Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a portable upper limb joint rehabilitation training device. Background Technology

[0002] In the context of rehabilitation training or daily activities for patients undergoing upper limb joint rehabilitation, there is a need for a portable device that can simultaneously provide rehabilitation training for the shoulder, elbow, wrist, and finger joints to improve rehabilitation efficiency and convenience. However, some problems exist in existing technologies: First, most existing upper limb joint rehabilitation training devices are single-joint dedicated models with limited functions. Patients need to purchase multiple devices, which is not only costly but also makes the devices scattered and difficult to carry, thus failing to meet the needs of simultaneous rehabilitation training for multiple joints.

[0003] Secondly, most existing upper limb joint rehabilitation training devices are large, fixed equipment that are bulky and non-wearable, making them unsuitable for the diverse training needs of patients at home or when they are out. In particular, the shoulder joint training section lacks a wearable and portable resistance reaction structure, making it difficult to achieve multi-directional targeted rehabilitation training.

[0004] Therefore, there is an urgent need to design a portable upper limb joint rehabilitation training device that can solve the above technical problems. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a portable upper limb joint rehabilitation training device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model mainly provides the following technical solutions: A portable upper limb joint rehabilitation training device includes a main body and further includes: Wearable adaptation mechanisms and resistance training mechanisms; among which: The wearable adapter includes a wearable component located on the outside of the main body and a fixing component located on its end side; The resistance training mechanism includes a positioning component fixedly mounted on the wearable components and a traction component connected between the wearable components.

[0007] Furthermore, the wearable component includes upper arm sleeves on the upper part of the left and right sides of the main body, lower arm sleeves on the lower part, and five finger sleeves on the inner side of the lower end of the forearm. A waist support belt is provided on the inner middle of the body.

[0008] Furthermore, the fixing component includes inner diameter adjustment straps at the upper and lower ends of the upper arm and forearm fitting sleeves, respectively; The waist fixing belt has a loop at one end, and the other end passes through the loop and wraps around to be glued.

[0009] Furthermore, the positioning component includes hooks a and b, which are respectively fixedly connected to the inner outer walls of the upper arm and forearm sleeves via mounting plates. The waist fixing belt has hooks c fixedly connected to the left and right outer walls via mounting plates.

[0010] Furthermore, the pulling assembly includes a pulling spring a between hook a and hook b, and a pulling spring b between hook a and hook c; An elastic cord is provided between the inner side of the lower end of the forearm adapter sleeve and the outer wall of the finger sleeve.

[0011] Furthermore, the upper arm sleeve, forearm sleeve, and finger cots are all made of materials with high elasticity and high breathability. The tension springs and elastic ropes are made of materials with high resilience and high fatigue resistance.

[0012] Compared with the prior art, the beneficial effects of this utility model are mainly reflected in: Firstly, compared to existing upper limb joint rehabilitation training devices, which are mostly single-joint specialized, have limited functionality and are scattered and difficult to carry, this utility model proposes a portable upper limb joint rehabilitation training device. It employs a wearable adapter mechanism, combining a wearable component consisting of an upper arm adapter sleeve, a forearm adapter sleeve, finger sleeves, and a waist support belt with a traction component containing multiple hooks, springs, and elastic ropes. This effectively achieves simultaneous rehabilitation training for multiple joints, including the shoulder, elbow, wrist, and fingers, eliminating the need for multiple devices. Furthermore, the components can be disassembled and stored, greatly improving portability and cost-effectiveness.

[0013] Secondly, compared to existing upper limb joint rehabilitation training devices, which are mostly large, fixed, and non-wearable, especially shoulder joint training devices, which lack portable resistance reaction structures, this invention provides a portable upper limb joint rehabilitation training device that employs a resistance training mechanism. Through the elastic connection between the multi-directional hooks of the waist strap and the hooks of the upper arm sleeve, it effectively achieves wearable resistance training in multiple directions, including shoulder flexion, extension, abduction, and adduction. Simultaneously, the entire device is lightweight and portable, perfectly suited for diverse rehabilitation scenarios such as home and outings.

Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0016] like Figure 1-2 As shown, this utility model discloses a portable upper limb joint rehabilitation training device, which includes a main body 1 and further includes: Wearable adapter 2 and resistance training mechanism 3; wherein: The wearable adapter 2 includes a wearable component 21 located on the outside of the main body 1 and a fixing component 22 located on its end side. The wearable adapter 2 is responsible for achieving stable wearing of the limb and the device. The wearable component 21 directly contacts the upper limb and waist of the human body to form the wearable base. The fixing component 22 is used to adjust the tightness of the wearable component 21 to ensure that users of different body types can wear it stably. The resistance training mechanism 3 includes a positioning component 31 fixedly installed on the wearable component 21 and a traction component 32 connected between the wearable components 21. The resistance training mechanism 3 is responsible for providing controllable resistance for joint training. The positioning component 31 provides a precise mounting fulcrum for the traction component 32 to ensure the stability of the traction direction. The traction component 32 generates resistance through elastic deformation and acts directly on the joint to achieve the training function.

[0017] like Figure 1 , 2 As shown, in this embodiment, the wearable component 21 includes upper arm adapter sleeves 211 respectively provided on the upper left and right sides of the main body 1. The upper arm adapter sleeves 211 have a tubular structure and can wrap the area of ​​the upper arm from the shoulder to the elbow, providing close support for the upper arm. The lower part is provided with forearm adapter sleeves 212, which correspond to the position of the forearm from the elbow to the wrist, and form a segmented fixation with the upper arm adapter sleeves 211. The inner side of the lower end of the forearm is provided with 5 finger sleeves 213, which correspond to the thumb, index finger, middle finger, ring finger and little finger respectively. They are fitted in the middle of the finger joints and can independently follow the movement of the fingers, ensuring that each finger can accurately bear force during training. The inner middle of the main body 1 is provided with a waist fixing belt 214. The waist fixing belt 214 is long and wraps around the waist, serving as a support point for the reaction force during shoulder joint training.

[0018] like Figure 1 , 2 As shown, in this embodiment, the fixing component 22 includes inner diameter adjustment straps 221 at the upper and lower ends of the upper arm fitting sleeve 211 and the forearm fitting sleeve 212, respectively. The inner diameter adjustment straps 221 adopt Velcro or other movable connection structures, with one end being a rough surface and the other end being a hook surface. By adjusting the adhesive length, the inner diameter size of the sleeve can be flexibly changed to adapt to the differences in the thickness of the upper arm and forearm of different users, ensuring that the sleeve fits the limb without slipping, while avoiding excessive tightness that compresses blood circulation. The waist fixing belt 214 has a collar 222 at one end, and the other end passes through the collar 222 and wraps around to connect. The wrapping and adhesive connection can quickly complete the fixing and is easy to disassemble. It is suitable for a wide range of waist sizes and ensures the stability of the waist fixing.

[0019] like Figure 1 , 2 As shown, in this embodiment, the positioning component 31 includes hooks a312 and b313 that are fixedly connected to the inner outer walls of the upper arm sleeve 211 and the forearm sleeve 212 respectively via a mounting plate 311. The mounting plate 311 is a sheet-like structure that is fixed to the sleeve by sewing or gluing, thereby increasing the connection area between the hook and the sleeve and preventing the hook from falling off when under force. Hooks a312 and b313 provide coaxial connection points for the traction component of elbow joint training. The left and right outer walls of the waist fixation belt 214 are fixedly connected to the hooks c314 by the mounting plate 311. The hooks c314 are stably fixed to the left and right sides of the waist fixation belt 214 by the mounting plate 311, providing a flexible connection fulcrum for multi-directional resistance training of the shoulders.

[0020] like Figure 1 , 2 As shown, in this embodiment, the traction component 32 includes a traction spring a321 between hook a312 and hook b313. The traction spring a321 has hook structures at both ends, which can be quickly hooked onto hook a312 and hook b313. When the elbow joint performs flexion and extension movements, the spring is stretched or contracted, generating reverse resistance through its own elasticity. The magnitude of the resistance changes with the stretching amplitude, which can adapt to the training intensity requirements of different rehabilitation stages and achieve targeted training of elbow joint range of motion and muscle strength. A traction spring b322 is provided between hook a312 and hook c314. The traction spring b322 also has hooks at both ends. One end is connected to hook a of the upper arm, and the other end is connected to hook c314 of the waist. When the shoulder joint performs flexion, abduction, extension and other movements, the spring is stretched to generate elastic resistance. The stable support of the waist forms a reaction force, and the shoulder muscle group is exercised through resistance feedback to improve the shoulder joint's range of motion. An elastic cord 323 is provided between the inner side of the lower end of the forearm adapter sleeve 212 and the outer wall of the finger sleeve 213. One end of the elastic cord 323 is fixed to the forearm adapter sleeve 212 near the wrist, and the other end is connected to the outer side of the finger sleeve 213. Each finger sleeve 213 corresponds to an independent elastic cord 323. When the fingers perform flexion and extension movements or the wrist performs rotation and flexion and extension movements, the elastic cord 323 is pulled to generate elastic tension, which can train the flexibility and muscle strength of the finger joints, and can also drive the coordinated movement of the fingers through the wrist, thus simultaneously exercising the wrist muscles.

[0021] like Figure 1 , 2 As shown, in this embodiment, the upper arm sleeve 211, the forearm sleeve 212, and the finger sleeve 213 are all made of a material with high elasticity and high breathability. The high elasticity ensures that the sleeve and finger sleeve 213 can naturally deform with limb movement, conform to the limb contours of different users without causing a feeling of restriction, and ensure the freedom of joint movement; the high breathability can reduce the stuffiness when wearing, and promote air circulation through the porous structure of the material, avoid the accumulation of sweat caused by long-term training, and improve wearing comfort. The tension spring and elastic rope 323 are both made of materials with high resilience and high fatigue resistance. High resilience ensures that the resistance can be generated stably and linearly during tensioning to meet the needs of different training intensities. High fatigue resistance ensures that the material performance is not easily degraded during long-term repeated stretching and contraction, avoiding the decrease in elasticity or breakage due to frequent use, and extending the service life of the device.

[0022] The working principle and usage process of this technical solution are as follows: During use, the user first puts the upper arm sleeve 211 and the forearm sleeve 212 on the corresponding limbs, and adjusts them with the inner diameter adjustment strap 221 until they fit snugly and are not loose, ensuring that the sleeves will not slip off or compress blood vessels and affect blood circulation; then, the finger sleeves 213 are put on the middle of the five finger joints to ensure that each finger is evenly stressed, avoiding excessive or insufficient stress on a single finger, and ensuring the balance of finger joint training; finally, the waist fixing strap 214 is wrapped around the waist and fixed by the loop 222 and the adhesive structure to ensure stable waist support and provide a reliable reaction force basis for shoulder joint training. Subsequently, the tensioning component 32 is connected according to training needs: For elbow joint training, the two ends of the tension spring a321 are hung on hooks a312 and b313 respectively. The tension spring a321 is stretched by flexing and extending the elbow joint, using elastic resistance to exercise the elbow muscles. During flexion and extension, the resistance of the tension spring a321 changes with the angle, which can gradually improve the range of motion and muscle strength of the elbow joint; For shoulder joint training, the corresponding hook c314 is selected, the tension spring a321 is removed, and the tension spring b322 is connected to the hook. A312 and hook C314, through multi-directional shoulder joint movement, generate resistance in the tension spring B322 to achieve shoulder training. It can adapt to the movement needs of the shoulder joint in different directions and specifically improve shoulder function. For wrist and finger joint training, the elastic rope 323 between the forearm-fitting sleeve 212 and finger sleeve 213 is used. The elastic rope 323 is pulled by finger flexion and extension or wrist movement to achieve the training effect. The independent elastic rope 323 design can realize single finger training or multi-finger coordinated training, while also taking into account wrist range of motion training. During training, the elastic material of each wearable component ensures free movement of the limbs, the breathability enhances comfort, the anti-fatigue properties of the traction component ensure stable resistance, the overall structure is lightweight, and each component can be disassembled and stored for easy carrying. It can meet the upper limb multi-joint rehabilitation training needs of users in various scenarios such as home and outdoors.

[0023] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
