Description

Technical Field

[0001] The present application relates to the field of rehabilitation therapy devices, and in particular to a critical care rehabilitation chair. Background Art

[0002] With the advancement of modern medicine, the success rate of resuscitation and survival rate of critically ill patients have significantly improved. Therefore, after saving the patient's life, how to promote the patient's functional recovery, improve long-term prognosis, and return to normal life as soon as possible has become a challenge for medical staff. ICU patients often have subacute / chronic physiological and psychological problems, which can cause the patient's condition to linger, repeated infections, severe malnutrition, and prolonged hospitalization. The 2023 edition of the "Expert Consensus on Post-Critical Illness Management" clearly states that a comprehensive management strategy should be implemented during the critical recovery period to prevent and treat possible or existing ICU syndrome in patients.

[0003] Early activity is an important part of post-critical care management. Good and scientific activity training can reduce the occurrence of complications such as ICU-acquired weakness, maintain or improve the patient's physical function, reduce the occurrence of complications such as lower extremity venous thrombosis and aspiration pneumonia, accelerate the patient's recovery, effectively shorten the ICU hospital stay, and reduce the economic burden of disease treatment. However, the clinical implementation of early activity is restricted by factors such as the patient's condition, manpower, and equipment. Dubb et al. reviewed 40 studies on early rehabilitation of ICU patients and analyzed the obstacles affecting the early rehabilitation of ICU patients. Among them, structural obstacles caused by manpower and equipment and changes in patient symptoms are important obstacles. A survey of 528 medical staff by Yao Li et al. showed that more than 70% of medical staff believed that insufficient early rehabilitation treatment equipment and patient conditions were obstacles to early rehabilitation in the ICU. It can be seen that sufficient rehabilitation equipment resources and safety guarantees for patient rehabilitation are important issues that need to be addressed in the process of promoting early rehabilitation of ICU patients.

[0004] At present, medical personnel have developed technologies related to rehabilitation chairs for the needs of specialized patients for activity rehabilitation, mainly in specialized wards such as orthopedics, neurosurgery, ophthalmology, and general surgery. The functions realized include fixed support traction using brackets, air cushions to increase comfort, air bags to prevent pressure injuries, electric heating tubes to heat, drive motors to simulate walking exercises, fumigation and washing cylinders, straps to fix and protect, traditional Chinese medicine acupuncture, leg flexion and extension exercises, etc. The shortcomings of the above existing technologies are summarized as follows: 1. Lack of intelligent vital sign monitoring is not conducive to ensuring the safety of critically ill patients during activity rehabilitation; 2. Lack of comprehensive functions is not conducive to meeting the diverse rehabilitation needs of patients at the same time; 3. Ignoring the psychological and cultural needs of patients is not conducive to improving the exercise effect and improving the quality of rehabilitation from the physiological, psychological, and social aspects.

[0005] The Chinese patent number "CN112641572A" and the patent name "A Health Monitoring and Rehabilitation Wheelchair" discloses a wheelchair with monitoring function, but it lacks training function and interactive function, and will not make targeted changes for specific users. It is equivalent to a simple superposition of monitoring equipment and wheelchair functions.

[0006] The Chinese patent number "CN108969308A" and the patent name "A lower limb rehabilitation robot" discloses a rehabilitation training device, but it is driven by a cylinder and can only perform passive exercise well, and cannot perform active exercise. Summary of the invention

[0007] The present application provides a critical care rehabilitation chair to at least solve the technical problems of rehabilitation training existing in the prior art.

[0008] According to the present application, a critical care rehabilitation chair is provided, including a drive switch, a control circuit, a swing arm, a strap, a drive member and a support portion, wherein the support portion mainly supports the human body, and the strap is installed on the swing arm. The control circuit drives the swing arm to rotate forward and reverse relative to the support portion by controlling the forward and reverse rotation of the drive member. The drive switch is controlled by the strap and is triggered when the strap is stretched. The drive switch controls the drive member by feeding back an electrical signal to the control circuit, so that when the drive switch is triggered, the control circuit controls the drive member to drive the swing arm to rotate.

[0009] Compared with the prior art, the critical care rehabilitation chair of the present application has the following beneficial effects: The critical care rehabilitation chair can be used for active rehabilitation training and passive rehabilitation training. Passive rehabilitation training is mainly for patients with complete paralysis such as stroke. Due to factors such as inability to move or small movement force and slow movement, the part that needs rehabilitation training can be fixed on the swing arm, and the swing arm can be driven by the driver to move, so that the human body can perform passive training. Passive training does not need to trigger the drive switch, and the program can be used to directly control the driver to drive the swing arm to move regularly; active rehabilitation training is mainly for people who are slow in movement, inflexible in movement, or can only perform small-range movements due to factors such as severe illness. This group of people can make small movements. Under the action of small movements, the strap can be pulled to trigger the drive switch, and under the control of the control circuit, the driver can drive the swing arm to rotate, so that large-scale training movements can be completed. The control circuit can be controlled by a program, and different training modes can be set for different groups of people, such as power-assistance mode and resistance mode. The power-assistance mode can make training easier, and the resistance mode can increase the difficulty of training, that is, increase the intensity of training.

[0010] In one embodiment, the support portion includes a backrest, a left seat plate, a right seat plate, a support frame and armrests. The left seat plate and the right seat plate are fixed to the support frame in a rotatable manner relative to the support frame. The armrests are arranged on both sides of the left seat plate and the right seat plate. The backrest is arranged behind the left seat plate and the right seat plate and can be rotated relative to the left seat plate and the right seat plate. This design allows the user to move multiple joints during rehabilitation training, especially the thighs and waist. In some embodiments, upright movement training can be performed to meet the requirements of different users.

[0011] In one possible implementation, the triggering principle of the driving switch is to convert the physical displacement or pulling force into an electrical signal, that is, to trigger it through a pressure sensor, or the driving switch is a plurality of travel switches, and the strap has a certain elasticity and can be stretched to different travel switch positions under different forces to trigger different travel switches; or, the driving switch is a resistance switch, and the strap has a certain elasticity and can be stretched to different positions under different forces so that the switch has different resistance values. This design structure is simple, and the reaction speed of the driving component can be adjusted according to the strength of the user, that is, the greater the force on the strap, the faster the driving component speed.

[0012] In one embodiment, the swing arm includes a left leg swing arm and a right leg swing arm. The left leg swing arm is hinged to the left seat plate so that the left leg swing arm can rotate relative to the left seat plate, and the right leg swing arm is hinged to the right seat plate so that the right leg swing arm can rotate relative to the right seat plate. The left leg swing arm and the right leg swing arm are controlled by a driving switch and driven by a driving member, so that training of the left and right legs can be performed separately, including active training and passive training.

[0013] In one embodiment, the swing arm includes a first left arm, a second left arm, a first right arm and a second right arm, the first left arm and the first right arm are symmetrically designed, the first left arm is connected to the backrest by a three-degree-of-freedom active ball joint mechanism based on spherical gear meshing, so that the first left arm can rotate relative to the backrest, the first left arm and the second left arm are connected by a three-degree-of-freedom active ball joint mechanism based on spherical gear meshing, so that the first left arm can rotate relative to the second left arm, the three-degree-of-freedom active ball joint mechanism is driven by multiple driving parts, the first right arm and the second right arm and the first left arm and the second left arm adopt the same transmission design, so that training of left and right rotation in multiple directions can be performed, which is closer to the movement law of human arms and can perform complex movements. In one embodiment, the intensive care rehabilitation chair is equipped with a vital signs monitoring device that can monitor the user's heart rate, respiratory rate, blood oxygen saturation and blood pressure in real time. An acupoint massage device is provided at the contact position between the intensive care rehabilitation chair and the human back, buttocks, legs and soles of the feet, which can massage the corresponding acupoints. This can better monitor the user's real-time vital signs and avoid accidents to the trainee.

[0014] In one possible implementation, the intensive care rehabilitation chair is equipped with an interactive system that can communicate and converse with the user, encourage the user during the exercise, praise the user after completing the exercise, and choose to broadcast or play multimedia content according to the user's personal preferences during use.

[0015] In one possible implementation, the interactive system of the critical care rehabilitation chair is provided with an intelligent evaluation prediction module, which compares and evaluates or predicts the training status of the day by using historical training data and the training data of the day. The historical training data includes at least one of the historical training time length, historical training intensity, historical training type, historical training frequency, historical training heart rate, and historical training personnel status. The training data of the day includes at least one of the training time length, training intensity, training type, training frequency, training heart rate, and training personnel status of the day. When the training data of the day is significantly lower than the historical training data, it is evaluated as poor, when the training data of the day is slightly worse than the historical training data, it is evaluated as medium, when the training data of the day is slightly better than the historical training data, it is evaluated as good, and when the training data of the day is significantly better than the historical training data, it is evaluated as excellent. The evaluation result can be used as the evaluation basis of the user's physical condition. The evaluation of poor and excellent can be confirmed by medical personnel based on the actual situation, whether it is affected by external environmental factors, and interference factors are eliminated as much as possible to determine a reasonable physical state.

[0016] In one embodiment, when the intelligent evaluation prediction module is evaluated as poor, the data is transmitted to the medical staff through the background, and the medical staff goes to the site to judge the user's physiological condition and determines whether to continue to exercise according to the actual situation; when the intelligent evaluation prediction module is evaluated as medium, the power-assisting time and the speed of the driving member are increased so that the user can perform various actions more easily, and the interactive system sends an encouraging voice to encourage the user to continue training; when the intelligent evaluation prediction module is evaluated as good, the interactive system sends a praising voice; when the intelligent evaluation prediction module is evaluated as excellent, the data is transmitted to the medical staff through the background, and the medical staff goes to the site to judge the user's physiological condition and determines whether it exceeds the reasonable intensity according to the actual situation. If all indicators are normal and do not exceed the reasonable training intensity, the power-assisting time and speed can be appropriately adjusted. In this way, a more reasonable training intensity can be given to the user. When the user's body is abnormal, the medical staff can discover and intervene in time to avoid unexpected situations. Too high training intensity will also be counterproductive, so the user needs to train with a reasonable intensity.

[0017] In one embodiment, the interactive system is provided with a power-assisted training mode and a resistance training mode. In the power-assisted training mode, once the driving switch is triggered, the driving member will rotate at a certain speed along the force direction of the strap for a certain time. In the resistance training mode, once the driving switch is triggered, the driving member will provide a certain resistance to limit the rotation. The interactive system is provided with a cycle training module. For the first use, the actual training intensity is confirmed by the user and medical staff, and a certain time is a training cycle. In a training cycle, the power-assisted time and speed are gradually increased to make the user's training easier and easier; after a training cycle, the second training cycle begins, and the second training cycle increases the training intensity by one level. If the training intensity on the first day exceeds the user's tolerance range, the medical staff may make appropriate adjustments. If the user can bear it, the increase in the power-assisted time and speed of the second training cycle is less than that of the first training cycle; after the second training cycle, the third training cycle will be started depending on the situation, and the steps of the second training cycle will be repeated. In this way, when users use it for the first time, the first training cycle will become easier and easier, and they will think that the training effect is very obvious, which greatly increases the confidence of rehabilitation training and makes the training more motivated. Rehabilitation training is not necessarily the higher the intensity, the better. The key is to persist in training. If the same training is performed every day, users will easily get bored and lack confidence in training. It is difficult for users with insufficient perseverance to persist in training. The confidence brought to users by a training cycle is more important than the actual improvement of physical fitness. Therefore, this cycle training module is very suitable for severe rehabilitation training. In the later rehabilitation training of users, in order to increase the training intensity, resistance mode training can be used, so that the training intensity is higher and the training effect is better.

DETAILED DESCRIPTION

[0021] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a critical care rehabilitation chair includes a driving switch 5, a control circuit, a swing arm 4, a strap 3, a driving member 2 and a support portion 1. The support portion 1 mainly supports the human body. The strap 3 is installed on the swing arm 4. The control circuit drives the swing arm 4 to rotate forward and reverse relative to the support portion 1 by controlling the driving member 2 to rotate forward and reverse. The driving switch 5 is controlled by the strap 3 and is triggered when the strap 3 is stretched. The driving switch 5 controls the driving member 2 by feeding back an electrical signal to the control circuit, so that when the driving switch 5 is triggered, the control circuit controls the driving member 2 to drive the swing arm 4 to rotate.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, in one embodiment, the support part 1 includes a backrest 11, a left seat plate 12, a right seat plate 13, a support frame 14 and an armrest 15. The left seat plate 12 and the right seat plate 13 are fixed to the support frame 14 in a rotatable manner relative to the support frame 14. The armrest 15 is arranged on both sides of the left seat plate 12 and the right seat plate 13. The backrest 11 is arranged behind the left seat plate 12 and the right seat plate 13 and can rotate relative to the left seat plate 12 and the right seat plate 13. For some users who are undergoing severe rehabilitation training, they may need to train their thighs and waist, especially passive training, which requires the drive member 2 to drive the backrest 11, the left seat plate 12 or the right seat plate 13 to rotate. For active training, an auxiliary power function is provided, or resistance is increased to improve the training intensity.

[0024] In one embodiment, the triggering principle of the drive switch 5 is to convert the pulling force into an electrical signal, that is, to trigger it through a pressure sensor. Different trigger sensitivities need to be set for different users. For example, for patients recovering from critical illness who are relatively weak in the early stage and may not be able to provide too much force, the force of the trigger switch can be set to about 10 N to 20 N. For users in better condition, in order to avoid false triggering of the switch, the switch trigger force can be set to 50 N to 80 N. This setting can be adjusted by medical staff through software for different users to achieve the best effect. In addition, when the pressure sensor detects a larger force, it means that the user is moving faster, and the speed and reaction time of the drive member 2 can be increased to cooperate with the user to complete the action.

[0025] In one embodiment, the triggering principle of the driving switch 5 is to convert physical displacement into an electrical signal. The driving switch 5 is a plurality of travel switches 51. The strap 3 has a certain elasticity and can be stretched to different travel switch 51 positions under different forces to trigger different travel switches 51. The travel switch 51 has a longer service life than other switches. Figure 5 As shown, the travel switch 51 can be driven by a magnet 54, which can be arranged in a sleeve 52 and reset by a spring. A plurality of pairs of contacts are arranged outside the sleeve 52, and the outer contact 53 is provided with a magnet 55 which can attract the magnet 54. When the magnet 54 moves close to the magnet 55, the contact can be attracted. This design has a simple structure and reliable performance.

[0026] In one embodiment, the drive switch 5 is a resistance switch. The strap 3 has a certain elasticity and can be stretched to different positions under different forces so that the switch has different resistance values. The change in resistance basically corresponds to the change in the magnitude of the pulling force. The greater the pulling force of the strap 3, the faster the drive member 2 needs to react to make the training movement smoother. The resistance switch can achieve stepless changes and can correspond to different rotation speeds of the drive member 2, so that the movement is easier. When the drive switch 5 is triggered, the control circuit controls the drive member 2 to rotate along the force direction of the strap 3, and the rotation speed can be changed according to the force magnitude of the strap 3.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the swing arm 4 includes a left leg swing arm 41 and a right leg swing arm 42. The left leg swing arm 41 is hinged to the left seat plate 12 so that the left leg swing arm 41 can rotate relative to the left seat plate 12. The right leg swing arm 42 is hinged to the right seat plate 13 so that the right leg swing arm 42 can rotate relative to the right seat plate 13. The left leg swing arm 41 and the right leg swing arm 42 are controlled by the drive switch 5 and driven by the driven member 2. Figure 1 The left leg swing arm 41 rotates to a vertical state, and the right leg swing arm 42 rotates to a horizontal state.

[0028] like Figure 4 As shown, in one embodiment, by increasing the height of the support frame 14 and rotating the backrest 11, the left seat plate 12 and the right seat plate 13, the upright training function can be achieved, and falling can be prevented under the action of the support frame 14, so that different groups of people can be adapted to perform training of different movements.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the swing arm 4 includes a first left arm 43, a second left arm 44, a first right arm 45 and a second right arm 46. The first left arm 43 and the first right arm 45 are symmetrically designed. The first left arm 43 is connected to the backrest 11 through a three-degree-of-freedom active ball joint mechanism 47 based on spherical gear meshing, so that the first left arm 43 can rotate relative to the backrest 11. The first left arm 43 and the second left arm 44 are connected through a three-degree-of-freedom active ball joint mechanism 47 based on spherical gear meshing, so that the first left arm 43 can rotate relative to the second left arm 44. The three-degree-of-freedom active ball joint mechanism 47 is driven by multiple driving parts 2, and the first right arm 45 and the second right arm 46 adopt the same transmission design as the first left arm 43 and the second left arm 44.

[0030] The three-degree-of-freedom active ball joint mechanism 47 or the driving member 2 is provided with a wheel speed sensor capable of detecting the direction and speed of rotation. In this way, during active training, the rotation speed and direction are first detected and then assistance is provided through the rotation speed and direction. The time for each assistance is no more than 2 seconds. As a preference, it can be set between 0.3 seconds and 2 seconds. After stopping the assistance, if the speed drops quickly, it can be considered that there is no active action. Stop the assistance immediately or provide a reverse force to resist the inertial rotation to ensure that the action stops quickly. After stopping the assistance, if the speed drops slowly, it can be considered that there is an active action. Continue to provide the next assistance and adjust the assistance rotation direction according to the current rotation direction. Generally speaking, the assistance time is best at about 0.8 seconds, and then adjust according to the active movement direction. The rotation speed of the assistance is above 100 revolutions per minute.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the three-degree-of-freedom active ball joint mechanism 47 is fixed on an adjustment rod 48, and the adjustment rod 48 can adjust the horizontal position of the three-degree-of-freedom active ball joint mechanism 47. The adjustment rod 48 is fixed on an upgrade platform 49, and the lifting platform 49 can realize a lifting function to adjust the vertical height of the three-degree-of-freedom active ball joint mechanism 47.

[0032] In one embodiment, the swing arm 4 includes a first left arm 43, a second left arm 44, a first right arm 45, and a second right arm 46. The left and right sides are symmetrically designed. The first left arm 43 and the second left arm 44 are hinged and driven by the driving member 2. The first left arm 43 and the first right arm 45 have the same structure as the left leg swing arm 41 and the right leg swing arm 42. This structure is simple. To ensure that the user needs to rotate in different directions for training, a plurality of mutually perpendicular hinge shafts can be set at the hinge position. The hinge shaft in one direction is provided with a driving structure, and the other hinge shafts are provided with a locking structure, that is, adjusted to a suitable position and locked. Of course, a driving member 2 can also be provided on each hinge shaft, which is more expensive and occupies a larger space, but can complete complex rotation movement training and can be set according to the needs of training.

[0033] In one embodiment, a 3D camera may be used to identify the user's movements and then provide assistance, or the user may wear multiple sensors to identify the movements, or other human body motion posture recognition developed in the future may be used.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, the critical care rehabilitation chair is provided with a display panel 16, which is a terminal system integrating display, calculator, processor and other components. The display panel 16 is mounted on the support frame 14 through a foldable multi-rod structure 17. The display panel 16 can be fixed at multiple angles and multiple positions, and the display panel 16 can be operated by touch. The display panel 16 controls the driving member 2 by controlling the control circuit, and the electrical signal of the driving switch 5 can also be directly fed back to the display panel 16. The display panel 16 can be installed with different training software for different rehabilitation training, and can be customized.

[0035] In one embodiment, the critical care rehabilitation chair is provided with a vital sign monitoring device connected to the display panel 16, which can monitor the user's heart rate, respiratory rate, blood oxygen saturation and blood pressure in real time. The user can wear a corresponding vital sign monitoring structure, or set a monitoring structure at a position that can contact the human skin, or use an optical fiber sensor device to convert the optical signal into an electrical signal output, and transmit the patient's real-time vital signs to the display panel 16. This design can, firstly, visually feedback the vital signs and exercise data in real time for easy observation, and the touch screen design facilitates the setting of operating parameters and function locking; secondly, intelligent alarms are realized through threshold setting; thirdly, intelligent voice prompts increase human-computer interaction to give positive incentives and improve the patient's participation experience in rehabilitation exercises.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, an acupoint massage device 18 is provided at the contact position between the intensive care rehabilitation chair and the back, buttocks, legs and soles of the human body, and can massage the corresponding acupoints.

[0037] In one embodiment, the rear end base of the critical care rehabilitation chair has an infusion stand with an adjustable aperture size to meet the patient's necessary infusion requirements during exercise. According to the common pressure injury sites of the human body, air cushions are added in various places to prevent injuries. Tracks and hooks are designed on both sides of the abdominal position of the critical care rehabilitation chair to facilitate the hanging and moving of drainage bags (bottles), ensuring that the drainage bags (bottles) are in the appropriate position when using the rehabilitation chair, so that the pipelines are properly fixed and the drainage is unobstructed. The hand supports on both sides of the critical care rehabilitation chair are detachable, and the patient can choose any side to move to the rehabilitation chair to reduce movement obstacles.

[0038] In one embodiment, the display panel 16 of the intensive care rehabilitation chair is installed with an interactive system that can communicate and converse with the user. The interactive system is a program system developed based on software. It encourages the user during the exercise process, praises the user after completing the exercise, and chooses to broadcast or play multimedia content according to the user's personal preferences during use.

[0039] In one embodiment, the interactive system of the intensive care rehabilitation chair is provided with an intelligent evaluation and prediction module, which compares historical training data with the current day's training data to evaluate or predict the current day's training status. The historical training data includes at least one of the historical training time length, historical training intensity, historical training type, historical training frequency, historical training heart rate, and historical training personnel status. The current day's training data includes at least one of the current day's training time length, current day's training intensity, current day's training type, current day's training frequency, current day's training heart rate, and current day's training personnel status. When the current day's training data is significantly lower than the historical training data, it is evaluated as poor; when the current day's training data is slightly worse than the historical training data, it is evaluated as medium; when the current day's training data is slightly better than the historical training data, it is evaluated as good; and when the current day's training data is significantly better than the historical training data, it is evaluated as excellent. The reference standard for evaluation can be 10%-30% fluctuation of historical training data. For example, if the historical training time is 60 minutes and the training time on the day exceeds 72 minutes, it can be evaluated as excellent, less than 48 minutes is poor, 48 minutes to 60 minutes is medium, and 60 minutes to 72 minutes is good. The historical training frequency is 30 times per minute, and the frequency is more than 33 times, which is excellent, the frequency is less than 26 is poor, the frequency is 26-30 is medium, and the frequency is 30-33 is good. Generally, multiple data are used for evaluation at the same time. Each data is first evaluated according to the percentage system, and then the overall evaluation is comprehensively carried out, or the medical staff specifies targeted evaluation standards according to individual circumstances. Different types of training are usually not compared. The same type of training can be judged according to training time, training intensity and training frequency. The training heart rate is used as an auxiliary evaluation parameter, which basically does not affect the evaluation results within a reasonable range.

[0040] In one embodiment, when the intelligent evaluation and prediction module is evaluated as poor, the data is transmitted to the medical staff through the background, and the medical staff goes to the site to judge the user's physiological condition and determines whether to continue exercising according to the actual situation; when the intelligent evaluation and prediction module is evaluated as medium, the assisting time and the speed of the driving member 2 are increased so that the user can perform various actions more easily, and the interactive system emits an encouraging voice to encourage the user to continue training; when the intelligent evaluation and prediction module is evaluated as good, the interactive system emits a praising voice; when the intelligent evaluation and prediction module is evaluated as excellent, the data is transmitted to the medical staff through the background, and the medical staff goes to the site to judge the user's physiological condition and determines whether it exceeds the reasonable intensity according to the actual situation. If all indicators are normal and do not exceed the reasonable training intensity, the assisting time and speed can be appropriately adjusted.

[0041] refer to Figure 6In one embodiment, the training intensity gradually decreases within a training cycle. In the figure, the horizontal axis is the training time, and the vertical axis is the training intensity. Under normal training conditions, the training intensity gradually increases within different training cycles. The interactive system is provided with an assist training mode and a resistance training mode. In the assist training mode, once the drive switch 5 is triggered, the drive member 2 will rotate at a certain speed along the force direction of the strap 3 for a certain time. In the resistance training mode, once the drive switch 5 is triggered, the drive member 2 will provide a certain resistance to limit the rotation. The interactive system is provided with a cycle training module. The actual training intensity is confirmed by the user and medical staff for the first time. The lower the training intensity, the longer the assist time or the faster the assist speed or the smaller the resistance. A certain time is a training cycle, such as five days or ten days as a training cycle. In a training cycle, the assist time and speed are gradually increased to make the user's training easier and easier; after a training cycle ends, the second training cycle begins. The second training cycle increases the training intensity by one level. For reference Figure 7 If the training intensity on the first day exceeds the tolerance of the user, the medical staff can make appropriate adjustments to reduce the difficulty of training. However, in theory, the minimum training intensity should also exceed the training intensity of the previous cycle. The maximum training intensity is set according to the specific situation. If the user cannot adapt to a large change in training intensity, the training intensity change within a cycle can be reduced. For example, the original daily change range is more than 5%, which can be reduced to 2% daily. The change can be in the assist time or speed. If the user can bear it, refer to Figure 6 , the increase in the assist time and speed of the second training cycle is less than that of the first training cycle; after the second training cycle, the third training cycle will be started as appropriate, and the steps of the second training cycle will be repeated. After multiple training cycles, the range of change in a single training cycle needs to be smaller and smaller, so as to avoid being discovered by the user. Once discovered, the effect of the mode on improving rehabilitation training may be ineffective. Therefore, a reasonable range of change should be specified for different groups of people, which can be specified by medical personnel according to specific circumstances.

[0042] refer to Figure 8 The interactive system operation process is as follows: first, press the power button, confirm or enter the user's basic information, measure the user's basic vital signs, and then the medical staff confirms the patient's safety and sets a reasonable vital sign alarm threshold. Combined with the user's physical condition and individual preference needs, select function parameters, such as activity parameters, massage parameters, and leisure and entertainment parameters. After the medical staff and the patient confirm that everything is correct, lock the screen and select one-key operation. Reference Fig. 9 This interface is a reference interface for the interactive system. Different interfaces can also achieve the same function, so it is not limited in the claims.

[0043] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this application can be executed in parallel, sequentially or in different orders, as long as the expected results of the technical solution of this application can be achieved, and this document does not limit this.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
