Description

Technical Field

[0001] The invention relates to the technical field of medical training equipment for limbs of burn patients, in particular to a rehabilitation training device for preventing joint stiffness of burn patients. Background Art

[0002] Burns refer to tissue damage caused by heat, electric current, chemicals, lasers, radiation, etc. Thermal burns refer to tissue damage caused by hot liquids (water, soup, oil, etc.), steam, high-temperature gas, flame, hot metal liquid or solid. Burns, which are usually called or in a narrow sense, generally refer to burns caused by heat. In clinical practice, burns caused by hot liquids and steam are also called scalds. Burns caused by other reasons are named according to the cause, such as electrical burns, chemical burns, etc.

[0003] Since the skin tissue is damaged after a burn, scar tissue will form during the healing process. Scar tissue lacks elasticity and will gradually shrink, resulting in limited joint movement and contracture deformities. In addition, due to pain, reduced limb movement and other reasons, muscles will atrophy due to disuse, resulting in decreased muscle strength. Scar tissue will also continue to pull the tissues around the joints, resulting in a continuous decrease in the range of joint movement. Therefore, limb rehabilitation training for burn patients is very necessary. Through limb rehabilitation training, such as flexion and extension of joints, rotation and other activities, a certain amount of traction can be applied to scar tissue to prevent excessive contracture, maintain the normal range of motion of the joints, and prevent muscle atrophy from causing joint stiffness. Rehabilitation training can stimulate muscle contraction, promote muscle blood circulation, increase muscle nutrient supply, prevent muscle atrophy, and gradually restore muscle strength to reduce the risk of joint injury through active exercise and resistance exercise.

[0004] Rehabilitation exercises for burn patients can be carried out with the aid of equipment. For example, the prior art "An integrated rehabilitation device for limb burns" (publication number: CN 112933533 A) designs a device that can fix the human legs and perform leg walking training with a predetermined resistance, which can realize the function of automatically adjusting the intensity of exercise according to the patient's burn condition. However, the prior art still has the following technical problems:

[0005] 1. Poor resistance adaptation affects the effect of rehabilitation training. The existing technology uses sensors to monitor the tension of patients during training, and then compares it with the preset tension in the storage module to adjust the appropriate training resistance intensity to improve the training effect. However, due to individual differences among patients, the degree of adaptation and demand for training resistance are also different. The preset tension value in the storage module cannot be adapted to everyone. Therefore, if the tension during training is used as a benchmark for adjustment, some patients may have too little training resistance and cannot achieve sufficient training intensity, resulting in slow improvement in muscle strength and joint mobility, and hindered rehabilitation progress; while other patients may have too much training resistance, which exceeds the body's tolerance range, aggravates physical fatigue, and finds it difficult to stick to the training plan, and also cannot achieve the expected rehabilitation training effect.

[0006] 2. The device is inconvenient to use and has poor comfort. The overall structure of the device is relatively large, not flexible and light enough, and patients may feel restricted in their movements during use. In addition, the use of fixed belts and winches in the fixed module to fix the patient's limbs may make the patient feel restrained and uncomfortable, affecting the enthusiasm and sustainability of rehabilitation training.

[0007] 3. There are few limb training programs and insufficient applicability. The existing devices focus on rehabilitation training for the legs, but the burn sites, degrees and rehabilitation stages of different burn patients vary greatly. For different types of burn patients, there are few rehabilitation training programs and they cannot meet the different needs of patients. Summary of the invention

[0008] The present invention provides a rehabilitation training device for preventing joint stiffness in burn patients, which can solve the problem that the rehabilitation devices in the prior art have insufficient applicability to limb training parts and cannot adjust the training intensity for different patients, thereby affecting the rehabilitation of patients.

[0009] The present application provides the following technical solutions: a rehabilitation training device for preventing joint stiffness in burn patients, comprising a limb training unit, a monitoring unit and an intelligent control unit;

[0010] It also includes a bracket, the limb training unit is fixed on the bracket, and the limb training unit includes a limb comprehensive training module, an arm opening and closing training module, and an arm lifting training module;

[0011] The monitoring unit is used to monitor the patient's heart rate, blood pressure, and blood sugar;

[0012] The intelligent control unit is used to automatically adjust the training parameters of the limb training unit according to the monitoring information of the monitoring unit; the training parameters include training intensity, training frequency, training duration, and training resistance.

[0013] Beneficial effects:

[0014] 1. Accurately adapt to individuals and improve rehabilitation effects: Different from the existing technology that simply relies on preset tension values ​​to control training resistance, the intelligent control unit of the device of the present invention can comprehensively monitor the heart rate, blood pressure, blood sugar and other multi-dimensional physical indicators fed back by the monitoring unit, and can more comprehensively consider the individual differences of patients and accurately adapt to each patient's unique needs for training resistance. For example, for burn patients with weak bodies and poor endurance, even if the tension during training meets the preset value, if the heart rate is too fast and the blood pressure fluctuates abnormally, the intelligent control unit can also timely determine that the current resistance is too large, automatically reduce the training resistance, avoid excessive fatigue of the body due to resistance mismatch, and make it difficult to persist in training, and ensure the smooth progress of rehabilitation training. At the same time, during the training process, as the patient's physical functions gradually recover, the adaptability to training resistance will also change, and the intelligent control unit can flexibly adjust the training resistance intensity according to the patient's real-time physical condition, thereby effectively improving the rehabilitation training effect.

[0015] 2. Integrate training programs to meet different training needs. The limb training unit includes limb comprehensive training module, arm opening and closing training module and arm lifting training module, which can provide diversified training methods for burn patients with different burn sites and rehabilitation needs. The limb comprehensive training module can conduct comprehensive training of upper and lower limbs to promote overall limb function recovery; the arm opening and closing training module helps to exercise arm strength and joint mobility and improve arm function; the arm lifting training module can effectively stretch arm muscles and joints and prevent arm joint stiffness, fully meeting patients' rehabilitation training needs and ensuring training results.

[0016] Furthermore, the comprehensive limb training module includes a shell, a handwheel shaft rotatably connected to the top of the shell, and a caster shaft rotatably connected to the bottom of the shell, a disc is fixed on the handwheel shaft and the caster shaft, an annular groove is provided on the outer periphery of the disc, a first electric cylinder is also provided in the shell, a slider is fixed on the telescopic rod of the first electric cylinder, the slider is slidably connected to the inner wall of the shell, belts are fixed at both ends of the slider, and the belts are arranged in the annular groove.

[0017] Beneficial effects: Through the design of the handwheel shaft and the caster shaft, the user can use the strength of the hands and feet during operation, realizing the rehabilitation training of the upper and lower limb joints, which helps to promote blood circulation throughout the body, exercise the muscle strength and joint flexibility of the hands and legs, enhance the coordination of the body, and accelerate the rehabilitation process; at the same time, the first electric cylinder controls the sliding of the slider through the telescopic rod, and then adjusts the tightness of the belt in the annular groove of the disc to achieve the adjustment of the training resistance, so that the intelligent control module can adjust the training intensity at any time according to the patient's physical data, meet the training needs of different stages, and improve the training effect.

[0018] Furthermore, the arm opening and closing training module includes a second electric cylinder fixed on the bracket, a support block fixed to the end of the telescopic rod of the second electric cylinder, a rotating shaft fixed above the support block, a swing arm rotatably connected to the rotating shaft, and a handle fixed on the swing arm.

[0019] Beneficial effects: This module is specially designed for arms. Patients can hold the handles with their hands and perform horizontal abduction and adduction movements, so as to specifically train the arm muscle strength, especially the shoulder, elbow and wrist muscle groups. At the same time, it can also improve the mobility of the arm joints, which has a direct promoting effect on the recovery of arm function after burns.

[0020] Furthermore, tension springs are fixed on both sides of the swing arm respectively, and a third electric cylinder is provided at the other end of the tension spring. The third electric cylinder is fixed in the bracket, and the telescopic rod of the third electric cylinder is fixedly connected to the tension spring.

[0021] Beneficial effects: The third electric cylinder can accurately control the stretching degree of the tension spring, so as to accurately adjust the resistance during training; compared with simply relying on the second electric cylinder to adjust the resistance of the swing arm, adding the combination of the tension spring and the third electric cylinder makes the resistance adjustment more flexible and meticulous; the training resistance can be set more accurately according to the patient's specific rehabilitation stage and physical condition to meet the personalized needs of different patients.

[0022] Furthermore, the arm lifting training module includes a spring fixed above the bracket and a pull ring fixed below the spring. The springs are symmetrically arranged on both sides above the pull ring, and a fourth electric cylinder is also fixed above the bracket. The end of the spring away from the pull ring is fixedly connected to the telescopic rod of the fourth electric cylinder.

[0023] Beneficial effects: Through the setting of pull rings and springs, the module allows patients to perform arm lifting movements, which can specifically exercise the biceps, triceps and other major muscle groups of the arms, while improving the flexibility and stretching ability of the arm joints. The presence of the fourth electric cylinder allows the stretching degree of the spring to be precisely controlled, changing the initial tension and stretching range of the spring, thereby flexibly adjusting the training intensity to meet the exercise needs of different patients at different rehabilitation stages.

[0024] Furthermore, a seat module is provided on the bracket, including a positioning block fixed at the bottom of the bracket, guide columns fixed around the positioning block and a seat cushion slidably connected to the guide columns. A fifth electric cylinder is also fixed on the positioning block, and the telescopic rod of the fifth electric cylinder is fixed to the bottom of the seat cushion.

[0025] Beneficial effects: There are differences in height and body shape among different burn patients. The seat adjustment module can adapt well to such individual differences. Regardless of whether the patient is tall or short, the seat cushion height can be adjusted to maintain a suitable position relationship between the body and the training modules such as the arm opening and closing training module and the arm pulling training module, ensuring that the patient can perform training correctly and effectively, giving full play to the role of each training module, and improving the pertinence and effectiveness of rehabilitation training.

[0026] Furthermore, a distance adjustment module is also provided at the bottom of the bracket, including a motor fixed in the bracket and a screw rod fixedly connected to the motor main shaft, the end of the screw rod away from the motor is rotatably connected to the bracket, the rod portion of the screw rod is threadedly connected to a slide seat, the slide seat is slidably connected to the bracket, and the bottom of the shell extends into the bracket and is fixed on the slide seat.

[0027] Beneficial effects: Different burn patients have different body shapes. The distance adjustment module can be driven by a motor to rotate the screw rod, driving the slide to slide on the bracket, and then adjusting the distance between the outer shell and the limb comprehensive training module and the seat module. This allows patients to adjust the limb comprehensive training module to a position that best suits them based on the range of motion of their arms and legs, strength and other factors, thereby achieving a personalized training experience and improving the effectiveness and comfort of the training.
