[0080] It should be noted that the engagement of the driven gear 16 with the tooth groove 105 ensures the precise rotation of the first rolling rod 81 during the movement, thereby achieving precise control of the winding amount of the pressure belt 4; the design of the straight slide groove 104 and the movable plate 13 provides a stable movement path for the first rolling rod 81, reducing the adjustment error caused by shaking or offset; the first adjustment mechanism is designed inside the upper pressure block 1, which not only saves space but also maintains the overall aesthetics of the hemostatic device; the mechanical linkage design makes the adjustment process quick and continuous, thereby improving the efficiency of the hemostatic operation.

[0081] Furthermore, an air outlet hole 106 and an air vent 107 penetrating the upper pressing block 1 are provided on the inner wall of the adjusting groove 102. A one-way valve 17 is provided inside the air outlet hole 106. The one-way valve 17 allows the adjusting groove 102 to be unidirectionally conducted to the outside of the upper pressing block 1. A pressure relief valve stem 18 is provided at the outer end of the air vent 107.

[0082] It should be understood that, based on the above-mentioned characteristic definition, the air outlet 106 is a hole opened on the inner wall of the regulating tank 102 and passing through the upper pressing block 1, which is used for gas to flow from the inside of the regulating tank 102 to the outside; the one-way valve 17 is installed inside the air outlet 106, and its function is to ensure that the gas can only flow in one direction, that is, from the regulating tank 102 to the outside of the upper pressing block 1, to prevent external gas or liquid from flowing back into the regulating tank 102; this provides a safe exhaust channel during the regulation process, especially when the internal air pressure increases, to prevent structural damage or user injury caused by excessive air pressure. ; The air vent 107 is also a hole opened on the inner wall of the regulating tank 102, but unlike the air outlet 106, it is mainly used to actively release the gas pressure in the regulating tank 102 when needed; the pressure relief valve stem 18 is set at the outer end of the air vent 107, and the user can control the opening and closing of the air vent 107 by operating the pressure relief valve stem 18; when the internal air pressure of the regulating tank 102 rises abnormally and needs to be quickly relieved, the user can manually open the pressure relief valve stem 18 to allow the gas to be quickly discharged through the air vent 107, thereby reducing the internal air pressure and protecting the safety of the equipment and users.

[0083] It should be noted that the design of the one-way valve 17 and the pressure relief valve stem 18 provides double safety protection for the adjustment mechanism. When the first adjustment mechanism is in action, it can balance the air pressure inside the upper pressure block, effectively preventing dangerous situations caused by excessive internal air pressure. The user can actively control the air pressure in the adjustment groove 102 by operating the pressure relief valve stem 18 as needed, thereby increasing the operational flexibility and adaptability of the equipment. The one-way valve 17 and the pressure relief valve stem 18 are both detachable and replaceable components, which are convenient for inspection and replacement during equipment maintenance. By releasing the internal air pressure in time, the damage to the equipment structure and components caused by excessive air pressure can be reduced, thereby extending the service life of the equipment. The safe, reliable and easy-to-operate design improves the user's overall satisfaction and usage experience with the hemostatic device.

[0084] Furthermore, a hydraulic chamber 202 is provided in the middle position of the lower pressing block 2, and hydraulic oil is contained in the hydraulic chamber 202, and second winding grooves 201 are provided at both ends of the lower pressing block 2; the second adjusting mechanism includes a slider 21, a screw 19 and a second adjusting component; wherein the slider 21 is slidably provided at the opening of the hydraulic chamber 202; one end of the screw 19 is rotatably connected to the slider 21, and the other end is located outside the lower pressing block 2, and the position of the slider 21 is adjusted by rotating the screw 19, thereby adjusting the volume of the hydraulic chamber 202; the second adjusting component is symmetrically arranged in the second winding grooves 201 at both ends of the lower pressing block 2; a connecting hole 205 is provided at the bottom of the hydraulic chamber 202, and the hydraulic chamber 202 is connected to the second adjusting component through the connecting hole 205.

[0085] It should be understood that, based on the above-mentioned feature definition, the second adjustment mechanism is designed inside the lower pressing block 2, and the hydraulic pressure inside the hydraulic chamber 202 is changed by adjusting the volume thereof, and the second adjustment component in the second winding groove 201 is driven to work by this pressure change;

[0086] Specifically, the hydraulic chamber 202 is filled with hydraulic oil, which is the basis for realizing hydraulic transmission; the slider 21 is slidably arranged at the opening of the hydraulic chamber 202, and the slider 21 can be driven to move in the hydraulic chamber 202 by rotating the screw 19; when the screw 19 rotates, its axial movement will be converted into radial movement of the slider 21, thereby changing the effective volume of the hydraulic chamber 202; the reduction in the volume of the hydraulic chamber 202 will lead to the compression of the internal hydraulic oil, thereby generating hydraulic pressure; conversely, the increase in volume releases the pressure; the connecting hole 205 arranged at the bottom of the hydraulic chamber 202 is a channel for transmitting hydraulic pressure; when the pressure in the hydraulic chamber 202 changes, this pressure will be transmitted to the second adjusting component in the second winding groove 201 through the connecting hole 205; the second adjusting component is symmetrically arranged in the second winding groove 201 at both ends of the lower pressure block 2, because the second adjusting component is connected to the hydraulic chamber 202 through the connecting hole 205, when the pressure in the hydraulic chamber 202 changes, the second adjusting component will be subjected to the corresponding hydraulic pressure, thereby driving it to work.

[0087] It should be noted that the volume of the hydraulic chamber 202 is accurately adjusted by rotating the screw 19, thereby achieving precise control of the hydraulic pressure, making the operation of the second adjusting component more accurate and reliable; hydraulic transmission has the advantages of large power transmission and smooth transmission, and can ensure that the second adjusting component responds quickly and works stably after receiving the hydraulic pressure; all adjustment mechanisms are designed inside the lower pressure block 2, which not only saves space but also maintains the overall aesthetics of the hemostatic device; the structure of the hydraulic chamber 202 and the second adjusting component is relatively simple, and the connection between the components is clear, which is convenient for inspection and replacement during equipment maintenance; the automatic winding and release of the pressure belt is realized through hydraulic transmission, which improves the convenience and efficiency of the hemostatic operation and enhances the user experience.

[0088] Furthermore, a rotation groove 203 is symmetrically opened at the front and rear ends of the second winding groove 201 with the second winding groove 201 as the center, and an arc-shaped slide groove 204 is opened at one end of the rotation groove 203 close to the hydraulic chamber 202. The rotation groove 203, the arc-shaped slide groove 204 and the hydraulic chamber 202 are connected through a connecting hole 205; the second adjustment component includes a second winding rod 82, a ratchet 22, an arc block 23, a pawl 24 and an adjustment shaft 20; wherein the second winding rod 82 is rotatably arranged at In the second winding groove 201, both ends of the second rolling rod 82 pass through the rotating groove 203, and the pressing belt 4 is connected to the surface of the second rolling rod 82; the ratchet 22 is arranged in the rotating groove 203, and the ratchet 22 is sleeved on the second rolling rod 82; the arc block 23 is slidably arranged in the arc sliding groove 204; the pawl 24 is arranged at one end of the arc block 23 close to the ratchet 22, and the pawl 24 is engaged with the ratchet 22; the adjusting shaft 20 is rotatably arranged on the surface of the lower pressure block 2, and the adjusting shaft 20 is fixedly connected to one end of the second rolling rod 82.

[0089] It should be understood that, based on the above-mentioned feature definition, the second adjustment component is designed in the second winding groove 201 inside the lower pressure block 2 and the rotating groove 203 and arc-shaped slide groove 204 around it, and the winding and releasing of the pressure belt 4 are realized through the cooperation of hydraulic transmission and mechanical structure.

[0090] Specifically, when the hydraulic pressure in the hydraulic chamber 202 is transmitted to the rotating groove 203 and the arc-shaped slide groove 204 through the connecting hole 205, these pressures will act on various components of the second adjustment component; the second reel 82 is rotatably arranged in the second reeling groove 201, and the pressure belt 4 is connected to the surface of the second reel 82, so the rotation of the second reel 82 will drive the reeling or releasing of the pressure belt 4; the ratchet 22 is sleeved on the second reel 82 and is located in the rotating groove 203; the design of the ratchet 22 allows it to be driven to rotate in only one direction; when the ratchet 22 rotates in the driven direction, it can drive the second reel 82 to rotate, thereby contracting the pressure belt 4 and increasing the pressure on the puncture site; the arc block 23 is slidably arranged in the arc-shaped slide groove 204, and when the arc block 23 moves in the arc-shaped slide groove 204, the ratchet 24 thereon will move accordingly, and at this time, the ratchet 24 can be reversely fine-tuned, so that the pressure acting on the patient's puncture site can be fine-tuned to reduce, thereby making the patient more comfortable.

[0091] It should be noted that the design of the ratchet 22 and the pawl 24 ensures that the second rolling rod 82 can maintain a stable position when not actively driven to prevent accidental rotation; the user can easily control the winding and releasing of the pressure belt 4 by rotating the adjustment shaft 20, and the operation is simple and quick; the second adjustment mechanism is designed inside the lower pressure block 2, with a compact and beautiful structure; the safety and stability of the adjustment process are ensured by the combination of mechanical locking mechanism and hydraulic transmission.

[0092] Furthermore, it also includes two side pressure blocks 3 of the same structure. The pressure measuring blocks 3 are sleeved on the pressure belts 4 at both ends of the upper pressure block 1. The pressure measuring blocks 3 are slidably connected to the pressure belts 4 and can slide on the pressure belts 4.

[0093] It should be understood that, based on the above-mentioned feature definition, the side pressure blocks 3 are sleeved on the pressure belts 4 at both ends of the upper pressure block 1 and are kept in sliding connection with the pressure belts 4; this design ensures that the side pressure blocks 3 can slide on the pressure belts 4 to change their positions; at the same time, the presence of the side pressure blocks 3 helps to distribute the squeezing force more evenly; this can not only improve the hemostatic effect, but also reduce the damage to the surrounding tissues caused by uneven pressure distribution; because the side pressure blocks 3 and the pressure belts 4 are slidably connected, they can adapt to wounds of different sizes and shapes to a certain extent; this design improves the flexibility and applicability of the hemostatic device.

[0094] Furthermore, two side pressure blocks of the same structure form a cross structure with the upper pressure block and the lower pressure block, which distributes the extrusion force more evenly. The side pressure blocks help to improve the hemostasis efficiency, reduce the amount of bleeding and the time of hemostasis; the uniform pressure distribution can reduce damage to surrounding tissues and reduce the risk of complications; the slidingly connected side pressure blocks enable the hemostatic device to adapt to wounds of different sizes and shapes, improving its applicability and flexibility; the side pressure blocks that are easy to install and adjust make the use of the hemostatic device more convenient and comfortable, and enhance the user experience.

[0095] Further, the side pressure block 3 includes:

[0096] The side pressure block body is provided with a curved groove inside, and openings are provided at both ends of the pressure measuring block body, and the curved groove and the opening are connected;

[0097] The rotating rod 301 is rotatably disposed in the curved groove; the pressing belt 4 contacts the rotating rod 301 .

[0098] It should be understood that, based on the above-mentioned feature definitions, the side pressure block can slide on the pressure belt through its internal curved groove and openings at both ends; the rotating design of the rotating rod helps to reduce the friction of the pressure belt when it slides inside the side pressure block; this can not only reduce the wear rate of the pressure belt, but also improve the overall service life of the hemostatic device; the rotation of the rotating rod can also help disperse the pressure on the pressure belt; because the design of the side pressure block allows the pressure belt to slide freely inside it and be supported and guided by the rotating rod, this structure can adapt to wounds of different sizes and shapes, thereby improving the applicability and flexibility of the hemostatic device.

[0099] Furthermore, soft rubber pads are arranged inside the upper pressing block 1 , the lower pressing block 2 and the pressure measuring block 3 .

[0100] It should be understood that, based on the above-mentioned feature definitions, the soft rubber pad helps to improve the overall effect of the hemostatic device by protecting the wound, increasing sealing and improving comfort; because the soft rubber pad can reduce pressure damage to the skin and tissue, it helps to reduce the risk of complications caused by compression; the comfortable touch and anti-slip properties make the hemostatic device more stable and reliable during use, improving the patient's experience.

[0101] According to a nursing hemostatic device of the present embodiment, after the patient has undergone radial artery puncture, the nurse passes the patient's entire arm through the annular hemostatic device so that the arm is placed on the soft rubber pad on the top of the lower pressure block 2, and then adjusts the side pressure blocks 3 on both sides so that they can fit the bends on both sides of the arm, and then rotates the swivel 9. When the swivel 9 rotates, it drives the gear ring 901 to rotate synchronously, and the gear ring 901 drives the gear ring 11 to rotate synchronously, and the gear ring 11 drives the rotating shaft 10 to rotate synchronously. When the rotating shaft 10 rotates, the winding strip 14 pulls the moving block 12 to slide into the adjusting groove 102, and the air in the adjusting groove 102 is discharged to the outside through the air outlet 106, and the moving block 1 2 moves, driving the moving plate 13 to move synchronously, thereby driving the first rolling rod 81 to move toward the inside of the first winding groove 101, so that the driven gear 16 at the end of the first rolling rod 81 meshes and rotates with the tooth groove 105. The first rolling rod 81 moves to store the pressure belt 4 into the first winding groove 101, and rotates to wind the pressure belt 4 around its outer ring, so that the hemostatic device is gradually tightened until the pressure of the hemostatic pad 6 on the puncture point reaches the required pressure, and then the rotation of the rotating ring 9 is stopped. After that, the ratchet 22 can be driven to rotate by rotating the adjusting shaft 20, thereby driving the second rolling rod 82 in the second winding groove 201 to rewind the pressure belt 4 to a certain extent, so as to achieve further fine-tuning of the pressure;

[0102] At this time, since the air pressure in the adjustment groove 102 will affect the overall pressure of the hemostatic device after the swivel 9 is adjusted, the slider 21 can be driven to move outward by rotating the screw rod 19 outward, so that the arc block 23 slides downward according to the hydraulic pressure transmission in the hydraulic chamber 202 and the connecting hole 205, thereby driving the pawl 24 to limit the rotation of the ratchet wheel 22, so that the second rolling rod 82 in the lower pressure block 2 is used to fine-tune the pressure to ensure the hemostatic pressure;

[0103] After a period of compression and hemostasis, it is only necessary to slightly rotate the screw rod 19 inwards to drive the slider 21 to move inwards. At this time, the hydraulic pressure in the hydraulic chamber 202 flows into the arc-shaped slide groove 204 through the connecting hole 205, thereby driving the arc block 23 to slide upward, and the limit of the ratchet 24 moves upward. At this time, the pressure is released to a certain extent, and the pressure belt 4 will be loosened from the second winding rod 82 by a small length to relieve a certain amount of pressure, thereby avoiding long-term high pressure on the puncture point. The pressure can be adjusted multiple times in the future by this method, or by quickly pressing the pressure relief valve rod 18 on the upper pressure block 1 multiple times to allow air to enter the adjustment groove 102, thereby adjusting the displacement of the moving block 12 to make the winding rod 8 move toward the opening end of the first winding groove 101 to achieve the release of the pressure belt 4, which can also play the effect of adjusting the pressure, but this adjustment is a coarse adjustment;

[0104] When the hemostasis time is up, press the pressure relief valve rod 18 so that the moving block 12 is reset under the action of the spring 15. At this time, the winding rod 8 in the first winding groove 101 also returns to the initial position, and the pressing belt 4 is released. At this time, the entire hemostasis device is loosened and can be removed from the arm. Subsequently, the mounting block 5 and the hemostatic pad 6 can be replaced by loosening the stud 7 to suit different people and puncture conditions.
