Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular to an external fixation device for fractures. Background Technology

[0002] Fracture fixation devices are commonly used auxiliary equipment in orthopedic treatment. After the fracture site is reduced, patients often need to use splints to fix it in place to assist in the recovery of the fracture. Traditional fixation devices can use ice packs for cooling, but they lack the ability to regulate temperature and have a narrow range of applications.

[0003] A search revealed a Chinese patent document (authorization announcement number CN212522157U) for an emergency limb fracture ice pack fixation device, which includes: a fracture fixation component comprising two semi-circular fixation components symmetrically arranged vertically; each fixation component includes an attachment layer, a receiving area, and an outer cover layer; the area enclosed by the two fixation components can accommodate the fractured limb; and an ice pack component, which is an ice pack disposed within the receiving area and detachably connected to the inner wall of the outer cover layer via a connecting component. This utility model provides an emergency limb fracture ice pack fixation device, which, by setting the fracture fixation component and the ice pack component, allows for rapid limb fixation and ice pack application for patients in emergency situations; achieving the dual effects of limb fixation and ice pack application. While the fixation device can utilize ice pack equipment for cooling, it lacks temperature regulation capabilities and has a narrow range of applications. Summary of the Invention

[0004] The purpose of this invention is to provide an external fixation device for fractures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an external fixation device for fractures, comprising:

[0006] Multiple hollow arc-shaped plates are used for external fixation of fractured limbs, and adjacent arc-shaped plates are connected by two rotating parts;

[0007] Multiple airbags are connected to the inner wall of multiple curved plates. The side of the airbag away from the curved plate is detachably connected to the antibacterial main layer by Velcro. Antibacterial sub-layers are connected to both sides of the antibacterial main layer.

[0008] The inner wall of the arc plate is rotatably connected to multiple rotating rods. The inner cavity of the arc plate is filled with water for heat conduction. Multiple stirring blades for stirring the water are connected to the outer periphery of the rotating rods. The inner wall of the arc plate is connected to a heating tube for heating and a semiconductor cooling chip for cooling. The side of the arc plate is connected to a water pipe with a valve.

[0009] An auxiliary belt is connected to the outer periphery of one of the arc-shaped plates. Two breathable storage bags are connected to the side of the auxiliary belt. The inner cavity of one storage bag is equipped with the heat-dissipating end of a semiconductor cooling chip, and the inner cavity of the other storage bag is equipped with an inflation component for inflating the airbag. Multiple support rods for supporting the storage bag are connected to the inner wall of the storage bag.

[0010] As a preferred embodiment, the rotating component includes two lugs that are fixedly connected to the arc-shaped plate respectively. The two lugs of the two rotating components on one side are connected to elastic bands, and the lugs of the remaining rotating components are rotatably connected by rotating rods.

[0011] As a preferred embodiment, both elastic bands are connected to pull straps, and the two corresponding pull straps are connected by adjusting buckles.

[0012] As a preferred embodiment, one of the antibacterial sublayers has a hook and loop fastener attached to one side, and the other antibacterial sublayer has a hook and loop fastener attached to one side that mates with the hook and loop fastener.

[0013] As a preferred embodiment, the antibacterial sublayer includes an absorbent layer, an antibacterial layer, a sponge layer, and a fabric layer connected in sequence, with the fabric layer connected to the airbag.

[0014] As a preferred embodiment, one of the curved plates is connected to a storage bag with an opening on one side, and the opening of the storage bag is connected by a zipper.

[0015] As a preferred embodiment, the inner wall of the storage bag is connected to an insulation layer and a waterproof layer, with the insulation layer located outside the waterproof layer. Both the insulation layer and the waterproof layer are connected to multiple first elastic bands, and the first elastic bands of the insulation layer and the waterproof layer are staggered.

[0016] As a preferred embodiment, the side of the curved plate is connected to several second telescopic belts corresponding to the positions of the first telescopic belts. The first telescopic belts and the second telescopic belts are connected by snaps, and both the first telescopic belts and the second telescopic belts are made of elastic material.

[0017] As a preferred embodiment, an inner arc plate, an outer arc plate, and two connecting plates are fixedly connected to the sides of multiple arc plates. Both connecting plates are fixedly connected to the inner arc plate and the outer arc plate. The inner arc plate, the outer arc plate, and the two connecting plates form a combination space for assembly. An arc-shaped insert block that assembles with the combination space is fixedly connected to the other side of the multiple arc plates.

[0018] As a preferred embodiment, the outer arc plate has a threaded hole on its side, and a fixing threaded rod for assembly and fixation is threaded into the threaded hole. The arc-shaped insert has a circular channel on its side for the fixing threaded rod to pass through.

[0019] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0020] This external fixation device for fractures utilizes a semiconductor cooling plate to cool the liquid inside the arc-shaped plate, achieving cold compress. By pre-shaking the arc-shaped plate or gently shaking it after it is put on, the temperature uniformity of the liquid is improved. Moreover, during the shaking process, the stirring blade rotates, changing the mixing state of the liquid and indirectly improving the uniformity efficiency. By changing the working time of the semiconductor cooling plate, the cooling range can be adjusted. If the heating element is turned on, heating can be performed. The combination of these two features can meet different usage needs and improve the adaptability.

[0021] This fracture external fixation device features an inflatable air bladder that fits snugly against the skin of the limb requiring fixation. The deformable design of the air bladder accommodates limbs of different sizes. The combination of the antibacterial main layer and the antibacterial sublayer, secured with Velcro, not only provides fixation but also allows for folding of the antibacterial sublayers for exposure and unfolding. The absorbent layers of the antibacterial main layer and the antibacterial sublayer absorb moisture, reducing the possibility of impaired fracture recovery due to lack of air permeability. The antibacterial effect of the antibacterial layer also reduces the possibility of bacterial growth near the limb. The elastic design of the foam layer provides protection.

[0022] The external fixation device for fractures has a storage bag for storage. When insulation or protection is needed, the storage bag can be opened to take out the insulation layer or waterproof layer. The first and second telescopic straps can be fixed with snaps to ensure the wrapping effect of the arc plate.

[0023] This fracture external fixation device, with its inner arc plate, outer arc plate, and two connecting plates forming a combination space for assembly, and with the arc-shaped insert block set on the other side of the arc plate, can be assembled to meet the fixation needs of different lengths;

[0024] This external fixation device for fractures not only expands its applicability but also provides protection. Attached Figure Description

[0040] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0041] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0042] Please see Figures 1 to 10 This embodiment includes:

[0043] Multiple hollow arc-shaped plates 1 are used for external fixation of fractured limbs. The size and number of arc-shaped plates 1 are selected according to actual needs. Two adjacent arc-shaped plates 1 are connected by two rotating parts 2.

Multiple support rods 12 for supporting the storage bag 11 are connected to the inner wall of the storage bag 11. The tubing and connecting wires of the semiconductor cooling chip 9 required for the inflation component are not shown.

[0047] The rotating component 2 includes two lugs 201 that are fixedly connected to the arc plate 1 respectively. The staggered cross of the two lugs 201 can ensure that the arc plate 1 deflects and can only rotate in one direction. The two lugs 201 of the two rotating components 2 on one side are connected to elastic bands 202. The lugs 201 of the other rotating components 2 are rotatably connected by rotating rods 204. The two elastic bands 202 are connected to pull straps 203. The corresponding two pull straps 203 are connected by adjusting buckles. Multiple arc plates 1 are wrapped around the limbs that need to be fixed, and two close pull straps 203 are fixed. Then, the airbag 3 is inflated by the inflator to ensure the fixation effect.

[0048] To meet usage requirements, one of the antibacterial sub-layers 5 has a hook and loop fastener attached to its side.

The inner wall of the storage bag 13 is connected to an insulation layer 22 and a waterproof layer 23. The insulation layer 22 is located outside the waterproof layer 23. Both the insulation layer 22 and the waterproof layer 23 are connected to multiple first telescopic straps 14. The first telescopic straps 14 of the insulation layer 22 and the first telescopic straps 14 of the waterproof layer 23 are staggered. The side of the curved plate 1 is connected to several second telescopic straps 15 corresponding to the positions of the first telescopic straps 14. The first telescopic straps 14 and the second telescopic straps 15 are connected by snaps. Both the first telescopic straps 14 and the second telescopic straps 15 are made of elastic material.

[0050] Multiple arc-shaped plates 1 are fixedly connected to an inner arc plate 16, an outer arc plate 17, and two connecting plates 18 on their sides. Both connecting plates 18 are connected and fixed to the inner arc plate 16 and the outer arc plate 17. The inner arc plate 16, the outer arc plate 17, and the two connecting plates 18 form a combination space for assembly. The other side of the multiple arc-shaped plates 1 is fixedly connected to an arc-shaped insert 19 that is combined with the combination space. The outer arc plate 17 has a threaded hole on its side, and a fixing threaded rod 20 for assembly is threaded into the threaded hole. The arc-shaped insert 19 has a circular channel on its side for the fixing threaded rod 20 to pass through. If assembly is required, the arc-shaped insert 19 can be inserted into the combination space and fixed by the fixing threaded rod 20 to achieve assembly.

[0051] The inflatable component, semiconductor cooling chip 9, and heating tube 8 are all existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this invention is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0052] Working principle

[0053] If the external fixation device for fractures needs to be assembled, the arc-shaped insert 19 can be inserted into the assembly space and fixed with the fixed threaded rod 20 to achieve assembly. Then, multiple arc-shaped plates 1 can be wrapped around the limb that needs to be fixed, and two adjacent straps 203 can be fixed. Then, the airbag 3 can be inflated with the inflator to ensure the fixation effect.

[0054] If cooling is required, cold water can be introduced into the arc plate 1 through the water pipe 21 in advance, or the semiconductor cooling chip 9 can be turned on to cool the water. Under the premise of ensuring safety, the arc plate 1 can be shaken to mix the water and achieve uniform cooling.
