Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly to a vehicle-mounted portable clinical fixation device for limb fractures. Background Art

[0002] Fracture is a common injury. Every year, millions of cases of fracture surgery and internal fixation are performed worldwide. Internal fixation is to reposition the fracture and then connect the fractured parts with steel plates and screws. When a patient is injured and the bones are damaged, the doctor needs to fix the affected area with a splint after diagnosis and treatment to facilitate the healing of the affected area.

[0003] Existing in-vehicle emergency equipment often lacks fixation devices specifically for lower limb fractures. The commonly used external fixation method is generally to use plaster to fix the patient's fracture. The plaster fixation steps are too cumbersome and have poor air permeability, which is very inconvenient during use. Moreover, it is disposable and cannot be adjusted or recycled. After recovery, it is too troublesome to remove the plaster.

[0004] To solve the above problems, the prior art has proposed relevant solutions, such as the fracture fixation device with authorization announcement number CN106108993B, which mainly fixes the legs through three splints. However, during the fixation process, the splints are always in contact with the skin of the legs.

[0047] like Figures 1 to 9 As shown, an embodiment of the present invention provides a vehicle-mounted portable clinical fixation device for limb fractures, including a fixing frame 1, two fixing frames 1 are provided, a slot 3 is provided in the middle of the outer surface of the fixing frame 1, locking plates 2 are evenly provided on the edge of one end of the fixing frame 1, and clamping components 4 for fixing the legs are connected to the edges on both sides of the outer surface of the fixing frame 1.

[0048] like Figure 2 and Figure 3As shown, the clamping assembly 4 includes two support plates 41 fixed on the outer surface of the fixed frame 1, and the first telescopic rod 42 and the second telescopic rod 43 are slidably connected inside one support plate 41, the bottom of the first telescopic rod 42 is fixedly connected to the clamping plate 44, and the bottom of the second telescopic rod 43 is fixedly connected to the rectangular frame 45, and the other support plate 41 is slidably connected to the drive shaft 411, and the bottom of the drive shaft 411 is fixedly connected to the third gear 415. The outer surface of the drive shaft 411 is sleeved with a second spring 410, and the first and second internally threaded sleeves 412 and 413 are rotatably connected on both sides of the interior of the support plate 41, and the outer surfaces of the first and second internally threaded sleeves 412 and 413 are respectively sleeved with a second gear 414 and a fourth gear 416, the internal thread of the second internally threaded sleeve 413 is connected to the second threaded rod 49, and the internal thread of the first internally threaded sleeve 412 is connected to the first threaded rod 48.

[0049] The third gear 415 is meshed with the second gear 414 and the fourth gear 416. The bottom of the first threaded rod 48 is fixedly connected to the upper surface of the rectangular frame 45. The bottom of the second threaded rod 49 is fixedly connected to the upper surface of the splint 44. The top of the drive shaft 411 is fixedly connected to the limiting plate. The second spring 410 is located between the support plate 41 and the limiting plate. The middle of the upper surface of the splint 44 is connected to the massage component 46. The two sides of the top of the splint 44 are connected to the cold compress components 47 for cooling. The inside of the rectangular frame 45 is adapted to the splint 44. The middle of the two ends of the outer surface of the fixed frame 1 is connected to the application component 5.

[0050] When fixing the patient's lower limbs, the two fixing frames 1 are put on the fracture site, and the threaded holes on the two locking plates 2 are fixed to them by locking screws to fix the two fixing frames 1. At this time, the driving shaft 411 is lifted upward to drive the third gear 415 to move to the same level as the second gear 414, and the third gear 415 and the second gear 414 are meshed with each other. The rotating driving shaft 411 drives the first internally threaded sleeve 412 to rotate through the third gear 415 and the second gear 414. The first internally threaded sleeve 412 drives the first threaded rod 48 and the rectangular frame 45 to move toward the leg through the thread. After completing the clamping of the four rectangular frames 45, the driving shaft 411 is pressed again to drive the third gear 415 to engage with the fourth gear 416, and the rotating driving shaft 411 drives the second internally threaded sleeve 413 to rotate through the transmission, thereby driving the second threaded rod 49 and the splint 44 to approach the patient's leg for clamping, so that the four rectangular frames 45 and the splint 44 effectively clamp the leg.

[0051] After a period of fixed clamping, the skin squeezed by the splint 44 and the rectangular frame 45 for a long time will have poor blood flow, congestion, and even pressure sores. At this time, the third gear 415 can be engaged with the fourth gear 416 to drive the splint 44 to move away from the skin, exposing the skin pressed by the splint 44 to air, so that the poor blood flow in the area pressed by the splint 44 is improved, avoiding the occurrence of pressure sores. After a period of time, the splint 44 is clamped on the leg again, and the third gear 415 is engaged with the second gear 414 to drive the rectangular frame 45 to move, and the skin pressed by the rectangular frame 45 is exposed to air. The skin is also exposed, which relieves the blood flow obstruction in the compressed area. Therefore, when the patient's leg is fixed, the fixed area can be flexibly adjusted to avoid long-term pressure on the skin in the local area, reduce blood stasis and bruises caused by poor blood flow, and even pressure sores, effectively improving the comfort of the fixation device. When idle, the third gear 415 is not engaged with the second gear 414 and the fourth gear 416, effectively preventing the drive shaft 411 from being accidentally rotated, causing the third gear 415 to rotate, thereby causing the splint 44 and the rectangular frame 45 to move, resulting in an insufficient clamping effect and even affecting bone growth.

[0052] like Figure 4 - Figure 7 As shown, the massage component 46 includes a first servo motor 461 fixed on the upper surface of the splint 44, a slide plate 462 slidably connected to the top inner side of the splint 44, and two groups of receiving grooves 466 opened on both sides of the lower surface of the splint 44, the output end of the first servo motor 461 is fixedly connected to the first gear 467, the upper surface of the slide plate 462 is fixedly connected to the rack 468, and a plurality of arc-shaped protrusions 463 are evenly fixedly connected on both sides of the lower surface of the slide plate 462, the interior of the receiving groove 466 is slidably connected to a hollow T-shaped massage block 464, the outer surface of the hollow T-shaped massage block 464 is fixedly connected to a ring 469 near the top, the outer surface of the hollow T-shaped massage block 464 is sleeved with a first spring 465, and the two locking plates 2 are fixed by locking screws.

[0053] The output end of the first servo motor 461 extends to the interior of the splint 44, the first gear 467 and the rack 468 are engaged with each other, the first spring 465 is located inside the splint 44 and below the ring 469, the top of the first spring 465 is fixedly connected to the ring 469, and the bottom of the first spring 465 is supported on the bottom of the splint 44. The arc-shaped protrusion 463 corresponds one-to-one to the hollow T-shaped massage block 464, and the storage groove 466 on the same side is a group.

[0054] When the splint 44 and the rectangular frame 45 press the patient's legs, although the poor blood flow is alleviated by adjusting the pressing area, the poor blood flow still exists. Therefore, the splint 44 can be lifted upward to expose the skin pressed by the splint 44. At the same time, the rectangular frame 45 remains fixed, and the first servo motor 461 is turned on to drive the first gear 467 to rotate and drive the rack 468 to move linearly. The rack 468 drives the slide plate 462 to move back and forth in a linear direction, driving the arc-shaped protrusion 463 to move toward the hollow T-shaped massage block 464, and the arc-shaped protrusion 463 moves toward the hollow T-shaped massage block 464. The arc surface of the protrusion 463 contacts the top of the hollow T-shaped massage block 464 and pushes the hollow T-shaped massage block 464 out of the inside of the splint 44. The hollow T-shaped massage block 464 massages the patient's legs. When the arc-shaped protrusion 463 moves back, the first spring 465 drives the hollow T-shaped massage block 464 to reset. This cycle allows the hollow T-shaped massage block 464 to continuously press and massage the legs, effectively promoting blood circulation in the patient's legs. During the massage, it can help the patient relax and accelerate physical recovery.

[0055] like Figure 4 and Figure 6 As shown, the cold compress assembly 47 includes water inlet and outlet pipes 473 fixed on both sides of the top of the splint 44, one end of the two water inlet and outlet pipes 473 is connected to a hose 472, and the ends of the two hoses 472 close to each other are connected to a guide pipe 471, and the outer surface of the guide pipe 471 is evenly connected with two groups of diversion pipes 474, and the other side of the diversion pipe 474 is interconnected with the outer surface of the hollow T-shaped massage block 464.

[0056] The guide pipe 471 is located between the two groups of receiving grooves 466, and the diversion pipe 474 corresponds to the hollow T-shaped massage block 464 one by one.

[0057] At the beginning of the fracture, the patient's leg is injured, causing local pain. At this time, cold water is passed into the inlet and outlet pipes 473. The cold water enters the interior of the diversion pipe 471 through the inlet and outlet pipes 473 and the hose 472, and then flows from the inlet and outlet pipes 473 to multiple diversion pipes 474, and finally enters the interior of the hollow T-shaped massage block 464. Since the splint 44 fits the skin, the bottom of the hollow T-shaped massage block 464 is also in contact with the skin. The cold water in the hollow T-shaped massage block 464 is used to cool the fracture area, shrink local capillaries, reduce capillary bleeding and exudation, as well as exudation of surrounding tissue fluid, reduce edema, prevent the occurrence of severe edema, and effectively relieve the patient's pain.

[0058] like Figure 8As shown, the smearing component 5 includes a C-shaped plate 51 fixed at the middle of the two ends of the outer surface of the fixed frame 1, and a first through groove 54 is opened on both sides of the upper surface of the C-shaped plate 51, and a second through groove 55 is opened in the middle of the upper surface of the C-shaped plate 51. A second servo motor 52 is fixedly connected to one side of the C-shaped plate 51, and the output end of the second servo motor 52 is fixedly connected to a third threaded rod 56. The outer surface of the third threaded rod 56 is threadedly connected to a connecting plate 57, and the top of the connecting plate 57 is fixedly connected to a feeding frame 53. Adjustment components 59 are connected to both sides of the lower surface of the feeding frame 53. A rotary joint 510 is connected to the adjustment component 59. The side of the rotary joint 510 close to each other is connected to a liquid inlet pipe 511. A sponge roller 58 is provided on the outer surface of the liquid inlet pipe 511, and a plurality of liquid outlet holes 512 are opened on the inner side of the liquid inlet pipe 511.

[0059] The connecting plate 57 slides inside the second through slot 55 , the feeding frame 53 is located above the C-shaped plate 51 , and the adjusting component 59 slides inside the first through slot 54 .

[0060] When the patient wears the device, the patient's legs will be swollen and painful. When hot compress or cold compress cannot reduce the swelling and relieve the pain, analgesic and swelling-reducing liquid can be added to the inside of the feed frame 53. The liquid medicine enters the liquid inlet pipe 511 through the adjustment component 59, and then enters the inside of the sponge roller 58 through the liquid outlet 512. When the sponge roller 58 is completely soaked with the liquid medicine, the second servo motor 52 is turned on to drive the third threaded rod 56 to rotate. The third threaded rod 56 drives the connecting plate 57 and the feed frame 53 to move, thereby driving the sponge roller 58 to move and roll on the patient's legs. During the rolling process, the liquid medicine is evenly applied to the legs. The movement of the sponge roller 58 on the legs can not only massage the patient's legs, but also effectively promote the skin's absorption of the liquid medicine, thereby relieving the patient's leg pain as soon as possible.

[0061] like Figure 9 As shown, the adjustment assembly 59 includes a second sleeve 592 fixed on the lower surface of the feed frame 53, the outer surface of the second sleeve 592 is sleeved with a first sleeve 591, and one side of the first sleeve 591 and the second sleeve 592 are respectively fixedly connected with a mounting plate 593, and the internal thread of the mounting plate 593 is connected with a fourth threaded rod 594.

[0062] One side of the first sleeve 591 is interconnected with the rotary joint 510, the top of the second sleeve 592 is interconnected with the lower surface of the feed frame 53, the second sleeve 592 is interconnected with the interior of the feed frame 53, and the first sleeve 591, the second sleeve 592, the rotary joint 510 and the liquid inlet pipe 511 are interconnected.

[0063] However, the sponge roller 58 is not always in full contact with the patient's legs. In this case, the position of the sponge roller 58 needs to be adjusted. The fourth threaded rod 594 is rotated to drive the mounting plate 593 on the first sleeve 591 to move through the thread, so that the first sleeve 591 drives the sponge roller 58 to adjust its position to ensure that the sponge roller 58 is in full contact with the patient's legs and that the legs can be smoothly pressed by the sponge roller 58.

[0064] The working process of the present invention is as follows:

[0065] First, by providing a clamping component 4, the positions of the splint 44 and the rectangular frame 45 can be adjusted, and the skin pressed by the splint 44 and the rectangular frame 45 can be exposed and breathable in turn to avoid the occurrence of pressure sores. At the same time, with the cooperation between the various components of the massage component 46, the patient's legs can be massaged, which can promote the accelerated flow of blood and relieve pain. The cold compress component 47 starts to flow cold water at the beginning of the fracture, and applies a cold compress to the patient's skin through the hollow T-shaped massage block 464, which can prevent subsequent severe swelling of the legs.

[0066] Then, the second servo motor 52 and the third threaded rod 56 cooperate with each other to drive the sponge roller 58 soaked in the medicine to roll back and forth on the patient's legs, evenly applying the medicine to the legs to promote the absorption of the medicine by the legs. The position of the sponge roller 58 can be adjusted by the adjustment component 59 so that the sponge roller 58 is always in contact with the legs, thereby improving practicality.

[0067] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. While specific details are described in detail in the preferred embodiments to provide a thorough understanding of the present invention, those skilled in the art will be able to fully understand the present invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
