pressure for a longer period. Conversely, if the pressure is stable and the humidity drops significantly and remains at a low level, the controller can determine that the bleeding has been effectively controlled. To prevent excessive pressure on the limb, it can instruct the motor to slightly reverse, driving the scissor linkage to move in the opposite direction, causing the connecting bladder 2 to slightly extend axially and thin radially, thereby intelligently adjusting the pressure to a lower safe maintenance value and achieving dynamic optimization.

[0063] Example 4:

[0064] The difference from Example 3 is that a hemostatic layer is also fixedly bonded to the bottom of the main capsule 1 and the connecting capsule 2. In this example, the hemostatic layer is fixedly bonded to the bottom outer surfaces of the main capsule 1 and the connecting capsule 2 using a biocompatible adhesive (such as medical silicone adhesive or cyanoacrylate quick-drying adhesive). This hemostatic layer is made of a material with rapid water absorption, coagulation promotion, or physical pressure hemostasis functions, such as chitosan fiber nonwoven fabric, gelatin sponge, oxidized regenerated cellulose (ORC), zeolite particle composite dressing, or a combination thereof.

[0065] The specific implementation process is as follows: The shape of the hemostatic layer matches the bottom contour of the main capsule 1 and the connecting capsule 2 to ensure close contact with the wound surface during use. When the device is applied to the bleeding site, the main capsule 1 and the connecting capsule 2, under the action of air pressure and pressing, allow the hemostatic layer to fully contact the wound surface. On the one hand, this reduces blood flow through physical compression, and on the other hand, it accelerates the blood coagulation process by utilizing the chemical or biological activity of the hemostatic material.

[0066] In some preferred embodiments, the hemostatic layer may also be loaded with hemostatic drugs (such as thrombin or adrenaline), which release the active ingredients slowly upon contact with blood, further improving hemostatic efficiency. Simultaneously, the outer side of the hemostatic layer may be provided with a breathable but impermeable protective membrane to prevent contamination during transportation or storage, and this membrane is removed before use.

[0067] Since the hemostatic layer is directly bonded to the bottom of the capsule, no additional fixing structure is required, simplifying the overall design and improving ease of use and reliability. It is suitable for battlefield first aid, surgical assistance, or pre-hospital trauma treatment, and can achieve effective hemostasis in a short time, reducing the risk of blood loss.

[0068] Example 5:

[0069] As attached Figure 1 As shown, the difference from Embodiment 4 is that a buzzer 12 is also fixedly bonded to the outer wall of the main capsule 1. The controller is used to operate the buzzer 12 based on pressure signals and humidity information. In this embodiment, the buzzer 12 is electrically connected to the controller and is used to emit audible and visual warnings (integrated LED) or audio alarm signals to remind the user to intervene in a timely manner. Furthermore, the buzzer 12 is preferably a low-power, high-loudness piezoelectric or electromagnetic miniature buzzer 12, whose operating voltage is matched with the controller power supply, and has an IP65 or higher protection rating to adapt to humid or outdoor environments.

[0070] The specific implementation process is as follows: The controller is connected to both a pressure sensor and a humidity sensor, receiving pressure signals from the pressure sensor and humidity information collected by the humidity sensor in real time. The controller has preset pressure safety threshold ranges and normal humidity ranges. During device operation, the controller continuously monitors and judges these two types of parameters.

[0071] When an abnormal pressure is detected (e.g., excessive pressure may cause tissue compression necrosis, or insufficient pressure may prevent effective hemostasis / fixation), the controller will activate buzzer 12 to emit intermittent or continuous alarm sounds; when excessive humidity is detected (which may indicate excessive wound exudation or bleeding), the controller will also trigger buzzer 12 to alarm, prompting the user to check the wound condition.

[0072] In the event of a combined abnormal situation where both pressure and humidity exceed the normal range, the controller can control the buzzer 12 to issue multi-level alarms at a specific frequency or coded tone (such as a fast flashing short beep) to distinguish the type of fault.

[0073] In addition, in some preferred embodiments, the controller can also simultaneously send alarm information to a mobile terminal or monitoring platform via a wireless module (such as Bluetooth or LoRa) to achieve remote early warning.

[0074] Example 6:

[0075] As attached Figure 1 As shown, the difference from Embodiment 5 is that the ends of the fixing straps 3 away from the connecting pouch 2 are all fixedly glued with Velcro 13. Specifically, one side (e.g., the hook side) of the Velcro 13 is glued to the outer surface of the free end of each fixing strap 3 by medical-grade pressure-sensitive adhesive or hot melt adhesive, while the corresponding position of the opposite fixing strap 3 is glued with the matching other side (e.g., the napped side), thereby forming a quick-release fixing structure that can be repeatedly opened and closed.

[0076] The specific implementation process is as follows: During use, the user applies the main capsule 1 and connecting capsule 2 to the target area (such as a limb wound), stretches the fixing strap 3 around the limb, and attaches the free end of the Velcro 13 to the preset mating area. By adjusting the adhesive position, it can flexibly adapt to limbs of different circumferences, achieving tightness adjustment and ensuring that the main capsule 1 is stably fitted without slippage. At the same time, the flexible connection characteristics of the Velcro 13 can reduce the local pressure discomfort that may be caused by traditional buckles.

[0077] This design simplifies donning and disassembly, making it easy to do with one hand and improving the reusability and ease of cleaning of the device. When it is necessary to change the hemostatic layer, check the wound, or adjust the pressure, simply tear off the Velcro 13 to quickly release the fixation without completely removing the entire device.

[0078] Furthermore, the material of the Velcro 13 is preferably an antibacterial and sweat-resistant nylon-based composite fabric to ensure long-term reliability. In some preferred embodiments, the Velcro 13 area may also integrate scale markings to help users achieve symmetrical or consistent pressure binding effects.

[0079] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
