[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention achieves stable fixation of the hemostatic device on the arm by fitting the arc plate 1 and the arc plate 2 components to the two sides of the human arm correspondingly, the arm shape is approximately elliptical, and inserting the two ends of the arc plate 2 into the slots opened at the two ends of the arc plate 1, which not only ensures the close fit of the device and the patient's arm, but also greatly improves the firmness of the fixation. Secondly, the fixing block in the present invention is connected to one end of the arc plate 2 and enters the slot together with the movement of the arc plate 2, and the special clamping block arranged inside the slot has a through groove on its surface and a component fixing spring arranged inside, and one end of the fixing spring is fixedly connected to the surface of the round rod, which effectively limits the free rotation of the clamping block, so that during the process of inserting the arc plate 2 into the slot, the clamping block can only swing in a specific direction, thereby ensuring that the fixing block and the arc plate 2 can be smoothly and stably inserted into the slot, further enhancing the stability of the device. Furthermore, when setting the arc plate 1 and the arc plate 2, the present invention fully considers the accuracy of the hemostatic position, and by measuring and fixing the position where hemostasis is required, so that the downward pressure The plate can be accurately aligned with the bleeding point, thereby improving the hemostasis efficiency. At the same time, the fixation of the arc plate one and the arc plate two also limits the random movement of the patient's forelimbs, helps to reduce the blood flow rate, and further improves the hemostasis effect. In addition, the present invention also has a convenient disassembly function. After the hemostasis is completed, you only need to simply press down the tail of the card block located on the outside to move the front end of the card block and the fixed block outward and separate them. Then, pull the arc plate two component outward to easily disassemble the hemostat. This design enables the hemostat to move with the patient's movement, which is more conducive to the patient's movement. Finally, the soft pad in the present invention fits the patient's skin surface, which not only increases the stability of the arc plate one and the arc plate two components and avoids sliding, but also the arc plate one and the arc plate two themselves have a certain degree of deformability, which can better adapt to arms of different shapes and sizes, ensuring the stability and reliability of the hemostasis effect. In summary, the hemostatic device provided by the present invention has significant beneficial effects such as stable fixation, high hemostasis efficiency, convenient disassembly and strong adaptability.

[0022] (2) The present invention achieves a close fit between the hemostatic device and the bleeding site of the patient by accurately aligning the lower pressure plate to the bleeding site of the patient and skillfully inserting the extrusion belt into the hollow plate, while ensuring that the surface of the extrusion belt connected to the positioning block is precisely aligned with the side of the thin rod installed in the hollow plate. This design not only improves the accuracy of hemostasis, but also ensures the maximum hemostasis effect. Secondly, in the process of pulling the extrusion belt to make its inner wall fit the patient's hemostasis site as much as possible, the present invention skillfully utilizes the cooperation between the positioning block and the hollow plate, as well as the tightening action of the extrusion belt at the moment of pulling out the needle, so that the lower pressure plate can be completely squeezed on the bleeding site, thereby effectively pressing the bleeding site and significantly reducing blood outflow. This innovative design significantly improves the hemostasis efficiency and reduces the patient's pain. Furthermore, the positioning spring in the present invention is firmly fixed inside the long groove, effectively limiting the rotation of the clamp, further enhancing the stability of the hemostatic device, and at the same time, The bottom end of the lower pressure plate fits tightly against the patient's skin, providing a certain friction force, preventing the hemostatic device from sliding during the hemostasis process; and the circular ring design connected to the top of the lower pressure plate can effectively disperse the pulling force on the lower pressure plate by moving the sliding rod inside the circular ring when the extrusion belt is twitching, further avoiding the movement of the hemostatic device and ensuring the continuity and stability of hemostasis. Finally, after hemostasis is completed, the hemostatic device provided by the present invention only needs to simply press up the tail of the card to easily separate the front end of the card from the positioning block, thereby quickly and easily removing the hemostat from the patient's forelimb. This operation process is simple and intuitive, and can even be completed with one hand, which greatly improves the patient's use experience, especially for patients who still retain a certain self-care ability, it is more practical and convenient. In summary, the hemostatic device of the present invention shows significant beneficial effects in terms of hemostasis accuracy, hemostasis efficiency, stability and ease of operation.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] See also Figure 1-Figure 6 As shown, an emergency forelimb hemostat, comprising:

[0033] The arc-shaped plate 1 is provided with an arc-shaped plate 2 on one side of the arc-shaped plate 1. The arc-shaped plate 1 is provided with a slot 4 at both ends. The slot 4 is provided with a placement slot 5 at the top and bottom. The slot 4 is provided with a fixing mechanism 6 in the middle. The fixing mechanism 6 includes a round rod 61. The round rod 61 is provided with a clamping block 63 in the middle. The clamping block 63 is provided with a round groove 64 in the middle. The inner wall of the round groove 64 is provided with two through grooves 65 in the middle. The middle of the round rod 61 is fixedly connected with two fixing springs 62. The fixing spring 62 is provided inside the round groove 64. One end of the fixing spring 62 passes through the corresponding through groove 65. The two ends of the round rod 61 are fixedly connected with the inner wall of the corresponding placement slot 5. The fixing mechanism 6 also includes two groups of fixing blocks 66. The bottom ends of the two groups of fixing blocks 66 are fixedly connected to the two ends of the arc-shaped plate 2, respectively. The two ends of the arc-shaped plate 2 are respectively embedded in the two slots 4.

[0034] The arc plate 1 and the arc plate 2 are respectively fitted to the two sides of the human arm, and the shape of the arm is similar to an ellipse. In the specific operation, the two ends of the arc plate 2 are inserted into the receiving space slot 4 opened at the two ends of the arc plate 1. At the same time, the fixing block 66 is connected to one end of the arc plate 2 and enters the space slot 4 together with the movement of the arc plate 2. Inside the placement slot 5, a specific structural block 63 is provided, and a through groove 65 is opened on its surface, and a fixing spring 62 is provided inside the through groove 65. One end of the fixing spring 62 is fixedly connected to the surface of another round rod 61. Such a design limits the free rotation of the block 63. When the arc plate 2 is inserted into the slot 4, the block 63 can only swing to the left, ensuring that the fixing block 66 and the arc plate 2 can be smoothly and stably inserted into the space slot 4, so that the arc plate 1 and the arc plate 2 are firmly fixed on the patient's arm in this way.

[0035] Before fixing arc plate 1 and arc plate 2, it is necessary to accurately measure the position where bleeding is required to ensure that the lower pressure plate 91 can be accurately aligned with the position after fixing. The purpose of designing arc plate 1 and arc plate 2 is to enable the hemostatic device to be more stably fixed on the patient's forelimbs, while also effectively limiting the random movement of the patient's forelimbs, thereby reducing blood flow rate and improving hemostasis efficiency.

[0036] After the hemostasis is completed, it is only necessary to press down the tail of the external clamping block 63 to move the front end of the clamping block 63 and the fixed block 66 outward and separate from the fixed block 66. Then, the arc plate 2 is pulled outward to move the fixed block 66 connected to one end thereof to the outside of the slot 4, so that the hemostat is easily disassembled. The design of the hemostat is flexible and can move with the movement of the patient, which greatly facilitates the patient's movement.

[0037] In addition, the soft pad 3 fits the patient's skin surface, which not only increases the stability of the components arc plate 1 and arc plate 2 2 and avoids sliding, but also the arc plate 1 and arc plate 2 2 themselves have a certain degree of deformability, which can better adapt to arms of different shapes and sizes, ensuring the stability and reliability of the hemostatic effect.

[0038] Embodiment 2:

[0039] refer to Figure 1-Figure 6As shown, the extrusion mechanism 8 is arranged on the back of the pressing mechanism 9 to fix the pressing mechanism 9; the extrusion mechanism 8 includes an extrusion belt 81, one end of the extrusion belt 81 is connected to a hollow plate 82, the middle part of the hollow plate 82 is provided with two fixing grooves 83, the inside of the fixing groove 83 is connected to a thin rod 84, the middle part of the thin rod 84 is sleeved with a positioning spring 87, the outside of the positioning spring 87 is provided with a clamping member 85, the middle part of the clamping member 85 is provided with a long groove 86, one end of the positioning spring 87 is fixedly connected to the outer wall of the thin rod 84, the other end of the positioning spring 87 is fixedly connected to the inner wall of the long groove 86, the other end of the extrusion belt 81 is connected to a plurality of positioning blocks 88, the clamping member 85 is engaged with the corresponding positioning blocks 88, the back side of the arc plate 1 is fixedly connected to a long rod 7, one end of the long rod 7 is fixedly connected to the front side of the extrusion belt 81, and one end of the extrusion belt 81 passes through the middle part of the hollow plate 82.

[0040] refer to Figure 6 , a pressing mechanism 9, which is arranged on the back of the arc plate 1 for stopping bleeding; the pressing mechanism 9 includes a pressing plate 91, a circular ring 92 is fixedly connected to the back of the pressing plate 91, fixing plates 93 are arranged on both sides of the circular ring 92, a sliding rod 94 is arranged between the two fixing plates 93, the back of the fixing plate 93 is fixedly connected to a side wall of the extrusion belt 81, the circular ring 92 is movably sleeved on the middle part of the sliding rod 94, and the middle parts of the arc plate 1 and the arc plate 2 are connected with a soft pad 3 for anti-slip.

[0041] In order to accurately apply the hemostatic device to the position where the patient needs to stop bleeding, we first ensure that the lower pressure plate 91 is accurately aligned with the bleeding point. Then, insert the extrusion belt 81 with one end connected to the positioning block 88 into the interior of the hollow plate 82, ensuring that the surface of the extrusion belt 81 connected to the positioning block 88 is accurately aligned with the side of the hollow plate 82 equipped with the thin rod 84. Then, push the positioning block 88 deep into the interior of the hollow plate 82, and gently pull the extrusion belt 81 along the penetration direction so that its inner wall fits tightly against the patient's hemostatic site. While pulling out the needle, tighten one end of the extrusion belt 81 connected to the positioning block 88 so that the extrusion belt 81 is tightly wrapped around the patient's bleeding site. At this time, the lower pressure plate 91 will completely cover and compress the bleeding port, effectively reducing blood outflow. At the same time, the positioning spring 87 is firmly installed inside the long groove 86, effectively limiting the rotation of the clamp 85.

[0042] Among them, the bottom of the lower pressure plate 91 fits tightly against the patient's skin, providing sufficient friction to prevent sliding, and the top is connected to the ring 92. When the squeezing belt 81 is pulled, the slide rod 94 moves inside the ring 92, effectively dispersing the pulling force on the lower pressure plate 91 and preventing the lower pressure plate 91 from shifting during the hemostasis process.

[0043] After hemostasis is completed, the front end of the clamp 85 can be easily separated from the positioning block 88 by simply pushing up the tail of the clamp 85, so that the hemostat can be quickly and easily removed from the patient's forelimb. The whole operation process is simple and intuitive, and can even be completed with one hand, which undoubtedly provides great convenience for patients who still retain a certain degree of self-care ability.
