Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and provides a light-cured fracture first aid fixation splint which is convenient for first aid, easy to operate, simple in structure and takes a short time. Background Art

[0002] Limb fractures are common combat injuries. Beyond maintaining vital signs and managing bleeding, the most important first aid measure is immobilization using appropriate equipment. The goal of immobilization is to prevent further displacement of the fractured bones and minimize damage to surrounding tissue. First aid immobilization materials, including SAM boards, are primarily used, but attention must be paid to stability and comfort. However, most first aid splints lack conformability to the limb's shape, lack ventilation, provide insufficient fixation, and are difficult to shape. These shortcomings prevent the splint from maintaining proper contact with the fractured bones during use, and can cause severe pain due to compression during shaping and placement. Furthermore, the splint's poor fit can cause discomfort, and the lack of a secure placement for the straps can lead to loosening and poor stability, potentially causing secondary injury. Furthermore, splints are airtight and completely enclosed, obscuring the wound's condition and hindering further observation, complicating ongoing treatment.

[0003] Chinese Patent 2023104347246 discloses a visible light-cured orthopedic splint, a method for preparing the splint, and an adjustable tightness splint device. The splint has a porous structure that facilitates air circulation between the skin and the outside world. After cleaning, the porous structure can also be used to quickly dry the contact area between the splint and the skin. However, the resin splint required for this invention is relatively cumbersome to prepare, has a relatively complex structure, and requires high production standards. It requires mold support and requires the combined application of different levels of accessories. The operation takes a long time and is not suitable for long-term wear and fixed use. If it is produced at the scene of a fracture, the production conditions are lacking, and the first aid purpose cannot be achieved. It is not suitable for on-site first aid and fixed use.

[0004] In summary, it is necessary to design a splint for on-site first aid that is easy to operate, simple in structure, and takes less time, on the basis of reliable and comfortable fixation. Utility Model Content

[0031] like Figures 1 to 6 As shown, the light-cured fracture emergency fixation splint of the present invention comprises a splint 1 made of light-cured resin, the splint 1 being in a mesh shape, with a fixing ring 2 for fixing a sling on a long side of the splint 1; wherein: the splint 1 is composed of two pieces, and a buffer sponge 3 for buffering the fracture end is provided between the two splints 1;

[0032] The reinforcing wire 4 passing through the splint 1 and the cushioning sponge 3 fixes the two splints 1 and the cushioning sponge 3 into one body to form a fixed splint body 5. The reinforcing wire 4 is also used to assist in shaping the fixed splint body 5.

[0033] A layer of light-shielding film 6 is provided on the outer surface of the splint 1, and the light-shielding film 6 is used to shield visible light and prevent the splint 1 made of photocurable resin from solidifying. In this embodiment, the reinforcing wire 4 is a metal wire that can be deformed under the action of external force, such as a copper wire or a soft steel wire. There are three reinforcing wires 4, which are used to fix the shape and shape of the splint body 5. In this embodiment, the length of the splint 1 is 20.0 cm and the width is 11.0 cm. The area of ​​the light-shielding film 6 can at least cover the top and bottom surfaces of the entire splint 1, and the material has light-shielding and heat-insulating effects. If cold weather or water environment is required, the injured limb can be wrapped with the light-shielding film 6 again after the splint body 5 is fixed to achieve heat-insulating and waterproof effects. The best way is that the light-shielding film 6 wraps the entire fixed splint body 5.

[0034] To cushion the injured area during first aid, in the above embodiment, preferably, a sponge layer 7 is provided on the bottom surface of the splint 1. In this embodiment, at least one sponge layer 7 is provided, and during installation, the breathability of the splint 1 must be ensured. In this embodiment, the light-shielding film 6 wraps around the sponge layer 7.

[0035] In order to ensure the air permeability of the fixed splint body 5, in the above embodiment, preferably, the sponge layer 7 is mesh-shaped and matches the splint 1. In this embodiment, the thickness of the sponge layer 7 is 2 cm.

[0036] To ensure the assembly of the clamping plate 1 and the fixing ring 2, in the above embodiment, preferably, the fixing ring 2 is fixed to the clamping plate frame 10 as a whole, and the clamping plate frame 10 is fixed to the long side of the clamping plate 1. In this embodiment, the clamping plate frame 10 and the fixing ring 2 are both made of metal, and the through hole in the fixing ring 2 can be circular or rectangular, or other polygonal shapes.

[0037] To facilitate securing the splint 1 during first aid, in the above embodiment, preferably, a securing strap 8 is secured to the securing ring 2. In this embodiment, the corners of the securing ring 2 are rounded to prevent scratches on the patient. The securing strap 8 may be a Velcro strap.

[0038] In order to provide joint protection and cushioning during fixation and improve protection and cushioning of angled fracture ends, in the above embodiment, preferably, the cushioning sponge 3 is in the shape of a fence. In this embodiment, the cushioning sponge 3 is a strip of high-elasticity sponge with a thickness of 2 cm, a longitudinal dimension of 5.0 cm, and a transverse dimension of 11.0 cm.

[0039] To facilitate the shaping of the splint 1, in the above embodiment, preferably: the splint 1 is located in a photosensitive resin sleeve 9. In this embodiment, the splint 1 is formed into a mesh of strips of resin, and the strips are wrapped in the photosensitive resin sleeve 9, which facilitates subsequent light shaping, so that the fixed splint body 5 forms a support shape for the fracture.

[0040] All components in the above embodiments are commercially available products.

[0041] The first aid process of the structure described in the above embodiment is: after the first aid personnel tear off the shading film 6, the fixed splint body 5 begins to roll inward and shape according to the fracture site to fit the injured limb. The buffer sponge 3 located in the middle of the fixed splint body 5 can be placed in contact with the joint or the fracture end. After 1-2 minutes, it begins to solidify in the sun (ultraviolet light can be used for curing at night). After the fixed splint body 5 is solidified, the fixed sling 8 is used to pass through the fixed ring 2. On the one hand, the two sides of the splint 1 of the fixed splint body 5 are rolled inward so that the splint 1 fits the injured limb and is firmly fixed. On the other hand, the fixed sling 8 is used to pass through the fixed ring 2 to suspend the injured limb in front of the chest. The structure described in this scheme can not only fit the angular deformity of the injured limb, but also facilitate shaping and solidification. It is suitable for on-site emergency fixation of the injured limb; and during the transport process, the shape of the injured limb is maintained to the maximum extent, the injured limb is fixed, and secondary injuries are reduced. The whole process is completed in about 3 minutes.
