Abstract
Description
Technical Field
[0001] The present application relates to the field of medical equipment, and in particular to a rapid hemostasis structure based on multiple adaptations and an application method. Background Art
[0002] In medical emergency and surgery, rapid and effective hemostasis is crucial. Whether on the battlefield or in the operating room of a hospital, the speed and effect of hemostasis directly affect the patient's life safety and postoperative recovery. However, traditional hemostasis devices often face problems such as poor adaptability, low hemostasis efficiency, and difficult operation when dealing with complex wounds. These problems may lead to delayed hemostasis, increased risk of infection, and even life-threatening.
[0003] Traditional hemostasis methods mainly rely on materials such as gauze, hemostatic powder and tourniquet. These materials can usually play a good hemostatic effect when dealing with simple superficial wounds. However, when faced with irregular or deep wounds, the limitations of these materials become apparent. Among them, gauze and hemostatic powder are difficult to completely cover the wound surface in complex wounds, resulting in incomplete hemostasis. In addition, these materials may move or fall off in the wound, resulting in unstable hemostasis and increasing the risk of re-bleeding.
[0004] In response to the many shortcomings of traditional hemostasis methods, related research has gradually led to the emergence of hemostasis devices that can rely on automatic deployment structures to adapt to superficial wounds or deep wounds. However, in emergency environments, time is of the essence. The deployment of such hemostasis devices takes a long time and they only adapt to a single type of wound, making it difficult to meet the hemostasis needs of multiple types of wounds in complex environments. Summary of the invention
[0005] In view of the above problems, the present invention provides a rapid hemostasis structure based on multiple adaptations and an application method to solve the problems of long hemostasis time and narrow wound adaptability of existing hemostasis devices.
[0006] In the first aspect, the present invention provides a rapid hemostasis structure based on multiple adaptations, and the technical solution is: A rapid hemostasis structure based on multiple adaptations, including: The booster mechanism has a limited space inside; A multiple adaptation mechanism is built into the confined space and is in a folded state in the confined space; wherein the multiple adaptation mechanism includes: The surface support part has at least two peripheral rods, and a plurality of the peripheral rods enclose a surface area, and a hemostatic fiber membrane is arranged on the surface area; A three-dimensional support portion, comprising a central rod and a connecting rod mechanism, wherein the connecting rod mechanism is respectively hinged to the central rod and the peripheral rods to form a three-dimensional area; an elastic member connected to the connecting rod mechanism, and in the folded state, the elastic member is in an energy storage state; When the multiple-adaptive mechanism is out of the limiting space, the elastic member releases its elasticity, prompting the connecting rod mechanism to push the outer rod to rotate along the hinge point, so that the multiple-adaptive mechanism is in an expanded state, the surface support portion provides surface support force, and / or the three-dimensional support portion provides three-dimensional support force, driving the hemostatic fiber membrane to fit different types of wounds.
[0007] As one of the preferred solutions, the connecting rod mechanism includes a first connecting rod group and a second connecting rod group; wherein, One end of the first connecting rod group is slidably hinged on the central rod, and the other end is hinged to the second connecting rod group; One end of the second connecting rod group is hinged to the central rod, and the other end is hinged to each of the peripheral rods.
[0008] As one of the preferred solutions, the connecting rod mechanism includes a first connecting rod group and a second connecting rod group; wherein, One end of the first connecting rod group is slidably hinged on the central rod, and the other end is hinged to the second connecting rod group; One end of the second connecting rod group is hinged to the central rod, and the other end is hinged to each of the peripheral rods.
[0009] As one of the preferred solutions, the number of connecting rods in the second connecting rod group is in a one-to-one relationship or a many-to-one relationship with the number of connecting rods in the first connecting rod group.
[0010] As one of the preferred solutions, the ends of some of the peripheral rods are also hinged to the ends of the central rod.
[0011] As one of the preferred solutions, the first connecting rod group and the second connecting rod group are both in an inverted V shape as a whole, the surface supporting portion is in a V shape as a whole, and the three are respectively arranged along the central rod from top to bottom with intervals.
[0012] As one of the preferred solutions, the energy storage state includes a compression state or a tension state; When in the stretched state, two ends of the elastic member are connected to the first connecting rod group and the second connecting rod group respectively; When in the compressed state, two ends of the elastic member are connected to the central rod and the first connecting rod group respectively; Wherein, the elastic member is a spring, and the spring is sleeved on the outer circumference of the central rod.
[0013] As one of the preferred solutions, the hemostatic fiber membrane is composited by polyvinyl alcohol and chitosan through electrostatic spinning technology.
[0014] As one of the preferred schemes, the boosting mechanism includes a push cylinder, a push rod and a push cap. The push cylinder is hollow inside the openings at both ends to form the limiting space. The push rod extends from one end opening into the limiting space to flexibly contact with the multiple adaptation mechanism, and the push cap seals the other end opening.
[0015] As one of the preferred solutions, a touch rod is provided at one end of the central rod away from the peripheral rods, and the touch rod is in contact with the push rod.
[0016] The second aspect of the present invention also provides an application method of the rapid hemostasis structure based on multiple adaptations, the method comprising: The multi-adaptive mechanism with the hemostatic fiber membrane is folded and sealed into the limited space of the boosting mechanism; Opening the push cap of the boosting mechanism and pushing the push rod of the boosting mechanism to separate the multi-adaptive mechanism with the hemostatic fiber membrane from the limiting space; The elastic parts of the multi-adaptive mechanism in the folded state release their elasticity, prompting the connecting rod mechanism to push the outer rod to rotate along the hinge point, thereby unfolding the multi-adaptive mechanism. The surface support part provides surface support force, and / or the three-dimensional support part provides three-dimensional support force, driving the hemostatic fiber membrane to fit different types of wounds.
[0017] Compared with the prior art, this application has the following advantages: The present invention proposes a rapid hemostasis structure based on multiple adaptations, including: a boosting mechanism, which is provided with a limiting space inside; a multiple adaptation mechanism, which is built into the limiting space and is in a folded state in the limiting space; wherein the multiple adaptation mechanism includes: a surface support portion, which has at least two outer rods, and a plurality of the outer rods enclose a surface area, and a hemostatic fiber membrane is arranged on the surface area; a three-dimensional support portion, which includes a central rod and a connecting rod mechanism, and the connecting rod mechanism is respectively hinged to the central rod and the outer rod to form a three-dimensional area; an elastic member, which is connected to the connecting rod mechanism, and the elastic member is in an energy storage state in the folded state; when the multiple adaptation mechanism is separated from the limiting space, the elastic member releases its elasticity, prompting the connecting rod mechanism to push the outer rod to rotate along the hinge point, so that the multiple adaptation mechanism is in an unfolded state, the surface support portion provides a surface support force, and / or the three-dimensional support portion provides a three-dimensional support force, driving the hemostatic fiber membrane to fit different types of wounds.
[0018] By adopting the technical solution of the present application, for superficial wounds, the rotation and expansion of the peripheral rods provide sufficient surface support force, which can stretch the attached hemostatic fiber membrane. At the same time, the tension of the elastic member keeps the hemostatic fiber membrane at a certain tension, so that the hemostatic fiber membrane is fully stretched and covers the wound surface. The hemostatic fiber membrane prevents the spread of exudate and promotes coagulation. For deep wounds or penetrating wounds, the rotation and expansion of the connecting rod mechanism provides sufficient three-dimensional support force, which together with the central rod and the peripheral rods form an umbrella-shaped three-dimensional support structure with effective three-dimensional support, covers deeper wounds, and ensures that the hemostatic fiber membrane can penetrate into the wound and adhere to the inner wall to stop bleeding.
[0019] Therefore, the hemostatic structure can quickly and effectively deal with penetrating wounds, and can adapt to superficial wounds. The multiple adaptive mechanisms have significant adaptability and versatility, can be adaptively deployed in different situations, and provide effective hemostatic solutions for different types of trauma. In actual applications, it can cope with a wider range of wound types and has obvious innovation and practical value.

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0025] It should be noted that wounds are usually classified according to the cause of injury, depth, shape, and infection status. Among them, the depth of the wound is usually divided into superficial wounds, deep wounds, and penetrating wounds. The shapes of wounds of different depths are also different. For example, complex environments such as battlefields, disaster relief, traffic accidents, and industrial accidents can cause various types of trauma. For multiple types of wounds in these complex environments, it is often necessary to have extremely high adaptability. It requires not only the ability to adjust according to the shape and depth of the wound to ensure full coverage of the wound surface, but also to provide accurate hemostatic coverage for both superficial wounds and deeper wounds.
[0026] In addition, especially in high-pressure environments such as battlefields or traffic accidents, medical staff need fast and simple hemostatic tools to control bleeding and stabilize the patient's vital signs in the shortest possible time. Therefore, the application of hemostatic devices should be simple and easy to use so that they can be quickly applied in emergency situations.
[0027] However, although the existing hemostatic devices have improved adaptability to a certain extent, they can only be adaptively adjusted according to the shape of the wound. However, their structure is complex and requires many active nodes, which increases mechanical resistance, thus causing problems such as slow deployment speed and uneven deployment.
[0028] In addition, the hemostatic device for penetrating injuries cannot be used for superficial wounds because it does not have surface support. The hemostatic device for superficial injuries does not have three-dimensional support, so it is difficult to effectively fill and stop bleeding when dealing with penetrating injuries because it lacks the ability to expand in three dimensions. Therefore, the existing hemostatic devices cannot provide effective hemostatic solutions for different types of trauma, so their target of action is narrow, their adaptability is weak, and they cannot meet the multi-functional needs of multiple types of wounds in complex environments.
[0029] Therefore, it is of great significance to develop a hemostatic device that has multiple advantages such as fast deployment speed, multiple adaptability, and easy operation.
[0030] Reference Figure 1-Figure 3 As shown, Figure 1 This is a schematic diagram of the overall structure of the rapid hemostasis structure based on multiple adaptations shown in the present invention; Figure 2 is an overall structural diagram of the multiple adaptation mechanism shown in the present invention in a folded state; Figure 3It is an overall structural diagram of the multiple adaptation mechanism in the unfolded state shown in the present invention. The present invention provides a rapid hemostasis structure based on multiple adaptations, including: a boosting mechanism, which is provided with a limiting space inside; a multiple adaptation mechanism, which is built into the limiting space and is in a folded state in the limiting space; wherein the multiple adaptation mechanism includes: a surface support portion, which has at least two peripheral rods 5, and a plurality of the peripheral rods 5 enclose a surface area, and a hemostatic fiber membrane is provided on the surface area; a three-dimensional support portion, which includes a central rod 3 and a connecting rod mechanism 4, and the connecting rod mechanism 4 is respectively hinged to the central rod 3 and the peripheral rod 5 to form a three-dimensional area; an elastic member, which is connected to the connecting rod mechanism 4, and the elastic member is in an energy storage state in the folded state; When the multiple-adaptive mechanism is out of the limiting space, the elastic member releases its elasticity, prompting the connecting rod mechanism 4 to push the outer rod 5 to rotate along the hinge point, so that the multiple-adaptive mechanism is in an unfolded state, the surface support portion provides surface support force, and / or the three-dimensional support portion provides three-dimensional support force, driving the hemostatic fiber membrane to fit different types of wounds.
[0031] Specifically, the boosting mechanism in this embodiment is used as a functional part to push the multi-adaptive mechanism from the folded state to the inside / surface of different types of wounds to unfold it. Before unfolding, a limited space is provided inside the boosting mechanism to limit the range of movement of the multi-adaptive mechanism, facilitate storage and transportation, and ensure that it remains in a compact folded state when not in use. When it is needed, the multi-adaptive mechanism is separated from the limited space, and the multi-adaptive mechanism will automatically unfold along a predetermined trajectory as pushed by the boosting mechanism, switching from the folded state to the unfolded state.
[0032] Specifically, the multiple adaptive mechanisms can be adaptively deployed to stop bleeding according to different types of wounds. The surface support part and the three-dimensional support part can provide surface support force and three-dimensional support force respectively, ensuring that the device can adapt to superficial injuries and penetrating injuries. Among them, the surface support part is provided with multiple peripheral rods 5, and the multiple peripheral rods 5 form a surface area. This surface area can be similar to the structure of an umbrella surface, which can provide a plane support when deployed.
[0033] The hemostatic fiber membrane is attached to the surface area and can directly fit the wound surface with the surface area. The hemostatic fiber membrane has the ability to absorb exudate and promote blood coagulation, thus playing a hemostatic function. Therefore, when the peripheral rod 5 is unfolded, the surface area is expanded, and the hemostatic fiber membrane is unfolded and closely covers the wound, providing surface support, so that the device can closely fit the superficial wound.
[0034] According to different application requirements and design goals, the peripheral rods 5 can adopt various design forms. For example, the shapes, sizes and arrangement of the plurality of peripheral rods 5 can be selected in a wide range, and the surface area formed by them becomes larger and the surface support force becomes larger after being unfolded.
[0035] In some embodiments, the peripheral rod 5 is straight.
[0036] In some embodiments, the peripheral rod 5 has a certain curvature, and is in the shape of an arc, a wave line, or other curves.
[0037] In some embodiments, the outer rod 5 can adopt a foldable design, similar to the rod structure of the umbrella surface, that is, a foldable hinge point is designed at a certain node to form an overlapping V-shape, which can bend in the folded state and straighten step by step like an umbrella surface when unfolded.
[0038] In some embodiments, the peripheral rod 5 can be made of elastic and flexible material, which can bend or deform in a folded state and restore its rigidity to serve as a support member when unfolded.
[0039] In some embodiments, the shapes of the plurality of peripheral rods 5 may be partially or entirely the same.
[0040] In some embodiments, the plurality of peripheral rods 5 are arranged radially or annularly.
[0041] In some embodiments, a plurality of peripheral rods 5 are cross-designed to form a mesh or grid structure.
[0042] In some embodiments, multiple peripheral stems are radially distributed to form a layered support region.
[0043] Exemplarily, a plurality of peripheral rods 5 radiate outward from the central rod 3 and are of double-layer design, forming a structure similar to an umbrella frame.
[0044] Exemplarily, a plurality of peripheral rods 5 form a nearly circular ring to form a stable surface area.
[0045] Exemplarily, a plurality of peripheral rods 5 form a grid-like surface, forming a surface structure with a larger contact surface with the hemostatic fiber membrane. Preferably, multiple outer rods 5 are spaced apart and extend obliquely, and at least two of them enclose an arc-shaped surface area. The angle of the outer rods 5 after expansion becomes larger but is not parallel to the horizontal plane. The hemostatic fiber membrane becomes larger in an umbrella-shaped structure on the surface area. That is to say, the outer edge contour of the surface area has a three-dimensional sense, which can improve the overall supporting effect. When the overall deformation is attached to the superficial wound, it is not easy to deform or collapse due to external force or tissue displacement, ensuring that the hemostatic fiber membrane can continuously cover and stably support the target area.
[0046] Among them, the connecting rod mechanism 4 of the three-dimensional support part connects the central rod 3 and the peripheral rod 5 together through the hinge point to form a three-dimensional structure. Among them, the central rod 3 supports the movement of the connecting rod mechanism 4 and itself is fixed. When the connecting rod mechanism 4 is unfolded, not only will the peripheral rod 5 expand radially to continue to increase the surface support force, but the connecting rod mechanism 4 will continue to expand radially and axially to provide three-dimensional support force. Therefore, for penetrating wounds or deep wounds, the three-dimensional expansion of the connecting rod mechanism 4 and the peripheral rod 5 ensures that the hemostatic fiber can penetrate deep into the wound. After expansion, an internal support frame is formed to prop up the wound and ensure that the hemostatic fiber membrane fits tightly inside the wound, covering the deep area of the wound, thereby effectively absorbing wound exudate and helping blood coagulation.
[0047] In order to achieve rapid deployment, an elastic member is provided to provide deployment power. In the folded state, the elastic member is in a state of storing potential energy. When the multiple adaptation mechanisms are out of the limited space, the elastic member releases the potential energy, pushing the connecting rod mechanism 4 and the peripheral rod 5 to automatically deploy, thereby adapting to wounds of different depths and shapes.
[0048] In summary, when the boost mechanism pushes the multi-adaptive mechanism out of the limited space, the elastic member begins to release elastic potential energy. Since the elastic member is connected to the connecting rod mechanism 4, and the connecting rod mechanism 4 is hinged to the central rod 3, the elastic member pushes the connecting rod mechanism 4 to rotate and unfold around the hinge point with the central rod 3, so the angle of the connecting rod mechanism 4 increases; and since the peripheral rod 5 is hinged to the connecting rod mechanism 4, the connecting rod mechanism 4 drives the angle of the peripheral rod 5 to increase as the angle increases, and the peripheral rod 5 rotates and unfolds around the hinge point with the connecting rod mechanism 4, and the surface area expands.
[0049] In this way, by designing the surface support part and the three-dimensional support part, it can be quickly unfolded, and the unfolded hemostatic fiber membrane covers a large area, ensuring that wounds of different depths and sizes and shapes can be effectively covered and hemostatic.
[0050] For superficial wounds, the rotation and expansion of the peripheral rod 5 provides sufficient surface support force, which can stretch the attached hemostatic fiber membrane. At the same time, the tension of the elastic member keeps the hemostatic fiber membrane at a certain tension, so that the hemostatic fiber membrane is fully stretched and covers the wound surface. The hemostatic fiber membrane prevents the spread of exudate and promotes blood coagulation. For deep wounds or penetrating wounds, the rotation and expansion of the connecting rod mechanism 4 provides sufficient three-dimensional support force. It forms an umbrella-shaped three-dimensional support structure together with the central rod 3 and the peripheral rod 5, which has effective three-dimensional support, covers deeper wounds, and ensures that the hemostatic fiber membrane can penetrate into the wound and adhere to the inner wall to stop bleeding. Therefore, the hemostatic structure can quickly and effectively deal with penetrating wounds, and can adapt to superficial wounds. The multiple adaptive mechanisms have significant adaptability and versatility, can be adaptively expanded in different situations, and provide effective hemostatic solutions for different types of trauma. In practical applications, it can cope with a wider range of wound types and has obvious innovation and practical value.
[0051] It is understandable that for superficial wounds, the surface support part can be designed to play a major role to ensure that the surface area covers the wound, but the three-dimensional support part has a smaller three-dimensional expansion range to prevent the three-dimensional support structure from protruding too much. When penetrating the wound, the three-dimensional support part can be designed to have a larger expansion range to extend deep into the wound to form a three-dimensional support.
[0052] It can also be known that the expansion ratio of the surface support part and the three-dimensional support part in different situations can be controlled by adjusting various parameters such as the preload force and stroke range of the elastic part, the length and hinge angle of the outer rod 5 and the connecting rod mechanism 4, the hinge position, the rotation range of the hinge point, etc., so that different expansion effects can be achieved for superficial wounds and penetrating wounds.
[0053] As a further explanation of this embodiment, the connecting rod mechanism 4 includes a first connecting rod group 41 and a second connecting rod group 42; wherein, one end of the first connecting rod group 41 is slidably hinged on the central rod 3, and the other end is hinged to the second connecting rod group 42; one end of the second connecting rod group 42 is hinged to the central rod 3, and the other end is hinged to each of the peripheral rods 5.
[0054] Specifically, the center rod 3 is a vertical rod, which coincides with the center line of the link mechanism 4. The first link group 41 and the second link group 42 are symmetrical relative to the center rod 3, and the first link group 41 is located above the second link group 42. The first link group 41 is slidably hinged on the center rod 3, so the first link group 41 can not only rotate during the deployment process, but also slide within a certain range on the center rod 3. The other end of the first link group 41 is hinged to the second link group 42.
[0055] Therefore, when the first link group 41 slides downward under the push of the elastic member, the central rod 3 is similar to the umbrella handle, the second link group 42 and the peripheral rod 5 are hinged to each other and are similar to the ribs of the umbrella, and the hemostatic fiber membrane is similar to the umbrella surface. The first link group 41 is driven by the elastic member and is similar to the thrust provided by the manual opening of the umbrella. Under the elastic force, the first link group 41 gradually slides and unfolds, driving the second link group 42 to rotate and unfold around the hinge point of the central rod 3, and the second link group 42 continues to drive the peripheral rod 5 to rotate and unfold, and open the hemostatic fiber membrane, which is similar to the umbrella opening process and principle. Therefore, this design can be used quickly in emergency situations such as the umbrella opening process, and the overall design is simple, with fewer mechanical parts and fewer hinge points, so it is more suitable for large-scale production and rapid application.
[0056] Among them, the outer rods 5 can be arranged in a circular array with uniform intervals to form an umbrella-shaped structure, so that the outer rods 5 can maintain uniform tension of the hemostatic fiber membrane when unfolded, avoiding wrinkles or irregular folds, thereby ensuring that the hemostatic fiber membrane can quickly, smoothly and evenly cover the area that is bleeding or needs support.
[0057] Correspondingly, the second link group 42 is also composed of a plurality of second link groups 42 , and each second link is hinged to each peripheral rod 5 .
[0058] In some embodiments, the number of links in the second link group 42 is in a one-to-one relationship with the number of links in the first link group 41. Accordingly, the first link group 41 can be composed of multiple first link groups 41, and each first link is hinged to each second link in a one-to-one correspondence. Therefore, when the elastic member pushes the first link group 41 to slide along the central rod 3, each first link drives each second link to unfold, and each second link drives each peripheral rod 5 to unfold.
[0059] In some embodiments, the number of connecting rods in the second connecting rod group 42 is in a many-to-one relationship with the number of connecting rods in the first connecting rod group 41. In this embodiment, the second connecting rod corresponds to the peripheral rod 5 one by one, but the number of first connecting rods can be less than the number of second connecting rods. That is, the two ends of part of the second connecting rod are respectively hinged to the central rod 3 and the peripheral rod 5, and the rod body is hinged to the first connecting rod. The two ends of the remaining second connecting rod are respectively hinged to the central rod 3 and the peripheral rod 5, and the rod body is not hinged to the first connecting rod. Therefore, when the first connecting rod drives part of the second connecting rod to unfold, due to the tension of the hemostatic fiber membrane, the remaining second connecting rod can be unfolded accordingly, so fewer first connecting rods can be used to drive the unfolding of the entire system, reducing the complexity of the structure and the manufacturing cost, while balancing the pressure distribution. At the same time, reducing the number of first connecting rods can also reduce the overall weight and improve the portability of the system.
[0060] Preferably, two first connecting rods and two second connecting rods are provided. The first connecting rod group 41 and the second connecting rod group 42 are both in an inverted V shape as a whole, the surface support portion is in a V shape as a whole, and the three are spaced from top to bottom along the center rod 3. In this embodiment, the combination of the inverted V shape and the V shape enables the structure to provide surface support force when it is unfolded, and the axial double inverted V shape can form a stable three-dimensional support force, thereby enhancing the stability and adaptability of the structure. Compared with a complex unfolding structure, the geometric shape is simpler and the unfolding speed is faster, which is suitable for rapid application in emergency situations, reduces the burden on medical staff, and the operation process is simple and intuitive, suitable for various medical environments.
[0061] Furthermore, the ends of some of the peripheral rods 5 are respectively hinged to the ends of the central rod 3. In this embodiment, the plurality of peripheral rods 5 of the surface support portion may include an outermost edge peripheral rod 51 and an inner central peripheral rod 52. Figure 2 As shown, only the edge peripheral rod 51 may be hinged to the second rod, and the hemostatic fiber membrane may be covered on the edge peripheral rod 51 , and the edge peripheral rod 51 may open the hemostatic fiber membrane.
[0062] Furthermore, an edge peripheral rod 51 and a center peripheral rod 52 may be provided simultaneously, one end of the center peripheral rod 52 being hinged to the second connecting rod and the other end being hinged to the center rod 3, so that the surface support portion forms a radial double V-shaped structure (the connecting line of the edge peripheral rod 51 is V-shaped).
[0063] In combination with the above embodiments, the closed end of the V-shaped edge peripheral rod 51 is hinged at the bottom end of the center rod 3, and the opening faces upward. Therefore, when the end of the center peripheral rod 52 is hinged to the center rod 3, the driving force applied to the second connecting rod not only causes the edge peripheral rod 51 to rotate along the second connecting rod, but also causes the center peripheral rod 52 to rotate along the center rod 3, forming a structure similar to a complete umbrella surface, thereby enhancing the overall stability. When the second connecting rod pushes all the peripheral rods 5 to rotate outward and unfold, a certain relative position is maintained to prevent the peripheral rods 5 from being deformed or unstable when subjected to external forces.
[0064] In some embodiments, the number of edge peripheral rods 51 and center peripheral rods 52 may be the same or different.
[0065] Further, the energy storage state includes a compression state or a tension state; When in the stretched state, two ends of the elastic member are connected to the first connecting rod group 41 and the second connecting rod group 42 respectively; When in the compressed state, the two ends of the elastic member are connected to the central rod 3 and the first connecting rod group 41 respectively; The elastic member is a spring 2 , and the spring 2 is sleeved on the outer circumference of the central rod 3 .
[0066] In this embodiment, in the compressed state, the spring 2 is compressed to store mechanical energy. At this time, the two ends of the spring 2 are respectively connected to the top of the center rod 3 and the inverted V-shaped closed end of the first connecting rod group 41. When the multiple adaptation mechanism is out of the limited space, the spring 2 provides a driving force to push the first connecting rod group 41 to slide downward along the center rod 3. Since the rod length of the first connecting rod group 41 remains unchanged, it will give a driving force to the second connecting rod group 42, and the second connecting rod group 42 and the peripheral rod 5 hinged to the second connecting rod group 42 are unfolded together similar to the structure and mechanism of the umbrella ribs.
[0067] In the stretched state, the spring 2 is stretched to store mechanical energy. At this time, the two ends of the spring 2 are respectively connected to the closed end of the inverted V shape of the first link group 41 and the closed end of the inverted V shape of the second link group 42, and are located in the inverted V-shaped opening of the first link group 41. When the multiple adaptation mechanism is out of the limited space, the spring 2 provides a pulling force to pull the first link group 41 to slide downward along the central rod 3. Since the rod length of the first link group 41 remains unchanged, it will give a driving force to the second link group 42, and the second link group 42 and the peripheral rod 5 hinged to the second link group 42 are unfolded together similar to the umbrella rib structure and principle.
[0068] Therefore, the structural design of this embodiment is simple and easy to adjust. By connecting elastic parts at different positions, a flexible energy storage and transmission mechanism is provided. It has fewer mechanical parts and fewer hinge points, and is more suitable for large-scale production and rapid application.
[0069] In a further technical solution, the hemostatic fiber membrane is composited by polyvinyl alcohol and chitosan through electrospinning technology. In this solution, the hemostatic fiber membrane is composited by polyvinyl alcohol and chitosan through electrospinning technology, and the mass ratio of polyvinyl alcohol to chitosan is 8:2. The hemostatic fiber membrane has excellent biocompatibility and liquid absorption capacity. This material can quickly absorb wound exudate and promote blood coagulation.
[0070] like Figure 4 As shown, Figure 4 : is an exploded view of the boost mechanism, wherein a is a push tube 7, b is a push rod 6, and c is a push cap 8. In a further technical solution, the boost mechanism comprises a push tube 7, a push rod 6 and a push cap 8, the push tube 7 has two openings at both ends and the interior is hollow to form the limit space, the push rod 6 extends from one end opening into the limit space to movably contact with the multi-adaptive mechanism, and the push cap 8 seals the other end opening.
[0071] In the present solution, the push tube 7 is used to store and transport the multi-adaptive mechanism with the hemostatic fiber membrane. The design of the push tube 7 is ergonomic and easy to hold and operate. It is made of transparent material, which is convenient for observing the state of the internal material and ensuring that the integrity of the material can be checked before use. The push rod 6 is used to push the multi-adaptive mechanism with the hemostatic fiber membrane to ensure that it enters the wound smoothly. The design of the push rod 6 is ergonomic and easy to operate, reducing the fatigue of medical staff. Among them, the length and diameter of the push rod 6 can be accurately calculated to ensure that sufficient thrust can be provided during use. The push cap 8 protects the opening of the push tube 7 to prevent external contaminants from entering the push tube 7, and the push cap 8 is designed to be sterile before use and easy to disassemble.
[0072] As an improvement of this embodiment, the end of the central rod 3 away from the peripheral rod 5 is provided with a feeler rod 1, and the feeler rod 1 contacts the push rod 6. In combination with the above embodiments, the feeler rod 1 is provided at the top of the central rod 3, contacts the push rod 6, and the first connecting rod group 41, the second connecting rod group 42 and the peripheral rod 5 are sequentially provided at the top from the bottom, and the central peripheral rod 52 is provided at the bottom of the central rod 3. When the push rod 6 applies a thrust, the thrust can be directly transmitted to the feeler rod 1.
[0073] When not in use, the push rod 6 is in a non-pushed state, the feeler rod 1 is in static contact with the push rod 6, and the entire multi-adaptive mechanism remains in a folded state and is in the limited space (push tube 7). When in use, when the push rod 6 is pushed, the force is transmitted to the feeler rod 1, effectively pushing the center rod 3 to move outward along the axial direction of the push tube 7 and quickly enter the wound. Therefore, the design of the feeler rod 1 simplifies the operation steps, and the user only needs to apply force lightly through the push rod 6 to quickly start the deployment mechanism. Especially in emergency situations, it can shorten the boost time and improve the emergency response efficiency of the device, which is suitable for various complex trauma treatment scenarios.
[0074] Another aspect of the present invention is to provide an application method of a rapid hemostasis structure based on multiple adaptations, the method comprising the following steps: S1. Fold the multi-adaptive mechanism with the hemostatic fiber membrane and seal it in the limited space of the boosting mechanism; S2, opening the push cap 8 of the boosting mechanism, pushing the push rod 6 of the boosting mechanism, and separating the multi-adaptive mechanism with the hemostatic fiber membrane from the limiting space; S3. The elastic parts of the multi-adaptive mechanism in the folded state release their elasticity, prompting the connecting rod mechanism 4 to push the outer rod 5 to rotate along the hinge point, thereby unfolding the multi-adaptive mechanism. The surface support part provides surface support force, and / or the three-dimensional support part provides three-dimensional support force, driving the hemostatic fiber membrane to fit different types of wounds.
[0075] Specifically, first ensure that the hemostatic fiber membrane and the multi-adaptive mechanism are correctly filled in the push tube 7, and check the integrity of the device. Ensure that the booster mechanism and all components are in a sterile state. Check whether the push cap 8 of the push tube 7 and the push rod 6 seat are in a locked state to prevent accidental release.
[0076] When used specifically: Remove the push cap 8 to open the opening of the push cylinder 7.
[0077] Push the push rod 6 to fill the wound with the multiple adaptation mechanism with the hemostatic fiber membrane. The push of the push rod 6 should be stable to ensure that the hemostatic material can smoothly enter the wound.
[0078] The multiple adaptive mechanisms automatically unfold after releasing elastic potential energy, driving the hemostatic fiber membrane to fit the wound surface and achieve rapid hemostasis. The state of the hemostatic fiber membrane should be observed during the unfolding process to ensure that it is stably unfolded in the wound. Combining the hemostatic and fluid absorption capabilities of the hemostatic fiber membrane with the pressure distribution and support effect of the multiple adaptive mechanisms, efficient hemostasis is achieved, bleeding time is reduced, and the hemostasis process is rapid, which can control bleeding in a short time.
[0079] Therefore, the embodiment of the present invention provides an efficient and convenient hemostasis solution, which is particularly suitable for the treatment of complex wounds. The design of the device not only improves the hemostasis efficiency, but also enhances the safety and reliability of use. Through innovative materials and structural design, the present invention provides a new hemostasis tool for medical emergency and surgery, which has broad application prospects.
