[0026] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0027] according to Figure 1 - Figure 8 As shown, this embodiment provides a support device for bone injury, including a base 1, a rotating assembly, a lifting assembly and a placement tray 2. The upper end of the base 1 is provided with a rotating assembly for the lifting assembly to rotate, and a placement tray 2 for the patient's foot to be placed is provided on one side of the lifting assembly. The rotating assembly includes a sleeve 6, a rotating seat 7, a ball 8 and a first bearing 9. The sleeve 6 is fixedly installed on the upper end of the base 1, and a horizontally rotatable rotating seat 7 is provided inside the sleeve 6. A slide groove for installing the ball 8 is provided between the bottom of the rotating seat 7 and the inner bottom end of the sleeve 6, and the outer wall of the rotating seat 7 and the inner wall of the sleeve 6 are installed through the first bearing 9. The use orientation of the placement tray 2 is adjusted by setting the rotating assembly, so that the use position of the placement tray 2 can be adjusted to a more comfortable use orientation for the patient's ankle.

[0028] The middle part of the base 1 is provided with a fixed area for docking the stretcher rod, a fixed clamping block 3 is fixedly installed at the upper end of the fixed area, and a movable clamping block 4 that can move longitudinally is provided below the fixed clamping block 3;

[0029] A placement groove is provided in the middle of the placement tray 2, and a U-shaped airbag cushion 5 for positioning the patient's ankle is provided in the middle of the placement groove. Considering that the existing stretcher does not have a supporting device for lifting the patient's ankle, when the patient with a sprained foot is transferred using a stretcher, when the ankle is not lifted, it will cause aggravated swelling. When in use, the movable clamp block 4 and the fixed clamp block 3 are used to cooperate with each other to fix the device on the armrest of the stretcher, and then the use direction of the placement tray 2 is adjusted by the adjustment component. After the adjustment is completed, the patient places the foot on the placement tray. The foot of the patient is placed in the placement groove in the middle of the support 2, and then the adjustment slider 15 is moved on the T-shaped slide rail 14 to lift the patient's foot, thereby promoting blood circulation at the distal end of the foot. At the same time, in order to ensure that the patient's ankle is no longer injured again during the transfer process, the inflated telescopic airbag 19 is used to drive the two ends of the horizontally placed U-shaped airbag cushion 5 to be squeezed toward the middle, thereby completing the micro-fixation of the patient's ankle. At the same time, the gas in the U-shaped airbag cushion 5 may not be filled, so that it can fit the shape of the patient's ankle without causing excessive squeezing.

[0030] Considering the problem that the rotation angle needs to be fixed after the rotating seat 7 rotates, a spring latch 10 is fixedly installed on the side wall of the sleeve 6, and a reserved hole for the spring latch 10 to pass through is opened in the middle of the sleeve 6, and the pin head of the spring latch 10 is fixedly installed with a block 12 adapted to the teeth of the positioning toothed ring 11. The positioning toothed ring 11 is fixedly installed on the upper end of the outer side of the rotating seat 7, and the outer size of the teeth of the positioning toothed ring 11 matches the size of the groove inside the block 12. The teeth on the positioning toothed ring 11 are engaged to fix the rotating seat 7 after rotation. When adjusting, the spring latch 10 will be pulled. At this time, the block 12 of the pin head of the spring latch 10 will be away from the teeth of the positioning toothed ring 11, so that the rotation of the rotating seat 7 inside the sleeve 6 can be completed. After the rotation adjustment is completed, the spring latch 10 will be released. At this time, the spring structure of the spring latch 10 itself will be used to complete the resetting process, so that the block 12 will re-engage the teeth of the positioning toothed ring 11 to complete the fixing process.

[0031] Taking into account that when a patient sprains his ankle, the ankle can be raised to assist blood circulation at the distal end of the foot, thereby improving swelling, the lifting assembly includes a column 13, a T-shaped slide rail 14, a slider 15 and a positioning bolt 16. A T-shaped slide rail 14 for longitudinal movement of the slider 15 is fixedly installed on one side of the column 13, and a clearance groove matched with the external size of the T-shaped slide rail 14 is provided on the contact surface between the slider 15 and the T-shaped slide rail 14, and the positioning bolt 16 is threadedly connected to the lower end of the side wall of the slider 15. The slider 15 is displaced on the T-shaped slide rail 14 to increase the use height of the placement tray 2. After adjusting to the specified position, the positioning bolt 16 is tightened to complete the fixation between the slider 15 and the T-shaped slide rail 14.

[0032] The bottom of the column 13 is fixedly connected to the upper end of the rotating seat 7 , and the rotating seat 7 is provided to enable the column 13 to rotate in the horizontal direction.

[0033] Taking into account that the medical staff will be bumped during the process of transferring the patient using a stretcher, in order to prevent the patient's foot from falling off the placement tray 2 in this case, the side wall of the placement tray 2 is fixedly connected to the side wall of the slider 15, and Velcro hook surfaces 17 are fixed on both sides of the middle of the placement groove, and the placement groove is installed with the Velcro fur surface 18 of the side wall of the telescopic airbag 19 through the Velcro hook surface 17, and the telescopic airbag 19 is fixedly connected to the U-shaped airbag cushion 5, and a reserved cavity for gas is opened in the middle of the U-shaped airbag cushion 5, and the inflated telescopic airbag 19 will be used to make the two ends of the U-shaped airbag cushion 5 move closer to the middle, so as to position the patient's ankle and prevent it from falling off. At the same time, considering that the patient's ankle cannot be excessively squeezed to avoid affecting the sprain position, the U-shaped airbag cushion 5 that is not filled with gas will be used to compensate the patient.

[0034] The cross-section of the telescopic airbag 19 is designed as a U-shaped structure, and the telescopic airbag 19 is wrapped around the outside of the U-shaped airbag. The front end of the telescopic airbag 19 is connected to an injection valve 20, and the interior of the telescopic airbag 19 is sealed by setting the injection valve 20.

[0035] The upper end of the injection valve 20 is connected to a telescopic tube 21, and one end of the telescopic tube 21 is connected to the injection end of the inflated balloon 22. The inflated balloon 22 is fixed to the other side wall of the column 13 by a metal spring 23. The metal spring 23 is provided to place the inflated balloon 22. At the same time, the existence of the telescopic tube 21 will facilitate medical staff to remove the inflated balloon 22 and press it for use.

[0036] A guide rail 24 for the longitudinal movement of the movable clamping block 4 is provided on the side of the fixed area, and a groove body adapted to the guide rail 24 is provided on one side of the movable clamping block 4. The middle part of the bottom end of the base 1 is threadedly connected with a limit bolt 25, and the top of the limit bolt 25 is rotatably connected to the middle part of the bottom end of the movable clamping block 4 through a second bearing. The limit bolt 25 is provided to drive the movable clamping block 4, and the screwing in or loosening of the limit bolt 25 drives the movable clamping block 4 to move longitudinally.

[0037] Considering that the friction between the contact surfaces of the movable clamp block 4 and the fixed clamp block 3 and the handrail will be enhanced by the rubber pad 26, the contact surfaces of the movable clamp block 4 and the fixed clamp block 3 and the stretcher handrail are fixed with rubber pads 26.
