Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and more specifically, to a single-hand adjustable knob-type pressure hemostasis device. Background Technology
[0002] Earthquakes, typhoons, natural disasters, car accidents, military training, or battlefield injuries can all cause severe bleeding in the injured areas. If the bleeding is not controlled quickly, it can lead to hemorrhagic shock, resulting in the loss of the opportunity for treatment and seriously threatening the injured person's life. If the bleeding can be stopped quickly, accurately, and effectively, it can buy time for further treatment and save the injured person's life.
[0003] Currently, in domestic civilian and battlefield first aid, the commonly used hemostatic device is a wrench-type pressure device. Rotating the wrench tightens the elastic bands at both ends, thereby further pressurizing the bleeding site to achieve hemostasis. The degree of pressure is determined by the number of rotations of the wrench. It is relatively cumbersome to operate. Generally, the wrench is relatively long to facilitate tightening of the elastic bands. However, if the wrench is too long, it is easy to poke the wound or the injured person's body during use. Furthermore, after the pressure is applied, additional fixing parts are needed to secure the wrench to maintain the pressure effect, increasing the number of steps required for hemostasis, making it cumbersome and inefficient.
[0004] To solve the above-mentioned technical problems, a knob-type pressure hemostasis device with application number CN 115804627 A is proposed. When pressure needs to be applied to the bleeding site, pressing the pressing lever will allow the locking lever to continue to lock the ratchet disc in a clockwise direction. Through the above working principle, it is convenient to use when stopping bleeding at the patient's wound, and it is also convenient and quick to adjust the pressure applied to the bleeding site, thereby improving the hemostasis efficiency.
[0005] However, when releasing the ratchet disc, the pressing rod needs to be pressed down to make the locking rod slide from the groove at the top of the locking groove along the arc at the side end to the groove at the bottom of the locking groove. However, when unlocking the locking rod, the pressing rod is also pressed down. When the locking rod enters the corner at the top of the arc at the side end, the pressing rod needs to be released and the locking rod moved towards the groove. However, the locking rod may not necessarily move towards the groove along the trajectory. It may return along the original path of the arc and fail to lock. Multiple operations are required, which is troublesome and delays the best time for hemostasis. Summary of the Invention

[0014] Optionally, the two wire ropes are wound together into a single strand, and the two wire ropes are wound inside the take-up groove.
[0015] Optionally, a compression assembly is provided on one side of the mounting box. The compression assembly includes a storage slot formed on the mounting box. A compression plate is slidably connected inside the storage slot. A C-shaped plate is fixedly connected to the front side of the compression plate. A threaded rod is rotatably connected to the front side of the C-shaped plate.
[0016] Optionally, the front side of the threaded rod extends out of the interior of the mounting box, the bottom of the front side of the mounting box is provided with a threaded hole, the threaded rod is threadedly connected to the threaded hole, the front side of the extrusion plate is provided with a connecting rod, the front side of the connecting rod extends into the interior of the mounting box, and the C-shaped plate is located inside the mounting box.
[0017] Optionally, the top and bottom of the mounting box are provided with fixing components. The fixing components include a mounting frame fixed on the mounting box. Two pins are inserted into both sides of the mounting frame. The outer surfaces of the two pins are fitted with mounting shafts.

[0018] Optionally, a connecting seat is fixedly connected to one side of the inner surface of the mounting frame, a rotating shaft is rotatably connected inside the connecting seat, a stop bar is fixedly connected to the middle of the outer surface of the rotating shaft, and a coil spring is fixedly connected to the outer surface of the rotating shaft.
[0019] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:
[0020] In the above solution, a pressure-applying component is installed. By rotating the handle counterclockwise, the winding groove winds up and wraps the two ropes, gradually tightening the first and second bandages to apply pressure to the wound for hemostasis. Pulling the lever moves the ratchet away from under the locking lever via the connecting rod. At this point, the handle can be rotated clockwise to release the wire rope from the inside of the winding groove. This avoids prolonged high-intensity pressure hemostasis, which can cause pain, numbness, and other discomfort to the patient. Releasing the ratchet from its fixed state is more convenient, saving time. One-handed operation is also more convenient, reducing inconvenience for the patient and saving time.
[0021] By incorporating connecting components, multiple connecting lines and connecting sleeves can effectively distribute the tension of the steel wire rope, preventing excessive local tension from causing the connecting sleeves and connecting cloth to break. This also prevents the tourniquet from being unable to continue applying pressure for hemostasis, effectively increasing the service life of the hemostasis device, reducing the waste of medical resources, and saving costs.
[0022] By incorporating a fixing component, when stopping bleeding at a patient's wound, after covering the wound with the mounting box, the first bandage, and the second bandage, the adhesive tape is pulled out from inside the mounting frame. Once fully pulled out, the tape is adhered to the patient's skin. Similarly, the lower adhesive tape is pulled out and adhered to the patient's skin, providing initial fixation for the mounting box, the first bandage, and the second bandage. This prevents the first and second bandages from detaching from the wound during bandaging and allows for quick connection of the first and second bandages, improving bandaging efficiency and reducing patient pain.

[0047] like Figures 1 to 9 As shown in the figure, an embodiment of the present invention provides a single-hand adjustable knob-type pressure hemostasis device, including a first bandage 1 and a second bandage 2. A first Velcro 3 is fixedly connected to one side of the first bandage 1, an opening 4 is provided at one end of the inside of the second bandage 2, a second Velcro 5 is fixedly connected to one side of the second bandage 2, and a pressure component 6 is provided between the first bandage 1 and the second bandage 2.
[0048] like Figures 2 to 4 As shown, the pressure assembly 6 includes a mounting box 61 fixed between the second bandage 2 and the first bandage 1, and a connecting assembly 67 disposed on the front side of the first bandage 1 and the second bandage 2. A fixing plate 62 is fixedly connected to one side of the inner surface of the mounting box 61. A locking rod 63 is rotatably connected to the front side of the fixing plate 62. A spring 68 is fixedly connected to the back side of the locking rod 63 and the back side of the fixing plate 62, with the direction facing the mounting box 61 as the back side direction. A rotating handle 65 is rotatably connected to one side of the inner surface of the mounting box 61. A winding groove 69 is opened at one end of the outer surface of the rotating handle 65. An unlocking assembly 66 is disposed inside the rotating handle 65. A ratchet disc 64 is disposed on the rotating handle 65.
[0049] A sponge pad is provided on one side of the back of the mounting box 61. A connecting post is fixedly provided on one end of the back of the locking rod 63 and one end of the back of the fixing plate 62. The two ends of the spring 68 are sleeved on the two connecting posts. The locking rod 63 and the teeth on the ratchet disc 64 are matched and engaged with each other. A stop is provided at the front edge of the fixing plate 62, and the stop supports the locking rod 63.
[0050] like Figure 5 As shown, the unlocking component 66 includes a pull rod 661 that slides inside the handle 65, two slots 665 that are symmetrically opened on the outer surface of the handle 65, and a first magnet 662 that is fixed to one end of the inner surface of the handle 65. A connecting rod 664 is symmetrically fixed to the outer surface of the pull rod 661. The connecting rod 664 passes through the slots 665 and is slidably connected inside the slots 665. A second magnet 663 is fixedly connected to one end inside the slots 665.
[0051] The connecting rod 664 slides inside the slot 665. One side of the connecting rod 664 is fixedly connected to one side of the ratchet disk 64. The pull rod 661 and the first magnet 662 attract each other. The ratchet disk 64 is sleeved on the outer surface of the handle 65. The handle 65 and the ratchet disk 64 slide and adapt to each other.
[0052] like Figure 1 and Figure 6 As shown, the connecting assembly 67 includes a connecting cloth 671 fixed to the front side of the first bandage 1 and the second bandage 2. Multiple connecting sleeves 672 are evenly fixedly connected to the front side of the connecting cloth 671. Connecting wires 673 are inserted inside the connecting sleeves 672. Steel wire ropes 674 are fixedly connected to the top and bottom of the multiple connecting wires 673. The outer surface of the connecting sleeves 672 is covered with a covering cloth 675.
[0053] The two wire ropes 674 at the top and bottom are intertwined into one strand, and the two wire ropes 674 are wound inside the winding groove 69.
[0054] When bandaging and stopping the bleeding of the patient, the mounting box 61, the first bandage 1, and the second bandage 2 are placed over the wound. One end of the first bandage 1 is passed through the opening 4 and tightened. Then, the first Velcro 3 and the second Velcro 5 are pressed and glued together to complete the initial fixation and pressure. The positions of the first bandage 1 and the second bandage 2 are adjusted so that they coincide with the wound. The handle 65 is rotated counterclockwise, which drives the connecting rod 664 and the ratchet disc 64 to rotate synchronously through the slot 665. The locking rod 63 slides relative to the surface of the handle 65. When the handle 65 rotates, the two steel wire ropes 674 on the same side are wound into one rope. The winding groove 69 winds and winds the two ropes. The steel wire ropes 674 pull multiple connecting lines 673 toward the middle (the position of the mounting box 61 is the middle). The connecting lines 673, through the cooperation of the connecting sleeve 672 and the connecting cloth 671, drive one end of the first bandage 1 and the second bandage 2. One end of bandage 2 moves closer to the center, causing the first bandage 1 and the second bandage 2 to gradually tighten, applying pressure to the wound to stop bleeding. Multiple connecting lines 673 and connecting sleeves 672 are provided to effectively distribute the tension of the wire rope 674, preventing excessive local tension from causing the connecting sleeves 672 and connecting cloth 671 to break, thus preventing the tourniquet from continuing to apply pressure to stop bleeding. When the first bandage 1 and the second bandage 2 are pressed to a suitable pressure, the rotation of the handle 65 can be stopped. At this time, the locking rod 63 is pulled by the spring 68. Because the locking rod 63 is pulled by the spring 68, the locking rod 63 is tightly attached to the surface of the ratchet disc 64. When the ratchet disc 64 rotates clockwise, the teeth of the ratchet disc 64 will abut against the locking rod 63, so the ratchet disc 64 cannot rotate clockwise, locking the handle 65 and preventing it from rotating clockwise, thus completing the pressure to stop bleeding.
[0055] The end of the pull rod 661 protrudes outside the handle 65. When it is necessary to release the pressure hemostasis state, pulling the end of the pull rod 661 drives the connecting rod 664 to slide inside the slot 665. The connecting rod 664 drives the ratchet disc 64 to slide on the outer surface of the handle 65. The second magnet 663 attracts and fixes the connecting rod 664, so that the ratchet disc 64 moves away from under the locking rod 63. At this time, the handle 65 can be rotated clockwise to loosen the wire rope 674 from inside the winding slot 69, avoiding prolonged high-intensity pressure hemostasis, which may cause pain, numbness and other discomfort to the patient. Releasing the fixed state of the ratchet disc 64 is more convenient and saves time. It can be operated with one hand, reducing the trouble for the patient.
[0056] like Figures 8 to 9 As shown, a compression assembly 8 is provided on one side of the mounting box 61. The compression assembly 8 includes a storage groove 84 opened on one side of the back of the mounting box 61. A compression plate 83 is slidably connected inside the storage groove 84. An upward-facing C-shaped plate 82 is fixedly connected to the front side of the compression plate 83. A threaded rod 81 is rotatably connected to the front side of the C-shaped plate 82.
[0057] The front side of the threaded rod 81 extends out of the interior of the mounting box 61. A threaded hole is provided at the bottom of the front side of the mounting box 61. The threaded rod 81 is threadedly connected to the threaded hole. A connecting rod is provided on the front side of the extrusion plate 83. The front side of the connecting rod extends into the interior of the mounting box 61. The shaped plate 82 is located inside the mounting box 61.
[0058] After a period of pressure-based hemostasis, prolonged or improper pressure on the covered area may lead to complications such as skin damage, pressure sores, subcutaneous bleeding, or local hematoma. Once the wound stops bleeding, the hemostatic device can be loosened appropriately to reduce pressure. The ratchet disc 64 and locking lever 63 are then separated. The handle 65 is rotated clockwise to unwind the wire rope 674 to a certain length. The locking lever 63 then secures the reset ratchet disc 64. The threaded rod 81 is then rotated, and the threaded action causes the compression plate 83 to move out of the storage slot 84 via the U-shaped plate 82. This allows the compression plate 83 to contact the patient's skin, creating a gap between the mounting box 61, the first bandage 1, the second bandage 2, and the skin. This allows for ventilation and drying of the skin at the compression site, ensuring comfort and reducing the risk of pressure sores, subcutaneous bleeding, or local hematoma. The back of the sponge pad has an adhesive layer, and the sponge pad has an opening that matches the compression plate 83, allowing for easy replacement after use.
[0059] like Figures 1 to 7 As shown, the mounting box 61 is provided with fixing components 7 at both the top and bottom. The fixing components 7 include a mounting frame 71 fixed to the top of the mounting box 61. Pins 75 are inserted into both sides of the mounting frame 71. Mounting shafts 76 are sleeved on the outer surfaces of the two pins 75. Adhesive tape 77 is provided on the outer surface of the mounting shafts 76.
[0060] A connecting seat 72 is fixedly connected to one side of the inner surface of the mounting frame 71. A rotating shaft 78 is rotatably connected inside the connecting seat 72. A stop bar 73 is fixedly connected to the middle of the outer surface of the rotating shaft 78. A coil spring 74 is fixedly connected to the outer surface of the rotating shaft 78.
[0061] When stopping bleeding at a patient's wound, during the process of connecting the first bandage 1 and the second bandage 2 while covering the wound with the hemostatic device, the first bandage 1 and the second bandage 2 may be in a loose state, causing them to slip off the wound. This not only increases the patient's pain but also requires adjustment time and reduces the efficiency of hemostasis. Therefore, after covering the wound with the mounting box 61, the first bandage 1, and the second bandage 2, the adhesive tape 77 is pulled out from inside the mounting frame 71. After being fully pulled out, the adhesive tape 77 is... Adhesive tape 77 is applied to the patient's skin. Similarly, the adhesive tape 77 below is pulled out and adhered to the patient's skin to initially fix the mounting box 61, the first bandage 1, and the second bandage 2. When binding, prevent the first bandage 1 and the second bandage 2 from coming off the wound. The first bandage 1 and the second bandage 2 can be quickly connected to improve the efficiency of bandaging and reduce the patient's pain. When changing the adhesive tape 77, the two pins 75 can be pulled out, and the mounting shaft 76 and the used adhesive tape 77 can be removed simultaneously. The new adhesive tape 77 can then be reinstalled.
[0062] The workflow of the technical solution provided by this invention is as follows:
[0063] When stopping the bleeding at the patient's wound, after covering the wound with the mounting box 61, the first bandage 1 and the second bandage 2, pull the adhesive tape 77 out from the inside of the mounting frame 71. After pulling it out completely, stick the adhesive tape 77 to the patient's skin. Similarly, pull out the lower adhesive tape 77 and stick it to the patient's skin to initially fix the mounting box 61, the first bandage 1 and the second bandage 2. When binding, prevent the first bandage 1 and the second bandage 2 from coming off the wound. Pass one end of the first bandage 1 through the opening 4 and pull it tight. Then squeeze and stick the first Velcro 3 and the second Velcro 5 together to complete the initial fixation and pressure.
[0064] Rotating the handle 65 counterclockwise causes the connecting rod 664 and ratchet disc 64 to rotate synchronously through the slot 665. The locking rod 63 slides relative to the surface of the handle 65. When the handle 65 rotates, the two steel wire ropes 674 on the same side are wound into one rope. The winding groove 69 winds up the two ropes. The steel wire ropes 674 pull multiple connecting lines 673 closer to the center. The connecting lines 673, through the cooperation of the connecting sleeve 672 and the connecting cloth 671, drive one end of the first bandage 1 and one end of the second bandage 2 closer to the center, so that the first bandage 1 and the second bandage 2 gradually tighten, thus protecting the wound. Pressure hemostasis is applied at the incision site. Multiple connecting lines 673 and connecting sleeves 672 are provided to effectively distribute the tension of the wire rope 674, preventing excessive local tension from causing the connecting sleeves 672 and connecting cloth 671 to break. This also prevents the tourniquet from being unable to continue applying pressure hemostasis. When the first bandage 1 and the second bandage 2 are pressurized to an appropriate level, the rotation of the handle 65 can be stopped. At this time, the locking rod 63 is pulled by the spring 68, and the locking rod 63 is tightly attached to the surface of the ratchet disc 64, preventing the handle 65 from rotating clockwise, thus completing the pressure hemostasis.
[0065] After a period of pressure hemostasis, the hemostatic device can be loosened appropriately to reduce the pressure. The ratchet disc 64 and locking rod 63 are pulled apart, and the handle 65 is rotated clockwise to unwind the wire rope 674 to a certain length. The ratchet disc 64 is then fixed in place by the locking rod 63. At this time, the threaded rod 81 is rotated, and under the action of the thread, the compression plate 83 is moved out of the storage groove 84 through the U-shaped plate 82, so that the compression plate 83 comes into contact with the patient's skin. This creates a gap between the installation box 61, the first bandage 1, and the second bandage 2 and the skin, allowing the skin at the compression site to be ventilated and dried, ensuring the comfort of the skin at the compression site.
