Technical Field

[0001] The utility model relates to the technical field of supporting auxiliary frames, in particular to a supporting auxiliary frame with an extended structure. Background Art

[0002] Patients with severe arm burns need to have their wounds reshaped during treatment to reduce scars on the skin after the burn. The skin after burn reshaping needs to be applied with ointment during follow-up care. In order to facilitate the application of the ointment, the patient's arm needs to be fixed with a support auxiliary frame to facilitate dressing changes on the arm.

[0003] After plastic surgery on a patient with severe arm burns, the patient's arm needs to be propped up and fixed by a support auxiliary frame, and then medicine is applied. The length of the bracket on the existing support auxiliary frame is generally fixed, and in order to prevent the wound on the patient's arm from being blocked, the bracket length is generally set shorter. However, the contact surface between the shorter bracket and the patient is also smaller, and the pressure is greater, which affects the comfort of the support auxiliary frame when used, and affects the patient's use when the wound on the patient's arm is small.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5The utility model provides a technical solution: a supporting auxiliary frame with an extension structure, comprising: a fixed frame 1 and an extension frame 13, the top of the fixed frame 1 is movably connected with a threaded rod 2 through a damping shaft, the top of the threaded rod 2 is fixedly connected with a fixed plate 3, one side of the fixed plate 3 is welded and fixed with a limiting rod 4, the outer side of the limiting rod 4 is slidably connected with a sliding plate 5, the top of the sliding plate 5 is movably connected with a supporting frame 6 through a damping shaft, and the top of the supporting frame 6 is welded and fixed with a bracket 7,

[0025] The inside of the bracket 7 is movably connected with a worm 8 through a bearing, and the outer side of the worm 8 is meshed with a worm wheel 9. The inside of the worm wheel 9 is fixedly connected with a first gear 10 through a connecting shaft, and the outer side of the first gear 10 is meshed with a second gear 15, and the second gear 15 and the outer sides of the first gear 10 are fixedly connected with a connecting plate 11; a lever 12 is welded and fixed to one side of the connecting plate 11, and an extension frame 13 is slidably connected to one side of the lever 12; a sliding groove 14 matching the lever 12 is provided on one side of the extension frame 13, and a sliding groove for sliding the bottom slider of the extension frame 13 is provided inside the bracket 7; one side of the second gear 15 is movably connected to the bracket 7 through a rotating shaft, and one side of the bracket 7 is provided with an arc groove for sliding the lever 12, the extension frame 13 forms a sliding structure with the bracket 7 through the slider, and the first gear 10 and the second gear 15 form a meshing transmission structure.

[0026] In specific implementation, after plastic surgery on a patient with severe arm burns, the patient's arm needs to be propped up and fixed by a support auxiliary frame, and then medicine is applied. When fixing the patient's arm, in order to improve the patient's comfort, the worm 8 is rotated to mesh with the worm wheel 9, and the worm wheel 9 can drive the first gear 10 to mesh with the second gear 15, so that the second gear 15 is reversed, and the second gear 15 and the first gear 10 will respectively drive a group of connecting plates 11 to rotate, and the connecting plates 11 will move in the slide groove 14 on one side of the extension frame 13 through the lever 12 on one side, pushing the two groups of extension frames 13 to extend to both sides, and the slider at the bottom of the extension frame 13 will limit it;

[0027] After the adjustment is completed, the worm screw 8 can be loosened, and the worm wheel 9 will not rotate at this time, and the position of the extension frame 13 will also be fixed. The extended extension frame 13 can distribute the pressure to different positions of the patient's arm and improve the support stability of the patient's arm. When the wound on the patient's arm is large, the two groups of extension frames 13 are driven closer to each other by reversing the worm screw 8. At this time, the overall length of the support auxiliary frame will be shortened to prevent obstruction to the wound on the patient's arm. In this way, the above operation can facilitate the extension of the bracket 7 of the support auxiliary frame, thereby improving the comfort and stability of the patient's use.

[0028] See also Figure 1 , Figure 2 and Figure 6The outer side of the threaded rod 2 is threadedly connected with a threaded sleeve 16, and a limiting block 17 is welded and fixed on the top of the threaded sleeve 16. The top of the limiting block 17 is connected with a sliding sleeve 18 through a ball rolling; an annular groove for the limiting block 17 to rotate is provided inside the sliding sleeve 18, and a connecting rod 19 is movably connected to one side of the sliding sleeve 18 through a rotating shaft; one side of the connecting rod 19 is movably connected to the sliding plate 5 through a rotating shaft, and a through groove for the threaded rod 2 to slide is provided inside the sliding sleeve 18, and the connecting rod 19 forms a rotating structure with the sliding plate 5 through the rotating shaft, and the sliding plate 5 and the limiting rod 4 form a sliding structure.

[0029] In specific implementation, after plastic surgery on a patient with severe arm burns, the patient's arm needs to be propped up and fixed by the support auxiliary frame, and then medicine is applied. In order to make the support auxiliary frame adapt to the patient's body shape and position, the threaded sleeve 16 and the threaded rod 2 are threadedly transmitted by rotating the threaded sleeve 16. When the threaded sleeve 16 rotates, it will slide in the annular groove at the bottom of the sliding sleeve 18 through the limit block 17. When the threaded sleeve 16 moves, it will push the sliding sleeve 18 to move upward. As the sliding sleeve 18 moves, the connecting rod 19 on one side of it will also rotate and unfold, thereby pushing the sliding plate 5 to move. The limiting rod 4 inside the sliding plate 5 can guide and limit the sliding plate 5 and support it at the same time. The sliding plate 5 can change the position of the movable bracket 7, so that the use size of the support auxiliary frame changes to adapt to patients with different body shapes and positions. The unfolded connecting rod 19 can also support the sliding plate 5. In this way, the size of the support auxiliary frame can be easily adjusted through the above operation, which is convenient for use in various scenarios.

[0030] To sum up: when using the support auxiliary frame with an extendable structure, first fix the support auxiliary frame to the bed frame through the bolts at the bottom of the fixing frame 1, and then put the patient's arm on the bracket 7. By rotating the threaded rod 2 and the support frame 6, the position of the bracket 7 can be changed to facilitate the medication work.
