Description

Technical Field

[0001] The present invention relates to the technical field of nursing splints, and particularly to a nursing splint for leg bone fracture reduction based on medical orthopedic nursing. Background Art

[0002] Clinically, when a fracture occurs, external fixation is usually required. For example, in the case of a leg fracture, a nursing splint or plaster is needed for fixation. The purpose of using a splint for fixation is mainly to ensure the stability of the fracture ends, reduce the displacement of the fracture, ensure reduction, and at the same time promote functional recovery and reduce stiffness of adjacent joints.

[0003] A patent with the publication number CN219501302U discloses an anti-slip splint for calf fractures, which includes an upper splint and a lower splint. An upper support groove is formed on the lower end surface of the upper splint, and a lower support groove is formed on the upper end surface of the lower splint. One side of the upper splint is connected to one side of the lower splint through a hinge shaft. An upper pressing plate assembly is arranged inside the upper support groove, and a lower pressing plate assembly is arranged inside the lower support groove. A support frame is arranged below the lower splint. One end of the first elastic binding band is fixed to the upper end surface of the upper splint, and one end of the second elastic binding band is fixed to the lower end surface of the lower splint. The other ends of the first elastic binding band and the second elastic binding band are provided with mutually adhesive magic tapes.

[0004] For the above anti-slip splint for calf fractures, the patient's calf is first placed between the upper splint and the lower splint, and then the upper splint and the lower splint are bound and fixed through the first elastic binding band and the second elastic binding band, which improves the healing effect of the calf fracture. However, this device binds and fixes the splint by winding the elastic binding band around many times, and the fixing method is relatively cumbersome, making the installation and disassembly of the splint inconvenient. Moreover, during the patient's recovery process, there is a state of swelling to subsiding swelling, but the splint cannot adjust the tightening force, resulting in the splint becoming loose and affecting the fixing effect. During this period, if the fracture has not fully recovered, it is usually necessary to first remove the splint and then use a bandage for secondary fixation, which may cause secondary damage to the patient's fracture site and is not conducive to the patient's recovery. Therefore, it is necessary to develop a nursing splint for leg bone fracture reduction based on medical orthopedic nursing, which has the function of adjusting the tightening and is convenient for fixing and disassembling.

Detailed implementation manners

[0037] The following describes the implementation manners of the present invention with reference to the accompanying drawings.

[0038] Embodiment 1

[0039] A nursing splint for leg bone fracture reduction based on medical orthopedic care, as Figure 1 and Figure 2As shown in the figure, it includes a first airbag splint 1, a second airbag splint 2, an air inlet pipe 3, a reinforcement mechanism 4 and a pressing mechanism 5. The first airbag splint 1 and the second airbag splint 2 are symmetrically arranged left and right. Grooves are provided on both the left and right sides of the first airbag splint 1 and the second airbag splint 2. The number of air inlet pipes 3 is two, and the air inlet pipes 3 are respectively connected to the upper parts of the sides of the first airbag splint 1 and the second airbag splint 2 that are far away from each other. A cover is threadedly connected to the air inlet pipe 3. A reinforcement mechanism 4 is provided between the first airbag splint 1 and the second airbag splint 2. The reinforcement mechanism 4 can be used to fix the nursing splint on the patient's leg. A pressing mechanism 5 is provided on the reinforcement mechanism 4. The pressing mechanism 5 can be used to make the first airbag splint 1 and the second airbag splint 2 press tightly against the leg.

[0040] As Figure 1 , Figure 3 and Figure 4 shown, the reinforcement mechanism 4 includes fixed arc-shaped blocks 41, connecting frames 42, fixed rods 43, first arc-shaped splints 44, first springs 45, first fixed seats 46, sliding columns 47, clamping plates 48, second springs 49 and clamping seats 410. The number of fixed arc-shaped blocks 41 is four, and the fixed arc-shaped blocks 41 are respectively connected to the upper and lower sides of the first airbag splint 1 and the second airbag splint 2. The number of connecting frames 42 is two, and the connecting frames 42 are respectively connected to the right parts of the left fixed arc-shaped blocks 41. The number of fixed rods 43 is also two, and the fixed rods 43 are respectively connected to the left parts of the right fixed arc-shaped blocks 41. The connecting frames 42 are rotatably connected to the adjacent fixed rods 43. The number of first arc-shaped splints 44 is four, and the first arc-shaped splints 44 are respectively slidably connected to the middle parts of the fixed arc-shaped blocks 41. First springs 45 are connected between the first arc-shaped splints 44 and the adjacent fixed arc-shaped blocks 41. The number of first fixed seats 46 is two, and the first fixed seats 46 are respectively connected to the upper and lower parts on the left side of the first airbag splint 1. Sliding columns 47 are slidably connected in the first fixed seats 46. Second springs 49 are connected to both the left and right parts of the sides of the sliding columns 47 that are close to each other. The ends of the second springs 49 are connected to clamping plates 48. The number of clamping seats 410 is two, and the clamping seats 410 are respectively connected to the upper and lower parts on the right side of the second airbag splint 2. Clamping holes are provided in the clamping seats 410. When it is necessary to fix the patient's leg, first close the first airbag splint 1 and the second airbag splint 2 inward, and the clamping plates 48 are in pressing fit with the adjacent clamping seats 410.

[0041] As Figure 1 , Figure 5 and Figure 6As shown in the figure, the pressing mechanism 5 includes a first connecting plate 51, a first gear 52, a fixing frame 53, a first rack 54, a second rack 55 and a pressing frame 56. The number of the first connecting plates 51 is two, and the first connecting plates 51 are respectively fixedly connected to the middle parts of the upper fixing arc-shaped blocks 41. A first gear 52 is rotatably connected to the first connecting plate 51. Fixing frames 53 are connected to the left and right sides of the middle part of the first connecting plate 51. The number of the first racks 54 is four, and the first racks 54 are respectively connected to the mutually remote sides of the first arc-shaped clamping plates 44. The first racks 54 are slidably connected to the adjacent fixing frames 53. The number of the second racks 55 is also four, and the second racks 55 are respectively slidably connected in the left fixing frames 53. Both the first racks 54 and the second racks 55 are meshed with the adjacent first gears 52. A pressing frame 56 is connected between two of the second racks 55 adjacent to the first airbag clamping plate 1, and another pressing frame 56 is also connected between two of the second racks 55 adjacent to the second airbag clamping plate 2. The pressing frame 56 is arranged in a semi-circular arc shape that is conducive to fitting with the first airbag clamping plate 1 and the second airbag clamping plate 2.

[0042] When the device is in use, the medical staff first wraps the device around the patient's leg, allowing the first airbag splint 1 and the second airbag splint 2 to close inward, thereby driving the sliding column 47 to contact the clamping seat 410, and then causing the clamping plate 48 to slide into the clamping hole of the clamping seat 410. The clamping seat 410 will squeeze the clamping plate 48 to move it inward, and the second spring 49 will be deformed. When the clamping plate 48 passes through the clamping hole of the clamping seat 410, under the elastic action of the second spring 49, the clamping plate 48 moves outward and resets. At this time, the sliding column 47 has been clamped on the clamping seat 410 through the clamping plate 48, so that the splint is installed on the patient's leg. At the same time, the leg will also squeeze the first arc-shaped splint 44 to move it outward. The first spring 45 The first airbag splint 1 and the second airbag splint 2 are deformed so that the nursing splint does not move up and down. Then, the cover on the air inlet pipe 3 is unscrewed, and an appropriate amount of gas is filled into the first airbag splint 1 and the second airbag splint 2 to make the first airbag splint 1 and the second airbag splint 2 bulge, thereby generating a squeezing force on the leg, which plays a role in fixing the patient's fracture end. When the gas is filled, the cover is tightened again. When the first arc-shaped splint 44 moves outward, it will drive the first rack 54 to move outward, thereby driving the clamping frame 56 to move inward through the first gear 52 and the second rack 55. The clamping frame 56 moving inward will tighten the first airbag splint 1 and the second airbag splint 2, so that the first airbag splint 1 and the second airbag splint 2 are fixed to the leg. When the patient's leg is fully recovered and the splint can be removed, first unscrew the cover of the air intake pipe 3 to deflate the air, then pinch the card plate 48 to bring it closer to the inside, then pull the sliding column 47 outward to separate it from the card seat 410, and the second spring 49 will first deform and then reset. Then the nursing splint can be removed from the patient's leg. At the same time, under the elastic action of the first spring 45, the first arc-shaped splint 44 will move inward and reset, thereby making the pressing frame 56 move outward and reset through the first rack 54, the first gear 52 and the second rack 55. In summary, the installation and disassembly of the nursing splint are made more convenient by cooperating with the clamping plate 48 and the clamping seat 410. Secondly, by adjusting the air pressure in the first airbag splint 1 and the second airbag splint 2, there is no need to remove the splint when the patient's swelling subsides, avoiding secondary injury and being not conducive to the patient's recovery. Then, the first airbag splint 1 and the second airbag splint 2 are made closer to the patient's leg through the pressing frame 56, thereby improving the fixing effect of the splint.

[0043] Example 2

[0044] On the basis of Example 1, Figure 1 、Figure 7 and Figure 8 As shown, it also includes a liquid discharge mechanism 6, which can be used to squeeze glue into the groove of the second airbag splint 2, and the liquid discharge mechanism 6 includes a second fixed seat 61, a glue tank 62, a liquid discharge pipe 63, a wedge frame 64 and a third spring 65. The number of the second fixed seat 61 is two, and the second fixed seat 61 is respectively connected to the left and right parts of the upper right fixed arc block 41, the top of the second fixed seat 61 is connected to the glue tank 62, and the right wall of the glue tank 62 is connected to the liquid discharge pipe 63, and the number of the wedge frames 64 is two, and the wedge frames 64 are respectively slidably connected to the bottom wall of the glue tank 62, and the wedge frames 64 are also slidably connected to the adjacent second fixed seat 61, and a third spring 65 is connected between the lower part of the wedge frame 64 and the adjacent second fixed seat 61. When the first airbag splint 1 and the second airbag splint 2 are closed inward, the two fixed arc blocks 41 on the upper side are squeezed and fitted with the wedge frames 64.

[0045] When the first airbag splint 1 and the second airbag splint 2 are closed inward, the two upper fixed arc blocks 41 are also closed inward. The two upper fixed arc blocks 41 squeeze the wedge frame 64 to move it upward. The third spring 65 is deformed. The upward moving wedge frame 64 compresses the space in the glue tank 62, increasing the pressure in the glue tank 62. The glue in the glue tank 62 is squeezed out into the groove of the second airbag splint 2 through the liquid outlet pipe 63, so that the first airbag splint 1 and the second airbag splint 2 are closed. During the process, it will be pasted first, which not only allows the nursing splint to be initially fixed to the patient's leg, but also ensures that there is no gap between the first airbag splint 1 and the second airbag splint 2 after installation. Furthermore, when fixing the injured part, the extrusion force is evenly distributed on the leg, thereby improving the fixing effect of the nursing splint. When removing the nursing splint from the patient's leg, first use a tool to cut open the adhesive part of the first airbag splint 1 and the second airbag splint 2, and under the elastic action of the third spring 65, the wedge frame 64 moves downward to reset.

[0046] like Figure 1 、 Figure 9 and Figure 10As shown, it also includes a reinforcing mechanism 7, which can be used to further clamp the legs of the first airbag splint 1 and the second airbag splint 2. The reinforcing mechanism 7 includes a second connecting plate 71, a fixing pin 72, a second arc splint 73 and a fourth spring 74. There are two second connecting plates 71, and the second connecting plates 71 are respectively connected to the top of the glue box 62. The second connecting plates 71 are slidably connected with the second arc splint 73, and the second arc splint 73 is provided with a socket. There are two fixing pins 72, and the fixing pins 72 are respectively connected to the upper part of the wedge frame 64. A fourth spring 74 is connected between the second arc splint 73 and the adjacent second connecting plate 71. The fourth spring 74 is wound around the adjacent second arc splint 73. In the normal state, the fourth spring 74 is in a deformed state, and the fixing pins 72 are also inserted into the socket of the adjacent second arc splint 73.

[0047] When the support leg is in the closed position, the locking yoke 72 is in a locked state, and the locking yoke 73 is in a locked state when the support leg is in the locked state.

[0048] like Figure 1 、 Figure 11 、 Figure 12 and Figure 13 As shown, it also includes a scratching mechanism 8, which can be used to scratch the patient's legs when they are itchy. The scratching mechanism 8 includes a third fixed seat 81, a motor 82, a second gear 83, a screw rod 84, a third gear 85 and a scratching plate 86. There are two third fixed seats 81, and the third fixed seats 81 are respectively connected to the upper left part of the upper fixed arc block 41. The third fixed seat 81 is equipped with a motor 82, and the output shaft of the lower side of the motor 82 is connected to the second gear 83 through a coupling. There are two third gears 85, and the third gears 85 are respectively rotatably connected to the third fixed seat 81. The third gear 85 is meshed with the adjacent second gear 83. There are two screw rods 84, and the screw rods 84 are respectively threadedly connected to the third gear 85. The bottom of the screw rod 84 is connected to a scratching plate 86, and the two scratching plates 86 are respectively close to the inner sides of the first airbag splint 1 and the second airbag splint 2.

[0049] When the patient's leg is itchy during the swelling reduction process, first start the motor 82, control the output shaft of the motor 82 to drive the second gear 83 to rotate, thereby driving the screw rod 84 to move up and down through the third gear 85, and then driving the scratching plate 86 to move upward. The scratching plate 86 moving up and down will gently scratch the leg, relieve the patient's skin itching, make the patient feel comfortable, and promote the patient's recovery. When the itching disappears, just turn off the motor 82.

[0050] As Figure 1 , Figure 14 and Figure 15 shown, it further includes a protection mechanism 9. The protection mechanism 9 can be used to prevent the first airbag splint 1 and the second airbag splint 2 from being hit by foreign objects. The protection mechanism 9 includes a third connecting plate 91, a protection frame 92 and a fifth spring 93. The number of the third connecting plates 91 is four. Every two third connecting plates 91 are respectively connected to the upper fixed arc-shaped blocks 41. The number of the protection frames 92 is two. One protection frame 92 is slidably connected between the upper and lower parts of the two left third connecting plates 91, and the other protection frame 92 is slidably connected between the upper and lower parts of the two right third connecting plates 91. Both the upper and lower parts of the protection frame 92 are symmetrically connected to the adjacent third connecting plates 91 on the left and right by fifth springs 93. The fifth springs 93 are wound around the adjacent protection frames 92.

[0051] When a foreign object hits this nursing splint, it will cause the protection frame 92 to move inward, and the fifth spring 93 will deform. After the impact ends, under the elastic action of the fifth spring 93, the protection frame 92 will move outward and reset. To sum up, the protection frame 92 can protect the first airbag splint 1 and the second airbag splint 2 from being hit by external forces, thereby avoiding harm to the patient's leg and improving the protection performance of the device.

[0052] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, are equally included in the patent protection scope of the present invention.
