DETAILED DESCRIPTION

[0024] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0025] Example: A pediatric orthopedic fixation splint, see Figure 1-Figure 3 , comprising three arc-shaped fixing plates 1, the inner wall of the arc-shaped fixing plate 1 is made of silicone material, a plurality of ventilation holes 5 are evenly opened on the arc-shaped fixing plate 1, a fixing belt 2 and a fixing buckle 21 are respectively fixed to the left and right ends of the arc-shaped fixing plate 1, the fixing belt 2 passes through the fixing buckle 21, a Velcro mother surface 3 and a Velcro sub-surface 4 are fixed to the fixing belt 2, the Velcro mother surface 3 and the Velcro sub-surface 4 are both located on the upper end surface of the fixing belt 2, the Velcro mother surface 3 and the Velcro sub-surface 4 are respectively located on both sides of the fixing buckle 21, and a T-shaped guide rail 7 and a T-shaped slide groove 8 adapted to the T-shaped guide rail 7 are respectively provided at the front and rear ends of the arc-shaped fixing plate 1.

[0026] When in use, the staff determines the number of arc-shaped fixing plates 1 to be used according to the range of the injured part of the child, slides the T-shaped guide rail 7 of one arc-shaped fixing plate 1 into the T-shaped slide groove 8 of another arc-shaped fixing plate 1, thereby connecting and assembling into a fixing splint. Then, the staff drags the fixing splint to the injured part of the child, wraps the fixing belt 2 around the injured limb, passes through the fixing buckle 21, and bonds the Velcro sub-surface 4 with the Velcro mother surface 3 together, thereby fixing the position of the injured limb on the arc-shaped fixing plate 1. When the length of the fixing splint needs to be increased, it is only necessary to add an arc-shaped fixing plate 1 by connecting the T-shaped guide rail 7 with the T-shaped slide groove 8, and then bond and fix the fixing belt 2, thereby facilitating the change of the length of the fixing splint to effectively protect the injured limb.

[0027] See also Figure 4 and Figure 5 A guide plate 9 is fixedly connected to the left and right ends of the arc-shaped fixed plate 1, a positive limit plate 10 is slidably penetrated on the right end guide plate 9, a negative limit plate 11 is slidably penetrated on the left end guide plate 9, a positive magnet 12 is arranged at the left end of the T-shaped guide rail 7, a negative magnet 13 is arranged at the right end of the T-shaped guide rail 7, the positive magnet 12 and the negative magnet 13 are positive and negative poles used in combination, and the positive limit plate 10 and the negative limit plate 11 are respectively provided with the positive magnet 12 and the negative magnet 13.

[0028] See also Figure 4 and Figure 5, and also includes a return spring 14, two return springs 14 are provided, one return spring 14 is connected between the positive limit plate 10 and the guide plate 9, and the other return spring 14 is connected between the guide plate 9 and the negative limit plate 11.

[0029] When the T-shaped guide rail 7 is pushed into the T-shaped slot 8, the positive magnet 12 is close to the positive limit plate 10 or the negative magnet 13 is close to the negative limit plate 11, a repulsive force is generated due to the same magnetism, and the positive limit plate 10 or the negative limit plate 11 slides upward, and the reset spring 14 can limit the sliding range. When the T-shaped guide rail 7 and the T-shaped slot 8 are completely closed, the positive magnet 12 is close to the negative limit plate 11 and the negative magnet 13 is close to the positive limit plate 10. Due to the opposite magnetism, an adsorption force is generated, causing the positive limit plate 10 and the negative limit plate 11 to slide downward, thereby limiting and fixing the left and right ends of the T-shaped guide rail 7 to prevent the T-shaped guide rail 7 from sliding. When the fixed splint needs to be disassembled, the positive limit plate 10 and the negative limit plate 11 are pushed upward to push the T-shaped guide rail 7 out of the T-shaped slot 8, and the reset spring 14 is reset and supports the positive limit plate 10 and the negative limit plate 11.

The disinfection layer 16 is a multi-layer laminated structure and is made of absorbent cotton and straw fiber paper. A plurality of buffer pads 6 are fixed to the inner wall of the fixing belt 2. The buffer pads 6 are all made of polymer elastic material.

[0033] The disinfection layer 16 can play a disinfection role to prevent bacteria from growing inside the fixed splint. At the same time, due to its elastic material, it can play a buffering and shock-resistant effect; the buffer pad 6 can reduce the pressure and friction of the fixation belt 2 on the child's limbs; heat dissipation and ventilation are carried out through the vents 5 to keep the child's limbs comfortable.

[0034] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
