Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation medicine, in particular to a cross-joint wearable rehabilitation exercise device for resisting scar contracture. Background Art

[0002] After the repair of skin and soft tissue burns, systematic and precise rehabilitation exercises are required to combat possible scar hyperplasia and contracture. Scar hyperplasia and contracture are particularly serious for joints and areas of frequent activity, such as wrists and elbows. Injuries to these areas not only affect daily activities, but may also lead to disuse atrophy of related muscles due to long-term inactivity, further exacerbating functional impairment and even leading to permanent disability. The goal of rehabilitation exercises is to promote the softening of scar tissue and increase its elasticity through physical means, such as stretching, strengthening, and coordination training, while enhancing the strength and flexibility of surrounding muscles to combat the limitations caused by scar hyperplasia. This process needs to last for several months or even longer to ensure the best recovery effect; therefore, after systematic medical treatment, timely and precise anti-scar rehabilitation exercises become the key to preventing or alleviating these complications.

[0003] However, in a field environment, this demand faces huge challenges; in the prior art, multi-joint exercise equipment often does not fit the patient's joints during exercise, thereby rubbing the patient's arms and causing a bad experience for the patient. If the equipment can take into account the exercise of multiple joints, it is generally bulky and inconvenient to carry. If the equipment is easy to carry, it often cannot take into account multiple joints at the same time, and the patient sometimes cannot control the extent of arm extension when using it, which can easily lead to strain due to excessive arm extension. Therefore, it is particularly important to develop a device that is easy to carry and can effectively implement rehabilitation exercises in various field environments. Summary of the invention

[0004] The present invention provides a cross-joint wearable rehabilitation exercise device for resisting scar contracture, so as to solve the problems existing in the background technology.

[0008] A limiting rope for limiting the stretching length of the elastic band is connected between the two ends of the elastic band;

[0009] The storage assembly includes a limit block 1 fixedly connected to the top of the strap 4, a spring fixedly connected inside the limit block 1, an end of the spring away from the bottom of the limit block 1 fixedly connected to an L rod, the L rod is slidably connected inside the limit block 1, the bottom of the limit block 1 is fixedly connected to the limit block 2, and the bottom of the strap 4 is fixedly connected to a telescopic rod;

[0010] The massage component includes a protective belt fixedly connected between the second strap and the third strap and between the third strap and the fourth strap. A plurality of fixed blocks are arranged between the second strap and the third strap and between the third strap and the fourth strap, and two adjacent fixed blocks are adjacent to each other through flexible parts. The fixed blocks near the positions of the second strap, the third strap and the fourth strap are respectively fixedly connected to the second strap, the third strap and the fourth strap, and the fixed blocks are rotatably connected to a rotating rod on one side close to the protective belt, and the rotating rods are fixedly connected to the adjusting rope. The end of the rotating rod away from the fixed block passes through the protective belt, and the passing end is connected to a flexible massage head.

[0011] Furthermore, a controller is provided on the other side of the strap one, an air pump is provided in the controller, the strap one and the strap two are connected via a connecting belt one, and the air pump is connected to each of the airbag rings.

[0012] Furthermore, the controller is provided with a Bluetooth module for connecting to a mobile device.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the patient's arm is extended, the adjustment rope of the present invention extends. At this time, the patient's arm stretches the adjustment rope, and the adjustment rope passes through the connecting sleeve 1 and the connecting sleeve 2 to stretch the elastic belt. Since the self-locking motor only releases part of the adjustment rope, the elastic belt provides a buffering effect for the patient's arm when the patient extends, and when the patient's arm is bent, the elastic belt assists the bending of the patient's arm.

[0016] 2. The present invention releases the adjustment rope through a self-locking motor to control the length of the adjustment rope between the strap four and the connecting sleeve one, thereby limiting the maximum bending angle of the arm to prevent muscle strain caused by excessive movement. When the patient is exercising, the massage component can relax the fibrous tissue around the patient's scar to a certain extent, thereby softening the scar, helping to gradually smooth the scar and improve its appearance. When the patient's arm is straightened, the fixed block supports the patient's arm, ensuring the stability and comfort of the arm in the extended state. When the patient bends his arm, the flexible parts between each fixed block will bend to adapt to the natural movement trajectory of the arm.

[0017] 3. The present invention pulls the L rod in a direction away from the strap four and pulls the spring, and at the same time places the strap two on the inner side of the telescopic rod, and then pulls the telescopic rod so that the inner block on the output end of the telescopic rod is inserted into the square groove two, and then releases the L rod, the spring loses its tension and pulls the L rod in the direction of the strap four, so that the outer block on the output end of the telescopic rod is inserted into the square groove one, and then the device is folded up for the patient to carry.

The strap 1 and the strap 2 2 are connected by a connecting belt 12, and the air pump is connected to each of the airbag rings 7.

[0033] As a preferred technical solution of the present invention, the controller 11 is provided with a Bluetooth module for connecting with a mobile device.

[0034] As a preferred technical solution of the present invention, a square groove 1 531 is provided on the short side of the L rod 53, a square groove 2 541 is provided on the limit block 2 54 at a position opposite to the square groove 1 531, and blocks 551 are fixedly connected to both sides of the output end of the telescopic rod 55, and the size of the block 551 is the same as that of the square groove 1 531 and the square groove 2 541.

[0035] Working principle:

[0036] like Figure 1 As shown, the patient first puts strap 1 on the shoulder, and then puts strap 4 4, strap 3 3 and strap 2 2 on the arm in sequence. When strap 4 4 is put on the wrist joint, the air pump in the controller 11 is started to make the airbag ring 7 on strap 4 4 expand and fit the patient's arm, so that strap 4 4, strap 3 3 and strap 2 2 are fixed on the patient's arm.

[0037] like Figure 1 and Figure 3-Figure 5 As shown, when the wearing is completed, the patient starts the self-locking motor 26 to release the adjustment rope 24, and controls the length of the adjustment rope 24 between the strap four 4 and the connecting sleeve one 22, so as to limit the maximum bending angle of the arm to prevent muscle strain caused by excessive movement. When the patient's arm is stretched, the adjustment rope 24 is extended. At this time, the patient's arm stretches the adjustment rope 24, and the adjustment rope 24 passes through the connecting sleeve one 22 and the connecting sleeve two 23 to stretch the elastic belt 27. Since the self-locking motor 26 only releases part of the adjustment rope 24, the elastic belt 27 provides a buffering effect for the patient's arm when the patient stretches, and when the patient's arm is bent, the elastic belt 27 plays a role in assisting the bending of the patient's arm;

[0038] During the patient's exercise, the adjusting rope 24 slides in the connecting sleeve 1 22 and drives the rotating rod 62 between the strap 2 2 and the strap 3 3 to rotate. Then the adjusting rope 24 passes through the connecting sleeve 23 to drive the rotating rod 62 between the strap 3 3 and the strap 4 4 to rotate. When the rotating rod 62 rotates, it drives the massage head 621 to massage the patient's arm and protects the patient's arm through the protective pad belt 612. When the patient performs rehabilitation exercises, the fibrous tissue around the patient's scar is relaxed to a certain extent through massage, thereby achieving the purpose of softening and helping to restore the scar. When the adjusting rope 24 drives the rotating rod 62 to rotate, the elastic belt 27 assists the rotating rod 62 to rotate. At the same time, when the patient's arm is straightened, the fixed block 63 supports the patient's arm, ensuring the stability and comfort of the arm in the extended state. When the patient bends his arm, the flexible member 631 between each fixed block 63 will bend to adapt to the natural movement trajectory of the arm.

[0039] like Figure 2As shown, the Bluetooth module uploads the arm movement data detected by the acceleration sensor and the gyroscope sensor to the App in the mobile device through the mobile device to facilitate sharing of the data with the cloud. At the same time, the doctor determines whether the patient's arm is suitable for full extension based on the received data, thereby controlling the extension length of the adjustment rope 24, and then controlling the extendable length of the patient's arm.

[0040] like Figure 2-Figure 3 As shown, when the patient puts up the device, the strap four 4 can be inserted into the strap three 3, and the strap three 3 can be inserted into the strap two 2, and then the L rod 53 can be pulled in the direction away from the strap four 4, and the spring 52 can be pulled. At the same time, the strap two 2 can be placed on the inner side of the telescopic rod 55, and then the telescopic rod 55 can be pulled so that the inner block 551 on the output end of the telescopic rod 55 can be inserted into the square groove two 541. Then, the L rod 53 is released, and the spring 52 loses its tension and pulls the L rod 53 in the direction of the strap four 4, so that the outer block 551 on the output end of the telescopic rod 55 can be inserted into the square groove one 531, and then the device can be folded up for the patient to carry.

[0041] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
