Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation devices, and more specifically, to a treatment assistance device for children with severe movement disorders and an assistance method thereof. Background Art

[0002] Children with severe movement disorders are a group of children with serious movement function disorders. The movement disorders of such children are manifested in aspects such as gross motor function, fine motor function, oral movement control, respiratory movement, and gastrointestinal movement, seriously endangering the growth and development of children and their daily lives. As they grow older, it brings great difficulties to parents in taking care of their daily lives and imposes a serious economic burden on society. Common diseases causing severe movement disorders in clinical treatment include cerebral palsy, neuromuscular diseases, and congenital genetic metabolic diseases, etc. How to improve the movement function of such children and improve their quality of life has become the focus and difficulty in the field of rehabilitation treatment.

[0003] Cerebral palsy is a group of persistent central motor and postural development disorders and activity limitation syndromes, which are caused by non - progressive damage to the brain of the developing fetus or infant. This syndrome persists throughout the life of the child. As a developmental disorder disease, cerebral palsy affects the lifelong development trajectory of children and their family life, cannot be cured, and there is no clear strategy for prevention. Symptomatic rehabilitation is the key to improving the movement disorders of children with cerebral palsy. Therefore, intervention measures must be considered from the perspective of promoting functional development and supporting family rehabilitation services. The severity of cerebral palsy is graded using the Gross Motor Function Classification System (GMFCS). Children at level IV and level V are severely affected by cerebral palsy. Such children severely lack the ability to control the head and trunk movements, have difficulty maintaining an upright body posture, are severely limited in self - movement, and lack the ability to live independently. Clinically, it can be seen that 30% of children with cerebral palsy need to move around in a wheelchair.

[0004] Genetic diseases mainly include chromosomal diseases and genetic metabolic diseases. Although their incidence rate is low, their disability rate is high, and early diagnosis and treatment are of great significance. Among them, chromosomal diseases refer to diseases with abnormal chromosome number and structure. Abnormal chromosome number and structure can co - exist, or either one can be abnormal, which can lead to diseases. The causes of this disease are diverse, belonging to a type of serious genetic disease. Severe chromosomal aberrations can cause early embryonic death and natural miscarriage. A small number of individuals with chromosomal aberrations can survive and be born smoothly, but they will show mental retardation, multiple organ dysfunction, and growth retardation after birth. Currently, more than a hundred chromosomal diseases are known, and according to literature reports, there are more than five hundred kinds of abnormal chromosome numbers and structures. Unfortunately, there is currently no effective treatment method for chromosomal diseases, and symptomatic treatment is used clinically. There are a wide variety of genetic metabolic diseases, with 400 - 500 common types. The prevalence of a single disease is relatively low, but the overall incidence rate is relatively high and the harm is serious.

[0005] Children with severe motor disorders have problems with muscle tone, muscle strength, and postural control. It is difficult for them to maintain body postures such as holding their heads upright, being unable to lift their heads, controlling the head in the midline position, having limited transfer ability in the lying position, abnormal excessive force in the limbs, and chewing and swallowing disorders. They may also have torsion spasm problems, which seriously affect the children's life activities. Long-term abnormal postures can lead to secondary musculoskeletal problems such as joint dislocation, contracture, and scoliosis. Studies have shown that the probability of children over 2 years old with severe motor disorders living to 20 years old is only 40%, while the probability of children with mild motor disorders living to 20 years old is 99%. From the perspective of improving the life activities of such children, we need to create more training methods suitable for such children that can elicit target motor responses and are of high quality, in order to relieve their pain and enable them to live a quality life.

[0006] For the routine rehabilitation training of such children, more single-joint and local activity-oriented training is adopted, which does not meet the goals we set for children with severe conditions. Therefore, the final curative effect is very unsatisfactory. During a large number of clinical observations and practices, it was found that isometric, eccentric, and closed-chain static training while maintaining joint stable postures can establish the postural control ability of such children. After the training and improvement of the children's motor ability, hand function, swallowing, sleep, and transfer ability are all improved, and the cognitive ability is also improved. Compared with conventional treatment, the effect is excellent. Therefore, on the basis of previous research, the training methods and auxiliary devices for children with severe conditions are designed, and the specific content is as follows:

[0007] In this process, due to the abnormal movement pattern of excessive force in the limbs of children with severe dyskinetic cerebral palsy, during the assisted active rehabilitation training of the children, the therapist in the front needs to support the child's head in a vertical position; the therapists on both sides need to fix the upper limb joints of the child, such as the shoulder joint, elbow joint, and wrist joint, to maintain the posture of 90° forward flexion of the shoulder joint, straightening of the elbow joint, and neutral position of the wrist joint. At the same time, it is necessary to fix the lower limb joints, such as the hip joint, knee joint, and ankle joint, to maintain the functional position of the lower limb joints; the therapist at the back needs to support the child's trunk and pelvis to promote the simultaneous force on both sides of the trunk to maintain an upright posture and prevent the occurrence of secondary scoliosis and hip joint dislocation. The entire treatment process requires the participation of at least four staff members or parents to maintain the correct alignment and posture of each joint of the child's body. Only in this posture can quality movements be generated, basic posture control ability be established, and the motor ability of such children be developed. Rehabilitation treatment is a long-term process, and such high-quality and high-intensity training is necessary every day, which makes therapists and parents feel overwhelmed. Can there be an auxiliary device that can maintain the body stability of severely ill children for daily training use to relieve the pressure on treatment staff and families, and at the same time can delay the training time and improve the rehabilitation treatment effect? In the existing technology, soft fixing devices are often used to fix the child's body, but the stability of such devices is weak, and additional auxiliary personnel are still required to fix the device, and it fails to trigger target-based motor performance, so the idea of developing an auxiliary device for the rehabilitation treatment of children with severe dyskinetic disorders has emerged.

In this embodiment, the chest restricting component is an arc-shaped fourth airbag 6. The fourth airbag 6 is adhesively fixed to the table board 15 and is communicated with an air pump. A fourth solenoid valve is provided at the communication part. The arm fixing component 2 is used to restrict the position of the child's arm and the angle of the elbow joint. The arm fixing component 2 includes two symmetrically arranged limiting tubes 21 made of elastic material. A group of fixing rings 24 are arranged in each of the limiting tubes 21. A number of fixing strips 23 made of plastic material are adhesively fixed to any one of the fixing rings 24 in each group of fixing rings 24. The fixing strips 23 are fixedly adhesively connected to the remaining fixing rings 24 in the group. Second airbags 22 are adhesively fixed to the fixing strips 23. The second airbags 22 are all communicated with the air pump. First solenoid valves are provided at the communication parts of the first airbag 83 and the second airbags 22 with the air pump; It also includes a control system, including a controller and a number of air pressure sensors; The air pressure sensors are all used to collect the air pressure information in the first airbag 83; The air pressure sensors, cylinders, electric cylinders, air pump and first solenoid valves are all electrically connected to the controller. The controller is used to judge the position of the child's joints according to the change trend of the air pressure information, so as to calculate the length of the child's calf and thigh, control the cylinder to work to adjust the distance between the fixing plate 82 and the stool 3, adjust the center of the joint elastic tube 81 to the position of the child's knee, calculate the required heights of the fixing table 1 and the stool 3 when the child's calf and thigh are perpendicular according to the length of the child's calf, control the electric cylinders to work according to the corresponding heights, and after the fixing table 1 and the stool 3 reach this height, control the air pump to work to pump gas into the first airbag 83, so that the first airbag 83 expands to clamp the lower limbs of the child, completing the fixation of the lower limbs of the child.,

[0044] The specific implementation process is as follows: When using this device, the user pulls out the support plate 42 from the placement groove according to the body shape of the child, so that the length of the support plate 42 is just enough to support the child's waist, and fixes the position of the support plate 42 using the locking slide rail. Then, the user starts the device and assists the child to sit on the stool 3, controls the air pump and the second solenoid valve to work, and pumps gas into the third airbag 43, so that the third airbag 43 unfolds and expands to drive the support plate 42 to rotate. During this process, the user assists the child's body to maintain a centered position. As the third airbag 43 expands, the support plate 42 rotates to the side of the child's waist, and at the same time, the third airbag 43 gradually contacts and squeezes the child's waist. At this time, the user closes the second solenoid valve to complete the fixation of the child's waist side. The setting of the third airbag 43 provides buffering for the child's waist, avoiding damage to the child's waist by the support plate 41 when the child struggles later, enabling the support plate 41 to adapt to the body shapes of different children. At the same time, during the filling process of the third airbag 43, it can drive the support plate 41 to rotate to the use position without manual adjustment by the user, reducing the operation steps of the user.

[0045] Subsequently, the user releases the child's waist, compares the length of the child's arm, and adjusts the position of the fixed table 1 to ensure that when the child straightens the arm, the wrist is not inside the arm fixing component 2. Then, the user presses one arm of the child to drive it into the fixing ring 24, making the child's arm in a relatively straight state. Then, the user presses the limiting tube 21, causing the fixing strip 23 to undergo plastic deformation and fit the skin of the child's arm. Subsequently, the user opens the first solenoid valve, enabling the air pump to pump gas into the second airbag 22. The second airbag 22 expands, driving the limiting tube 21 to deform. After the limiting tube 21 no longer undergoes obvious deformation, the first solenoid valve is closed to complete the fixation of this arm. Due to the design of the limiting tube 21 and the second airbag 22, under the action of air pressure, the second airbag 22 can limit the fixing strip 23 from deforming again, effectively reducing the deformation of the fixing strip 23 in the direction of the limiting tube 21 during the subsequent struggle of the child, thus preventing the fixing strip 23 from loosening and affecting the stability of the device. At the same time, during the struggle of the child, the second airbag 22 can also provide a certain buffer for the child's arm, reducing the risk of damage to the child's arm. Subsequently, the other arm of the child is fixed according to the above steps to complete the fixation of the child's arms.

[0046] Subsequently, the user clips the child's leg into the fixing plate 82, and then clips it into the fixing plate 82 located on the calf through the joint elastic tube 81. The joint elastic tube 81 is adjusted to the shortest length, and the air cylinder is started to adjust the length of the extension component, thereby adjusting the distance between the side wall of the fixing plate 82 away from the stool 3 and the stool 3, so that the bottom wall of the fixing plate 82 is aligned with the child's ankle position, and the child's ankle enters between the limiting plate 92 and the stop bar 91.

[0047] Meanwhile, according to the leg muscle tension of the child, the user controls the direction of the current of the first electromagnet, so that the magnetic poles of the first electromagnet are opposite to those of the adjacent permanent magnets 54 and the first electromagnet 53 in the direction opposite to the rotation direction in turn, thereby driving the inner rod 52 to rotate. For example, when the corresponding fixing plate 82 needs to rotate to the left, by changing the current of the first electromagnet, the magnetic poles of the first electromagnet 53 are opposite to those of the rightmost adjacent permanent magnet 54 and the first electromagnet 53, so that the first electromagnet 53 attracts it, and then drives the inner rod 52 to rotate to the left. Subsequently, the current direction of the first electromagnet 53 is changed again to drive the inner rod 52 to rotate again until it rotates to an appropriate angle. Subsequently, the current magnitude of the first electromagnet is increased, so as to increase the attraction of the first electromagnet 53 to the adjacent permanent magnet 54 and the first electromagnet 54, and complete the fixation of the angle of the inner rod 52.

[0048] During the struggle of the child, the air pressure sensor continuously collects the pressure information in the first airbag 83. Since there will be no large undulations on the surfaces of the child's thigh and calf in contact with the first airbag 83, the change of the air pressure information of the first airbag 83 located at the position of the child's thigh or calf is relatively gentle and regular. During the struggle of the child, during the actions of the child lifting the leg or bending the knee, the knee squeezes the adjacent first airbag 83, causing obvious deformation of the first airbag 83. At this time, the controller judges the position of the child's joint according to the position of the first airbag 83 where the numerical value suddenly changes in the air pressure information, calculates the length of the child's calf according to the length of the fixing plate 82 and the joint elastic tube 81 and the position of the child's joint, and then the air cylinder. The inner rod 52 is pushed relative to the outer tube 51 by the air cylinder to change the distance between the fixing plate 82 and the seat 3, thereby driving the fixing piece at the position of the child's thigh to move, pulling the joint elastic tube 81 to deform, so that the fixing piece at the position of the child's thigh moves, and the center of the joint elastic tube 81 moves to the position of the child's knee. Subsequently, the controller calculates the heights of the fixed table 1 and the top wall of the seat 3 according to the length of the child's calf, and controls the corresponding electric cylinder to work according to this height, driving the tabletop or the seat surface 33 to move to the set height. At this time, when the child sits, the feet can contact the ground through the limit plate 92 and the bottom plate 11, and the thighs and calves are bent at 90 degrees. Subsequently, the controller controls the first solenoid valve to work again, so that the air pump pumps gas into the first airbag 83, so that the first airbag 83 expands to fix the child's legs. During this process, the user guides the child's legs to an appropriate position, and then activates the second electromagnet 13 at an appropriate position on the bottom plate 11, so that the second electromagnet 13 adsorbs the limit plate 92 to complete the fixation of the child's legs.

[0049] Subsequently, the first solenoid valve is closed, and the fourth solenoid valve is opened, causing the fourth airbag 6 to expand and fix to the chest of the child, reducing the displacement of the chest during the child's rehabilitation training. Subsequently, the air pump is closed to complete the fixation of the child's body. By fixing the body and limbs in sequence, this device enables the user to independently complete the debugging of the device so that the device can adapt to the child's body shape. During the entire process from completing the adaptation to fixing the child's body, no additional assistants are required to refix the child or the device itself during the subsequent training process, reducing the waste of manpower during the child's rehabilitation exercise and enabling the user to more easily assist the child in rehabilitation treatment exercises.

[0050] Based on the above solution, to help the child find the correct force during rehabilitation training, a feedback component is further included. The feedback component is used to give the child sensory stimulation. In this embodiment, the feedback component is a speaker. The control system further includes a number of flexible matrix pressure sensors. The flexible matrix pressure sensors are all fixedly connected to the side wall of the fixing strip 23 close to the child's skin by bolts. The flexible matrix pressure sensors are all used to collect the first pressure information exerted by the child's arm on the fixing strip 23. The flexible matrix pressure sensors and the speaker are both electrically connected to the controller. The controller is further used to receive the input target action and determine whether the child has the target action according to the first pressure information. After the child has the target action, the controller controls the speaker to work. Thus, during the process of fixing the child's body with this device and performing rehabilitation training, the target action is input into the controller. For example, if the child needs to maintain an extended elbow position, the flexible matrix pressure sensor collects the first pressure information exerted by the child's arm on the fixing strip 23. When facing some children with good flexor muscle tone, it is often difficult for the child to maintain an extended elbow position. When the child bends the forearm inward, the pressure exerted on the fixing strip 23 by the inner side of the forearm will increase, while the pressure exerted on the fixing strip 23 by the outer side of the forearm will decrease. That is, the pressure information collected by the flexible matrix pressure sensor on the outer side of the child's forearm becomes smaller, while the pressure information on the inner side of the child's forearm becomes larger. At this time, the user needs to guide the child to the correct position. When the child's arm reaches the correct position, the difference in the pressure information exerted by the inner and outer sides of the child's forearm on the fixing strip 23 collected by the flexible matrix pressure sensor is less than the set value. At this time, the controller controls the speaker to work, playing soothing music or playing encouraging voices, such as playing "Kid, you're amazing!", to give positive feedback to the child, encouraging the child to maintain this action during the subsequent rehabilitation training and also prompting the user that the child's arm has reached the appropriate position and the next step of rehabilitation training can be carried out.

[0051] Based on the above solution, to assist the user in rehabilitating the child's wrist, it further includes two sets of wrist movement components 7 arranged symmetrically. Each wrist movement component 7 includes a first chamber opened on the top wall of the fixed table 1. An arc-shaped notch is opened on the top wall of the first chamber. A moving plate 72 is slidably fitted in the first chamber. A grip 71 is adhesively fixed to the top wall of the moving plate 72. The grip 71 is U-shaped and extends to the outside of the first chamber through the notch. A piston 73 is slidably fitted in the first chamber. The side wall of the piston 73 and the side wall of the first chamber form a driving chamber, which is connected to an air pump. A third solenoid valve is provided at the connection. The air pump is also used to change the air pressure in the first chamber, thereby pushing the piston 73 to slide in the first chamber. Thus, when using this device, when the user needs to rehabilitate the child's wrist, guide the child to put the hand into the U-shaped interior of the grip 71. Then start the air pump and the third solenoid valve. The air pump pumps gas into the driving chamber, causing the driving chamber to expand and pushing the piston 73 to move inward. The piston 73 pushes the moving plate 72 to move, thereby driving the grip 71 to move. The grip 71 drives the child's wrist to flex. After a set time, the air pump pumps out air, the air pressure in the driving chamber drops, driving the piston 73 to move in the opposite direction, and thus moving the grip 71 to the outside through the moving plate 72, driving the child's wrist to rotate in the opposite direction for a dorsal extension movement. During this process, due to the use of air pressure drive, a certain buffer can be provided for the child's wrist, reducing the damage caused to the child's wrist by the device when the child struggles and exerts force in the opposite direction of the movement of the grip 71. At the same time, the U-shaped grip 71, compared with the solution of fixing the child's hand to the grip 71, enables the child to break free from the grip 71 in time when uncomfortable, and also facilitates the user to detach the child's hand from the grip 71 in time when observing the child's discomfort, thereby further avoiding damage to the child's hand during the rehabilitation training process.

[0052] Based on the above solution, to facilitate the correct exertion of force by the child's leg, the controller is also used to judge the force state of the child's leg according to the air pressure information, and when the force state of the child is the same as the target movement, control the first electromagnet to work. Thus, after the user fixes the child's leg through this device, close the first solenoid valve. At this time, the growth rate of the air pressure information drops rapidly, and record the initial air pressure information when the air pressure information reaches a stable state. During the rehabilitation movement of the child, children with abnormal muscle tone are prone to lower limb spasms, involuntary movements, etc. At this time, the child's lower limb squeezes the first airbag 83, causing the air pressure information inside the corresponding first airbag 83 to increase. When the difference between the real-time air pressure information and the initial air pressure information is greater than the preset value, start the first electromagnet and adjust the angle between the two inner rods 52 to help the child open the legs, which is helpful for the subsequent rehabilitation training of the child.

[0053] Based on the above solution, in order to quickly deploy the pallet 41, reduce the time for the user to manually fix the child, and lower the difficulty for the user to fix the child alone, a second chamber is provided at the connection between the second solenoid valve and the air pump, and a check valve is fixedly connected to the connection between the second chamber and the air pump by bolts. Thus, during use, after the user starts the device, the user first starts the air pump to pump gas into the second chamber, causing the gas in the second chamber to expand. In the subsequent process where the user starts the second solenoid valve to allow the gas to enter the third airbag 43 for fixing the child's waist, after the second solenoid valve is opened, under the action of air pressure, the gas quickly enters the third airbag 43, causing the third airbag 43 to quickly inflate to initially fix the child's body. Compared with the solution that only inflates through the air pump, this solution speeds up the inflation speed of the third airbag 43 by pre-storing gas, shortens the time required to fix the child's waist, reduces the time for the user to manually fix the child, and lowers the difficulty for the user to fix the child.

[0054] Based on the above solution, in order to further reduce the user's operation steps, the control system further includes a matrix pressure sensor. The matrix pressure sensor is fixedly connected to the stool surface 33 by bolts. The matrix pressure sensor is used to collect the second pressure information exerted by the child on the top wall of the seat 3, and the matrix pressure sensor is electrically connected to the controller. The controller is further used to control the air pump and the second solenoid valve to work according to the second pressure information. Thus, during use, after the device is started, the matrix pressure sensor collects the second pressure information exerted on the top wall of the stool surface 33 from the outside. When the user assists the child to sit on the stool surface 33, the second pressure information appears. According to the position of the pressure-sensitive unit of the matrix pressure sensor that collects the data, a range graph of the contact position between the child's buttocks and the stool surface 33 is constructed. When the shape of the range image tends to be stable, it means that the user has assisted the child to sit in a proper position. At this time, the air pump and the second solenoid valve are controlled to work, so that the gas in the second chamber enters the third airbag 43, reducing the user's operation steps, and the user only needs to focus on the child's body position, which is conducive to the dispersion of the user's energy and further reduces the difficulty for the user to fix the child.

[0055] Based on the above solution, to help the child maintain a relatively correct body position during training, the controller determines the area and shape of the position where the child contacts the top wall of the seat 3 according to the position where the second pressure information appears, so as to judge whether the child's pelvis is in a neutral state. When the child's pelvis is not in a neutral state, the controller controls the speaker to work. Therefore, when using this device, after the second pressure information appears, the controller connects the pressure-sensitive units with data changes in the outermost layer into a smooth closed curve according to the positions of the pressure-sensitive units of the matrix pressure sensor with data changes, calculates the area enclosed by the closed curve. At the same time, according to the shape of the closed curve, when the range enclosed by the closed curve is basically symmetric, the child's pelvis is in a relatively neutral position. When there is a large deviation between the two sides of the range enclosed by the closed curve, the child's pelvis is not in a neutral position. At this time, the controller controls the speaker to work and broadcasts a prompt voice to the user, such as "not in the appropriate position", etc., to prompt the user and help the user adjust the child's body position.

[0056] Based on the above solution, to facilitate the user to adjust the fixing strip 23 to an appropriate position and reduce the excessive pressing of the fixing strip 23 on the child's arm, which may cause discomfort to the child, the controller is also used to control the air pump and the first solenoid valve to work according to the first pressure information. Therefore, when using this device, after starting the device, the flexible matrix pressure sensor continuously collects the first pressure information exerted by the child's arm on the fixing strip 23. When the user presses the fixing strip 23 to make the fixing strip 23 contact the child's skin, after the fixing strip 23 contacts the child's skin, the first pressure information appears. As the pressing continues, all the first pressure information appears and the first pressure information is within the set range. At this time, the user presses properly. At this time, the controller controls the air pump and the first solenoid valve to work, pumps gas into the first airbag 83, deforms the limit tube 21 to fix the fixing strip 23, reducing the user's operation steps and also reminding the user to avoid continuing to press the fixing strip 23, causing excessive deformation of the fixing strip 23 and discomfort to the child.
