Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an integrated limb fixation device for restraint and hemostasis. Background Art

[0002] In scenarios such as clinical emergency care, psychiatric care, emergency treatment, and patient transport, pressure hemostasis and limb restraint are two crucial intervention measures. Pressure hemostasis refers to the application of continuous and steady pressure to the wound to physically compress blood vessels, slowing or preventing blood outflow. It is a key means of controlling severe bleeding (especially arterial bleeding) and is often used in trauma treatment. Limb restraint refers to the use of physical devices (such as restraints and fixation devices) to limit the patient's range of motion. It is mainly used to prevent patients with impaired consciousness, mental abnormalities, or extreme agitation from harming themselves or others, removing important lines (such as intravenous infusion lines and drainage tubes), or interfering with necessary medical procedures, in order to ensure the safety of the patient and those around them.

[0003] However, existing technical solutions have significant drawbacks: traditional pressure-assisted hemostasis devices (such as bandages, gauze rolls, and tourniquets) and limb restraint devices (such as conventional restraint belts and fixation plates) are typically designed and used independently. When faced with patients requiring both effective hemostasis and reliable restraint (such as agitated patients with severe traumatic bleeding), the two devices struggle to work together and may even interfere with each other. The application of restraint belts may obscure or hinder precise pressure application to the wound, while effective pressure bandages often struggle to achieve adequate restraint because the restraint belts cannot securely adhere or the pressure points are obscured by the restraint structure. Medical staff are forced to choose between the two or frequently switch between them, which not only delays the optimal treatment opportunity and increases operational complexity, but also potentially leads to poor hemostasis or restraint failure, endangering patient safety. Summary of the Invention

[0004] The present application aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, one purpose of this application is to provide a limb fixation device that combines restraint and hemostasis.

[0006] To achieve the above-mentioned objectives, the first embodiment of the present application proposes an integrated limb fixation device for restraint and pressurized hemostasis, comprising a base assembly, a placement belt, a restraint mechanism, two telescopic mechanisms, an airbag mechanism, an extension belt, a clamping belt, a clamping mechanism, a rectangular frame and a mounting plate, wherein the base assembly comprises a bottom plate, two extension plates and a hook-surface Velcro, wherein the two extension plates are arranged on both sides of one end of the bottom plate, and the hook-surface Velcro is arranged on the side of the bottom plate; the placement belt is on the bottom plate, the airbag mechanism is arranged on one side of the placement belt, and the clamping belt is arranged on the other side of the placement belt opposite to the airbag mechanism; the extension belt is provided with a fleece-surface Velcro, and the extension belt and the clamping belt are connected; a strip opening is opened on the clamping belt, and the two telescopic mechanisms are respectively arranged on both sides of the clamping belt; the two ends of the clamping mechanism are respectively arranged on the two extension plates; the mounting plate is arranged on the clamping mechanism; the rectangular frame is arranged at the top of the clamping mechanism, and the restraint mechanism is arranged at the bottom of the clamping mechanism; the positions of the restraint mechanism and the placement belt are relative.

[0007] The integrated limb fixation device for restraint and pressurized hemostasis of the embodiment of the present application can realize the coordinated operation of pressurized hemostasis and limb restraint, avoiding mutual interference when traditional devices are used independently. When facing patients who are agitated and accompanied by severe traumatic bleeding, the wound can be accurately pressurized to stop bleeding, and the limb can be firmly restrained at the same time, without the need for medical staff to frequently switch between the two operations. It greatly saves treatment time, improves the success rate of hemostasis, reduces the difficulty and intensity of medical staff's work, and reduces errors caused by complex operations. At the same time, sufficient restraint can prevent patients from aggravating injuries due to agitation, ensure the safety and order of the treatment process, and comprehensively improve the treatment effect and safety of patients.

[0008] In addition, the above-mentioned integrated limb fixation device for restraint and hemostasis proposed in this application may also have the following additional technical features:

[0009] In one embodiment of the present application, the airbag mechanism includes a pressing belt, an airbag assembly, two threaded columns, two rotating seats, a positioning plate, two torsion bars, two moving blocks, two second magnetic blocks and a pressing frame, wherein the pressing belt is connected to one end of the placement belt, and grooves are respectively provided on both sides of the pressing belt; the positioning plate is arranged inside the pressing belt; one end of the airbag assembly is connected to the middle part of the positioning plate, and the two rotating seats are respectively arranged on both sides of the positioning plate; one end of the threaded column is connected to the rotating seat, and the torsion bar is arranged at the other end of the threaded column; the pressing frame is sleeved on the airbag assembly, and the two moving blocks are respectively arranged on both sides of the two pressing frames, and the moving blocks are threadedly connected to the corresponding threaded columns; the second magnetic block is arranged on the moving block.

[0010] In one embodiment of the present application, the airbag assembly includes a plurality of airbag bodies and a plurality of connecting airbags, wherein the connecting airbag is arranged between two adjacent airbag bodies; and the airbag bodies and the connecting airbags are internally communicated.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] The airbag mechanism adjusts the compression position. Turning the torsion bar drives the threaded post on the rotating seat. This rotation of the threaded post moves the movable block, which in turn moves the pressure frame, applying pressure to the airbag assembly. The multiple airbag bodies in the airbag assembly are connected by connecting airbags, which can evenly transmit pressure to the wound, achieving precise pressure to stop bleeding.

[0039] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0040] The following describes the integrated restraint and hemostasis device for limbs according to an embodiment of the present application with reference to the accompanying drawings.

[0041] The integrated limb immobilization device for restraint and hemostasis provided in the embodiments of this application can be used for patients with agitation and severe traumatic bleeding, as well as for routine hemostasis in ordinary patients. It can achieve the coordinated operation of hemostasis and limb restraint, effectively avoiding the mutual interference caused by the independent use of traditional devices.

[0042] like Figures 1-8 As shown, the integrated limb fixation device for restraint and pressurized hemostasis of an embodiment of the present application may include a base assembly 1, a placement belt 2, a restraint mechanism 3, two telescopic mechanisms 4, an airbag mechanism 5, an extension belt 6, a snap-on belt 7, a clamping mechanism 8, a rectangular frame 9 and a mounting plate 10.

[0043] The base assembly 1 may include a bottom plate 11 , two extension plates 12 and a hook-surface Velcro 13 , wherein the two extension plates 12 are arranged on both sides of one end of the bottom plate 11 , and the hook-surface Velcro 13 is arranged on the side of the bottom plate 11 .

[0044] It should be noted that the shapes of the two extension plates 12 and the bottom of the clamping mechanism 8 correspond to each other, and can achieve stable support for the clamping mechanism 8 .

[0045] The support belt 2 is located on the base plate 11 .

[0046] It should be noted that a blood oxygen detector may be provided at the bottom of the placement belt 2 for detecting the patient's hemostasis condition.

[0047] Optionally, a detachable device, such as a buckle, snap button, or Velcro, may be provided between the placement belt 2 and the base plate 11, so as to enable the placement belt 2 to be separated from the base assembly 1. The specific structures of the snap button and Velcro are common knowledge in the art and will not be described in detail here.

[0048] Furthermore, when Velcro is used to connect the placement strap 2 and the base assembly 1, a Velcro surface can be provided on the placement strap 2 to adhere to the surface of the extension strap 6. Specifically, when performing hemostasis on a normal patient, after adjusting the airbag position, the pressure strap 51 is passed through the strip opening 71, and the extension strap 6 is wrapped around the surface of the airbag mechanism 5 and adhered to the bottom of the placement strap 2. This allows the device to be disassembled for use as a standard tourniquet, and facilitates subsequent removal and cleaning of the placement strap 2.

[0049] The airbag mechanism 5 is arranged on one side of the placement belt 2, and the clip belt 7 is arranged on the other side of the placement belt 2 opposite to the airbag mechanism 5. The extension belt 6 is provided with a fleece-surfaced Velcro 61, and the extension belt 6 and the clip belt 7 are connected.

[0050] It should be noted that the airbag mechanism 5 can adjust the pressurized position of the airbag according to the injured position, so that the pressurized hemostasis point is more accurate.

[0051] A strip-shaped opening 71 is provided on the clamping belt 7 , and two telescopic mechanisms 4 are respectively arranged on both sides of the clamping belt 7 .

[0052] It should be noted that the width of the strip opening 71 is not less than the width of the airbag mechanism 5 , thereby ensuring that the end of the airbag mechanism 5 passes through the strip opening 71 .

[0053] Both ends of the clamping mechanism 8 are respectively arranged on two extension plates 12 , the mounting plate 10 is arranged on the clamping mechanism 8 , the rectangular frame 9 is arranged on the top of the clamping mechanism 8 , and the restraint mechanism 3 is arranged on the bottom of the clamping mechanism 8 .

[0054] The width of the rectangular frame 9 is not less than the width of the extension belt 6 , so that the extension belt 6 can pass through the rectangular frame 9 easily.

[0055] Specifically, when the mounting plate 10 moves downward, the clamping mechanism 8 can clamp the uninjured area of ​​the patient's limb, thereby restraining the patient's limb.

[0056] The restraining mechanism 3 is located opposite to the placement belt 2 .

[0057] refer to Figure 2 In one embodiment of the present application, the airbag mechanism 5 may include a pressing belt 51, an airbag assembly 52, two threaded columns 53, two rotating seats 54, a positioning plate 55, two torsion bars 56, two moving blocks 57, two second magnetic blocks 58 and a pressing frame 59.

[0058] The pressing belt 51 is connected to one end of the placement belt 2, and grooves 511 are respectively provided on both sides of the pressing belt 51, and the positioning plate 55 is provided inside the pressing belt 51. It can be understood that the grooves 511 are provided to facilitate the movement of the pressing frame 59.

[0059] One end of the airbag assembly 52 is connected to the middle of the positioning plate 55 , two rotating seats 54 are respectively arranged on both sides of the positioning plate 55 , one end of the threaded column 53 is connected to the rotating seat 54 , and the torsion bar 56 is arranged at the other end of the threaded column 53 .

[0060] It should be noted that the material of the threaded column 53 can be spring steel or thermoplastic elastomer, such as TPE or TPU. In this way, it can be ensured that the threaded column 53 can return to its original state after bending without affecting the movement of the pressing frame 59.

[0061] Further, refer to Figure 3 In one embodiment of the present application, the airbag assembly 52 may include a plurality of airbag bodies 521 and a plurality of connecting airbags 522 .

[0062] The connecting airbag 522 is disposed between two adjacent airbag bodies 521 , and the interiors of the airbag bodies 521 and the connecting airbag 522 are in communication with each other, so that the gas between the airbag bodies 521 can be transferred to each other through the connecting airbag 522 .

[0063] The pressing frame 59 is sleeved on the airbag assembly 52 , and the two moving blocks 57 are respectively arranged on both sides of the two pressing frames 59 . The moving blocks 57 are threadedly connected to the corresponding threaded columns 53 .

[0064] Specifically, rotating the torsion bar 56 drives the threaded post 53 to rotate on the rotating seat 54. The rotation of the threaded post 53 causes the moving block 57 to move, which in turn drives the pressing frame 59 to move, applying pressure to the airbag assembly 52. ​​The multiple airbag bodies 521 in the airbag assembly 52 are connected by connecting airbags 522, which can collect the gas in the airbag bodies 521 to correspond to the location of the wound.

[0065] The second magnetic block 58 is provided on the moving block 57. It should be noted that the telescopic mechanism 4 can be magnetically attracted to the second magnetic block 58, thereby positioning the pressing frame 59 and further positioning the pressurized position of the airbag assembly 52.

[0066] refer to Figure 8 Optionally, in one embodiment of the present invention, two matching grooves 111 are opened on the other side bottom plate 11 opposite to the position of the hook surface Velcro 13, and the position between the two matching grooves 111 corresponds to the position of the two torsion bars 56.

[0067] Specifically, when the convergence position in the airbag body 521 is adjusted, the threaded column 53 is bent, and the torsion bars 56 on both sides are passed through the strip opening 71, and then the torsion bars 56 are placed in the matching grooves 111. This not only limits the movement of the moving block 57, but also limits the compression position of the airbag body 521.

[0068] Optionally, a patterned groove that matches the surface of the torsion bar 56 may be provided inside the matching groove 111 to prevent the torsion bar 56 from moving out of the matching groove 111 .

[0069] refer to Figure 4 and Figure 5 In one embodiment of the present application, the clamping mechanism 8 may include a shell 81, two wedge blocks 82, two limiting arc blocks 83, two support rods 84, two second springs 85, a connecting plate 86 and two cylinders 87.

[0070] Among them, the shell 81 is composed of two "L" shapes, two support rods 84 are arranged inside the shell 81, the connecting plate 86 is arranged on the support rod 84, and the cylinder 87 is arranged at the bottom of the support rod 84; one end of the second spring 85 is connected to the bottom of the support rod 84, and the other end of the second spring 85 is connected to the inner wall of the shell 81; the wedge block 82 is arranged on one side of the support rod 84, and an inclined groove 821 is opened on the wedge block 82, the limiting arc block 83 is arranged on the wedge block 82, the wedge block 82 and the shell 81 are slidably connected, and the cylinder 87 is arranged inside the inclined groove 821.

[0071] Specifically, when the connecting plate 86 moves downward, it drives the support rod 84 downward. During this downward movement of the support rod 84, the cylinder 87 on the support rod 84 moves downward. However, because the cylinder 87 is restricted by the inclined groove 821 within the wedge block 82, the cylinder 87 moves within the inclined groove 821, moving from a high position within the inclined groove 821 to a low position within the inclined groove 821. During this process, the wedge block 82 moves out of the housing 81, driving the two limiting arc blocks 83 closer together, thereby restricting and clamping the limb.

[0072] It should be noted that clinical work requires that there should be a limit to the restraint of the patient. When adjusting the distance between the two limiting arc blocks 83, the distance between the two limiting arc blocks 83 can be adjusted according to the transverse diameter of the patient's limb to ensure that the appropriate restraint range is achieved.

[0073] It is understandable that when the support rod 84 moves downward, it will press the second spring 85. When the pressure on the connecting plate 86 is released, the support rod 84 will rebound upward due to the elastic force of the second spring 85 and return to its initial state.

[0074] refer to Figure 6 In one embodiment of the present application, the constraint mechanism 3 may include a limiting arc 31 , a pressure block 32 and two first springs 33 .

[0075] Among them, the limiting arc 31 is set at the bottom of the mounting plate 10, and slots 311 are opened on both sides of the inner wall of the limiting arc 31. The two ends of the pressure block 32 are respectively set inside the slot 311, one end of the first spring 33 is connected to the top of the slot 311, and the other end of the first spring 33 is connected to the top of the pressure block 32.

[0076] When the mounting plate 10 moves downward, the pressing block 32 and the airbag assembly 52 approach each other, and the arcs on both sides of the limiting arc 31 can gather the gas in the airbag body 521 to the bottom of the pressing block 32. At this time, the airbag body 521 can be pressurized by the pressing block 32, and the first springs 33 on both sides synchronously press the two sides of the pressing block 32 to enhance the pressurization effect.

[0077] refer to Figure 7 In one embodiment of the present application, the telescopic mechanism 4 may include a fixed block 41 , a telescopic belt 42 , a first magnetic block 43 , a clockwork spring 44 and a rotating shaft 45 .

[0078] Among them, the fixed block 41 is set on the clamping belt 7, the rotating shaft 45 is rotatably set inside the clamping belt 7, the inner ring of the clockwork spring 44 is fixedly connected to the surface of the rotating shaft 45, and the outer ring can be rotated through the rotating shaft. One end of the telescopic belt 42 is connected to the outer ring of the clockwork spring 44.

[0079] It is understandable that the combination of the clockwork spring 44 and the telescopic belt 42 can provide the telescopic belt 42 with a strong pulling force, thereby causing the first magnetic block 43 and the second magnetic block 58 to be magnetically attracted to each other, thereby limiting the position of the movable block 57 .

[0080] The other end of the stretch band 42 is connected to the first magnetic block 43. It should be noted that the first magnetic block 43 and the second magnetic block 58 can be strong magnets, so that the first magnetic block 43 and the second magnetic block 58 are magnetically attracted to each other more tightly.

[0081] Specifically, when personnel need to use this device to perform compression hemostasis on an agitated patient with severe traumatic bleeding, they first place the wound site / the area to be hemostatically controlled on the placement belt 2. The torsion bar 56 is rotated according to the location of the wound, and the position of the compression frame 59 is adjusted to converge the gas in the airbag body 521. The compression belt 51 is passed through the strip opening 71, and the position of the airbag body 521 corresponds to the area to be hemostatically controlled. The torsion bar 56 is then inserted into the matching groove 111.

[0082] Then, the retractable belt 42 is pulled, magnetically securing the first magnetic block 43 and the second magnetic block 58, ensuring the stability of the position of the pressing frame 59. The extension belt 6 is then passed through the rectangular frame 9, which moves downward and drives the mounting plate 10 to move. During this process, the restraint mechanism 3 can further apply pressure to the wound site. Simultaneously, as the connecting plate 86 moves downward, it drives the two limiting arc blocks 83 closer together, further restraining the rest of the limb.

[0083] Finally, the extension belt 6 is fixed by bonding the fleece-side Velcro 61 and the hook-side Velcro 13 to achieve restraint of the patient and pressure hemostasis at the wound site.

[0084] It should be noted that by adjusting the relative position between the fleece-side Velcro 61 and the hook-side Velcro 13 on the extension belt 6 , the pressure on the affected area can be adjusted.

[0085] In summary, the integrated limb fixation device for restraint and pressurized hemostasis of the embodiment of the present application can realize the coordinated operation of pressurized hemostasis and limb restraint, avoiding mutual interference when traditional devices are used independently. When facing patients who are agitated and accompanied by severe traumatic bleeding, the wound can be accurately pressurized to stop bleeding, and the limb can be firmly restrained at the same time, without the medical staff having to make a difficult choice between the two or frequently switch operations. It greatly saves treatment time, improves the success rate of hemostasis, reduces the difficulty and intensity of the work of medical staff, and reduces errors caused by complex operations. At the same time, sufficient restraint can prevent patients from aggravating injuries due to agitation, ensure the safety and order of the treatment process, and comprehensively improve the treatment effect and safety of patients.
