Description

Technical Field

[0001] This invention relates to rehabilitation equipment, and more specifically to a shoulder joint exerciser. Background Technology

[0002] The significance of shoulder rehabilitation exercises lies in helping to restore shoulder joint function and reduce pain, as shoulder injuries or surgeries often result in limited range of motion. Rehabilitation exercises aim to gradually increase the shoulder joint's range of motion, restoring flexibility through stretching and mobilization. This helps improve shoulder joint function, enabling the performance of various daily activities. Furthermore, targeted strength training in rehabilitation exercises can strengthen the muscles surrounding the shoulder. Strong muscles provide better support and stability, reducing the burden on the shoulder joint and lowering the risk of re-injury. Secondly, shoulder rehabilitation exercises include coordination training, which helps restore muscle coordination and balance. This is crucial for normal shoulder joint function, improving stability and the precision of movement.

[0003] Publication (Announcement) No.: CN111035897B, Publication (Announcement) Date: 2021-05-28, discloses a shoulder joint exercise device, including a support and a training board. The training board includes a board body, several concentric annular protrusions located on the front side of the board body with successively increasing radii, first support ears located on the left and right sides of the board body, and a slider slidably disposed in annular grooves between adjacent concentric annular protrusions. The concentric annular protrusions are provided with notches that connect adjacent annular grooves. The support column is provided with several elongated holes. The first support ears are fixed to the column by bolts and nuts, which can cooperate to perform a variety of different shoulder joint movements and help patients judge the training progress.

[0004] Publication (Announcement) No.: CN113750468B, Publication (Announcement) Date: 2022-12-02, discloses a post-arthroscopic shoulder exercise device. This post-arthroscopic shoulder exercise device includes: a cylindrical body; a rack; two gear assemblies; two grip components; and two rack adjustment components. When either of the two grip components tilts, it drives the corresponding gear assembly to rotate, causing the rack to slide accordingly, thus causing the other grip component to tilt synchronously. The sliding range of the rack is limited by the rack adjustment components to control the tilt range of the two grip components. In use, one hand or another person can guide the hand undergoing surgery to perform restorative rotation exercises. The sliding range of the rack can be adjusted through the rack adjustment components, thereby controlling the tilt range of the grip components, making the angle of arm rotation controllable. Based on this, the number of rotations can be combined to quantify the restorative exercise, preventing the sutured rotator cuff from tearing again due to improper exercise.

[0005] In the prior art, including the aforementioned patents, shoulder rehabilitation differs from that of the limbs. Shoulder rehabilitation requires treatment of lacerations, clavicle fractures, dislocations, etc. Therefore, during rehabilitation, shoulder movements cannot be too far. When raising the arm, the shoulder muscle group begins to work together, but when lowering it, due to muscle weakness or poor coordination, the arm will fall quickly, causing pain or secondary injury to the patient.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-5 As shown, a shoulder joint exerciser includes a shoulder brace 1 and an upper arm brace 2, and a hinged rod assembly is provided between the two to maintain their deflection.

[0036] The first rod 80, which is hinged to the back of the shoulder brace 1, is rotatably connected to the end of the second rod 81, which is hinged to the back of the upper arm brace 2.

[0037] An electric push rod is rotatably mounted on the first rod body 80. The output end of the electric push rod is hinged to the second rod body 81 and arranged near the upper arm guard part 2.

[0038] It also includes a worm gear 82, and worm wheels 83 are respectively provided on the shafts at the connection points of the first rod body 80 and the second rod body 81 with the shoulder support 1 and the upper arm guard part 2, and the worm gear 82 meshes with the worm wheel 83.

[0039] Specifically, in the above embodiments, the first flexible protective gear 11 and the second flexible protective gear 21 are respectively provided with a hanging loop 7 and a binding strap 71, and the binding strap 71 is provided with a hook and loop fastener 72 and a hook and loop fastener loop fastener 72. That is, the binding strap 71 is bound to the patient's shoulder and upper arm by passing through the hanging loop 7 and folding it over so that the hook and loop fastener loop fastener and the hook and loop fastener 72 are pinched together.

[0040] In this embodiment, there are two worm gears 82, which are respectively installed on the adapters on the back of the shoulder brace 1 and the upper arm brace 2, while the worm wheels 83 on the shafts of the first rod body 80 and the second rod body 81 mesh with the worm gears 82 respectively.

[0041] In the above technology, the shoulder support 1 is worn on the shoulder, while the upper arm protector 2 is worn on the upper arm. The length of the hinged rod assembly is adjusted to suit the actual wearing needs. The electric push rod retracts, thereby driving the upper arm protector 2 upward to perform an arm-raising action. Then, during the extension and retraction, an arm-lowering action is performed. During this process, as the first rod 80 and the second rod 81 rotate, the worm gear 83 drives the worm 82 to rotate, thereby providing a large damping force to increase the speed of the arm-lowering and arm-raising actions. Alternatively, the electric push rod retracts, thereby driving the upper arm protector 2 upward to perform an arm-raising action. Then, the arm actively exerts force to perform an arm-lowering action. The worm gear 83 drives the worm 82 to rotate, thereby providing a large damping force, providing speed and safety for the arm-lowering action.

[0042] In a further embodiment of the present invention, a protein sponge soft liner 9 is provided inside the shoulder support 1, and a storage bag containing a predetermined liquid is provided inside the protein sponge soft liner 9, and a heater is provided inside the storage bag.

[0043] Specifically, the shoulder support 1 in this embodiment is equipped with a battery, a control panel, and a USB interface for connecting an external charger. In the above technology, the control panel controls the battery to supply power to the heater, and stops supplying power to the heater when the temperature sensor inside the storage bag detects that the temperature has reached 45°C.

[0044] The aforementioned electronic components and control programs are all common technical knowledge known to those skilled in the art, and therefore will not be described in detail.

[0045] In another embodiment of the present invention, the articulated rod assembly includes a third rod 3 and a fourth rod 4; a first flexible protective device 11 is provided on the port of the shoulder support 1, and a second flexible protective device 21 is provided on the port of the upper arm protective device 2; the first flexible protective device 11 has a boring hole for the fourth rod 4 to slide in, and the articulated rod assembly slides into the boring hole; the third rod 3 is provided with an elastic tenon 6, which is engaged in the tenon groove 13 provided in the first flexible protective device 11.

[0046] Specifically, in the above embodiment, the hinge rod assembly can be disengaged from the boring hole by pulling, changing the distance between the shoulder brace 1 and the upper arm brace 2, thereby adapting to the use of people of different ages. Secondly, the first flexible brace 11 and the second flexible brace 21 are made of flexible material, and silicone air cushion blocks 5 are fixedly installed on the outer walls of adjacent sides of the first flexible brace 11 and the second flexible brace 21. It also includes an air pump and a pressure sensor. The pressure sensor is used to detect the pressure on the silicone air cushion block 5, and the pressure sensor is controlled by the air pump. When the device is started, the air pump inflates the silicone air cushion block 5, compressing the patient's shoulder and muscles. After the pressure sensor detects the predetermined pressure, the inflation stops, and the pressure is memorized. Then, as the patient performs arm raising and lowering exercises, the air is deflated and inflated at the rated pressure to massage the muscles.

[0047] The aforementioned electronic components and control programs are all common technical knowledge known to those skilled in the art, and therefore will not be described in detail.

[0048] As a final embodiment further provided by the present invention, a groove 14 is provided on one side of the boring hole, and the anti-detachment protrusion 41 provided at the end of the fourth rod 4 slides within the groove 14.

[0049] Furthermore, the third rod body 3 is provided with a movable groove 31, and the elastic tenon 6 includes a connecting part and a pushing part. The connecting part is connected to the inner wall of the movable groove 31, while the pushing part can be engaged with the tenon groove 13. The end of the tenon groove 13 is slidably provided with a pressure rod 12, and the pushing part and the pressure rod 12 move synchronously.

[0050] Specifically, during the movement of the fourth rod 4, the third rod 3 enters the boring hole. At this time, as the pushing part slides along the boring hole, the connecting part is in an inclined deformed state. When it reaches the tenon 13 position, the pushing part is tenoned into the tenon 13 and then pushes the pressure rod 12 upwards to a higher position. When release is needed, simply press the pressure rod 12 and pull out the third rod 3; the operation is simple and convenient.

[0051] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
