DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as "set", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0020] Embodiment 1: A breathable polymer fixing splint for fractures. Refer to Figures 1 - 3 As shown in the figure, it includes a splint body polymer fiber layer 1, a splint body polyurethane layer 2, and a fixing component. The splint body polyurethane layer 2 is disposed inside the splint body polymer fiber layer 1 by bonding. The splint body polymer fiber layer 1 and the splint body polyurethane layer 2 together form the splint body. A fixing component for fixing the splint body on the patient's limb part is provided on the splint body polymer fiber layer 1. It also includes a water storage bag 3, an infusion tube 4, and a screw cap 5. The water storage bag 3 is fixedly connected inside the splint body polymer fiber layer 1 by sewing. One side of the lower part of the water storage bag 3 is connected and communicated with the infusion tube 4. The infusion tube 4 penetrates to the outside of the splint body polymer fiber layer 1, and a screw cap 5 is threadedly provided on the infusion tube 4.

[0021] Refer to Figure 3 As shown in the figure, the fixing component includes three connecting bands 6 distributed up and down and fixedly connected to one side of the splint body polymer fiber layer 1 by sewing. Three first adhesive blocks 7 are fixedly connected to the connecting bands 6 by sewing. Three second adhesive blocks 8 are fixedly connected to the other side of the splint body polymer fiber layer 1 by sewing. The first adhesive blocks 7 and the second adhesive blocks 8 are adhesively engaged.

[0022] When a polymer splint is needed, first immerse the polymer fiber layer 1 of the splint body and the polyurethane layer 2 of the splint body in water. Then wrap the polymer fiber layer 1 of the splint body around the fractured limb part of the patient, and use the connecting band 6 to surround the polymer fiber layer 1 of the splint body and the patient's limb to bond and fix the first bonding block 7 and the second bonding block 8. Then wait for drying. After the polymer fiber layer of the splint body and the polyurethane layer 2 of the splint body are dried, they solidify into a block to fix the patient's fracture. When the splint body solidifies into a block, pores will be formed on both the polymer fiber layer of the splint body and the polyurethane layer 2 of the splint body to make it have good air permeability. When it is necessary to raise the temperature of the limb wrapping part, turn the screw cap 5 to open it, and add hot water into the water storage bag 3 through the infusion tube 4. The hot water conducts heat to the fractured limb part through the water storage bag 3 and the polymer fiber layer 1 of the splint body to cool the patient's limb part. When it is necessary to lower the temperature of the limb wrapping part, just add cold water into the water storage bag 3 through the infusion tube 4 to make the cold water absorb and take away the heat on the limb.

[0023] Embodiment 2: On the basis of Embodiment 1, refer to Figure 4 As shown, it further includes an antipruritic patch 9 for relieving itching, which is fixedly connected to the inner side of the polymer fiber layer 1 of the splint body by pasting.

[0024] When the polymer fiber layer 1 of the splint body fits the human body for a long time, the human skin will itch. At this time, the antipruritic patch 9 can reduce the itching sensation and avoid discomfort.

[0025] Refer to Figure 4 As shown, moisture-proof papers 10 for moisture-proof and water absorption are fixedly connected to both sides of the polyurethane layer 2 of the splint body by pasting.

[0026] When there is humid water vapor, the moisture-proof paper 10 can absorb the moisture to prevent the polyurethane layer 2 of the splint body from reacting when it encounters water. When the polymer fiber layer 1 of the splint body together with the polyurethane layer 2 of the splint body is immersed in water, the water can still react with water after the moisture-proof paper 10 is saturated with water absorption.

[0027] Refer to Figure 1 and Figure 2 As shown, five cutting seams 11 are formed on the polymer fiber layer 1 of the splint body; an antibacterial film 12 is clamped inside the polymer fiber layer 1 of the splint body, and the antibacterial film 12 is located on the side of the water storage bag 3 away from the polyurethane layer 2 of the splint body.

[0028] By cutting along the cutting seams 11, the height of the polymer fiber layer 1 of the splint body and the polyurethane layer 2 of the splint body can be shortened to meet different length requirements, and cutting along the cutting seams 11 will not cut the water storage bag 3; the antibacterial film 12 can resist bacteria, prevent bacteria from entering and contacting the patient's fracture site, so as to protect the injured area.

[0029] The technical principles of the embodiments of the present utility model have been described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model and cannot be construed in any way as a limitation on the protection scope of the embodiments of the present utility model. Based on the explanations herein, those skilled in the art can readily conceive of other specific implementation manners of the embodiments of the present utility model without creative efforts, and these manners will fall within the protection scope of the embodiments of the present utility model.
