DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

Embodiment 1

Please refer to Figures 1-4. The utility model provides a technical solution: a wearable upper limb rehabilitation device, comprising: an upper bracket 001;

Also includes:

The lower bracket 002 is arranged at the lower side of the upper bracket 001 and is used to support and protect the forearm;

The rehabilitation component 003 is arranged on one side of the upper bracket 001 and the lower bracket 002, and is used to connect the upper bracket 001 and the lower bracket 002. The rehabilitation component 003 includes a connecting rod 301, a movable cylinder 302, a movable plate 303, a telescopic rod 304 and a reset spring 305. Two connecting rods 301 are provided. The two connecting rods 301 are respectively arranged at the rear ends of the upper bracket 001 and the lower bracket 002, and are movably connected with the upper bracket 001 and the lower bracket 002. The top end of one of the connecting rods 301 is fixedly connected to the movable cylinder 302, and the inner wall of the movable cylinder 302 is slidably connected to the movable plate 303. The top end of the movable plate 303 is fixedly connected to the telescopic rod 304, and the telescopic rod 304 penetrates the movable cylinder 302. A reset spring 305 is provided on the lower side of the telescopic rod 304, and one end of the reset spring 305 is fixedly connected to the movable plate 303, and the other end is fixedly connected to the movable cylinder 302.

Among them, the upper bracket 001 and the lower bracket 002 have the same structure. The patient can wear the upper bracket 001 and the lower bracket 002 on the upper arm and forearm respectively. When the patient's forearm is stretched out to do flexion and extension exercises, the rehabilitation component 003 will help the patient to do flexion and extension exercises, simulating the patient's specific movements in life, and thereby restore and reconstruct the patient's muscle, ligament and joint mobility.

The inner wall of the upper bracket 001 is provided with a latex pad 110, and the inner wall of the latex pad 110 is distributed with medical rings 120 in a circular array.

Among them, the latex pad 110 is convenient for improving the comfort of patients, and the patients can fill the medical ring 120 with the medicines they need, so as to relieve muscle soreness for patients when they do rehabilitation exercises, provide analgesic effect, and make the rehabilitation training more effective.

Retractable straps 130 extend from both sides of the upper end of the upper bracket 001, and connecting rings 140 are rotatably connected to both sides of the lower end of the upper bracket 001. The retractable straps 130 penetrate the connecting rings 140, and Velcro 150 is provided at both ends of the outer wall of the retractable straps 130.

When in use, the patient puts the upper arm and the forearm into the upper bracket 001 and the lower bracket 002 respectively, and then passes the retractable belt 130 through the connecting ring 140, tightly wraps the arm with the retractable belt 130, and then sticks the two ends of the retractable belt 130 with Velcro 150, and then the device can be worn on the injured arm of the patient.

A buffer spring 310 is disposed on the upper side of the telescopic rod 304 . One end of the buffer spring 310 is fixedly connected to the other connecting rod 301 , and the other end of the buffer spring 310 is fixedly connected to the movable cylinder 302 .

Among them, when the patient extends his arm, the patient needs to overcome the upward elastic force of the return spring 305, so that the movable cylinder 302 slides on the outer wall of the movable rod and slides to the bottom, fully exercising and improving the exercise effect. When the patient retracts his arm, the upward elastic force of the return spring 305 helps the patient to retract his arm upward, helping the patient to do rehabilitation training. The setting is safe and reliable, helping the patient to conduct repeatable and task-oriented training, promoting the mobility of the muscles, ligaments and joints of the shoulders and upper limbs, improving the coordination, muscle strength and range of joint movement of the upper limbs, and helping the patient rebuild confidence after injury. At the same time, the setting of the buffer spring 310 can absorb a certain amount of pressure from the return spring 305 to avoid secondary strain of the patient during exercise. At the same time, the structure in the setting is low-cost, reduces the burden on patients, and is convenient for mass production in the market.

A positioning plate 320 is provided below the movable plate 303, and the positioning plate 320 forms a sliding connection with the movable cylinder 302. Movable grooves 321 are provided on both sides of the movable cylinder 302. Both ends of the positioning plate 320 pass through the movable grooves 321. Both ends of the positioning plate 320 are fixedly connected with adjusting screws 322, and the internal threads of the adjusting screws 322 are connected with fastening nuts 323.

Among them, the positioning plate 320 slides downward in the movable groove 321, and the two fastening nuts 323 are respectively connected to the adjusting screw 322, so that the adjusting screw 322 presses the movable cylinder 302 tightly, thereby fixing the position of the positioning plate 320. The more the positioning plate 320 moves downward, the larger the range of motion left for the movable plate 303, and then the range of motion of the patient's arm is expanded accordingly. At the same time, the upward elastic force of the reset spring 305 becomes stronger and stronger, and the force required for the patient's training becomes stronger and stronger. The doctor can gradually adjust the positioning plate 320 downward according to the patient's condition, so that the patient's training range of motion becomes larger and larger, and the intensity becomes higher and higher, which promotes the recovery and functional recovery of muscles and ligaments. At the same time, the patient can gradually adapt to the strength of the device and improve the safety of the patient's use.

The left and right sides of the positioning plate 320 are both rotatably connected with clamping blocks 324 , and the positioning plate 320 is engaged with the movable plate 303 via the clamping blocks 324 .

Among them, when the patient's training amount reaches the standard, the patient can rotate the blocks 324 on both sides of the positioning plate 320 so that the blocks 324 clamp the movable plate 303, thereby positioning the movable plate 303, and the rehabilitation component 003 no longer helps the patient to move, and the device can fix the patient's upper arm and forearm to prevent the patient from overtraining and causing muscle strain in the patient, thereby ensuring the safety and effectiveness of the device.

Embodiment 2

As shown in FIG5 , in the second embodiment, other structures remain unchanged. What is different from the first embodiment is that a mounting screw 004 can be provided at the rear end of the connection between the upper bracket 001 and the connecting block. The patient can remove the mounting screw 004 to cancel the connection between the upper bracket 001 and the connecting block, and then the patient can disassemble the upper bracket 001, the lower bracket 002 and the rehabilitation component 003 respectively and store them individually, so that the patient can move and carry the new type for use.
