Description

Technical Field

[0001] This utility model relates to the field of rehabilitation assistive devices, specifically an upper arm lifting device. Background Technology

[0002] For patients with shoulder bone, muscle, or nerve damage, the entire upper arm hangs limply under gravity, unable to be raised, extended forward, or swing outward. Although their forearm and hand functions are intact, the lack of traction and drive from the upper arm renders them unable to perform even simple actions like eating and drinking, severely impacting their daily lives. Current solutions involve using a bandage to tightly wrap the upper arm, with a tension strap on the bandage pulling the affected limb upwards at an angle. The other end of the tension strap is fixed to the opposite shoulder, providing some stabilization. However, because the tension is directed upwards, the force used to lift the upper arm is only a component of the bandage's overall force. Furthermore, due to the human body's structure, the angle between this component and the bandage's force is large, resulting in a small overall force that primarily serves a stabilizing function with limited lifting effect.

[0020] 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.

[0021] As attached Figure 1-7 As shown, the upper arm lifting device involved in this utility model includes a fixing unit 1, a fixing lifting unit 2, and an upper arm extension and abduction unit 3.

[0022] As attached Figure 1 , 2 As shown, the fixation unit 1 is used to securely and firmly place the fixation lifting unit 2 and the upper pre-extension abduction unit 3 onto the patient. The fixation unit 1 includes a fixation plate 1-1 and a fixation strap 1-2. The fixation strap 1-2 secures the fixation plate 1-1 onto the patient. (See attached diagram.) Figure 1 , 2 As shown in Figure 3, the fixing plate 1-1 is installed on the back of the body, and the back plate is made of rigid but elastic plastic or metal. The fixing strap 1-2 includes shoulder strap 1-2-1 and chest strap 1-2-2, which achieve stable placement of the fixing plate 1-1.

[0023] Specifically, the upper end of shoulder strap 1-2-1 is connected to both sides of the upper part of fixing plate 1-1, and one end of chest strap 1-2-2 is connected to both sides of the lower part of fixing plate 1-1. The lower end of shoulder strap 1-2-1 and chest strap 1-2-2 are adjustablely connected via connecting buckle 1-3. Chest strap 1-2-2 includes a central strap d1 and two side straps d2. One end of side strap d2 is connected to the lower part of fixing plate 1-1, and the other end of side strap d2, the lower end of shoulder strap 1-2-1, and one or both sides of the central strap d1 are Velcro fasteners. These fasteners pass through connecting buckle 1-3 and are adjustable via Velcro fasteners. Connecting buckle 1-3 includes two vertical slots and one horizontal slot for inserting the side straps, central strap, and shoulder strap.

[0024] The fixing straps 1-2 can also be other structures, such as having only one shoulder strap.

[0025] As attached Figure 1 , 3 As shown, the fixed lifting unit 2 includes an arm wrapping tube 2-1 and a lifting strap 2-2.

[0026] The arm wrap tube 2-1 is wrapped around the lower end of the upper arm and secured with Velcro to ensure a tight wrap. Furthermore, an air bladder can be installed in the arm wrap tube 2-1, and the wrapping force can be adjusted by inflating the air bladder through an inflation device.

[0027] Several lifting straps 2-2 are provided on the arm wrapping tube 2-1. In the attached diagram, there are two lifting straps 2-2, namely the front lifting strap 2-2-1 and the side lifting strap 2-2-2.

[0028] The lower ends of the front pull strap 2-2-1 and the side pull strap 2-2-2 are fixedly or detachably connected to the arm wrapping tube 2-1. To ensure the relative position of the front pull strap 2-2-1 and the side pull strap 2-2-2 after wrapping the arm wrapping tube 2-1, both the front pull strap 2-2-1 and the side pull strap 2-2-2 can be detachably connected, or only one of them can be detachably connected. The lower ends of the front pull strap 2-2-1 and the side pull strap 2-2-2 can be detachably connected with adjustable positions using Velcro, buttons, or other structures. The attached diagram shows a Velcro structure. The outer side of the arm wrapping tube 2-1, except for the ends, has a rough surface to facilitate the connection of the lower ends of the front pull strap 2-2-1 and the side pull strap 2-2-2.

[0029] The two lifting straps are positioned one directly in front of the upper arm and the other on the outside of the upper arm, with their vertical center planes perpendicular to each other. This ensures that when the upper arm is extended forward, the force applied to the lifting strap directly in front of the upper arm is effective, maximizing force application efficiency. The lifting straps are designed to be flexible, allowing users to continuously adjust the tension and determine the final tension based on their own comfort to achieve the most comfortable shoulder position.

[0030] As attached Figure 4 ,5 As shown in Figure 6, the upper extension and abduction unit 3 includes a connector 3-1, an adjuster 3-2, and an adjustable connecting assembly 3-3. One end of the connector 3-1 is fixed to the fixing plate 1-1, and the other end extends to the side of the upper arm of the affected limb. The adjuster 3-2 is connected to the connector 3-1 through the adjustable connecting assembly 3-3, allowing adjustment of the relative position of the adjuster 3-2 and the connector 3-1. Specifically, the adjuster 3-2 can rotate relative to the connection position.

[0031] The adjusting component 3-2 is provided with a front connecting buckle t1 and a side connecting buckle t2. The front connecting buckle t1 and the side connecting buckle t2 are located in front and to the side of the upper part of the affected limb's upper arm. The upper ends of the front pull strap 2-2-1 and the side lifting strap 2-2-2 are adjustablely connected to the front connecting buckle t1 and the side connecting buckle t2. Specifically, after the upper ends of the front pull strap 2-2-1 and the side lifting strap 2-2-2 are inserted into the slots on the front connecting buckle t1 and the side connecting buckle t2, the ends are reversed 180° and attached to the lifting strap with Velcro.

[0032] Furthermore, the side connecting buckle t2 is detachably fixed to the adjusting member 3-2, as shown in the attached figure. Figure 4-6 As shown, a slot is provided on the adjusting component 3-2, and the side connecting buckle t2 is inserted into the slot. A threaded hole is provided at the bottom of the slot. The side connecting buckle t2 is detachably connected to the adjusting component 3-2 through the adjusting bolt t21.

[0034] Adjustable connection assembly 3-3 includes a housing j1, a central tooth j2, a locking bolt j3, and a compression spring j4. The housing j1 is fixed to the connector 3-1 by screws. Specifically, the central tooth j2 includes a central cap j21, which is cylindrical in shape. An end face is provided on the side away from the affected limb. A locking threaded hole j211 is provided in the center of the end face, and an adjusting post insertion groove j212 is provided on the end. On the side opposite to the adjusting post insertion groove j212, a protrusion j213 is provided on the side of the central cap j21, and a meshing tooth j214 is provided on the lower outer side of the protrusion j213.

[0035] The outer shell j1 is generally hat-shaped, including a central cylinder j11 and a fixed protruding edge j12. A partition is provided in the middle of the central cylinder j11, and a through hole j111 is provided in the center of the partition. The top of the central cap j21 can pass through the through hole j111. The central cap j21 is slidably engaged with the through hole j111, that is, the central cap j21 can slide back and forth in the through hole j111 in the axial direction.

[0036] A meshing tooth groove j112 is provided on the inner side of the partition plate of the central cylinder j11, which cooperates with the meshing tooth j214.

[0037] The adjusting component 3-2 is provided with a connecting cylinder t3. The inner diameter of the connecting cylinder t3 is slightly larger than the outer diameter of the central cylinder j11 of the outer shell j1. The central cylinder j11 is inserted into the connecting cylinder t3; or the outer diameter of the connecting cylinder t3 is equal to the outer diameter of the central cylinder j11 of the outer shell j1. When the screw J3 is fully tightened, the end face of the central cylinder and the end face of the connecting cylinder t3 are in contact. The locking bolt j3 and the adjusting column t31 keep the adjusting component 3-2 and the outer shell j1 concentrically connected.

[0038] An adjusting column t31 is provided on the top surface of the inner wall of the connecting cylinder t3, and the adjusting column t31 is inserted into the adjusting column insertion slot j212. The central tooth j2 can be moved by adjusting column t31.

[0039] A through hole or threaded hole is provided on the top surface of the connecting cylinder t3. The locking bolt j3 is inserted into the through hole or threaded hole on the top surface of the connecting cylinder t3 and engages with the locking threaded hole j211 in the center of the central cap j21.

[0040] The compression spring j4 is located between the partition plate of the central cap j2 and the top surface of the inner wall of the connecting cylinder t3, and between the outer side of the central tooth j2 and the inner wall of the central cylinder j11.

[0041] When using: After the fixing plate 1-1 of the fixing unit 1 is securely placed by the fixing strap 1-2, wrap the arm wrapping tube 2-1 around the lower end of the upper arm and secure it with Velcro to ensure that the upper arm is tightly wrapped. Adjust the position of the front pull strap 2-2-1 and the side pull strap 2-2-2 so that they are in front of and to the side of the upper arm.

[0042] Afterwards, loosen the adjusting bolt t21, adjust the front and rear positions of the side connecting buckle t2 in the slot of the adjusting part 3-2, and after adjusting the position, the angle of the upper arm extension is determined. Then tighten the adjusting bolt t21.

[0043] Loosen the locking bolt j3 partially and rotate the adjusting piece 3-2 counterclockwise to adjust it to the appropriate angle. Specifically, during the adjustment process, press the adjusting piece 3-2 inward, compress the spring j4, and disengage the meshing tooth j214 from the meshing groove j112. Then, rotate the adjusting piece 3-2 to loosen it. The spring j4 pushes the adjusting piece 3-2 outward, and the adjusting piece 3-2, through the locking bolt j3, pulls the central tooth j2, causing the meshing tooth j214 to engage with the meshing groove j112, preventing the adjusting piece 3-2 from slipping. This allows for convenient adjustment of the relative angle of the adjusting piece 3-2, enabling one-handed adjustment. After adjusting to the appropriate angle, tighten the locking bolt j3 to completely secure the meshing tooth j214 to the meshing groove j112, thus fixing the relative positions of the adjusting piece 3-2 and the connecting piece 3-1.

[0044] Then connect the upper part of the front pull strap 2-2-1 and the side pull strap 2-2-2 to the front connecting buckle t1 and the side connecting buckle t2, and adjust them with Velcro to make them tight, thereby achieving the lifting of the upper arm and the forward extension and abduction of the upper arm.

[0045] When you want to lower your arm, loosen the Velcro straps of the front pull strap 2-2-1 and the side pull strap 2-2-2. In operation, you can first slowly loosen the side pull strap 2-2-2, and then slowly loosen the front pull strap 2-2-1, and gradually lower your arm.

[0046] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
