[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] One embodiment of this utility model provides: a protective device for raising the upper limbs, such as... Figure 1 As shown, it includes a base 1, a support mechanism 2, a comfort layer 3, and an angle adjustment component 4.

[0024] like Figure 1 and Figure 2 As shown, the support mechanism 2 includes a horizontal support assembly 21 and an inclined support assembly 22. The inclined support assembly 22 includes an upper arm support 221, a telescopic adjustment member 222, an elbow joint support 223, and a forearm and wrist support 224.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a base 1 is provided below the horizontal support assembly 21 and the inclined support assembly 22. The horizontal support assembly 21 is fixedly connected to the base 1. The side of the upper arm support 221 of the inclined support assembly 22 away from the telescopic adjustment component 222 is hinged to the horizontal support assembly 21. An angle adjustment component 4, which can change the angle between the horizontal support assembly 21 and the base 1, is installed between the inclined support assembly 22 and the base 1. When not in use, the inclined support assembly 22 can be kept parallel to the horizontal support assembly 22, with the inclined support assembly 22 resting in the base 1. When the patient needs to use the device, the angle of the inclined support assembly 22 is adjusted so that the upper surface of the inclined support assembly 22 is inclined to the horizontal support assembly 21. In the case of upper limb injury, the patient's arm can be raised under the support of the device, which is more conducive to recovery. At the same time, the degree of arm raising can be achieved by changing the angle between the inclined support assembly 22 and the base 1, so that the degree of raising can be set according to the specific situation of the patient. The inclined support assembly 22 can be adjusted to fall back into the base 1, which reduces the size of the device when it is not in use, saves space, and makes it easy to store.

[0026] like Figure 4 and Figure 5 As shown, the angle adjustment assembly 4 includes a fixed base 41, a support rod 42, a roller 43, and a fixed connector 44. One end of the support rod 42 is hinged to the fixed base 41, and the other end is hinged to the roller 43. The fixed base 41 is fixedly connected to the side of the elbow joint support 223 of the inclined support assembly 22. The roller 43 is located in the groove 11 of the upright plate of the base 1 and is slidably connected to the upright plate of the base 1. When the angle between the horizontal support assembly 21 and the base 1 is fixed, the roller 43 is relatively fixed to the base 1 through the fixed connector 44. The screw 441 of the fixed connector 44 is threadedly connected to the slot 431 of the roller 43. When the fixed connector 44 is tightened, the roller 43 is tightly against the inner side of the slot 431, and the fixed connector 44 is tightly against the outer side of the slot 431.

[0027] When adjusting the angle of the inclined support assembly 22 of the device, the fixed connector 44 on the horizontally moving roller 43 moves in the slide groove 11, and the angle of the inclined support assembly 22 changes accordingly. When the inclined support assembly 22 rotates to a suitable tilt angle, the fixed connector 44 is tightened, the distance between the fixed connector 44 and the roller 43 decreases, and the base 1 upright plate is clamped, thus fixing the roller 43 to the base 1. When the roller 43 is stationary, the support rod 42 can support the inclined support assembly 22 to maintain the angle.

[0028] A first anti-slip pad 432 is provided on the side of the roller 43 near the fixed connector 44, and a second anti-slip pad 442 is provided on the side of the fixed connector 44 near the roller 43. When tightened, both the roller 43 and the fixed connector 44 are pressed against the upright plate of the base 1. The action of the first and second anti-slip pads 432 increases the friction between the roller 43, the fixed connector 44, and the upright plate of the base 1, making the support for the patient's upper limb more stable after the device's angle is adjusted.

[0029] The angle adjustment component 4 and the slide 11 are symmetrically arranged on both sides of the inclined support component 22 to increase the stability of the inclined support component 22 after angle adjustment.

[0030] like Figure 2 and Figure 6 As shown, the upper arm support 221 is connected to the horizontal support assembly 21, the elbow joint support 223 is connected to the upper arm support 221 via a telescopic adjustment member 222, and the forearm and wrist support 224 is connected to the elbow joint support 223 via the telescopic adjustment member 222. The horizontal support assembly 21 supports the patient's shoulder. Based on the length of the patient's upper limb and the corresponding matching of the effective support positions, the distance between each support part can be adjusted, thereby improving the patient's comfort when the device is raised and increasing the device's support effect.

[0031] The telescopic adjustment component 222 includes a fixed end 2221, a movable end 2222, and a limiting component 2223. One end of the movable end 2222 passes through the interior of the fixed end 2221, and the movable end 2222 and the fixed end 2221 are slidably connected. The limiting component 2223 is provided at the overlapping part of the fixed end 2221 and the movable end 2222. The limiting component 2223 can adjust the fixed end 2221 and the movable end 2222 to be in two states: relative sliding and relative fixed. The limiting component 2223 includes a connecting seat 22231 and a knob 22232. The connecting seat 22231 is installed at the end of the fixed end 2221 near the movable end 2222, and the knob 22232 is threadedly connected to the connecting seat 22231.

[0032] When adjusting the distance between the elbow joint support 223 and the upper arm support 221, and between the forearm and wrist support 224 and the elbow joint support 223, the adjustment is achieved by adjusting the telescopic adjustment component 222 between them. During adjustment, after loosening the knob 22232 relative to the connecting seat 22231, the fixed end 2221 and the movable end 2222 can slide relative to each other, changing the length of the movable end 2222 inserted into the fixed end 2221. This ensures that the distance between the elbow joint support 223 and the upper arm support 221, or between the forearm and wrist support 224 and the elbow joint support 223, matches the specific length of the patient's upper arm and forearm. Tightening the knob 22232 again fixes the fixed end 2221 and the movable end 2222 relative to each other, completing the adjustment of the support part to correspond with the patient's upper limb condition.

[0033] like Figure 2 and Figure 3 As shown, a comfort layer 3 is provided on the surface of the support mechanism 2. The comfort layer 3 includes a horizontal support sponge pad 31, an upper arm support sponge pad 32, an elbow joint support sponge pad 33, and a forearm and wrist support sponge pad 34. The horizontal support sponge pad 31 is positioned above the horizontal support assembly 21, the upper arm support sponge pad 32 is positioned above the upper arm support 221, the elbow joint support sponge pad 33 is positioned above the elbow joint support 223, and the forearm and wrist support sponge pad 34 is positioned above the forearm and wrist support 224. The comfort layer 3 is located between the patient's skin and the support mechanism 2. The flexible material of the comfort layer 3 provides comfort when the patient's upper limb is elevated, protecting the injured upper limb.

[0034] The elbow joint support 223 has a first through hole 2231 extending downwards from the middle. The elbow joint support sponge pad 33 has a second through hole 331 corresponding to the first through hole 2231 of the elbow joint support 223. When adjusting the various support parts of the support mechanism 2, the first through hole 2231 of the elbow joint support 223 should be aligned with the patient's elbow joint. The placement of the second through hole 331 and the first through hole 2231 provides space for the patient's elbow joint. This device is particularly suitable for patients with ulnar nerve damage. While elevating the upper limb, it also avoids compression of the ulnar nerve, which is beneficial for recovery and helps patients recover as quickly as possible.
